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

Abstract

A mud-water balance shield machine quarry box device and its construction method, wherein the stone box device includes a box main body, a slurry inlet pipe, a slurry discharge pipe and a quarry door; the box main body is a rectangular three-dimensional structure; inside the box main body There are also vertical partitions, grids and discharge plate groups in the cavity; the vertical partitions divide the interior of the box body longitudinally, and divide the box body into left and right cavities; There is a slurry discharge hole in the middle of the plate; the grid is set at the slurry discharge hole of the vertical partition and is located on the side facing the water; the size of the grid is adapted to the size of the slurry discharge hole, and the grid The net is detachably connected to the vertical partition around the slurry discharge hole through the connecting piece; the quarry box device also includes an auxiliary slurry flow pipe. The invention solves the technical problems in the existing structural system that the slurry discharge pump is easily blocked, the cleaning efficiency of the quarry box is low, the slag is difficult to clean, and the specific position of the blocked pipeline is difficult to find.

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...
