Combined cast-in-place and prefabricated pipe gallery structure and its construction method

Abstract

The invention discloses a cast-in-situ and prefabricated combination comprehensive pipe rack structure and a construction method thereof. The comprehensive pipe rack structure comprises a cast-in-situ bottom plate horizontally arranged at the bottom of a pipe rack foundation pit, first cast-in-situ side walls which are arranged on two sides of the cast-in-situ bottom plate and perpendicular to the cast-in-situ bottom plate, a first prefabricated middle partition wall which is arranged between the first cast-in-situ side walls on the two sides and perpendicular to the cast-in-situ bottom plate, a prefabricated middle plate which is erected above the first cast-in-situ side walls on the two sides and parallel to the cast-in-situ bottom plate, second cast-in-situ side walls which are arranged on two sides of the prefabricated middle plate and perpendicular to the prefabricated middle plate, a second prefabricated middle partition wall which is arranged between the second cast-in-situ side walls on the two sides and perpendicular to the prefabricated middle plate and a prefabricated superposed plate which is erected above the second cast-in-situ side walls on the two sides and parallel to the prefabricated middle plate. In a construction process of the cast-in-situ and prefabricated combination comprehensive pipe rack structure, the on-site work amount of templates is small, and the waterproofingness is high; meanwhile, the middle partition wall and the middle plate are of prefabricated structures, and a top plate is of a superposed structure; and the prefabricated superposed plate is used as a template, so that the workload of erection of the template is reduced.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery, and specifically refers to a comprehensive pipe gallery structure combining cast-in-place and prefabrication and a construction method thereof. Background technique [0002] In recent years, with the construction of underground comprehensive pipe corridors in my country, the construction technology of underground pipe corridors is constantly improving. At present, the commonly used construction methods for the main structure of underground pipe gallery mainly include the traditional cast-in-place method, the prefabrication method of the whole ring pipe gallery and the full prefabrication method. [0003] The cast-in-place method is to bind steel bars and formwork on site after excavation of the foundation pit, and then gradually pour concrete from bottom to top to form the final pipe gallery structure. Although the structure of the pipe gallery formed by this method has fewer ...

Problems solved by technology

Although the size of each prefabricated part of this method can be adjusted according to the needs, it is suitable for pipe galleries of different structural sizes, but the structure is divided into many blocks, and the integrity and waterproofness are poor; when the structural size of the pipe gallery changes a lot, the required prefabricated parts There are many types, and the corresponding formwork investment and cost increase
