Soil stabilizer for roadbed filling

Abstract

The invention discloses a soil stabilizer for roadbed filling, which is characterized in that three industrial wastes of granulated blast furnace slag, fly ash and carbide slag are used as raw materials, and Taizhou mucky soil with the water content not less than 50% and the organic matter content not less than 3% is subjected to reinforcement treatment, so that the strength and stability requirements of roadbed filling are met. The invention discloses a construction method for solidifying mucky soil with the soil stabilizer. According to the soil stabilizerdisclosed by the invention, three industrial wastes are combined together according to a proper proportion, and the strength and stability of the soil stabilizer are exerted through a pozzolanic reaction. The soil stabilizer not only can solve the problem that a large amount of mucky soil in Taizhou has no place to stack, but also can solve the problem that industrial waste polluting soil, air and water cannot be directly utilized in industrial production, and meanwhile, roadbed earthwork is saved.

Description

technical field [0001] The invention relates to a soil curing agent used for roadbed filling and belongs to the technical field of building materials. Background technique [0002] In my country's coastal areas and areas along rivers, rivers, and lakes, after a long and complicated geological evolution, muddy soil is widely distributed. These silty soils come from the land reclamation project on the one hand, and undeveloped tidal flat resources on the other hand. The main characteristics of muddy soil are three highs and two lows, that is, high water content, high void ratio, high compressibility, low strength and low permeability. The void ratio is generally between 1 and 1.5, and the water content is higher than the liquid limit. It is a kind of clayey soil. River dredging and engineering excavation lead to the accumulation of a large amount of silty soil, which will inevitably cause problems such as environmental pollution, urban space occupation and relatively high tr...

AI Technical Summary

Problems solved by technology

[0006] Aiming at problems such as nowhere to store muddy soil, inability to directly utilize industrial waste, and insufficient roadbed soil strength, the present invention provides a soil curing agent for roadbed filling and a construction method for curing muddy soil. The limited compressive strength test and water stability test have verified that the soil curing agent has better strength and water stability, and has better economy
