Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] As shown in the accompanying drawings, the receiving method of the subway station entrance and exit passage in the construction operation of the rectangular pipe jacking machine of the present invention comprises the following steps:

[0023] (1) Excavating, supporting and pouring the starting shaft 2 at the entrance side of the set subway entrance and exit channel 1;

[0024] (2) The rectangular pipe jacking machine enters the entrance of the subway entrance and exit passage 1 from the starting shaft 2, and then jacks from the entrance along the set subway entrance and exit passage 1, laying rectangular segments until the rectangular pipe jacking machine jacks To the outer edge of the side wall 4 of the station 3 in operation;

[0025] (3) Remove the rectangular pipe jacking machine, transport the internal components of the rectangul...

Abstract

The invention discloses a method for receiving an entrance and exit channel of a subway station during the construction and operation of a rectangular pipe jacking machine. (3) Remove the rectangular pipe jacking machine, transport the internal components back to the departure shaft and lift them out, and leave the shell in place; ( 4) Use cement slurry to seal the gap between the outside of the shell and the soil, and pour concrete on the inside of the shell to be flush with the adjacent segments; (5) Set up temporary fences at the positions corresponding to the entrances and exits of the stations in operation; (6) Remove the station For the part where the side wall connects with the entrance and exit passage, the temporary enclosure shall be removed to complete the construction of the entrance and exit passage. This method completes the construction without affecting the ground traffic.

Description

technical field [0001] The invention belongs to the technical field of construction of a rectangular pipe jacking machine, and in particular relates to a receiving method suitable for construction of an entrance and exit channel by a rectangular pipe jacking machine in an operating subway station. Background technique [0002] In recent years, urban rail transit represented by subway has developed rapidly in my country. Due to the constraints of the surrounding environment, especially the impact of traffic diversion at busy intersections and the relocation of underground pipelines, the roadside stations of subway lines under construction and planning account for about 20%-25% of the total number of stations. The traditional "open belly" method of subway entrance and exit passageway construction requires a large amount of pipeline relocation, difficult pipeline protection, and the need to interrupt ground traffic. [0003] The Chinese patent with the application number 20181...
