Problems solved by technology

[0004] Aiming at the technical problems in the prior art that when the foundation pit is excavated, the effective excavation depth of the excavator is small, the visual blind spot of the driver of the excavator is large, and the monitoring points on the crown beam are not easy to monitor, the invention provides a subway station The construction method of moving the retaining wall inwards can reduce the process of cleaning the earthwork on the crown beam, facilitate the monitoring of the monitoring points on the crown beam, provide accurate and reliable monitoring data for the excavation of the foundation pit, and can also reduce the excavator. The distance between the excavator and the foundation pit further increases the effective excavation depth of the excavator and reduces the visual blind spot of the excavator driver

Abstract

An embodiment of the present invention provides a construction method for internally moving a retaining wall of a subway station. The method includes: before pouring the crown beam, pre-embedding reinforcement bars for the retaining wall on the side of the crown beam close to the foundation pit; pouring; setting a monitoring point protection device at the monitoring point on the crown beam; and carrying out retaining wall construction. The method provided by the invention can reduce the process of cleaning the earthwork on the crown beam, facilitate the monitoring of the monitoring points on the crown beam, provide accurate and reliable monitoring data for the excavation of the foundation pit, and at the same time reduce the distance between the excavator and the foundation pit. The distance further increases the effective excavation depth of the excavator and reduces the visual blind spot of the excavator driver.

Description

technical field [0001] The invention relates to the field of municipal engineering construction, in particular to an inwardly moving construction method for a retaining wall of a subway station. Background technique [0002] A retaining wall is a structure that can support roadbed fill or hillside soil and prevent the deformation and instability of the fill or soil. The use of retaining walls is currently the most widely used support in road, railway and subway construction projects. Way. [0003] In the prior art, when the strength of the crown beam around the foundation pit reaches the design value, a retaining wall is first built outside the crown beam, and then the excavator enters the site to excavate the foundation pit outside the retaining wall. Since the crown beam is set between the foundation pit and the retaining wall, when the excavator is working, earthwork often falls on the crown beam, which affects the monitoring of the monitoring points on the crown beam an...
