Roadbed drainage structure for municipal road construction
Technical Field
The utility model relates to the technical field of separation, in particular to a roadbed drainage structure for municipal road construction.
Background
Roadbed drainage is an important link for maintaining roadbed stability, and aims to effectively collect and drain surface water and underground water. In the construction of municipal roads, drainage measures are indispensable to cope with sewage and rainwater generated during construction. The current common way of draining the roadbed is to direct these bodies of water into gutters and catch basins. However, during construction, a large amount of sediment is often associated, and the sediment often flows into the drainage system along with sewage and rainwater, and gradually accumulates in the drainage ditch and the rainwater well to form a blockage risk. In order to prevent accumulation of sundries and silt in the drainage ditch, the prior art usually adopts a filter screen for preliminary filtration. However, over time, impurities and sludge can accumulate on the filter screen, and particularly, accumulation is easily formed on one side of the screen, and even the filter holes are blocked, so that the filtering effect is weakened. And the subsequent filter screen maintenance work, such as taking the filter screen out of the drainage ditch for cleaning, is time-consuming and also consumes a great deal of manpower.
