冲击成孔灌注桩能穿透各种土层,并可钻入基岩,适用于地层构造复杂、上部荷载较大的工程,且具有桩身长、设备简单、易操作等优点。我公司在宝鸡某工程桩基施工中采用该技术,取得了良好的效果。一、工程地质概况该工程为六跨单层工业厂房,平面尺寸336m×148m。场地的地质构造比较复杂,表层为3.2m 厚强夯后的回填土;接着为0.5m 厚的耕植土;往下为1.3～7.5m 不
The perforated cast-in-place bored pile penetrates various soil layers and can be drilled into the bedrock. It is suitable for the construction of complex strata structure and large upper load, and it has the advantages of long pile length, simple equipment, and easy operation. Our company adopted this technology in the construction of a construction site for Baoji and achieved good results. I. Overview of Engineering Geology The project is a six-span single-story industrial factory with a plane size of 336m×148m. The geological structure of the site is relatively complex. The surface is a backfill soil with a thickness of 3.2m. After that, it is followed by 0.5m thick cultivated soil; it is 1.3-7.5m down.
