Integrated assembly type pipe gallery based on composite bottom plate and construction method thereof

Abstract

The invention discloses an integrated assembly type pipe gallery based on a composite bottom plate and a construction method thereof. Each unit plate block in the composite bottom plate of the integrated assembly type pipe gallery comprises a laminated portion and a cast-in-place portion which is located on the periphery of the laminated portion, wherein each laminated portion comprises a prefabricated bottom plate which is fixedly connected with a foundation cushion layer, a bottom plate truss and a bottom plate cast-in-place layer, and the peripheral edges of each bottom plate truss horizontally outwards extends to form a steel bar framework of the corresponding cast-in-place portion; a double-layer laminated wallboard comprises an outer prefabricated plate which is located on a water attaining face, an inner prefabricated plate which is located on a water opposite face and a cast-in-place sandwich layer which is located between the outer prefabricated plate and the inner prefabricated plate, the outer prefabricated plates and the inner prefabricated plates are connected through wall truss steel bars, and the bottoms of the wall truss steel bars are connected with the margins ofside edges of the steel bar frameworks of the cast-in-place portions of the composite bottom plate; and the lower end surface of the outer prefabricated plate is tightly attached to the upper surfaceof the foundation cushion layer, and a top plate cast-in-place layer of a laminated top plate and the cast-in-place sandwich layer of the double-layer laminated wallboard are integrally casted. According to the integrated assembly type pipe gallery and the construction method, the construction is convenient, fast and efficient, the construction cost is low, the waterproof effect is good, and the overall performance of the pipe gallery is high.

Description

technical field [0001] The invention relates to an integrated assembled pipe gallery based on a composite floor, in particular to an integrated assembled pipe gallery based on a composite floor and a construction method thereof. Background technique [0002] For the construction of underground pipe corridors, there are currently two construction methods: all cast-in-place and a combination of cast-in-place and prefabrication. The traditional cast-in-place method of the full house formwork support has a long construction period, high cost, and poor economic benefits; and the amount of on-site formwork and steel bar binding is large, time-consuming and labor-intensive, and the waste of materials is serious, and the construction civilization is poor; cast-in-place and Among the construction methods combining prefabrication, the semi-prefabrication construction method using double-layer laminated slabs is more common, which greatly reduces the amount of formwork used, reduces co...
