Support construction structure and process of fully prefabricated, spliced and superposed comprehensive pipe gallery

Abstract

The invention belongs to the technical field of comprehensive pipe gallery construction, and in particular relates to a support construction structure and process of a fully prefabricated, spliced andsuperposed comprehensive pipe gallery. The support construction structure comprises a prefabricated comprehensive pipe gallery and further comprises prefabricated support piles, a prefabricated external anchor pile and a prefabricated crown beam. Adjacent prefabricated support piles are in bell-and-spigot joint together, the prefabricated support piles and the prefabricated external anchor pile are in bell-and-spigot joint to the prefabricated crown beam, and the prefabricated comprehensive pipe gallery and the prefabricated support pile are connected by a wet process. Construction of prefabricated and spliced structural parts is carried out fully from a foundation pit support in construction of the comprehensive pipe gallery to later main body structure, and the support structure and themain body structure are superposed fully to reduce the thickness of the main body structure, so that the steel amount and the concrete amount of the structural parts are alleviated, the cost is saved, the occupied area for construction is reduced, and the construction period is shortened.

Description

technical field [0001] The invention belongs to the technical field of comprehensive pipe gallery construction, and in particular relates to a fully prefabricated, assembled and laminated comprehensive pipe gallery support construction structure and technology. Background technique [0002] With the comprehensive development of the city, many supporting infrastructures have been transferred from above ground to underground development, and underground pipelines are becoming more and more complex, so the demand for building comprehensive pipe corridors is increasing. How to quickly build a comprehensive pipe gallery in the core area of ​​the city and minimize the construction impact, the key is to reduce the construction area and shorten the construction period, so as to minimize the impact on the surrounding environment, which is also a problem that needs to be solved urgently. [0003] In order to speed up the progress, more and more prefabricated and assembled construction...

AI Technical Summary

Problems solved by technology

However, in the actual construction, not only the construction of the main structure of the comprehensive pipe gallery takes a long time, but also the construction of the supporting structure takes a lot of time. How to further shorten the construction period and reduce the construction occupied area based on the existing construction technology is always thinking and the pursuit of goals
