Multistage assembly type ecological water recession system for hydraulic reclamation area and construction method
The invention relates to a construction method of a multi-stage assembly type ecological water recession system in a hydraulic reclamation area, which comprises the following steps of: manufacturing a base and an annular precast block, and arranging an embedded threaded sleeve and a lifting ring in the base and the annular precast block; a base and a drainage pipe are installed at the lower terrain of the hydraulic reclamation area, and backfilling and tamping are conducted; the annular precast blocks are stacked on the base layer by layer and fixed through the connecting screws, and the outer sides of the annular precast blocks are wrapped with geotechnical cloth; a first-stage filter basket, a second-stage filter basket and a third-stage filter basket which are appropriate in size are selected to be assembled into a multi-stage filter basket filtering system, the multi-stage filter baskets are hung on the top-layer annular prefabricated block, and the outer sides of the annular prefabricated blocks are sleeved with vertical filter cylinders; mud is conveyed to the hydraulic reclamation area, and hydraulic reclamation operation is started; in the hydraulic reclamation process, silt in the multi-stage filter basket is cleaned in time, and an annular precast block is additionally arranged; after hydraulic reclamation is completed, the annular precast blocks and the base are hoisted out of the sedimentary soil layer layer by layer; and backfilling pits left by the base and the annular precast blocks in the sedimentary soil layer by layer by using backfill soil.
本发明涉及的吹填区多级装配式生态退水系统施工方法，包括以下步骤：制作底座及环形预制块，在底座及环形预制块内设置预埋螺纹套筒及吊环；在吹填区地势较低处安装底座及排水管，并回填夯实；在底座上逐层堆放环形预制块并使用连接螺杆固定，并在环形预制块外侧包裹土工布；选择合适大小的一级滤篮、二级滤篮、三级滤篮组装成多级滤篮过滤体系，并将多级滤篮吊挂在顶层环形预制块上，将竖向滤筒套在环形预制块外侧；向吹填区输送泥浆开始吹填作业；吹填过程中及时清理多级滤篮内的泥沙并增设环形预制块；吹填完成后，逐层将环形预制块及底座从沉积土层内吊出；使用回填土逐层将底座及环形预制块在沉积土层内留下的坑洞回填。
