Construction method for vertical-type hoisting deep-shaft tunnel ballast-soil

Abstract

A construction method for vertical lifting of muck in a deep shaft tunnel. A set of corrugated belt conveyors is arranged in the opening of the deep shaft. The corrugated belt conveyor is composed of a horizontal head, a vertical fuselage and a horizontal tail. The head mainly includes the motor, reducer, driving drum, upper frame and upper idler and undertakes the task of muck unloading; the vertical fuselage mainly includes the anti-spray side plate and the vertical frame and undertakes the task of vertical lifting of muck; the horizontal tail It mainly includes redirecting device, lower frame, buffer roller, tensioning oil cylinder, tensioning roller and lower roller and undertakes the task of muck loading. The invention realizes the vertical lifting of muck, saves the occupied space on the ground, In order to avoid interference with other construction equipment, it can realize continuous and uninterrupted operation, transport a large amount of dregs, high muck transportation efficiency, require a small number of workers, and have low operating costs, which can effectively reduce the construction cost of deep shaft tunnels.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, in particular to a construction method for vertical lifting of dregs in deep shaft tunnels. Background technique [0002] At present, major cities in my country are actively constructing subway transportation networks, and a considerable part of subway tunnels are constructed using the mining method. Due to the narrow space of the tunnel, the large lifting height of the muck, the limited space occupied by the construction, and the limited time of muck transportation, the construction technology of muck removal has become a key factor affecting the efficiency of tunnel construction. [0003] There are two common types of vertical material lifting equipment: bucket chain elevator or gantry crane. The bucket chain hoist can lift the material to a height of tens of meters. It has the advantages of small footprint and compact equipment structure. The disadvantage is that the lifting speed...

Problems solved by technology

The bucket chain hoist can lift the material to a height of tens of meters. It has the advantages of small footprint and compact equipment structure. The disadvantage is that the lifting speed is limited, the efficiency of conveying muck is not high, the key components are easy to wear, and the chain often falls off. bucket phenomenon

The gantry crane needs to be used in conjunction with the grab bucket. It is widely used in the construction of tunnel mucking. Its advantage is that it is suitable for deep shaft construction. The single lifting time of the bucket is long, the construction efficiency is low, and the floor space is large
