Definitions

  • the invention relates to a blocking unit according to claim 1 for a shaft structure that can be closed with a manhole cover, as well as to a device set of a closure system comprising such a blocking unit. Furthermore, the invention relates to a shaft structure, in particular a sewage shaft, that can be closed with a manhole cover and has at least one partial volume that can be separated from the remaining shaft volume and closed with a closure system. The present invention also relates to a method according to claim 15 for rehabilitating a shaft structure.
  • Shaft structures are essential components of public and private infrastructure facilities. Shaft structures make it possible to lay underground infrastructure lines, such as sewage, water, power, or telecommunications lines, over long distances, connect them in network structures, maintain them, and, if necessary, replace them.
  • underground infrastructure lines such as sewage, water, power, or telecommunications lines
  • Shaft structures typically have a cavity located underground or embedded in another structure, which is accessible through an opening and can be closed with a shaft closure or manhole cover on the surface.
  • Infrastructure lines of the respective infrastructure facilities such as pipelines, channels, gutters, and/or cables, then open into the cavity of the shaft structure and/or are routed through it. This makes it possible to combine or separate infrastructure lines within the shaft structure, to change their direction, or to bridge heights. Infrastructure lines in or through the shaft structure can be inspected, maintained and/or cleaned.
  • Older sewer networks based on combined systems are typically renovated in such a way that the existing manhole structure is used only for the wastewater sewer network, while an additional manhole structure is built next to it for the stormwater sewer network - or vice versa.
  • This increases the space required for the renovation of older sewer networks in the area of the manhole structures, but This is particularly problematic in locations with limited underground space, such as urban areas with a high density of underground infrastructure or in the vicinity of tram and train tracks, which are sensitive to ground movement.
  • the EP 3 696 330 (Renggli ) describes in this context a device set of a closure system for a shaft structure that can be closed with a manhole cover.
  • shaft structures can be created in which two or more infrastructure lines running through a shaft structure in the same shaft structure can be separated from one another in a liquid-tight manner using a closure.
  • the closure system includes, among other things, a locking unit for the shaft cover, wherein the locking unit can assume a locked position and a neutral position, and wherein the locking unit is designed such that, when installed in the locked position, it prevents a manhole cover from being completely closed, while in the neutral position it allows the manhole cover to be completely closed.
  • the locking unit can be designed such that a locking element of the locking unit is supported and/or hooked onto a guide of the locking element in the locked position and is thus blocked. This prevents the locking element from being moved from the locked position to the neutral position due to the unintentional action of large forces, e.g. due to the stepping of people.
  • the object of the invention is therefore to provide improved and safer solutions for the renovation and/or construction of shaft structures for infrastructure facilities.
  • advantageous devices and/or methods are to be provided with which shaft structures for infrastructure facilities can be constructed or renovated in the safest, most space-saving, most cost-effective, and/or simplest manner possible. This is particularly true in connection with infrastructure facilities in which several different infrastructure lines must be routed separately from one another.
  • corresponding devices and methods are to be provided for wastewater systems with separate sewer networks for wastewater and rainwater.
  • Locking element is blocked, wherein the guide is a linear guide and the locking element and locking element are mounted in the same linear guide.
  • Such a blocking unit is particularly suitable for reliably preventing a shaft structure from being closed with its associated manhole cover if the shaft structure or its internal components, such as a closure, are not in the required configuration. This can be achieved in particular by coupling the blocking unit to the internal components of the shaft structure, e.g., a closure that provides a fluid-tight separation between various infrastructure lines running through the shaft structure.
  • the locking unit also features a locking element in addition to the locking element, which locks the locking element in the locked position, the locking element can be further protected against unauthorized movement. Accordingly, to unlock the locking element, the locking element must also be released or moved into the release position. This significantly reduces the risk of unauthorized movement of the locking element from the locked position to the neutral position.
  • the locking element In the locked position, the locking element interacts with the locking element to block the locking element and prevent it from moving from the locked position and/or into the neutral position. However, when the locking element is in the release position, it releases the locking element, allowing it to be moved into the neutral position.
  • the guide of the locking unit is a linear guide, in particular a cuboidal groove and/or a cuboidal cavity. This allows the locking element to be moved out of the guide, for example, along a straight line, which has proven advantageous and reliable for applications in shaft structures.
  • a linear guide can be used to create a particularly compact locking unit.
  • the guide is installed directly beneath the shaft cover in the shaft structure so that the locking element can be moved toward the shaft opening, a relatively small translation of the Locking element to prevent the shaft structure from being closed with the shaft cover.
  • the guide is preferably designed as a U-shaped profile strip, with the locking element guided in the concave area of the U-shaped profile. Further preferably, the U-shaped profile strip is closed along its longitudinal axis with a cover. This creates a guide channel in the form of a cuboidal cavity.
  • the locking unit can comprise a rotatably mounted locking element, e.g., a bolt.
  • the bolt can be mounted and designed such that it can be moved from a horizontal orientation (neutral position) to a vertical orientation (locking position) in the area of the shaft opening.
  • An asymmetrically mounted disc, which can be pivoted into the shaft opening, is also possible as a locking element.
  • the locking unit is designed such that the guide runs vertically when the locking unit is mounted.
  • the force of gravity can be used to move the locking element and/or the locking element in one of the directions within the guide or to assist the movement. This allows, for example, certain positions, such as the locking position of the locking element, to be reached automatically.
  • the locking element and the arresting element are mounted in the same guide, in particular a linear guide. This significantly simplifies the design. Furthermore, this measure has been shown to achieve a high level of reliability and robustness of the locking unit.
  • the locking element and the locking element are in direct contact in the guide.
  • the locking unit is designed such that when the locking element is in the locking position, the locking element is automatically moved into the locking position, preferably by the action of the gravitational force and/or a spring force.
  • the locking unit is designed such that the center of mass of the locking element in the release position is located vertically at a height that is higher than the height of the locking element in the locking position. This allows the locking element to be moved from the release position to the locking position purely by gravitational force, for example, particularly once the locking element has reached the locking position. This ensures that the locking element is always moved to the locking position without the need for additional measures.
  • the locking unit is designed such that the locking element can additionally assume a neutral position which differs from the release position and the locking position.
  • the locking unit is designed such that a center of mass of the locking element in the neutral position is present in the vertical direction at a height which is above the height of the locking element in the locking position and below a height of the locking element in the release position.
  • the locking element closes the guide in the neutral position together with the locking element when the latter is in the neutral position. This prevents dirt from entering the guide and allows for a compact design of the locking element.
  • other designs are also possible in which the locking element does not close the guide.
  • the locking unit is designed such that the locking element rests on the locking element in the neutral position and/or in the release position. This prevents the locking element from falling downward out of the guide when the guide runs vertically. Furthermore, this measure ensures that the locking element is automatically moved along with the locking element when it moves.
  • the locking unit is designed such that the locking element is supported in the locking position, in particular on a base. This additionally prevents the locking element from being disengaged from the locking position due to the unintentional impact of large forces, such as the impact of people or vehicles driving over it.
  • the locking position can be moved to the neutral position.
  • other support measures are also possible.
  • the locking element is a strip-shaped element having an end portion protruding perpendicularly to a longitudinal axis of the strip-shaped element at a first end and/or a projection protruding perpendicularly to the longitudinal axis of the strip-shaped element at the opposite end.
  • the end portion is the area that can be moved out of the guide to achieve the locking effect.
  • the locking unit has a base, in particular a base arranged in the guide.
  • the base is designed such that the locking element rests on it in the neutral position and, more preferably, is completely accommodated in the guide. If the guide runs vertically, this prevents the locking element from slipping out of the guide at the bottom.
  • the freedom of movement of the locking element in all directions is limited by a base mounted in the guide.
  • the base is preferably designed as a stop for the end section and/or the projection of the locking element; in particular, the base is arranged between the end section and the projection.
  • the locking unit is designed such that the locking element is supported on the base in the locking position.
  • the locking element has a recess between the end section and the projection, in particular a rectangular recess, which has a length that essentially corresponds to a length of the base in the longitudinal direction of the guide and/or which has a width that essentially corresponds to a width of the base in a direction perpendicular to the longitudinal direction of the guide.
  • the recess is dimensioned such that the locking element, when positioned with the recess in the area of the base, can at least partially encompass the base in the area of the recess. This allows the locking element to be supported on the base in the locked position.
  • the locking element is a strip-shaped element which has a first angled end region at its first end and a second angled end region at its opposite end, wherein the first and the second angled end region preferably extend perpendicular to a longitudinal axis of the locking element.
  • the locking element encompasses the blocking element in the release position and/or the neutral position with the two angled end areas.
  • a length of the locking element in the longitudinal direction advantageously corresponds approximately to a length of the free space between the angled end regions of the locking element or the length of the locking element is smaller.
  • the locking unit is designed such that the locking element performs a linear movement and/or a rocking movement when moving from the neutral position to the locked position.
  • a linear movement and a rocking movement are particularly preferably, a linear movement and a rocking movement.
  • the locking unit is designed such that the locking element can perform a rocking movement when the locking element protrudes maximally from the guide and the locking element is in the release position.
  • the locking unit is designed such that the locking element, when it is in the neutral position, is moved into the release position by a movement of the locking element, in particular a linear movement.
  • the locking element preferably with the first angled end region, rests on the blocking element in the neutral position, in particular on the end section of the blocking element. This allows the locking element to be moved along with the movement of the blocking element from the neutral position to the blocking position.
  • the locking element in particular the end section of the locking element, has a beveled support surface for the locking element, in particular for the first angled end region of the locking element.
  • Beveled means that the surface is at an angle of 5-95°, in particular 5-50°, to the horizontal. Due to the bevel, the weight of the locking element generates a force component acting in the horizontal direction, which causes the locking element, when it protrudes far enough from the guide, to perform a tilting movement and thus be moved into the locked position. In this process, the locking element, in particular, is released, so that it is moved downward into the locked position by the force of gravity.
  • the locking element projects out of the guide in the locking position and is supported on the base body and/or the base, wherein the longitudinal axis of the locking element runs obliquely to the longitudinal axis of the guide and/or obliquely to the longitudinal axis of the locking element.
  • the first angled end portion of the locking element blocks the locking element in the locking position, thus preventing a tilting movement of the locking element.
  • the first angled end portion of the locking element is preferably lowered into the guide in the locking position.
  • the first angled end portion of the locking element protrudes from the guide in the release position and/or the first angled end portion of the locking element is lowered into the guide in the locking position.
  • the locking element has an actuating element, in particular a handle, for manually moving the locking element from the locking position to the release position. This allows the locking element to be moved into the release position by a defined movement.
  • the locking unit has an interface for connecting a mechanical coupling element, in particular a cable and/or a Double gear for the locking element. This allows the locking element to be automatically controlled or moved into the locking position by a process inside the shaft structure, such as the opening of a lock.
  • the locking element is connected to a mechanical coupling element, in particular a cable and/or a coupling gear.
  • the locking element is preferably coupled to the closure by means of a mechanical coupling element, in particular a cable and/or a coupling gear.
  • the locking element Due to the locking element of the locking unit, the locking element can only be moved from the locked position if the locking element is moved into the release position or is in this position.
  • Such a device set can be used to create shaft structures in which two or more infrastructure lines running through a shaft structure can be separated from each other in a fluid-tight manner within the same shaft structure.
  • a sub-volume can be created in an existing shaft structure or in a newly constructed shaft structure, which can then be opened or closed with the closure according to the invention.
  • the detachable volume and the remaining volume are completely separated from each other. However, if the locking unit is in the release position and the closure is opened, the detachable volume can be accessed from the remaining volume. This allows access to the individual infrastructure lines through a single shaft structure with a single shaft cover if necessary, e.g., for maintenance work. During normal operation, the infrastructure lines are routed completely separately through the same shaft structure.
  • the locking unit for the manhole cover and its coupling to the closing unit ensures that the shaft structure can only be closed when the lock is correctly and completely engaged. This ensures that the detachable volume and the remaining shaft volume are securely separated from each other when the manhole cover is closed. Incorrect manipulation is thus virtually eliminated.
  • a single shaft structure can be used to create a system that enables the separation of different infrastructure lines just as reliable and secure as a conventional separation system, in which access to the infrastructure lines is provided via separate shaft structures.
  • the inventive equipment kit thus makes it possible to renovate existing shaft systems while maintaining the same space requirements, allowing them to be used for separation systems. Furthermore, new shaft systems can be designed directly for separation systems using the inventive equipment kit. In both cases, this results in significant cost and space savings, both underground and on the surface, where only a single manhole cover is required.
  • construction and renovation work can be significantly simplified using the equipment set according to the invention.
  • significantly smaller and easier-to-operate construction sites are possible for construction and renovation work compared to conventional separation systems.
  • For new construction for example, significantly smaller trench profiles are required, while for renovation work or the conversion of an older mixed system to a separation system, the ground does not need to be opened at all, as the renovation can be carried out directly in the existing shaft.
  • the device set according to the invention is particularly interesting for the renovation or construction of shaft structures for wastewater infrastructure lines.
  • Many older wastewater infrastructures still exist in which stormwater pipes and wastewater pipes are routed through shared shaft structures, so-called combination shafts.
  • the closure is advantageously designed as a lid, in particular as a lid that can be completely removed from the socket and/or as a lid that can be completely detached from the socket.
  • a lid is a substantially rectangular, square, circular, or elliptical lid.
  • the lid is, in particular, a flat part whose height in the direction of the passage to be closed is smaller than a length and a width of the lid or smaller than a diameter of the lid.
  • other shapes are also possible in principle.
  • a cover that can be completely removed from the socket and/or a cover that can be completely detached from the socket has the particular advantage that the cover or a hinge
  • the cover does not obstruct access to the infrastructure line in the enclosed sub-volume, and the cover can be removed from the socket in various directions. This is particularly advantageous in narrow shaft structures.
  • the lid can also be attached to the socket in a movable manner, e.g. via an opening mechanism such as a hinge.
  • a “socket” refers in particular to a support element for the closure, which is designed for installation in the shaft structure, particularly in a wall of the partial volume to be separated.
  • the socket defines, in particular, a passage between the partial volume to be separated and the remaining shaft volume.
  • the passage can be rectangular, square, circular, or elliptical, for example.
  • the socket and closure are matched to each other in such a way that the closure can seal a passage defined by the socket in a liquid-tight manner.
  • the socket is preferably constructed as a single piece. This simplifies installation and assembly. However, the socket can also consist of several components, which are then joined together during installation, for example.
  • the socket is designed such that the closure cannot be passed through the socket. This is particularly true regardless of the closure's orientation relative to the socket. This prevents the closure from falling into the partial volume to be separated during maintenance work and, in the worst case, from entering the infrastructure line running therein.
  • the mount is designed as a frame.
  • the frame preferably surrounds the closure, which is preferably in the form of a lid, at least partially, in particular completely, in the region of a lateral surface of the closure and/or in an inner region of the closure when inserted.
