Problems solved by technology

Because shield tunneling is a kind of engineering machinery specially designed for segment specifications, when a shield machine is completed in an area with a segment outer diameter of φ6000mm, it must be transferred to an area with a segment outer diameter of φ6200mm for construction. The transformation plan of the original shield machine needs to remake the cutter head and shield body of the main part of the original shield machine, which will be accompanied by an increase in equipment costs and an extension of the transformation period.

Abstract

The invention relates to a shield tunneling machine suitable for both phi 6000 and phi 6200 pipe pieces and a realization method thereof. The shield tunneling machine comprises a shield body suitable for phi 6000mm pipe pieces and a tail shield suitable for phi 6200mm pipe pieces, an annular steel plate is fixed on the outer side of a knife disc ring, outer diameter of the annular steel plate is uniform with that of a knife disc ring of the shield tunneling machine suitable for the phi 6200mm pipe pieces, a tubular steel plate is fixed on the outer wall of each of a front shield shell and a middle shield shell, and outer diameter of the tubular steel plates is uniform with that of the front shield shell and the middle shield shell of the shield tunneling machine suitable for the phi 6200mm pipe pieces. The realization method includes: taking the annular steel plate and the tubular steel plates down, and changing a tail shield into the tail shield of the shield tunneling machine suitable for the phi 6200mm pipe pieces. On the basis that original structure of the shield tunneling machine is unchanged, a knife disc, a front shield and a middle shield of the shield tunneling machine are modified to enable the shield tunneling machine to be suitable for tunnel construction with pipe pieces in two specifications.

Description

technical field [0001] The invention belongs to the construction technology of subway tunnels, and in particular relates to a main engine of segmental shield tunneling machines of φ6000 and φ6200 and a realization method thereof. Background technique [0002] The development of domestic urbanization requires cities to have fast, environmentally friendly, convenient and comfortable public rail transit. Therefore, my country's subway and light rail construction has entered a stage of comprehensive development, requiring a large number of shield equipment. The problem of how to use the lowest cost-effective supporting equipment to complete the construction of the corresponding geological engineering project arises accordingly. [0003] There are mainly two types of segment types for domestic subway construction, one is that the outer diameter of the segment is φ6000mm, and the other is that the outer diameter of the segment is φ6200mm. Because shield tunneling is a kind of eng...
