Description

TECHNICAL FIELD

[0001] The utility model relates to the field of highway drainage, especially a roadbed drainage structure. BACKGROUND

[0002] The roadbed drainage structure is an important component in road engineering, mainly used for draining surface water and groundwater within the roadbed range to maintain the stability and strength of the roadbed. A good drainage system can prevent water from penetrating into the roadbed material, avoiding hazards such as softening, frost heaving, and frost boiling caused by excessive water, thereby ensuring the quality of the road and prolonging its service life.

[0003] The patent with the authorization disclosure number CN222083708U discloses a highway base drainage structure, which includes a highway body. Two drainage grooves are formed inside the highway body. Two sliding openings are formed on the inside top surface of the drainage grooves. A sliding plate is slidably arranged inside the sliding openings. Several sliding rods are fixed to the inside top surface of the drainage grooves. A fixed plate is detachably installed on the bottom surface of the sliding plate. A sliding hole is formed on the top surface of the fixed plate. The sliding rods and the sliding hole are slidably connected. Although the above-mentioned patent can avoid the influence of fallen leaves on the drainage volume by sliding the sliding plate downward from the inside of the sliding opening, the water flow mixed with fallen leaves will remain in the gap between the sliding plate and the sliding opening, thereby increasing the drainage effect. However, the drainage system mainly relies on the design of the sliding plate and the drainage groove, and the drainage path is relatively single. In heavy rain or storm weather, a large amount of accumulated water may not be quickly drained, increasing the risk of waterlogging. Moreover, since the accumulated water cannot be quickly drained, the water accumulated on the road surface for a long time may gradually penetrate into the roadbed material, affecting the stability and strength of the roadbed, and thus shortening the service life of the road.
