Description

Technical Field

[0001] This utility model relates to an arc-shaped flow-dissipating sill type riverbank protection device. Background Technology

[0002] Currently, the revetment works at locations with rapid river flow and bends are constructed using masonry and cast-in-place concrete, lacking pre-cast concrete arc-shaped flow-dissipating sills for energy dissipation. The existing revetments are in the form of vertical or sloping walls, which have smooth surfaces and are suitable for irrigation channels. However, they present technical problems for revetment at locations with rapid river flow and bends. They lack energy dissipation capabilities, do not conform to fluid mechanics, and cause the water flow impact force to be directed downstream, reducing the effectiveness of the revetment. Furthermore, there is a lack of space for placing flood control and drowning prevention equipment.

[0003] In addition, the existing riverbank protection structures present problems in terms of human-centered design, as people who accidentally fall are difficult to return to shore due to the slippery riverbank, whether it is a vertical wall or a smooth sloping wall. They also lack technical design for emergency rescue. Utility Model Content

[0004] To overcome the shortcomings of the aforementioned bank protection technologies, such as lack of pre-cast concrete, lack of energy dissipation function, non-compliance with fluid mechanics, and lack of human-centered design, this utility model provides an arc-shaped flow-dissipating sill energy-dissipating riverbank protection device applicable to turbulent waterways and bends. It uses pre-cast thin-walled concrete, has an arc-shaped flow-dissipating sill to eliminate the impact kinetic energy of the water flow, and an arc-shaped wall structure that conforms to fluid mechanics, converting some of the water's kinetic energy into potential energy and reducing water energy in the process. It also features ergonomic climbing foot pedals and handholds, a human-centered design, locations for placing flood control and drowning prevention equipment, and emergency rescue functions.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an arc-shaped flow-dissipating sill-type riverbank protection device, including a base, an arc-shaped wall, an arc-shaped flow-dissipating sill, main ribs, secondary ribs, a wall top, screw connection holes, connecting protrusions, connecting grooves, a first lifting hole, a first guardrail reserved hole, a second guardrail reserved hole, a second lifting hole, a toothed wall, climbing steps, climbing grips, seepage holes, hooks, a first lifting hook, a second lifting hook, and a top climbing grip. It adopts a thin-walled reinforced concrete structure, with hooks connected below the top of the wall. The arc-shaped wall and the arc-shaped flow-dissipating sill are arc-shaped. Climbing steps, climbing grips, and a top climbing grip are set on the arc-shaped flow-dissipating sill. It is a humanized design. The base is connected to the arc-shaped wall, and the arc-shaped wall is connected to the arc-shaped flow-dissipating sill. The arc-shaped wall and the arc-shaped flow-dissipating sill together constitute the arc-shaped flow-dissipating riverbank protection device.

[0006] The aforementioned arc-shaped flow-dissipating sill type riverbank protection device has a base connected to an arc-shaped wall at the top, with an arc-shaped flow-dissipating sill connecting the two on the water-facing side and a main rib and a secondary rib connecting the two on the water-repelling side. After the connection, it has a reinforcing effect on the connection between the base and the arc-shaped wall, and the arc-shaped flow-dissipating sill itself has a water flow dissipating effect.

[0007] The aforementioned arc-shaped flow-dissipating sill type riverbank protection device has a base connected to the bottom of the arc-shaped wall and a wall top connected to the top of the base. The concave side is the water-facing side, and arc-shaped flow-dissipating sills are connected to the left and right sides of the concave side. The convex side is the water-repellent side, and the convex side is connected to the main rib and the secondary rib. Small-diameter seepage holes are provided below the arc-shaped wall, distributed in a plum blossom pattern, mainly to discharge water pressure in the convex riverbank and embankment soil layer.

[0008] The aforementioned arc-shaped flow-dissipating sill type riverbank protection device has an arc-shaped wall connected to the top of the wall, with the top of the arc-shaped flow-dissipating sill connected to the left and right sides of the water-facing side, and the top of the main rib connected to the back side of the wall. Each of the left and right shoulders is connected to a top climbing grab. The middle position is connected to the first hoisting hole, the first guardrail reserved hole, the second guardrail reserved hole, and the second hoisting hole. The lower middle part is connected to a hook.

[0009] The aforementioned arc-shaped flow-dissipating sill-type riverbank protection device has an arc-shaped flow-dissipating sill connected to a wall top at the top, a base at the bottom, and an arc-shaped wall in the middle. Climbing steps and grab handles are connected to it at equal intervals, and the screw connection holes are located in the lower part of the sill. When the bank protection height is greater than 2 meters, the arc-shaped wall and arc-shaped flow-dissipating sill are inclined, and the connection points with other parts are adjusted accordingly. The wall top, base, arc-shaped wall, and toothed wall are designed to be curved in the river bends, with reinforced concrete pre-cast along the river bend, similar to a pipe bend, while other settings remain unchanged.

[0010] The aforementioned arc-shaped flow-dissipating sill type riverbank protection device has a main rib connected to the top of the wall above, a base below, and an arc-shaped wall in the middle. The secondary rib is connected to the arc-shaped wall above and the base below. The main and secondary ribs mainly increase the pressure resistance of the arc-shaped wall and increase the contact area with the soil layer, thereby increasing the stability of the device.

[0011] The aforementioned arc-shaped flow-dissipating sill-type riverbank protection device has a screw connection hole located in the lower part of the arc-shaped flow-dissipating sill. This hole is used to connect other arc-shaped flow-dissipating sill-type riverbank protection devices via screws, and can also be used as a hoisting hole during installation. The connecting protrusion is connected to the middle of the arc-shaped wall and arc-shaped flow-dissipating sill on one side, and the connecting groove is connected to the middle of the arc-shaped wall and arc-shaped flow-dissipating sill on the other side. When the two devices are combined, the connecting protrusion and the connecting groove interlock, leaving a 2-centimeter gap between them.

[0012] The aforementioned arc-shaped flow-dissipating sill-type riverbank protection device has two hoisting holes: the first and second hoisting holes are located above the top of the wall and are used for hoisting the device. After hoisting, they can be used to install guardrails and insert rescue poles. The first and second guardrail pre-reserved holes are also located above the top of the wall and are used for hoisting the device. After hoisting, they are mainly used for installing guardrails, a human-centered design that prevents drowning. The toothed wall is connected to the base and its main function is to ensure a tight bond between the device and the soil layer, increasing the stability of the device. The climbing steps, climbing grips, and top climbing grips are concave grooves. The climbing steps and climbing grips are grooved and connected to the arc-shaped flow-dissipating sill, and the top climbing grips are grooved and connected to the two shoulders of the top of the wall. When the two devices are combined, the climbing steps, climbing grips, and top climbing grips on the two devices form a ladder-like combination for coordinated use.

[0013] The aforementioned arc-shaped flow-dissipating sill-type riverbank protection device has seepage holes located at the bottom of the arc-shaped wall, distributed in a quincunx pattern, with a diameter of 1 cm. The hooks are connected to the center below the top of the wall and are used to suspend emergency equipment such as life ropes and life rings. The first and second lifting hooks are made of steel and are fixedly connected to the base. Their roots should be lengthened and widened and firmly connected to the base reinforcement. During the design, the combined force between the two lifting hooks and the base should exceed the tensile force generated during lifting.

[0014] The beneficial effects of this utility model are as follows: when water flows over the revetment, this device can effectively reduce the water velocity while protecting the embankment. The arc-shaped wall conforms to fluid mechanics and can convert some of the water's kinetic energy into potential energy, thereby reducing water energy. The arc-shaped flow-dissipating sill eliminates the impact kinetic energy of the water flow, achieving a force dissipation effect and reducing hydraulic erosion of the downstream river channel, thus playing a role in soil and water conservation. It enhances the function of removing the impact force of water flow compared to existing technologies. The whole is made of precast reinforced concrete, which can be used for emergency hoisting and reinforcement of embankments and dams in the event of rainfall caused by extreme weather. This improves the reinforcement efficiency compared to traditional stone-pile embankment reinforcement, achieving twice the result with half the effort. The addition of an emergency rescue design, including climbing ramps, climbing grips, and hooks, provides effective rescue capabilities, and its long-term significance is important.

[0028]

Example 1

[0029] First, prepare the foundation for the revetment, ensuring it is solid and level. Then, prepare for hoisting by threading one end of the hoisting rope through the [unclear - likely a specific point in the text]. Figure 1 As shown, first hoisting hole 10 on the far left, then insert the first hoisting hook 19 on the left, ensuring a secure connection. Pass the other end of the hoisting rope through the second hoisting hole 13 on the far right, then insert it through the second hoisting hook 20 on the right, ensuring a secure connection to form a closed loop. Then take another hoisting rope, pass it downwards through the first guardrail pre-drilled hole 11 on the left, and then upwards through the second guardrail pre-drilled hole 12 on the right, forming a closed loop. Use these two hoisting ropes for hoisting, first hoisting at the beginning of the revetment foundation. After one device is hoisted, hoist the next device in sequence. For example... Figure 7 As shown, when two adjacent devices are combined, the connecting protrusion 8 and the connecting groove 9 engage together, leaving a 2-centimeter gap between them. If the gap is too small, it will be too difficult to connect them. After the rough connection is completed, screws are passed through the screw connection hole 7 to reinforce the connection. The devices are then connected to each other to form a whole and protect the dike.

[0030]

Example 2

[0031] On the side of the device closest to the shore, backfill and compact the soil, such as... Figure 3 As shown, the toothed wall 14, along with the main rib 4 and secondary rib 5, extends into the earthwork, serving to achieve a close connection with the embankment.

[0032]

Example 3

[0033] When water flows through the device, the curved wall 2, with its curved shape, conforms to fluid mechanics. Under the diversion effect of the curved diversion sill 3, the water flows up along the curved wall 2, which can convert some of the water's kinetic energy into potential energy. In the process, the impact energy of the water flow is reduced, which can have a slowing effect on the water flow. The diversion effect of the curved diversion sill 3 also effectively reduces the water flow velocity. The combination of the above two effectively reduces the impact of floods on the dikes and slows down the impact on the downstream river dikes.

[0034]

Example 4

[0035] like Figure 9 As shown, when adjacent devices are connected together, the adjacent arc-shaped sills 3 are combined together, and the climbing steps 15, climbing grips 16, and top climbing grips 21 are combined to form a climbing ladder, which is used for emergency rescue and for clearing river silt.

[0036]

Example 5

[0037] This device has a prominent emergency rescue function. Hook 18 is used to suspend emergency equipment such as life ropes and life rings. One end of the rescue rope should hang below the base. In case of a rescue, the person in the water should first attempt self-rescue by grabbing the rescue rope on hook 18, the first hoisting hook 19, the second hoisting hook 20, or the climbing handrail 16 to climb onto the base 1. Then, they can ascend the curved sill 3 along the climbing steps 15 and the climbing handrail 16 to the top of the wall 6 and successfully rescue themselves. In another scenario, if the person in the water cannot reach the shore, and someone on the shore discovers them, they should bend down to retrieve the rescue rope and throw it to the person in the water. Alternatively, when there is a person in the water, rescuers can descend along the climbing steps 15 and the climbing handrail 16 to the base 1 to retrieve the life rope suspended on hook 18, enter the water to rescue them, and then ascend along the climbing steps 15 and the climbing handrail 16 to the shore. Hanging emergency rescue equipment below the ceiling helps protect it from direct sunlight and prevents unsuspecting children from touching it.

[0038]

Example 6

[0039] When the soil on the bank exceeds the saturation level and seepage occurs, the water flows out through the small holes of the seepage holes 17 of this device. The small holes retain the mud and sand and seep out the clear water, which is beneficial to soil and water conservation.

[0040]

Example 6

[0041] like Figure 10 As shown, when the revetment height is greater than 2 meters, a sloping revetment should be used. Figure 11 As shown, the design at the bend of the river channel adopts a curved design.
