Description

Technical Field

[0001] The utility model relates to the technical field of soil and water loss protection, in particular to a mountain soil and water loss protection structure. Background Art

[0002] Mountain slopes are prone to soil erosion. A mountain slope consists of a slope surface, a crest at the top of the slope, and a base at the bottom. During heavy rain, the slope surface is easily eroded by rainwater, especially the crest, where water quickly accumulates. The accumulated water on the crest flows rapidly and in large quantities down the slope surface toward the base. This large amount of rainwater flowing from the crest erodes the slope surface in a short period of time, while the large amount of rainwater flowing down from the crest has a significant impact on the slope surface, causing soil erosion on the slope surface. Slope erosion has the following drawbacks: It causes sediment to accumulate at the base, potentially damaging infrastructure such as roads and bridges at the base, impacting transportation and economic development. If there is a river at the base of the slope, soil erosion can cause sediment to accumulate in the river, potentially blocking it. Therefore, designing structures to protect slopes from soil erosion is crucial. Utility Model Content

[0003] The utility model aims to provide a mountain soil and water loss protection structure to reduce soil and water loss on the slope surface of the mountain.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a mountain soil erosion protection structure, including a slope surface, a slope top located on the slope surface and a slope bottom located on the slope surface, a water retaining member is fixedly provided on the slope top, the top of the water retaining member is higher than the slope top, and the top of the water retaining member extends at least to above the intersection of the slope bottom and the slope surface; a plurality of drainage pipes are connected to the water retaining member, the drainage pipes are laid on the slope surface, and the water outlets of the drainage pipes extend downward to the slope bottom.

[0005] The principle and advantages of this solution are: the function of the water retaining member of this application solution is to block the rainwater on the top of the slope, preventing the rainwater on the top of the slope from flowing quickly and in large quantities toward the slope surface during heavy rain, thereby reducing the scouring of the slope surface, making the slope surface less prone to soil erosion, and helping to keep the mud and soil on the slope surface stable.

[0006] At the same time, the top of the water retaining member extends at least to above the intersection of the bottom of the slope and the slope surface, so that the upper part of the slope surface is blocked by the water retaining member. The water retaining member plays a role in blocking rainwater in the air, which can reduce the soil erosion on the slope surface caused by heavy rain hitting the slope surface, and is conducive to keeping the mud and soil on the slope surface stable.

[0007] The rainwater on the top of the slope is blocked by the water retaining parts and will not flow to the slope surface. The rainwater on the top of the slope gathers at the top of the slope. At the same time, the water retaining parts block the rainwater in the air. The blocked rainwater gathers at the top of the slope along the water retaining parts. At this time, the rainwater on the top of the slope will be discharged to the bottom of the slope along the drainage pipe, thus avoiding the problem of rainwater on the top of the slope continuing to increase and gather and being unable to be discharged downward.

[0008] In summary, the structural design of the present application can reduce the erosion of the slope surface by rainwater during heavy rain, which is beneficial to reducing soil erosion on the slope surface and maintaining the stability of the mud and soil on the slope surface, thereby playing a certain protective role against soil erosion.

[0009] Preferably, as an improvement, the water retaining member is in the shape of an arc-shaped plate.

[0010] Preferably, as an improvement, a plurality of first fixing members are fixed to the top of the slope, each of the first fixing members is threadedly connected with a nut, the bottom of the water retaining member passes through the first fixing members, and the nut fixes the bottom of the water retaining member to the top of the slope.

[0011] Thus, by screwing the nut onto the first fixing member, the bottom of the water retaining member is fixed to the top of the slope, thereby achieving fixation of the water retaining member.

[0012] Preferably, as an improvement, a plurality of pull ropes are connected between the top end of the water retaining member and the top of the slope.

[0013] The water retaining member itself has a certain weight, and when water accumulates in the water retaining member, the weight will increase. If only the bottom of the water retaining member and the bottom of the slope are fixed, the water retaining member will be easily affected by gravity and tilted and bent toward the slope surface, and the bottom of the water retaining member will be easily broken. For this reason, in this solution, a pull rope is set, and the pull rope can pull the water retaining member, which has a pulling force on the water retaining member. The weight of the water retaining member and the weight of the water in the water retaining member can act on the pull rope, reducing the tilt and bending of the water retaining member toward the slope surface. In this way, the water retaining member is fixed on the top of the slope more stably, and the bottom of the water retaining member is not easy to break or damage, which is conducive to improving the service life.

[0014] Preferably, as an improvement, the slope top is fixedly connected with a second fixing member, and the pull rope is fixed on the second fixing member. Thus, by providing the second fixing member, it is convenient to fix the pull rope.

[0015] Preferably, as an improvement, the second fixing member is an anchor rod and the pull rope is a steel rope. The anchor rod is inserted into the slope top to achieve a firm fixation between the second fixing member and the slope top, and the pull rope is a steel rope, which makes the pull rope structure more firm and stable and not easy to be damaged.

[0016] Preferably, as an improvement, the first fixing member is an anchor rod. Thus, the anchor rod is inserted into the slope top, thereby achieving a stable fixation of the first fixing member and the slope top.

[0017] Preferably, as an improvement, a plurality of drip holes are provided on the portion of the water retaining member opposite to the slope surface.

[0018] Because the top of the water retaining member extends at least above the intersection of the slope bottom and the slope surface, while the water retaining member can shield the slope surface from heavy rain, it also blocks the slope surface during light rain. Over time, the plants on the slope surface will be deprived of rainwater and will dry up and die. To address this, the inventors have provided drip holes in the water retaining member. When it rains, a small amount of rainwater can still drip slowly through the drip holes onto the slope surface, thereby irrigating the plants on the slope surface. Since the dripping rainwater is relatively slow and small, it will not scour the slope surface.

[0019] Preferably, as an improvement, the water retaining member is made of plastic material. The water retaining member made of plastic material is lighter in weight and more stable when installed on the top of the slope.

[0020] Preferably, as an improvement, a flexible pressing block is provided on the top of the slope, the pressing block is pressed on the bottom of the water retaining member, the first fixing member vertically passes through the pressing block, and the nut is pressed on the pressing block.

[0021] The nut is pressed on the flexible pressure block, which presses the bottom of the water retaining member against the top of the slope, thereby fixing the water retaining member. The flexible pressure block is provided in this solution to prevent the nut from directly acting on the bottom of the water retaining member and causing damage to the plastic water retaining member. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 This is a cross-sectional view of a mountain soil erosion protection structure.

[0023] Figure 2 for Figure 1 Left view of the middle water retaining member. DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] The figure marks in the drawings of the specification include: mountain 1, slope top 2, slope bottom 3, water retaining member 4, slope surface 5, drainage pipe 6, pressure block 7, nut 8, pull rope 9, second fixing member 10, first fixing member 11, top 12, bottom 13, drip hole 14.

[0026] The embodiment is basically as shown in the attached Figure 1-Figure 2 As shown: a mountain soil erosion protection structure includes a slope surface 5 located on a mountain 1, a slope top 2 located on the slope surface 5 and a slope bottom 3 located on the slope surface 5. The slope surface 5 is inclined, and a water retaining member 4 is fixedly provided on the slope top 2. The water retaining member 4 in this embodiment is an arc-shaped plate. In order to reduce the weight of the water retaining member 4, the water retaining member 4 is preferably made of plastic.

[0027] The bottom 13 of the water retaining member 4 in this embodiment is fixed on the slope top 2. The specific fixing method is as follows: the slope top 2 is fixed with multiple first fixing members 11. The first fixing member 11 in this embodiment is an anchor rod. The top of the first fixing member 11 has a thread. The first fixing member 11 is inserted downward into the slope top 2. Figure 1 As viewed from the left, multiple first fixing members 11 are horizontally arranged in a row (the spacing between adjacent first fixing members 11 is 20-50 cm), and nuts 8 are threadedly connected to the first fixing members 11. The bottom 13 of the water retaining member 4 is provided with multiple through holes, and the first fixing members 11 pass through the through holes. At the same time, a flexible pressure block 7 is provided on the top of the slope 2. The pressure block 7 is preferably made of rubber and is also provided with a through hole. The first fixing member 11 passes through the through hole on the pressure block 7. The pressure block 7 is located above the bottom 13 of the water retaining member 4. By tightening the nut 8, the nut 8 presses the pressure block 7 on the ground of the top of the slope 2, and the pressure block 7 tightly fixes the bottom 13 of the water retaining member 4 to the top of the slope 2.

[0028] The top 12 of the water retaining member 4 in this embodiment is higher than the top 2 of the slope (the vertical distance between the top 12 of the water retaining member 4 and the top 2 of the slope is 30-100 cm in this embodiment), and the top 12 of the water retaining member 4 extends at least to the top of the intersection of the slope bottom 3 and the slope surface 5. The top 12 of the water retaining member 4 in this embodiment extends to the top of the intersection of the slope bottom 3 and the slope surface 5. In this way, the water retaining member 4 can shield the slope surface 5 to a certain extent, reducing the impact of heavy rain in the air on the slope surface 5. Of course, in other embodiments, the water retaining member 4 may not be arc-shaped, and the water retaining member 4 may be configured as a flat plate inclined on the top 2 of the slope.

[0029] In order to improve the stability of the water retaining member 4 on the top of the slope 2 and reduce the situation in which the water retaining member 4 is tilted to the lower right due to its own gravity and the gravity of the rainwater on the water retaining member 4, causing the bottom 13 of the water retaining member 4 to break, a pull rope 9 is connected between the top 12 of the water retaining member 4 and the bottom 3 of the slope in this embodiment. The specific setting method of the pull rope 9 is as follows: the pull rope 9 in this embodiment is a steel rope, and of course it can also be a rope made of other materials. The top of the pull rope 9 is bolted, clamped, hooked or pressed to the top 12 of the water retaining member 4 by a screw (for example, the top 12 of the water retaining member 4 is provided with a hole, and the pull rope 9 passes through the hole in the top 12 of the water retaining member 4 and is bolted, clamped or hooked to the top 12 of the water retaining member 4). The top of the slope 2 is fixedly connected with a plurality of second fixing members 10. Figure 1 In the left view, the second fixing members 10 are arranged in a horizontal row (the spacing between adjacent second fixing members 10 is 20-50 cm). The second fixing members 10 are also anchor rods and are inserted downward into the slope top 2. The pull rope 9 can be fixed to the second fixing members 10 by welding, bolting, etc. The provision of the second fixing members 10 provides a connection point for the pull rope 9 and the slope bottom 3, facilitating the fixing of the bottom end of the pull rope 9 to the slope top 2.

[0030] In this embodiment, the bottom 13 of the water retaining member 4 is connected to a plurality of drain pipes 6. Figure 1 The left side view is arranged horizontally, the drain pipe 6 is laid on the slope surface 5, and the water outlet of the drain pipe 6 extends downward to the bottom of the slope 3. The water retaining member 4 is provided with a plurality of drip holes 14 relative to the slope surface 5, and the hole diameter of the drip hole 14 is set to 1-5mm.

[0031] The specific implementation process is as follows: during heavy rain, the water retaining member 4 blocks the rainwater on the top of the slope 2, preventing the rainwater on the top of the slope 2 from flowing quickly and in large quantities toward the slope surface 5 during heavy rain, thereby reducing the scouring of the slope surface 5. The slope surface 5 is less prone to water and soil erosion, which is conducive to keeping the mud and soil on the slope surface 5 stable.

[0032] At the same time, the water retaining member 4 shields the slope surface 5, which plays a role in shielding rainwater in the air, which is equivalent to the role of an umbrella. It can reduce the soil and water loss on the slope surface 5 caused by heavy rain hitting the slope surface 5, and is conducive to keeping the mud and soil on the slope surface 5 stable.

[0033] Rainwater blocked by the water retaining member 4 and rainwater at the top 2 of the slope is discharged along the drainage pipe 6 to the bottom 3 of the slope, thereby avoiding the problem of rainwater at the top 2 continuously increasing and being unable to be discharged downward. At the same time, rainwater can slowly drip through the drip holes 14, and the dripping rainwater can be used to irrigate plants on the slope surface 5, which is beneficial to plant growth and avoids the plants being blocked by the water retaining member 4 and unable to receive rainwater irrigation for a long time.

[0034] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
