Filling Design Method of Lime Solidified Soil Test Section in Water Network Zone

Abstract

The invention relates to a filling design method for a lime-solidified soil test section in a water network zone, comprising the steps of: step S1, designing the ash mixing ratio: first, according to the moisture content of the mud-dried soil, performing the corresponding ash mixing ratio design, and dividing Two times of ash mixing, the first time mixing quicklime blocks and then mixing the stew, the second time of ash mixing after the second crushing, and using a forced mixer to mix and discharge the material; step S2, paving and rolling Process; step S3, maintenance and inspection: when the solidified soil embankment interlayer filling is carried out continuously, no additional maintenance is required. The beneficial effects of the present invention are: for the first and second layers of the solidified soil embankment in the water network zone, the process of pouring and unloading materials in the loaded area and super-thick filling and adding cement curing agent can be used to smoothly carry out the bottom roadbed filling ; and start to use paver paving technology on the third floor, which can avoid the environmental pollution caused by road mixing and ash, and significantly improve the quality of work efficiency and roadbed flatness.

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
