Study and Application of Equipment for Recovery the Function of Drainage Pavement A Dissertation Submitted for the Degree of Master Candidate: Yukui Yan Supervisor：Prof. Shengjie Jiao Prof. Tingguo Liu Chang’an University, Xi’an, China 摘 要 排水性沥青路面具有抗滑性能高、噪声低、抑制水雾、防止水漂、减轻眩光等突出 优点得以广泛应用。但此路面受环境影响会出现因灰尘等杂物堵塞路面空隙，降低排水 机能，维持其排水机能的养护技术及设备在国内还处于起步阶段。本文采用“高压水冲 洗+气穴清洗+真空抽吸” 的作业模式，研制HGY5250TPH 型排水性路面机能恢复车，实 现对堵塞路面机能恢复的机械养护。 论文在分析排水性沥青路面机能恢复车高负压抽吸、气穴效应、污水回收及循环利 用、结构原理和施工工艺要求的基础上，提出一种结构合理、满足排水性路面机能恢复 养护要求的技术设备，能够冲洗清理堵塞在排水性沥青路面内部的灰尘、泥沙等杂物， 并可将清理出来的杂物进行集中回收处理，恢复被堵塞路面的排水机能，使其符合使用 要求。在此基础上进行排水性路面机能恢复装备设计，并在实际施工中进行系统测试及 应用效果研究。 实验清洗结果表明，国产排水性沥青路面机能恢复车无论对于浅层或深层堵塞都有 明显的清洗效果，能在很大程度上恢复排水性沥青路面的排水功能，排水性沥青路面的 排水机能可恢复到新建时期的 60% 以上，回复效果明显。HGY5250TPH 型排水性沥青 路面机能恢复车的研发，为排水性沥青路面养护提供了一种新方法。 关键词：排水性沥青路面，机能恢复，负压抽吸，气穴效应，透水率 I Abstract The porous asphalt pavement is adopted porous asphalt as its surface layer, so the rainfall penetrates into the drainage function layer and crosswise drain away, since the porous asphalt paving with big interspaces character possess the obvious virtues of anti-skating, lower noisy, restrain water mist, prevent blanching and reduce glare, it’s popular used in developed countries and promoted at seaboard area domestically. However, this type of pavement is affected by environment, the interspaces would be blocked with dust or sundries, thus reduces the drainage function, the maintenance technology and equipment of keeping its drainage function is still in the fledging period. On the current basis of mechanical, hydraulic and electronic control
