Description

Waterproof board for subway construction tunnel

Technical Field

The utility model relates to a subway tunnel construction technical field, specific waterproof board for subway construction tunnel that says so.

Background

The subway is the rapid, large-traffic and electric traction rail transit built in cities. The train runs on a totally closed line, the line located in the central urban area is basically arranged in the underground tunnel, and the line outside the central urban area is generally arranged on a viaduct or the ground. In the process of laying and constructing underground passages such as subway passages or tunnels, waterproof structures are required to be installed on walls to prevent underground water from permeating into the tunnels. The existing waterproof structure generally adopts the steps of firstly paving geotextile on the tunnel wall and then paving and installing a waterproof plate on the surface of the geotextile. However, when the waterproof sheet is used for a long time or the amount of underground water is large, underground water easily seeps out through gaps between the geotextile and the waterproof sheets and gaps between adjacent waterproof sheets, so that the waterproof effect is reduced, and the construction of the subway tunnel is influenced.

Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-2, the waterproof board for a subway construction tunnel of the present invention comprises a waterproof board body 1 and an anchoring rod 5, wherein the waterproof board body 1 is fixedly mounted on the inner wall of the tunnel through the anchoring rod 5, a geotextile 2 is sandwiched between the waterproof board body 1 and the inner wall of the tunnel, and a fixing seat 7 is fixedly mounted at a corner between the lower end of the waterproof board body 1 and the bottom surface of the tunnel; the anchoring rod 5 extends into the side wall of the tunnel, a drain hole 6 is formed in the anchoring rod 5, a plurality of water seepage holes 10 communicated with the drain hole 6 are formed in the top surface of the anchoring rod 5, and a water drainage port communicated with the drain hole 6 is formed in the outer end face of the anchoring rod 5.

One side fixed mounting of waterproof board body 1 has sealed card strip 3, the opposite side be provided with can with sealed card strip 3 sealed joint's sealed draw-in groove 4, when installing waterproof board body 1 along tunnel wall concatenation, through sealed card strip 3 and sealed draw-in groove 4 sealed joint between the adjacent waterproof board body 1 to improve the leakproofness between the 1 seam of adjacent waterproof board body, and then improve waterproof board body 1's water-proof effects.
