多功能喷雾套管拔桩工艺在工程中的应用

Application of Multi-function Spray Cannula Pile Pulling Technology in Engineering

为解决场地内原有旧桩造成新增工程桩无法施工的问题,某工程在场地处理阶段采用多功能喷雾套管拔桩工艺对旧桩进行处理,通过对拔桩过程中的主要步骤进行严格控制,有效消除了拔桩对后续工程桩施工造成的影响,取得了较好的应用效果。

In order to solve the problems that new piles can't construction,multi-function spray cannula pile pulling technology was used. According to the construction steps control,the effect of pile pulling on piles construction was eliminated,good effect was obtained.
