Description

Technical Field

[0001] This invention relates to the field of slope drainage technology, and in particular to a drainage system for fragile slopes and its installation method. Background Technology

[0002] Vulnerable slopes refer to slopes that are prone to instability and damage under natural or human factors. These slopes are usually composed of softer soil and rock layers, or have defects in geological structure, topography, hydrogeology, etc., resulting in poor stability. Vulnerable slopes can cause serious harm and threaten people's lives and property as well as the natural environment. In particular, when there is a lot of rainfall, rainwater can easily cause significant damage and impact on the slope, accelerate the infiltration of water in the soil, reduce the stability of the foundation, and thus cause landslides, collapses and other phenomena in a short period of time.

[0003] While existing drainage systems for vulnerable slopes can remove water and reduce water accumulation, rainwater seeps into the slope soil, altering the seepage field. This increases the dynamic and static water loads on the soil, reduces its shear strength, increases its moisture content, and generates seepage forces, all of which reduce slope stability and lead to landslides. Therefore, this application provides a drainage system for vulnerable slopes and its installation method to meet this requirement. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drainage system for fragile slopes and a method for setting it up, so as to solve the problem of poor drainage effect of existing slopes when the rainfall is large.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A drainage system for vulnerable slopes includes a water storage tank, the bottom of which is fixed to the slope. Inverted "U"-shaped drainage pipes are installed on both sides of the water storage tank, with the top of the drainage pipes lower than the top of the water storage tank. One end of the drainage pipe is located above the bottom of the water storage tank, and the other end of the drainage pipe passes through the side wall of the water storage tank and is fixedly connected to a connecting plate. The connecting plate is fixedly connected to one end of a drainage board. The bottom of the drainage board is embedded in a straight groove on the vulnerable slope. A drainage channel is formed in the drainage board, and a placement groove is provided on one side of the drainage channel. A drive plate is fixedly connected to one side of the drainage board. A power component is rotatably connected to the drainage board, and the power component is used to drive the rotation of a protection component. The top of the drive plate is engaged with a protection component, which is used to protect the vulnerable slope.

[0007] Optionally, the power assembly includes a power shaft, with transmission belts sleeved on both sides of the power shaft, and the other end of the transmission belts sleeved on a reciprocating lead screw.

[0008] Optionally, a drive wheel is fixedly connected to one side of the drive shaft, and one end of a spiral spring is fixedly connected to the other end of the drive shaft. The other end of the spiral spring is fixedly connected to the inside of the mounting box. The mounting box is rotatably connected to the drive shaft. A set of circular arrays of spring-loaded steel balls are arranged around the periphery of the mounting box, and a spring is provided at the bottom of the spring-loaded steel balls.

[0009] Optionally, the drive wheel is rotatably connected to the drainage groove, the transmission belt is rotatably connected to the placement groove, a limiting ring is provided on one side of the drainage plate, a set of annular array limiting grooves are opened on the inner wall of the limiting ring, an installation box is provided in the limiting ring, and the top of the rebound steel ball is located in the limiting groove of the limiting ring.

[0010] Optionally, the protective assembly includes a protective plate, in which a pressing plate is slidably connected, an extension plate is slidably connected to the top of the protective plate, and a drive shaft is rotatably connected to the protective plate.

[0011] Optionally, a slide rod is fixedly connected to the protective plate, one end of the extrusion plate is slidably connected to the slide rod, and a T-shaped block is provided on the top of the protective plate.

[0012] Optionally, the other end of the extrusion plate is slidably connected to a reciprocating lead screw, which is rotatably connected to a protective plate.

[0013] Optionally, the top of the drive plate is provided with a set of evenly spaced serrated structures, one end of the drive shaft is provided with a gear, the drive shaft is meshed with the drive plate through the gear, and the middle part of the drive shaft is provided with an annular serrated structure.

[0014] Optionally, a T-slot is provided at the bottom of the extension plate, and a T-shaped block at the top of the protective plate is slidably connected in the T-slot. Toothed plates are provided on both sides of the T-slot, and the toothed plates are meshed with the middle part of the drive shaft.

[0015] This application also provides a method for setting up a drainage system for fragile slopes, including the following steps:

[0016] S1. Excavate a platform above the fragile slope, fix the bottom of the reservoir on the platform, and excavate straight trenches on both sides below the reservoir, and bury the bottom of the drainage board in the straight trenches.

[0017] S2. Determine the length of the straight trench so that the length of the drainage board buried in the straight trench is appropriate, and so that the tail end of the drainage board can be connected to the drainage ditch at the bottom of the fragile slope.

[0018] S3. Set up an appropriate number of power components and protection components according to the length of the vulnerable slope;

[0019] S4. When rainfall is low, the drainage board can drain some of the rainwater into the drainage ditch at the bottom of the vulnerable slope.

[0020] S5. During periods of heavy rainfall, the protective components can cover the surface of the vulnerable slope while simultaneously draining water from the surface of the vulnerable slope.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above scheme, by setting up a power component, the protection component can be controlled to protect the corresponding area on the slope when the rainfall is heavy, so as to prevent rainwater from damaging the slope. When the rainfall is light, the protection component will not rotate, so that the slope can remain stable under the infiltration of light rainfall, thereby protecting the slope. Furthermore, when the rainfall is heavy, the power of the water flow can be used to make the protection component protect the slope, thus saving resources.

[0023] By installing protective components, when rainfall is low, the components can remain perpendicular to the slope, allowing the slope to be soaked by rainwater. When rainfall is high, the components can not only cover the surface of the slope to block the impact of rainwater, but also press down on the slope to flatten it and squeeze out excess water, thus preventing excessive water accumulation on the slope and protecting it.

[0041] like Figures 1-4As shown, an embodiment of the present invention provides a drainage system for a fragile slope, including a water storage tank 1. The bottom of the water storage tank 1 is fixed to the slope. Inverted "U"-shaped drainage pipes 11 are provided on both sides of the water storage tank 1. The top of the drainage pipes 11 is lower than the top of the water storage tank 1. One end of the bottom of the drainage pipe 11 is located above the bottom of the water storage tank 1. The other end of the drainage pipe 11 passes through the side wall of the water storage tank 1 and is fixedly connected to a connecting plate 12. The connecting plate 12 is fixedly connected to one end of a drainage board 2. The bottom of the drainage board 2 is buried in a straight groove on the fragile slope. A drainage channel 21 is formed in the drainage board 2. A placement groove 22 is provided on one side of the drainage channel 21. A drive plate 3 is fixedly connected to one side of 2. When setting up this system, first dig out a platform of appropriate size on the slope and flatten and compact the platform. Then place and fix the water storage tank 1 on the top of the platform. Then dig a straight trench on each side of the water storage tank 1 and bury the bottom of the drainage board 2 in the straight trench so that the drainage board 2 can be fixed on the slope. When the rainfall is small, the rainwater can humidify the slope. When the rainfall is large, the impact of the rainwater on the slope will be more serious, thereby damaging the stability of the slope. At this time, the protection component 5 can protect the surface of the slope and prevent the surface of the slope from being damaged.

[0042] In this embodiment, as Figures 1-4 As shown, when it rains, the water storage tank 1 collects rainwater. When the rainfall is heavy, the liquid level inside the water storage tank 1 will rise. When the liquid level exceeds the highest point of the drain pipe 11, the water in the water storage tank 1 will enter the drainage trough 21 of the drainage board 2 through the drain pipe 11 under the siphon principle, and finally be discharged into the drainage ditch at the bottom of the slope.

[0043] As one implementation method in this embodiment, such as Figures 4-6As shown, a power assembly 4 is rotatably connected to the drainage plate 2. The power assembly 4 drives the rotation of the protection assembly 5. The power assembly 4 includes a power shaft 41, with transmission belts 42 sleeved on both sides of the power shaft 41. The other end of the transmission belts 42 is sleeved on a reciprocating screw 43. A power wheel 411 is fixedly connected to one side of the power shaft 41, and one end of a spiral spring 412 is fixedly connected to the other end of the power shaft 41. The other end of the spiral spring 412 is fixedly connected to the inside of the mounting box 413. The mounting box 413 is rotatably connected to the power shaft 41. A set of circular arrays of spring-loaded steel balls 414 are arranged around the periphery of the mounting box 413. A spring is provided at the bottom of the spring-loaded steel balls 414. The power wheel 411 is rotatably connected to the drainage groove 21. The transmission belts 42... The drainage plate 2 is rotatably connected in the placement groove 22. A limiting ring 23 is provided on one side of the drainage plate 2. A set of limiting grooves in a ring array are opened on the inner wall of the limiting ring 23. An installation box 413 is provided in the limiting ring 23. The top of the rebound steel ball 414 is located in the limiting groove of the limiting ring 23. When the rainfall is small, the rainwater can moisten the soil on the slope and keep the slope stable. When the rainfall is large, the liquid level in the water storage tank 1 will increase rapidly. When the liquid level in the water storage tank 1 rises above the drainage pipe 11, the water in the water storage tank 1 will enter the drainage trough 21 through the drainage pipe 11. Since the slope has a large inclination, the rainwater entering the drainage trough 21 will impact the power wheel 411 equipped with fan blades.

[0044] The flowing water causes the drive wheel 411 to rotate. When the drive wheel 411 rotates, it causes the drive shaft 41 to rotate. The drive shaft 41 then drives the reciprocating screws 43 on both sides to rotate via the transmission belt 42. Simultaneously, as the drive shaft 41 rotates, the mounting box 413 is held in the limit ring 23 by the return steel ball 414. Therefore, the drive shaft 41 rotates one end of the spiral spring 412. When one end of the spiral spring 412 rotates, the spiral spring 412 undergoes bending elastic deformation, causing the spring to twist in the plane. As the drive shaft 41 continues to bend the spiral spring 412, the spiral spring 412 also… The mounting box 413 will simultaneously generate a certain elastic force, and the mounting box 413 will also apply force to the rebound steel ball 414. When the elastic force reaches a certain level, the mounting box 413 will press the rebound steel ball 414 into the mounting box 413. At this time, the mounting box 413 will rotate in the limiting ring 23. When the water in the water tank 1 is drained, the power shaft 41 will not rotate under the action of the water flow. At this time, the rebound steel ball 414 will be locked in the limiting groove on the inner wall of the limiting ring 23 under the action of the bottom spring. The mounting box 413 will stop rotating in the limiting ring 23, and the spiral spring 412 will also twist in the opposite direction, causing the power shaft 41 to rotate in the opposite direction.

[0045] In this embodiment, as Figures 4-6As shown, the friction between the transmission belt 42, the power shaft 41, and the reciprocating screw 43 is relatively large, and the transmission belt 42 will not slip when it rotates.

[0046] As one implementation method in this embodiment, such as Figure 1 and Figures 7-8 As shown, a protective assembly 5 is engaged with the top of the drive plate 3. The protective assembly 5 is used to protect the fragile slope. The protective assembly 5 includes a protective plate 51, a pressing plate 52 slidably connected in the protective plate 51, an extension plate 53 slidably connected to the top of the protective plate 51, a drive shaft 54 ​​rotatably connected in the protective plate 51, and a slide rod 511 fixedly connected in the protective plate 51. One end of the pressing plate 52 is slidably connected to the slide rod 511. A T-shaped block is provided on the top of the protective plate 51, and the other end of the pressing plate 52 is slidably connected to a reciprocating screw 43. 43 is rotatably connected to the protective plate 51. The top of the drive plate 3 is provided with a set of evenly spaced sawtooth structures. One end of the drive shaft 54 ​​is provided with a gear, and the drive shaft 54 ​​is meshed with the drive plate 3 through the gear. The middle part of the drive shaft 54 ​​is provided with an annular sawtooth structure. The bottom of the extension plate 53 is provided with a T-shaped groove 531, and the T-shaped block on the top of the protective plate 51 is slidably connected in the T-shaped groove 531. Both sides of the T-shaped groove 531 are provided with toothed plates 532, and the toothed plates 532 are meshed with the middle part of the drive shaft 54. When the rainfall is large... When the water in the reservoir 1 enters the drainage trough 21 through the drain pipe 11, it causes the power shaft 41 to rotate, thereby causing the reciprocating screw 43 to rotate. When the reciprocating screw 43 rotates, the extrusion plate 52 rotates and touches the ground. Since one end of the extrusion plate 52 is slidably connected to the slide rod 511 of the protective plate 51, the protective plate 51 will rotate synchronously with the extrusion plate 52 and touch the ground. During the rotation of the protective plate 51, the transmission shaft 54 ​​will rotate under the action of the arc-shaped drive plate 3. When the transmission shaft 54 ​​rotates... When the drive shaft 54 ​​moves the toothed plate 532, the extension plate 53 can gradually extend. When the protective plate 51 rotates to the ground, the extension plate 53 stops moving. When the pressing plate 52 rotates and sticks to the slope, due to the obstruction of the slope, the rotating reciprocating screw 43 can only make the pressing plate 52 move back and forth on the ground. During the reciprocating movement of the pressing plate 52, not only can the excess water on the slope be pushed to both sides, but the water inside the slope surface can also be squeezed out and pushed to both sides, thus protecting the slope.

[0047] In this embodiment, as Figure 1 and Figures 7-8As shown, when the reciprocating screw 43 rotates in the reverse direction, the transmission shaft 54 ​​will rotate in the reverse direction on the drive plate 3, and drive the toothed plate 532 to move in the reverse direction, so that the extension plate 53 can automatically retract when the protective plate 51 rotates in the reverse direction. When the protective plate 51 stops rotating, when the bottom surface of the protective plate 51 touches the slope, the protective plate 51 will stop rotating under the obstruction of the slope, and the protective plate 51 will return to the state perpendicular to the slope. At this time, the pressing plate 52 will slide on the protective plate 51 under the action of the rotating reciprocating screw 43 until the reciprocating screw 43 stops rotating.

[0048] like Figures 1-4 As shown, an embodiment of the present invention provides a method for setting up a drainage system for a fragile slope, comprising the following steps:

[0049] S1. Excavate a platform above the fragile slope, fix the bottom of the water storage tank 1 on the platform, and excavate straight trenches on both sides below the water storage tank 1, and bury the bottom of the drainage board 2 in the straight trenches.

[0050] S2. Determine the length of the straight trench so that the length of the drainage board 2 buried in the straight trench is appropriate, so that the tail end of the drainage board 2 can be connected to the drainage ditch at the bottom of the fragile slope.

[0051] S3. Based on the length of the vulnerable slope, install an appropriate number of power components 4 and protection components 5;

[0052] S4. When the rainfall is low, the drainage board 2 can drain some of the rainwater into the drainage ditch at the bottom of the fragile slope.

[0053] S5. When rainfall is heavy, the protective component 5 can cover the surface of the vulnerable slope and drain the water from the surface of the vulnerable slope.

[0054] The working principle provided by this invention is as follows: When setting up this system, firstly, a platform of suitable size is excavated on the slope, and the platform is leveled and compacted. Next, a water storage tank 1 is placed and fixed on top of the platform. Then, a straight trench is excavated on each side of the water storage tank 1, and the bottom of the drainage board 2 is buried in the trench, allowing the drainage board 2 to be fixed to the slope. When rainfall is light, rainwater can humidify the slope. When rainfall is heavy, the impact of rainwater on the slope is more severe, thus damaging the slope's stability. At this time, the protective component 5 can protect the slope surface, preventing damage. When rainfall is light, rainwater can moisten the soil on the slope, keeping the slope stable. When rainfall is heavy... When the water level in the reservoir 1 rises rapidly, and the water in the reservoir 1 enters the drainage trough 21 through the drainage pipe 11, the water level in the reservoir 1 will rise rapidly. Due to the large slope of the slope, the rainwater entering the drainage trough 21 will impact the drive wheel 411 equipped with fan blades. The flowing water will cause the drive wheel 411 to rotate. When the drive wheel 411 rotates, it will cause the drive shaft 41 to rotate. At this time, the drive shaft 41 will drive the reciprocating screws 43 on both sides to rotate through the transmission belt 42. At the same time, when the drive shaft 41 rotates, because the mounting box 413 is locked in the limit ring 23 by the spring ball 414, the drive shaft 41 will rotate one end of the spiral spring 412. When one end of the spiral spring 412 rotates, the spiral spring 412 undergoes bending elastic deformation, causing the spring to twist in the plane. As the power shaft 41 continues to bend the spiral spring 412, the spiral spring 412 also generates a certain elastic force in the mounting box 413. The mounting box 413 also applies force to the return steel ball 414. When the elastic force reaches a certain level, the mounting box 413 will press the return steel ball 414 into the mounting box 413. At this time, the mounting box 413 will rotate in the limiting ring 23. When the water in the water tank 1 has drained, the power shaft 41 will no longer rotate under the action of the water flow. At this time, the return steel ball 414 will be re-locked in the limiting groove on the inner wall of the limiting ring 23 under the action of the spring at the bottom. The rotation will stop within the limit ring 23, and the spiral spring 412 will also twist in the opposite direction, causing the power shaft 41 to rotate in the opposite direction. When the rainfall is heavy, the water in the reservoir 1 will enter the drainage trough 21 through the drain pipe 11, causing the power shaft 41 to rotate, which in turn causes the reciprocating screw 43 to rotate. When the reciprocating screw 43 rotates, the pressing plate 52 will rotate and touch the ground. Since one end of the pressing plate 52 is slidably connected to the slide rod 511 of the protective plate 51, the protective plate 51 will rotate synchronously with the pressing plate 52 and touch the ground. During the rotation of the protective plate 51, the transmission shaft 54 ​​will rotate under the action of the arc-shaped drive plate 3. When the transmission shaft 54 ​​rotates, it will cause the toothed plate 532 to move.This allows the extension plate 53 to gradually extend. When the protective plate 51 rotates to the ground, the extension plate 53 stops moving. When the pressing plate 52 rotates and adheres to the slope, due to the obstruction of the slope, the rotating reciprocating screw 43 can only cause the pressing plate 52 to move back and forth on the ground. During the reciprocating movement of the pressing plate 52, not only can excess water on the slope be pushed to both sides, but water inside the slope surface can also be squeezed out and pushed to both sides, thus protecting the slope.

[0055] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0056] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
