Application research on construction technology of spin dig cast-in-place pile based on the spin dry homework

摘要

It is applicable to use spin dig cast-in-place concrete piles based on the spin dry homework in soil with good soil orthostatic and no groundwater in the hole. Holes can be finished without slurry-supported measures. It is formed directly with wide application. The construction of pile foundation in LSTJNO.3 of LuoYang to LuanChuan freeway was researched and analyzed in this article. Through the technology research and the common problem analysis, the corresponding methods and treatment measures were putted forward.
