Lifting debris flow blocking structure and construction method
According to the liftable debris flow blocking structure and the construction method, a raft foundation with a pile core is built in a debris flow gully in a region with a relatively smooth longitudinal slope in the debris flow flowing direction, the pile core is sleeved with a movable steel pipe shell, the steel pipe shell and a pile core cavity are filled with coarse sand, and the steel pipe shell hoops waste tires; the movable steel pipe shells are connected into a whole through the tops of the movable steel pipe shells through connecting beams, a debris flow pile forest structure capable of buffering collision and being integrally stressed is formed, after debris flow occurs and silt is deposited in front of the blocking dam to form a full silt dam, the connecting beams are continuously stretched upwards to enable the bottoms of the movable steel pipe shells to reach the tops of the pile cores, and then concrete is poured into the movable steel pipes. And after the concrete is solidified, reinforced concrete grids are poured at the contact positions of the movable steel pipes and the triangular pile cores, so that a shell of the movable steel pipes poured with the concrete forms a two-layer pile forest and an overflowed raft foundation, the triangular pile cores and the grids form a two-layer debris flow pile forest structure, and debris flow continues to be blocked.
可抬升式泥石流拦挡结构及施工方法，本发明在泥石流沟内的泥石流流动方向纵坡较为平缓地区修建带有桩核的筏板基础，桩核上套接活动钢管外壳，钢管外壳和桩核空腔填充粗砂，钢管外壳套箍废旧轮胎，顶部通过连梁将活动钢管外壳连为一体，形成能够缓冲碰撞、整体受力的泥石流桩林结构，待泥石流发生，淤泥在拦挡坝前淤积形成满於坝后，通过连梁不断向上拉伸使活动钢管外壳底部达到桩核顶部，然后在活动钢管内浇筑混凝土，待混凝土凝固完成后在活动钢管和三角形桩核接触位置处浇筑钢筋混凝土格栅，使浇筑有混凝土的活动钢管外壳形成二层桩林与满溢的筏板基础、三角形桩核和格栅形成二层泥石流桩林结构，继续拦挡泥石流。
