Multi-stage supporting structure for slope protection surface of deep foundation pit and supporting method thereof
The invention discloses a multi-stage supporting structure for the slope protection surface of a deep foundation pit and a supporting method thereof. The multi-stage supporting structure comprises twoparallel transverse bars, a plurality of parallel longitudinal bars are equidistantly and fixedly arranged on the outer walls of the same sides of the two transverse bars and are positioned between the two transverse bars, and a plurality of parallel supporting bars are equidistantly and fixedly arranged on the outer sides of the two transverse bars. In the multi-stage supporting structure, by the structure provided with the supporting bars, the supporting bars, a grouting bent-plugging pipe and the longitudinal bars, the connection with the slope protection surface can be realized through the supporting bars, and the pumping of concrete slurry can be realized through the grouting bent-plugging pipe. Compared with the existing supporting spray anchor rod plugging and reinforcing mesh supporting modes, the supporting method realizes the fixing of a spray anchor rod and suspending operation of a reinforcing mesh by single operation, and thus the supporting efficiency of the slope protection surface of the deep foundation pit is greatly accelerated; and the outer part of the grouting bent-plugging pipe is connected with a grouting straight-plugging pipe, so that the deep soil of theslope protection surface can be grouted, and thus the supporting strength for the deep slope protection surface is improved.
本发明公开了一种深基坑护坡面多级支护结构及其支护方法，包括两个平行设置的横筋，两个所述横筋同侧外壁等距固定有多个平行设置的纵筋，多个所述纵筋介于两个横筋之间以及两个横筋的外侧均等距固定有多个平行设置的支撑筋。本发明中，通过设置支撑筋、横筋、注浆弯插管和纵筋的结构，能够通过支撑筋实现与护坡面进行连接，通过注浆弯插管实现混凝土浆料的泵送，相比于现有的喷锚杆插接和钢筋网支护方式，该种支护方式单次操作实现喷锚杆的固定和钢筋网的悬挂操作，从而大大加快深基坑护坡面的支护效率；通过将注浆弯插管的外部连接注浆直插管，能够对护坡面深层土壤进行注浆，从而提高对深处的护坡面支护强度。
