Problems solved by technology

The nearby disposal of dredged silt will cause environmental problems such as occupation of cultivated land, diffusion of pollutants during stacking, and pollution of rivers and marine environments.
The two methods of dehydration and sintering are only suitable for the treatment of dredged sludge with high water content in small batches, but the cost is high, and the sintering method is not suitable for dredged sludge with high sand content

Abstract

The invention relates to lightweight silt foam composite soil which is characterized by comprising the following components by mass percent: 81% to 85% of raw soil as, 10.5% to 13.5% of cement as a curing agent, 2.5% to 4.5% of gypsum powder or silicon powder and 1% to 3% of lightweight materials. The invention further discloses a preparation method of the lightweight silt foam composite soil. The lightweight silt foam composite soil has the advantages of light weight, high strength, good independence, short construction period, waste recycling and environmental protection. In addition, the lightweight silt foam composite soil can solve the problems of uneven settlement and vehicle bumping at a bridge head, poor stability of a retaining wall, untight pressing of a pipe ditch, slumping of a side slope and the like due to the soil filling on a roadbed. Therefore, the lightweight silt foam composite soil is an ideal civil engineering material and can be widely applied to the construction of transportation, civil engineering and hydraulic engineering.

Description

technical field [0001] The invention relates to a lightweight mixed soil and a preparation method thereof, more specifically relates to a lightweight mixed soil prepared by utilizing silt and foam plastics and a preparation method thereof, and belongs to the technical field of transportation and construction engineering materials. Background technique [0002] my country is currently in a period of rapid economic development. In many large-scale earthwork projects, such as highway construction, reinforcement of river embankments, building filling projects, and marine engineering, a large amount of filling soil is required. At present, these soils are generally obtained through excavation of cultivated land, sand mining in riverbeds, mountain quarrying and other methods, but the soil resources obtained by these methods are limited. Moreover, these methods will also bring about many negative effects, such as causing soil erosion and reducing farmland. Because in our country, ...
