用高压喷射注浆法对事故进行处理

Application of High Pressure Jet Grouting Method in Accident Settlement

普贤桥倒虹吸管工程施工中,由于场地地质条件复杂,受到地表水与地下水的渗透影响,沉井顶管施工存在严重施工隐患问题,无法继续施工,通过采用高压喷射注浆法技术措施处理后,沉井顶管施工安全顺利完成,取得成功经验。

In the construction of inverted siphon project of Puxian Bridge, due to the complex geological conditions of the site and being affected by permeation of surface water and ground water, the sinking well and pipe -jacking construction has serious hidden dangers in the construction, which prevent the construction from going on. In such circumstance, after high pressure jet grouting method is adopted to deal with such problem, the sinking well and pipe -jacking construction is completed successfully and safely, which also provides us with successful experience.
