Integrated trench open cutting heading machine with automatic backfill function

Abstract

An integrated trench open cutting heading machine with the automatic backfill function comprises a drive hydraulic motor, a muck bin, a belt conveyor, a belt digging and cutting system, a connecting rod, a rotation hydraulic motor, an adjusting oil cylinder, a guiding sleeve, a front shield, a hydraulic pump station, a hinge oil cylinder, a hinge ring, a tail shield, a main thrust oil cylinder and a rotation shaft. Shovel teeth are welded to a crawler belt of chain wheels of the belt digging and cutting system. The drive hydraulic motor is connected with the belt digging and cutting system. The belt digging and cutting system and the muck bin are fixed. The muck bin and the front shield are hinged through the connecting rod. The belt conveyor is connected with the muck bin through the rotation shaft. The front shield and the tail shield are connected through the hinge oil cylinder and the hinge ring, a hinge seal is arranged, and the main thrust oil cylinder is connected and fixed to the tail shield through bolts. The integrated trench open cutting heading machine is high in automation degree, the construction efficiency is improved, the pipe gallery construction distance is short, the construction cost is much lower than that of a shield tunneling method, and the integrated trench open cutting heading machine is applied to the technical field of tunnel heading machines.

Description

technical field [0001] The invention relates to a comprehensive pipe ditch excavator with automatic backfill function used in the construction of an underground comprehensive pipe gallery in the technical field of tunnel boring machines. Background technique [0002] At present, the comprehensive pipe corridor project refers to the construction of a municipal shared tunnel under the urban road, which integrates various municipal pipelines such as electricity, communication, water supply, and gas, and implements unified planning, unified construction, and unified management to achieve underground space. Comprehensive utilization and resource sharing. The traditional way of directly burying municipal pipelines not only causes repeated excavation of urban roads, but also wastes urban underground space resources. A comprehensive pipeline corridor is built along the urban road to intensify various pipelines, and comprehensive pipeline corridors are adopted. The laying of various...

AI Technical Summary

Problems solved by technology

[0003] There are many construction methods for comprehensive pipe corridors, but according to different environments, their economic and social benefits vary greatly

Generally speaking, in the newly built urban area, the pipe gallery should be constructed simultaneously. It is economical to use the open-cut method, but the project period is long and the degree of automation is low; in the old urban area, the construction of the pipe gallery should consider the environmental impact and possible demolition costs , the shield method is better than the open cut method, but because the construction of the pipe gallery is different from other tunnel constructions, it is necessary to set nodes every 100 meters or so, which makes the excavation cost of the shield method remain high
