Background
The building deformation joint is a joint for vertically separating a building, which is arranged for avoiding deformation, cracking and building structural damage of the building due to temperature change, different loads born by each part of the building, and different structures and earthquake influence of adjacent parts of the building. When the position of the seam is below the low water level line, water seepage is easy to generate, so that technical treatment is required for the deformation seam, and a water stop belt is poured in a common mode at present.
The steel edge rubber water stop can be classified into a buried steel edge rubber water stop and a back-attached steel edge rubber water stop according to the use condition. Are commonly used in underground construction and post-cast strip construction. The high elasticity of rubber is utilized to generate elastic deformation under various pressure loads, so that the sealing structure is firm and sealed, water leakage of a building structure can be effectively prevented, and the damping and buffering effects are achieved. The embedded steel edge rubber water stop is mainly used for water stop products arranged in concrete such as concrete deformation joints and expansion joints, and has the capability of adapting to the expansion and deformation of the concrete in the elastic and structural modes of rubber materials.
The utility tunnel is a building and accessory facilities built under the city for accommodating two or more city engineering pipelines. Through collecting various engineering pipelines such as the original ground and underground electric power, communication, fuel gas, heat supply, water supply and drainage of the city in an integrated manner and bringing the engineering pipelines into a corridor, the problems of 'aerial cobweb' of the city, reduction of road excavation, avoidance of 'road zippers' and the like can be solved. The system can realize intensive management, reduce operation cost, ensure pipeline safety and release underground space. The cost of repeated road surface repair and the maintenance cost of engineering pipelines are reduced; the integrity of the pavement and the durability of various pipelines are maintained; the contradiction between pipelines and urban greening is reduced, the urban environment is graceful, and the method is an infrastructure construction direction which accords with the national green and sustainable development.
