Description

Technical Field

[0001] This invention relates to the field of rockfall collection and rainwater irrigation technology, specifically to a device for preventing rockfalls, collecting rainwater, and irrigating the land, and its construction method. Background Technology

[0002] Slope protection refers to the construction of a protective layer on the surface of a slope to prevent secondary disasters such as spalling, rockfalls, collapses, landslides, and debris flows caused by natural factors such as wind erosion, rain erosion, gravity, and freeze-thaw cycles. Slope protection is an important part of roadbed slope protection and is a common area prone to roadbed defects during railway operation.

[0003] In existing technologies, such as the device and construction method for collecting rainwater for rockfall prevention and irrigation (Chinese Patent No. CN113006096B), a slope with a top surface, an incline, and a bottom surface is included. Concrete layers are poured on the top, incline, and bottom surfaces of the slope. A top water trough is formed on the top concrete layer, and a bottom water trough is formed on the bottom concrete layer. Filter screens are fixedly installed in both the top and bottom water troughs. A water storage tank is fixedly installed within the slope, and a water pump is fixedly installed inside the tank. A drain pipe is fixedly installed between the top water trough and the water storage tank, and a guide pipe is fixedly installed between the bottom water trough and the water storage tank. The advantages are: it not only provides high protection but also diverts and collects rainwater, and the collected rainwater can be used to irrigate and maintain vegetation on the slope without requiring manual watering, resulting in high water resource utilization.

[0004] However, while the aforementioned patents have the above-mentioned technical advantages, the disadvantages of traditional slope protection equipment are that, when in use, they can only intercept falling gravel through straight plates. The straight plates have a straight surface structure, and the falling gravel directly impacts the outer surface of the plates. The direction of the force is perpendicular to the plate surface. Because the gravel is suddenly intercepted, the force of the gravel acts directly on the equipment, making the equipment very easy to be damaged by impact. In order to improve the stability of the equipment, vegetation is usually added to the gaps between the equipment. However, a large amount of vegetation needs to be watered regularly during its subsequent growth, which is time-consuming and labor-intensive. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is: a device for preventing rockfalls and collecting rainwater for irrigation, comprising a connecting device, a blocking device at the top of the connecting device, the blocking device comprising an arc-shaped plate, a water-draining groove formed in the wall of the arc-shaped plate, a base provided outside the water-draining groove, a concave plate fixedly connected to the lower surface of the base, and a water outlet groove formed in the wall of the concave plate. When gravel from the top of the slope rolls down, after passing the arc-shaped plate, the gravel rolls along the outer surface of the arc-shaped plate. By increasing the height of the top of the arc-shaped plate, kinetic energy is converted into gravitational potential energy, thus slowing down the impact force of the falling gravel.

[0006] The connecting device includes a pad, an inner rod is provided inside the pad, an outer rod is slidably connected to the outer surface of the inner rod, a compression spring is provided outside the outer rod, a counterweight device is provided on the top of the compression spring, and a locking block is provided outside the counterweight device. The base is squeezed and deformed to buffer the impact of the arc plate on the concave plate. When it rains outside, the rainwater rolls down the arc along the outer surface of the arc plate.

[0007] In a preferred embodiment, the upper surface of the base is fixedly connected to the lower surface of the arc-shaped plate, and the lower surface of the arc-shaped plate is fixedly connected to the upper surface of the concave plate. The water outlet is symmetrically opened, and the water falls from the water outlet into the interior of the concave plate until the rainwater level covers the water outlet, and the water flows out to irrigate the vegetation.

[0008] In a preferred embodiment, the upper surface of the pad is fixedly connected to the lower surface of the counterweight device, the inner surface of the locking block is engaged with the outer surface of the pad, the top end of the compression spring is fixedly connected to the lower surface of the pad, the upper surface of the pad is fixedly connected to the lower surface of the concave plate, the inner surface of the pad is slidably connected to the outer surface of the outer rod, the outer surface of the outer rod is slidably connected to the inner surface of the concave plate, the lower surface of the pad is in contact with the slope protection, and the locking block is embedded in the ground. By increasing the contact area and depth, the friction is increased, preventing relative sliding between the pad and the slope protection.

[0009] In a preferred embodiment, the counterweight device includes a hollow plate with a rectangular groove in its wall. A partition is provided outside the rectangular groove, and a cement chamber is provided outside the partition. The cement chamber inside the counterweight device is filled with concrete to increase the contact pressure between the hollow plate and the slope protection, thereby further increasing stability.

[0010] In a preferred embodiment, the cement chamber is formed within the wall of a hollow slab. The outer surface of the hollow slab is fixedly connected to the outer surface of the partition. Vegetation is planted on the other side of the partition. The roots of the vegetation penetrate into the soil of the slope protection through rectangular grooves. Water flows out from the water outlet to irrigate the vegetation, eliminating the need for regular manual maintenance. The outer rod is impacted downwards, and the triangular block is inserted into the interior of the tunnel. The compression spring extends, and the pin slides obliquely downwards along the interior of the chute. The oblique rod rotates, forcing the two ends of the pad to bend.

[0011] In a preferred embodiment, a triangular block is provided at the bottom of the pad, and a diagonal rod is slidably connected to the top of the triangular block via a pin. A groove is provided in the wall of the diagonal rod. A pressure plate is slidably connected to the inner surface of the triangular block, and a rubber plate is provided at the bottom of the pressure plate. A diagonal plate is fixedly connected to the lower surface of the rubber plate. Then, the inner rod continues to press down, and the pressure plate slides down along the inner surface of the triangular block. By squeezing the hydraulic oil at the bottom of the pressure plate, the rubber plate is forced to bend and deform.

[0012] In a preferred embodiment, the top end of the inclined rod is rotatably connected to the lower surface of the pad, the bottom end of the inclined rod is rotatably connected to the outer surface of the triangular block, the outer surface of the pin is fixedly connected to the outer surface of the triangular block, the bottom end of the compression spring is fixedly connected to the upper surface of the triangular block, the upper surface of the triangular block is fixedly connected to the bottom end of the outer rod, the upper surface of the pressure plate is fixedly connected to the bottom end of the inner rod, the outer surface of the inner rod is slidably connected to the inner surface of the triangular block, the inner surface of the triangular block is slidably connected to the outer surface of the inclined plate, and the inner surface of the triangular block is fixedly connected to the outer surface of the rubber plate. The bent rubber plate pushes the inclined plate to insert obliquely into the ground. When the entire equipment moves upward, the exposed inclined plate prevents the triangular block from being pulled out from the inside of the slope protection, and the equipment has extremely high stability.

[0013] The construction method of the device for preventing rockfalls and collecting rainwater for irrigation includes the following steps:

[0014] Step 1: Dig holes on the outer surface of the slope protection and insert the connecting devices into the holes one by one. The connecting devices are arranged linearly inside the slope protection.

[0015] Step 2: Weld a blocking device to the top of the connecting device, leaving part of the equipment exposed and the other part buried;

[0016] Step 3: Pour concrete inside the cement chamber of the counterweight device, and plant vegetation in the space on the other side of the partition and the top of the rectangular trough.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. This invention incorporates a blocking device. When the equipment is in use, the gravel at the top of the slope rolls downwards. After passing the arc-shaped plate, the gravel rolls along the outer surface of the arc-shaped plate. By increasing the height of the top of the arc-shaped plate, kinetic energy is converted into gravitational potential energy, thus slowing down the impact of the falling gravel. The base is squeezed and deformed, buffering the impact of the arc-shaped plate on the concave plate. When it rains, rainwater rolls down the outer surface of the arc-shaped plate in an arc shape, falling from the drainage channel into the interior of the concave plate until the rainwater level covers the outlet channel, at which point the water flows out and irrigates the vegetation.

[0019] 2. This invention, through the setting of a connecting device, allows the lower surface of the pad to contact the slope protection when the equipment is in use. The locking block is embedded in the ground, increasing the contact area and depth to improve friction and prevent relative sliding between the pad and the slope protection. The cement chamber inside the counterweight device increases the contact pressure between the hollow slab and the slope protection by pouring concrete, further increasing stability. Vegetation is planted on the other side of the partition, and the roots of the vegetation penetrate into the soil of the slope protection through rectangular grooves. Water flows out from the water outlet groove to irrigate the vegetation, eliminating the need for regular manual maintenance.

[0020] 3. This invention utilizes a triangular block. When the equipment is in use, the outer rod is impacted downwards, causing the triangular block to insert into the interior of the tunnel. The compression spring extends, and the pin slides diagonally downwards along the interior of the groove. The diagonal rod rotates, forcing the two ends of the pad to bend. Subsequently, the inner rod continues to press down, and the pressure plate slides downwards along the inner surface of the triangular block. By squeezing the hydraulic oil at the bottom of the pressure plate, the rubber plate is forced to bend and deform. The bent rubber plate pushes the inclined plate diagonally into the ground. When the entire equipment moves upwards, the exposed inclined plate prevents the triangular block from being pulled out from the interior of the slope protection, giving the equipment extremely high stability.

The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0031] The gravel at the top of the slope rolls down and, after passing the arc-shaped plate 3, rolls along the outer surface of the arc-shaped plate 3. By increasing the height of the top of the arc-shaped plate 3, kinetic energy is converted into gravitational potential energy, which slows down the impact of the gravel rolling down. The base 5 is squeezed and deformed to buffer the impact of the arc-shaped plate 3 on the concave plate 6. When it rains, the rainwater rolls down the outer surface of the arc-shaped plate 3 in an arc shape and falls from the drainage trough 4 into the interior of the concave plate 6 until the rainwater level covers the outlet trough 7, and the water flows out to irrigate the vegetation.

A rubber plate 25 is provided at the bottom of the pressure plate 24, and a diagonal plate 26 is fixedly connected to the lower surface of the rubber plate 25.

[0033] The lower surface of the pad 10 contacts the slope protection, and the locking block 15 is embedded in the ground. By increasing the contact area and depth, the friction is increased, preventing the pad 10 from sliding relative to the slope protection. The cement chamber 19 inside the counterweight device 14 increases the contact pressure between the hollow slab 16 and the slope protection by pouring concrete, further increasing stability. Vegetation is planted on the other side of the partition 18. The roots of the vegetation penetrate into the soil of the slope protection through the rectangular groove 17. Water flows out from the water outlet 7 to irrigate the vegetation, eliminating the need for regular manual maintenance.

[0034] The top end of the diagonal rod 21 is rotatably connected to the lower surface of the pad 10, the bottom end of the diagonal rod 21 is rotatably connected to the outer surface of the triangular block 20, the outer surface of the pin 23 is fixedly connected to the outer surface of the triangular block 20, the bottom end of the compression spring 13 is fixedly connected to the upper surface of the triangular block 20, the upper surface of the triangular block 20 is fixedly connected to the bottom end of the outer rod 12, the upper surface of the pressure plate 24 is fixedly connected to the bottom end of the inner rod 11, the outer surface of the inner rod 11 is slidably connected to the inner surface of the triangular block 20, the inner surface of the triangular block 20 is slidably connected to the outer surface of the diagonal plate 26, and the inner surface of the triangular block 20 is fixedly connected to the outer surface of the rubber plate 25.

[0035] The outer rod 12 is impacted downwards, the triangular block 20 is inserted into the interior of the tunnel, the compression spring 13 extends, the pin 23 slides obliquely downwards along the interior of the slide groove 22, the inclined rod 21 rotates, forcing the two ends of the pad 10 to bend, then the inner rod 11 continues to press down, the pressure plate 24 slides downwards along the inner surface of the triangular block 20, and by squeezing the hydraulic oil at the bottom of the pressure plate 24, the rubber plate 25 is forced to bend and deform. The bent rubber plate 25 pushes the inclined plate 26 to be inserted obliquely into the ground. When the entire equipment moves upwards, the exposed inclined plate 26 prevents the triangular block 20 from being pulled out from the interior of the slope protection, and the equipment has extremely high stability.

[0036] The construction method of the device for preventing rockfalls and collecting rainwater for irrigation includes the following steps:

[0037] Step 1: Dig pits on the outer surface of the slope protection, with a spacing of 1.5 meters between two adjacent pits. Insert the connecting device 1 into the pits one by one. The connecting device 1 is arranged linearly inside the slope protection.

[0038] Step 2: Weld the blocking device 2 to the top of the connecting device 1, so that part of the equipment is exposed and the other part is buried.

[0039] Step 3: Pour concrete inside the cement chamber 19 inside the counterweight device 14, and plant vegetation in the space on the other side of the partition 18 and the top of the rectangular groove 17.

[0040] Working principle:

[0041] When the equipment is in use, the gravel at the top of the slope rolls down and, after passing the arc plate 3, rolls along the outer surface of the arc plate 3. By increasing the height of the top of the arc plate 3, kinetic energy is converted into gravitational potential energy, which slows down the impact of the gravel rolling down. The base 5 is squeezed and deformed to buffer the impact of the arc plate 3 on the concave plate 6. When it rains, the rainwater rolls down in an arc along the outer surface of the arc plate 3 and falls from the drainage trough 4 into the interior of the concave plate 6 until the rainwater level covers the outlet trough 7, and the water flows out to irrigate the vegetation.

[0042] The lower surface of the pad 10 contacts the slope protection, and the locking block 15 is embedded in the ground. By increasing the contact area and depth, the friction is increased, preventing the pad 10 from sliding relative to the slope protection. The cement chamber 19 inside the counterweight device 14 increases the contact pressure between the hollow slab 16 and the slope protection by pouring concrete, further increasing stability. Vegetation is planted on the other side of the partition 18. The roots of the vegetation penetrate into the soil of the slope protection through the rectangular groove 17. Water flows out from the water outlet 7 to irrigate the vegetation, eliminating the need for regular manual maintenance.

[0043] The outer rod 12 is impacted downwards, the triangular block 20 is inserted into the interior of the tunnel, the compression spring 13 extends, the pin 23 slides obliquely downwards along the interior of the slide groove 22, the inclined rod 21 rotates, forcing the two ends of the pad 10 to bend, then the inner rod 11 continues to press down, the pressure plate 24 slides downwards along the inner surface of the triangular block 20, and by squeezing the hydraulic oil at the bottom of the pressure plate 24, the rubber plate 25 is forced to bend and deform. The bent rubber plate 25 pushes the inclined plate 26 to be inserted obliquely into the ground. When the entire equipment moves upwards, the exposed inclined plate 26 prevents the triangular block 20 from being pulled out from the interior of the slope protection, and the equipment has extremely high stability.
