A method of using a cantilever shaft boring machine

Abstract

The invention discloses a cantilever shaft sinking machine which comprises a main frame, an excavating system, a deslagging system, a support system and a hoisting system, wherein the main frame comprises a sinking shell and a fixing mechanism; a cutting edge angle is arranged at the lower end of the sinking shell; the fixing mechanism is mounted in the sinking shell; the excavating system comprises a reversing frame mounted below the fixing mechanism, an excavating device mounted below the reversing frame, and a rotation driving device mounted on the fixing mechanism; the deslagging system and the support system are mounted above the fixing mechanism; the hoisting system is arranged on the ground and hoists the main frame; and after the excavating device finishes excavation of a part of atunnel face each time, the rotation driving device drives the excavating device to rotate by a preset angle, so that the excavating device continues working to finish excavation of a next part of thetunnel face. The cantilever shaft sinking machine reduces the equipment working load, realizes smooth excavation of a vertical shaft with ultra-large diameter and large depth, integrates multiple functions, improves the construction efficiency, and excavates the vertical shaft in a complicated geological environment to realize full cross section tunneling of the vertical shaft.

Description

technical field [0001] The invention relates to the field of excavation equipment, in particular to a method for using a cantilever shaft excavator. Background technique [0002] In recent years, the field of urban underground space has developed rapidly, and the development of horizontal construction equipment such as shield machines has become relatively mature, while the traditional construction method of manual excavation is still mostly used for shaft excavation, with low work efficiency and a generally low degree of mechanization and automation. The safety risk in the construction process is high, and the overall construction cost is high. [0003] Shaft excavation is the construction process of excavating shafts vertically downward from the ground. It is widely used in the field of underground construction, such as shield tunneling, receiving shafts, mining shafts, water conservancy project shafts, tunnel ventilation shafts, underground fortification shafts, and under...

AI Technical Summary

Problems solved by technology

[0004] Shaft excavation equipment has undergone long-term development, but has not achieved a major breakthrough. The existing shaft excavation equipment cannot meet the excavation of super large diameter and large depth shaft caves, and there are problems such as slow excavation speed and low degree of mechanization. The tunnel is driven downward through continuous rotation, and the workload is large. It is necessary to solve the problems of difficulty in shaft excavation, low equipment integration, and limited tunneling depth and diameter in the prior art.
