Tunnel digging equipment

Abstract

The invention discloses tunnel digging equipment, which comprises a mechanism for keeping soil in a tunnel stable, a digging and crushing mechanism, a supporting mechanism and a conveying mechanism. The mechanism for keeping the soil in the tunnel stable further comprises a movable front edge (1) for preventing the soil around the vault of the tunnel from caving, a hydraulic movable baffle plate (2) for ensuring the stability of the soil on the upper half section of a tunnel face and a lower cutting ring bevel (3) for ensuring the stability of the soil on the lower half end face of a dug face; the supporting mechanism is arranged on the upper part of an equipment supporting ring beam (9), the front end of the supporting mechanism is connected with the movable front edge, the movable front edge is movably hinged with the hydraulic movable baffle plate, the digging and crushing mechanism is connected to a support frame (409) of the equipment supporting ring beam through a swinging seat (10), the conveying mechanism is obliquely arranged on the lower part of the support frame of the equipment supporting ring beam, and one end of the conveying mechanism positioned in the tunnel is provided with a lower cutting ring bevel; and the equipment can safely and efficiently carry out digging and lining operation of the tunnel in a tunnel shield.

Description

technical field [0001] The invention relates to tunneling equipment. Background technique [0002] Shield tunnel boring machine, referred to as shield machine, is a kind of special engineering machinery for tunnel boring. Modern shield tunnel boring machine integrates light, mechanics, electricity, hydraulics, sensing and information technology. It has the functions of excavating and cutting soil, It has the functions of conveying soil muck, assembling tunnel lining, measuring guidance and rectifying deviations, involving geology, civil engineering, machinery, mechanics, hydraulics, electricity, control, measurement and other disciplines and technologies, and has been widely used in subways, railways, highways, municipal administration, hydropower, etc. tunnel Engineering. The shield machine is a closed cylindrical steel assembly with a cutter head at the front end, which excavates the soil while pushing forward along the tunnel axis. There is a closed partition between th...

AI Technical Summary

Problems solved by technology

There is a closed partition between the excavation surface of the existing structure and the inner storehouse branch, and the condition of the entire tunnel surface cannot be directly seen. The construction is invisible, and the construction situation ahead cannot be observed. If an accident occurs, it cannot be detected

When the excavation soil layer is dense and contains a lot of boulders, it cannot be handled, which makes the tunnel construction have great limitations.
