The Engineering Accident Analysis of Cast-In Situ Bored Pile

Abstract:

Abstract: Cast-in situ bored pile is a common form of pile foundation and widely used in road and bridge engineering in China. Because of complex cast-in situ bored pile construction process, high technical content requirement, vulnerable to the impact of human and environmental factors, cast-in situ bored piles prone to various kinds of quality problems in the construction process, such as drilling deflection, drilling hole collapse and diameter reduction, wrong identification of pile-end’s bearing stratum, catheter tube blockage, reinforcement cage floating, pile breaking, pile silted, etc. These problems often make it difficult to meet the design requirements into a pile formation, and difficultly to remedy. In this paper, Zhoutian Zhenjiang bridge at Shaoguan City, Qujiang to Nanxiong highway A03 contract bid package cast-in situ bored pile foundation engineering encountered in the construction collapsed hole, inclined hole, catheter tube blockage and other issues for example to analyzes the cause of cast-in situ bored pile engineering accident, made appropriate preventive measures and processing method.
