Horizontal opposite soil-digging slant rectification method for indoor shafts of building
The invention discloses a horizontal opposite soil-digging slant rectification method for indoor shafts of a building. The method includes: digging the shafts at the positions, close to a foundation, on one small-settlement side of the indoor building, and pouring concrete guard walls on the wall walls of each shaft; reserving ducts in the concrete guard walls at positions of digging-out-soil holes by means of embedding steel sleeves; constructing horizontal digging-out-soil holes in the shaft bottoms by digging soil towards one direction with a Luoyang shovel along the horizontal direction, wherein the length of a handle of the Luoyang shovel is smaller than the diameter of each shaft due to limitations of working space of the shaft, when digging soil till the handle of the Luoyang shovel is about to sink in the horizontal digging-out-soil holes, connecting with a new Luoyang shovel handle in a screwed manner, and continuing construction or constructing horizontal digging-out-soil holes in opposite directions; after the purpose of slant rectification is realized, subjecting the horizontal digging-out-soil holes to grouting treatment and backfilling and blocking the shafts. For the shafts small in space, a manual soil digging tool extension mode is proposed, the problem of incapability in mechanical drilling is solved, and the method is particularly suitable for building slant rectification in water sensitive soil in which horizontal radiation caves cannot be constructed with a high-pressure water blast method.
