Description

Technical Field

[0001] The utility model relates to the technical field related to drainage devices, and in particular to a roadside assembled drainage device. Background Art

[0002] In highway construction, the construction of the roadbed will affect the stability and strength of the highway construction. Drainage has always been one of the indispensable and important contents of the roadbed project. The existence of accumulated water has a serious adverse effect on the stability and service life of the road. In order to ensure the quality of highway roadbed construction, it is particularly important to do a good job in the drainage construction of the roadbed.

[0003] In the construction of highways in my country, the drainage facilities of a considerable number of roads are not perfect. Some roads do not have drainage systems. Waterlogging on the road will directly affect the safety of car driving. The water seeps into the roadbed, reducing the service life of the roadbed. Excessive water carries garbage into the roadside greening area and nearby farmland and rivers, causing the accumulation of domestic garbage and silt, polluting the soil and rivers, and causing farmland disasters. With the increase in service life, traffic flow and construction and development in nearby areas, the drainage system structure of some roads has been damaged, separated from the local water conservancy facilities, and the highway drainage system has become a separate entity, directly leading to the paralysis of the entire drainage system.

[0004] Therefore, based on the above problems, the utility model proposes a roadside assembled drainage device. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a highway roadside assembled drainage device in response to the above-mentioned existing technology, while solving the problems existing in the existing technology such as accumulation of surface water on the road surface, high cost of drainage facilities, difficult maintenance, easy accumulation of garbage, pollution of water and land, etc.
