Title:
ENVIRONMENT-FRIENDLY ROAD CONSTRUCTION EQUIPMENT FOR PHOTOVOLTAIC POWER STATION, AND ROAD STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2024/041413
Kind Code:
A1
Abstract:
The present invention relates the field of permanent and temporary road construction, and particularly provides environment-friendly road construction equipment for a photovoltaic power station, and a road structure. The road structure comprises a roadbed, a base trough, graded crushed stones, medium-coarse sand, block stones and a mixture. A base course of a certain thickness is laid with the graded crushed stones at the bottom of the base trough which is excavated on the roadbed and has an inverted trapezoidal cross section. A bed course of a certain thickness is laid with the medium-course sand on the graded crush stone base course. A surface course is laid on the medium-coarse sand bed course with one layer of block stones with large sizes and regular shapes. In the road structure of the present invention, the surface course is manually paved with block stones with large relative sizes and relatively regular shapes. The block stones are caulked by using the mixture. The block stones at the surface of the surface course is slightly higher than the mixture, such that the surface of the surface course has a tiny roughness. A vehicle is mainly in contact with the block stones in a traveling process, and direct contact between the traveling vehicle and the mixture is avoided, such that dust generation on the road surface is effectively controlled.
