Embodiment Construction

[0101] like figure 2 Shown is a method for determining the assembly point of the general ring segment in subway shield construction. The shield machine is used to excavate the tunnel to be constructed along the central axis of the tunnel from back to front. Shield segment assembly construction;

[0102] Before any ring shield segment is assembled and constructed, the segment assembly point of the current ring shield segment is determined first, and the process is as follows:

[0103] Step 1. Determining the optional assembly point: According to the staggered assembly method of the shield segment, and according to the segment assembly point of the previous shield segment, select the current ring shield from 16 assembly points to be selected 5 optional assembly points for structural segments;

[0104] The 16 assembly points to be selected are evenly arranged along the circumferential direction and they are 1 point, 2 points, ..., 16 points from front to back in the clockwise ...

Abstract

The invention discloses a metro shield construction general segment assembling point location determining method. A shield tunneling machine is used for conducting shield tunneling construction on a construction tunnel along a tunnel central axis from back to front. After the shield tunneling construction is completed for one link, shield segment assembling construction is carried out. Before anylink of shield segment assembling construction is performed, first of all, segment assembling point locations of current shield segments are determined. Processes include the following steps that firstly, selectable assembling point locations are determined; secondly, selection influence indexes and weight coefficients of the selection influence indexes are determined, and the three selection influence indexes and the weight coefficients of the three selection influence indexes influencing segment assembling point location selection are determined separately; thirdly, the selectable assemblingpoint locations are selectively evaluated, wherein according to a weight coefficient method, the selection of all the selectable assembling point locations is evaluated separately, and the segment assembling point locations of the current shield segments are determined. The shield general segment assembling point location determining method is simple in step reasonable in design, convenient to achieve, good in using effect and capable of conveniently, fast and precisely determining the assembling point locations of the general segments.

Description

[0001] The patent application of the present invention is a divisional application of the invention patent application with the application date of February 19, 2016, the application number 201610093860.3, and the invention title is "A Method for Determining the Assembly Points of Universal Ring Segments in Metro Shield Construction". technical field [0002] The invention belongs to the technical field of shield tunneling, and in particular relates to a method for determining the assembly point of a general ring segment in subway shield construction. Background technique [0003] The shield segment is the permanent lining structure of the shield tunnel. The quality of the shield segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. A ring of shield segments is called a segment ring. Universal segment means that there is only one type of segment ring, which can be used in both straigh...
