Soil bionic permeation enhancing device and implementation method thereof
The invention discloses a soil bionic permeation enhancing device and an implementation method thereof, and belongs to the technical field of rainwater drainage facilities, the permeation enhancing device comprises a drainage tube which simulates a main root of a plant and has a closed bottom end, and a flushing tube with a cover is mounted in the center of the drainage tube; an annular cavity between the drainage pipe and the flushing pipe is sequentially filled with coarse quartz sand and fine quartz sand from top to bottom; a plurality of branch pipes simulating plant lateral roots are inserted into the fine quartz sand section of the drainage pipe, the tail ends of the branch pipes are closed, and a plurality of water outlet holes are formed in the wall of the drainage pipe between the adjacent branch pipes; the branch pipes are filled with water absorption expansion materials, and a plurality of holes are evenly distributed in the walls of the branch pipes. According to the invention, the water-absorbing expansion material is squeezed into the soil by utilizing the expansion force generated after the water-absorbing expansion material absorbs water and rapidly expands in the limited space, so that the porosity of the soil is increased, the water permeability is improved, and the water content of the soil is improved by virtue of the water-absorbing characteristic of the high-water-absorbing expansion material.
本发明公开了一种土壤仿生增渗装置及其实现方法，属于雨水排渗设施技术领域，所述的增渗装置包括一个模仿植物主根的底端封闭的引流管，引流管中心安装一根带盖的冲洗管，在引流管与冲洗管之间的环形空腔从上到下依次充填粗石英砂和细石英砂；在引流管细石英砂段插入模仿植物侧根的多个分支管，分支管末端封闭，在相邻的分支管之间的引流管壁设置有多个出水孔；分支管内充填吸水膨胀材料，在分支管壁上均布设有多个孔洞。本发明利用在限定空间内吸水膨胀材料吸水快速膨胀后产生的膨胀力，将吸水膨胀材料挤入土壤，不仅增大土壤孔隙度，提高渗水性能，而且还凭借高吸水膨胀材料吸水特性提高土壤的含水量。
