Novel formula for reclamation shoal soft soil suitable for ultra soft soil hydraulic reclamation method

Abstract

The invention provides a novel formula for reclamation shoal soft soil suitable for ultra soft soil hydraulic reclamation method. The formula comprises the following components, by mass part: 10 parts of dry soil powder, 2.40 parts of cement, 0.72 part of water glass, 0.576 parts of fly ash, 0.132 part of silicone powder, 0.12 part of gypsum powder, 6.08 parts of water, and 0.072 part of py4 composite admixture. According to a large number of indoor orthogonal experiments by the invention, reinforcement soft soil for hydraulic reclamation and water drainage method in Wenzhou coast, which mainly includes sludge reclamation, is mixed with cement and a plurality of admixtures and compound additives, and pressure resistance, shear resistance and compression performance of the soil can be greatly changed; and compared with s conventional cement formula, the novel formula consumes less supplies, but can greatly improve pressure resistance, shear resistance and compression performance of cement shoal soft soil, especially improve early compressive strength and significantly reduce settlement after construction. Therefore, the formula has important meaning for large area utilization and construction of ultra soft soil hydraulic reclamation coastal reclamation land in coastal southeastern industrial belt.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a new formula suitable for re-reinforcing the foundation of roads and pipelines in seaside reclamation areas by supersoft soil blowing mud blowing method. Background technique [0002] In recent years, tidal flat reclamation work has been vigorously carried out in my country's coastal areas from Tianjin to Zhuhai. For example, Ningbo, Zhoushan, and Wenzhou in the coastal areas of Zhejiang are also carrying out coastal tidal reclamation work. The development of coastal industrial belts has become the key content of coastal local governments. At present, the work of coastal industrial belts in various places is mainly reclamation of tidal flats and land utilization after reclamation. The land generated by tidal reclamation can effectively solve the current shortage of construction land resources in coastal areas, form a new living space for human beings, and create new ...
