摘要
随着桩基广泛应用,桩底持力层检测是控制桩基质量的重要手段之一.为了实现空孔状态下钻探取芯,自主设计了一种辅助平台.通过设计、制作和优化,该辅助平台实现了空孔状态桩底岩溶检测.实践结果表明,相对于传统钻探检测技术,该辅助平台的使用极大缩短了检测时间.
With the wide application of pile foundation,the detection of pile bottom bearing layer is one of the important means to control the quality of pile foundation.In order to realize drilling and coring in the state of empty pilehole,an auxiliary platform is designed independently.Through the design,production and optimization,the auxiliary platform realizes the karst detection at the bottom of the pile in the state of empty hole,which greatly shortens the detection time compared with the traditional drilling detection technology.
