Description

Technical Field

[0001] The utility model relates to the technical field of road engineering, and more specifically to a side wall supporting structure of a drainage ditch on an asphalt pavement. Background Art

[0002] Asphalt pavement grooving technology is a simple and easy-to-construct drainage technology, generally used in super-elevation transition sections of highways, that is, sections prone to water accumulation. In order to prevent deformation of the drainage ditch, a supporting structure component is installed inside the drainage ditch. However, the construction of the supporting structure component is time-consuming, which reduces the construction efficiency. In addition, its supporting area and strength are limited, which reduces the supporting stability of the supporting structure.

[0003] For example, announcement number CN117432045A discloses a side wall support structure of an asphalt pavement drainage ditch, comprising: a trough body, evenly distributed on the asphalt pavement; an I-shaped trough inner wall support frame, arranged in the trough body and close to the inner wall of the trough body; the I-shaped trough inner wall support frame comprises a first longitudinal support plate, a second longitudinal support plate and a transverse connecting member, the first longitudinal support plate and the second longitudinal support plate respectively abut against two opposite inner walls inside the trough body, and a plurality of the transverse connecting members are arranged between the first longitudinal support plate and the second longitudinal support plate.

[0004] It can be seen from the above-mentioned public scheme that a number of the said transverse connecting members are arranged between the first longitudinal support plate and the second longitudinal support plate, and the number of the transverse connecting members is large, and the installation is relatively cumbersome and time-consuming, and the supporting area of ​​the transverse connecting members is small, thereby reducing the supporting strength of the first longitudinal support plate and the second longitudinal support plate, so that the upper and lower ends of the first longitudinal support plate and the second longitudinal support plate may be deformed during use, thereby reducing the support stability.
