Description

UHPC board disassembly-free cast-in-place concrete municipal pipe gallery system Technical Field The utility model belongs to the field of municipal pipe gallery construction, and particularly relates to a UHPC board demolding-free cast-in-place concrete municipal pipe gallery system. Background The municipal pipe gallery is taken as an important component of urban infrastructure, the construction scale of the municipal pipe gallery is continuously enlarged, the cast-in-situ method is a traditional municipal pipe gallery construction method, but because the cast-in-situ method has long construction period, large field wet workload and obvious influence of weather and underground water, the longer road excavation time can also influence traffic and resident life, the municipal pipe gallery is constructed in a prefabricated assembly mode at present, the field wet workload of the prefabricated assembly municipal pipe gallery is reduced, but the problems of large field assembly difficulty, more assembly joints, easy leakage and poor waterproof performance exist. Disclosure of Invention The invention aims to overcome the defects of the background technology and provide a UHPC board demolding-free cast-in-place concrete municipal pipe gallery system. The invention is realized by the following technical scheme: A UHPC plate dismantling-free cast-in-place concrete municipal pipe gallery system comprises an outer mold and an inner mold, wherein a steel reinforcement framework is arranged between the outer mold and the inner mold, the outer mold is a U-shaped shell manufactured by ultra-high performance concrete prefabrication, the inner mold is a rectangular shell manufactured by ultra-high performance concrete prefabrication, edge chamfers are arranged at four corners of the inner mold, a waterproof coating layer is coated on the outer surface of the inner mold, a plurality of top supports are integrally prefabricated upwards on the top surface of the inner mold and used for supporting the steel reinforcement framework, a plurality of holes are formed in the bottom surface of the inner mold, nuts are downwards fixed on the bottom surface of the holes, the nuts are downwards connected with set screws in a threaded mode, and the set screws downwards penetrate through the steel reinforcement framework to be in contact with the outer mold.
