Drainage structure for road subgrade construction and construction method
The invention belongs to the technical field of road drainage, and particularly relates to a drainage structure for road subgrade construction and a construction method.The drainage structure comprises a drainage well, a drainage opening, a flow guide frame and an anti-blocking device, the anti-blocking device comprises an automatic screen changing assembly and a pressure relief assembly, and the automatic screen changing assembly comprises a filter screen, a first transmission unit and a second transmission unit; by arranging the first transmission unit, the second transmission unit, the filter screen and the pressure relief assembly, in rainstorm, if the filter screen is blocked, the amount of water accumulated on the filter screen is increased, the pressure is increased, the filter screen is driven by the first transmission unit and the second transmission unit to be automatically replaced, the blocked filter screen is replaced by a new filter screen, and meanwhile pressure relief is conducted through the pressure relief assembly. Accumulated water accumulated above the filter screen and the road surface when the filter screen is blocked is drained in time, the drainage effect is improved, after the filter screen is replaced, impurities on the pressure relief assembly are automatically cleaned, and the filtering effect during next pressure relief is conveniently guaranteed.
本发明属于道路排水技术领域，具体为一种道路路基施工的排水结构及施工方法，包括排水井、排水口、导流框和防堵装置，防堵装置包括自动换网组件和泄压组件，自动换网组件包括滤网、一号传动单元和二号传动单元，通过设置一号传动单元、二号传动单元、滤网和泄压组件，在暴雨时，若滤网发生堵塞，此时滤网上积聚的水量增多，压力增加，通过一号传动单元和二号传动单元带动滤网自动更换，用新的滤网更换出堵塞的滤网，并同时通过泄压组件泄压，将滤网堵塞时积聚在滤网上方和路面上方的积水及时排出，提高排水效果，滤网替换完成后，自动清理泄压组件上的杂质，便于保证下次泄压时的过滤效果。
