摘要
开挖软弱地层或含水率高的杂填土层进行人工挖孔桩施工,往往由于地下水干扰及土层强度低而无法开挖或造成塌陷,并威胁到施工人员生命安全。对在多个实际工程项目中成功运用的采用深搅桩护壁的桩孔施工工艺进行了分析,并通过试验建立了工程质量控制及评定标准,初步形成了一整套工艺标准。
To excavate weak ground or miscellaneously-filled soil with high water rate for artificially digging piles is usually interfered by the disturbance of groundwater and low strength of soil, which even threaten the lives of construction staff. We analyze the hole-drilling technology with deep-mixing-pile wall protection which has been applied successfully in many projects, establish the standards for engineering quality control and evaluation, and form basically a complete set of technology standards.
