Description

Technical Field

[0001] The invention relates to the technical field related to water conservancy project plugging, and in particular to a water-filled net bag type plugging device and a plugging method thereof. Background Art

[0002] The main existing technologies for blocking and repairing dam openings include the traditional Yellow River dredging, earthbag or geotextile packing, stone filling, wire mesh gabion, earthbag cage filling and tetrahedron filling. In urban flood control, once encountering heavy rainfall, the ground convergence is fast and the road water is fierce, it is often necessary to block the subway entrance, underpass tunnel entrance and intersection. Only flood control sandbags can be used to avoid flooding and block the entrance. However, the implementation of the above methods is inseparable from a large amount of emergency materials and equipment, especially when the dam is in a flood. During the period of gate repair or heavy rainfall, on the one hand, there is a lot of rain, muddy roads, and blocked roads on the back of the embankment, which brings many difficulties to the supply needed for flood control and rescue; on the other hand, the amount of flood control materials required is large, the variety is wide, and the storage and transportation are difficult. In addition, it is difficult to organize them quickly due to the influence of external environment, flood situation and other factors, which often delays the opportunity and affects the efficiency of embankment gate repair, which can easily cause the gate to expand or floods to enter low-lying places such as subway tunnels, road underpasses or underground shopping malls, endangering people’s lives and property. In addition, the above method is difficult to implement, and it cannot achieve local materials and reuse. It requires more human, material, financial and other resources, and the rescue efficiency and success rate are low. It is also difficult to clean and repair and reinforce in subsequent maintenance. Summary of the invention

[0003] The embodiment of the present invention provides a water-filled mesh bag plugging device and a plugging method thereof, which are used to solve the technical problems that the existing plugging measures require the preparation of a wide variety of materials, a large investment in manpower, material and financial resources, the implementation method is relatively difficult and complicated, it is difficult to use local materials, and the operation technology requirements are high, the plugging efficiency is low, and it is difficult to clean, repair and reinforce in subsequent maintenance.

[0004] An embodiment of the present invention provides a water-filled mesh bag plugging device, comprising two groups of plugs, a wall formed by stacking a number of water-filled water-filled mesh bag assemblies, and a solid bag assembly adapted to each of the water-filled mesh bag assemblies, the wall being arranged between the two groups of plugs through the solid bag assembly, the two groups of plugs being respectively covered on the embankment head ports of the dam breach, each of the water-filled mesh bag assemblies comprising a water-filled bag and a mesh bag rope, the mesh bag rope being in the shape of a net bag and being sleeved on the outer surface of the water-filled bag, exhaust holes and water inlet holes being arranged at both ends, or one end, or the middle portion of the water-filled bag, retaining ropes extending from both ends of the mesh bag rope, a counterweight being sleeved on one end of each retaining rope close to the bag body, the external end of each retaining rope being tethered to the solid bag assembly, the solid bag assembly comprising a fixed pile (a fixed pile or a wooden pile), or a ground anchor, or a towing boat.

[0005] Its working principle and process are as follows:

[0006] The two groups of plugs are respectively covered on the dike head ports of the dike breach, and can wrap the dike heads on both sides of the dike breach or the mouth, that is, wrap the dike breach or the mouth, which can effectively prevent the dike head from being eroded by water flow, causing the breach or the mouth to continue to expand; a number of water-filled mesh bag assemblies are arranged between the two groups of plugs, that is, a sealed and waterproof continuous water bag wall is formed between the two groups of plugs, and each water-filled bag in the wall is fixed by a retaining rope, a mesh bag rope, and a solid bag assembly, wherein a plurality of water-filled bags are fixed between the two groups of plugs by a consistent number of solid bag assemblies, and the structure is simple and reasonable. , the pulling is stable and firm, the implementation method is relatively convenient, the investment of manpower, material and financial resources is reduced, and the problems of difficult material storage and transportation, high technical requirements and low success rate in the existing plugging and restoration methods are avoided. The technical scheme can directly realize the use of local water materials, and the bag body can be easily recycled and reused afterwards. On the other hand, each water-filled bag is provided with a water inlet hole and an exhaust hole, which can fill the water into the water-filled bag through the water inlet hole and discharge the air inside the water-filled bag through the exhaust hole at the same time, which effectively improves the water filling efficiency, that is, speeds up the supply of plugging materials and effectively improves the rate of plugging operations.

[0007] Furthermore, each fixed bag assembly includes two fixed piles, and the two fixed piles are respectively fixed on the banks of the dam, and the outer ends of the retention ropes are tied to the fixed piles.

[0008] Its working principle and process are as follows:

[0009] The bag-fixing components are arranged along the bank of the embankment. In order to facilitate mechanical or manual piling, the bag-fixing components mostly use steel or iron structured piles, and wooden piles and piles of other materials can also be used.

[0010] Furthermore, the length of each of the fixing piles is 1 meter to 2 meters, the diameter of each of the fixing piles is 10 centimeters to 25 centimeters, the grounding end of each of the fixing piles is provided with a cone, the length of the cone is 10 centimeters to 20 centimeters, and a pile-starting hole is penetrated through the end of each of the fixing piles away from the cone, and the diameter of the pile-starting hole is 12 millimeters to 16 millimeters.

[0011] Its working principle and process are as follows:

[0012] The diameter of the fixed pile is 10 cm to 25 cm, and the length is 1 m to 2 m, that is, the diameter of the fixed pile is proportional to the length of the fixed pile. The longer the length of the fixed pile, the larger the diameter of the fixed pile. Among them, the fixed piles with a length of 1 m to 2 m are mainly used for sandy soil and pile driving on shore, and the fixed piles with a length of 1.5 m to 2 m are mainly used for pile driving in clay soil and in water. The diameter of the cone at the tip of the fixed pile is consistent with the diameter of the fixed pile. A pile starting hole is set at 18 cm to 20 cm from the top of the pile. The diameter of the pile starting hole is 12 mm to 16 mm, which is convenient for mechanical or manual pulling out of the fixed pile.

[0013] Furthermore, each of the solid bag assemblies comprises a ground anchor, or a wire gabion, or a towing boat, and each of the ground anchor or the wire gabion is thrown into the water area and touches the bottom, and the outer end of the retaining rope is tied to the ground anchor or the wire gabion, or the towing boat.

[0014] Its working principle and process are as follows:

[0015] The ground anchor can effectively pull the water-filled bags, fix the water-filled bags, and prevent the water-filled bags from being washed away by the rapids. The wire mesh gabions and towing boats have the same function as the ground anchors and are suitable for laying and pulling water-filled bags at different distances from the port.

[0016] Furthermore, the diameter of the water-filled bag is 0.3 meters to 3.0 meters, the length of the water-filled bag is 3 meters to 20 meters, the diameter of the water inlet hole is 2 inches to 8 inches, the diameter of the exhaust hole is 2 inches to 8 inches, and the water inlet hole and the exhaust hole are both proportional to the volume of the bag body.

[0017] Its working principle and process are as follows:

[0018] Water-filled bags with a diameter of 0.3m to 0.8m and a length of 10m to 20m are used for blocking water flow in urban flood control, repairing flood-control sub-dikes at intersections, tunnels, subway entrances, or embankment projects; water-filled bags with a diameter of 0.8m to 2m and a length of 3m to 10m are used for re-blocking embankment entrances; water-filled bags with a diameter of 2m to 3m and a length of 8m to 10m are used for closing embankment entrances; among them, the size of the water inlet and exhaust holes on the water-filled bag is proportional to the size of the water-filled bag, that is, the thicker the diameter of the water-filled bag and the longer the length, the larger the size of the water inlet and exhaust holes.

[0019] Furthermore, the diameter of the net bag rope is 2 cm to 3 cm, the length of the net bag rope is 10 m to 20 m, and the diameter of the retained rope is 3 cm to 5 cm.

[0020] Its working principle and process are as follows:

[0021] A 10-20 meter long net bag rope is tied to the outer surface of the water-filled bag to form a net bag, and a 10-30 meter long retaining rope is tied to both ends of the net bag rope. The other end of the retaining rope is tied to a fixed pile to pull the water-filled bag to prevent it from being washed away by the water flow. The diameter of the net bag rope and the retaining rope is proportional to the water flow rate, that is, the greater the water flow rate at the mouth or breach, the thicker the diameter of the net bag rope and the retaining rope.

[0022] Furthermore, it also includes a water pump for filling the water-filled bag with water, and the water outlet of the water pump matches the size of the water inlet hole of the water-filled bag.

[0023] Its working principle and process are as follows:

[0024] The water pump can timely fill the water bag with water in a short time. The water outlet of the water pump matches the diameter of the water inlet hole of the water bag, which is convenient for connecting the water outlet of the water pump with the water inlet hole to maintain the water filling efficiency.

[0025] Furthermore, the weight of the counterweight block is 1 / 100 to 1 / 1000 of the weight of the water-filled bag after being filled with water.

[0026] Its working principle and process are as follows:

[0027] After the water-filled bag is pushed or thrown into the water, in order to prevent the water-filled bag from having difficulty touching the bottom or drifting with the water flow, counterweights should be added along the ropes at both ends of the water-filled bag. The size of the counterweight should be determined according to the water flow and the volume of the water-filled bag. If the flow rate is high and the volume of the water-filled bag is large, the weight of the counterweight should be increased accordingly. Keep the weight of the counterweight at 1 / 100 to 1 / 1000 of the weight of the water-filled bag after filling with water.

[0028] Furthermore, the counterweight is an iron weight, a sand bag, or a concrete block.

[0029] On the other hand, a plugging method of a water-filled mesh bag plugging device is provided, using the water-filled mesh bag assembly provided above, and the plugging method of the water-filled mesh bag includes:

[0030] Step 1: Prepare the plugging materials before construction: The plugging materials include water-filled bags, net bag ropes, counterweights, retaining ropes, bag-fixing components and water pumps. After the plugging materials are transported to the site of the mouth, the water-filled bags are filled with water through the water pump, and the net bag ropes are wrapped around the water-filled bags. At the same time, the retaining ropes with counterweights are tied to the two ends of the net bag to form a water-filled net bag component, ready for occupation;

[0031] Step 2: Push and throw the prepared water-filled mesh bag assembly into the mouth, and carry out the occupying operation until it is closed and the air is sealed to complete the blocking operation. In which, the remaining rope on each water-filled mesh bag assembly is tied to the pre-fixed solid bag assembly for fixing.

[0032] Specifically, the above steps 1 and 2 can be divided into the following: first, make preparations before plugging, and prepare plugging materials and tools, mainly including water-filled bags, net bag ropes, counterweights, retaining ropes, bag-fixing components (the bag-fixing components can be made of piles or wooden piles or ground anchors or towing boats), water pumps, water hoses, water inlet holes and exhaust holes, etc.; when assembling the above plugging materials, the tools mainly include oil hammers, hand hammers, etc. After the plugging materials are transported to the site of the mouth, a water-filled net bag component is made, that is, the longitudinal ropes (thicker in diameter) and the transverse ropes (thinner in diameter) are tied together to form a net bag rope, and the water-filled bag is wrapped and set, and the retaining ropes with counterweights are tied to both ends of the net bag, forming the water-filled net bag component and the retaining rope as a whole, and the retaining rope can prevent the net bag from being washed away by the water flow after entering the water, ready for occupation.

[0033] Then, the mouth is occupied, blocked, and sealed: first, the dikes on both sides of the mouth are repaired and blocked (also called wrapping in the existing structure) to prevent the mouth from expanding; secondly, piles are driven in and the outer surface of the prepared water-filled net bag is covered with net bag ropes; thirdly, the water-filled net bag assembly is connected to the water pump, and the water pump is started to fill the bag with water. After the bag is full, the water inlet and exhaust holes are sealed with a cover; fourthly, the ropes at both ends of the bag are tied to the pre-made fixed piles (fixed bag assembly); fifthly, the water-filled net bag assembly is pushed into the water to implement the underwater occupation operation. After the water-filled net bag assembly enters the riverbed, the ropes at both ends of the bag are tied to the fixed piles. The bottom hook rope is tied to the top pile to fix the net bag; sixth, as the water-filled net bag assembly continues to advance, the net bag wall moves away from the shore, and anchors or gabions should be dropped in front of and behind the entrance to pull the net bags with ropes, or towboats should be used to pull the net bags with ropes to ensure the stability of the body; seventh, the back water side of the body (the water wall composed of the above-mentioned multiple water-filled net bag assemblies) is filled in time to follow up and stabilize the water bag body to ensure the stability of the body; eighth, the seam is closed and the breath is sealed. After the last net bag is pushed into the entrance to close the seam, the filling force on the rear side of the water-filled net bag assembly seam should be accelerated to ensure the success of the blocking and closing.

[0034] Among them, the embankments on both sides of the mouth are wrapped to form a plug. The wrapping methods include geotextile bottom and bank protection, willow stone pillow or willow stone building bank protection, earthbag cage or stone bag cage bank protection to prevent the mouth from continuing to expand.

[0035] Furthermore, the specific steps of step one include:

[0036] a. Driving piles: The bag-fixing assembly adopts pile-fixing piles, and mechanical or manual piling is used on the top of the bank on both sides of the gate; among them, mechanical piling is preferred;

[0037] b. Weaving a mesh bag rope and wrapping the mesh bag rope around the outer surface of the water-filled bag: laying longitudinal ropes and transverse ropes along the water flow direction at the entry position to form a mesh bag bottom, and placing the unfilled water-filled bag on the mesh bag bottom, weaving a mesh top according to the diameter (width) and length of the bag body, and wrapping the mesh bag rope in a mesh bag shape to form a complete water-filled mesh bag assembly;

[0038] c. Fill the water bag with water and seal the water inlet and exhaust holes: connect the water inlet of the water bag with the water outlet of the water pump, and seal the bag body with a hose connector. Then start the water pump to fill the water bag with water, and exhaust excess gas through the exhaust hole. Then quickly seal the exhaust hole and water inlet with a cap.

[0039] d. Form a water-filled net bag assembly, drive the stakes and mooring ropes, and prepare for occupation: drive one or more rows of stakes on both sides of the occupation position on the shore, and the spacing of the stakes (the distance between two adjacent stakes) is generally 1.0 meters. For example, drive 5 stakes side by side with a distance of 4 meters; tie one end of the mooring rope to the stakes at both ends of the net bag rope in advance, and connect the other end of the mooring rope to the net bag rope at both ends of the water-filled bag and tie it firmly. The formed water-filled net bag assembly and the mooring ropes at both ends are a firm whole. Its working principle and process are as follows:

[0040] Each solid bag assembly includes two solid piles, which are respectively fixed on the bank of the dam, and the outer end of the retaining rope is tied to the solid pile. The length of each solid pile is 1 meter to 2 meters, and the diameter of each solid pile is 10 centimeters to 25 centimeters. The grounding end of each solid pile is provided with a cone, and the length of the cone is 10 centimeters to 20 centimeters. A pile-starting hole is penetrated at the end of each solid pile away from the cone, and the diameter of the pile-starting hole is 12 millimeters to 16 millimeters; a pulling rope is inserted through the pile-starting hole at the top of each solid pile.

[0041] The bag assembly is arranged along the bank of the embankment. In order to facilitate mechanical or manual piling, the bag assembly adopts steel or iron structured piles. The diameter of the piles is 10 cm to 25 cm and the length is 1 m to 2 m, that is, the diameter of the pile is proportional to the length of the pile. The longer the length of the pile, the larger the diameter of the pile. Among them, the piles with a length of 1 m to 2 m are mainly used for sandy soil and piling on the shore, and the piles with a length of 1.5 m to 2 m are mainly used for piling in clay soil and in water. The diameter of the cone at the tip of the pile is consistent with the diameter of the pile. A pile starting hole is set at 18 cm to 20 cm from the top of the pile. The diameter of the pile starting hole is 12 mm to 16 mm, which is convenient for mechanical or manual pulling out of the pile.

[0042] As the water-filled mesh bag assembly is occupied, the mouth gradually shrinks, and it is necessary to drive piles and tie ropes on the upstream side of the water-filled mesh bag assembly to pull the water-filled mesh bag assembly. When the upstream side of the mouth cannot drive piles due to the water depth and rapid current, a pre-prepared anchor or gabion should be thrown into the water in the water in the front end direction of the water-filled mesh bag assembly by boat, and a rope should be tied from the anchor or gabion to connect it with the rope of the water-filled mesh bag assembly to use it as a solid bag assembly. That is, when each of the solid bag assemblies includes a ground anchor, each of the ground anchors is thrown into the water area and touches the bottom, and the external end of the rope is tied to the ground anchor. The ground anchor can effectively pull the water-filled bag, fix the water-filled bag, and prevent the water-filled bag from being washed away by the rapid current, or the water-filled mesh bag assembly can be pulled by a towing boat.

[0043] Furthermore, the specific steps of step 2 include:

[0044] e. Before pushing and throwing, tie the ropes at both ends of the water-filled net bag assembly to the driven piles through live buckles;

[0045] f. Grasp the ends of the ropes at both ends of the water-filled net bag assembly, use machinery or manual labor to push the water-filled net bag assembly to the occupied position, and then tie the ropes to the fixed piles for fixation;

[0046] g. When the mouth is gradually narrowed to 3 to 5 meters as the water-filled net bag components are continuously occupied and thrown in, the closing operation is carried out. When closing the mouth, it is necessary to prepare sufficient water-filled net bag components and other plugging materials to avoid interruptions in closing the mouth and losses caused by water impact.

[0047] Among them, at the beginning of occupation and during the entire occupation process, a group of bottom hook ropes and top piles are set. The number of top piles and bottom hook ropes is determined according to the length of the bag body, and the spacing between two adjacent bottom hook ropes is 1 meter; the rope can ensure the stability of the body in the direction of the water flow, while the bottom hook rope ensures the stability of the body in the direction perpendicular to the water flow. The two interact and depend on each other to jointly maintain the stability of the water bag wall. The top pile is fixed on the shore, one end of the bottom hook rope is tied to the top pile, and the other end of the bottom hook rope is sequentially intertwined and wrapped around each water-filled net bag component thrown into the breach, and then tied to the top pile, so that the bottom hook rope is constantly pulled back during occupation, so that each water-filled net bag component is connected to each other to form a continuous wall to resist water flow and narrow the mouth.

[0048] Furthermore, the step 2 further includes:

[0049] h. After the mouth is closed, the air-holding operation is performed: the air-holding operation first requires timely adding soil (following up the backfill material) on the backwater side of the water-filled mesh bag assembly, and then the height and weight of the top water-filled mesh bag assembly are maintained. One is to prevent the water level from being too high and collapsing the water-filled mesh bag assembly after the closure and air-holding, and the other is to reduce the flow rate in the gap between the water-filled mesh bag assemblies, etc., so as to avoid the soil material of the backing body from being washed away by the water flow and complete the air-holding operation.

[0050] Furthermore, the net bag rope is made of hemp rope, palm rope or woolen rope, and other types of ropes can also be used instead; the counterweight block is made of iron weight, or sand and gravel bag, or concrete block, and other heavy objects can also be used instead.

[0051] On the other hand, the specific steps of step one include:

[0052] A. Lay ground film at the entrance;

[0053] B. Lay water-filled bags on the ground film. The laying range of the water-filled bags should be at least 2 meters beyond the exit door, and the water-filled bags should be tightly combined with the protective walls on both sides of the exit door;

[0054] C. After the water-filled bag is laid, connect the water outlet of the water pump with the water inlet of the water-filled bag, start the water pump to fill the water into the water-filled bag until the water-filled bag is full of water. The outer surface of the water-filled bag is covered with a mesh bag rope, and ropes are provided at both ends of the mesh bag rope to form a water-filled mesh bag assembly.

[0055] Furthermore, the specific steps of step 2 include:

[0056] D. The bag fixing assembly adopts expansion screws. The expansion screws are fixed at the ropes on both sides of the water-filled net bag assembly. The bag body is fixed by tying ropes or pegs, or by using sand and gravel bags and earth bags (stacked platforms) to fix the bag body.

[0057] E. After the water-filled bags are fixed, the stacked water-filled bags are sealed to complete the blocking operation. This type of blocking operation is suitable for blocking small distances such as tunnel entrances or subway entrances.

[0058] The net bag rope is made of a flat plastic belt or a woolen belt, and other types of ropes and cables can also be used instead.

[0059] In the above process, the role of the net bag rope is to ensure the tolerance and filling capacity of the water-filled bag. A water-filled bag made of a material with higher tolerance can be selected, and ropes can be directly passed through both ends of the water-filled bag. This step can be replaced by using the net bag rope by setting reserved holes on both sides of the water-filled bag to pass the ropes.

[0060] In summary, the beneficial effects of the present invention are as follows:

[0061] The present invention provides a water-filled mesh bag type plugging device and a plugging method thereof, and blocks the mouth by stacking and superimposing water-impermeable and airtight water-filled mesh bag components, wherein the water in the water-filled bag is filled with water to achieve local material use, with high speed, high efficiency, and less material input, which further effectively speeds up the rescue time, and the implementation method is simple and convenient, reduces disaster losses, and is easy to promote and use.

Figure 5 As shown, each of the anchors 114 is thrown into the water area and touches the bottom, and the external end of the retention rope 104 is tied to the anchor 114, wherein the water-filled net bag device also includes a water pump for filling the water-filled bag 101 with water, and the water outlet of the water pump is consistent in size with the water inlet hole 109 of the water-filled bag 101.

[0081] Its working principle and process are as follows:

[0082] The two groups of plugs 107 are respectively covered on the dike head ports of the dike breach, and can wrap the dike heads on both sides of the dike breach or the mouth, that is, wrap the dike breach or the mouth, which can effectively prevent the dike head from being eroded by water flow, which causes the breach or the mouth to continue to expand; a number of water-filled mesh bag assemblies are arranged between the two groups of plugs 107, that is, a sealed and waterproof wall is formed between the two groups of plugs 107, and each water-filled bag 101 in the wall is fixed by a retaining rope 104, a mesh bag rope 102, and a solid bag assembly, wherein a plurality of water-filled bags 101 are fixed between the two groups of plugs 107 by a same number of solid bag assemblies, the structure is stable and firm, simple and reasonable, and the implementation is The method is more convenient, reduces the input of manpower and material resources, and avoids the problem of difficult material transportation in the existing plugging and repairing methods. It can directly realize the use of local water materials. On the other hand, each water-filled bag 101 is provided with a water inlet hole 109 and an exhaust hole 108. While filling the water-filled bag 101 with water through the water inlet hole 109, the air inside the water-filled bag 101 can be discharged through the exhaust hole 108, which effectively improves the water filling efficiency, that is, speeds up the supply of plugging and repairing materials, and effectively improves the rate of plugging and repairing operations. The above-mentioned solid bag assembly adopts a ground anchor 114, which can effectively pull the water-filled bag 101, fix the water-filled bag 101, and prevent the water-filled bag 101 from being washed away by the rapids. In the above process, the solid bag assembly includes a fixed pile (fixed pile or wooden pile) (such as Figure 1 as shown), or ground anchor (as Figure 5 as shown), or a towing vessel (as Figure 6 shown).

[0083] The water pump can timely fill the water bag 101 with water in a short time. The water outlet of the water pump is consistent with the diameter of the water inlet hole 109 of the water bag 101, which is convenient for connecting the water outlet of the water pump with the water inlet hole 109 to maintain the efficiency of water filling. The water pump can adopt a common water pump integrated machine on the market. The larger the volume of the water bag 101, the greater the power of the water pump integrated machine used. For example, the size of the water inlet of the water bag 101 is set to 2 inches, 2.5 inches, 3 inches, 4 inches, and 6 inches. The water output of the water pump integrated machine used is selected to be consistent with the water output of 2 inches, 2.5 inches, 3 inches, 4 inches, and 6 inches.

[0084] As the water-filled mesh bag assembly is occupied, the mouth gradually shrinks, and it is necessary to drive a pile 111 on the upstream side of the water-filled mesh bag assembly and tie a retaining rope 104 to pull the water-filled mesh bag assembly. When the pile 111 cannot be driven on the upstream side of the mouth due to the water depth and rapid current, a pre-prepared anchor 114 or gabion should be thrown into the water in the water in the front end direction of the water-filled mesh bag assembly by a boat, and a rope should be tied from the anchor 114 or the gabion to connect it to the retaining rope 104 of the water-filled mesh bag assembly to use it as a solid bag assembly, that is, each of the solid bag assemblies includes an anchor 114 or a gabion.

[0085] like Figure 4 As shown, the length of each of the fixed piles 111 is 1 meter to 2 meters, the diameter of each of the fixed piles 111 is 10 centimeters to 25 centimeters, the grounding end of each of the fixed piles 111 is provided with a cone 112, the length of the cone 112 is 10 centimeters to 20 centimeters, and the end of each of the fixed piles 111 away from the cone 112 is penetrated by a pile opening hole 113, the diameter of the pile opening hole 113 is 16 millimeters, and the top of each fixed pile 111 is inserted with a pull rope 115 through the pile opening hole 113. The diameter of the water bag 101 is 0.3 meters to 3.0 meters, the length of the water bag 101 is 3 meters to 20 meters, the diameter of the water inlet hole 109 is 2 inches to 6 inches, the diameter of the exhaust hole 108 is 2 inches to 6 inches, the diameter of the net bag rope 102 is 2 centimeters to 3 centimeters, the length of the net bag rope 102 is 10 meters to 20 meters, the diameter of the retention rope 104 is 3 centimeters to 5 centimeters, and the weight of the counterweight 103 is 1 / 100 to 1 / 1000 of the weight of the water bag 101 after being filled with water.

[0086] Its working principle and process are as follows:

[0087] The diameter of the pile 111 is 10 cm to 25 cm, and the length is 1 m to 2 m, that is, the diameter of the pile 111 is proportional to the length of the pile 111, and the longer the length of the pile 111, the larger the diameter of the pile 111; the piles 111 with a length of 1 m to 2 m are mainly used for pile driving in sandy soil and on shore, and the piles 111 with a length of 1.5 m to 2 m are mainly used for pile driving in clay soil and in water; the diameter of the conical piece 112 at the pile tip of the pile 111 is consistent with the diameter of the pile 111; a pile opening hole 113 is set at 18 cm to 20 cm from the pile top of the pile 111, and the diameter of the pile opening hole 113 is 12 mm to 16 mm, so that the pile 111 can be pulled out mechanically or manually;

[0088] The water-filled bag 101 with a diameter of 0.3m to 0.8m and a length of 10m to 20m is used for blocking water flow in urban flood control, repairing flood control sub-dikes at intersections or tunnels or subway entrances or dike projects; the water-filled bag 101 with a diameter of 0.8m to 2m and a length of 3m to 10m is used for re-blocking dike mouths; the water-filled bag with a diameter of 2m to 3m and a length of 8m to 10m is used for closing dike mouths; wherein, the sizes of the water inlet hole 109 and the exhaust hole 108 on the water-filled bag 101 are proportional to the size of the water-filled bag 101, that is, the thicker the diameter of the water-filled bag 101 and the longer the length, the larger the sizes of the water inlet hole 109 and the exhaust hole 108; the above-mentioned water-filled bag 101 can be made of impermeable bags, such as rubber bags, which can be divided into flood control water-filled net bag devices and water-filled net bag devices according to their uses and water depths. A reused water-filled net bag device for plugging the mouth of a dike, wherein the water bag 101 of the water-filled net bag device for urban flood control has a small diameter and a long length, for example, when the diameter of the water bag 101 is 0.3 meters, the length is 20 meters, when the diameter of the water bag 101 is 0.5 meters, the length is 10 meters or 15 meters, and when the diameter of the water bag 101 is 0.8 meters, the length is 10 meters; the water bag 101 of the reused water-filled net bag device for plugging the mouth of a dike has a large diameter and a short length, for example, when the diameter of the water bag 101 is 1 meter, the length is 10 meters, when the diameter of the water bag 101 is 1.5 meters, the length is 8 meters, when the diameter of the water bag 101 is 1.8 meters, the length is 6 meters or 8 meters, when the diameter of the water bag 101 is 2 meters, the length is 6 meters and 8 meters, and when the diameter of the water bag 101 is 3 meters, the length is 6 meters.

[0089] A mesh bag rope 102 with a length of 10 to 20 meters is tied to the outer surface of the water-filled bag 101 to form a net bag, and a retention rope 104 with a length of 10 to 30 meters is tied to both ends of the mesh bag rope 102. The other end of the retention rope 104 is tied to a fixed pile 111, which forms a pulling effect on the water-filled bag 101 to prevent it from being washed away by the water flow. The diameters of the mesh bag rope 102 and the retention rope 104 are proportional to the water flow rate, that is, the greater the water flow rate at the mouth or breach, the thicker the diameters of the mesh bag rope 102 and the retention rope 104.

[0090] After the water-filled bag 101 is pushed or thrown into the water, in order to prevent the water-filled bag 101 from having difficulty in touching the bottom or drifting with the water flow, counterweights 103 should be added along the ropes 104 at both ends of the water-filled bag 101. The size of the counterweight 103 should be determined according to the water flow and the volume of the water-filled bag 101. If the flow rate is large and the volume of the water-filled bag 101 is large, the weight of the counterweight 103 should be increased accordingly, and the weight of the counterweight 103 should be kept at 1 / 100 to 1 / 1000 of the weight of the water-filled bag 101 after being filled with water; the counterweight 103 is made of iron weights, or gravel bags, or concrete blocks, such as a 25 kg standard pound or a 25 kg gravel bag or concrete block.

[0091] Embodiment 5, as Figure 7As shown, a plugging method of a water-filled mesh bag plugging device is provided, comprising:

[0092] Step 1, prepare plugging materials before construction: the plugging materials include a water-filled bag 101, a water-filled bag 101, a counterweight 103, a retaining rope 104, a bag assembly and a water pump (not shown in the figure). After the plugging materials are transported to the site of the mouth, the water-filled bag 101 is filled with water by the water pump, and then the net bag rope 102 is wrapped around the water-filled bag 101 and placed. At the same time, the retaining rope 104 with the counterweight 103 is tied to the two ends of the net bag rope 102 to form a water-filled net bag assembly, ready for occupation;

[0093] Step 2, push and throw the prepared water-filled mesh bag assembly into the mouth, and carry out the occupying operation until it is closed and the air is sealed to complete the blocking operation, wherein the remaining rope 104 on each water-filled mesh bag assembly is tied to the pre-fixed solid bag assembly for fixing.

[0094] Furthermore, the step one also includes wrapping the dikes on both sides of the entrance before construction, and the wrapping methods include wrapping the dikes with geotextile revetment and bottom protection, wrapping the revetment with willow stone pillows or willow stone building boxes, and wrapping the revetment with earthbag cages.

[0095] Furthermore, the specific steps of step one include:

[0096] a. Driving piles 111: The bag-fixing assembly adopts piles 111, and mechanical or manual pile driving is used on the top of the bank on both sides of the gate;

[0097] b. Weaving a mesh bag rope 102 and wrapping the mesh bag rope 102 around the outer surface of the water-filled bag 101;

[0098] c. Fill the water bag 101 with water and seal the water inlet hole 109 and the exhaust hole 108: connect the water inlet hole 109 of the water bag 101 to the water outlet of the water pump and seal them with a water tape, then start the water pump to fill the water bag 101 with water, and exhaust the excess gas through the exhaust hole 108, and then quickly seal the exhaust hole 108 and the water inlet hole 109;

[0099] d. Form a water-filled net bag assembly and prepare to occupy: tie ropes 104 at both ends of the water-filled net bag assembly;

[0100] The net bag rope 102 includes a longitudinal cable 106 and a transverse cable 105 for tying the bag body, and the longitudinal cable 106 and the transverse cable 105 are staggered to form a net bag shape.

[0101] Furthermore, the specific steps of step 2 include:

[0102] e. Before throwing, tie the ropes 104 at both ends of the water-filled net bag assembly to the driven piles 111 through a snap fastener. After throwing the bag, tie it tightly after the water-filled net bag assembly reaches the bottom;

[0103] f. Grasp the ends of the ropes 104 at both ends of the water-filled net bag assembly, use a machine or manual method to push the water-filled net bag assembly to the occupied position, and then tie the ropes 104 to the fixed piles 111 for fixing;

[0104] g. When the mouth gradually narrows to 3m-5m as the water-filled net bag components are continuously thrown in, the closing operation is performed;

[0105] Among them, at the beginning of the occupation and during the entire occupation process, a group of bottom hook ropes 117 and top piles 116 are set. The number of top piles 116 and bottom hook ropes 117 is determined according to the length of the bag body, and the spacing between two adjacent bottom hook ropes 117 is 1 meter; the rope 104 can ensure the stability of the body in the direction of the water flow, while the bottom hook rope 117 ensures the stability of the body in the direction perpendicular to the water flow. The two interact and depend on each other to jointly maintain the stability of the water bag wall. The top pile 116 is fixed on the shore, one end of the bottom hook rope 117 is tied to the top pile 116, and the other end of the bottom hook rope 117 is sequentially intertwined and wrapped around each water-filled net bag component thrown into the breach, and then tied to the top pile 116, so that the bottom hook rope 117 is continuously pulled back during the occupation, so that each water-filled net bag component is connected to each other to form a continuous wall to resist the water flow and narrow the mouth.

[0106] Furthermore, the step 2 further includes:

[0107] h. After the mouth is closed, the air-sealing operation is performed: the air-sealing operation first requires timely adding soil on the backwater side of the water-filled mesh bag assembly to seal the air, and then maintaining the weight of the top water-filled mesh bag assembly to reduce the gap between the water-filled mesh bag assembly and the water-filled mesh bag assembly. Finally, geotextile can be laid from bottom to top on the water-facing side of the water-filled mesh bag assembly to form a water-proof barrier to complete the air-sealing operation.

[0108] Furthermore, the water-filled bag 101 is made of hemp rope or woolen rope, and the counterweight block 103 is made of an iron scale, or a sand bag, or a soil bag, or a concrete block.

[0109] In the above-mentioned method for plugging a breach, the water-filled net bag assembly can be thrown into the breach, wherein the method of throwing the water-filled net bag assembly into the breach includes three methods: shore throwing, ship throwing and towing throwing;

[0110] like Figure 8 and Fig. 9As shown, for example, shore throwing is to push and throw the water-filled net bag assembly directly from the shore into the breach, which is suitable for plugging breaches close to the shore. In addition to direct manual pushing and throwing and mechanical pushing and throwing, specifically, two groups of inflatable balls can be placed on the shore of the breach as a base, and then the unfilled water-filled net bag assembly is placed on the base, and then the water-filled operation is performed. After the water-filling operation is completed, the group of inflatable balls closer to the breach of the two groups as the base is deflated to form a height difference at the bottom of the water-filled net bag assembly, so that the water-filled net bag assembly with a larger volume after being filled with water automatically rolls into the breach. In this process, Figure 8 As shown, two groups of top piles 116 need to be set on both sides of the breach, and bottom hook ropes 117 are wound around the top piles 116. The bottom hook ropes 117 are wound around each water-filled net bag assembly thrown into the breach in turn, and the water-filled net bag assembly thrown into the breach is fixed inside the breach, so that multiple water-filled net bag assemblies can be stacked together layer by layer.

[0111] For example, the ship throw is to place the water-filled net bag assembly on the ship, which is suitable for sealing breaches far from the shore and breaches with larger openings. Fig.10 As shown, the bag-throwing boat 119 is fixed to the position where the breach needs to be sealed by a cable, and the water in the water-filled net bag assembly is filled with water on the boat. During the filling process of the water-filled net bag assembly, the water-filled net bag assembly is placed on one side of the bag-throwing boat 119. After the water-filled net bag assembly is filled with water, the water-filled net bag assembly can be pushed into the water with less thrust by means of a slight tilt of the hull. In the above process, the bottom hook rope 117 can be tied to the keel 120 of the bag-throwing boat 119.

[0112] For example, towing and throwing is to fill the water-filled net bag assembly with water on the shore. At this time, a towing rope is added to the water-filled net bag assembly, and one end of the towing rope (at the same time, the towing rope can replace the bag-fixing function of the retaining rope) is fixed on the shore. By pulling the towing rope, the water-filled net bag assembly is towed and exiled to the occupied position. During this process, the user can tow it on the boat or on the shore to adapt to the placement of the water-filled net bag assembly in different positions.

[0113] Furthermore, in the method for plugging the breach, multiple water-filled mesh bag assemblies are stacked and connected with each other to form a wall. Before the mouth is closed and the air-sealing operation is performed, in order to increase the stability of the wall, a group of cross-structured riding piles can be fixed on the back water surface of the wall, and the bottom of the riding piles is inserted into the deep bottom of the water at the breach. At the same time, a group of fixed pull ropes are tied to the center of the riding piles, and the other end of the fixed pull rope is tied to an anchor or a cage or a towing boat to increase the stability of the wall. Then the air-sealing operation is performed. This process can effectively improve the wall's tolerance to water flow impact and increase its stability.

[0114] Embodiment 6:

[0115] On the other hand, a method for blocking the orifice with a water-filled net bag for subway entrances and underpass tunnel entrances is provided. The specific steps of Step 1 include:

[0116] A. Lay a plastic film at the orifice.

[0117] B. Lay the water-filled bag 101 on the plastic film. The laying range of the water-filled bag 101 is at least 2 meters beyond the orifice, and the water-filled bag 101 is kept in close contact with the protective walls and the ground on both sides of the orifice.

[0118] C. After the water-filled bag 101 is laid, connect the water outlet of the water pump to the water inlet hole 109 of the water-filled bag 101, and start the water pump to fill the water-filled bag 101 with water until the water-filled bag 101 is full of water. The outer surface of the water-filled bag 101 is covered with a net bag rope 102, and stay ropes 104 are arranged at both ends of the net bag rope 102 to form a water-filled net bag assembly.

[0119] In the above process, when placing the above water-filled net bag assembly at the subway entrance or tunnel entrance, a layer of plastic film needs to be covered on the bottom surface of the water-filled net bag assembly to be placed. This plastic film can be a plastic sheet. Then, place three water-filled net bag assemblies stacked together to form a "pin" - shaped frame on the plastic film, which can effectively prevent water quality from seeping downward or outside the water bag, ensuring the sealing performance.

[0120] Its working principle and process are as follows:

[0121] As Fig.11 and Fig.12 shown, after sufficient water-filled bags 101 are prepared, water filling preparation is carried out through the water pump. At this time, the water-filled bag 101 is cylindrical after being filled with water, and the contact area with the bottom surface is small. Under the action of water flow scouring or hydrodynamic pressure, it is extremely easy to lose stability and roll or slide, losing stability. As Fig.11 shown, therefore, after the water-filled bag 101 is filled with water, group the water-filled bags 101 in groups of three to form a "pin" - shaped structure, tie the water-filled bags 101 together, increase the contact area and the height of the wall formed by the water-filled net bag assembly, maintain the height of the water level for enclosure, and increase the counterweight to promote the close contact between the water-filled net bag assembly at the lower part of the wall and the ground, preventing water from entering the subway entrance or underpass tunnel through the gap between the bag body and the ground, achieving the purpose of blocking the orifice of the subway or underpass tunnel.

[0122] During the above process, after the water-filled bag 101 is arranged, the water inlet hole 109 is connected to the water outlet of the water pump. When the water pump is used to flush water into the water-filled bag 101, it is necessary to timely pry the position of the water-filled bag 101 so that the water-filled bags 101 in a single or a group of two or three are parallel to the subway or tunnel entrance to prevent them from being entangled with each other and in close contact with the protective wall at the subway or tunnel entrance. For example, when the water-filled bag 101 is filled with water to 60% of the full bag, When the water bag 101 is filled to 70% to 80% of its full size, the bottom hook rope 105 is retracted, tightened and tied into a slipknot. When the water bag 101 is filled to 70% to 80% of its full size, the bottom hook rope 105 is tied firmly and the water bag 101 is continued to be filled to 80% to 90% of its full size, until the water bag 101 at the top can press the water bag 101 at the bottom into an elliptical or flat state, so as to increase the contact area between the water bag 101 and the ground, thereby increasing the stability and water-avoiding effect of the water bag 101.

[0123] Furthermore, the specific steps of step 2 include:

[0124] D. The bag fixing assembly uses expansion screws. The expansion screws are fixed at the ropes on both sides of the water-filled net bag assembly.

[0125] The water-filled net bag assembly can be fixed directly by expansion screws without setting ropes at both ends of the water-filled net bag assembly;

[0126] E. After the water-filled bags 101 are fixed, the stacked water-filled bags 101 are sealed to complete the blocking operation.

[0127] Furthermore, the net bag rope 102 is made of a flat plastic belt or a woolen belt.

[0128] Its working principle and process are as follows:

[0129] In the above process, there are two ways to fix the water-filled bag 101. One is to use counterweight pressure protection, and the other is to use collision screws to fix it. The counterweight pressure protection method is suitable for basically static water flow or the situation where the scouring force of the water flow and the wind and wave fluctuation force are small; the fixing method using expansion screws is suitable for the situation where the water flow rate is large or the scouring force and the wind and wave fluctuation force are large. In order to prevent the water-filled bag 101 from sliding or rolling, expansion screws are used on both sides of the water-filled bag 101, and the water-filled bag 101 is fixed by tying it with a woolen rope, or a stake 116 is driven to tie the bottom hook rope 117 to fix it.

[0130] To summarize, for example, a water-filled bag 101 with a diameter of 0.3 to 0.8 meters and a length of 10 to 20 meters is used for blocking water flow in urban flood control, repairing flood control sub-dikes at intersections or tunnels or subway entrances or dike projects; a water-filled bag 101 with a diameter of 0.8 to 2 meters and a length of 3 to 10 meters is used for re-blocking dike mouths; a water-filled bag with a diameter of 2 to 3 meters and a length of 8 to 10 meters is used for closing dike mouths; wherein, the sizes of the water inlet hole 109 and the exhaust hole 108 on the water-filled bag 101 are proportional to the size of the water-filled bag 101, that is, the thicker the diameter of the water-filled bag 101 and the longer the length, the larger the sizes of the water inlet hole 109 and the exhaust hole 108; the above-mentioned water-filled bag 101 can be made of impermeable bags, such as rubber bags, which can be divided into flood control water-filled nets according to their use and water depth. The invention relates to a reused water-filled net bag device for plugging the mouth of a dike, wherein the water bag 101 of the water-filled net bag device for urban flood control has a small diameter and a long length, for example, when the diameter of the water-filled bag 101 is 0.3 meters, the length is 20 meters, when the diameter of the water-filled bag 101 is 0.5 meters, the length is 10 meters or 15 meters, and when the diameter of the water-filled bag 101 is 0.8 meters, the length is 10 meters; the water bag 101 of the reused water-filled net bag device for plugging the mouth of a dike has a large diameter and a short length, for example, when the diameter of the water-filled bag 101 is 1 meter, the length is 10 meters, when the diameter of the water-filled bag 101 is 1.5 meters, the length is 8 meters, when the diameter of the water-filled bag 101 is 1.8 meters, the length is 6 meters or 8 meters, when the diameter of the water-filled bag 101 is 2 meters, the length is 6 meters and 8 meters, and when the diameter of the water-filled bag 101 is 3 meters, the length is 6 meters.

[0131] The present invention provides a method for blocking an opening with a water-filled mesh bag, wherein the opening is blocked by stacking and superimposing water-impermeable and airtight water-filled mesh bag components, wherein the water in the water-filled bag is filled with water to achieve local material acquisition, with a fast speed, high efficiency, and less material input, which further effectively speeds up the rescue time, and the implementation method is simple and fast, can avoid unnecessary losses, and has a wider scope of application.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
