Description

Technical Field

[0001] The present application relates to the technical field of slope drainage, and in particular to a high-steep slope rapid flow trough and a construction method thereof. Background Art

[0002] A high steep slope rapid flow trough is a facility used in drainage projects in mountainous areas or steep terrain. It is mainly used to guide and control the runoff on the mountain surface to prevent the water flow from directly eroding the slope, thereby reducing soil erosion and protecting the stability of the slope. This facility is usually used on highway, railway slopes and other artificial or naturally formed steep slopes.

[0003] Traditional drainage methods such as natural drainage and simple drainage ditches often have insufficient drainage capacity when facing rapids and heavy rainfall, and are also very likely to cause slope scour, thereby exacerbating soil erosion. Therefore, it is particularly important to develop a construction method that can effectively cope with rapid drainage of high and steep slopes while maintaining slope stability. Summary of the invention

[0004] The purpose of the present application is to provide a high-steep slope rapid flow trough and a construction method thereof.

[0005] In the first aspect, the present application provides a high steep slope rapids trough adopting the following technical solution: A rapids trough on a high and steep slope comprises a rock and soil layer, a drainage pipe and a vegetation planting area. A rapids trough body is installed on the top of the rock and soil layer, a guide pipe is connected to the bottom of the rapids trough body, the drainage pipe is connected to one end of the guide pipe away from the rapids trough body, and the vegetation planting area covers both sides of the rapids trough body.

[0006] By adopting the above technical scheme, a rapids trough body is excavated on the rock and soil layer, and a reserved drainage outlet is excavated at the bottom of the rapids trough body for connection with the diversion pipe. The diversion pipe is an L-shaped structure, and the other end is connected to the drainage pipe. When there is too much water flow inside the rapids trough body, part of the water flow will flow into the drainage pipe through the diversion pipe, and then flow into the river or drainage system through the drainage pipe, thereby increasing the drainage speed of the entire rapids trough body.

[0007] Optionally, the guide pipes are evenly and equidistantly installed at the bottom of the rapid flow trough body, the guide pipes are sealed and connected to one side of the drain pipe, the end of the drain pipe is connected to the drainage system or a natural water body, a collecting trough is provided at the top of the rapid flow trough body, a collecting frame is provided inside the collecting trough, a handle is installed on the top of the collecting frame, an installation groove is provided on the inner wall of the rapid flow trough body, a blocking net is inserted inside the installation groove, and a filter net is installed on the top of the guide pipe.

[0008] By adopting the above technical solution, since the diversion pipes are connected to the bottom of the rapid flow trough body through the drainage outlets at uniform and equidistant intervals, the flow speed of water at different points of the rapid flow trough body can be increased through the diversion pipes. At the same time, the diversion pipes and the drainage pipes are sealed to avoid water seepage at the connection between the diversion pipes and the drainage pipes, which may cause the surrounding soil to loosen and lose. At the same time, a collection frame is provided in the collection trough at the top of the rapid flow trough body. When debris in the water flow moves with the water flow, larger and heavier debris will flow through the rapid flow trough body to the collection frame, thereby facilitating the collection of larger and heavier debris in the water flow, while some smaller debris floating with the water flow will pass through the rapid flow trough body. The fence in the mounting groove on the inner wall of the body is used to intercept debris in the water flow, thereby facilitating the rapid removal of debris in the water flow and avoiding the blockage of the rapid flow trough body due to excessive debris. When it is necessary to collect and clean the debris in the collection frame, you only need to pull the collection frame out of the collection trough through the handle, and then you can clean the debris in the collection frame. At the same time, the blocking net can be slid out from the inner wall of the rapid flow trough body through the mounting groove, thereby facilitating the collection and cleaning of the debris in the blocking net. Moreover, since the filter screen is installed between the drain outlet and the guide pipe at the bottom of the rapid flow trough body, impurities in the water can be filtered through the filter screen, thereby avoiding the impurities flowing into the guide pipe and causing blockage in the guide pipe.

[0009] Optionally, a fixing frame is installed on the top of the rapids trough body, and a guide frame is installed on the top of the fixing frame through a supporting frame, a first motor is installed on one side of the guide frame, the output end of the first motor is connected to a screw via a coupling, the outer side of the screw is sleeved with a first screw sleeve, the middle of the first screw sleeve is penetrated and connected, the top of the screw is connected to a second motor through a coupling, the outer side of the screw is sleeved with a second screw sleeve, one side of the second screw sleeve is connected to a connecting block, the bottom of the connecting block is connected to a movable net, a connecting frame is installed on the top of the blocking net, a fixed block is installed on the top of the connecting frame, a third motor is installed on one side of the fixed block, the output end of the third motor is connected to a threaded rod via a coupling, the outer side of the threaded rod is sleeved with a third screw sleeve, and one side of the third screw sleeve is connected to a plug rod penetrating the fixed block.

[0010] By adopting the above technical solution, when it is necessary to collect the debris in the blocking net, it is only necessary to start the second motor at the top of the first screw sleeve. Since the second motor is connected to the screw through a coupling, the second motor will drive the screw to rotate. The top of the screw is connected to the first screw sleeve through a bearing, and the bottom is slidably connected to the fixed frame through a bearing seat. A second screw sleeve is also sleeved on the outside of the screw, and a guide rod is connected through the middle of the second screw sleeve. Therefore, when the screw rotates, it will drive the second screw sleeve to slide up and down through the guide rod. A movable net is connected to one side of the second screw sleeve through a connecting block. When the second screw sleeve slides downward, it will drive the movable net to move downward through the connecting block, so that the movable net moves downward along the fixed frame. At the same time, since the fixed block on the connecting frame at the top of the blocking net is plugged into one side of the connecting block through the plug rod, the connecting block moves upward, which can drive the blocking net to move. The net moves upward, and when the blocking net is pulled to the top of the rapid flow trough body, the first motor can be started, so that the first motor drives the screw rod to rotate. Since the first screw sleeve is connected to the outside of the screw rod, and the first screw sleeve is slidably connected to the guide frame, the screw rod will drive the first screw sleeve to slide along the guide frame when it rotates. At the same time, the first screw sleeve will drive the screw rod to move, and drive the movable net and the blocking net to move through the connecting block. When the movable net and the blocking net move to one side of the top of the rapid flow trough body, the third motor is started, so that the third motor drives the threaded rod to rotate in the opposite direction again, and drives the plug rod to move out of the groove of the connecting block through the third screw sleeve. At this time, the plug rod will be separated from the connecting block, and there is no restriction on the blocking net by the plug rod and the connecting block. The net will slide down to the rapid flow trough body again, so as to facilitate the automatic collection and cleaning of impurities in the net, thereby avoiding the entire rapid flow trough body from being blocked by the accumulation of debris, and making it easier for the entire rapid flow trough body to drain.

[0011] In the second aspect, the present application provides a method for constructing a rapid flow trough on a high steep slope, which adopts the following technical solution: A method for constructing a rapid flow trough on a high steep slope, comprising the following steps: S1: Accurately measure and plan the location, size and shape of the rapids trough according to the topography, geological conditions and drainage requirements of the slope; S2: Excavate the foundation trench of the rapids trough body and the reserved collection trough along the planned route, and carry out necessary reinforcement treatment on the foundation trench; S3: Use high-strength, corrosion-resistant and erosion-resistant materials to construct the rapids trough body to increase its structural stability; S4: a drainage outlet is provided at the end of the rapid flow trough body or at an appropriate position and connected to the drainage pipe by a guide pipe; S5: According to the size of the rapid flow trough body and the guide pipe, a screen and a filter of corresponding size are manufactured and installed and fixed; S6: Carry out vegetation restoration in the vegetation planting area around the rapids trough body and plant suitable vegetation.

[0012] Optionally, when planning the location of the rapids trough body in S1, coordination with the slope topography should be ensured, while ensuring smooth drainage.

[0013] Optionally, when the foundation trench of the rapid flow trough body is excavated in S2, the rapid flow trough body can be reinforced by installing anchor rods, steel bars, and pouring concrete to enhance the stability of the rapid flow trough.

[0014] Optionally, S3 may use one or more of natural stone, prestressed concrete, polyethylene plastic, and polypropylene plastic and evenly lay them in the rapids trough body, thereby increasing the strength, corrosion resistance, and scour resistance of the entire rapids trough body.

[0015] By adopting the above technical scheme, the position, route and size of the rapid flow trough body are first planned according to the slope terrain to ensure that the entire rapid flow trough body can drain smoothly. Then, when excavating the foundation trough of the rapid flow trough body, corresponding anchor rods, steel bars or poured concrete can be set in the foundation trough of the rapid flow trough body according to construction requirements, so that the foundation trough of the rapid flow trough body can be pre-treated, thereby increasing the stability of the foundation trough of the entire rapid flow trough body. Then, one or more of natural stone, prestressed concrete, polyethylene plastic and polypropylene plastic are laid on the surface of the rapid flow trough body. The above materials can increase the strength, corrosion resistance and scour resistance of the entire rapid flow trough body, thereby preventing the rapid flow trough body from being damaged by long-term erosion by rainwater.

[0016] Optionally, when the guide pipe and the drainage pipe are connected and fixed in S4, a triangular joint or sealant can be used for adhesive connection to ensure that there is no water seepage at the connection between the guide pipe and the drainage pipe, and the guide pipe and the drainage pipe are pre-buried in the rock and soil layer.

[0017] Optionally, the blocking net in S5 is installed in the rapid flow trough body through the installation groove reserved in the inner wall of the rapid flow trough body, and the filter net is installed on the top of the guide pipe through the groove between the rapid flow trough body and the drain outlet.

[0018] Optionally, in S6, soil may be covered in the vegetation planting area on both sides of the rapids trough body, and then corresponding vegetation may be planted, thereby reducing direct scouring of the slope by water flow and enhancing the stability of the slope.

[0019] By adopting the above technical scheme, the bottom of the rapid trough body is connected to the diversion pipe through the drainage port, and multiple groups of diversion pipes are connected to the drainage pipe. The drainage speed of the entire rapid trough body can be increased through the diversion pipe and the drainage pipe. At the same time, the impurities in the water flow can be filtered and intercepted through the blocking net and the filter, thereby avoiding the blockage of the rapid trough body. Finally, suitable vegetation is planted in the vegetation planting area on both sides of the rapid trough body. The root system of the plant can penetrate deep into the soil to form a complex network structure, thereby increasing the stability of the soil and effectively preventing soil erosion. The leaves and stems of the plants can intercept rainfall and reduce the force of rainwater directly impacting the ground, thereby reducing the erosion of rainwater on the soil surface and increasing the stability of the entire rapid trough body and the slope.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: 1. The drainage port at the bottom of the rapid trough body is connected to a diversion pipe, and the other end of the diversion pipe is connected to a drainage pipe. When the water flow inside the rapid trough body is too large, part of the water flow can flow into the drainage pipe through the diversion pipe, and then flow into the river through the drainage pipe. At the same time, a collection frame is installed inside the rapid trough body through the collection trough. Larger debris in the water flow will be washed into the collection frame, while smaller debris will be intercepted by the blocking net. While increasing the drainage speed of the rapid trough body, it can also prevent debris from causing blockage of the rapid trough body. 2. When it is necessary to collect and clean the debris in the blocking net, it is only necessary to drive the screw to rotate through the second motor, and the screw will drive the connection and movable net to move downward through the second screw sleeve, and then cooperate with the third motor to drive the plug rod and the connecting block to connect, and then cooperate with the screw and the second screw sleeve to drive the movable net and the blocking net to move upward. When the blocking net and the movable net move to the top of the rapid flow trough body, the first motor drives the screw rod and the first screw sleeve to slide, so as to move the movable net and the blocking net to one side of the top of the rapid flow trough body, and then the third motor drives the plug rod to separate from the connecting block. Under the action of gravity, the blocking net will move downward, so that the debris in the blocking net can be shaken off, which is convenient for collecting and cleaning the impurities in the blocking net, thereby avoiding the phenomenon of impurity blockage in the rapid flow trough body.

[0021] 3. The entire rapid trough body is first installed along the specified line to excavate the foundation trench, and then the foundation trench is reinforced by anchor rods or concrete. After the foundation trench of the rapid trough body is reinforced, one or more materials including natural stone, prestressed concrete, polyethylene plastic, and polypropylene plastic are evenly laid on the surface, thereby improving the strength, corrosion resistance and scour resistance of the rapid trough body. Finally, corresponding plants are planted in the vegetation planting areas on both sides of the rapid trough body, thereby increasing the soil strength around the rapid trough body and avoiding damage to the rapid trough body.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0025] Embodiment 1: A rapids trough on a high and steep slope comprises a rock and soil layer 1, a drainage pipe 4 and a vegetation planting area 5. A rapids trough body 2 is installed on the top of the rock and soil layer 1, a guide pipe 3 is connected to the bottom of the rapids trough body 2, the drainage pipe 4 is connected to the end of the guide pipe 3 away from the rapids trough body 2, and the vegetation planting area 5 covers both sides of the rapids trough body 2. The rapids trough body 2 is excavated on the rock and soil layer 1, and a reserved drainage port is excavated at the bottom of the rapids trough body 2 for connection with the guide pipe 3. The guide pipe 3 is an L-shaped structure, and the other end is connected to the drainage pipe 4. When there is too much water flow inside the rapids trough body 2, part of the water will flow through the guide pipe 3 to the drainage pipe 4, and then flow through the drainage pipe 4 to the river or drainage system, thereby increasing the drainage speed of the entire rapids trough body 2.

[0026] The guide pipes 3 are evenly installed at the bottom of the rapid flow trough body 2 at equal distances. The guide pipes 3 are sealed and connected to one side of the drain pipe 4. The end of the drain pipe 4 is connected to the drainage system or natural water body. A collecting trough 6 is provided at the top of the rapid flow trough body 2. A collecting frame 7 is arranged inside the collecting trough 6. A handle 8 is installed on the top of the collecting frame 7. An installation groove 9 is provided on the inner wall of the rapid flow trough body 2. A blocking net 10 is inserted inside the installation groove 9. A filter screen 11 is installed on the top of the guide pipe 3. Since the guide pipes 3 are evenly connected to the bottom of the rapid flow trough body 2 through the drain port at equal distances, the flow velocity of the water flow at different points of the rapid flow trough body 2 can be increased through the guide pipe 3. At the same time, the guide pipe 3 and the drain pipe 4 are sealed and connected, so as to avoid water seepage at the connection between the guide pipe 3 and the drain pipe 4, which may cause the surrounding soil to loosen and lose. At the same time, a collecting frame 7 is arranged in the collecting trough 6 at the top of the rapid flow trough body 2. When the debris in the water flow moves with the water flow, it is relatively Large and heavier debris will flow into the collecting frame 7 through the rapid flow trough body 2, thereby facilitating the collection of larger and heavier debris in the water flow, while some smaller debris floating with the water flow will be intercepted by the blocking net 10 in the mounting groove 9 on the inner wall of the rapid flow trough body 2, thereby facilitating the rapid removal of debris in the water flow and avoiding the blockage of the rapid flow trough body 2 due to excessive debris. When it is necessary to collect and clean the debris in the collecting frame 7, it is only necessary to pull the collecting frame 7 out of the collecting trough 6 through the handle 8, and then the debris in the collecting frame 7 can be cleaned. At the same time, the blocking net 10 can be slid and pulled out from the inner wall of the rapid flow trough body 2 through the mounting groove 9, thereby facilitating the collection and cleaning of the debris in the blocking net 10. Moreover, since the filter screen 11 is installed between the drain outlet and the guide pipe 3 at the bottom of the rapid flow trough body 2, the impurities in the water can be filtered through the filter screen 11, thereby avoiding the impurities flowing into the guide pipe 3 and causing the guide pipe 3 to be blocked.

[0027] A fixing frame 12 is installed on the top of the rapids trough body 2, a guide frame 13 is installed on the top of the fixing frame 12 through a support frame, a first motor 14 is installed on one side of the guide frame 13, an output end of the first motor 14 is connected to a screw rod 15 through a coupling, a first screw sleeve 16 is sleeved on the outer side of the screw rod 15, a screw rod 17 is connected through the middle of the first screw sleeve 16, a second motor 18 is connected to the top of the screw rod 17 through a coupling, a second screw sleeve 19 is sleeved on the outer side of the screw rod 17, a connecting block 20 is connected to one side of the second screw sleeve 19, a movable net 21 is connected to the bottom of the connecting block 20, a connecting frame 22 is installed on the top of the blocking net 10, a fixing block 23 is installed on the top of the connecting frame 22, a third motor 24 is installed on one side of the fixing block 23, and the third motor 2 The output end of the first screw sleeve 16 is connected to the output end of the first screw sleeve 16 through a coupling, and the outer side of the threaded rod 25 is sleeved with a third screw sleeve 26. One side of the third screw sleeve 26 is connected with a plug rod 27 that penetrates the fixed block 23. When it is necessary to collect the debris in the barrier net 10, it is only necessary to start the second motor 18 at the top of the first screw sleeve 16. Since the second motor 18 is connected to the screw rod 17 through a coupling, the second motor 18 will drive the screw rod 17 to rotate. The top of the screw rod 17 is connected to the first screw sleeve 16 through a bearing, and the bottom is slidably connected to the fixed frame 12 through a bearing seat. A second screw sleeve 19 is also sleeved on the outer side of the screw rod 17, and a guide rod is penetrated and connected in the middle of the second screw sleeve 19. Therefore, when the screw rod 17 rotates, it will drive the second screw sleeve 19 to rotate through the guide rod. The movable net 21 is connected to one side of the second screw sleeve 19 through the connecting block 20. When the second screw sleeve 19 slides downward, the movable net 21 is driven to move downward through the connecting block 20, so that the movable net 21 moves downward along the fixed frame 12 and moves to one side of the blocking net 10. The debris in the blocking net 10 can be intercepted by the movable net 21, and then the third motor 24 is started, and the third motor 24 drives the threaded rod 25 to rotate. The top of the threaded rod 25 is connected to the plug rod 27 through the third screw sleeve 26, and the plug rod 27 can only slide along the groove of the fixed block 23. Therefore, the threaded rod 25 will drive the plug rod 27 to move when it rotates, so that the plug rod 27 is plugged into the groove on one side of the connecting block 20, and then the third motor 24 is started again. When the second motor 18 is started, the second motor 18 will drive the screw 17 to rotate in the opposite direction. The reverse rotation of the screw 17 will drive the movable net 21 to move upward through the second screw sleeve 19 and the connecting block 20. At the same time, since the fixed block 23 on the connecting frame 22 at the top of the blocking net 10 is plugged into one side of the connecting block 20 through the plug rod 27, the upward movement of the connecting block 20 can drive the blocking net 10 to move upward. When the blocking net 10 is pulled to the top of the rapids tank body 2, the first motor 14 can be started, so that the first motor 14 drives the screw rod 15 to rotate. Since the first screw sleeve 16 is connected to the outer side of the screw rod 15, and the first screw sleeve 16 is slidably connected to the guide frame 13, the screw rod 15 will drive the first screw sleeve 16 to slide along the guide frame 13 when it rotates.At the same time, the first screw sleeve 16 will drive the screw rod 17 to move, and drive the movable net 21 and the blocking net 10 to move through the connecting block 20. When the movable net 21 and the blocking net 10 move to one side of the top of the rapids tank body 2, the third motor 24 is started again, so that the third motor 24 drives the threaded rod 25 to rotate in the opposite direction again, and drives the plug rod 27 to move out of the groove of the connecting block 20 through the third screw sleeve 26. At this time, the plug rod 27 will be separated from the connecting block 20. Without the limiting effect of the plug rod 27 and the connecting block 20 on the blocking net 10, the blocking net 10 will slide downward along the support frame between the fixed frame 12 and the guide frame 13 under the effect of gravity. The impurities in the blocking net 10 will be shaken off, so it is convenient to clean the impurities in the blocking net 10. Finally, repeat the above steps, pull the blocking net 10 upward through the connecting block 20, and then pull the blocking net 10 to the top of the rapid trough body 2. When the blocking net 10 moves to the top of the rapid trough body 2, the plug 27 is separated from the connecting block 20 again. At this time, the blocking net 10 will slide down to the rapid trough body 2 again, so it is convenient to automatically collect and clean the impurities in the blocking net 10, thereby avoiding the entire rapid trough body 2 from being blocked by the accumulation of debris, so that the entire rapid trough body 2 is more convenient to drain.

[0028] The implementation principle of the embodiment of the present application is as follows: first, the bottom of the rapid flow trough body 2 is connected to the guide pipe 3 through the drain outlet, and the other side of the guide pipe 3 is connected to the drain pipe. When the water flow inside the rapid flow trough body 2 is too large, part of the water flow can flow into the drainage system through the guide pipe 3 and the drain pipe. The drainage speed of the entire rapid flow trough body 2 can be increased through the rapid flow trough body 2 and the drain pipe. At the same time, a collecting frame 7 is installed in the collecting trough 6 inside the rapid flow trough body 2. Some heavier and larger debris will be washed into the collecting frame, while some smaller debris can flow to one side of the blocking net with the water flow. The blocking net and the collecting frame 7 can collect and intercept the debris in the water flow, and the filter screen on the top of the guide pipe can be used to avoid blockage of the rapid flow trough body 2 and the guide pipe. Finally, the debris on the collecting frame 7, the blocking net 10 and the filter screen 11 can be cleaned regularly, so as not to affect the drainage effect of the entire rapid flow trough body 2.

In S3, one or more of natural stone, prestressed concrete, polyethylene plastic and polypropylene plastic can be used to evenly lay them in the rapid trough body 2, thereby increasing the strength, corrosion resistance and scour resistance of the entire rapid trough body 2. First, the position, line and size of the rapid trough body 2 are planned according to the slope terrain to ensure that the entire rapid trough body 2 can drain smoothly. Then, when excavating the foundation trough of the rapid trough body 2, corresponding anchor rods, steel bars or poured concrete can be set in the foundation trough of the rapid trough body 2 according to construction requirements, so that the foundation trough of the rapid trough body 2 can be pre-treated, thereby increasing the stability of the foundation trough of the entire rapid trough body 2. Then, one or more of natural stone, prestressed concrete, polyethylene plastic and polypropylene plastic are laid on the surface of the rapid trough body 2. The above materials can increase the strength, corrosion resistance and scour resistance of the entire rapid trough body 2, and avoid the rapid trough body 2 being damaged by rainwater erosion for a long time; S4: a drainage port is arranged at the end or at an appropriate position of the rapid flow trough body 2 and connected to the drainage pipe 4 by a diversion pipe 3. When the diversion pipe 3 and the drainage pipe 4 are connected and fixed in S4, a triangular joint or a sealant can be used for bonding to ensure that no water seepage occurs at the connection between the diversion pipe 3 and the drainage pipe 4. At the same time, the diversion pipe 3 and the drainage pipe 4 are pre-buried in the rock and soil layer 1; S5: According to the sizes of the rapid flow trough body 2 and the guide pipe 3, a blocking net 10 and a filter screen 11 of corresponding sizes are manufactured and installed and fixed.

In S6, soil can be covered in the vegetation planting area 5 on both sides of the rapid trough body 2, and then corresponding vegetation can be planted, so as to reduce the direct scouring of the slope by the water flow and enhance the stability of the slope. At the same time, the bottom of the rapid trough body 2 is connected to the diversion pipe 3 through the drainage port, and multiple groups of diversion pipes 3 are connected to the drainage pipe 4. The drainage speed of the entire rapid trough body 2 can be increased through the diversion pipe 3 and the drainage pipe 4. At the same time, the intercepting net 10 The filter 11 can filter and intercept impurities in the water flow, thereby avoiding blockage of the rapid trough body 2. Finally, suitable vegetation is planted in the vegetation planting area 5 on both sides of the rapid trough body 2. The root system of the plant can penetrate deep into the soil to form a complex network structure, thereby increasing the stability of the soil and effectively preventing soil erosion. The leaves and stems of the plants can intercept rainfall and reduce the force of rainwater directly impacting the ground, thereby reducing the erosion of rainwater on the soil surface and increasing the stability of the entire rapid trough body 2 and the slope.

After the excavation of the foundation trench is completed, in order to increase the overall stability, anchor rods or steel bars are laid inside the foundation trench of the rapid trough body 2, and concrete is poured, thereby increasing the stability of the foundation trench of the entire rapid trough body 2. Then, one or more materials selected from natural stone, prestressed concrete, polyethylene plastic, and polypropylene plastic are laid inside the foundation trench of the rapid trough body 2, thereby increasing the strength, corrosion resistance and scour resistance of the entire rapid trough body 2. After installing the corresponding filter screen and barrier screen, the soil can be covered in the vegetation planting area 5 on both sides of the rapid trough body 2 and the corresponding plants can be planted. The soil strength can be increased by plants, thereby avoiding the loss of soil around the rapid trough body 2 and causing damage to the rapid trough body 2.
