Retaining-wall reinforcement cage for traversing underground pipelines and construction method thereof

Abstract

The invention discloses a retaining-wall reinforcement cage for traversing underground pipelines and a construction method thereof. The retaining-wall reinforcement cage comprises a reinforcement cageframework, primary suspension point groups and secondary suspension point groups, wherein the secondary suspension point groups are arranged on two sides of one end of the reinforcement cage framework; and the primary suspension point groups are arranged at an end of the reinforcement cage framework between the secondary suspension point groups. The construction method comprises the steps of slotting, suspending movement by use of the primary suspension point groups, suspending movement by use of the secondary suspension point groups and final accomplishment of construction. Owing to variations of positions of suspension points and transverse swinging movement in a slot, the retaining-wall reinforcement cage is prevented from stretching across the underground pipelines. The problem that aretaining wall is difficult to construct in a pipeline dense area can be effectively solved. The retaining-wall reinforcement cage has the advantages that an occupied area is small, a site is easy toarrange, the progress of works is high, interference factors are less and exiting facilities around are guaranteed to be in a perfect condition.

Description

technical field [0001] The invention belongs to the field of underground construction, and in particular relates to a ground-connected-wall reinforcement cage for crossing underground pipelines and a construction method thereof. Background technique [0002] With the continuous development of my country's subway transportation construction, the construction conditions of the subway are subject to more and more restrictions, especially in the construction of subway stations represented in the old urban areas, often encounter very complicated underground pipeline environment, various underground pipelines criss-cross, There are many uncertain factors, difficult detection, many property rights units involved, long relocation time, and difficult coordination, which seriously restrict the construction period of the project. For some high-risk pipelines, it may even cause huge personal and property losses. [0003] The underground pipelines within the construction scope of the grou...
