Description
Technical Field
The invention belongs to the technical field of rail traffic engineering, and particularly relates to a segment typesetting method for a middle ring with a given point position.
Background
In the prior art, according to a progressive algorithm, the point position of the next ring segment is related to the point position of the previous ring segment, and the point positions of the segment are sequentially calculated according to the shield advancing direction, but in practical application, the given condition of part of the intermediate ring points may occur, so that the existing segment typesetting algorithm is not applicable. In order to meet the requirement of point location in actual construction, actual experience is mostly utilized, namely half-operation and half-operation, so that construction quality of a front section and a rear section is reduced, and fitting errors are increased.
Therefore, it is desirable to provide a segment typesetting method for the intermediate ring with a given point location.

The invention aims to provide a segment typesetting method for an intermediate ring with a given point position, aiming at the defects in the prior art.
For this reason, the above object of the present invention is achieved by the following technical solutions:
a segment typesetting method for an intermediate ring with a given point position is characterized in that: the segment typesetting method for the intermediate ring with the given point position comprises the following steps:

(5) a (A) ofiRing to AjTypesetting between rings can be repeated by repeating steps 2 to 4 and replacing the starting ring by AiEnd ring replacement AjAnd then the typesetting between the middle rings of the given point positions is the same.
Giving a point position: the point location is used for describing the circumferential corner of the shield segment ring and is generally determined by the position of the top sealing block. When the circumferential corner of a certain ring segment is a given value, the ring segment is called as a segment ring with a given point position.
While adopting the technical scheme, the invention can also adopt or combine the following technical scheme:
as a preferred technical scheme of the invention: the error is the geometric distance between the central line of the design line and the actual center of the segment ring, and the overall error is the sum of the error values of all the segment rings.
The invention provides a segment typesetting method for a given point position intermediate ring, which can reduce fitting errors and greatly improve the construction quality in a shield region for segment typesetting in the shield region with the given point position intermediate ring.
