Preparation method of geosynthetic material prestressed reinforced assembly type solidified muck block

Abstract

The invention discloses a preparation method of a geosynthetic material prestressed reinforced assembly type solidified muck block, and the method comprises the following steps: crushing engineering muck, adding water, and performing stirring until the muck is in a flowing state to form a muck raw material; adding water into the muck raw material and the curing agent, performing uniform stirring, performing heating for a period of time, performing cooling, adding the foaming agent, and performing uniform stirring to form light solidified soil; pouring the prepared light solidified soil into a mold provided with a prestress geogrid; after the strength of the solidified soil reaches a preset value, cutting off the redundant geogrids on the two sides. According to the method, rapid recycling of the engineering residue soil is achieved, the prepared geosynthetic material prestressed reinforced assembly type solidified residue soil block has the advantages of being high in strength, small in volume weight, good in bending resistance and the like and can be applied to projects such as roadbed and road surface paving, the preparation method is simple and convenient, the construction period is short, the method solves the problems of low resource utilization rate, high treatment cost, environmental pollution and the like of the muck at present, and has great social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a method for preparing a geosynthetic material prestressed reinforcement and an assembleable solidified dreg block. Background technique [0002] With the continuous expansion of the scale of infrastructure construction in our country, engineering dregs, as a by-product of engineering construction, have become the most important construction waste, which has brought great challenges to the environment. In 2020, the subway shield tunneling alone will generate 225 million m3 of engineering dregs, and the disposal of such a large amount of engineering dregs needs to be solved urgently. The resource utilization of muck is an important way to solve this problem, but at present, the resource utilization rate of muck in my country is extremely low, and the disposal methods of muck are still extensive landfill and stacking, which will cause soil and water pollution. Moreover, ...
