Water network zone lime solidified soil test section filling design method

Abstract

The invention relates to a water network zone lime solidified soil test section filling design method. The water network zone lime solidified soil test section filling design method comprises the steps that S1, an ash mixing proportion is designed, specifically, firstly, a corresponding ash mixing amount proportion is designed according to the moisture content of slurry drying soil, ash is mixed twice, quick lime blocks are mixed for the first time, turning over, stirring and material braising are carried out, crushing is carried out for the second time, then ash is mixed for the second time, and mixing and discharging are carried out by adopting a forced mixing machine; S2, paving and rolling are carried out; and S3, maintenance and detection are carried out, specifically, when solidified soil embankment interlayer filling is continuously carried out, extra maintenance is not needed. The water network zone lime solidified soil test section filling design method has the beneficial effects that for the first layer and the second layer of the solidified soil embankment in the water network zone, the processes of pouring unloading, super-layer thickness filling and cement curing agent doping are adopted in a loaded area, and bottom layer roadbed filling can be smoothly carried out; and a paver paving process is adopted at the third layer, so that environmental pollution caused by road mixing and ash mixing is avoided, and the working efficiency, the roadbed flatness and other qualities are remarkably improved.

Description

technical field [0001] The invention relates to a filling process of mud-solidified soil, in particular to a filling design method for a test section of lime-solidified soil in a water network zone. Background technique [0002] In recent years, engineering construction has produced a large amount of waste mud, which needs to occupy a large amount of land resources for fixed-point consumption, and even cause relatively large environmental pollution. With the rapid development of mud solid-liquid separation technology, such as centrifugation, filter press, etc., the moisture content of mud dregs (mud dried soil) after separation can be reduced to about 35%, which provides the possibility for the utilization of dregs. At the same time, the slag, which is a traditional roadbed filler in Zhejiang Province, is increasingly in short supply due to the government's restrictions on quarrying, and the gap in high-quality materials required for roadbed filling in various places is incr...

Problems solved by technology

[0003] The purpose of the present invention is to propose a method for filling the test section of the lime-solidified soil in the water network zone in order to solve the problems of difficult construction of the road base layer and poor water stability in the existing lime soil filling technology in the water network zone. Construction, to obtain the construction parameters such as the amount of lime cement curing agent for the soft subgrade subgrade in the water network zone, the one-time filling thickness of the bottom layer and embankment partition, the paving process, the combination of road rollers, and the number of rolling times, so as to meet the rapid construction method and provide a solid foundation for the solidified soil Lay the foundation for popularization
