Description
Technical field
The utility model relates to technical field of building construction, specifically, being a kind of prefabricated piping lane slot waterproof of superimposed sheet
Structure.
Background technique
With the fast development in city, underground pipe gallery is being promoted in large area throughout the country, due to much integrating
Piping lane is all under existing busy major trunk roads, and in order to reduce the influence to urban transportation, the duration of pipe gallery should be as far as possible
Shortening, the mode that many pipe galleries all take prefabricated piping lane thus carries out.
In underground pipe gallery work progress, if limited using the prefabricated piping lane of superimposed sheet by superimposed sheet own wt,
It generallys use 2 meters or 3 meters of one section of progress is assembled, therefore piping lane side wall and top plate certainly exist many pieces, if these pieces
It handles bad, the waterproof effect of entire piping lane is necessarily directly influenced, if there is a large amount of percolating water phenomenons, to the fortune in piping lane later period
Battalion and maintenance influence very big.
Currently, prefabricated piping lane plate stitch generallys use exterior wall formwork, the then mode of casting concrete, since plate stitch is smaller,
The concrete vibrating quality of plate stitch position is difficult to ensure, will result in concrete leakiness, it is existing that the later period, there are a large amount of percolating waters
As.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of prefabricated piping lane slot waterproof structures of superimposed sheet, avoid out
Existing percolating water phenomenon.
In order to solve the above technical problems, the utility model provides a kind of prefabricated piping lane slot waterproof structure of superimposed sheet, In
Meet water in the plate stitch of side, be successively packed with from the inside to the outside: polyethylene backing strip, rubber water-proof item and the first elastic break-preventing are anti-
Water sand slurry, is filled with the second elastic break-preventing waterproof mortar, in the polyethylene backing strip and institute in the plate stitch of land side
It states between the second elastic break-preventing waterproof mortar filled with concrete.
Further, the rubber water-proof item include: water expandable waterstop substrate and be located at the water-swellable sealing
Reinforcing rib in substrate.
Further, the reinforcing rib can be mobile relative to the water expandable waterstop substrate.
Further, the reinforcing rib is steel wire.
The utility model has the advantages that
The prefabricated piping lane slot waterproof structure of superimposed sheet provided by the utility model, construction is simple are quick and easy for installation；Centainly
The loss that material is reduced in degree, saves Master Cost；Improve the apparent mass of prefabricated piping lane side wall；Improve prefabricated piping lane
Waterproof performance；Scene meets energy conservation and environmental protection requirement without any pollution.
Detailed description of the invention
Fig. 1 is the schematic diagram of the prefabricated piping lane slot waterproof structure of the utility model superimposed sheet；
Fig. 2 is the enlarged drawing of the partial view A in Fig. 1；
Fig. 3 is the B-B cross-sectional view in Fig. 1.
In figure, 1. polyethylene backing strips, 2. rubber water-proof items, 201. water expandable waterstop substrates, 202. reinforce
Muscle, 3. first elastic break-preventing waterproof mortars, 4. second elastic break-preventing waterproof mortars, 5. concrete.
Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
A kind of prefabricated piping lane slot waterproof structure of superimposed sheet, as shown in Fig. 1 ~ 3, in the plate stitch for meeting water side, from the inside to the outside
Successively it is packed with: polyethylene backing strip 1, rubber water-proof item 2 and the first elastic break-preventing waterproof mortar 3, in the plate of land side
The second elastic break-preventing waterproof mortar 4 is filled in seam, in the polyethylene backing strip 1 and the second elastic break-preventing waterproof
Concrete 5 is filled between mortar 4.
In one optional embodiment of the present embodiment, the rubber water-proof item 2 includes: water expandable waterstop substrate 201
With the reinforcing rib 202 being located in the water expandable waterstop substrate 201, reinforcing rib 202 can be steel wire.Because of the rubber
Sealing rod 2 is circumferentially to enclose in plate stitch, and the intensity of enhancing rubber water-proof item 2 can make it easier to pressure and be set in plate stitch.
In the embodiment, to make water expandable waterstop substrate 201 and reinforcing rib 202 combine stronger, reinforcing rib 202
Surface is provided with brass coating, and conglutination reaction layer is provided between brass coating and water expandable waterstop substrate 201.Brass plating
Layer contains copper and zinc, and production method can be with are as follows: with 10 ~ 14A/dm2Current density one layer is electroplated on 202 surface of reinforcing rib
Copper plate, in copper facing layer surface, with 20 ~ 25A/dm2Current density one layer of zinc coat is electroplated, then in 400 ~ 450 DEG C of ring
Thermal diffusion and fusion are carried out under border, form brass coating.Conglutination reaction layer is by the copper and water expandable waterstop in brass coating
Sulfur-crosslinked reaction in substrate 201 and formed, wherein the temperature of cross-linking reaction is 140 ~ 150 DEG C, preferably 145 DEG C.
In one optional embodiment of the present embodiment, the reinforcing rib 202 can the relatively described water expandable waterstop substrate
201 is mobile.In this way, substrate 201 can be extracted out after the pressure of enhancing rubber water-proof item 2 is set in plate stitch.
It is without being limited thereto with novel protection scope.Those skilled in the art are made on the basis of the utility model
Equivalent substitute or transformation, both are within the protection scope of the present invention.The protection scope of the utility model is with claims
Subject to.
