Abstract
The utility model discloses a tunnel waterproof structure which comprises a basement layer arranged on tunnel surrounding rocks, wherein at least two layers of waterproof boards are paved on the exterior of the basement layer in an intersecting and stacked mode, and the waterproof boards are fixedly connected with the basement layer through fastening nails. According to the tunnel waterproof structure, at least two layers of waterproof boards are paved on the basement layer arranged on tunnel surrounding rocks, after the pavement is finished, the intersecting and stacking of the waterproof boards are used to enable gaps among the waterproof boards in the same layer to be sealed, and waterproof effects of a tunnel are improved through the layer-upon-layer waterproof structure. The tunnel waterproof structure can be extensively used as a waterproof structure for tunnels.
Description
Technical field
The utility model relates to a kind of waterproof construction of building engineering field, particularly a kind of tunnel water proofing structure.
Background technology
In constructing tunnel, very strict to the waterproof requirement in tunnel.Yet general only to one deck waterproof construction is set on the tunnel surrounding in the existing tunnel water proofing structure, at work progress, be easy to occur the waterproof construction fracture phenomena, affect construction speed and construction quality, serious words seep water, the tunnel can occur and subside, jeopardize constructor's life security and property safety, so now need a kind of tunnel water proofing structure of good water-proof effect.
The utility model content
The purpose of this utility model is to provide a kind of tunnel water proofing structure.
The solution that the utility model solves its technical problem is: a kind of tunnel water proofing structure, comprise the basic unit that is located on the tunnel surrounding, lay at least 2 layers splash guard in base layer exterior surface, described splash guard intersecting is laid, and is connected and fixed by staple between described splash guard and basic unit.
As further improvement in the technical proposal, described splash guard surface coverage has antiseized separation layer, and described splash guard is SBS elastomeric elements or the modified bitumen members such as synthetic rubber, synthetic resin.
As further improvement in the technical proposal, form the waterproof slit between the adjacent splash guard of same layer, be provided with the waterproof staple that adjacent splash guard is connected and fixed in the described waterproof slit, also be provided with sealant in the waterproof slit.
As further improvement in the technical proposal, described sealant is the polysulfide sealant member.
As further improvement in the technical proposal, outermost splash guard external surface also is provided with fireproof jointing sheath.
As further improvement in the technical proposal, the number of plies of described splash guard is 2 layers, 3 layers or 4 layers.
The beneficial effects of the utility model are: the utility model is laid at least 2 layers splash guard by intersecting on the basic unit of tunnel surrounding, so after laying is finished, utilize the splash guard intersecting with the clearance seal between the splash guard of same layer, by waterproof construction layer by layer, improve the waterproof effect in tunnel.
The utility model can be used as the extensive use of tunnel water proofing structure.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is further described.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is longitudinal section of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, describe the application of the utility model waterproof in the tunnel in detail.
With reference to Fig. 1～Fig. 2, a kind of tunnel water proofing structure comprises the basic unit 2 that is located on the tunnel surrounding 1, lays at least 2 layers splash guard 3 at basic unit 2 external surfaces, and described splash guard 3 intersectings are laid, and 2 in described splash guard 3 and basic unit are connected and fixed by staple 6.
Splash guard by at least 2 layers of the layings of intersecting on the basic unit of tunnel tunnel surrounding 1, so after laying is finished, utilize splash guard 3 intersectings with the clearance seal between the splash guard of same layer, by waterproof construction layer by layer, improve the waterproof effect in tunnel.
Be further used as preferred embodiment, described splash guard 3 surface coverage have antiseized separation layer 4, and described splash guard 3 is SBS elastomeric elements, modified synthetic rubber pitch member or synthetic resin modified bitumen member.
Be further used as preferred embodiment, 3 of the adjacent splash guards of same layer form the waterproof slit, are provided with the waterproof staple that adjacent splash guard 3 is connected and fixed in the described waterproof slit, also are provided with sealant 7 in the waterproof slit.
Be further used as preferred embodiment, described sealant 7 is the polysulfide sealant member.
Be further used as preferred embodiment, outermost splash guard external surface also is provided with fireproof jointing sheath 5.
Be further used as preferred embodiment, the number of plies of described splash guard 3 is 2 layers, 3 layers or 4 layers.
Main job practices is as follows:
(1) planeness of the basal plane of arrangement basic unit 2 adopts cement sand plaster to process, and basal plane should satisfy after processing: D/L≤1/20; D is the depth capacity that falls between adjacent two convex surfaces, and L is adjacent two concavo-convex minimum range; Basal plane must not have sharp-pointed burr position, must not have the ridges such as iron pipe, reinforcing bar, iron wire to exist, otherwise should cut from root, then smears into round surface in the cement mortar that cuts position employing 1:2.5 and covers processing, in order to avoid splash guard is punctured;
(2) press designing requirement and splash guard 3 paving directions, lap width unwrapping wire location, and on basic unit's 2 bullets the line of ink marker, splash guard 3 paving directions should be along the long side direction paving, and wall is paving vertically, and the 3 minor face overlapping the slot of adjacent two width of cloth splash guards should be staggered more than the 300mm mutually;
(3) set again the staple 6 of arch wall waterproof special use after the first floor splash guard leans on the self-adhesion reaction to paste, must not be firmly excessive when setting staple 6, in order to avoid destroy splash guard, and also must not be firmly too small, in order to avoid begining to crop up, nail destroys second layer splash guard; Staple 6 is firm, avoids splash guard to come off; When second layer splash guard is laid, roll with cylinder and to make closely knit full the gluing of second layer splash guard and first floor splash guard, it is fixed also need to set staple 6 in its weak area.Setting with fixing splash guard of staple 6 do not glided, and not falling is degree, and seam adopts the waterproof staple to connect and with the sealant sealing, the sealing layer is the polysulfide sealant member between the splash guard;
(4) splash guard 3 lay complete after; one deck fireproof jointing sheath 5 is installed on the surface; the thick C15 pea gravel concreten layer of one deck 50mm is built on splash guard 3 surfaces in the bottom in tunnel; the fireproof jointing sheath of the splash guard 3 that this pea gravel concreten layer is the bottom; cover with steel plate or plank on splash guard 3 surfaces on tunnel-side, and namely steel plate or plank are the fireproof jointing sheath of the splash guard 3 on the tunnel-side.
More than be that preferred embodiments of the present utility model is specified, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the prerequisite of the utility model spirit, the modification that these are equal to or replacement all are included in the application's claim limited range.
