Abstract
The invention discloses a belt type hole bottom accumulated slag cleaning device and method based on TBM synchronous lining construction. Technical problems that labor intensity of manual cleaning is high, the cleaning speed is low, and a transport vehicle cannot conduct synchronous lining construction are solved. The device mainly comprises a supporting frame, a first-stage conveying mechanism, a second-stage conveying mechanism and a third-stage conveying mechanism, walking wheels are arranged at the bottom of the supporting frame, a driving motor is arranged, and the first-stage conveying mechanism, the second-stage conveying mechanism and the third-stage conveying mechanism adopt belt conveying and are fixedly arranged on the supporting frame; an air duct at the top of the tunnel and a bracket of a TBM deslagging belt on the side surface are ingeniously avoided through reasonable layout design; the cleaning method is a method for cleaning the accumulated slag at the bottom of the hole by using the device. The method is advantaged in that a problem of procedure interference in the tunnel is solved, synchronous lining construction can be achieved, labor intensity is greatly reduced through belt conveying and matched electric power facilities, and slag removal efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of TBM equipment, in particular to a belt-type tunnel bottom slag cleaning device and method based on TBM synchronous lining construction. Background technique [0002] During the construction of TBM tunnels, due to the poor geological conditions of the surrounding rocks, most of the surrounding rocks are Class IV and Class V. During the excavation process of TBM, a lot of stress is often generated because it is deeply buried in the ground, which makes the surrounding rock broken and unstable. , it will squeeze the rock surface and deform the rock surface due to the force, which will further increase the degree of cavity collapse and the amount of rockfall, resulting in a large amount of slag accumulation at the bottom of the tunnel. At the same time, there will be a small amount of sprayed grout during the support process. A certain amount of muck will also be generated during the bounce-back and cleaning ...
