一种基于亲水吸附与负压吸附的路面钻孔取样装置

本发明公开了一种基于亲水吸附与负压吸附的路面钻孔取样装置，包括连接有钻头的钻机本体，钻机本体的前端可拆卸连接有与钻头同轴的收纳筒，收纳筒内设置有与钻头相连的抽风扇叶、围绕钻头的亲水海绵，收纳筒的前端设置有弹性裙边，弹性裙边与地面接触的环面上设置有与收纳筒内腔连通的负压环槽，收纳筒的后端设置有用于抽风扇叶向外排气的滤袋。本发明解决泥浆外溢核心痛点：弹性裙边贴合地面形成密封腔体，负压环槽配合抽风扇叶产生持续负压，从源头约束泥浆扩散，彻底避免泥浆滴落、飞溅污染路面及周边环境。本发明采用双吸附协同提升收集效率，确保了氯离子、硫酸根离子等检测结果准确，降低了作业成本与劳动强度，延长了路面服役寿命。
