Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a mountain road that can self-purify rainwater. Background Technology

[0002] Common mountain roads typically consist of the main road structure, slope protection facilities, drainage facilities, and ecological restoration facilities. During the design and construction process, more emphasis is often placed on the safety and stability of the road, while the impact on the environment is easily overlooked. In particular, the road obstructs surface runoff on the slope, and the municipal pipe network in mountainous areas is not perfect. Water is often diverted and discharged through intercepting ditches and drainage ditches, which can easily lead to the following problems: First, there are more pollutants on the road surface, and the initial rainwater runoff is seriously polluted. Direct discharge can easily have adverse effects on the environment. Second, the number of existing road pipes or culverts is limited and the flow rate is small, which can easily cause overflow and damage to the road structure. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art, provide a mountain road that can self-purify rainwater, automatically divert mountain runoff, purify it during the flow, and discharge it in an orderly manner, so as to avoid mountain runoff from polluting the environment.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is a self-purifying rainwater mountain road, comprising: The road body, the surface of which slopes from the side closer to the mountain to the side farther away from the mountain; A water collection trough is installed along the length of the road body and is continuously connected to the side of the road body near the mountain to collect mountain runoff; Multiple purification channels are spaced apart along the length of the road body. Each purification channel is opened through the road body along a length perpendicular to the road body. Each purification channel is connected to the water collection tank and is used to introduce water from the water collection tank into the purification channel. Multiple filter cartridges are inserted one-to-one into multiple purification channels to purify the water introduced into the purification channels.

[0005] A further improvement of the self-purifying rainwater mountain road of the present invention is that the purification channel is inclined downward from the end closer to the mountain to the end farther away from the mountain.

[0006] A further improvement of the self-purifying rainwater mountain road of the present invention is that the water collection trough includes an L-shaped plate, the horizontal plate of the L-shaped plate is connected to the side of the road body near the mountain, and a plurality of first water inlets are spaced apart on the vertical plate of the L-shaped plate along the length of the road body. The bottom elevation of the first water inlets is higher than the bottom elevation of the purification channel, and a first filter screen is connected to each first water inlet.

[0007] A further improvement of the self-purifying rainwater mountain road of the present invention is that the top of the water collection trough is connected to a cover plate, one end of which rests on the top of the vertical plate of the L-shaped plate, and the other end is connected to the corresponding side of the road body.

[0008] A further improvement of the self-purifying rainwater mountain road of the present invention is that the top of the cover plate is provided with a plurality of second water inlets spaced apart along the length direction, and each second water inlet is connected to a second filter screen.

[0009] A further improvement of the self-purifying rainwater mountain road of the present invention is that the road body comprises: Road subbase; A concrete layer is poured on top of the road subbase, and the purification channel is opened within the concrete layer; Two rows of curb stones are connected along their length to opposite sides of the top of the concrete layer. The cover plate is connected to the curb stones on the corresponding sides, and the top elevation of the curb stones is higher than the top elevation of the cover plate.

[0010] A further improvement of the self-purifying rainwater mountain road of the present invention is that the filter element comprises: A strip-shaped wire cage is detachably inserted into the corresponding purification channel; A permeable geotextile is connected to the middle of the strip wire cage to divide the space inside the strip wire cage into two independent spaces. Gravel is filled in one of the separate spaces to slow the flow rate of water just entering the purification channel; Activated carbon is filled in another separate space to purify the water entering the purification channel.

[0011] Compared with the prior art, the advantages of the present invention are: By setting up water collection channels and purification channels, the runoff from the mountain is diverted and purified during the diversion process before being discharged in an orderly manner, thus preventing the runoff from overflowing and damaging the road structure and polluting the environment.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0020] The following detailed description of the self-purifying rainwater mountain road of the present invention, with reference to the accompanying drawings and specific embodiments, is provided in further detail.

[0021] Please see Figures 1-5 As shown, self-purifying mountain roads include: The road body, the surface of which slopes from the side closer to the mountain to the side farther away from the mountain; A water collection trough is installed along the length of the road body and is connected to the side of the road body closest to the mountain to collect mountain runoff; Multiple purification channels 3 are spaced apart along the length of the road body. Each purification channel 3 is opened through the road body along the length perpendicular to the road body. Each purification channel 3 is connected to the water collection tank and is used to introduce water from the water collection tank into the purification channel 3. Multiple filter cartridges are inserted one-to-one into multiple purification channels 3 to purify the water introduced into the purification channel 3.

[0022] With the above setup, when precipitation occurs, rainwater will flow down the mountain to form mountain runoff. Based on the direction of the mountain runoff, the mountain runoff will automatically flow into the water collection tank and enter the purification channel 3. During the flow, it will be purified by the filter element in the purification channel 3 and finally discharged in an orderly manner.

[0023] Specifically, a drainage ditch is constructed along the side of the road that is relatively far from the mountain, and the drainage ditch is connected to multiple purification channels 3.

[0024] By creating this drainage ditch, it is easy to discharge the water purified through the purification channel 3 in an orderly manner.

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

[0026] Preferably, the purification channel 3 is inclined downwards from the end closest to the mountain to the end furthest from the mountain.

[0027] By tilting the purification channel 3, the water entering the purification channel 3 flows from the end closer to the mountain to the end farther away from the mountain, thus preventing water from accumulating inside the purification channel 3.

[0028] Preferably, the water collection trough includes an L-shaped plate 7, the horizontal plate of which is connected to the side of the road body near the mountain, and the vertical plate of the L-shaped plate 7 is provided with a plurality of first water inlets spaced apart along the length of the road body. The bottom elevation of the first water inlets is higher than the bottom elevation of the purification channel 3, and a first filter screen 8 is connected to each of the first water inlets.

[0029] By opening the first water inlet and connecting the first filter screen 8, it is convenient to perform preliminary filtration and purification of the mountain runoff.

[0030] By limiting the bottom elevation of the first water inlet to be higher than the bottom elevation of the purification channel 3, backflow of water entering the water collection tank is prevented.

[0031] Specifically, the water collection tank also includes a water collection tank pad 5 and a water collection tank base layer 6 connected to the top of the water collection tank pad 5, and the horizontal plate of the L-shaped plate 7 is connected to the top of the water collection tank base layer 6.

[0032] By setting the water collection tank pad 5 and the water collection tank base layer 6, a stable connection foundation is provided for the L-shaped plate 7.

[0033] Preferably, the top of the water collection trough is connected to a cover plate 9, one end of which rests 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 installing this cover plate 9, debris sliding down the mountain is prevented from entering the water collection trough, thus preventing drainage blockage and providing protection.

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

[0036] When heavy rainfall causes the water level of the runoff to rise above the cover plate 9, the second inlet and the second filter screen 10 can also perform preliminary filtration and purification of the runoff. Preferably, the road body includes: Road subbase 1; Concrete layer 2 is poured on top of the road subbase 1, and the purification channel 3 is opened inside the concrete layer 2. Two rows of curb stones 4 are connected along the length of the concrete layer 2 to opposite sides on the top. The cover plate 9 is connected to the curb stones 4 on the corresponding side. The top elevation of the curb stones 4 is higher than the top elevation of the cover plate 9.

[0037] By setting this curbstone 4, water can be blocked, preventing runoff from flowing directly from the top of the road body.

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

[0039] Specifically, drainage holes are spaced apart on a row of curb stones 4 that are relatively far from the mountain.

[0040] By opening this drainage hole, it is easy to drain rainwater from the road surface.

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

[0042] By setting the cover plate 9 to a detachable connection, it is easy to remove the cover plate 9 when the rainfall is too heavy and the drainage demand is high, so that the mountain runoff and rainwater can directly enter the water collection trough.

[0043] Preferably, the filter element includes: The strip wire cage 11 is detachably inserted into the corresponding purification channel 3; The permeable geotextile 12 is connected to the middle of the strip wire cage 11 and is used to divide the space inside the strip wire cage 11 into two independent spaces. Gravel 13 is filled in one of the separate spaces to slow the flow of water as it enters the purification channel 3. Activated carbon 14 is filled in another separate space to purify the water entering the purification channel 3.

[0044] By making the filter element removable, it is easy to replace the internal activated carbon 14 regularly to maintain the purification effect. In addition, when the rainfall is too heavy and the drainage demand is large, the filter element can be removed and the purification channel 3 can be directly used as a drainage channel for water discharge.

[0045] Specifically, when the filter element is inserted, the end of the wire mesh cage 11 filled with gravel 13 faces the water collection tank, while the end filled with activated carbon 14 is away from the water collection tank.

[0046] With the above settings, the water entering the purification channel 3 from the water collection tank will first have its flow rate slowed down 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.
