Anchor cable supporting structure for foundation pit and construction method
The invention discloses an anchor cable supporting structure for a foundation pit and a construction method thereof. The anchor cable supporting structure comprises a plurality of anchor cable supporting pieces, wherein each anchor cable supporting piece comprises an anchor hole and a pre-stressed anchor cable body, one end of each pre-stressed anchor cable body is fixedly connected with the corresponding anchor hole, the other end of each pre-stressed anchor cable body extends out of the corresponding anchor hole and is connected with an anchor backing plate, the anchor bearing plates abut against the side wall of the foundation pit, and the side wall of the foundation pit has the structural strength for supporting the anchor bearing plates. The construction method comprises the steps that the foundation pit is excavated in a layered mode, and protection is performed along with excavation every layer, that is, construction of one layer of anchor cable supporting pieces is completed after each layer is excavated. According to the anchor cable supporting structure, on the premise that the side wall of the foundation pit has enough structural strength, supporting of the foundation pit is achieved through the anchor cable supporting structure, the supporting construction period is short, materials and labor are few, supporting is stable, follow-up dismantling is not needed, and good economical efficiency is achieved.
本发明公开了一种基坑用锚索支护结构及其施工方法，所述锚索支护结构包括多个锚索支护件，所述锚索支护件包括锚孔和与预应力锚索体，所述预应力锚索体的一端与锚孔固接，所述预应力锚索体的另一端伸出锚孔外并连接有锚垫板，所述锚垫板与基坑侧壁抵接，且所述基坑侧壁具有支撑锚垫板的结构强度。所述施工方法包括基坑分层开挖，且开挖一级防护一级，即每开挖一层便完成一层锚索支护件的施工。本发明在基坑侧壁具有足够结构强度的前提下通过锚索支护结构实现对基坑的支护，不仅支护施工周期短，而且用料用工少、支护稳定且无需后续拆除，具有良好的经济性。
