When the position of the seam is below the low water level line, water seepage is easy to occur, so that technical treatment needs to be carried out on the deformation seam, and a water stop is poured in a common mode at present.
The steel-edged rubber water stop can be classified into a buried steel-edged rubber water stop and a back-attached steel-edged rubber water stop according to the use condition. It is commonly used in underground structures and post-cast strip construction. It utilizes the high elasticity of rubber to produce elastic deformation under various pressure loads, thus playing a firm sealing role, effectively preventing water leakage and water seepage of the building structure and playing a role in shock absorption and buffering. The medium-buried steel-edged rubber water stop is a water stop product which is mainly used for being arranged in concrete such as a concrete deformation joint, an expansion joint and the like, and has the capability of adapting to the concrete expansion deformation by using the elasticity and the structural form of rubber materials.

The underground space release system can be managed intensively, the operation cost is reduced, the pipeline safety is guaranteed, and the underground space is released. The cost of repeated repair of the road surface and the maintenance cost of the engineering pipeline are reduced; the integrity of the pavement and the durability of various pipelines are maintained; the contradiction between the pipeline and urban greening is reduced, the urban environment is beautified, and the method is an infrastructure construction direction which accords with national green and sustainable development.
When the trapezoidal bellmouth movement joint of underground pipe gallery structure is under construction, if only prop up the template of establishing the movement joint side, not consolidate it in the reservation of steel limit rubber waterstop is pre-buried, the fixed positional deviation of steel limit rubber waterstop is big after the structure shaping to cause later stage to handle repeatedly, the finished product protection is not in place, increase construction cost. Therefore, it is necessary to provide a method for fixing a steel-edged rubber water stop for a deformation joint of an underground pipe gallery structure, so as to at least partially solve the problems in the prior art.
