Problems solved by technology

Especially in the design and construction links, there is a large demand for information. If there is information asymmetry in a certain link and the information is not transmitted in time, it will cause problems in the construction link, which will affect the construction period and project quality.

Embodiment 1

[0058] The present embodiment discloses a method for simulating assembly of wedge-shaped segments in an open-cut subway section, as shown in the following example: figure 1 ,include:

[0059] S100. Calculate the center position of the initial segment, the angle of the rectangular segment on the plane and the slope angle along the longitudinal direction of the tunnel according to the route plan, longitudinal section and wedge segment structure size;

[0060] S200. After the wedge-shaped segment of the previous ring is positioned, the segment of the latter ring will be analyzed and determined in combination with the segment of the previous ring and the centerline of the left and right lines, and the subsequent segment will be positioned.

[0061] Specifically, the median line of a subway interval line is divided into three cases on the plane: straight line, gentle curve and circular curve, all of which can be assembled by wedge-shaped segments. On the longitudinal section, the ...

Abstract

An open-cut subway section assembly type wedge-shaped duct piece simulation assembly method comprises the steps that the center position of an initial duct piece, the angle of a rectangular duct piece on a plane and the slope angle in the longitudinal direction of a tunnel are calculated according to a line planar graph, a longitudinal section graph and the structural size of a wedge-shaped duct piece; and after the front-ring wedge-shaped duct piece is positioned, the rear-ring duct piece is analyzed and determined by combining the front-ring duct piece and the middle line of the left line and the right line, and the subsequent duct pieces are positioned. According to the method, the feasibility of segment assembly, the positions, the directions and the like of the segments can be determined, and on-site construction can be guided.

Description

technical field [0001] The invention relates to the field of cut-and-cover subway sections, in particular to a simulated assembly method of an assembled wedge-shaped segment in a cut-and-cover subway section. Background technique [0002] In the process of construction, the prefabricated structure involves multiple links such as design, production, transportation and assembly. It has significant integration and systematic characteristics, and an integrated construction method must be adopted. Especially in the design and construction links, there is a lot of demand for information. If there is information asymmetry in a certain link and the information is not transmitted in time, it will lead to problems in the construction link, thereby affecting the construction period and project quality. In order to solve the above problems and improve the collaborative work efficiency of all parties involved in the construction of prefabricated structures, in the design and construction...
