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.

Impact drill holes into the pile construction technology is widely used in pile foundation construction job, construction vibrating pile thus to bring the impact of the increasingly prominent on the surrounding environment, the impact of this article on the construction site of a pile of drilled hole pile construction vibration effects on the surrounding environment experiment monitored by the monitoring data analysis found that the peak acceleration increases with distance attenuation occurs quickly, on the basis of analysis of pile foundation construction vibration velocity, frequency, and duration of the impact on the surrounding buildings, it is found that the frequency of vibration velocity with less impact on the housing, the duration of the construction will have an impact. Finally, analysis of the impact acceleration caused by the building structure from the perspective of seismic intensity, vibration intensity was found equivalent vi degree seismic intensity of little effect on the surrounding structures. Furthermore, the greatest impact of vibration on the residential buildings, by the way of excavating vibration attenuation ditch to control effect of vibration is proposed.
