Abstract

The invention aims to provide a construction method of a supporting pier for a drainage pipeline of a pipe gallery. The construction method is characterized by comprising the following steps: A. manufacturing a concrete supporting pier, and reserving a connecting structure on the concrete supporting pier; B. arranging a height adjusting device by utilizing the connecting structure, and fixing a steel structure support for fixing the drainage pipeline on the height adjusting device; and C. adjusting the steel structure support to the preset mounting height by utilizing the height adjusting device, and filling and compacting the space between the steel structure support and the concrete supporting pier by adopting non-shrinkage concrete. By adjusting the mounting height between I-shaped steel and a steel structure sliding chute, difficulties caused by multiple supporting pier construction standards and construction errors can be solved, and the safety of the pipeline can be increased.

Description

technical field [0001] The invention relates to the technical field of the buttresses of the drainage pipes of the comprehensive pipe gallery, in particular to a construction method for the pier of the drainage pipe of the comprehensive pipe gallery. Background technique [0002] In the comprehensive pipe gallery that incorporates drainage pipes, the relative position of the drainage pipe and the bottom plate of the pipe gallery is not fixed, and the accuracy of the pier setting is high, and it is difficult to realize the standardized construction of the pier or support. The construction error of the concrete pier is large, and the steel structure supports of different sizes have problems such as embedded parts, processing and fixing accuracy. A variety of pier construction standards and construction errors bring construction difficulties, and may lead to uneven stress on the pipeline, affecting the safe operation of the pipeline. Contents of the invention [0003] The pu...
