Soil stabilizer, self-compacting high-flow-state backfill material and construction method of self-compacting high-flow-state backfill material

Abstract

The invention relates to the technical field of civil engineering materials, and particularly discloses a soil stabilizer, a self-compacting high-flow-state backfill material and a construction method of the self-compacting high-flow-state backfill material. The soil stabilizer comprises the following components in parts by weight: 9-11 parts of cement; 0.1 to 0.5 part of silicon dioxide; 0.5 to 2.5 parts of fly ash; 2-6 parts of slag powder; the self-compacting high-flow-state backfill material comprises the following components in parts by weight: 95-105 parts of soil; 5-25 parts of a soil stabilizer; 15 to 45 parts of water; the invention further discloses a construction method for backfilling narrow and special-shaped grooves by using the self-compacting high-flow-state backfilling material. The self-compacting high-flow-state backfill material provided by the invention is high in compressive strength and good in self-compacting performance.

Description

technical field [0001] The application relates to the technical field of civil engineering materials, more specifically, it relates to a soil curing agent, a self-compacting high-fluid backfill material and a construction method thereof. Background technique [0002] In recent years, the cause of accidents caused by the subsidence of building water, pipelines, and household roads is that during the process of engineering infrastructure construction, affected by factors such as backfill conditions and space, foundation trenches and pit foundations cannot be backfilled compactly, resulting in Its compressive strength is poor; at the same time, the pit foundation cannot be backfilled and compacted, which also brings great potential harm to the seismic performance of high-rise buildings. [0003] In order to improve the compactness and compressive strength of backfilling such as foundation trenches and pit foundations, there are two main traditional backfilling techniques; The ...

Problems solved by technology

[0002]In recent years, the accidents caused by the subsidence of buildings, pipes, and access roads are due to the backfilling conditions and space constraints in the process of infrastructure construction. Affected by other factors, foundation trenches and pit foundations cannot be backfilled and compacted, resulting in poor compressive strength; at the same time, pit foundations cannot be backfilled and compacted, which also brings great potential damage to the seismic performance of tall buildings

[0003] In order to improve the compactness and compressive strength of the backfilling of foundation trenches and pit foundations, there are two main traditional backfilling techniques; Compact backfilling, but this process is difficult to construct, the backfilling period is long, and the backfilling quality is difficult to control; the other is to use plain concrete backfilling. Although this method can ensure the backfilling quality of the foundation trench, the cost of plain concrete backfilling is high and the strength is high. Large, it will bring certain difficulties to later repair and maintenance
