Description

Technical Field

[0001] The utility model relates to a drainage device, in particular to a drainage device for roadbed and pavement design. Background Art

[0002] The drainage device of the road surface plays a vital role in road engineering. Its main function is to guide, collect and drain the water from the road surface, shoulders and slopes to ensure that the road can remain unobstructed on rainy days.

[0003] However, the common road surface drainage systems currently in use are relatively simple, primarily consisting of a gutter plate and a filter frame. When rainfall occurs, rainwater on the road converges into streams, often carrying debris such as fallen leaves and garbage onto the drainage system. This can easily clog the slots in the gutter plate and filter frame, compromising proper function. Severe road surface flooding not only creates inconvenience for vehicles and pedestrians but can also pose safety risks.

[0004] In view of this, we have proposed an innovative drainage device for roadbed and pavement design, which is specially equipped with an anti-blocking structure and a dredging structure, aiming to effectively solve the above technical problems and ensure the smooth operation of the drainage device. Utility Model Content

[0005] In order to overcome the problem that the existing road drainage devices have a relatively simple structure and usually do not have an active anti-blocking and automatic dredging structure, which easily causes blockage during use and leads to poor drainage, the purpose of this utility model is to provide a drainage device for roadbed and pavement design with an automatic dredging and anti-blocking structure.

[0006] The filter screen is located at the bottom of the filter frame, and the filter screen is located at the bottom of the filter frame. ...

[0007] Furthermore, the filter element includes a filter plate and a protrusion. The filter plate is provided at the bottom of the filter frame, and the protrusion is provided on the side of the filter plate.

[0008] Furthermore, the guide groove is aligned with the slot hole on the drainage trough plate.

[0009] Furthermore, a slot adapted to the protrusion is provided at the bottom of the filter frame.

[0010] Furthermore, the outer baffle frame and the inner baffle frame are distributed in an up-down staggered structure.

[0011] Furthermore, the upper portions of the outer baffle frame and the inner baffle frame are both designed to be bent inwards, so that an anti-blocking space is reserved between the outer baffle frame and the inner baffle frame and the inner wall of the filter frame.

[0012] Furthermore, the screen frame is designed to have a quadrangular pyramid structure that is wide at the top and narrow at the bottom.

[0013] The beneficial effects of the present invention are as follows: the anti-blocking structure composed of the outer baffle frame and the inner baffle frame which are staggered in the upper and lower parts is beneficial to further block and prevent the filter holes of the filter frame; and the dredging structure can utilize the buoyancy of the flowing water to automatically dredge and prevent the drainage trough plate, thereby enabling the device to maintain stable drainage in rainy days.
