Description
Technical Field
The utility model relates to a tunnel waterproof equipment technical field especially relates to a tunnel waterproof construction.
Background
In the tunnel construction process, the tunnel is well prevented from being waterproof and drained, the tunnel engineering quality can be ensured, the potential safety hazard of the tunnel is fundamentally eliminated, and the service life of the tunnel is prolonged. At present, the tunnel water prevention is mainly that non-woven fabrics or waterproof boards are directly paved on surrounding rocks and primary supports, the paving difficulty is high, the effect is not ideal, and water leakage or water seepage due to inaccurate water prevention is easily caused. And the waterproof board is double-deck overlap joint about the overlap joint department, then the welding forms, owing to be the overlap joint mode from top to bottom, must have the space between the waterproof board that is located the upper strata and the concrete, leads to forming the water storage point, influences the water-proof effects in tunnel.
SUMMERY OF THE UTILITY MODEL
For overcoming prior art's defect, the utility model provides a tunnel waterproof construction, its aim at solves the poor problem of tunnel water-proof effects.
The technical scheme for solving the technical problem is as follows: the utility model provides a tunnel waterproof construction, is equipped with a plurality of supports including setting up the geotechnological cloth layer on concrete surface, geotechnological cloth layer outside, and the support outside covers there is the waterproof board, and the waterproof board includes bellying and the connecting portion that are located the bellying both sides, and connecting portion tip detachable is connected with the lap joint board, is equipped with the step on the lap joint board, and the step height is half of waterproof board, and the step position is opposite on the lap joint board of both sides.
The utility model discloses simple structure is ingenious, convenient to use, highly the same with the waterproof board height behind the overlap joint board overlap joint for the waterproof board can closely laminate the concrete, guarantees good water-proof effects.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
As can be known from fig. 1 to 5, a tunnel waterproof structure, including setting up geotechnological cloth layer 2 on concrete 1 surface, geotechnological cloth layer 2 outside is equipped with a plurality of supports 3, and the outside cover of support 3 has waterproof board 4, and waterproof board 4 includes the bellying and is located the connecting portion of bellying both sides, and connecting portion tip detachable is connected with overlap joint board 5, is equipped with step 6 on the overlap joint board 5, and step 6 height is half of waterproof board 4, and 6 opposite positions of step on the overlap joint board 5 of both sides.
The bracket 3 is fixed on the concrete 1 through a shooting nail 7.
Connecting portion tip seted up wedge fluting 8, be equipped with the wedge 9 that inserts in the fluting 8 on the lapping plate 5, the outer end size of wedge 9 is greater than inner size, fixed slot 10 has been seted up in the connecting portion outside, be equipped with fixed block 11 in the fixed slot 10, the fixed block 11 bottom is the wedge.
The upper surface of the wedge-shaped block 9 is wedge-shaped.
And a sealing gasket is arranged between the fixed block 11 and the slot 8.
And a water-proof cushion is arranged between the waterproof plate 4 and the lapping plate 5.
When the waterproof plate 4 is paved, the geotextile layer 2 is fixed on the outer surface of the concrete 1, then the bracket 3 and the shooting nail 7 are used for fixing the geotextile layer, then the waterproof plate 4 is welded on the outer part, and the arch structure is formed when the waterproof plate 4 is paved on the outer part of the bracket 3.
When laying waterproof board 4, carry out the overlap joint between adjacent waterproof board 4, 6 opposite positions of step on the lapping plate 5, and step 6 highly be half of panel thickness, make it can be fine carry out the overlap joint, and the thickness after the overlap joint is no longer than original thickness for waterproof board 4 can avoid forming the cavity retaining with geotechnological cloth layer 2 in close contact with.
Should not too tightly or too loose when geotechnological cloth layer 2 lays, too tightly tears easily, and too loose influences the laying of waterproof board 4, and the same surplus that also leaves of laying of waterproof board 4 makes it and geotechnological cloth layer 2 fully to joint and hug closely on concrete 1 surface, avoids too tightly or too loose to lead to forming the deformation of stress point and arousing waterproof board 4.
Because the thickness in the 5 outsides of overlap joint board only has half of normal waterproof board 4 thickness, so when connecting portion are located the tunnel tip and need not carry out the overlap joint, demolish overlap joint board 5 from waterproof board 4's tip, install fixed block 11 in the fixed slot 10 after demolising for waterproof board 4's surface forms seal structure, and the emergence of the phenomenon of leaking is not avoided, sets up sealed the pad between fixed block 11 and waterproof board 4, avoids leaking.
When connecting waterproof board 4 and overlap joint board 5, insert the fluting 8 of waterproof board 4 with the wedge 9 of overlap joint board 5, then use fixed block 11 to fix it, the outer end size of wedge 9 is greater than inner, make can not drop after pegging graft, pack the water-proof pad in the gap between waterproof board 4 and overlap joint board 5, avoid leaking from the gap in, the bottom of fixed block 11 is the wedge, when closely fixing fixed block 11 on waterproof board 4, because the reason of wedge face, make overlap joint board 5 to the direction removal that is close to waterproof board 4, thereby make both connect more closely.
Compared with the prior art, the utility model, following beneficial effect has: set up special overlap joint board at the tip of waterproof board, highly equals with the waterproof board height behind the overlap joint board overlap joint, and the waterproof board can closely laminate with the concrete, and the centre does not keep the space, avoids water to remain, guarantees good water-proof effects.
