[0019] The present application is described in more detail by the following specific examples. Other advantages and effects of the present application can be easily understood by those skilled in the art from the disclosure of this specification. The present application can also be implemented or applied by different specific embodiments, and the details in this specification can be modified or changed based on different views and applications without departing from the spirit of the present application.

[0020] The mountain road capable of self-purifying rainwater will be described in further detail below in combination with the accompanying drawings and specific embodiments.

[0021] Referring to Figures 1-5 The mountain road capable of self-purifying rainwater comprises: A road body, a surface of the road body being sloped from a side close to a mountain to a side away from the mountain; A water collecting tank arranged along a length direction of the road body and connected to the side close to the mountain of the road body, for collecting mountain runoff; A plurality of purification channels 3 are arranged along the length direction of the road body, each of the purification channels 3 is vertically arranged along the length direction of the road body, and each of the purification channels 3 is in communication with the water collecting groove. A plurality of filter cartridges are correspondingly arranged in the plurality of purification channels 3, and the water introduced into the purification channels 3 is purified by the filter cartridges.

[0022] Through the above arrangement, when it rains, rainwater flows down the mountain to form mountain runoff. Based on the flow direction of the mountain runoff, the mountain runoff automatically flows into the water collecting groove and enters the purification channels 3. In the process of flowing, the water is purified by the filter cartridges in the purification channels 3, and finally is orderly discharged.

[0023] Specifically, a drainage ditch is arranged on the side of the road body away from the mountain, and the drainage ditch is in communication with the plurality of purification channels 3.

[0024] By arranging the drainage ditch, the water purified by the purification channels 3 can be orderly discharged.

[0025] Specifically, the slope of the road body is 1.5%.

[0026] Preferably, the purification channels 3 are arranged downward from the side close to the mountain to the side away from the mountain.

[0027] By arranging the purification channels 3 downward, the water flowing into the purification channels 3 flows from the side close to the mountain to the side away from the mountain, avoiding the accumulation of water flow in the purification channels 3.

[0028] Preferably, the water collecting groove comprises an L-shaped plate 7, the horizontal plate of the L-shaped plate 7 is connected to the side of the road body close to the mountain, the vertical plate of the L-shaped plate 7 is provided with a plurality of first water inlet holes along the length direction of the road body, the bottom elevation of the first water inlet hole is higher than the bottom elevation of the purification channel 3, and each of the first water inlet holes is connected with a first filter screen 8.

[0029] By arranging the first water inlet hole and connecting the first filter screen 8, the mountain runoff can be preliminarily filtered and purified.

[0030] By limiting the bottom elevation of the first water inlet hole to be higher than the bottom elevation of the purification channel 3, the water flowing into the water collecting groove is prevented from flowing back.

[0031] Specifically, the water collecting groove further comprises a water collecting groove cushion layer 5 and a water collecting groove base layer 6 connected to the top of the water collecting groove cushion layer 5, and the horizontal plate of the L-shaped plate 7 is connected to the top of the water collecting groove base layer 6.

[0032] By setting the gutter pad 5 and the gutter base 6, the L-shaped plate 7 is provided with a stable connection foundation.

[0033] Preferably, the top of the gutter is connected with a cover plate 9, one end of which is placed on the top of the vertical plate of the L-shaped plate 7, and the other end is connected to the corresponding side of the road body.

[0034] By setting the cover plate 9, it is avoided that the gravel falling from the mountain enters the gutter, thereby avoiding blocking the drainage and providing protection.

[0035] Preferably, a plurality of second water inlets are provided on the top of the cover plate 9 along the length direction, and each of the second water inlets is connected with a second filter screen 10.

[0036] When the water level of the mountain runoff caused by heavy rainfall is higher than the cover plate 9, the second water inlet and the second filter screen 10 can also preliminarily filter and purify the mountain runoff. The road pad 1; The concrete layer 2 is poured on the top of the road pad 1, and the purification channel 3 is provided in the concrete layer 2; The two rows of curb stones 4 are connected to the opposite sides of the top of the concrete layer 2, the cover plate 9 is connected to the corresponding curb stone 4, and the top of the curb stone 4 is higher than the top of the cover plate 9.

[0037] By setting the curb stone 4, the water is blocked, and the mountain runoff is prevented from directly flowing from the top of the road body.

[0038] Specifically, the road body further comprises a surface layer, which is laid on the top of the concrete layer 2 and between the two rows of curb stones 4.

[0039] Specifically, a row of curb stones 4 far away from the mountain is provided with a drainage hole.

[0040] By providing the drainage hole, the rainwater on the road body can be easily drained.

[0041] Specifically, the cover plate 9 is detachably connected with the corresponding row of curb stones 4, one side of the cover plate 9 is connected with a plug, and the curb stone 4 is provided with a slot for inserting the plug.

[0042] By setting the cover plate 9 in a detachable connection form, when the rainfall is too large and the drainage demand is large, the cover plate 9 can be easily removed, and the mountain runoff and rainwater can directly enter the gutter.

[0043] Preferably, the filter core comprises: The strip-shaped steel wire cage 11 is detachably inserted into the corresponding purification channel 3; Water-permeable geotextile 12, connected in the middle of the strip-shaped steel wire cage 11, for separating the space in the strip-shaped steel wire cage 11 into two independent spaces; Gravel 13, filled in one of the independent spaces, for slowing down the flow rate of water entering the purification channel 3; Activated carbon 14, filled in the other independent space, for purifying water entering the purification channel 3.

[0044] By setting the filter core in a detachable form, the internal activated carbon 14 can be replaced regularly to maintain the purification effect; in addition, when the precipitation amount is too large and the drainage demand is large, the filter core can be removed, and the purification channel 3 can be directly used as a drainage channel for drainage.

[0045] Specifically, in the inserted state of the filter core, one end of the strip-shaped steel wire cage 11 filled with gravel 13 faces the water collecting tank, and the other end filled with activated carbon 14 is away from the water collecting tank.

[0046] Through the above arrangement, it is ensured that the water entering the purification channel 3 from the water collecting tank will first slow down the flow rate by the gravel 13, and then be purified by the activated carbon 14, so that it can be fully purified by the activated carbon 14, thereby improving the purification effect.
