Protection structure and protection method for shallow-buried pipeline penetrating through foundation pit support structure
The protection structure comprises the foundation pit support structure, the foundation pit support structure comprises foundation pit construction method piles, RJP piles and a foundation pit top beam, and the four RJP piles are arranged on the two sides of a foundation pit below the shallow buried pipeline in pairs; the foundation pit top beam is arranged above the foundation pit construction method pile and the RJP pile and below the shallow buried pipeline, a plurality of concrete supporting embedded steel bars are arranged on the inner side wall of the foundation pit top beam and anchored on the inner side of the foundation pit top beam, joints are reserved on the concrete supporting embedded steel bars, an embedded sleeve is arranged on the concrete supporting embedded steel bar joint on one side, and the embedded sleeve is connected with the foundation pit construction method pile and the RJP pile. The embedded sleeve is arranged on the outer side of the connector in a sleeving mode and tightly attached to the inner side face of the foundation pit top beam, the concrete support embedded steel bar connector on the other side is suspended, the bearing protection structure comprises a protection cover and a concrete support, the protection cover is located on the outer side of the shallow buried pipeline, and the concrete support is located below the protection cover and above earthwork in the foundation pit. According to the invention, the relocation construction of the pipeline can be avoided, and the construction cost is reduced.
本发明公开了一种穿越基坑围护结构浅埋管线的保护结构及保护方法，包括基坑围护结构，基坑围护结构包括基坑工法桩、RJP桩和基坑冠梁，四根RJP桩两两一组设置在浅埋管线下方基坑的两侧，基坑冠梁设置在基坑工法桩和RJP桩的上方以及浅埋管线的下方，基坑冠梁内侧壁设置有多根砼支撑预埋钢筋，多根砼支撑预埋钢筋锚固在基坑冠梁内侧并预留有接头，其中一侧砼支撑预埋钢筋接头上设置有预埋套筒，预埋套筒套设在接头外侧并紧贴基坑冠梁内侧面，另一侧砼支撑预埋钢筋接头悬空，承托保护结构，承托保护结构包括防护罩和砼支撑，防护罩位于浅埋管线的外侧，砼支撑位于防护罩下方以及基坑内土方上方。本发明可以避免管线的迁改施工，同时降低了施工成本。
