Construction method of building slag brick, dry cement and slurry retaining wall
The invention aims to provide a construction method for protecting walls by adopting building slag bricks, dry cement and slurry in soft plastic and flow plastic stratums, and belongs to the technical field of pile foundations in building construction.The construction method comprises the following steps that after hole collapse, the building slag bricks are thrown and filled in drill holes, a rotary excavating drill bit is used for carrying the dry cement and building slag mixture to be conveyed to collapse parts at the bottoms of the holes, and the dry cement and the building slag mixture are poured into the drill holes; firstly, building slag bricks are dumped and filled at the bottom of a hole in a static pressure mode through the conical barrel drilling bucket, then the conical barrel drilling bucket rotates reversely to extrude and rotationally expand the bricks till the wall of the soft plastic layer collapses the hole, finally, the conical barrel drilling bucket makes contact with the bottom to open a valve, is lifted by 2 meters and rotates forwards to discharge a mixture in the drilling barrel, and the drilling barrel repeatedly ascends and descends and rotates reversely at the collapsed hole position of the bottom of the hole. The building slag bricks and the dry cement filler are expanded and extruded to fill the soft plastic and flow plastic layer hole walls, so that a layer of building slag and cement mixed slurry retaining wall is formed at the hole collapse part. The brick-concrete retaining wall formed by the method can effectively resist lateral pressure of plastic and flow plastic soil layers on hole walls.
本发明的目的在于提供一种针对软塑、流塑地层中采用建渣砖块+干水泥、泥浆护壁的施工方法，属于建筑施工中桩基础技术领域，步骤如下：塌孔后采取钻孔内抛填建渣砖块，利用旋挖钻头携带干水泥、建渣混合料运送至孔底的塌陷部位，先锥筒钻斗在孔底静压抛填的建渣砖块，然后锥筒钻斗反向旋转、将砖块挤压、旋扩至软塑层塌孔孔壁，最后锥筒钻斗触底打开阀门，提升2米，正向旋转将钻筒内的混合料排泄出，钻筒在孔底塌孔部位反复升降、反向旋转，将建渣砖块+干水泥填料扩挤、填充至软塑、流塑层孔壁，使其在塌孔部位形成一层建渣、水泥混合泥浆护壁。本发明形成的砖混护壁后可有效抵抗可塑、流塑性土层对孔壁形成的侧压力。
