Construction technology for digging round hole in square pile of slide-resistant pile
The invention discloses a construction process for digging a round hole in a square pile of an anti-slide pile. The construction method comprises the following steps: (1) firstly, manually digging a rectangular construction platform with the depth of 2-4m on the ground according to the size of the designed square pile; (2) at the bottom of the square foundation pit, according to the designed round pile size, a mechanical hole forming mode is adopted, a round pile outline (a round vertical shaft) is dug, and then manual trimming is conducted to form a rectangular hole; (3) the reinforcement cage is placed in the circular vertical shaft, and concrete is poured; and (4) the square pile above the ground is supported through a wood formwork, and one-time concrete pouring is completed. The slide-resistant piles penetrate through a landslide body or backfill soil and go deep into pile columns of a slide bed, are used for supporting and blocking the sliding force of the slide body, can effectively enhance the slope stability, and are suitable for shallow-layer and medium-thick-layer landslides of an upper soil body and a lower rock layer binary stratum structure and earth and rock fill bodies such as embankments and earth and rockfill dams.
本发明公开了一种抗滑桩方桩挖圆孔施工工艺,施工方法包括:(1)先在地面处按设计方桩尺寸采用人工开挖深度2~4m的矩形施工平台;(2)在方形基坑底部,按设计圆桩尺寸,采用机械成孔方式,开凿圆形桩轮廓(圆形竖井),再人工修边成矩形孔;(3)将钢筋笼置入圆形竖井中,并浇筑混凝土;(4)地面以上方桩采用木模板支模,一次浇筑混凝土完成。所述抗滑桩是穿过滑坡体或回填土并深入滑床的桩柱,用以支挡滑体的滑动力,能有效增强边坡稳定性,适用于上部土体、下部岩层二元地层结构的浅层和中厚层滑坡和路堤、土石坝等土石堆填体。
