Water-permeable sidewalk surface course pavement structure and pavement method

Abstract

The invention discloses a water-permeable sidewalk surface course pavement structure and pavement method. Baffle bars which are mutually parallel and perpendicular to the road axis are fixed on a water-permeable or / and water draining roadbed surface course in a two-two spaced mode; multiple grid bars parallel to the baffle bars are arranged on the portion, between every two baffle bars, of the roadbed surface course at intervals; multiple sidewalk surface course paving blocks of which the bottom faces are attached to the roadbed surface course in a contact mode and the specifications are the same are paved between every two adjacent grid bars; elastic wedge blocks are wedged between every two adjacent surface course paving blocks clamping one grid bar. By means of the surface course pavement structure, the anti-settling capacity of a sidewalk can be improved, the situation that a water-permeable road surface is paved with drainage bricks made of an impermeable material can be achieved, the compression resistance and fracture resistance of the road surface paving blocks can be greatly improved, and the maintenance cost of the sidewalk can be reduced; the surface course paving blocks do not need to be cemented with concrete, and any surface course paving block can be taken out of the road surface for replacing when the surface course paving block is damaged; therefore, dismounting, mounting and maintaining of a sidewalk pavement are very convenient, the road surface does not need to be broken and dismounted, and a roadbed cannot be damaged.

Description

technical field [0001] The invention relates to the pavement pavement of a permeable walkway, in particular to a pavement structure and a pavement method of a permeable walkway surface. Background technique [0002] The anti-compression and anti-settling performance of the pavement after the permeable pavement is mainly determined by the soil quality and compactness of the subgrade, the thickness and compaction of the permeable gravel layer, the quality of the permeable concrete and the thickness of the pavement, and the quality of the permeable geotextile. layer factors. The compressive and flexural properties of permeable sidewalk surface pavement are mainly determined by the plane geometry of the surface permeable pavement, the maximum span size of the plane, the thickness of the pavement, and the material of the pavement. [0003] Under the premise of the same design index and the same standard of construction technology, the existing technology is mainly realized throu...

Problems solved by technology

Most of these technologies improve the compression and anti-settling properties of permeable pavement pavement by improving the cushion structure of the permeable surface pavement in the direction of the vertical structure, but the cost is also increased accordingly
