Permeation well type rainwater collection and permeation sponge city construction method and device
The invention relates to an infiltration well type rainwater collection and infiltration sponge city construction method. The method comprises the following steps that S1, rainwater well point locations are arranged according to the maximum rainfall and a rainwater collection area; s2, a rainwater well hole is drilled through a drilling machine, and when the stratum is soft, the mode that a steel pipe pile is driven in first, soil is taken in the pile, and then a hole is directly formed is adopted; s3, a single-section non-fine concrete pipe is hoisted by a crane and vertically placed into the drilled hole, the non-fine concrete pipe is made to be matched with the center of the hole, for non-lithologic soil, filter gravel is laid at the well bottom, and then a well lid is covered; and S4, a plurality of steel pipes are evenly inserted into the periphery of the well to the bottom of the hole, after the periphery of the well is filled with sand to form a medium-coarse sand filtering layer, slurry in the medium-coarse sand filtering layer is flushed in the mode that pressure water is injected into the steel pipes, and the steel pipes are pulled out in time after the periphery is backfilled with the medium-coarse sand. The problems of rain flooding and dry land can be solved, the ground surface area is not occupied, even the rain collecting well can be used as a foundation of a structure, and a sponge city pattern is effectively formed.
本发明涉及一种渗透井式雨水收集、渗透的海绵城市建造方法，包括以下步骤：S1、根据最大降雨量及集雨区域布局雨水井点位；S2、用钻孔钻机钻雨水井孔，当地层较软时，采取先打入钢管桩、桩内取土后直接成孔的方式；S3、用吊车吊起单节无砂混凝土管垂直放入钻好的孔中，并使无砂混凝土管与孔中心吻合，对于非岩性土，在井底铺垫过滤碎石，然后盖上井盖；S4、在井周均匀插入多根钢管到孔底，在井周填砂形成中粗砂滤层后，通过向钢管内注入压力水的方式冲洗中粗砂滤层中的泥浆，在周边中粗砂回填后及时将钢管拔出。本发明不仅可解决雨淹旱干的问题，且不占用地表面积，甚至集雨井可用于结构物的基础，有效形成海绵城市格局。
