Description

Technical Field

[0001] The invention relates to a method for plugging a breach, which refers to a method for using industrial production capacity to mass-produce flood control equipment such as water chevaux de frise, sinking blocking strips, anchored chevaux de frise, heavy chevaux de frise and the like, and using light and sturdy flood control equipment to replace heavy stones that are very time-consuming, labor-intensive and inefficient to load, transport and place to plug floods. Background Art

[0009] In the existing technical theories, the methods used to seal the breach mainly include: earth and stone sealing, truck-transported stone sealing, steel and wood combination sealing, mechanized sealing, etc.

[0010] Earth and rock plugging: This is the safest plugging method with almost no risk, but it requires the water flow to be gentle. Directly plugging with earth and rock will cause greater losses but is highly safe.

[0011] Trucks transporting stones to block the blockage: This has the greatest risk and is costly, and requires the driver to jump out of the vehicle at a time that is difficult to grasp. It is only suitable for emergency situations.

[0012] Steel-wood combined sealing: It is used when mechanized operation conditions are not available. Steel pipes are fixed into a frame along the original embankment line, and then filled with soil and rocks to form a composite water retaining structure.

[0013] Mechanized blocking: high efficiency, but high requirements on site and traffic, using dump trucks, bulldozers and other mechanical equipment for mechanized joint operations.

[0014] Obviously, the above existing methods for sealing the breach are temporary emergency methods. At present, there is no research theory that proposes a method for sealing the breach by prefabricating and storing flood sealing equipment suitable for large-scale production. Summary of the invention

[0015] The purpose of the present invention is to invent a method of using the advantages of industrialization to mass-produce prefabricated equipment that can be used for plugging breaches, so that prefabricated parts can be used to replace stones when floods break the dam, and a method of quickly plugging the breach is implemented. The technical solution of the present invention: a method for plugging a breach, characterized by: making water dams and sinking strips; when a flood occurs, throwing water dams to the breach, so that the water dams are laid flat and stacked in the breach area to form a grinding frame, throwing sinking strips in front of the grinding frame, and using the pressure of the flood to attach the braided strips on the sinking strips to the grinding frame to form a braided mesh wall to block the flood. The water dam is a hollow triangular cone welded with steel bars. The sinking strip is composed of sinking stones, braided strips, and cable ties. The braided strips are folded in half, the sinking stones are wrapped at the fold, and tightened with cable ties.

[0016] Furthermore, the method further comprises: placing a blocking net in front of the grinding frame, and then placing a sinking strip in front of the blocking net.

[0017] Furthermore, the method also includes: making heavy-duty chevaux de frise, which is a hollow triangular cone welded from angle iron, square steel or steel pipe.

[0018] Furthermore, the method also includes: using heavy-duty chevaux de frise to make anchored chevaux de frise, the anchored chevaux de frise is composed of heavy-duty chevaux de frise, rigging, and anchor, and the heavy-duty chevaux de frise is connected to the anchor through the rigging; when a flood occurs, firstly placing an anchor upstream of the breach, and through the fixing effect of the anchor, under the traction of the rigging, deploying the heavy-duty chevaux de frise to the downstream of the breach, forming a heavy-duty chevaux de frise defense line fixed by the anchor downstream of the breach, and then placing water chevaux de frise in front of the heavy-duty chevaux de frise, forming a scaffolding composed of the anchored chevaux de frise and the water chevaux de frise.

[0019] Furthermore, the method also includes: connecting heavy-duty chevaux de frise in series through rigging, and pouring ground piles on the embankments at both ends of the breach, fixing the heavy-duty chevaux de frise downstream of the breach through the traction of the ground piles, and then placing water chevaux de frise in front of the heavy-duty chevaux de frise to form a scaffolding composed of pile-based chevaux de frise and water chevaux de frise.

[0020] Furthermore, the method further comprises: inserting steel bars into the grinding frame and connecting the water barriers with the steel bars. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Compare with Figure 1, Figure 1 This is a three-dimensional diagram of a water barrier, one of the blocking devices of the method of the present invention. A water barrier is a barrier that can stand in a flood, allowing the flood to pass through without being washed away by the flood. Figure 1 It can be seen that the water barrier 1 in the figure includes at least three different structural styles: ①, ②, and ③. Among them, ① is a hollow triangular pyramid welded by steel bars; ② is a triangular pyramid welded by three angle irons crossed at 90 degrees; ③ is a hollow triangular prism welded by steel bars. Figure 1 It can be seen that since the three types of water barriers are all hollow or overhead structures, they are less impacted by floods and are easy to stay in the water and not easily washed away. Figure 1 It can also be seen that in order to fix the water dam 1 in the water and not be washed away, at least one longer steel bar is used at each corner of the two types of water dams welded by steel bars, forming an extended edge, and the ends of the steel bars are polished into spikes; the second type is a triangular pyramid welded by angle irons, and both ends of each angle iron are cut into spikes; the spikes on the three different structural styles of water dams 1, ①, ②, and ③, are collectively referred to as cone spikes. When the water dam 1 is rolled or moved by the impact of floods, the cone spikes can easily be inserted into the soil, thereby fixing the water dam in the turbulent water flow.

[0050] Compare with Figure 2 , Figure 2 This is a schematic diagram of the use of a water barrier, one of the plugging equipment in the method of the present invention. Figure 2 It can be seen from the figure that when the flood breaks the dike, a large number of water dams 1 are thrown to the breach mouth 2, so that the water dams 1 are laid flat and stacked in the breach mouth area. Since the water dams 1 are hollow triangular pyramids, and each corner has long cone thorns, this makes it easy for a large number of water dams 1 laid flat and stacked together to cross each other, and tightly staggered and interlaced under the impact of the water flow to form a stable whole. On the one hand, this stable whole also has a hollow structure, and the flood can pass normally, so the impact force of the flood is relatively small; on the other hand, the cone thorns of a large number of water dams 1 are inserted into the soil, forming a grip that is extremely difficult to move. This whole composed of a large number of water dams interlaced and interlaced constitutes a skeleton mixed in the flood. We call this skeleton formed in the flood by a large number of water dams 1 interlaced and stacked as a whet frame 3.

[0051] Obviously, when the Figure 2 When shown in the stable rubbing frame 3 is formed, the target of blocking flood has just been realized more than half. At this moment, we only need to fill stones or other blocking materials inside the rubbing frame 3, just can relatively easily cut off the flood, block the breach.

[0052] Of course, the above situation is applicable to the case where the flood flow rate is not large. If the flow rate and flow rate of the flood are relatively large, and the impact of the flood is relatively strong, in order to prevent accidents during blocking, we can further insert a large number of steel bars into the inside of the frame 3, and further connect the water barriers 1 through the steel bars to make them more firmly connected to each other, which plays a role in further stabilizing the frame 3. After completing this step, the blocking can be implemented.

[0053] Furthermore, referring to the attached Figure 3 , Figure 3 It is a schematic diagram of the appearance of the second blocking strip of the blocking equipment of the method of the present invention. The blocking strip 4 is composed of a sinking stone 4.1, a braided strip 4.2, and a cable tie 4.3. The braided strip 4.2 is folded in half, the sinking stone 4.1 is wrapped at the folded part, and is tightened with a cable tie 4.3. Obviously, the sinking strip 4 is a convenient equipment with extremely low cost. The purpose of the equipment is to replace the stones with extremely large demand and extremely heavy weight with this light weight and small volume equipment, thereby greatly reducing the workload and improving the blocking efficiency. The sinking stone 4.1 can be made of smaller stones or bricks. The length of the braided strip 4.2 after folding in half needs to be greater than the height of the water barrier 1, and preferably greater than the depth of the flood, and has a certain width. The sinking strip 4 designed in this way is small in size, light in weight, and has a large effect, which is very suitable for one-time large-scale delivery. When a large number of sinking strips 4 are placed in front of or inside the grinding frame 3, the sinking stones 4.1 sink to the bottom of the water, while the braided strips 4.2 float upward, and are pierced by the cones of the water barrier 1 under the impact of the water flow, and are hung and wrapped on the water barrier 1. When a large number of braided strips 4.2 are alternately overlapped, hung and wrapped on the water barrier 1 layer by layer, the water barrier 1 has the ability to prevent the flood from passing through, and a large number of water barriers 1 wrapped by the braided strips 4.2 will turn the entire grinding frame 3 into a braided mesh wall that can block the flood from flowing through, thereby cutting off the flood and completing the blocking of the breach 2.

[0054] Furthermore, the above method has defects: first, the demand for the blocking strips 4 will be very large, and the efficiency is relatively low; second, if a large number of woven strips 4.2 are placed inside the frame 3, that is, at the breach position, it will bring new difficulties and problems to the subsequent cleaning and repair of the breach.

[0055] Compare with Figure 4 , Figure 4 This is a schematic diagram of the use of the second plugging device of the present invention, the sinking strip. Figure 4As shown, before using the sinking strip 4, we need to lay a barrier net 5 in front of the grinding frame 3. Obviously, since the barrier net 5 is also a water body and has less resistance in the water, after the grinding frame 3 is formed, we can easily lay a barrier net 5 in front of the grinding frame 3. The barrier net 5 can be a wire mesh or a rope net. It is also a very simple and easy to prepare in large quantities. There are also many alternatives, such as wire mesh fences, partition nets, steel mesh sheets, stainless steel mesh, wire mesh bed boards, etc. Therefore, there is no need for special customization and direct purchase is sufficient. Figure 4 It can be seen that in front of the net wall formed by the barrier net 5 is the "sinking strip placement area". Sinking strips 4 are placed in this area, and the braided strips 4.2 will be tightly attached to the barrier net 5 under the impact of the water flow. When a large number of sinking strips 4 are placed, a large number of braided strips 4.2 can form a braided net wall in front of the barrier net 5 to block the flood, thereby blocking the flood and completing the blocking of the breach 2.

[0056] From a theoretical analysis, since the water barrier 1 has a special structure, the grinding frame 3 has good water-passing performance and less resistance in the flood. At the same time, a large number of cones on the water barrier 1 are inserted into the soil and form a whole, which has an extremely stable grip. Therefore, there is no problem in the formation and stability of the grinding frame 3 in the flood. However, when the woven fabric mesh wall is to cut off the flood, if the flood flow is large and the flow rate is fast, the huge thrust formed by the strong water pressure on the grinding frame 3 is still very dangerous. Therefore, we believe that the above technical solution is more suitable for the breach with slow water flow and weak impact. For the breach with large flow rate and strong impact, the technical solution needs to be further improved.

[0057] Compare with Figure 5 , Figure 5 This is a three-dimensional diagram of the triple-layer chevaux de frise of the blocking device of the method of the present invention. Figure 5 It can be seen that at least three different structural styles of heavy-duty chevaux de frise 6 are proposed here. The first heavy-duty chevaux de frise 6 has the same structure as the first water chevaux de frise 1, which is a hollow triangular cone welded with angle irons instead of steel bars. Since the structural strength of angle irons is better than that of steel bars, they are not easy to bend and deform, and thus have better strength and support. Similarly, each corner of the triangular cone has at least one cone thorn formed by an extended edge. Figure 5 The second type of heavy-duty chevaux de frise 6 is a hollow triangular cone welded from steel pipes, which may or may not be designed with spikes. The third type of heavy-duty chevaux de frise 6 is a hollow triangular prism welded from steel pipes, with spikes designed at the bottom. The main features of these three types of heavy-duty chevaux de frise 6 are larger size and higher structural strength, which are suitable for floods with large flow, fast flow rate and more ferocious floods.

[0058] The above-mentioned water chevaux de frise 1 and heavy chevaux de frise 6 can be reasonably selected and used according to the intensity of the flood and the mode of use, and can also be used in combination.

[0059] Compare with Figure 6 , Figure 6 This is a three-dimensional diagram of the fourth anchored chevaux de frise of the blocking device of the method of the present invention. The anchored chevaux de frise 7 is composed of a heavy chevaux de frise 6, a rigging 8, and an anchor 9. The heavy chevaux de frise 6 is connected to the anchor 9 through the rigging 8. Figure 6 It can also be seen that the anchor barricade 7 has chosen Figure 5 The first type of heavy-duty chevaux de frise is a heavy-duty chevaux de frise 6 welded with angle iron and provided with a cone thorn. Therefore, the anchoring chevaux de frise 7 has both the traction fixation of the anchor 9 and the fixation of the cone thorn deep into the soil, which can play a dual fixing role. Of course, the heavy-duty chevaux de frise 6 here can also be completely adopted Figure 5 The second type is a heavy-duty chevaux de frise 6 welded with steel pipes, or the third type is a hollow triangular prism-type heavy-duty chevaux de frise 6 welded with steel pipes.

[0060] Compare with Figure 7 , Figure 7 This is a schematic diagram of the method for using the fourth anchor barricade, one of the blocking devices of the method of the present invention. Figure 7 It can be seen that in the face of more fierce floods, we can first place anchors 9 upstream of the breach, and through the fixing effect of anchors 9, under the traction of rigging 8, heavy-duty chevaux 6 can be deployed to the downstream of the breach. By placing multiple anchored chevaux 7 in this way, we can form a heavy-duty chevaux 6 fixed by anchors 9 downstream of the breach, and it is obvious that these heavy-duty chevaux 6 have a more stable structure and can stabilize in the turbulent flood. On this basis, we place more heavy-duty chevaux 6 or a large amount of water chevaux 1 in front of these anchored chevaux 7, and a more stable frame 3 can be formed to cope with more turbulent floods.

[0061] Furthermore, referring to the attached Figure 8 , Figure 8 This is a three-dimensional diagram of the five-pile foundation barricades used as the blocking equipment in the method of the present invention. Figure 8 It can be seen that the pile foundation barrier 10 is composed of heavy barrier 6, rigging 8, and ground piles 11. The heavy barrier 6 with a total length that meets the width requirement of the breach opening 2 is connected in series through the rigging 8, and the ground piles 11 are poured on the embankment at both ends of the breach opening 2. The heavy barrier 6 is fixed downstream of the breach opening 2 through the traction of the ground piles 11, thereby forming a more solid supporting base. Figure 8It can be seen that the pile foundation chevaux de frise 10 has chosen the heavy-duty chevaux de frise 6 which is welded with steel pipes and has no spikes. This is because the pile 11 itself has a very firm positioning, and therefore the heavy-duty chevaux de frise 6 no longer needs to be fixed by itself. The heavy-duty chevaux de frise 6 mainly plays a strong supporting role, and the absence of spikes makes it easier to move and carry, and the heavy-duty chevaux de frise 6 can be deployed and positioned more conveniently.

[0062] Compare with Fig. 9 , Fig. 9 It is a schematic diagram of the use of the five pile foundation barriers of the blocking equipment of the method of the present invention. Fig. 9 It can be seen from the figure that when encountering an extremely fierce flood, we can first pour a ground pile 11 on each side of the embankment at the breach, and then connect the heavy-duty chevaux de frise 6 with a total length that meets the width requirements of the breach 2 through the rigging 8, and use the pile foundation chevaux de frise 10 to establish the first stable support base downstream of the breach. Then, further, compare Fig. 9 , we then set anchoring chevaux de frise 7 in front of the first support base to form a second support base. On this basis, further, in front of the second support base formed by the anchoring chevaux de frise 7, that is, at the breach position, a large number of water chevaux de frise 1 are placed to form a third support base. From then on, the scaffolding frame 3 formed by the combination of the first support base, the second support base, and the third support base will have the ability to remain motionless in high-speed, high-flow floods. At this point, we then set a blocking net 5 in front of the third support base, and then place a large number of sinking bars 4 in front of the blocking net 5, which can cut off any fierce flood.

[0063] Obviously, after the flood is blocked by the blocking strip 4, the blocking work of the breach 2 is not over. On the contrary, the real blocking of the breach has just begun.

[0064] Comparison Figure 4 , Fig. 9 The reason why we set the water dam 1 in the central position opposite to the breach opening 2 and the blocking strip 4 in the upstream position of the breach opening 2 is that when the flood is blocked by the blocking strip 4, the entire breach opening 2 will be completely exposed. Since the water dam 1 is made of steel bars, at this time, we only need to further add a certain number of steel bars at the position where the water dam 1 is stacked depending on the strength and structural requirements, and then we can directly pour cement on the stacking position of the water dam 1, and use the water dam 1 directly as a cement skeleton to quickly complete the permanent repair and reinforcement of the dam. Subsequently, the blocking strip 4, the barrier net 5, and the heavy-duty dam 6 will be cleaned, and the entire breach opening blocking work will be completed.

[0065] Obviously, the above technical solution makes the demand for stones in the breach blocking extremely small (only a small amount of stones are involved in the blocking strips). By making a large number of prefabricated parts such as water barriers and blocking strips in advance to replace the temporary transportation of stones, the workload at the blocking site is greatly reduced and the work efficiency is improved. It is of great significance to quickly prevent floods and save people’s lives and property losses, and it deserves to be popularized and promoted.

[0066] Compare with Fig.10 , Fig.10 The state attaches great importance to flood prevention work, and each region has special funds for flood prevention work every year. Therefore, it is recommended that under the guidance of the above-mentioned flood blocking method, a part of the funds can be allocated to the key monitored embankments 12 in daily flood prevention measures, and construction can be carried out in advance. Fig.10 The ground piles 11 shown can not only play the role of reinforcing the embankment 12, but also be prepared for a rainy day. If a dam breach occurs, these ground piles 11 can be directly used to deploy pile foundation barriers 10 to achieve the purpose of quickly blocking the dam breach.

[0067] At the same time, the method of the present invention further provides more specific quantitative indicators for flood control work, such as how many sealing equipment have been prefabricated, whether a plan for loading and transporting the sealing equipment has been formulated, whether the embankment is pre-set with ground piles, etc., which can be used to concretize, quantify and index the flood control work content, thereby making the use of flood control funds and the inspection of flood control work have precise implementation content, assessment indicators and evaluation system.
