Assembly-type cast-in-place concrete structure disassembly-free template pipe gallery

Abstract

The invention provides an assembly-type cast-in-place concrete structure disassembly-free template pipe gallery. The pipe gallery comprises a cast-in-place concrete bottom plate, two prefabricated disassembly-free template system wallboards and a prefabricated disassembly-free floor board; wall anchoring steel bars are reserved on the two sides of the cast-in-place concrete bottom plate; each prefabricated disassembly-free template system wallboard comprises a metal truss and disassembly-free templates arranged on the two sides of the corresponding metal truss; the prefabricated disassembly-free floor board comprises a bottom face disassembly-free template and a steel bar net arranged on the bottom face disassembly-free template; and the two prefabricated disassembly-free template system wallboards are vertically arranged on the two sides of the cast-in-place concrete bottom plate, the prefabricated disassembly-free floor board is arranged at the tops of the two prefabricated disassembly-free template system wallboards, pouring concrete bearing walls are arranged in gaps between disassembly-free templates of the prefabricated disassembly-free template system wallboards, and a pouring concrete top layer is arranged on the prefabricated disassembly-free floor board. The main structure of the pipe gallery is completed in a factory form outside the construction site, assembling iscarried out in the construction site, the construction speed of the pipe gallery is increased, and the construction difficulty is reduced.

Description

technical field [0001] The invention relates to an underground pipe gallery, in particular to an assembled underground pipe gallery. Background technique [0002] The underground comprehensive pipe gallery is a structure and ancillary facilities built underground to accommodate various urban engineering pipelines. [0003] The underground pipe gallery is divided into main line pipe gallery, branch line pipe gallery and cable pipe gallery according to the type. The construction method of the underground pipe gallery depends on the cost and the feasibility of implementation. The main line pipe gallery usually adopts the slotting method and cast-in-place construction method due to its large cross-section, self-heavy weight, and large engineering volume. The slotting method is used for construction, which cannot meet the requirements of pipe jacking. Construction is not possible in rainy days and in winter in northern regions. The construction time is long, and the workload o...

Problems solved by technology

Limited by site conditions, the time period is long, and the impermeability of the concrete produced on site is not as good as that produced in the factory, so local leakage is easy to occur, and construction cracks are prone to appear in the culvert pipe, and the side wall of the culvert body is cracked, etc.

[0004] The on-site box culvert sections are connected by rubber waterstops. The disadvantage is t
