Abstract
Description
Technical Field
[0001] This utility model relates to a dam breach sealing device, including water barriers, heavy barriers, anchored barriers, pile-based barriers, and sinking strips. These devices are mainly used to seal floods, especially to seal dam breaches. They are prefabricated components that are easy to mass-produce and belong to flood control, disaster relief and rescue materials, as well as flood control preparedness equipment. Background Technology
[0002] Existing technological theories for sealing breaches mainly include: earth and rock sealing, truck-delivered stone sealing, steel and wood combination sealing, and mechanized sealing.
[0003] Earth and rock sealing: This is the safest method of sealing the breach, with almost no risk, but it requires a calm water flow. Although direct earth and rock sealing results in greater losses, it offers high safety.
[0004] Trucks transporting stones for roadblocks: This method carries the highest risk and cost, and the timing for drivers to jump out of the truck is difficult to determine; it is suitable for emergency situations.
[0005] Steel-wood composite sealing: This method is used when mechanized operations are not feasible. Steel pipes are fixed along the original embankment line to form a frame, and then filled with soil and rocks to form a composite water-retaining structure.
[0006] Mechanized blocking: High efficiency, but requires high site and traffic conditions. It uses mechanical equipment such as dump trucks and bulldozers for mechanized joint operations.
[0007] Clearly, the aforementioned existing methods for sealing breaches are all temporary emergency measures. Currently, no research or theory has proposed a method for sealing breaches by prefabricating and stockpiling flood sealing equipment suitable for large-scale production. Summary of the Invention
[0008] The purpose of this utility model is to propose a technical solution that leverages industrial advantages to mass-produce prefabricated components for sealing dike breaches, enabling the rapid sealing of breaches by replacing stones with prefabricated components. The technical solution of this utility model includes: a water barrier, which is a hollow triangular pyramid welded from steel bars, with at least one spike formed by an extension of a steel bar at each corner; a heavy-duty barrier, which is a hollow triangular pyramid welded from angle iron, square steel, or steel pipe; an anchoring barrier constructed using the aforementioned heavy-duty barrier, which consists of the heavy-duty barrier, rigging, and an anchor, with the heavy-duty barrier connected to the anchor via the rigging; and a pile-foundation barrier constructed using the aforementioned heavy-duty barrier, which consists of ground piles, rigging, and the heavy-duty barrier, connected in series by the rigging, with ground piles poured into the dikes at both ends of the breach, and the ends of the rigging connected to the ground piles. A type of sinking strip, which consists of sinking stones, woven strips, and cable ties. The woven strips are folded in half, the sinking stones are wrapped around the folds, and then tied tightly with cable ties. Attached Figure Description

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0037] Comparison Appendix Figure 1 , Figure 1 This is a three-dimensional diagram of a water-resistant barrier, one of the devices described in this utility model. A water-resistant barrier is a barrier that can stand upright in floodwaters, allowing the flood to pass through without being swept away. (Compare with...) Figure 1It can be seen that the water barrier 1 in the diagram includes at least three different structural styles: ①, ②, and ③. ① is a hollow triangular pyramid made of welded steel bars; ② is a triangular pyramid made of three angle irons intersecting at 90-degree angles and welded together; and ③ is a hollow triangular prism made of welded steel bars. (Compare) Figure 1 It can be seen that because all three types of water barriers are hollow or suspended structures, they are less affected by the impact of floods, making them easier to stand in the water and less likely to be washed away. (Comparison) Figure 1 It can also be seen that, in order to keep the water barrier 1 fixed in the water and prevent it from being washed away, the first and third types of water barriers, which are made of welded steel bars, have at least one long steel bar at each corner, forming an extended side, and the end of the steel bar is ground into a spike; the second type is a triangular pyramid made of angle iron, and both ends of each angle iron are cut into spikes; the spikes on the water barriers of the above three different structural styles are collectively referred to as cone spikes. When the water barrier is impacted by flood and rolls or moves, the cone spikes will easily insert into the mud, thereby fixing the water barrier in the turbulent water flow.
[0038] Comparison Appendix Figure 2 , Figure 2 This is a schematic diagram illustrating the usage of the water barrier, one of the devices in this utility model. From... Figure 2 As can be seen, when a flood breaches a levee, a large number of water-resistant barriers 1 are thrown into the breach area 2, causing them to spread and stack flat. Because the water-resistant barriers 1 are hollow triangular pyramids with long spikes at each corner, the numerous water-resistant barriers 1 easily intersect and interlock under the impact of the water flow, forming a stable whole. On the one hand, this stable whole also has a hollow structure, allowing the floodwater to pass through normally, thus experiencing relatively little impact from the flood; on the other hand, the spikes of the numerous water-resistant barriers 1 are embedded in the soil, creating a strong grip that is extremely difficult to move. This whole, composed of numerous water-resistant barriers interlocking and overlapping, forms a skeleton mixed within the floodwaters. We call this skeleton formed by the interlocking and stacking of numerous water-resistant barriers 1 in the floodwaters the "framework 3".
[0039] Obviously, when attached Figure 2 Once the sturdy support frame 3 shown is formed, the goal of blocking the flood has been largely achieved. At this point, we only need to fill the support frame 3 with stones or other sealing materials to easily intercept the flood and seal the breach.
[0040] Of course, the above applies to situations where the flood flow velocity is not high. If the flood flow velocity and volume are relatively high, and the impact force of the flood is strong, in order to prevent accidents during the sealing process, we can further insert a large number of steel bars into the inside of the support frame 3. The steel bars will further connect the various water barriers 1, making their interconnection more secure and further stabilizing the support frame 3. After completing this step, the sealing can then be carried out.
[0041] Furthermore, in comparison with the appendix Figure 3 , Figure 3 This is a schematic diagram of the appearance of the second type of material in this utility model, the sinking strip. The sinking strip 4 consists of sinking stones 4.1, woven strips 4.2, and cable ties 4.3. The woven strip 4.2 is folded in half, and the sinking stone 4.1 is wrapped around the fold, then secured with the cable ties 4.3. Clearly, this sinking strip 4 is a very low-cost and convenient material. Its purpose is to replace the large quantity and weight of stones with this lightweight and small material, thereby significantly reducing workload and improving sealing efficiency. The sinking stones 4.1 can be small stones or bricks. The length of the folded woven strip 4.2 needs to be greater than the height of the water barrier 1, and preferably greater than the depth of the flood, and also has a certain width. This design of the sinking strip 4 makes it small in size, lightweight, and highly effective, making it very suitable for large-scale deployment at once. When a large number of slabs 4 are placed in front of or inside the support frame 3, the slabs 4.1 sink to the bottom, while the woven strips 4.2 float upwards and are pierced by the spikes of the water barrier 1 under the impact of the water flow, thus suspending and wrapping around the water barrier 1. When a large number of woven strips 4.2 overlap and hang and wrap around the water barrier 1 layer by layer, the water barrier 1 has the ability to prevent the flood from passing through. The water barrier 1 wrapped by a large number of woven strips 4.2 will turn the entire support frame 3 into a woven mesh wall that can block the flow of floodwater, thereby cutting off the flood and completing the sealing of the breach 2.
[0042] Furthermore, the above-mentioned method of using only water-blocking barriers 1 and sinking strips 4 to seal the breach has the following drawbacks: First, the demand for sinking strips 4 is very large, and the efficiency is relatively low; second, if a large number of woven strips 4.2 are placed inside the support frame 3, that is, at the breach location, it will bring new difficulties and problems to the subsequent cleaning and repair of the breach.
[0043] Comparison Appendix Figure 4 , Figure 4 This is a schematic diagram illustrating the usage of the second component of this utility model, the settling and plugging strip. (See diagram for example.) Figure 4As shown, before using the blocking strip 4, we need to lay a barrier net 5 in front of the support frame 3. Obviously, since the barrier net 5 is also a water-passing body, it has relatively low resistance in the water. After the support frame 3 is formed, we can easily lay a barrier net 5 in front of it. This barrier net 5 can be wire mesh or rope netting; it is a very simple and readily available material that is easy to mass-produce. Moreover, there are many alternative materials available, such as wire mesh fences, partition nets, steel mesh panels, stainless steel mesh, wire mesh bed boards, etc. Therefore, no special customization is required; direct purchase is sufficient. (Refer to Appendix) Figure 4 It can be seen that in front of the net wall formed by the barrier net 5 is the "area for placing the blocking strips". In this area, the blocking strips 4 are placed. The woven strips 4.2 will stick tightly to the barrier net 5 under the impact of the water flow. When a large number of blocking strips 4 are placed, a large number of woven strips 4.2 can form a woven net wall in front of the barrier net 5 to block the flood, thereby blocking the flood and completing the sealing of the breach 2.
[0044] Theoretically, due to the special structure of the water barrier 1, the support frame 3 has good water passage and low resistance in floods. Furthermore, the numerous spikes on the water barrier 1 are embedded in the soil, forming a unified whole with extremely strong grip. Therefore, the formation and stability of the support frame 3 in floods is not a problem. However, when the woven mesh wall is used to block the flood flow, if the flood volume is large and the flow velocity is fast, the powerful water pressure creating a huge thrust on the support frame 3 is still very dangerous. Therefore, we believe that the above technical solution is more suitable for breaches with relatively slow water flow and weak impact. For breaches with high flow velocity and strong impact, further improvements to the technical solution are needed.
[0045] Comparison Appendix Figure 5 , Figure 5 This is a three-dimensional view of the triple-layered chevaux-de-frise, a component of this utility model. (Compare with...) Figure 5 It can be seen that at least three different structural designs of the heavy-duty barricade 6 are proposed here, namely ①, ②, and ③. The first type of heavy-duty barricade 6 has the same structure as the first type of water barricade 1. It is a hollow triangular pyramid made of angle iron instead of steel bars and welded together. Since the structural strength of angle iron is better than that of steel bars and it is not easy to bend and deform, it has better strength and support. Similarly, each corner of the triangular pyramid has at least one spike formed by the extended side. Figure 5 The second type of heavy-duty chevaux-de-frise, the 6th type, is a hollow triangular cone made of welded steel pipes, which may or may not have spikes. The third type of heavy-duty chevaux-de-frise, the 6th type, is a hollow triangular prism made of welded steel pipes, with spikes at its base. The main characteristics of these three types of heavy-duty chevaux-de-frise are their larger size and higher structural strength, making them suitable for floods with large flow rates, high velocities, and greater ferocity.
[0046] The above-mentioned water-resistant barriers 1 and heavy-duty barriers 6 can be selected and used reasonably according to the intensity of the flood and the method of use, or they can be used in combination.
[0047] Comparison Appendix Figure 6 , Figure 6 This is a perspective view of the fourth type of equipment of this utility model: the anchoring baluster. The anchoring baluster 7 consists of a heavy-duty baluster 6, a rigging 8, and an anchor 9. The heavy-duty baluster 6 is connected to the anchor 9 via the rigging 8. (Comparison) Figure 6 It can also be seen that the anchored barricade 7 was selected Figure 5 The first type of heavy-duty chevaux-de-frise is a heavy-duty chevaux-de-frise 6 made of welded angle iron and equipped with spikes. Therefore, this anchoring chevaux-de-frise 7 provides both the traction fixation of the anchor 9 and the fixation of the spikes penetrating deep into the soil, thus achieving a dual fixing effect. Of course, the heavy-duty chevaux-de-frise 6 here can also be made of... Figure 5 The second type is a heavy-duty chevaux-de-frise made of welded steel pipes, or the third type is a hollow triangular prism heavy-duty chevaux-de-frise made of welded steel pipes.
[0048] Comparison Appendix Figure 7 , Figure 7 This is a schematic diagram illustrating the usage of the fourth type of anchoring barrier in this utility model. (See diagram for reference.) Figure 7 As can be seen, when facing more ferocious floods, we can first place anchors 9 upstream of the breach. Using the anchors 9 for anchoring, and with the traction of rigging 8, we can deploy heavy balusters 6 downstream of the breach. By placing multiple anchored balusters 7 in this way, we can form a heavy baluster 6 anchored by anchors 9 downstream of the breach. Clearly, these heavy balusters 6 have a more stable structure and can remain stable in the raging floodwaters. Based on this, by placing more heavy balusters 6 or a large number of water balusters 1 in front of these anchored balusters 7, we can form an even more stable support structure 3, capable of dealing with even more turbulent floods.
[0049] Furthermore, in comparison with the appendix Figure 8 , Figure 8 This is a three-dimensional view of the fifth type of bollard of this utility model. (Compare with...) Figure 8 It can be seen that the pile foundation baluster 10 consists of heavy baluster 6, rigging 8, and ground piles 11. The heavy baluster 6, with a total length matching the width requirement of the breach 2, is connected by rigging 8. Ground piles 11 are poured into the embankment at both ends of the breach 2. Through the traction of the ground piles 11, the heavy baluster 6 is fixed downstream of the breach 2, thus forming a more robust support base. Figure 8 As can be seen from the data, the pile foundation baluster 10 is made of steel pipe welded together and is a heavy baluster 6 without spikes. This is because the ground pile 11 itself has a very solid positioning, so there is no need for the heavy baluster 6 to be fixed itself. The heavy baluster 6 mainly plays a strong supporting role. The absence of spikes makes it easy to move and transport, and the heavy baluster 6 can be deployed and positioned more conveniently.
[0050] Comparison Appendix Figure 9 , Figure 9 This is a schematic diagram illustrating the usage of the fifth type of bollard, a component of this utility model. From... Figure 9 As can be seen, when encountering exceptionally fierce floods, we can first pour a pile 11 into each of the two sides of the breach, and then connect heavy-duty balusters 6 with a total length matching the width requirement of the breach 2 using rigging 8. This pile-based balusters 10 will then establish the first stable support base downstream of the breach. Further, comparing... Figure 9 Then, we install anchoring barriers 7 in front of the first support base to form the second support base. Further, in front of the second support base formed by the anchoring barriers 7, at the breach point, we deploy a large number of water barriers 1 to form the third support base. At this point, the support frame 3, formed by the combination of the first, second, and third support bases, will be able to remain immovable even in high-speed, high-flow floods. Then, we install a barrier net 5 in front of the third support base, and deploy a large number of sinking blocks 4 in front of the barrier net 5 to intercept any raging floodwaters.
[0051] Clearly, the work of sealing the breach 2 was not over after the flood was blocked by the sinking strip 4; on the contrary, the real sealing of the breach had just begun.
[0052] Comparison Figure 4 , Figure 9 The reason we placed the water barrier 1 in the center directly opposite the breach 2 and the sinking bar 4 upstream of the breach 2 is that once the flood is blocked by the sinking bar 4, the entire breach 2 will be completely exposed. Since the water barrier 1 is made of steel bars, we only need to add a certain number of steel bars at the location where the water barrier 1 is piled up, depending on the strength and structural requirements. Then we can directly pour cement into the location where the water barrier 1 is piled up, using the water barrier 1 directly as a cement skeleton to quickly complete the permanent repair and reinforcement of the dam. Afterwards, the sinking bar 4, the barrier net 5, and the heavy barrier 6 will be cleared, and the entire breach sealing work will be completed.
[0053] Clearly, the above-mentioned technical solution requires very little stone in sealing breaches (only a small amount of stone is involved in the sealing strips). By prefabricating a large number of water barriers, sealing strips, and other prefabricated components in advance to replace the temporary transportation of stones, the workload at the sealing site is greatly reduced, and the work efficiency is improved. It is of great significance for quickly stopping floods and saving people's lives and property, and deserves to be widely popularized and promoted.
[0054] Comparison Appendix Figure 10 , Figure 10This is a schematic diagram of the ground pile construction for the equipment of this utility model. The state attaches great importance to flood control, and all regions have special funds for flood control work every year. Therefore, it is recommended that, under the guidance of the above-mentioned flood blocking methods, a portion of the funds in daily flood prevention measures could be allocated to the key monitored dikes 12 to construct ground piles 11 as shown in the figure in advance. Obviously, these ground piles 11 can not only reinforce the dikes 12, but also prepare for a rainy day. If a dike breach occurs, these ground piles 11 can be directly used to deploy pile-based chevaux-de-frise 10 to achieve the purpose of quickly sealing the breach.
