Description

Tunnel side wall waterproof and drainage structure Technical Field The utility model relates to the technical field of tunnel waterproofing, in particular to a tunnel side wall waterproof and drainage structure. Background In tunnel engineering, the water-proof and drainage work of the side wall is important. The tunnel is complex in environment and rich in underground water, and if the waterproof and drainage measures are improper, side wall leakage and erosion are easily caused, so that the stability and durability of the tunnel structure are affected. The traditional tunnel side wall waterproof and drainage structure has the problems that longitudinal drainage is not smooth, accumulated water is easy to cause, water pressure is increased, a waterproof layer is damaged, a waterproof plate is not tightly connected with an initial support, falling off is easy to occur, drainage and waterproof effects are greatly affected, and the like. Disclosure of utility model The utility model provides a tunnel side wall waterproof and drainage structure, which is used for solving the defects that in the tunnel side wall waterproof and drainage structure in the prior art, a waterproof plate is not tightly connected with an initial support and is easy to fall off, so that drainage and waterproof effects are greatly influenced, reliable connection between the waterproof plate and the initial support is realized, the stability of the structure is ensured, the waterproof plate is prevented from falling off, and further, the drainage and waterproof effects are ensured. The utility model provides a tunnel side wall waterproof and drainage structure, which comprises: The longitudinal blind pipe is arranged between the primary support and the secondary lining; the waterproof plate is hung on the inner wall of the primary support, and the lower edge of the waterproof plate is reversely wrapped on the longitudinal blind pipe; and the pressing strip is used for pressing the waterproof board on the primary support. In addition, the tunnel side wall waterproof and drainage structure can also have the following additional technical characteristics: In some embodiments of the utility model, further comprising: the annular blind pipes are arranged between the waterproof plates and the primary support; Each annular blind pipe is communicated with the side ditch of the side wall.
