Construction method and formwork structure for structure bottom plate and ground plate of underground pipe gallery

Abstract

The invention relates to a construction method for a structure bottom plate and a ground plate of an underground pipe gallery. The construction method comprises the following steps that bottom plate rebars are bound to the position of the to-be-constructed bottom plate, and a bottom plate mold plate is erected; ground plate mold plates are erected above the bottom plate rebars, and the ground plate mold plates are located on the two sides of the to-be-constructed ground plate; a capping mold plate is laid above the bottom plate rebars, the capping mold plate is located on the outer side of a ground plate pouring space and seals the bottom plate pouring space, and the capping mold plate is fixedly connected with the corresponding ground plate mold plate; concrete is poured into the bottom plate pouring space, and the structure bottom plate is formed; and after the pouring of the concrete of the bottom plate is completed, steel fiber reinforced concrete is poured into the ground plate pouring space from the portion above the concrete of the bottom plate, and the ground plate is formed. According to the construction method, the structure bottom plate and the ground plate are formed ata time, and the problems that the material transportation is difficult, the working plane is narrow, and construction is not facilitated due to insufficient light in the post-construction process ofthe building ground plate are avoided.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a structural bottom plate and a ground plate of an underground utility gallery and a formwork structure thereof. Background technique [0002] At present, the construction of underground comprehensive pipe gallery project is in the ascendant all over the country. For the cast-in-place reinforced concrete comprehensive pipe gallery, a 50mm thick concrete floor is designed on the structural floor as the building ground. We inspected the construction of many pipe galleries and found that the construction of the building ground adopts conventional construction methods. The pipe gallery structure is constructed first, and the 50mm concrete building floor is constructed after the roof of the pipe gallery is completed and the formwork is removed. Due to the narrow interior space of the pipe gallery and the lack of light, and the closed space formed after t...
