摘要
福州市安泰河西段通湖路至白马河雨水管道工程7#沉井,在施工中突发地面土体塌陷。参建方通过现场施工现状及地质勘查资料,详细分析了其土体塌陷产生的原因,并针对该状况制定了采用小型灌注桩(即树根桩)+高压旋喷桩技术加固方案对该沉井倾斜的一侧地面进行土体加固,然后再进行沉井后续下沉纠偏工作,收到了良好的效果。
From Tonghu Road,which is in the west section of Antai River,to rain pipeline engineering of Baima River——7# open caisson occurred sudden collapse of ground soil in construction. During the construction,based on the site construction status and geological prospecting data,we analyzed the reasons for the collapse of the soil in detail. In view of this situation,we established reinforcing measures of adopting Filling Pile High Pressure Jet Grouting Pile Technology to strengthen the inclined side of the open caisson＇s ground soil. After this,we did the deviation rectification work of the subsequent open caisson sinking. This method had received a good effect.
