Definitions

  • the invention relates to a method and a device for the subsequent production or renewal of vertical seals on structures below ground against earth moisture.
  • the invention is applicable to all structures of residential, social and industrial buildings, monuments, etc.
  • buildings are fundamentally protected against moisture, among other things. to protect with vertical seals.
  • the subsequent vertical moisture protection of a building is mainly practiced after exposing the basic masonry to the base of the foundation, so that a vertical protective layer made of paints, coatings, sheets, foils, mineral sealing materials etc. meets the structural requirements. can be executed.
  • This excavation, especially for the subsequent vertical moisture protection is associated with high technical, technological, manual and economic expenditure.
  • Restrictions can arise due to building-related conditions, such as due to the surface design of the surrounding terrain, density and type of building, underground supply lines, buildings and the like. surrender. If, for the reasons mentioned above, the production of a functional sealing system is dispensed with, this has a considerably negative impact on the further use and the existence of the building.
  • DD-PS 100 991 plastics are pressed onto the previously heated masonry, for which purpose a movable device can be used.
  • DD-PS 252 097 a seal protection for underground structures is protected, which consists of several layers and is inserted between masonry and soil using complex technology.
  • DD-PS 254 042 vertical protection of the basement masonry is achieved by arranging ventilation shafts.
  • frost damage since the cold can penetrate the masonry unhindered.
  • condensation forms, which causes further dampening of the masonry.
  • AT-PS 377 811 describes a process for draining underground parts of buildings without excavation of the ground, in which a liquid or pasty and later hardening grout acts as a moisture-proof protective layer.
  • the grout is pressed through vertical holes in the ground on the outside of the building or through horizontal holes in the basic masonry from the basement into the surrounding soil.
  • the aim of the invention is to create vertical seals against earth moisture below terrain on existing structures without great effort.
  • the seal should be of high quality and durability.
  • the object is achieved by a method according to which one or more wedge-shaped elements are driven one after the other directly on the masonry surface to the base of the foundation by impact or vibration in the ground. These elements are then slightly pushed off the wall with a spreading device known per se, a spindle, a wedge and other pneumatic or hydraulic devices, so that a gap-shaped free space is created between the wall and the ground.
  • a spreading device known per se preferably liquid or plastic, moisture-repellent substances based on bitumen, plastic and mineral. Sheets and foils are also possible.
  • the shape and size of the free space can be optimally designed by establishing a fulcrum, for example in the middle of the wedge-shaped element, by lever action in the direction of the wall and depending on the sealing variant provided.
  • a fulcrum for example in the middle of the wedge-shaped element
  • the wedge-shaped elements are pulled out of the ground by means of known lifting devices.
  • the remaining cavity can additionally be filled with a sealing suspension, so that at the same time effective protection is created for the sealing introduced.
  • a device which consists of a block-like element which is wedge-shaped in profile. Arranged within the lower wedge surface is at least one valve-like section which can be moved out in the vertical direction and which seals off the filling tube located in the upper stop in the block-like element.
  • the valve-like section is locked via a lowering rod running through the filling pipe at the upper edge of the block-like element.
  • the filler tube can be connected at the upper end to a cover plate which rests firmly on the block-like element and is sealed and pressed in by a closure cap located above it.
  • an inflow opening to the filling pipe can be arranged laterally.
  • the detachable section can have inclined side surfaces that run parallel to the cutout from the block-like element.
  • the device according to the invention works as follows: The block-like, wedge-shaped element is driven into the ground on the side of the wall, mostly up to the base of a building. When pulling back the wedge element, sealing material is simultaneously introduced into the free space under pressure. This is achieved by lowering the detachable valve-like section from the block-like element opens the seal of the filling tube and thus an outlet opening is created for the materials to be introduced.
  • the invention has the advantage that high-quality, consistently functional seals are made on building surfaces under terrain without complex excavation work.
  • the production of the vertical seal is achieved with an easy-to-use, inexpensive device.
  • This device With this device, special sealing tasks outside of buildings without excavation can be solved economically, e.g. the manufacture of waterproof screens and aprons in the ground.
  • FIG. 1 the side view of the wedge-shaped element of the method
  • FIG. 2 the isometric view of the device
  • FIG. 3 a section AA from FIG. 2
  • FIG. 4 the detachable, valve-like section in the upper stop
  • Fig. 5 the detachable, valve-like section in the lower stop.
  • the procedure according to the invention according to FIG. 1 is as follows: In sections, 4 pieces 1.50 m long and 0.50 m wide wedge-shaped elements 3 were driven into the soil 4 directly on the outer wall 1 of the building by means of a pneumatic hammer. An upper clearance of approx. Cm is created by means of attached mechanical spindles. After fixing the wedge-shaped elements 3 in the upper area by means of spacers 7, wedges are driven in using a hammer, which increase the lower free space to approximately 2 cm. In A large-scale bitumen-latex mixture is introduced into the resulting cavity due to the bituminous substrate already present. After the consolidation, the wedge elements 3 are pulled out by means of a pulley. Fine sand is then slurried into the remaining cavity.
  • the device according to the invention is constructed as follows according to FIGS. 2 to 6: In the wedge-shaped, block-like element 12 there is a continuous filling tube 8 for liquid sealing material in the vertical direction. In the lower part of the block-like element 12, the filling tube 8 is closed by the valve-like section 9 which can be removed from the element 12.
  • the section 9 has oblique side surfaces in the front view, which run parallel to the section of the element 12. Via the rigid connection to the lowering rod 10, the section 9 is locked at the upper edge of the block-like element 12. This is done by a cover plate 13 located at the upper end of the lowering rod 10, which hangs tightly on the element 12 and thus also prevents the leakage of sealing liquid.
  • a closure cap 14 is arranged over the cover plate 13.
