Deep tunnel variable-section sedimentation clean-up chamber

Abstract

Provided is a deep tunnel variable-section sedimentation clean-up chamber. The deep tunnel variable-section sedimentation clean-up chamber comprises a deep tunnel wall (1), a deep tunnel cabin (2) and a variable section sedimentation clean-up cabin (3), wherein the outer circumstance of the deep tunnel cabin (2) is provided with the deep tunnel wall (1), and a maintenance driveway is arranged at the bottom of the interior of the deep tunnel cabin (2); one section of the deep tunnel cabin (2) is set as the variable section sedimentation clean-up cabin (3), and an intercepting inclined net (4) is arranged at the tail end, along a water flow, of the variable section sedimentation clean-up cabin (3); the top of the intercepting inclined net (4) is inclined toward the inlet direction of water by 30-60 degrees, and the intercepting inclined net (4) is hung on an intercepting hanging ring (5); the bottom of a variable section sedimentation clean-up bulkhead (13) is provided with a high-lift sewage disposal pump (7), and the high-lift sewage disposal pump (7) is connected with one end of a silt lifting pipe (12). The deep tunnel variable-section sedimentation clean-up cabin has the advantages that passive dredging is turned into active defense, the water flow is decelerated in the variable section sedimentation clean-up cabin, and dirt, sludge and sewage can be effectively separated not only on a precipitation bridge, but also through vast and surounding space; besides, dirt intercepting and sludge sedimentation are facilitated through the arranged intercepting inclined net.

Description

technical field [0001] The invention relates to deep tunnel technology, in particular to a deep tunnel variable cross-section sedimentation cleaning cabin. Background technique [0002] Deep storage tunnels refer to large and extra-large drainage tunnels buried in deep underground spaces (generally referring to spaces with a depth greater than 20m below the ground). Generally, in areas prone to waterlogging, densely populated, complex underground pipelines, and difficult to transform existing drainage systems, deep storage tunnels can be set up. The use of large-scale deep storage tunnels supplemented by source runoff control is to implement the construction requirements of the "sponge city" and reflect the water control strategy that is tailored to water conditions and local conditions. It is also a common practice in foreign countries to improve drainage and waterlogging prevention standards in established areas. [0003] Using deep tunnel engineering to treat sewage avoi...

Problems solved by technology

For the dredging of deep tunnels, there are few corresponding studies at home and abroad, and the existing research on the dredging of drainage pipes is limited to taking various measures after silting occurs
