Slope deep-layer anti-sliding construction method
The invention relates to the technical field of foundation treatment slope body protection construction, and discloses a slope deep-layer anti-sliding construction method which comprises the following steps that S1, a reaming base is placed at a to-be-constructed position, and a rod hammer of construction equipment is aligned with a point position; s2, the chambering base is repeatedly tamped by a rod hammer, and the chambering base is pushed to penetrate through the soft soil layer and enter a stable original-state old soil layer; s3, the rod hammer is pulled out, the reaming base is hoisted out, and a complete and firm pile hole is formed in an inner cavity of the soil layer; s4, a reinforcement cage is installed in the pile hole, and hard concrete is poured; s5, the compacted concrete is hammered again through the rod hammer, the reinforced concrete anti-sliding hidden anchor pile is formed, and the rod hammer is hoisted out and moved away; and S6, the upper pile hole replacement material is backfilled, compaction continues to be conducted, and a complete anti-slide pile reinforcement is formed. The reinforcement cage is embedded into the original rock-soil layer to form the short pile pier-shaped support so as to prevent the upper soil layer from settling and sliding due to excessive compression; and the short piles are less in material consumption, higher in anti-sliding capacity and less prone to being broken, and meanwhile the treatment cost is greatly reduced.
本发明涉及地基处理坡体防护施工技术领域,公开了一种斜坡深层抗滑移施工方法，包括以下步骤：S1、在待施工处安放扩孔底座，施工设备的棒锤对准点位；S2、棒锤反复夯击扩孔底座，推动扩孔底座穿透软弱土层，进入稳定原状老土层；S3、拔出棒锤，吊出扩孔底座，土层内腔形成完整坚实的桩孔；S4、在桩孔内安装钢筋笼，灌注干硬性混凝土；S5、通过棒锤再次锤击夯实砼，形成钢筋混凝土抗滑移暗锚桩，吊出移开棒锤；S6、回填上部桩孔置换料，继续夯击密实，形成完整抗滑桩增强体。本发明通过用钢筋笼嵌入原状岩土层形成短桩墩形支承，以阻止上部土层因过度压缩而导致沉降滑移；且短桩用料更少，抗滑移能力更强更不容易被折断，同时大幅降低处理造价。
