Embodiment Construction

[0021] Combine below figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The present invention is described further:

[0022] The invention provides a method for transforming the shield propulsion system adapted to 22.5° segments to adapt to 36° segments, and divides the oil cylinder arrangement of propulsion cylinders adapted to 22.5° segments into two axes according to the original 32 oil cylinders evenly distributed. Four quadrants, including the first quadrant, the second quadrant, the third quadrant, and the fourth quadrant, the transformation of the first quadrant includes the following steps: Welding the extension shoe 10 on the original No. 1 shoe 1 of the propulsion cylinder to form a new 1 No. 1 brace shoe 5, new No. 1 shoe plate 11 is installed on the new No. 1 brace shoe 5, so that the propulsion brace shoe can meet the assembling of the capping block at the 18° position deviated from just above.

[0023] Divide the original No. 2...

Abstract

The invention discloses a method for transforming a shield propulsion system adapted to a 22.5° segment to adapt to a 36° segment. The oil cylinder layout of the propulsion oil cylinder adapted to a 22.5° segment that originally adopted 32 oil cylinders evenly distributed is divided into two axes. Four quadrants, transform No. 1, No. 2, No. 3, and No. 4 brace shoes in the first quadrant of the propulsion cylinder to form 5 new sets of brace shoes, and the modification of the symmetrical positions of the other three quadrants is the same as that of the first quadrant, so that In the 10 adjustment positions to 360°, there is a group of oil cylinders corresponding to the position where the 36° segment capping block appears. The invention solves the problem that the shield machine suitable for 22.5° segments cannot be used for 36° segment assembly, shortens the transformation time, shortens the period of shield equipment stopping and waiting due to the interval of project continuation, and enhances the adaptability of the equipment.

Description

technical field [0001] The invention relates to the technical field of tunneling, in particular to a method for transforming a shield propulsion system adapted to a 22.5° segment to adapt to a 36° segment. Background technique [0002] At present, in the construction of domestic subway tunnel shield method, there are two specifications for the indexing of the longitudinal bolts of the preset segments used in tunnels with the same diameter. Among them, Guangzhou, Shenzhen, Xi’an, Nanchang, and Chengdu urban subways use an outer diameter of 6000 mm and an inner diameter of 6000 mm. 5400mm, the longitudinal bolt index is 36° prefabricated segment; Beijing, Zhengzhou, Wuhan, Shenyang urban subways use prefabricated segment with outer diameter 6000mm, inner diameter 5400mm, longitudinal bolt index is 22.5°. Each closed ring of these two segments is composed of 6 segments. In the sequence of assembling the 6 segments into a ring, the segment with beveled angles at both ends become...
