Abstract

The invention discloses a novel stone powder film bag pile mixed grouting material which comprises cement, stone powder, an additive, fly ash and mineral powder and is characterized by comprising the following components in parts by weight: 1 part of cement, 1-6 parts of stone powder, 0-0.15 part of fly ash and 0.1-0.3 part of additive. The novel stone powder film bag pile mixed grouting material has a compressive strength detection value of 29.7-65.5 MPa, an average value of 44.1 MPa and a variable coefficient of 27.8 percent; four groups of elastic moduli of a core sample of a pile body of a film bag pile are detected, detection results refer to a table 5-3, an elastic modulus detection value is 19000-28900 MPa, and an average value is 25525 MPa; the novel stone powder film bag pile mixed grouting material is applied to a Wu'anxi river downstream management project in Shishi City; a film bag pile silt squeezing and solidifying composite technical scheme is adopted, the used stone powder reach 30000 m<3>, and the concrete core pulling strength of the pile body of the film bag pile body meets design requirements.

Description

technical field [0001] The invention relates to the technical field of a novel stone powder film bag pile mixed grouting material and a mixing construction method, in particular to a novel stone powder film bag pile mixed grouting material and a mixing construction method. Background technique [0002] The pressure grouting construction method solves soil consolidation and improves foundation bearing capacity. There are many grouting materials, but not much waste is used, especially the large amount of waste stone powder is even rarer. Nan'an and Jinjiang in Quanzhou City are large-scale stone processing bases in the country. According to incomplete statistics, Quanzhou's stone processing and production of stone powder reaches two million tons per year. After stone cutting and processing, a large amount of waste powder is produced, which is the so-called stone powder. . The reuse of stone powder is a difficult problem, and it also causes the stone powder of the manufacture...
