Underground diaphragm wall structure

Abstract

The embodiment of the invention provides an underground diaphragm wall structure. The underground diaphragm wall structure comprises a wall structure formed by pouring concrete to a reinforcement cagemember. The reinforcement cage member comprises a reinforcement cage, a removable mold plate and a removal-free mold plate, wherein the movable mold plate is detachably connected to one side of the reinforcement cage as an inner mold plate for pouring the underground diaphragm wall, and the removal-free mold plate is fixedly connected to the other side of the reinforcement cage as an outer mold plate for pouring the underground diaphragm wall. According to the underground diaphragm wall structure provided by the embodiment of the invention, the removable mold plate and the removal-free mold plate are separately arranged on two sides of the reinforcement cage, so that the problems that the surface quality of the poured wall is poor and the density of the concrete of the wall is non-uniformas the soil stability is poor can be solved, the wall is compactly poured, level and smooth in surface, and meanwhile, a waterproof layer is arranged on the outer side of the underground diaphragm wall, so that the waterproof performance of the underground diaphragm wall is improved obviously.

Description

technical field [0001] The embodiments of the present invention relate to the field of construction engineering, in particular to an underground continuous wall structure. Background technique [0002] In recent years, the scale of urban underground space development has become larger and larger. The construction of subways, high-rise building basements, underground shopping malls, and comprehensive pipe corridors all require deep foundation pit construction. Among them, the underground diaphragm wall can adapt to a variety of geological conditions, has strong adaptability to complex construction environments, has little impact on the environment, has good integrity, high safety, and good impermeability, and is considered to be the best retaining wall in deep foundation pit engineering. One of the soil structures. The underground diaphragm wall as a supporting structure can be combined with the main structural wall. As the outer wall of the basement, earthwork excavation ca...
