Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to an ecological corridor grid conduit permeable road. Background Art

[0003] In order to improve the water permeability of the road surface and build an eco-friendly city, many permeable road construction technologies have emerged recently. For example, permeable concrete is used for road construction, but there are large pores inside and on the surface of permeable concrete. Under load, stress concentration is prone to occur at the tip of the pore, resulting in crack damage and expansion, which is prone to road cracking and surface particle shedding. Some permeable roads also lay grid-shaped permeable conduits in the road surface during construction, and use the permeable conduits to guide the surface water to the deep underground layer, which effectively solves the surface water permeability problem of the road surface.

[0004] Existing grid-duct permeable roads usually have permeable pipes at the base of the road, and use the permeable pipes to discharge rainwater that has penetrated into the road base into the urban drainage network, so that the rainwater can also penetrate into the road base during the discharge process. However, during road construction, the road base is usually compacted and has poor permeability, so the amount of rainwater that penetrates into the road base is relatively limited. Moreover, when there is a large amount of rainfall in a short period of time, the rainwater that has penetrated into the lower layer of the road surface is usually discharged through the permeable pipes in a short time, and the rainwater that can penetrate into the ground is usually less.

DETAILED DESCRIPTION

[0027] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] An embodiment of the ecological corridor grid conduit permeable road of the present invention is as follows Figure 1As shown, from top to bottom, an asphalt surface layer 1, a concrete layer 2, a crushed stone layer 3, an absorption layer 4 and a base soil layer 5 are laid respectively. The materials used and the laying thickness of each structural layer are determined according to the requirements of the engineering design. A conduit grid plate 6 is arranged between the concrete layer 2 and the crushed stone layer 3. The conduit grid plate 6 is a plate-like structure with a plurality of vertically arranged permeable conduits 61. The plurality of permeable conduits 61 are arranged in a grid on the conduit grid plate 6. The permeable conduits 61 are consolidated in the asphalt surface layer 1 and the concrete layer 2, penetrate the asphalt surface layer 1 upwards, and open on the surface of the asphalt surface layer 1, penetrate the concrete layer 2 downwards, and open on the upper surface of the crushed stone layer 3. The rainwater falling on the asphalt surface layer 1 can be guided to the crushed stone layer 3 through the lumen of the permeable conduit 61, so that the asphalt surface layer 1 and the concrete layer 2 have better permeability, thereby eliminating the need to use permeable asphalt and permeable concrete of special structure, and improving the structural strength of the asphalt surface layer 1 and the concrete layer 2.

[0030] The absorption layer 4 is mainly paved with granular materials with smaller diameters such as sandstone and ceramsite, and some ash and soil may be mixed in the sandstone and / or ceramsite to improve the structural stability of the absorption layer 4. A water retaining pipe 41 and a rainwater discharge pipe 42 are arranged in the absorption layer 4, and the water retaining pipe 41 and the rainwater discharge pipe 42 are arranged along the length direction of the road.

[0031] A plurality of water-retaining pipes 41 can be arranged at intervals in the width direction of the road, and a plurality of water-permeable holes 411 are arranged on the pipe wall of the water-retaining pipes 41. The water-retaining pipes 41 can be connected to each other in the length direction of the road to form a long integral pipe, and the two ends of the pipe are closed. A plurality of water-retaining pipes 41 separated from each other can also be arranged in the length direction of the road, and the two ends of each water-retaining pipe 41 are closed. During rainfall, rainwater that penetrates into the gravel layer 3 through the water-permeable conduit 61 penetrates downward into the absorption layer 4, and while further penetrating into the base soil layer 5, a portion of the rainwater enters the water-retaining pipe 41 through the water-permeable holes 411, so that when the rainfall is large, the water-retaining pipe 41 can be used to store more rainfall, improve the water-retaining capacity of the roadbed, and reduce the amount of rainwater discharged. After the rainfall stops, the rainwater in the water-retaining pipe 41 can seep out through the water-permeable holes 411 and be discharged into the base soil layer 5 to replenish the water content in the soil.

[0032] The height of the rainwater discharge pipe 42 is higher than that of the water retaining pipe 41, and the rainwater discharge pipe 42 is connected to the water retaining pipe 41. When the water retaining pipe 41 is full of rainwater and the rainwater in the absorption layer 4 continues to penetrate through the water permeable holes 411, the rainwater in the water retaining pipe 41 will flow into the rainwater discharge pipe 42. The rainwater discharge pipe 42 is connected to the municipal rainwater discharge pipe network, and the rainwater in the rainwater discharge pipe 42 is discharged through the municipal rainwater discharge pipe network, ensuring that excessive rainwater can be discharged in time after a large amount of rainfall to prevent road waterlogging.

[0033] In some embodiments of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 and Figure 2 As shown, the conduit grid plate 6 includes a water-permeable conduit 61 and a grid bottom plate 62. The grid bottom plate 62 is configured as a flat plate, and a plurality of conduit through holes 621 penetrating the grid bottom plate 62 are provided on the grid bottom plate 62, and the plurality of conduit through holes 621 are arranged in a grid shape on the grid bottom plate 62.

[0034] The lower end of the water-permeable conduit 61 is inserted into the conduit through hole 621 and fixedly connected to the grid bottom plate 62. The upper end of the water-permeable conduit 61 extends upward, so that the water-permeable conduit 61 and the grid bottom plate 62 are perpendicular to each other. The length of the water-permeable conduit 61 is equal to the sum of the asphalt surface layer 1 and the concrete layer 2, ensuring that the upper end of the water-permeable conduit 61 is flush with the surface of the asphalt surface layer 1.

[0035] A plurality of grid-shaped cross-seepage grooves 622 are arranged vertically and horizontally on the bottom surface of the grid bottom plate 62, and each seepage groove 622 is connected to a plurality of conduit holes 621 in the horizontal direction or the vertical direction, so that each conduit hole 621 is located at the intersection of a horizontal seepage groove 622 and a vertical seepage groove 622. Rainwater that penetrates under the grid bottom plate 62 through the permeable conduit 61 can penetrate into a larger range on the upper surface of the gravel layer 3 along the seepage grooves 622, ensuring that the rainwater penetrates into the interior of the gravel layer 3 faster.

[0036] In a preferred embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 and Figure 2 As shown, the water-permeable conduit 61 is formed by connecting a fixed conduit 611 and an elastic conduit 612. The fixed conduit 611 is located in the concrete layer 2 and is mutually fixed with the concrete layer 2. The lower end of the fixed conduit 611 extends out of the concrete layer 2, is inserted into the conduit through hole 621, and is fixedly connected to the grid bottom plate 62.

[0037] A fixed wing plate 613 is provided at the middle upper part of the elastic conduit 612, and the elastic conduit 612 passes through the fixed wing plate 613 and is fixedly connected to the fixed wing plate 613. The elastic conduit 612 is arranged in the asphalt surface layer 1, the upper end is flush with the upper surface of the asphalt surface layer 1, and the lower end is inserted into the tube cavity of the fixed conduit 611.

[0038] The fixed wing plate 613 can improve the stability of the connection between the elastic conduit 612 and the asphalt surface layer 1, and prevent the two from sliding against each other. Since the asphalt surface layer 1 has good elasticity and is easily elastically deformed, the lower end of the elastic conduit 612 is inserted into the tube cavity of the fixed conduit 611 so that the elastic conduit 612 and the fixed conduit 611 can slide against each other, so that when the asphalt surface layer 1 is elastically deformed, the length of the water-permeable conduit 61 can change accordingly, ensuring that the top of the elastic conduit 612 is flush with the upper surface of the asphalt surface layer 1.

[0039] In one embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 As shown, a drainage pipeline 7 is also provided in the ecological corridor grid conduit permeable road of the present invention, and the drainage pipeline 7 includes a drainage well 71 and a drainage connecting pipe 72. Curbstones 11 are provided on both sides of the asphalt surface layer 1, and the curbstones 11 are used to separate the road surface and the auxiliary structure.

[0040] The drainage well 71 is arranged on both sides of the asphalt surface layer 1, near the curb 11. Usually, the drainage well 71 is formed by pouring concrete material, and the road surface passes through the asphalt surface layer 1, the concrete layer 2 and the crushed stone layer 3 into the absorption layer 4. The drainage connecting pipe 72 is arranged horizontally in the absorption layer 4, and is connected between the drainage well 71, the water retaining pipe 41 and the rainwater discharge pipe 42.

[0041] The drainage well 71 can quickly and massively guide the accumulated water on the asphalt surface layer 1 into the water retaining pipe 41 and the rainwater discharge pipe 42 when the rainfall is heavy, thereby reducing the accumulated water on the asphalt surface layer 1. A drainage grid can be set at the entrance of the drainage well 71, which can prevent large debris on the road surface from entering the drainage well 71 and causing blockage of the drainage pipeline.

[0042] In a preferred embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 As shown, the ecological corridor grid conduit permeable road of the present invention is provided with two road surfaces in different traffic directions, and an ecological isolation zone 8 is provided between the two road surfaces in different traffic directions.

[0043] The ecological isolation zone 8 is provided with an ecological soil layer 81, an infiltration water chamber 82 and a water storage chamber 83 from top to bottom. The ecological soil layer 81 is used to plant ecological plants, which is conducive to maintaining the ecological effect of the road. A water-permeable fiber 811 is provided at the bottom of the ecological soil layer 81. The water-permeable fiber 811 is made of a fibrous material with a large number of capillaries inside. The water-permeable fiber 811 passes through the holes provided on the top wall of the infiltration water chamber 82 and enters the infiltration water chamber 82, extending to the bottom of the infiltration water chamber 82. When water is stored in the infiltration water chamber 82, the water in the infiltration water chamber 82 can penetrate into the ecological soil layer 81 along the water-permeable fiber 811, and be absorbed by the ecological plants planted in the ecological soil layer 81, so as to meet the growth needs of the ecological plants.

[0044] A connecting water pipe 821 is provided between the infiltration water chamber 82 and the water storage chamber 83, the upper end of the connecting water pipe 821 is opened at the upper part of the infiltration water chamber 82, and the lower end is opened at the bottom of the water storage chamber 83. When the amount of water stored in the infiltration water chamber 82 is large, the water in the infiltration water chamber 82 can flow into the water storage chamber 83 through the opening at the top of the connecting water pipe 821, limiting the amount of water stored in the infiltration water chamber 82, thereby preventing the water content in the ecological soil layer 81 from being too high, affecting the normal growth of ecological plants.

[0045] The side wall of the water storage chamber 83 is connected to the drainage connecting pipe 72. On the one hand, the rainwater in the drainage well 71 can be used to store water in the water storage chamber 83 to meet the irrigation needs of ecological plants; on the other hand, more rainwater can be stored during heavy rainfall to further improve the water retention capacity of the roadbed.

[0046] In a further preferred embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 and Figure 3 As shown, a hinged cover plate 831 is provided at the opening of the drainage connection pipe 72 in the water storage chamber 83. Specifically, a hinged support shaft is provided on the inner side wall of the water storage chamber 83, and the upper part of the hinged cover plate 831 is hinged on the hinged support shaft, so that the hinged cover plate 831 covers the opening of the drainage connection pipe 72 under the action of gravity in a natural state, so that the opening of the drainage connection pipe 72 is in a closed state.

[0047] An elastic sealing layer 832 is disposed on the side surface of the hinged cover plate 831 facing the drain connection pipe 72, and the setting range of the elastic sealing layer 832 covers the entire opening of the drain connection pipe 72. In a natural state, the hinged cover plate 831 presses the elastic sealing layer 832 against the opening of the drain connection pipe 72 to ensure the sealing of the opening of the drain connection pipe 72 and prevent the water in the water storage chamber 83 from flowing out through the drain connection pipe 72.

[0048] In a specific embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 and Figure 3 As shown, a drainage float 822 is provided in the permeation water chamber 82, and a cover plate traction line 823 is connected to the drainage float 822. The cover plate traction line 823 is made of nylon material. A traction rope passing hole is provided on the partition between the permeation water chamber 82 and the water storage chamber 83, and an elastic silicone tube is fixed in the traction rope passing hole. The cover plate traction line 823 passes through the tube cavity of the elastic silicone tube and enters the water storage chamber 83, and is connected to the traction bending plate at the lower end of the hinged cover plate 831.

[0049] The cover plate traction line 823 passes through the elastic silicone tube and enters the water storage chamber 83, so that the cover plate traction line 823 can slide in the elastic silicone tube, while keeping the elastic silicone tube cavity closed, preventing the water in the infiltration water chamber 82 from flowing into the water storage chamber 83. The length of the cover plate traction line 823 is set so that when the water level in the infiltration water chamber 82 is flush with the top of the connecting water pipe 821, the cover plate traction line 823 can just pull the hinged cover plate 831 to rotate, open the opening of the drainage connection pipe 72, so that the water in the water storage chamber 83 can be discharged through the drainage connection pipe 72, and prevent the excessive amount of water stored in the infiltration water chamber 82. The setting of the lower end of the hinged cover plate 831 pulling the bending plate can, on the one hand, increase the pressure of the hinged cover plate 831 on the opening of the drainage connection pipe 72, and on the other hand, increase the torque of the cover plate traction line 823 pulling the hinged cover plate 831 to rotate.

[0050] In another embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 1 , Figure 4 and Figure 5 As shown, the ecological corridor grid conduit permeable road of the present invention is also provided with an ecological irrigation mechanism 9. The ecological irrigation mechanism 9 includes an elastic air chamber 91 and an air guide pipe 92. The elastic air chamber 91 can be any device that can agitate the flow of gas through the elastic deformation of the side wall. The elastic air chamber 91 is arranged between the asphalt surface layer 1 and the concrete layer 2. When a vehicle travels on the asphalt surface layer 1, the elastic deformation of the asphalt surface layer 1 can cause the side wall of the elastic air chamber 91 to produce elastic deformation, driving the gas in the elastic air chamber 91 to enter and exit the elastic air chamber 91.

[0051] The air guide pipe 92 is interconnected by a tee pipe, or the air blast pipe 921, the air inlet pipe 922 and the air outlet pipe 923 are directly connected to each other. The air blast pipe 921, the air inlet pipe 922 and the air outlet pipe 923 usually use small diameter stainless steel pipes, or copper pipes, to reduce the elastic deformation of the air blast pipe 921, the air inlet pipe 922 and the air outlet pipe 923, and prevent the pipes from closing under external pressure.

[0052] The air blast pipe 921 is arranged between the asphalt surface layer 1 and the concrete layer 2, and can also be arranged in the concrete layer 2. One end of the air blast pipe 921 is connected to the elastic air blast chamber 91, and the other end passes through the side wall of the drainage well 71 and enters the drainage well 71. The air inlet pipe 922 and the air outlet pipe 923 are arranged in the drainage well 71, and are usually fixed on the side wall of the drainage well 71. An air inlet check valve 924 is arranged at the end of the air inlet pipe 922, and an air outlet check valve 925 is arranged in the air outlet pipe 923. When the elastic air blast chamber 91 discharges gas, the air inlet check valve 924 is closed and the air outlet check valve 925 is opened, and the gas flows out through the air outlet pipe 923; when the elastic air blast chamber 91 inhales gas, the air inlet check valve 924 is opened and the air outlet check valve 925 is closed, and the gas in the drainage well 71 enters the elastic air blast chamber 91 through the air inlet pipe 922.

[0053] The air outlet pipe 923 is connected to the water storage chamber 83. The gas flowing out through the air outlet pipe 923 enters the water storage chamber 83, which increases the air pressure in the water storage chamber 83, driving the rainwater stored in the water storage chamber 83 to enter the infiltration water chamber 82 through the connecting water pipe 821, thereby irrigating the ecological plants planted in the ecological soil layer 81.

[0054] In a preferred embodiment of the ecological corridor grid conduit permeable road of the present invention, as Figure 4 As shown, the elastic air chamber 91 includes an air chamber substrate 911, an elastic cover plate 912 and a return spring 913. An air chamber groove 914 is provided on the upper side of the air chamber substrate 911, and the elastic cover plate 912 is provided in the air chamber groove 914. The peripheral portion of the elastic cover plate 912 is in contact with the bottom wall of the air chamber groove 914, and there is a gap of 1-2 mm between the middle portion of the elastic cover plate 912 and the bottom wall of the air chamber groove 914. A sealed air chamber with a thickness of 1-2 mm is formed between the elastic cover plate 912 and the air chamber substrate 911. The air chamber with a thickness of 1-2 mm can reduce the deformation of the elastic cover plate 912, ensure the structural stability of the asphalt surface layer 1, and reduce the vibration caused by the deformation of the asphalt surface layer 1 when a vehicle passes.

[0055] A conduit connection hole is provided on one side wall of the elastic cover plate 912 and the air chamber substrate 911, and one end of the air pipe 921 passes through the conduit connection hole and is connected to the air chamber. When the elastic cover plate 912 is elastically deformed under the action of external pressure, the gas in the air chamber flows into or out of the air chamber through the air pipe 921.

[0056] A spring mounting hole 915 is provided in the middle of the bottom wall of the air inflation groove 914, and the lower end of the reset spring 913 is installed in the spring mounting hole 915, and the upper end is supported on the elastic cover plate 912.
