Top-down construction method for flood control and drainage riverway slope protection and ecological clamping body
The invention discloses a top-down construction method for a flood control and drainage riverway slope protection and an ecological clamping body. The construction method comprises the steps of designing before construction; firstly, excavating from the position of the highest point of the riverway slope protection, arranging a first-stage slope surface and a stepped horizontal operation road, and splicing the ecological clamping body to the top of the slope surface to form a first-stage slope protection surface; continuously constructing to form a second-stage slope protection surface and a second-stage stepped horizontal operation road, pouring the first-stage stepped horizontal operation road, closing the bottom of the first-stage slope protection surface and the top of the second-stage slope protection surface to form a closed hardened road surface till the Nth time, and forming a multi-stage slope protection surface and a multi-stage stepped horizontal operation road till the bottom depth of a riverbed reaches the designed depth; and finally, working with water, splicing the ecological clamping body, and pushing the ecological clamping body downwards into the slope surface in water to form a last-stage slope protection surface. According to the top-down construction method, construction is conducted from top to bottom, and matched operation and cross operation with river dredging are facilitated; and the top-down construction method is favorable for increasing the sectional area of riverway water flow and reducing the water level, so that flood control and drainage are realized.
本发明公开了一种防洪排涝河道护坡自上而下施工方法及生态卡接体，施工方法包括施工前设计；先从河道护坡最高点的位置开始开挖，整理出第一级坡面和阶梯式水平作业道路，将生态卡接体拼接至斜坡面顶部形成第一级护坡面；继续施工形成第二级护坡面及第二级阶梯式水平作业道路，浇筑第一级阶梯式水平作业道路，封闭第一级护坡面的底部及第二级护坡面的顶部，形成封闭硬化路面，直到第N次，形成多级护坡面及多级阶梯式水平作业道路，直到河床底部深度达到设计的深度；最后带水作业，拼接生态卡接体，向下推入水中坡面，形成最后一级护坡面。本发明自上而下施工，方便与河道清淤配合作业和交叉作业；对扩大河道水流量截面积和降低水位有利，从而实现防洪排涝。
