Description

Technical Field

[0001] The utility model relates to the technical field of road surface drainage, and more specifically, to a transverse drainage device for a road surface at the straight-slow-flat slope of a curve superelevation section. Background Technique

[0002] On the straight-slow-flat slope of the curve superelevation section of the highway road surface, water accumulates to form a water-covered road surface. Vehicles traveling at high speeds are prone to traffic accidents, endangering the personal and property safety of drivers and passengers, and also prone to traffic accident disputes. The problem of road surface water accumulation has always troubled the operation and management units. When it rains, the operation and management units need to invest a large amount of manpower and material resources to remove the road surface water and place safety warning signs to minimize the occurrence of traffic accidents, resulting in a large waste of manpower and financial resources.

[0003] Based on the above problems, we provide a transverse drainage device for a road surface at the straight-slow-flat slope of a curve superelevation section.

[0004] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the utility model. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Content of the Utility Model

[0013] Preferably, the main frame is assembled on the super-elevation section of the curve of the highway pavement through C30 reinforced concrete at the position where the cross slope of the road crown is 0%.

[0014] Preferably, the top of the C30 reinforced concrete is covered with an asphalt concrete layer.

[0015] In summary, the utility model includes the following beneficial technical effects:

[0016] By opening a placement groove at the straight-slow-flat slope of the super-elevation section of the curve of the highway pavement, then placing the main frames inside the main frame in sequence, using the main frames to form a drainage channel, and then filling the placement groove with C30 reinforced concrete, the main frame and the C30 reinforced concrete are integrated.

The convex strip 6 on one main frame 1 fits into the notch 5 on another main frame 1 to complete the assembly of the two main frames 1.

[0030] Specifically, a plurality of convex pads 7 are fixedly connected to the top of the top plate 3 relative to the positions of the water inlet holes 4 for indicating the top plate 3.

[0031] Specifically, the main frame 1, the drainage body 2 and the top plate 3 are integrally formed structures.

[0032] Specifically, the main frame 1, the drainage body 2 and the top plate 3 are made of resin concrete (bonded by unsaturated polyester resin UPR, natural quartz sand and additives, with the resin content greater than 20%, and other types of resins cannot be used; the volume of the side ditch per meter is 0.054m 3 ).

[0033] Specifically, a plurality of arc grooves 8 are equidistantly opened on the side surface of the main frame 1.
