An optimization structure and method for pre-embedded chute of general ring segment based on segment typesetting control

Abstract

The present invention provides an optimized structure and method for a universal ring segment pre-embedded chute based on segment layout control. The general ring segment embedded chute optimization structure based on segment layout control is formed by splicing a plurality of ring segments The ring segment is composed of 6 segments, including 1 capping block, 2 adjacent blocks and 3 standard blocks, the adjacent blocks are respectively arranged on both sides of the capping block, and the standard blocks are arranged in sequence and The standard blocks on both sides are respectively connected with the adjacent blocks; the said capping block, adjacent block or standard block is equipped with or not provided with embedded chute: when the whole capping block or adjacent block or standard block is completely in the ring pipe When the top space or bottom space of the capping block or adjacent block or standard block is not provided with embedded chute. The present invention determines the placement point of each ring segment through the pre-setting of segments in the ring segment, thereby sorting out segment rings with vacant embedded chutes to guide the production of ring segments and reduce the vacancy of embedded chutes Rate.

Description

technical field [0001] The invention belongs to the technical field of rail transit engineering, and in particular relates to an optimized structure and method for a pre-embedded chute of a universal ring segment based on segment typesetting control. Background technique [0002] In addition to passing trains, shield tunnels also need to arrange pipelines, escape routes, fire protection, power lighting and other equipment. These equipment are all hung by installing brackets on the structure wall. The traditional construction technology uses drilling to install equipment supports. In recent years, with the emphasis on structural safety, project schedule control and construction site environment, more and more projects have begun to use pre-embedded chutes to erect equipment supports. [0003] However, the cost of the embedded chute is relatively high, accounting for about 10% of the total price of the segment ring, which increases the project investment. Due to the different...

[0003] However, the cost of the embedded chute is relatively high, accounting for about 10% of the total price of the segment ring, which increases the project investment

Due to the different placement angles of the segments during construction, the pre-buried chute is set in a whole ring, and the pre-buried chute is often vacant in the project, resulting in a waste of engineering quantity
