Abstract

The invention relates to the technical field of hydraulic engineering, in particular to a novel cement mixing pile construction method. The novel cement mixing pile construction method is characterized in that before construction, a field is leveled to make a preparation for operation, before the construction is started, test detection is carried out on cement soil mixing piles in different areas,and optimal parameters are obtained through data analysis, thereby determining the parameters of cement soil, and after test, the constriction is started. The construction method comprises the following construction steps of (1) positioning a pile machine; (2) preparing cement paste; (3) premixing and sinking; (4) lifting and spouting; (5) repeatedly mixing; (6) cleaning; and (7) moving the pilemachine. The cement paste is uniformly poured by lifting and spouting at constant speed, and then the repeated mixing is carried out to enhance the construction quality. In the whole process, the drilling precision is higher, the ratio of cement to soil is reasonable, the possibility of reducing project errors is greatly reduced, and the construction progress of a project is improved.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering, in particular to a construction method of a novel cement mixing pile. Background technique [0002] It has been more than 20 years in my country to apply the deep mixing method to deal with weak foundations. In recent years, with the development of the economy, the construction method of deep mixing piles has been applied more and more in expressway, tunnel, municipal facilities and building foundation pit engineering. The existing mixing pile technology generally has the problems of high difficulty in controlling the quality control of the concealed engineering site, and high construction costs. [0003] The cement-soil mixing pile construction method is a construction method widely used in soft soil foundation reinforcement. This method is applicable to a wide range of soil types, including muddy soil, silt and cohesive soil. It has the advantages of low cost, wide application r...
