Construction method of sand-based breathable anti-seepage blanket for heavily polluted water body transformation
The invention relates to a construction method of a sand-based breathable anti-seepage blanket for heavily polluted water transformation, the construction method comprises the following steps: step 1, leveling a construction site, and rolling for multiple times to form a flat layer; 2, laying graded broken stone on the flat layer, and forming a base layer after compaction operation; 3, laying coarse sand on the graded broken stone, and forming a leveling layer; 4, laying a sand-based anti-seepage blanket on the leveling layer, and evenlying scattering bonding powder at the lap joint position of the sand-based anti-seepage blanket; 5, laying fine sand on the sand-based anti-seepage blanket, and forming a sand-based anti-seepage blanket protection layer; and 6, backfilling planting soil to cover the sand-based anti-seepage blanket protection layer so as to form a planting soil layer. According to the invention, a heavily polluted water source can be prevented from going up to a water body, meanwhile, pores among sand grains are used for ventilation, oxygen is provided for the water body, a ventilated living environment is provided for aquatic plants and arbors, and the double effects of seepage prevention and ventilation are achieved.
本发明涉及一种用于重污染水体改造的砂基透气防渗毯的施工方法,包括如下步骤:步骤一:对施工场地进行平整作业,并碾压多遍后,形成平整层;步骤二:在平整层上铺设级配碎石,并进行压实作业后形成基础层;步骤三:在级配碎石上铺设粗砂,形成找平层;步骤四:在找平层上铺设砂基防渗毯,在砂基防渗毯的搭接处均匀撒粘接粉;步骤五:在砂基防渗毯上铺设细砂,形成砂基防渗毯保护层;步骤六:回填种植土壤以覆盖砂基防渗毯保护层,以形成种植土壤层。本发明可以防止重污染水源上反至水体,同时利用砂粒间孔隙透气,为水体提供氧气,给水生植物和乔木提供透气的生存环境,起到了防渗、透气的双重效果。
