超细钻孔压浆桩施工技术的应用

Application of constructional technology of the super slenderness drilled grouting piles

介绍了在水上施工凉亭、曲桥等荷载较小建筑物基础时,采用了直径Φ219 mm的超细钻孔压浆桩。阐述了用质量轻的SH30型工程钻机,只需搭设简易的水上平台,采用价格低廉的污水泵就能钻孔压浆桩的施工。

The Φ219mm,cast-in place bored of subminiature drill hole were used in construction of the pavilions,bridges in the water and other buildings with light load.The practice shows that using SH30-type engineering drilling rig,setting up a simple platform in the water,and a low-cost sewage pump,we can normally construct in the cast-in place bored pile sit.
