Background
In general waterproof design, in order to ensure the waterproof effect of a tunnel, a medium-buried water stop and an external rubber water stop are arranged at structural joints (construction joints, deformation joints and settlement joints) of the tunnel during lining construction of the tunnel. The purpose of the water stop belt is to prevent water leakage at the joint. However, in practical engineering, leakage water is often gathered near the structural joint due to the breakage of the waterproof board, and water is preferably bypassed around the water stop belt which is not installed in place along with the increase of the water pressure of the leakage water, so that the leakage water disease is generated at the joint of the tunnel. The construction and installation method of the buried water stop belt is a difficult problem in the engineering field, and the current common method is as follows: for the reinforced concrete lining, when a formwork is erected, the buried water stop is clamped and fixed by welding two steel bars on a secondary lining steel bar in the tunnel; however, for plain concrete lining, only end steel bars are additionally added to fix the waterstop clamp and the waterstop, and the method is relatively uneconomical. Although the method can fix the buried water stop, the fixing force points of the water stop are few, when the water stop is subjected to irregular and uneven force of flowing concrete during pouring of the concrete, the water stop is loosened or runs out of a mold, the water stop cannot achieve the installation and water stop effects required by the design, and the water stop is prone to damage in the later stage.
