Coordinating and controllable soil digging and slant rectifying method in roadway
The invention discloses a coordinating and controllable soil digging and slant rectifying method in a roadway. The method comprises the following steps that (1) vertical shafts are dug in the sides where sedimentation amount is low in a bypassed mode; (2) anchor cable fixation construction is conducted; (3) a stress applying system and a stress measuring system are installed on an anchor cable; (4) the multiple vertical shafts are selected for digging a horizontal roadway; (5) horizontal soil digging operation is conducted in the vertical shafts where the horizontal roadway is not dug yet, and soil digging holes are distributed in a radial model; (6) horizontal soil digging is conducted in the horizontal roadway, and soil digging holes are distributed horizontally; (7) the anchor cable is subjected to graded loading and tensioning through a hydraulic jack, and in this way, slant rectifying is conducted on a building or a structure; (8) before slant rectifying reaches the standard, stress continues to be applied to the anchor cable, or soil digging operation continues to be conducted in the horizontal roadway; and (9) after slant rectifying is finished, the soil digging holes in the vertical shafts, the soil digging holes in the horizontal roadway and the vertical shafts are backfilled. According to the coordinating and controllable soil digging and slant rectifying method in the roadway, the soil digging amount is high, the success rate is high, the soil digging holes are short, an elevator shaft or a sewage disposal pit can not be encountered, and differential settlement is avoided.
