Definitions

  • the invention relates to a storage vault for liquids with a vaulted ceiling consisting of plastic as well as with at least one existing plastic end wall, which connects the end face of the vaulted wall and is connected to the vaulted ceiling.
  • Such a storage vault is from the EP 1 285 140 B1 known.
  • the well-known storage vault is used for water management in urban areas in bad weather.
  • the storage vault comprises a vaulted casing which, for rigidity reasons, has an elliptical section-shaped cross-section. At the front, the vaulted ceiling is closed by a respective end wall, in which a passage for a pipe connection can be incorporated.
  • the vaulted jacket is provided on the bottom side with support and connection profiles, wherein the support and connection profiles are provided on opposite longitudinal sides of the arched jacket.
  • the object of the invention is to provide a storage vault of the type mentioned, which achieves at least the same stiffness values as the prior art with low use of plastic material.
  • the vault shell of two welded together and closed cavities forming plastic shells is constructed as a twinsheet unit and that the at least one end wall is designed as a separate plastic part, the tool-free by plug profiling with the twinsheet unit is connectable. Due to the design of the vault shell as a twinsheet unit made of two plastic shells welded together, the individual plastic shells can be designed much thinner than the known from the prior art, single-layer storage vault. The significantly reduced wall thickness enables a 25-30% material saving for the plastic with at least constant rigidity. Suitable materials are in particular polypropylene (PP), polyethylene (PE), high density polyethylene (HDPE) and high molecular weight polyethylene (HMPE).
  • PP polypropylene
  • PE polyethylene
  • HDPE high density polyethylene
  • HMPE high molecular weight polyethylene
  • the separate production of at least one end wall allows for a simplified production of vaulted casing and end wall, on the other hand, a simplified transport from the warehouse to the construction site is made possible for the storage vault, since end walls and vault material are stackable independently.
  • mutually complementary plug profilings on the at least one end wall on the one hand and on corresponding end edges of the arch shell on the other hand a secure connection between vault shell and end wall can be achieved without additional fasteners or tools are needed.
  • the storage vault invention is positioned at the site on a prepared drainage and then covered with soil. Preferably connect to the storage vault corresponding sewer pipes, which direct the occurring during a storm water masses in the storage vault. There, the water can gradually seep through the drainage into the ground and into the groundwater, or controlled into the sewage network be initiated.
  • the vaulted casing is provided in the region of a crest line with a hinge arrangement extending over an entire length of the vaulted casing. This makes it possible to fold or fold the vault shell for transport into a transport position, whereby a significantly reduced transport volume can be achieved. This is advantageous for transportation on appropriate transport vehicles such as trucks or the like.
  • the corresponding vaulted ceiling can be set up again in a simple manner and fixed in the functional position.
  • the hinge assembly is formed by a integrally formed on the twinsheet unit film hinge.
  • the end wall is designed as a twinsheet part of two deep-drawn and welded together to form closed cavities plastic shells.
  • the end wall has a high rigidity with low material usage.
  • the closed cavities of the arch jacket are designed as extending over an entire shell circumference stiffening channels.
  • the curvature of the arch jacket is preferably made semi-cylindrical or semi-cylindrical.
  • At least two stiffening channels intersect one another and openly merge into one another.
  • the intersecting stiffening channels preferably extend mirror-symmetrically to one another over the circumference of the arched jacket. Under the Open overlapping is to be understood that the hollow chambers formed by the stiffening channels in the intersections openly merge into one another.
  • stiffening channels are provided with reinforcements, in particular made of steel.
  • Corresponding reinforcements preferably extend over the entire length of the corresponding stiffening channels. It is possible according to the invention that, in particular, only every second or every third stiffening channel, which extends over the jacket circumference of the arched jacket, is provided with a reinforcement. But it is also possible that all stiffening channels are provided with appropriate reinforcements.
  • At least part of the stiffening channels is filled with a flowable or pourable filling material.
  • a flowable or pourable filling material For introducing the filling material into the stiffening channels, at least one filler neck is preferably provided.
  • Gravel or concrete can preferably be used as filling material. It is possible to assist the introduction of the concrete by a vibrating device.
  • At least one connecting piece for a connection of another component is provided in the end wall.
  • a sewer pipe or a gutter or tunnel element is preferably provided.
  • This connection piece may initially be closed by the plastic material and is cut open if necessary in a simple manner by an operator at the construction site. A corresponding pipe end of a sewer pipe can now be plugged into the neck of the end wall in a simple manner.
  • the storage vaults serve as a buffer for the rainwater, so that even large amounts of water can be temporarily absorbed.
  • the vaulted ceiling is formed by a plurality, in the longitudinal direction of the vault shell contiguous shell segments, which are each provided with plug-in profiles for joining the adjacent shell segments.
  • the vaulted casing in the case of a storage vault of the aforementioned type, provision is also made for the vaulted casing to be designed as a single-shell plastic part with stiffening channels which are open toward an inner side and extend over a jacket circumference, which are closed by welded-on lids.

Rather, only a corresponding cover is welded to achieve correspondingly closed cavities in the region of the inwardly open stiffening channels in the region of the edges of the groove-like profiled stiffening channels, which closes the stiffening channels to the inside of the arched shell.
  • precast concrete elements are inserted into the stiffening channels.
  • the precast concrete elements are adapted to the arched shape of the vaulted ceiling and executed according to arcuate.
  • a precast concrete part extends over the entire length of an associated stiffening channel and is adapted in its outer contours to the corresponding cavity contour of the respective stiffening channel to allow a substantially flush embedding of the respective precast concrete element in the open stiffening channel.
  • After embedding or insertion of the corresponding precast concrete part of the respective lid is welded to the edge regions of the associated stiffening channel, whereby the precast concrete part is securely held in the respective stiffening channel.
  • the precast concrete element can be designed as prefabricated reinforced concrete with correspondingly integrated steel reinforcements.
