Rapid stone removing device for soil bin of shield tunneling machine and construction method of rapid stone removing device

Abstract

The invention relates to the technical field of shield tunneling machines, in particular to a shield tunneling machine soil bin rapid stone removing device which comprises a gate assembly, the gate assembly comprises a gate body and a driving assembly used for opening and closing a gate, the gate assembly comprises a gate seat and a gate cover plate, and the gate seat and the gate cover plate are each of a rectangular frame structure. A rectangular opening of the gate cover plate is aligned with a rectangular opening of the gate seat, an opening and closing assembly used for the gate seat and the gate cover plate is arranged between the gate seat and the gate cover plate, the opening and closing assembly is installed on a driving assembly, and grooves are formed in the positions, located at the two ends of the rectangular opening, of the outer walls of the two sides, opposite to the gate seat, of the rectangular opening of the gate cover plate. And elastic supporting plates are fixed to the inner walls of the grooves, sealant is fixed to the outer walls of the sides, facing the opening and closing assembly, of the elastic supporting plates, oil channels are formed in the inner walls of the two sides, away from each other, of the two grooves located at the same height, and the service life of the sealant can be prolonged by reducing friction damage.

Description

technical field [0001] The invention relates to the technical field of shield tunneling machines, in particular to a rapid stone removal device for shield tunneling machines and a construction method thereof. Background technique [0002] A shield machine is a tunnel boring machine that uses the shield method. The construction method of the shield is that the tunnel boring machine builds (lays) the "shield" (referring to the supporting segment) of the tunnel at the same time as it is excavating, which is different from the open construction method. Internationally, the generalized shield machine can also be used in rock formations, just different from the open type (non-shield method) tunnel boring machine. In my country, it is customary to call the tunnel boring machine used for soft soil strata (narrow sense) shield machine, and the one used for rock stratum called (narrow sense) TBM. Shield machines are generally classified into hand-digging shield machines according to...

Problems solved by technology

If these stones stay in the soil bin for a long time, it will damage the mixing device in the soil bin, and at the same time, it will cause the screw machine to get stuck and affect the construction progress.

At present, the commonly used stone removal method is manual removal. Faced with high pressure, narrow working environment and high-load work intensity, the manual handling time is too long, and the operation safety hazard is great.

Therefore, there is an urgent need for a quick stone removal method for the shield machine soil silo; at the same time, during the long-term working process of the gate seal ring of the shield machine, due to the long-term extrusion, wear and other factors of the seal ring, the seal lip of the seal ring is likely to be broken. Thus affecting the sealing performance of the gate
