Foundation pit supporting structure for pipeline in-situ protection and construction method thereof
The invention discloses a foundation pit supporting structure for pipeline in-situ protection and a construction method of the foundation pit supporting structure. The foundation pit supporting structure for pipeline in-situ protection comprises four pipeline supporting pieces arranged in two pairs, a retaining wall and a plurality of advanced grouting guide pipes. The two pairs of pipeline supporting pieces are vertically buried in soil bodies on the two sides of the foundation pit in the first direction respectively, the two pipeline supporting pieces in pairs are located on the two sides of a pipeline respectively, a retaining wall is arranged between the two pipeline supporting pieces in pairs, the top of the retaining wall makes contact with the bottom of the pipeline, and the two sides of the retaining wall are each connected with one pipeline supporting piece; the multiple advanced grouting guide pipes are embedded in the retaining walls at intervals, the first ends of the advanced grouting guide pipes are embedded in the retaining walls, the second ends of the advanced grouting guide pipes are embedded in a soil body located on the outer side of the foundation pit, and the advanced grouting guide pipes are gradually and obliquely arranged downwards from the first ends to the second ends. The problem that the pipeline cannot be moved or changed or the cost of the pipeline is high is solved, accidents of water and sand burst can be avoided to a large extent, and the safety of the foundation pit is guaranteed.
本发明公开了一种管线原位保护的基坑支护结构及其施工方法，管线原位保护的基坑支护结构包括四根呈两对设置的管线支护件、挡墙以及多个超前注浆导管；两对管线支护件分别竖直埋设在基坑沿第一方向的两侧土体内，成对的两个管线支护件分别位于管线的两侧，成对的两个管线支护件之间设有挡墙，挡墙的顶部与管线的底部相接触，挡墙的两侧分别连接一个管线支护件；多个超前注浆导管呈间隔埋设于各挡墙内，超前注浆导管的第一端埋设在挡墙内，超前注浆导管的第二端埋设在位于基坑外侧的土体内，且超前注浆导管从第一端至第二端逐渐向下倾斜设置。解决了管线不能迁改或迁改代价较大的问题，可以较大程度地避免出现涌水涌沙的事故，保证了基坑的安全。
