| 摘 要： | 定向钻穿越工程通常采用压密注浆法处理地基.本文提出一种新型压密注浆施工方法,利用定向钻同时回拖注浆管与套管,在行进过程中实现注浆管在套管表面上的缠绕,最终进行压力灌浆施工.相比传统施工方法,该法具有成本低、效率高的特点.

| Abstract: | In the crossing engineering by directional drilling,the foundation is usually treated by compaction grouting.This paper proposes a new construction method in compaction grouting.The directional drill is used to pull back the grouting pipe and the casing at the same time and realize the winding of the grouting pipe on the casing surface during the march,and finally the pressure grouting construction is carried out.Compared with the traditional construction method,this method has the characteristics of low cost and high efficiency. |
