回转钻机钻孔灌注桩一机双头施工技术分析

Analysis of Technical Research on One-machine Double Head Construction of Bored Piles for Rotary Drilling Rig

在沿海地区,由于地质特殊,通常采用泥浆护壁钻孔灌注桩进行施工,阐述钻孔灌注桩一种新型的多牙轮钻头成孔一机双头的施工工艺原理,再对其施工的技术要点进行详细的分析,可为同类工程提供借鉴。

In the coastal area, due to the special geological conditions, mud-boring and cast-in-place bored piles are usually used for construction.In this paper, the author expounds the construction principle of a new bored piles, The construction of the technical points for a detailed analysis can be applied to similar projects.
