Description

Technical Field

[0001] The invention relates to the fields of flood rescue and disaster relief and water conservancy project construction, and in particular to an anchor cable type interception and plugging device. Background Art

[0002] Levee breach is an important form of flood disaster. The location of the breach is uncertain and develops rapidly, which will cause serious losses to social and economic activities. At present, most of the breaches are completed in a quasi-static water state where the water surface inside and outside the levee is basically flat. From the beginning of the breach to the continuous expansion, the breach water flow is turbulent. It is extremely difficult to block it by traditional methods such as throwing stones and sandbags, and there are problems such as low blocking efficiency and easy to be washed away by water flow. When building permanent hydraulic structures such as dams and sluices on rivers, cofferdams are usually built first to ensure the normal construction of hydraulic structures. The construction of cofferdams requires intercepting the river flow. Traditional river interception technologies mostly use methods such as dam cofferdams, throwing large stones or concrete blocks, etc. In essence, river interception and levee breach blocking are consistent in principle, blocking materials, and method technology. There are three traditional river diversion technologies: vertical blocking, horizontal blocking and mixed blocking. Regardless of the technology used, there are high requirements for the thrown materials to prevent impact. The thrown materials that do not meet the requirements face the risk of interception failure and breach expansion. The strict screening of thrown materials means a lot of preliminary engineering preparation, a long construction period and economic cost.

[0003] At present, there are many improved methods for interception and breach sealing, including breach protection and the throwing method of plugging objects, etc., focusing on how to ensure that the breach does not develop and how to improve the sealing method. In fact, river breaches develop very quickly. Excessive reliance on engineering construction after the danger occurs will take a long time and can only be used for sealing after the breach widens and flooding losses. How to intercept and seal breaches at low cost and high efficiency under turbulent water conditions is an important problem currently faced by flood rescue and water conservancy project construction. Therefore, in order to avoid flooding losses and reduce interception costs to the greatest extent, it is particularly important to develop a technically feasible, economical and practical interception and breach sealing device. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes an anchor-type flow interception and plugging device.

[0005] The technical solution of the present invention is: an anchor-type intercepting and plugging device, comprising an anchor body, a plugging object and a rope, wherein several plugging objects are connected side by side to form an arched plugging body, the arched plugging body is arranged on the inner side of the breach or the river intercepting part, and is curved toward the upstream of the breach or the river, the two ends of the arched plugging body are respectively connected to the two sides of the breach or the river intercepting part, and the side parts of adjacent plugging objects in the arched plugging body contact each other to form a sealing structure; each plugging object is connected to a rope, and the adjacent ropes are evenly arranged radially upstream with the breach or the river intercepting part as the center, and the inner end of the rope is connected to the anchor body.

[0006] Preferably, the rope is a cable or a chain, and a rope buckle for adjusting the length of the rope is provided on the rope so that the rope is in a tensioned state between the anchoring body and the blocking object.

[0007] Preferably, the anchoring body is a metal anchor, which is sunk and anchored into the mud and sand at the bottom of the water body or anchored on the embankments on both sides to achieve anchoring.

[0008] Preferably, the anchoring body is a sandbag filled with mud and sand or a gabion filled with stone, and anchoring is achieved by the deadweight of the sandbag or the gabion.

[0009] Preferably, the plugging object is a stone-filled gabion or geotextile, which sinks to the bottom of the breach or river diversion site by its own gravity.

[0010] Preferably, the plugging object is a prefabricated component, which is an integral component matching the size of the breach or the river closure portion, or is a plurality of small components interconnected by a mechanical docking mechanism.

[0011] Preferably, the arched sealing bodies are arranged in a multi-layer stacking manner according to the depth of the breach or the river interception portion.

[0012] Preferably, the plugging objects are moved and stacked in the water body of the breach or the river diversion section by being bundled with floating objects for transportation.

[0013] Preferably, the anchor is transported by ship to the breach or the river diversion section for fixed-point throwing, and the lighter anchor is thrown over a long distance by a thrower or a drone.

[0014] The beneficial technical effect of the present invention is as follows: the present invention changes the traditional method of plugging the breach by throwing back filling materials into an anchor-type plugging method, thereby avoiding the problem that the plugging material cannot stagnate at the breach because its own gravity is insufficient to resist the drag force of the water flow. The rope and the plugging material are connected by a snap hook. After the plugging is completed, the rope and the anchor body can be recovered, or the anchor-type plugging device can be used for preliminary cofferdam-type plugging to ensure that the breach water flow stagnates. Subsequently, the breach is densely reinforced by filling and compacting embankment materials, and then the anchor-type plugging device is dismantled and recovered. The device can be used to achieve breach sealing or river diversion under any water flow conditions, and has the advantages of low construction cost, high efficiency, safety and reliability.

DETAILED DESCRIPTION

[0016] Embodiment 1, see attached Figure 1-2 , an anchor-cable type flow interception and plugging device, comprising an anchor body 1, a plugging object 2 and a rope 3, wherein a plurality of plugging objects 2 are connected side by side to form an arched plugging body, the arched plugging body maintains a stable shape due to resistance to water flow pressure, and is not prone to the phenomenon of the plugging body being unstable and being washed away by water flow, the arched plugging body is arranged in a multi-layer stacking manner according to the depth of the breach, the arched plugging body is arranged on the inner side of the breach, and is bent toward the upstream of the breach, the two ends of the arched plugging body are respectively connected to the two sides of the breach, and the two end parts of the arched plugging body are embedded in the foundation on both sides of the breach, so as to avoid Water seepage occurs at the joint, and the sides of adjacent sealing objects 2 in the arched sealing body contact each other to form a sealing structure. After the sealing objects 2 are joined, the sealant can be filled in the joint between the two to ensure the sealing effect of the joint; each sealing object 2 is connected to a rope 3, and the adjacent ropes 3 are evenly arranged radially upstream with the breach as the center, and an anchor body 1 is connected to the inner end of the rope 3. This arrangement of the ropes 3 can ensure that each sealing object 2 is evenly stressed, thereby avoiding the phenomenon that the arched sealing body structure is unstable or even deformed and collapsed due to uneven pulling force and superimposed water pressure.

[0017] The rope 3 is a cable or a chain, and is provided with a rope buckle 4 for adjusting its length, so that the rope 3 is in a tensioned state between the anchor body 1 and the blocking object 2, ensuring that the anchor body 1 can pull the blocking object 2 through the rope 3.

[0018] The anchor 1 is a metal anchor, which is sunk into the mud and sand at the bottom of the water body or anchored on the embankments on both sides to achieve anchoring; or the anchor 1 is set as a sandbag filled with mud and sand or a gabion filled with stone, and anchoring is achieved by the deadweight of the sandbag or gabion. The plugging object 2 is a gabion or geotextile filled with stone, which sinks to the bottom of the water at the breach interception point by its own gravity; or the plugging object 2 is set as a prefabricated concrete component, which is an integral component matching the breach size, or a plurality of small components connected to each other by a mechanical docking mechanism.

[0019] When the anchor-cable type flow interception and plugging device is used to plug a breach, the plugging device is transported to the upstream of the breach by a ship, one end of the rope 3 is connected to the anchor body 1, and the anchor body 1 is thrown at multiple points at a distance from the breach. The anchor body 1 has a large gravity and sinks directly to the ground after being thrown. The anchor body 1 is radiated in an arc with the breach as the center. The other end of each rope 3 is left on the ship and connected to the plugging object 2. The distance from the anchor body 1 to the breach is the length of the rope 3, and then the ship moves to the upper part of the breach. The sealing object 2 is thrown at a close swimming distance. When the water body is deep, the sealing object 2 is stacked in multiple layers to avoid entanglement of the ropes 3 between the devices when throwing. The sealing object 2 relies on the drag force of the water flow to realize its own movement toward the breach in the water body, and the drag force of the water flow can be increased by additionally binding floating objects to the sealing object 2. When the sealing object 2 moves to the breach, the rope 3 is straightened, and the anchor body 1 provides tension to resist the drag force of the water flow on the sealing object 2, so that the sealing object 2 cannot continue to move downstream of the breach, thereby achieving sealing.

[0020] Embodiment 2, see attached Figure 3 This embodiment includes the anchor-rope type flow interception and plugging device in the first embodiment. When the anchor-rope type flow interception and plugging device is used to plug the breach, multiple anchor bodies 1 of the device are connected to ropes 3, and the anchor bodies 1 are cast at multiple points on the bank near the breach. When the anchor body 1 is light, it can be cast at a long distance by a thrower or a drone. The rope 3 should be long enough to avoid the casting deviation causing the distance between the anchor body 1 and the breach to be greater than the length of the rope 3. The casting position presents a radial distribution with the breach as the center on the plane, and then the connected rope 3 is directly cast at the breach. The rope 3 and the floating plugging material 2 are dumped one by one, and the entanglement of the rope 3 between the devices is avoided during dumping. The dumped plugging material 2 forms a transportation channel, and the plugging material 2 can be spread in multiple levels to facilitate the forward transportation of the subsequent plugging material 2 during the plugging process; when the anchor body 1 is heavier, the anchor body 1 also needs to be laid from the shore to the water area. When the water flow at the anchor body 1 is weak, other sand and gravel materials can be mixed when filling the anchor body 1. The anchor body 1 and the plugging material 2 form a double-layered embankment, and finally the embankment of the plugging material 2 is closed.

[0021] Embodiment 3, see attached Figure 4This embodiment includes the anchor-type intercepting and plugging device in the first embodiment. When the anchor-type intercepting and plugging device is used to intercept the river channel, multiple anchor bodies 1 of the device are fixed on the left and right banks of the upstream, and the anchor bodies 1 are connected with ropes 3 and plugging objects 2. The plugging objects 2 are transported to the upstream of the breach by ships for throwing one by one. Before throwing, the plugging objects 2 need to be connected to the anchor bodies 1 one by one with ropes 3. With the help of the drag force of the water flow, the plugging objects 2 are rushed downstream and stopped at the breach by the traction of the ropes 3. The plugging objects 2 form an arched plane arrangement at the breach. The plugging objects 2 can also be transported by land and thrown and filled at the breach dike. Before throwing and filling, the plugging objects 2 also need to be connected to the anchor bodies 1 one by one with ropes 3.
