Construction method for in-situ full-depth stirring and curing of waste mud into roadbed
The invention relates to a construction method for in-situ full-depth stirring and curing of waste slurry into a road roadbed, which comprises the following steps: carrying out in-situ curing treatment on the waste slurry by adopting a spiral float type slurry stirring and curing pile machine, sequentially adding water, cement and a curing material according to a designed mixing ratio, pulping in a stirring barrel, uniformly stirring, and opening a conveying valve, the stirred solidified slurry flows into a material storage tank and is conveyed to a spiral float type slurry stirring and solidifying pile machine through a conveying pump, and a plurality of groups of large-diameter stirring blades are adopted to perform double functions of constant-speed constant-pressure forced stirring and high-pressure rotary spraying stirring, so that a curing agent and the slurry are fully mixed and bonded, and in-situ solidification of the slurry is realized; according to the method, a large amount of slurry outward transportation and disposal and earth-rock replacement and filling are omitted, the pile machine can automatically walk on the surface of the slurry, an additional construction platform does not need to be built, the construction period and the construction quality are effectively guaranteed, and economic benefits and energy-saving and environment-friendly benefits are remarkable.
本发明涉及一种废弃泥浆原位全深度搅拌固化成道路路基的施工方法，废弃泥浆采用螺旋浮筒式泥浆搅拌固化桩机原位固化处理，按照设计配合比依次加入水、水泥、固化材料，在搅拌桶制浆，拌合均匀后开启输送阀门，将搅拌好的固化浆液流入存料罐，通过输送泵输送至螺旋浮筒式泥浆搅拌固化桩机，并采用多组大直径搅拌叶片进行恒速恒压强制式搅拌和高压旋喷搅拌的双重作用，四搅四喷，使固化剂与泥浆充分混合粘结，实现泥浆的原位固结；本发明免去大量的泥浆外运处置和土石方换填，桩机可在泥浆表面自行行走，不需要搭建额外的施工平台，有效保证了施工工期和施工质量，经济效益和节能环保效益显著。
