Technical Field
The utility model belongs to the field of tunnel engineering, and particularly relates to a primary support water seepage drainage device for tunnels.
Background
When the hydropower station diversion tunnel, urban underground engineering, highway, railway tunnel and other engineering are constructed, according to different geological conditions, the vault water seepage protection is needed by adopting waterproof measures, so that the construction of an operation surface is prevented from being influenced by water seepage; in the tunnel engineering excavation construction process, groundwater permeates downwards through the vault, and people wear a raincoat during construction, so that flexible actions of the workers are not facilitated; on the other hand, water flow permeates underground, so that the ground in the area behind the tunnel face is muddy, and personnel and equipment slip easily cause safety accidents; aiming at the problem of water seepage and dripping in tunnel construction, a tunnel primary support water seepage drainage device is required to be designed to solve the problem.
Disclosure of Invention
The utility model aims to solve the technical problems of providing a primary support water seepage drainage device for a tunnel, which solves the problems of water seepage under certain working conditions, easy influence on the operation efficiency and reduction of the construction safety in the tunnel construction in the prior art, and has the characteristics of simple structure, convenient arrangement and capability of effectively avoiding water seepage on the top surface of the tunnel from dripping into a construction area.
In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a tunnel preliminary bracing infiltration drainage device, includes the waterproof board, and waterproof board is connected with tunnel vault face inner wall; the tunnel arch top surface inner wall below the waterproof board is connected with a plurality of reinforcing bars as the support frame, is connected with drainage tank and water drainage tank on the support frame.
Preferably, the waterproof plate comprises a plurality of hot-melt gaskets, and the plurality of hot-melt gaskets are nailed on the inner wall of the arch top surface of the tunnel to form the waterproof plate.
Further, a plurality of hot-melt gaskets are fixed on the inner wall of the vault face of the tunnel through shooting nails.
Preferably, the drainage groove is arranged right below the edge of the lower part of the waterproof plate, and the drainage groove is of a semicircular tubular structure.
Further, the drainage groove adopts a semicircular PVC pipe which is made by cutting a PVC pipe.
Preferably, the drainage tank is a circular tube structure which is obliquely arranged, one end of the drainage tank is in plug-in fit with the drainage tank, and the other end of the drainage tank extends to the drainage ditch.
Further, the drainage groove can incline to a certain gradient to facilitate drainage, and the drainage groove is arranged in an inclined way; the drainage tank is made of a whole PVC round tube.
The beneficial effects of the utility model are as follows:
the device for preventing the vault from infiltrating water provided by the utility model avoids the conditions that the vault seepage affects the construction of an operation surface, accumulated water of a tunnel, muddy water and the like in the construction process, improves the construction environment in the tunnel, saves resources and cost, is simple and practical, is convenient to construct and improves the construction efficiency; the whole structure is simple and easy to use, the reusability is good, water seepage and drainage can be effectively carried out, and dripping to a construction area is avoided.

Detailed Description
As shown in fig. 1-4, a primary support water seepage drainage device for a tunnel comprises a waterproof board 1, wherein the waterproof board 1 is connected with the inner wall of a tunnel arch top surface 5; the tunnel arch top surface 5 inner wall below the waterproof board 1 is connected with a plurality of reinforcing bars as the support frame, is connected with drainage tank 3 and drainage tank 4 on the support frame.
Preferably, the waterproof board 1 comprises a plurality of hot melt gaskets 11, and the plurality of hot melt gaskets 11 are nailed on the inner wall of the tunnel arch top surface 5 to form the waterproof board 1.
Further, a plurality of hot-melt shims 11 are fixed to the inner wall of the tunnel dome 5 by means of nails.
Preferably, the drainage groove 3 is arranged right below the lower edge of the waterproof board 1, and the drainage groove 3 is of a semicircular tubular structure.
Further, the drainage groove 3 adopts a semicircular PVC pipe which is made by cutting a PVC pipe.
Preferably, the drainage tank 4 is of a circular tube structure which is obliquely arranged, one end of the drainage tank 4 is in plug-in fit with the drainage tank 3, and the other end of the drainage tank extends to the drainage ditch.
Further, the drainage groove 3 can incline to a certain gradient to facilitate drainage, and the drainage groove 4 is arranged in an inclined way; the drainage tank 4 is made of a whole PVC round tube.
The working principle of the utility model is as follows:
when the waterproof board is used, a plurality of hot-melt gaskets 11 are fixed on the inner wall of the tunnel arch top surface 5 through a nail gun by using nails to form the required area of the waterproof board 1; then, a row of reinforcing steel bars are arranged below the waterproof board 1 to serve as a supporting frame, and the drainage grooves 3 and the drainage grooves 4 are connected to the supporting frame in a lap joint or binding mode, so that water seepage on the inner wall can be discharged from the rear of the waterproof board to the drainage grooves 3 below.
The foregoing embodiments are merely preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without collision.
