小直径长素混凝土桩在防塌孔加固中的应用

The Application of Long Plain Concrete Pile with Small Diameter in the Anti-collapse Reinforcement Construction of Rotary Digging Pile

本文以兰州新区深埋黄土层上的建筑工程为例,结合场地工程地质条件及水文地质条件,介绍了采用小直径长素混凝土桩在旋挖灌注桩施工防塌孔加固中的应用,对类似地层条件的桩基施工提供可借鉴经验。

This paper takes the construction project on deep buried loess soil in Lanzhou New Area as an example, and introduces the application of long plain concrete pile with small diameter in construction of rotary digging pile anti-collapse reinforcement combined with the engineering geology and hydrogeology conditions. The results can be used as a reference for pile foundation construction under similar stratum conditions.
