Detailed Description

The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.

As shown in fig. 1 and 2, the roadbed structure convenient for discharging water accumulated inside the roadbed of the embodiment comprises: road bed 100 and drainage channel 200, road bed 100 including locate waterproof layer 101 on soil layer 104 and locate drainage pitch layer 103 on the waterproof layer 101, drainage channel 200's side is equipped with filter screen 201, drainage channel 200 is equipped with filter screen 201's side and connects road bed 100.

During construction, firstly, a waterproof layer 101 is paved on a soil layer 104, then a water-filtered asphalt layer 103 is paved on a waterproof layer 10, then one side of a drainage channel 200 provided with a filter screen 201 is connected to the side of the roadbed 100, the waterproof layer 101 can prevent water from penetrating and penetrating, when raining, rainwater falls onto the waterproof layer 101 after passing through the water-filtered asphalt layer 103, then flows into the drainage channel 200 on two sides through the filter screen 201, and the filter screen 201 can prevent sundries in the drainage channel 200 from attaching to the side surface of the water-filtered asphalt layer 103 and affecting drainage of the rainwater.

In the roadbed structure convenient to discharge the accumulated water in the roadbed of the embodiment, in order to have a better drainage effect, the drainage channels 200 of the embodiment are specifically two and are respectively arranged on two sides of the roadbed 100, in other embodiments, only one drainage channel 200 can be arranged, and the other side of the roadbed 100 is plugged by concrete.

In the roadbed structure convenient for discharging water accumulated in the roadbed according to the embodiment, because two drainage channels 200 are provided, the waterproof layer 101 is arranged into an inverted V shape, the horizontal height of the middle part of the waterproof layer is the highest, the horizontal positions of the positions where the two sides of the waterproof layer are connected with the drainage channels 200 are the lowest, so that water reaching the waterproof layer 101 can flow into the drainage channels 200 towards the two sides more quickly, and in other embodiments, if only one drainage channel 200 exists, the section of the waterproof layer 101 is a straight line with an inclined horizontal plane, and the lowest point of the waterproof layer 101 is connected with the drainage channel 200.

In the roadbed structure convenient to discharge the inside ponding of roadbed of this embodiment, roadbed 100 is still including locating the filter material structural layer 102 between waterproof layer 101 and drainage pitch layer 103, filter material structural layer 102 lays on waterproof layer 101, because waterproof layer 101 sets up to "V" shape of falling, the lower surface of filter material structural layer 102 in its contact also is "V" shape of falling, and simultaneously, in order to have better flowing water effect, the upper surface that filter material structural layer 102 is connected with drainage pitch layer 103 also is "V" shape of falling, and the inclination of the upper surface of filter material structural layer 102 is less than the inclination of lower surface, the lower surface slope of filter material structural layer 102 sets up, when making and passing through drainage pitch layer 103 and filter material structural layer 102 contact the upper surface of waterproof layer 101 with the rainwater, to both sides removal, and then discharge from the both sides of filter material structural layer 102 and enter into the escape canal 2 of both sides because of the lower surface inclination of filter material structural layer 102 sets up greatly, the speed of rainwater drainage has been accelerated.

In the roadbed structure convenient to discharge the accumulated water in the roadbed of the embodiment, two side walls of the drainage channel 200 are higher and lower, and the lower side wall is connected with the roadbed 100, so that a plurality of filter screens 201 can be arranged on the side surface of the filter material structure layer 102, and impurities in the drainage channel 2 are prevented from being attached to the side surface of the filter material structure layer 102.

As shown in fig. 3, in the roadbed structure convenient for discharging water accumulated in the roadbed of the present embodiment, a plurality of support columns 203 are provided on the side wall of the drainage channel 200 connected to the roadbed 100, a plurality of cover plate grilles 202 are provided on the top of the support columns 203 and the top of the outer wall of the higher side of the drainage channel 200, and two pairs of the cover plate grilles 202 are abutted against each other, a plurality of support columns 203 are provided for supporting the plurality of cover plate grilles 202, and impurities are prevented from entering the drainage channel 2 through the cover plate grilles 202 on the drainage channel 200, thereby blocking the drainage channel 2.

As shown in fig. 4, in the roadbed structure convenient to discharge inside ponding of roadbed of this embodiment, spout 204 has all been seted up to the both sides of support column 203, and equal sliding connection has draw runner 205 on the inner wall of spout 204, filter screen 201 fixed connection is between two corresponding draw runners 205, a plurality of support columns 203 can also make things convenient for draw runner 205 of filter screen 201 both sides to slide into spout 204 on the support column 203 lateral wall, carry on spacingly to the position of filter screen 201, the convenience is dismantled and is cleared up filter screen 201 simultaneously.

The working principle of the embodiment is as follows: because the cross section of the waterproof layer 101 is inverted V-shaped, when rainwater contacts the upper surface of the waterproof layer 101 through the water-filtered asphalt layer 103 and the filter material structure layer 102, the rainwater moves towards the direction with lower horizontal heights at two sides and enters the drainage channels 200 at two sides through the filter screen 201, and impurities in the drainage channels 200 are prevented from attaching to the side surfaces of the filter material structure layer 102 through the filter screen 201 to affect the drainage of the rainwater; through the plurality of supporting columns 203, on one hand, the plurality of cover plate grids 202 can be supported, the sliding strips 205 on the two sides of the filter screen 201 can conveniently slide into the sliding grooves 204 on the side walls of the supporting columns 203, the position of the filter screen 201 is limited, and meanwhile, the filter screen 201 can be conveniently detached and cleaned; when the rainwater is great, because of the lower surface inclination of filter material structural layer 102 sets up great, rainwater exhaust speed has been accelerated, need not increase the construction degree of difficulty simultaneously, only need adjust the cross-flow during surface construction on soil layer 104, thereby the cross-slope angle of waterproof layer 101 has been increased, make the water that filters down from filter material structural layer 102 because the cross-slope angle of waterproof layer 101 is great, be convenient for more flow from both sides and then filter out, the cross-flow of the upper surface of filter material structural layer 102 is unchangeable simultaneously, can not increase the thickness of drainage pitch layer 103, and then can not increase the quantity of pitch, increase cost.

The roadbed structure convenient to discharge the inside ponding of roadbed of this embodiment can avoid drainage channel 200 to block up when not increasing pitch quantity, material cost, avoids drainage channel 200's debris to adhere to on the side of roadbed 100 simultaneously, and filter material structural layer 102 lower surface inclination angle sets up great for rainwater exhaust rate, has effectively ensured drainage efficiency, has avoided roadbed 100 ponding.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
