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.
