Embodiment Construction

[0022] The present invention provides a method for removing the continuous wall and the side wall at the junction of the old and new subway stations. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] A method for removing the underground continuous wall and the side wall at the junction of old and new subway stations provided by the present invention comprises the steps of:

[0024] S1. Determine the position of cutting the underground diaphragm wall and side wall at the junction of the old and new subway stations.

[0025] like figure 1 and figure 2 As shown, according to the on-site lofting of the construction drawings, the block unit (block wall), cutting line and cutting section position are ...

Abstract

The invention discloses a method for breaking away a continuous wall and a side all at the joint of new and old metro stations. The method comprises the following steps that A, the positions for cutting the underground continuous wall and the side wall at the joint of the new and old metro stations are determined; B, a hoisting hole and a rope passing hole are drilled; C, a guide pulley and wire sawing equipment are mounted and fixed; D, a diamond rope is mounted, and the diamond rope penetrates through the rope passing hole; E, a hoisting rope penetrates through the hoisting hole; F, an operation system is chained, and a safe guardrail is mounted; G, the walls are cut in sequence; and H, hoisting and smashing are conducted. Through the method, the continuous wall and the side wall of thenewly built metro station and the existing metro station can be broken away safely and efficiently, the construction period can be shortened by utilizing the method to conduct underground engineeringconstruction, the construction noises are reduced effectively, dust is reduced, and the construction safety, the safety of the existing structure, the metro operation and the passenger safety are ensured.

Description

technical field [0001] The invention relates to the field of underground engineering, in particular to a method for removing a continuous wall and a side wall at a junction between a new and an old subway station. Background technique [0002] In the process of subway construction, there will usually be transfers between multiple subway lines. When the new subway station is connected to the existing subway station, it is necessary to remove the underground diaphragm wall and side wall of the connecting part of the station. The traditional construction method is that after the construction of the foundation pit of the new subway station is completed, the underground diaphragm wall and side wall adjacent to the existing station side are manually demolished from top to bottom. The traditional construction method has problems such as difficult construction, long construction period, high cost, and huge impact on the surrounding environment. Therefore, existing construction tec...
