Variable cross-section combined slide-resistant pile with upper part and lower part being circular and construction method thereof
The invention discloses a variable-cross-section combined anti-slide pile with the upper portion and the lower portion being round and a construction method of the variable-cross-section combined anti-slide pile. A pile body of the slide-resistant pile is divided into two parts, the cross section of the upper part is rectangular, and the cross section of the lower part is circular. The method is mainly applied to shallow-layer and medium-thickness-layer landslides of a binary stratum structure with the square upper portion and the round lower portion (upper portion and lower portion for short), rectangular-section piles are excavated in an upper soil layer manually, and round-hole anti-slide piles are excavated in a lower bed rock mechanically. The anti-slide pile is a pile column penetrating through a landslide body or backfill soil and going deep into a slide bed, is used for supporting and blocking the sliding force of the landslide body, can effectively enhance the slope stability, and is suitable for shallow and medium-thickness landslides of an upper soil body and a lower rock layer (upper soil and lower rock for short) binary stratum structure, and earth and rockfill bodies such as embankments and earth and rockfill dams. The section of the upper portion of the pile is rectangular and meets the requirement for skid resistance of the pile, the section of the lower portion of the pile is round facilitating mechanical construction, and construction safety, convenience and skid resistance stability are achieved.
本发明公开了一种上方下圆的变截面组合抗滑桩及其施工方法，其特征在于；抗滑桩的桩身分为两部分，上部分横截面为矩形，下部分横截面为圆形；主要应用于上部方形、下部圆形(简称上方下圆)二元地层结构的浅层和中厚层滑坡中，上部土层由人工开挖矩形截面桩，下部基岩由机械开挖圆孔抗滑桩。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(简称上土下岩)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。桩上部截面为矩形，满足桩的抗滑性，下部截面为便于机械施工的圆形，兼具施工安全、便捷性和抗滑稳定性。
