人工挖孔桩在基础工程中的应用

Application of artificial hole pile in foundation work

介绍人工挖孔桩的成孔、护壁、钢筋笼制作和安装、桩芯混凝土浇灌等施工过程。施工后对桩基的检测试验成果表明在特定的地质、地形和水文地质条件下,在较恶劣的环境中,人工挖孔灌注桩是可行的,只要在施工中严格控制各施工工序,该技术不仅能够降低成本,提高经济效益,而且还能缩短工期,提高工程质量。

An introduction is made on the construction process of artificial hole pile including holing, wall protection, fabrication and installation of reinforcing cage, pile core concrete grouting etc. The results of inspection on the completed pile foundation have demonstrated that in adverse Circumstances, the application of artificial hole grouting pile is feasible and will be able to reduce cost, upgrade economic benefit, shorten construction period and improve construction quality under given geological, topographic and hydro-geological conditions and with essential strict control of each construction procedure.
