Detailed Description
The technical solution of the present application will be clearly and completely described below with reference to the accompanying drawings.
As shown in fig. 1-2, the permeable pavement disclosed in the present application includes a base layer 1, a buffer layer 2 and a permeable layer 3, which are sequentially arranged from bottom to top, wherein the base layer 1 is a plain soil layer, the buffer layer 2 is formed by ramming gravel and plain soil, the permeable layer 3 includes a permeable concrete layer 4 and a permeable brick layer 5, which are sequentially arranged from bottom to top, a plurality of drain pipes 6 along the width direction of the base layer 1 are horizontally embedded in the permeable concrete layer 4, the drain pipes 6 are arranged at intervals along the extending direction of the base layer 1, and two ends of the drain pipes 6 are open and protrude from the side surface of the base layer 1 in the width direction; drain pipe 6 upper end cambered surface week side runs through and has been seted up a plurality of holes 7 of permeating water, and a plurality of drain pipes 6 are the multirow and lay and every row all set up along 6 length direction of drain pipe, and drain pipe 6 is provided with in the hole 7 department of permeating water and filters the piece, and specific filtration piece sets up to wrap up geotechnological cloth layer 8 at 6 outer walls of drain pipe, and geotechnological cloth layer 8 is the heliciform around the package on 6 cambered surface outer walls of drain pipe.
After so setting up, when the rainwater permeates to the concrete layer 4 that permeates water through the brick layer 5 that permeates water, partial rainwater permeates to drain pipe 6 through the infiltration hole after 8 filter on geotechnological cloth layer, discharges to the concrete layer 4 both sides that permeate water through drain pipe 6 both ends again, can effectively avoid too much rainwater gathering in basic unit 1 and lead to the unstable phenomenon of water permeability pavement structure. The drain pipe 6 that a plurality of intervals set up can effectively increase the displacement to infiltration to 4 interior rainwater on the concrete layer that permeates water to improve the retaining effect of draining of this application.
In order to improve the construction efficiency of this application, as shown in fig. 1-fig. 2, be provided with the location structure who is used for fixing a position drain pipe 6 in the concrete layer 4 that permeates water, specifically, location structure is including setting up constant head tank 9 in the concrete layer 4 that permeates water, and constant head tank 9 is the same with drain pipe 6 arrangement direction and with drain pipe 6 gomphosis adaptation, and constant head tank 9 upper end opening sets up. Therefore, when the permeable concrete layer 4 is constructed, the positioning groove 9 is reserved in the permeable concrete layer 4, the drain pipe 6 wrapped with the geotechnical cloth layer 8 is arranged in the positioning groove 9, the drain pipe 6 can be effectively positioned, and the drain pipe 6 is prevented from being inclined to affect the drainage efficiency.
In order to further improve the drainage efficiency of the drainage pipe 6, as shown in fig. 1-2, the permeable concrete layer 4 is provided with a guide groove 10 at the opening of the upper end of the positioning groove 9, the guide groove 10 is in a flaring shape, and the closing end of the guide groove 10 is in butt joint with the opening end of the positioning groove 9. Thereby the rainwater part among the infiltration concrete layer 4 that permeates water assembles 6 tops of drain pipe as far as under the guide of the concrete layer 4 upper surface that permeates water to the volume of rainwater in the entering drain pipe 6 has been improved, has also improved the drainage efficiency of this application.
During actual construction, as shown in fig. 1-2, a water-permeable asphalt layer 11 may be further disposed between the water-permeable concrete layer 4 and the water-permeable brick layer 5 to fill up uneven portions of the upper surface of the water-permeable concrete layer 4, so as to ensure stable laying of the water-permeable bricks; and the guiding groove 10 is filled to the upper end face of the drain pipe 6 by the permeable asphalt layer 11, meanwhile, an isolation net 12 is arranged between the drain pipe 6 and the permeable asphalt layer 11, and the isolation net 12 is a stainless steel net or a multi-layer plastic net cloth.
Thereby the pitch layer 11 that permeates water further improves the water permeability of this application to can effectively fill the vacancy position of guiding groove 10, the setting of separation net 12 can effectively keep apart geotechnological cloth layer 8 and the pitch layer 11 that permeates water, so that the too much adhesion of the pitch in the pitch layer 11 that permeates water influences geotechnological cloth layer 8's the efficiency of permeating water on geotechnological cloth layer 8.
