【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。
[Abstract]:Drainage asphalt pavement has been widely used in many fields, such as high skid resistance, low noise, controlling water mist, preventing water drift and reducing glare. However, the maintenance technology and equipment of the pavement due to dust and other debris will clog the gap of the pavement, reduce the drainage function and maintain the drainage function in China is still in its infancy. In this paper, the working mode of "high pressure water washing cavitation cleaning vacuum suction" is adopted to develop HGY5250TPH type drainage pavement function recovery vehicle, which can realize the mechanical maintenance of the function recovery of blocked road surface. Based on the analysis of high negative pressure suction, cavitation effect, sewage recovery and recycling, structural principle and construction technology requirements, a reasonable structure is put forward in this paper. The technical equipment that meets the requirements of functional restoration and maintenance of drainage pavement can wash and clean the dirt, silt and other sundries blocked inside the drainage asphalt pavement, and can collect and dispose the sundries that have been cleaned out in a centralized way. Restore the drainage function of the blocked road surface to meet the use requirements. On the basis of this, the function recovery equipment of drainage pavement is designed, and the system test and application effect are studied in actual construction. The experimental cleaning results show that the function recovery vehicle of domestic drainage asphalt pavement has obvious cleaning effect for shallow or deep layer clogging, and can restore drainage function of drainage asphalt pavement to a great extent. The drainage function of drainage asphalt pavement can be restored to more than 60% of that of the new construction period, and the recovery effect is obvious. The research and development of HGY5250 TPH type drainage asphalt pavement function recovery vehicle provides a new method for the maintenance of drainage asphalt pavement.
