Vertical shaft construction method and tunneling machine

Abstract

The invention discloses a vertical shaft construction method and a tunneling machine, and solves the problems of great difficulty in slag removal and disassembly of a vertical shaft tunneling machinein the prior art. The vertical shaft construction method comprises the following steps: 1, excavating a leading pilot tunnel communicating with a horizontal roadway at a specified position on the ground; 2, excavating an initial shaft along the leading pilot tunnel, and hardening and strengthening the periphery of a wellhead of the initial shaft; 3, hoisting a shaft tunneling machine to the bottomof the initial shaft, and debugging components and systems of the shaft tunneling machine; 4, carrying out expanding excavation on the bottom of the initial shaft along the leading pilot tunnel through a tunneling machine body of the shaft tunneling machine in cooperation with a propelling system, specifically, a conical slope with the leading pilot tunnel as the center is formed on the excavation surface. According to the tunneling machine, the tunneling machine body, a shaft wall supporting system and the supporting shoe propelling system cooperate for use, lining operation on a tunnel wallis carried out while downward expanding excavation and tunneling are carried out, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of shaft construction, in particular to a shaft construction method and a boring machine used therein. Background technique [0002] At present, there are many types of construction methods and roadheaders for shaft excavation, such as shaft expansion excavators, shaft drilling rigs and raise drilling rigs, etc., such as application number 201310589632.1. But for the shaft excavation method of leading pilot tunnel construction, just need to use raise boring machine, shaft expansion excavator such as application number is a kind of large-section shaft excavation machine and its construction method of 201911163689.9. However, the above-mentioned existing technologies need to be comprehensively considered in combination with stratum, slag discharge method, structural design, cost control, excavation diameter, safety, etc., resulting in shaft expansion excavators often with complicated equipment, slag discharge ...
