Earth pressure balance rectangular joint shield equipment and construction method

Abstract

The invention discloses soil pressure balance rectangular opening-jointing shield machine. The soil pressure balance rectangular opening-jointing shield machine comprises a cutting system (1), and further comprises a driving system (2), a shield body system (6), a residue discharging system (7), a pipe piece assembling trolley (8), a pipe piece rotating device (9), a pipe piece transporting trolley, a lifting type equipment bridge (10) and a trailer (11), the cutting system (1) and the driving system (2) are mounted on the shield body system (6), the cutting system (1) is located at the front end of the shield body system (6), the driving system (2) drives the cutting system (1) to run, and mud residue cut by the cutting system (1) is discharged through the residue discharging system (7). According to the soil pressure balance rectangular opening-jointing shield machine, excavation of a rectangular section working condition with a large length-width ratio can be achieved, and long-distance transportation of residue soil in a tunnel can be achieved at the same time; and the pipe piece transporting trolley, the pipe piece rotating device, the pipe piece assembling trolley, the lifting type equipment bridge and a tail shield moving pedal work together and cooperatively, and assembling of upper and lower pipe pieces is completed under the condition without pipeline dismantling.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to an earth pressure balance rectangular joint shield and a construction method. Background technique [0002] The comprehensive pipe gallery is one of the important symbols of the modernization of new urban municipal infrastructure construction in the 21st century; the construction of the underground comprehensive pipe gallery has outstanding advantages such as saving land resources, reducing urban road excavation, prolonging the life of municipal pipelines, and improving urban disaster prevention capabilities. , will realize the unified planning, unified construction, and unified management of municipal public pipelines along the road, achieve comprehensive development and utilization of urban road underground space, and avoid "road zippers" on urban roads, which is of great significance for improving regional public infrastructure and serving the ...
