Quarrying box device for slurry-balancing shield machine and construction method of quarrying box device

Abstract

Disclosed are a quarrying box device for a slurry-balancing shield machine and a construction method of the quarrying box device. The quarrying box device comprises a box main body, a slurry feeding pipe, a slurry discharging pipe and a quarrying door. The box main body is of a rectangular three-dimensional structure. A cavity in the box main body is provided with a vertical partition plate, a grid net and an unloading plate group. The vertical partition plate divides the interior of the box main body in the longitudinal direction into a left cavity and a right cavity. A slurry discharging hole is formed in the middle of the vertical partition plate. The grid net is arranged in the slurry discharging hole, located on the upstream face side of the vertical partition plate. The size of the grid net is adapted to the size of the slurry discharging hole. The grid net can be in detachable connection with the vertical partition plate on the periphery of the slurry discharging hole through aconnecting part. The quarrying box device further comprises an auxiliary slurry through pipe. By means of the quarrying box device for the slurry-balancing shield machine, the technical problems thata slurry discharging pump is prone to plugging, a quarry box is low in cleaning efficiency, slag cleaning is difficult, and the concrete position of pipeline plugging is difficult to find in an existing structure system are solved.

Description

technical field [0001] The invention belongs to the technical field of mud-water shield construction, in particular to a mud-water balance shield machine quarry box device and a construction method thereof. Background technique [0002] As the most advanced super-large special equipment for tunneling today, the shield machine is a high-tech construction equipment that realizes excavation, excavation, support, etc., and is widely used in urban rail transit, railways, highways, municipal administration, hydropower, etc. tunnel Engineering. Among them, as an important branch of the shield machine family, mud-water balance shield machine has the advantages of high degree of automation, stable excavation surface, and fast excavation speed. It is more and more widely used in high water pressure, sandy, and In muddy soil and other strata. The construction principle and structure of the slurry shield machine are different from those of the earth pressure balance shield machine. Th...
