Rock area combined type hole digging slide-resistant pile structure and construction method thereof
The invention discloses a rock area combined type hole digging anti-slide pile structure and a construction method thereof. The rock area combined type hole digging anti-slide pile structure comprises an anti-slide pile area, a ring beam arranged on the periphery of the anti-slide pile area, fender posts arranged on the ring beam and I-shaped steel arranged in the fender posts. The anti-slide pile area is provided with anti-slide piles located on the sliding face, the soil body comprises a hard rock layer, the anti-slide pile area is adjacent to the side slope and located on one side of the backfill square ditch, two rotary drilling holes are formed in the anti-slide pile area, and down-the-hole and expansion holes are further formed in the inner side of the periphery of the anti-slide pile area. According to the method, through earlier-stage treatment of the slip plane, slope arrangement and arrangement of the slide-resistant piles, follow-up collapse and movement of the follow-up slip plane can be effectively dealt with; through the arrangement of the rotary drilling hole, the down-the-hole and the expansion hole, excavation can be conducted in a rock stratum area, and tapping forming of the slide-resistant pile is guaranteed; and through the combined arrangement of the inverted wall type support, the connecting plate, the soil retaining plate and the like, the integral connection of the anti-sliding pile and the improvement of the anti-sliding performance can be ensured.
本发明公开了一种岩石区组合式挖孔抗滑桩结构及其施工方法，包含抗滑桩区、设置于抗滑桩区外周的圈梁、设置于圈梁上的围护桩以及设置于围护桩内的工字钢；抗滑桩区设置抗滑桩位于滑移面上且土体内包含坚硬岩石层，抗滑桩区紧邻边坡且位于回填方沟一侧，抗滑桩区内部设置有两个旋挖钻孔、抗滑桩区四周内侧还设置有潜孔和膨胀孔。本发明通过对滑移面的前期处理、边坡设置以及抗滑桩的布置，可有效的应对后续滑移面后续的坍塌和移动；通过旋挖钻孔、潜孔和膨胀孔的设置，可在岩层区进行开挖，保证抗滑桩的开孔成型；通过倒壁式支护、连板和挡土板等联合设置，可保证抗滑桩的整体性连接和抗滑移的性能的提升。
