Background Along with the rapid development of the railway construction industry in China, the standardized requirements of tunnel construction are gradually improved, and meanwhile, the waterproof and drainage construction process of the tunnel is also high in requirements. The tunnel is a buried pipeline formed by casting multiple sections of reinforced concrete structures in a split manner, structural deformation joints are inevitably reserved among the sections, and in order to prevent water leakage at the deformation joints among the sections, a common design and construction mode is to arrange a buried water stop belt in a cast-in-place concrete structure at a telescopic position so as to play a role in preventing water leakage at the deformation joints and the deformation joints during uneven settlement. The Chinese patent publication No. CN102943530B discloses a construction method of a buried ultrathin steel edge rubber water stop fixing device, which comprises a clamping rod, a flange rod and locking reinforcing steel bars, wherein a sealing rod is arranged at the lower end part of the clamping rod. The two flange rods are equal in length, the central lines are coincident, the locking bars are two and positioned on the inner sides of the clamping rods, the clamping rods are perpendicular to the sealing rods and the flange rods, and the two clamping rods and the flange rods are symmetrically arranged along the center of the sealing rods. When concrete is poured, the position of the embedded steel edge rubber water stop is accurately restrained and fixed, the steel edge rubber water stop is not damaged, the position of the steel edge rubber water stop in the concrete is ensured to be accurate, and the water stop effect of the water stop is ensured. The Chinese patent grant publication No. CN110397081B discloses a method for fixing a buried rubber water stop and a reinforcement framework structure, which comprises an outer frame, wherein the outer frame is fixedly connected with an inner frame through a connecting pipe, a supporting frame is sleeved outside the inner frame, and the supporting frame is fixedly connected with the inner frame through the connecting pipe.
