TECHNICAL FIELD
[0001] The utility model relates to the technical field of collapsing gully treatment, more particularly to a simple sand blocking system for collapsing gully treatment. BACKGROUND
[0002] Collapsing gully is one of the main mountain hazards in southern China, which is formed by the collapse and erosion of thick weathering crust of mountain under the joint action of water and gravity. Collapsing gully has extremely high erosion intensity and is called "ecological ulcer" in southern China. Official collapsing gully treatment in China has a history of nearly 80 years. Sand blocking dam is the main measure for collapsing gully treatment at present. However, due to the difficulty of large machinery entering, the construction of sand blocking dam is difficult, and the cost is often as high as hundreds of thousands of yuan. Moreover, due to the large amount of sand from collapsing gully, sand blocking dam is easy to be filled and destroyed, and the subsequent maintenance cost is also high. In addition, the construction period of conventional sand blocking dam is generally more than ten days, which is difficult to effectively respond to sudden collapsing gully disasters. SUMMARY
[0003] The utility model aims at overcoming the deficiency that the prior art is difficult to effectively respond to sudden collapsing gully disasters, and provides a simple sand blocking system for collapsing gully treatment, which is convenient to obtain materials, simple to construct, low in construction and maintenance cost, and fast in effect.
[0004] The utility model adopts the technical scheme of:
[0005] A simple sand blocking system for collapsing gully treatment is provided, which comprises a sand blocking part located in the collapsing gully channel. The sand blocking part has a plurality of sand blocking parts, and the plurality of sand blocking parts are linearly arranged along the axis of the collapsing gully channel. Adjacent two sand blocking parts respectively abut against the two side walls of the collapsing gully channel. In the direction perpendicular to the axis of the collapsing gully channel, the length of the sand blocking part is 0.6-0.8 times the width of the collapsing gully channel. The sand blocking part comprises a blocking body group and a filling body capable of blocking the sediment in the water flow. The blocking body group has two blocking bodies, and the filling body is located between the two blocking body groups. The blocking body group comprises a plurality of blocking bodies linearly arranged in the direction perpendicular to the axis of the collapsing gully channel.
[0006] The sand blocking system of the utility model blocks the water and soil loss in the gully of the collapsing hill by setting several sand blocking parts in the gully of the collapsing hill, and the sand blocking part is simple and convenient to construct, short in construction time, low in cost, and good in effect of avoiding water and soil loss. When the silt in the gully of the collapsing hill is carried by the water flow to flow to the downstream of the collapsing hill, the water flow can pass through the filler in the sand blocking part, and the silt in the water flow is blocked by the filler in the sand blocking part, so that the silt of the collapsing hill is prevented from discharging. The width of the sand blocking part is 0.6-0.8 times of the width of the gully of the collapsing hill, and the two adjacent sand blocking parts are respectively in abutment with the two side walls of the gully of the collapsing hill, so that the drainage channel between the sand blocking parts is in s shape, the length of the drainage channel is further prolonged, the water flow carrying the silt is prevented from flowing to the downstream of the collapsing hill, and the sand blocking effect of the system is improved. In addition to the gully of the collapsing hill, the scheme can also be applied to other types of gully silt blocking situations.
[0007] Preferably, the blocking body is a wooden pile, the length of the blocking body is 1.2-1.5 m, the length of the blocking body extending into the ground is 0.4-0.5 m, and the distance between two adjacent blocking bodies is 0.15-0.25 m. The blocking body is a wooden pile, which is convenient to obtain and low in cost. The length of the blocking body extending into the ground is 0.4-0.5 m, so that the blocking body can be stably fixed in the gully of the collapsing hill, and the impact force of the water flow is prevented from knocking down the sand blocking part. The length of the blocking body extending out of the ground is 0.7-1.1 m, which can better block the silt, and when the silt gradually accumulates to increase the height of the silt, the accumulated silt can also be blocked. The gap between two adjacent blocking bodies is filled with a filler, and the thickness of the filler is 0.15-0.25 m, which can better block the silt in the water flow.
[0008] Preferably, the distance between two blocking body groups is 0.4-0.6 m, the filler is plant stems and / or branches, and the filler filling the gap between two blocking body groups is water-permeable but sand-impermeable. The distance between two blocking body groups is 0.4-0.6 m, i.e. the filling thickness of the filler is 0.4-0.6 m, which ensures that the filler has good sand blocking effect. The filler is plant stems and / or branches, which are easy to obtain in the wild environment, so that the material carrying time is reduced when the sand blocking system is constructed, and the cost of the plant stems and branches is low, which can further reduce the cost of constructing the sand blocking system. After the filler is filled into the gap between two blocking body groups, the filler is slightly compacted, so that the gap between the fillers is water-permeable but sand-impermeable, the silt is prevented from flowing through the sand blocking part along the gap, and the sand blocking effect of the sand blocking part is enhanced.
[0009] Preferably, the sand blocking part further comprises fixing piles, the fixing piles are located between two groups of the blocking bodies and the distance between the fixing piles and the two groups of the blocking bodies is equal, the fixing piles are several, and the several fixing piles are linearly arranged in a direction perpendicular to the axis of the gully. The fixing piles are wooden piles, the length of the fixing piles is 1.2-1.5 m, the length of the fixing piles extending into the ground is 0.4-0.5 m, and the distance between two adjacent fixing piles is 1-1.2 m. After the fixing piles are arranged, the fixing piles can increase the installation strength of the filling body and improve the resistance of the sand blocking part to the water flow impact. The fixing piles are wooden piles, and the wooden piles are convenient to obtain and have low cost as the material of the blocking bodies.
[0010] Preferably, the number of the sand blocking parts located upstream of the gully is not less than two, and the number of the sand blocking parts located downstream of the gully is not less than four. In the upstream area of the gully, at least two sand blocking parts are arranged, and at least four sand blocking parts are arranged in the downstream area, so that the sand blocking efficiency of the downstream area is higher, and the sediment is not easy to flow out of the gully. The number of the sand blocking parts in the downstream area of the gully is more than that in the upstream area, because the downstream gully of the gully is wide, and the water flow is usually not uniformly distributed in the transverse direction, but may be concentrated on the left side, the right side or the middle position. By arranging at least four sand blocking parts in the downstream area, no matter where the water flow is concentrated, the sediment is subjected to a strong interception effect.
[0011] Preferably, the distance between two adjacent sand blocking parts in the sand blocking parts located upstream of the gully is 0.4-0.7 m, and the distance between two adjacent sand blocking parts in the sand blocking parts located downstream of the gully is also 0.4-0.7 m. The greater the distance between two adjacent sand blocking parts, the wider the width of the drainage channel, the more sediment the water flow carries when flowing through, and the worse the sand blocking effect of the sand blocking part. The narrower the width of the drainage channel, the slower the flow speed of the water flow in the drainage channel, and the greater the impact force of the water flow on the sand blocking part. According to experiments, when the distance between the sand blocking parts is 0.4-0.7 m, the water flow can not carry a large amount of sediment, and the sand blocking part can not be washed away by the water flow.
[0012] Preferably, two adjacent blocking bodies are connected through a connecting part. The connecting part can be made of materials such as wood boards, bamboo boards and branches, which are convenient to obtain. The blocking bodies can be nailed on the wood boards or bamboo boards, or the branches are wound on the blocking bodies in sequence to form a fence blocking body. The blocking bodies nailed on the wood boards or bamboo boards are connected through the wood boards or bamboo boards, which can further avoid that a certain blocking body is washed away by the water flow and improve the impact resistance of the blocking body. The branches wound on the blocking bodies in sequence form a fence blocking body, which can further enhance the sand blocking effect on the premise of improving the impact resistance of the blocking body.
[0013] Preferably, the axis of the sand blocking part is perpendicular to the axis of the gully channel.
[0014] Preferably, the sand blocking part is arranged in the gully channel in an inclined manner, and an end of the sand blocking part away from the side wall of the gully channel is inclined to the downstream of the gully channel.
[0015] Compared with the prior art, the sand blocking system has the following advantages:
[0016] The sand blocking system of the utility model prevents water and soil loss in the gully channel by arranging a plurality of sand blocking parts in the gully channel.
[0017] In the sand blocking system, the blocking body and the fixing pile are wooden piles, and the filling body is plant stems and / or branches, which are convenient to obtain and low in cost.
[0018] The sand blocking system of the utility model can increase the length of the sand blocking part when the width of the gully of the collapsed hill is narrow, thereby increasing the number of the blocking bodies in the sand blocking part, and achieving the purpose of improving the risk resistance of the sand blocking part.

The sand blocking part 1 comprises a stop body group and a filling body 3 capable of blocking the sediment in the water flow. The stop body group has two stop bodies 2, and the filling body 3 is located between the two stop body groups. The stop body group comprises a plurality of stop bodies 2 arranged linearly in the direction perpendicular to the axis of the gully channel 5. Figure 1
[0028] The beneficial effects of the embodiment are as follows:
[0029] The sand blocking system of the embodiment blocks the water and soil loss in the gully channel 5 by arranging a plurality of sand blocking parts 1 in the gully channel 5. The sand blocking part 1 is simple and convenient to construct, has a short construction time, low cost, and good effect of avoiding water and soil loss. When the sediment in the gully channel 5 is carried by the water flow to flow downstream of the gully, the water flow can pass through the filling body 3 in the sand blocking part 1, and the sediment in the water flow will be blocked by the filling body 3 in the sand blocking part 1 to avoid sediment discharge. The width of the sand blocking part 1 is 0.6-0.8 times the width of the gully channel 5, and the adjacent two sand blocking parts 1 respectively abut the two side walls of the gully channel 5. The drainage channel 6 composed of a plurality of sand blocking parts 1 is in the shape of s, which can further prolong the length of the drainage channel 6, prevent the water flow from carrying sediment to flow downstream of the gully, and improve the sand blocking effect of the system.
[0030] Embodiment two
[0031] The embodiment is a second embodiment of a simple sand blocking system for gully management, as shown in the figure, which is further limited to the structure of the sand blocking system on the basis of the first embodiment. Figure 2
[0032] Specifically, the stop body 2 is a wooden pile, the length of the stop body 2 is 1.2-1.5 m, the length of the stop body 2 extending into the ground is 0.4-0.5 m, and the distance between the adjacent two stop bodies 2 is 0.15-0.25 m. The distance between the two stop body groups is 0.4-0.6 m, the filling body 3 is a plant stem and / or branch, and the filling body 3 fills the gap between the two stop body groups and is compacted.
[0033] Specifically, the sand blocking part 1 further comprises a fixing pile 4, the fixing pile 4 is located between the two stop body groups, and the distance between the fixing pile 4 and the two stop body groups is equal. The fixing pile 4 has a plurality of fixing piles 4 arranged linearly in the direction perpendicular to the axis of the gully channel 5.
[0034] Specifically, as shown in the figure, Figure 2 As shown, at least two sand blocking parts 1 are arranged upstream of the gully 5. Figure 3 As shown, at least four sand blocking parts 1 are arranged downstream of the gully 5. In the sand blocking parts 1 arranged upstream of the gully 5, the distance between two adjacent sand blocking parts 1 is 0.4m-0.7m; in the sand blocking parts 1 arranged downstream of the gully 5, the distance between two adjacent sand blocking parts 1 is also 0.4m-0.7m.
[0035] Specifically, the two adjacent blocking bodies 2 are connected by twining branches to form a fence. When the gully 5 is wide, the axis of the sand blocking part 1 is perpendicular to the axis of the gully 5.
[0036] The beneficial effects of the embodiment are as follows:
[0037] The blocking body 2 is a wooden pile, which is easy to obtain and low in cost. The length of the blocking body 2 under the ground is 0.4m-0.5m, so that the blocking body 2 can be stably fixed in the gully 5 to avoid the impact of water flow. The length of the blocking body 2 above the ground is 0.7m-1.1m, which can better block the sediment. When the sediment gradually accumulates and the height of the sediment increases, the accumulated sediment can also be intercepted. The gap between the two adjacent blocking bodies 2 is filled with the filling body 3, and the thickness of the filling body 3 is 0.15m-0.25m, which can better block the sediment in the water flow.
[0038] The distance between the two blocking body groups is 0.4m-0.6m, that is, the filling thickness of the filling body 3 is 0.4m-0.6m, which ensures that the filling body 3 has good sand blocking effect. The filling body 3 is a plant stem and / or branch, which is easy to obtain in the wild environment, can reduce the material transportation time when constructing the sand blocking system, and is low in cost, which can further reduce the cost of constructing the sand blocking system. After the filling body 3 is filled into the gap between the two blocking body groups, the filling body 3 is compacted, which can further reduce the gap between the plant stems and branches, avoid the sediment flowing through the sand blocking part 1 along the gap, and enhance the sand blocking effect of the sand blocking part 1.
[0039] After the fixed pile 4 is arranged, the fixed pile 4 can further increase the installation strength of the sand blocking part 1 in the gully 5 and improve the resistance of the sand blocking part 1 to water flow impact. The fixed pile 4 is a wooden pile, which is easy to obtain and low in cost.
[0040] At least two sand blocking parts 1 are arranged upstream of the gully 5, and at least four sand blocking parts 1 are arranged downstream of the gully 5, which can make the sand blocking efficiency higher downstream of the gully 5, and the sediment is not easy to flow out of the gully. When the distance between the sand blocking parts 1 is 0.4m-0.7m, the water flow can not carry away a large amount of sediment, and the sand blocking part 1 will not be washed away by the water flow.
[0041] The branches of the retaining body 5 intertwine to form a fence-like barrier, which not only improves the impact resistance of the retaining body 5 but also further enhances the sand-blocking effect. When the width of the gully erosion channel 5 is relatively wide, the axis of the sand-blocking part 1 is perpendicular to the axis of the gully erosion channel 5. At this time, the length of the sand-blocking part 1 is relatively large, and the sand-blocking part 1 includes a large number of retaining bodies 2. Even if one or more retaining bodies 2 are damaged, the sand-blocking part 1 can be prevented from being washed away by the water flow, thus improving the risk resistance of the sand-blocking part 1.
[0042] Example 3
[0043] This embodiment is a third embodiment of a simple sand-trapping system for gully erosion control, such as... Figure 4 As shown, this embodiment is similar to Embodiment 2, except that when the width of the gully 5 is narrow, the sand-blocking part 1 is inclined within the gully 5, and one end of the sand-blocking part 1 away from the side wall of the gully 5 is inclined downstream of the gully 5. The acute angle between the axis of the sand-blocking part 1 and the side wall of the gully 5 is 30°-75°.
[0044] The beneficial effects of this embodiment are as follows:
[0045] When the width of the gully 5 is narrow, the sand-blocking section 1 is installed at an angle within the gully 5. This increases the length of the sand-blocking section 1, thereby increasing the number of retainers 2 within it and improving its ability to withstand risks. The sand-blocking section 1 is tilted downstream of the gully 5, ensuring its sand-blocking capacity while further extending its service life.
[0046] Other features and beneficial effects of this embodiment are the same as those of Embodiment 2.
[0047] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
