Description

Outdoor road concrete pavement structure that permeates water Technical Field The utility model relates to the technical field of pavement construction, in particular to an outdoor road permeable concrete pavement structure. Background With the acceleration of the urban process, the problems of urban waterlogging, heat island effect and the like caused by the lack of water permeability of the traditional compact asphalt pavement are increasingly remarkable. Under the background, the permeable concrete pavement is used as an ecological friendly paving technology, and by virtue of the excellent functions of permeable, noise reduction, surface temperature regulation and the like, the permeable concrete pavement gradually becomes an important carrier for sponge city construction. However, pervious concrete still faces the risk of structural failure due to cracking of the substrate in practical applications. The traditional semi-rigid base layer (such as cement stabilized macadam) is easy to generate reflection cracks due to the temperature shrinkage and dry shrinkage characteristics, and the permeable concrete is high in self-porosity, so that the pavement is easy to crack, peel and other diseases under the action of heavy traffic and environmental stress, and the service life and the functionality of the pavement are seriously restricted. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides an outdoor road permeable concrete pavement structure so as to improve the crack resistance of the pavement and prolong the service life. In order to solve the problems, the outdoor road permeable concrete pavement structure provided by the utility model comprises a graded broken stone layer, a high-strength steel-plastic composite rib net layer and a permeable concrete layer; The grading gravel layer is paved on a roadbed, the high-strength steel-plastic composite rib net layer is paved on the grading gravel layer, and the permeable concrete layer is paved on the high-strength steel-plastic composite rib net layer; The permeability coefficient of the graded broken stone layer is more than or equal to 0.1cm/s, and the porosity of the permeable concrete layer is 15% -25%. Preferably, the thickness of the graded crushed stone layer is 200-250 mm. Preferably, the grid size of the high-strength steel-plastic composite reinforcement mesh layer is 100mm multiplied by 100mm to 150mm multiplied by 150mm. Preferably, the thickness of the permeable concrete layer is 200-400 mm. Preferably, transverse induction slits are arranged at intervals of 5-7 m along the longitudinal direction of the road. Preferably, the inducing seam is filled with polyurethane elastic sealant. The beneficial effects of the utility model are as follows: According to the utility model, a high-strength steel-plastic composite rib net layer is added between the permeable concrete layer and the graded broken stone layer to form a cooperative stress structure layer, the high-strength steel-plastic composite rib net layer is used as a three-dimensional reinforcement body, the shrinkage stress of a base layer can be dispersed, and crack expansion is restrained, meanwhile, the mesh structure is matched with the permeable concrete holes, so that the water permeability is not influenced, the industrial pain point of insufficient cracking resistance of the permeable concrete pavement is effectively solved, and through physical engineering verification, the outdoor road permeable concrete pavement structure can remarkably improve the cracking resistance of the pavement, effectively reduce crack generation, improve the integrity and durability of the pavement by more than 35%, reduce maintenance cost by about 45%, and have ecological benefit and economic benefit.
