Roadbed humidity control and drainage intelligent device based on modified water-absorbent resin and application method of roadbed humidity control and drainage intelligent device
The invention belongs to the technical field of roadbed humidity control and drainage, particularly relates to an intelligent roadbed humidity control and drainage device based on modified water-absorbent resin and an application method of the intelligent roadbed humidity control and drainage device, and aims at solving the problems that an existing roadbed cannot adsorb and discharge roadbed moisture and is prone to causing disasters. An improved roadbed layer is laid on the top of the foundation, a pavement layer is laid on the top of the improved roadbed layer, a first drainage device is arranged between the foundation and the improved roadbed layer, and a pavement layer second drainage device is arranged between the foundation and the improved roadbed layer. The drainage device comprises the following components: a double-layer high-suction geotextile, 4-10% of modified water-absorbent resin, flocculent filler and a humidity-sensitive material, the improved roadbed layer is prepared from the following components in percentage by weight: 0.4 to 1 percent of macromolecular hydrophobic agent. The method is convenient to operate, and the roadbed internal drainage device capable of draining water through high suction force difference is prepared by matching the modified water-absorbent resin.
本发明属于路基控湿排水技术领域，尤其是一种基于改性吸水树脂的路基控湿排水智能装置及其应用方法，针对现有的路基不能对路基水分进行吸附和排出，容易引发灾患的问题，现提出如下方案，其包括地基，地基的顶部铺设有改良路基层，改良路基层的顶部铺设有路面层，地基与改良路基层之间设置有第一排水装置，改良路基层与之间设置有路面层第二排水装置；排水装置的的成分包括以下：双层高吸力土工织物、改性吸水树脂4‑10％、絮状填充物、湿敏性材料；改良路基层的成分包括以下重量百分比：高分子疏水剂量0.4‑1％。本发明操作方便，利用改性吸水树脂配合制备可通过吸高吸力差排水的路基内部排水装置。
