Description

Technical Field

[0001] The present invention relates to the technical field of frozen soil slope maintenance, and particularly relates to a frozen soil slope protection structure. Background Art

[0002] The soil in the frozen soil area usually contains a large amount of water and freezes under low-temperature conditions to form ice soil with special physical properties. The frozen soil will form a natural slope structure. The seasonal change of temperature will have an important impact on the stability of the slope. The frozen soil layer will be hard in winter, while in summer, the direct sunlight on the slope surface will cause the frozen soil inside the slope to thaw. After thawing, the water flows inside the slope, making the soil become soft, and the soil strength will be significantly reduced, easily leading to slope instability and thus resulting in the risk of landslides. It is necessary to cool the slope through artificial intervention to avoid large temperature differences in the slope due to seasonal changes.

[0003] The existing technology is to set a number of anchor rods and heat pipes used in cooperation with the anchor rods on the frozen soil slope. The heat pipes and anchor rods are driven into the frozen soil slope. The heat pipes work in winter to release the heat inside the frozen soil slope to the outside of the frozen soil slope, realizing the cooling of the frozen soil slope. However, in this method, the heat pipes can only cool the local area of the frozen soil slope, and the cooling range is small, making it difficult to ensure an effective cooling effect. Summary of the Invention

[0004] Aiming at the technical problems existing in the background art, the purpose of the present invention is to provide a frozen soil slope protection structure that can adjust the temperature of the protection structure, keep the slope position at a low temperature regardless of how the air temperature changes, and prevent the frozen soil from melting.

[0006] A frozen soil slope protection structure, the protection structure includes a temperature control component, an upper support structure arranged at the upper end of the slope surface, and a lower support structure arranged at the lower end of the slope surface. The temperature control component is arranged between the upper support structure and the lower support structure, and the temperature control component is connected to the slope inclined surface. There is an overhead area between the temperature control component and the slope, and the air flow passes through the overhead area to lower the temperature of the slope. The lower support structure includes a support member and a heat exchange pipe inserted into the slope. One end of the lower support structure is provided with a drainage ditch for draining water.

[0007] Preferably, the upper support structure and the support member adopt a cage-shaped structure, and a number of gravels are arranged inside the upper support structure, and a number of gravels are arranged inside the support member.

[0008] Preferably, the temperature control component includes a support frame and side plates detachably arranged on both sides of the support frame. The support frame is provided with a card slot, and the side plates are provided with convex blocks. The convex blocks extend into the card slot to connect the support frame and the side plates.

[0017] In the present invention, the protection structure supports on the slope, and a number of ventilation pipes are arranged in the protection structure. When it is in the cold season, the outside cold air can convect through the ventilation pipes to keep the slope at a low temperature and take away the heat of the internal frozen soil. At the same time, in the warm season, the air door is closed to form an air insulation layer to prevent the frozen soil from melting.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] Embodiment

[0030] As Figures 1-8As shown in the figure, a protection structure for frozen soil slopes includes a temperature control component, an upper support structure 2 arranged at the upper end of the slope surface of slope 1, and a lower support structure 3 arranged at the lower end of the slope surface of slope 1. The temperature control component is arranged between the upper support structure 2 and the lower support structure 3. The lower support structure 3 includes a support member 31 and a heat exchange pipe 32 inserted into slope 1. When the temperature in slope 1 changes, part of the heat can be dissipated from the position of the heat exchange pipe 32. The upper support structure 2 can compact the upper end position of the slope to prevent water from flowing in the soil, thereby affecting the quality of the overall slope. The lower support structure 3 can prevent the gravel on slope 1 from falling. The upper support structure 2 and the support member 31 adopt a cage-shaped structure( Figure 8 as shown). And the cage-shaped structure is designed according to the shape of the slope. A number of gravels are arranged inside the upper support structure 2, and a number of gravels are arranged inside the support member 31. Airflow can pass through the cage-shaped structure. The gravels play the role of a thermal semiconductor. In cold weather, the gravels absorb cold energy to keep the support position at a low temperature. When the weather gets warmer, the gravels release the cold energy to slow down the temperature change at the support position. One end of the lower support structure 3 is provided with a drainage ditch 4 for draining water. The surface water around the slope flows into the drainage ditch 4 and flows away along the direction of the drainage ditch 4 to prevent the surface water from seeping into the slope, thereby affecting the quality of the slope.

[0031] As Figures 1-7 shown in the figure, the temperature control component includes a support frame 5 and side plates 6 detachably arranged on both sides of the support frame 5. The support frame 5 is provided with a card slot 51, and the side plate 6 is provided with a convex block 61. The convex block 61 extends into the card slot 51 to connect the support frame 5 and the side plate 6. The convex block 61 and the card slot 51 cooperate to locate the connection position of the side plate 6 and the support frame 5, which is convenient for installation. The side plate 6 is provided with a connection hole Ⅰ 62. The connection hole Ⅰ 62 is arranged at the position of the convex block 61 and penetrates through the convex block 61. The support frame 5 is provided with a connection hole Ⅱ 52. The connection hole Ⅱ 52 is arranged in the card slot 51. When the convex block 61 extends into the card slot 51, the connection hole Ⅰ 62 and the connection hole Ⅱ 52 are aligned. Screwing bolts into the connection hole Ⅰ 62 and the connection hole Ⅱ 52 can fix the side plate 6 on the support frame 5. The side plate 6 is provided with a bolt 63 for plugging into slope 1. The bolt 63 includes a rod body and an anchor head. The rod body and the anchor head are connected by a plugging method. The rod body and the side plate 6 are connected by a detachable connection method. The rod body can pass through the side plate 6 and be connected to the anchor head. The bolt 63 is plugged on slope 1 to fix the entire temperature control component on the slope surface of slope 1.

[0032] As Figures 1-7As shown, a ventilation pipe 7 for adjusting the temperature of the slope 1 is arranged inside the temperature control component. A cross beam is arranged in the middle of the support frame. A number of support grooves 8 are arranged at intervals on the cross beam. The ventilation pipe 7 is connected in the support grooves 8. The ventilation pipe 7 is spliced by a number of U-shaped pipes 71. The pipe head of one U-shaped pipe 71 is aligned and connected with the pipe tail of another U-shaped pipe 71, and the connection position of the U-shaped pipes 71 is located in the support grooves 8. The two ends of the ventilation pipe 7 are respectively connected with an air inlet pipe 72 and an air outlet pipe 73. The air inlet pipe 72 and the air outlet pipe 73 respectively pass through two side plates 6. The air inlet pipe 72 is connected with a fan 74. The fan 74 provides wind power for the ventilation pipe 7 to keep the inside of the ventilation pipe 7 at a low temperature. An adjustable air door 731 is arranged on the air outlet pipe 73. The adjustable air door 731 is rotatably connected at the pipe orifice position of the air outlet pipe 73. When the fan 74 does not provide wind power, the adjustable air door 731 is closed. When the fan 74 provides wind power, the adjustable air door 731 is opened. A channel 81 is arranged in the support groove 8. A clamp 82 for connecting the U-shaped pipe 71 is arranged in the channel 81. When installing the ventilation pipe 7, first loosen the clamp 82 and place it inside the channel 81. The U-shaped pipe 71 passes through the support groove 8 and is placed on the clamp 82, and then tighten the clamp 82. The clamp 82 connects the two U-shaped pipes 71. Whether the clamp 82 or the U-shaped pipe 71 is damaged, just loosen the clamp 82 to replace it. This not only increases the convenience during disassembly and assembly, but also increases the service life of the whole structure. A connection groove 83 is arranged on the support frame 5. The connection groove 83 passes through the whole support frame 5 and passes through a number of channels 81. A support rod 9 is detachably arranged in the connection groove 83. The support rod 9 is connected to the upper end position of the clamp 82. When the clamp 82 connects all the U-shaped pipes 71 into the ventilation pipe 7, insert the support rod 9 into the connection groove 83. The support rod 9 abuts against the clamp 82 to prevent the ventilation pipe 7 from vibrating during operation and increase the stability of the overall structure. One end of the support rod 9 is provided with a partition plate 91 for connecting with the support frame 5. When the support rod 9 completely extends into the connection groove 83, the partition plate 91 is in close contact with the support frame 5. The partition plate 91 and the support frame 5 are fixed by bolts, which can not only play a limiting role but also ensure the connection quality between the two.

[0033] As Figure 2 , Figure 4 , Figure 5 , Figure 7As shown in the figure, a chute I 53 is provided on the support frame 5, and a chute II 64 is provided on the side plate 6. When the support frame 5 and the side plate 6 are connected, the chute I 53 and the chute II 64 are parallel and aligned. A solar panel 11 is slidably arranged in the chute I 53 and the chute II 64. A plurality of heat preservation plates 12 are provided on the support frame 5. Convex plates 121 are respectively arranged on both sides of the heat preservation plate 12, and the convex plates 121 can be respectively connected in the chute I 53 and the chute II 64. A latch 65 for fixing one side of the heat preservation plate 12 is provided on the support frame 5. The latch 65 passes through the convex plate 121, so that one end of the heat preservation plate 12 is fixed in the chute I 53. A latch 65 for fixing the other side of the heat preservation plate 12 is provided on the side plate 6. The latch 65 passes through the convex plate 121, so that one end of the heat preservation plate 12 is fixed in the chute II 64. The latch 65 fixes the heat preservation plate 12 on the support frame 5. At the same time, the solar panel 11 is connected between the heat preservation plates 12 on both sides. Fixing the heat preservation plate 12 can also fix the solar panel 11 to prevent the solar panel 11 from sliding. The support frame 5, the side plate 6, the solar panel 11 and the heat preservation plate 12 jointly enclose a box structure. The solar panel 11 faces the sunlight direction. When sunlight shines on the solar panel 11, it can provide energy for the solar panel 11. The solar panel 11 stores electricity to provide power for the fan. The solar panel 11 can also store the electric energy in the power storage and supply device, which can be used temporarily and emergently in uninhabited areas, generating economic and social benefits. The heat preservation plate 12 can keep the temperature inside the temperature control component stable and prevent cold air from flowing out.

[0034] The protection structure is supported on the slope 1. A plurality of ventilation pipes 7 are arranged inside the protection structure. In the cold season, cold air can be input into the ventilation pipes 7 through the fan 74 to blow open the movable air door 731 for ventilation convection, so as to keep the slope 1 at a low temperature and prevent the internal frozen soil from melting. At the same time, in the warm season, the movable air door 731 is closed to form an air heat insulation layer to prevent the frozen soil from melting. The whole structure is convenient to disassemble and assemble and is easy to transport. When a certain position is damaged, the damaged position can be repaired, increasing the service life of the overall structure. Compared with the prior art, in the present invention, the ventilation pipes are arranged on the frozen soil slope in a large area, which can cool the frozen soil slope in a large area. At the same time, the fan sends air to the ventilation pipes, making the cooling process stable and efficient.

[0035] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
