Abstract

Due to the special geographical location, geological conditions and construction conditions of the project in Tibet, there are often problems in the construction of ultra-deep underground diaphragm wall, which lead to the current preparation regulations, cost standards and supporting quotas can not be fully applied. It is necessary to carry out research on the construction efficiency of underground diaphragm wall in Tibet. To provide reference materials for the construction and economic analysis of the ultra-deep underground diaphragm wall in the later hydropower project. This paper takes a project in Xizang Province as the research object, through the analysis of the quota consumption and actual construction consumption of grab bucket and hydraulic slot milling machine, the construction efficiency of groove forming machinery under different formation conditions and groove depth is obtained, the rationality of the extension of the quota depth coefficient is verified, and the construction efficiency of the groove forming equipment is analyzed. It provides certain reference and reference for the construction and investment preparation of ultra-deep underground diaphragm wall in the later period of high altitude area.
