Description

Technical Field

[0001] The present application relates to the field of water conservancy emergency rescue technology, and in particular to an integrated pipe burst emergency rescue device and a preparation method and a packaging method thereof. Background Art

[0002] Piping is the formation of holes in the foundations of hydraulic structures such as dams during flood season when soil particles are carried out by water. Piping during flood season is one of the major threats to the safety of river dams and is a common hazard in flood control efforts. Currently, anti-filtration wells are a common emergency response to piping hazards and have long been proven to be the most effective method. These wells utilize pre-stored, locally stored flood control sand and gravel, manually loaded and transported, and laid out in layers around the piping outlet. A filter layer is installed at the bottom to prevent soil particle loss, and an upper well is used to retain water and raise the water level to balance water pressure. However, this method has drawbacks such as high labor input, high material requirements, and lengthy operations. This makes it difficult to meet the critical demands of flood control efforts. Furthermore, limited on-site accessibility can lead to insufficient machinery and personnel, as well as a shortage of materials, which can easily delay effective blocking efforts and ultimately lead to levee failure.

[0003] In summary, the technical problems existing in the relevant technologies need to be improved. Summary of the Invention

[0045] Research on new technologies, materials, and techniques for rapid pipe burst rescue is relatively rare, both domestically and internationally. Piping bursts occur frequently, so rescue teams typically have extensive experience responding. However, because they often occur in remote locations, mechanized equipment is difficult to reach, forcing traditional methods to be employed. Traditionally, a well is constructed at the burst site using woven bags filled with soil. Filter material is then gradually laid inside the well, followed by a drainage pipe. While this filter well construction method is relatively mature and widely used, during floods, sand and gravel are relatively scarce nearby, making bagging, transporting, and construction time-consuming and labor-intensive. In recent years, improvements have been made to the well structure using water-filled airbags and bottomless iron barrels. However, because the location of the pipe burst can vary, such as underwater or on slopes, these new well structures lack the inherent stability to withstand these complex environments and are therefore still not widely used. In addition, bulk sand and gravel are still used as filter layer materials in the construction of the well, which also faces the problems of materials being easily carried away by water flow, large losses, and the need for tools or more manpower to transport materials.

[0046] The core idea of ​​pipe burst rescue is "soil preservation and drainage". Although traditional anti-filtration well technology is effective, it consumes a lot of manpower, materials and time. This is mainly because when a pipe burst occurs, sand and gravel must be obtained nearby, and the nearest flood control sand and gravel yard is usually hundreds of meters or even kilometers away. Moreover, when a flood occurs, transportation conditions deteriorate significantly, and manual transportation is often required. In addition, filling sandbags on site also consumes a lot of manpower and time. Pipe burst rescue becomes a human wave tactic to deal with random emergencies.

[0047] In view of this, an embodiment of the present application provides an integrated device for emergency rescue of pipe bursts, such as Figure 1 As shown, Figure 1Schematic diagram of the structure of an integrated pipe burst rescue device provided in an embodiment of the present application. The device includes: a first water-permeable module 100, a second water-permeable module 200, and a third water-permeable module 300. The first water-permeable module 100, the second water-permeable module 200, and the third water-permeable module 300 are all cylindrical in shape, and the bottom surfaces of the cylinders are equal in size and shape. The bottom surface of one end of the second water-permeable module 200 is connected to the bottom surface of one end of the first water-permeable module 100, and the bottom surface of one end of the third water-permeable module 300 is connected to the bottom surface of the other end of the second water-permeable module 200. The materials used to make the first water-permeable module 100, the second water-permeable module 200, and the third water-permeable module 300 include a porous material with water permeability. The water permeability of the porous material in the first water-permeable module 100 is less than that of the porous material in the second water-permeable module 200, and the water permeability of the porous material in the second water-permeable module 200 is less than that of the porous material in the third water-permeable module 300.

[0048] Specifically, to ensure secure connections, the first, second, and third permeable modules 100, 200, and 300 are connected during the manufacturing process of the integrated piping rescue device. The first, second, and third permeable modules 100, 200, and 300 are integrally formed to form the integrated piping rescue device. The first, second, and third permeable modules 100, 200, and 300 are all cylindrical in shape, meaning each module includes one or more side surfaces, with a bottom surface at each end. Because the integrated piping rescue device is manufactured in the same mold, to maintain consistent specifications for ease of handling and minimize damage during transport, the bottom surfaces of the first, second, and third permeable modules 100, 200, and 300 are designed to be the same shape and size. This reduces damage during transport due to angular shapes or sizes. By combining the different porous materials of the first, second, and third permeable modules 100, 200, and 300, the structure functions as a filter layer for pipe burst rescue. For porous materials, larger pores increase permeability, while smaller pores decrease permeability. The first permeable module 100 has the lowest permeability, followed by the second, 200, and finally the third, 300. The bottom surface of the end of the first permeable module 100 not connected to the second, 200, is directly placed over the pipe burst outlet. Because the pores of the first permeable module 100 are smaller than the soil particles, soil conservation and drainage are achieved during pipe burst control. Soil is retained beneath the first permeable module 100, while water flows out through the second and third permeable modules 200 and 300. The second and third permeable modules 200 and 300 have higher permeabilities than the first permeable module 100, enabling secondary and tertiary filtration of the water flow and rapid water outflow.

[0049] In some embodiments, the porous material is permeable concrete. The aggregate particle size of the permeable concrete in the first permeable module 100 is smaller than that in the second permeable module 200. The aggregate particle size of the permeable concrete in the second permeable module 200 is smaller than that in the second permeable module 200.

[0050] Specifically, permeable concrete, composed of coarse aggregate, cement, and water, has a honeycomb-like porous structure. Larger particle sizes correlate with higher porosity and enhanced permeability, while smaller particle sizes result in reduced porosity and decreased permeability. This structure exhibits excellent permeability and a certain strength, effectively filtering sediment while allowing water to flow through, thus providing a filtration and drainage function. Therefore, permeable concrete is the preferred porous material. To control the permeability of the integrated piping rescue device, the first permeable module 100 has the smallest aggregate particle size, followed by the second permeable module 200, and the third permeable module 300 has the largest aggregate particle size, achieving a "fine-medium-coarse" layered filtration and drainage structure.

[0051] In some embodiments, the side height of the first permeable module 100 is greater than the side height of the second permeable module 200, and the side height of the second permeable module 200 is equal to the side height of the third permeable module 300. Specifically, since the first permeable module 100 is in direct contact with the piping outlet and serves as the first line of defense for soil conservation and drainage, to ensure the filtration capacity of the first permeable module 100, the side height of the first permeable module 100 is set to be the highest, that is, the thickness of the first permeable module 100 is the largest. The side heights of the second and third permeable modules 200 and 300 are next. The side heights of the second and third permeable modules 200 and 300 can be the same or different and can be adjusted according to manufacturing specifications and requirements. Preferably, the side heights of the second and third permeable modules 200 and 300 are the same.

[0052] In some embodiments, permeable concrete inherently possesses excellent permeability and a certain strength, effectively resisting water erosion. Three layers of aggregate of varying particle sizes are installed within the integrated piping rescue device. Sand-carrying water flows from bottom to top near the piping outlet, with the aggregate particle size preferably increasing gradually from 5 mm, 10 mm, and 15 mm along the infiltration direction. Because the water flow is turbulent and the Reynolds number exceeds the critical value before the piping is controlled, the traditional Darcy's law is inapplicable. Therefore, the permeability coefficient is selected as an indicator for measuring the permeability performance and quality control of the integrated piping rescue device, and its permeability coefficient is measured experimentally under constant head conditions.

[0053] The first permeable module 100 preferably uses coarse sand and gravel aggregate with a particle size of 5 mm, a thickness of 4 cm, and a pore size generally less than 5-10 mm. It can effectively intercept fine sediment particles and prevent them from being lost with the water flow. It is the main control layer for filtering water and retaining sediment in the integrated pipe burst rescue device. The permeability coefficient of the fine aggregate layer is determined by experiments to be approximately 16.5 mm / s.

[0054] The second permeable module 200 preferably uses crushed stone aggregate with a particle size of 1 cm and a thickness of 3 cm. It is a transition layer from the fine aggregate filter layer to the coarse aggregate drainage layer. The permeability coefficient of the fine aggregate layer is determined to be about 30 mm / s through experiments.

[0055] The third permeable module 300 preferably uses crushed stone aggregate with a particle size of 15 mm, a thickness of 3 cm, and a pore size generally less than 5 mm. As the coarse aggregate layer on the upper side, it can ensure the smooth discharge of water. The permeability coefficient of the fine aggregate layer is determined by experiments to be approximately 45 mm / s, while also enhancing the overall compressive strength of the module.

[0056] Combined with the permeability test results, the integrated piping rescue device of this embodiment controls the porosity and pore size by using three layers of aggregates with different particle sizes. The three layers are vertically distributed to form a series water filtration and sediment retention system. The vertical comprehensive permeability time and permeability coefficient of the integrated piping rescue device are:

[0057] T=h1 / K1+h2 / K2+h3 / K3=40 / 16.5+30 / 30+30 / 45=4.09s;

[0058] K=(h1+h2+h3) / T=100 / 4.09=24.45mm / s;

[0059] Where T represents the vertical integrated permeability duration, and K represents the permeability coefficient. h1 represents the lateral height of the first permeable module, h2 represents the lateral height of the second permeable module, and h3 represents the lateral height of the third permeable module. K1 represents the permeability coefficient of the first permeable module, K2 represents the permeability coefficient of the second permeable module, and K3 represents the permeability coefficient of the third permeable module. Since the actual permeability rate is also related to the material's porosity, particle size, and permeation pressure, it must be determined based on actual parameters.

[0060] In some embodiments, as Figure 1As shown, the bottom surface shape of the first permeable module 100, the second permeable module 200, and the third permeable module 300 is a regular hexagon. Specifically, when the integrated pipe burst rescue device needs to expand the rescue area by splicing, a regular hexagonal structural design is adopted to maximize the combination of densely paved splicing forms. According to the conditions of dense paving, the sum of the interior angles of a regular polygon must be divisible by 360°. Using mathematical principles, it can be proved that the hexagon is the largest regular polygon that can be densely paved. The interior angle of a regular hexagon is 120°, and the sum of the interior angles of three regular hexagons is exactly 360°. Therefore, the bottom surface shape of the integrated pipe burst rescue device is preferably a regular hexagon.

[0061] In some embodiments, when the integrated pipe burst rescue device is a regular hexagonal structure prefabricated with permeable concrete, each integrated pipe burst rescue device preferably has a side length of 30 cm, a thickness of 10 cm, and a volume of 23382.7 cubic centimeters (0.023 cubic meters). According to the average density of permeable concrete of about 800 kg / m 3 The weight of a single piece is about 18.7kg. This size design is convenient for transportation and handling, and can ensure sufficient strength and stability after splicing.

[0062] In some embodiments, the side of the second permeable module 200 is provided with a first tenon 210 and a first groove 220. The shapes of the first tenon 210 and the first groove 220 match each other and are spaced apart on the six sides of the second permeable module 200. Specifically, the first tenon 210 is a protruding block-like structure, and the first groove 220 is a concave groove-like structure. The two work together, and the matching shapes of the first tenon 210 and the first groove 220 ensure a secure connection between the components when engaged, enhancing the structural integrity and stability and preventing misalignment and slippage. Because the first permeable module 100, the second permeable module 200, and the third permeable module 300 are cylindrical with regular hexagonal bottom surfaces and are interconnected, the overall shape of the integrated piping rescue device is a regular hexagonal prism. The regular hexagonal prism includes two bottom surfaces and six side surfaces, each of which is a rectangle of equal area. The second permeable module 200 is provided with a first tenon 210 or a first groove 220 at the center of each rectangular side. The first tenon 210 and the first groove 220 are arranged separately on these six sides. That is, the first groove 220 is provided on both the left and right sides of the first tenon 210, and the first tenon 210 is provided on both the left and right sides of the first groove 220, for a total of three first grooves 220 and three first tenons 210. It can be understood that the function of the first tenon 210 and the first groove 220 is that when the bottom area of ​​a pipe burst rescue integrated device is not enough to cover the pipe burst outlet, multiple pipe burst rescue integrated devices can be spliced ​​together through the first tenon 210 and the first groove 220 to expand the bottom area, or when packaging the pipe burst rescue integrated device, it is necessary to separately splice the packaging structure with the first tenon 210 and the first groove 220 of the pipe burst rescue integrated device to protect the pipe burst rescue integrated device, so the shapes and sizes of the first tenon 210 and the first groove 220 must be able to match each other to achieve the purpose of connection and fixation.

[0063] In some embodiments, as Figure 2 As shown, the first tenon 210 and the first groove 220 respectively include two parallel straight edges and two oppositely positioned semicircular chamfers. Specifically, the semicircular chamfer design is to process the right-angled edge into a semicircular arc surface to reduce stress concentration, enhance the fatigue resistance of the structure, avoid scratches from sharp edges and improve safety, and optimize the appearance, texture and touch for smoothness, which is convenient for guiding alignment during assembly. The closed figure formed by two parallel straight edges and two semicircles connecting the two ends of the two straight edges is a combination figure of a semicircle with straight edges connected at both ends, similar to a "runway shape" or a "pillow shape". Using the combination figure of a semicircle with straight edges connected at both ends as the shape of the first tenon 210 and the first groove 220 is conducive to load-bearing positioning, reduces stress concentration, prevents scratches, and is convenient for assembly and docking, thereby improving the durability and safety of the structure.

[0064] In some embodiments, when each integrated piping rescue device has a side length of 30 cm, the height of the first tenon 210 and the first groove 220 is preferably 3 cm, the straight edge has a side length of 29 cm, and a semicircular chamfer with a diameter of 3 cm is used to facilitate automatic alignment during assembly. This connection structure allows multiple integrated piping rescue devices to be quickly and securely assembled together to form rescue structures of varying shapes and sizes to accommodate piping areas of varying sizes and shapes. The inlay of the first tenon 210 and the first groove 220 ensures a sealed joint.

[0065] In some embodiments, as Figure 3 and Figure 4 As shown. The integrated pipe burst rescue device can be used individually or in combination of multiple pieces, either spliced ​​or stacked, depending on the scale of the pipe burst. When the side of a single regular hexagon of the integrated pipe burst rescue device is 30 cm, it can achieve single-piece full coverage of small and larger pipe burst openings, where a small pipe burst opening is a pipe burst with a diameter of less than or equal to 5 cm, and a larger pipe burst opening is a pipe burst with a diameter of 15 cm. To be on the safe side, a circle of 6 single-piece integrated pipe burst rescue devices can be spliced ​​around the first tenon 210 and the first groove 220 to form a water filtration reverse osmosis body with a diameter of 90 cm. When the diameter of the pipe burst is large and the water head is high, and a layer of integrated pipe burst rescue device cannot completely prevent the large pipe burst, a double-layer or multi-layer integrated module can be used in a staggered and stacked manner.

[0066] In some embodiments, the third permeable module 300 is provided with a plurality of evenly distributed drainage holes. Specifically, the third permeable module 300 is provided with a plurality of evenly distributed drainage holes. These drainage holes are connected to the second permeable module 200, further improving the drainage efficiency of the device. When piping water flows strongly, they can serve as the primary drainage channel to quickly drain water, thereby reducing the hydraulic gradient at the piping hole opening and reducing the dynamic water pressure.

[0067] In some embodiments, when the side of a single regular hexagon in the integrated piping rescue device is 30 cm, the third permeable module 300 is evenly distributed with a plurality of drainage holes. The diameter of the drainage holes is preferably 0.8 cm, the spacing between the holes is preferably 5 cm, and the depth is consistent with the side height of the third permeable module 300. These drainage holes are connected to the second permeable module 200 within the integrated piping rescue device, further improving the drainage efficiency of the device. When the piping flow is large, they can serve as the main drainage channel to quickly drain water, reduce the hydraulic gradient at the piping orifice, and reduce the dynamic water pressure.

[0068] In some embodiments, a water ring is further included. The water ring is a hollow tubular structure with a port on one side seamlessly connected to the sides of the first, second, and third water permeable modules 100, 200, and 300. Specifically, the shape of the hollow tubular structure of the water ring is determined by the bottom shapes of the first, second, and third water permeable modules 100, 200, and 300. One side of the water ring completely encloses the sides of the first, second, and third water permeable modules 100, 200, and 300, with the bottom surface of the first and second water permeable modules 100, 200, and 300 serving as the bottom surface of one side of the water ring. The other side of the water ring has no bottom surface and is open. The height of the water ring is greater than the combined height of the sides of the first, second, and third water permeable modules 100, 200, and 300. When the bottom surface of the water ring in the integrated pipe burst rescue device with a water ring is placed at the outlet of the pipe burst for operation, the material of the water ring is not permeable. Since the port on one side of the water ring is seamlessly connected to the side of the first permeable module 100, the second permeable module 200, and the third permeable module 300, water cannot penetrate and discharge through the side wall of the water ring. The material of the water ring can be metal, thermoplastic plastic, thermosetting plastic, or other polymer material. Water that permeates through the first permeable module 100, the second permeable module 200, and the third permeable module 300 of the water ring is stored and stored, which can raise the water level to balance the internal and external head difference, reduce the hydraulic gradient, and suppress the outburst of groundwater carrying sediment, preventing the expansion of the pipe burst, and improving the efficiency of pipe burst rescue.

[0069] To achieve the above-mentioned purpose, on the other hand, an embodiment of the present application proposes a preparation method of an integrated pipe burst rescue device, the preparation method comprising: laying a geotextile on the bottom layer of a mold; pouring the porous material of the third permeable module 300 on the geotextile in the mold; when the porous material of the third permeable module 300 is in a stationary state, pouring the porous material of the second permeable module 200 on the porous material of the third permeable module 300; when the porous material of the second permeable module 200 is in a stationary state, pouring the porous material of the first permeable module 100 on the porous material of the second permeable module 200; vibrating and leveling the porous material after pouring; evaporating the moisture in the porous material by air drying or baking, and solidifying it, and obtaining the integrated pipe burst rescue device after demolding.

[0070] Specifically, in order to ensure the functional effect of each layer of the integrated piping rescue device, the preparation method of the integrated piping rescue device needs to follow the following technical points: customize the mold according to the shape of the integrated piping rescue device; adopt layered casting in the process of preparing the integrated piping rescue device; complete the production of the integrated piping rescue device through a one-time continuous casting and molding process to ensure that the bonding between the first permeable module 100, the second permeable module 200 and the third permeable module 300 is firm. It should be noted that when the integrated piping rescue device uses cast-in-place permeable concrete, in order to ensure uniform gaps and prevent cement slurry from accumulating under the action of gravity at the bottom of the module during the setting process and clogging the leakage channel, the water-cement ratio needs to be controlled preferably between 0.24 and 0.27. The bottom of the mold needs to be padded with a geotextile that can penetrate excess cement slurry to ensure that excess mud is smoothly discharged from the casting module. The method uses a reverse pouring process. More specifically, the third permeable module 300, with the largest aggregate particle size, is poured first. After reaching a predetermined thickness, the porous material of the second permeable module 200 is poured on top of the third permeable module 300, once the porous material of the third permeable module 300 has reached a stationary state. Finally, the porous material of the first permeable module 100 is poured after the porous material of the second permeable module 200 has reached a stationary state. This ensures that excess cement slurry does not clog the fine aggregate layer, maintaining a balanced interstitial space and unobstructed permeability channels. The poured first, second, and third permeable modules 100, 200, and 300 are then naturally air-dried or baked to evaporate the moisture in the porous materials and solidify them. Once the porous materials have achieved overall rigidity and strength, they are demolded to form an integrated pipe burst rescue device.

[0071] To achieve the above-mentioned purpose, the present application proposes a packaging method for an integrated pipe burst rescue device, such as Figure 5 As shown, Figure 5 The structure of an integrated pipe burst rescue device equipped with shock-absorbing buffer blocks is schematically illustrated. The packaging method includes: obtaining six shock-absorbing buffer blocks 400 based on the shape of the integrated pipe burst rescue device; fitting the right-angled surfaces of the shock-absorbing buffer blocks 400 to the side surfaces of the integrated pipe burst rescue device; and reinforcing the curved side surfaces of the fitted shock-absorbing buffer blocks 400 by wrapping ties around them. The cross-section of the shock-absorbing buffer blocks 400 is a minor arc, with the straight sides of the minor arc equal in length to the sides of a regular hexagon. The height of the shock-absorbing buffer blocks 400 is equal to the height of the side surfaces of the integrated pipe burst rescue device. The right-angled surfaces of the shock-absorbing buffer blocks 400 are provided with a second tenon or a second groove. The second tenon mates with the first groove 220, and the second groove mates with the first tenon 210. The shock-absorbing buffer blocks 400 and the integrated pipe burst rescue device are fitted together to form a cylinder.

[0072] Specifically, when the bottom surface of the integrated pipe burst rescue device is polygonal or irregular in shape, rolling transportation cannot be achieved, and the structure may have an obtuse outer edge angle that is easily damaged by external impact, affecting the dense paving effect of the structure. This embodiment proposes a packaging cushioning material design using a circumscribed circle. The material of the shock-absorbing buffer block 400 is a material that is elastic and can achieve a shock-absorbing effect, preferably a polyethylene high-density foam filling material, which can achieve the characteristics of light material, good impact resistance, pressure resistance, weathering resistance, easy molding, and low cost. The inscribed side of the shock-absorbing buffer block 400, that is, the right-angled plane, cooperates with the tongue and groove on the side of the integrated pipe burst rescue device. After packaging, the entire integrated pipe burst rescue device is a cylinder, which can be easily transported by hand or pushed after being stood on its side. It can adapt to uneven and complex terrain or narrow passages, and can be flexibly transported by rolling and flexibly avoid obstacles. The shock-absorbing buffer block 400 is reinforced with ties after packaging to prevent it from falling off due to vibration during movement. The ties include wrapping fabric or Velcro bandages to ensure that it does not fall off during rolling transportation and can be quickly disassembled and assembled after arrival. The ties can also be overlapped to achieve the function of bundling and fixing multiple pipe burst rescue integrated devices. In order to better protect the pipe burst rescue integrated device, the height of the shock-absorbing buffer block 400 can also be greater than the side height of the pipe burst rescue integrated device. When the packaged pipe burst rescue integrated device is stored in a warehouse for a long time waiting to be used, the bottom surface of the pipe burst rescue integrated device is stored facing the ground. Since the height of the shock-absorbing buffer block 400 is greater than the height of the side of the pipe burst rescue integrated device, the bottom surface of the pipe burst rescue integrated device will not directly contact the ground, preventing foreign matter or ground moisture from damaging the pipe burst rescue integrated device.

[0073] In some embodiments, as Figure 6 、 Figure 7 and Figure 8 As shown, when laying the integrated piping rescue device, ensure that the first permeable module 100 is placed on the bottom layer. When splicing multiple integrated piping rescue devices, ensure that the first tenons 210 and first grooves 220 of two adjacent modules face each other. To ensure proper installation and inspection and identification in emergency situations, color identification and text prompts are designed. Specifically, the bottom surface of the first permeable module 100 in contact with the piping is preferably painted dark green and printed with the words "This side down" in white font. The bottom surface of the third permeable module 300, which is not connected to the piping, is preferably painted red and printed with the large text "This side up" and the small text "Red top, green bottom, blue and yellow splicing." After installation, the red paint serves as a warning and danger warning for the bottom surface of the third permeable module 300 not connected to the second permeable module 200. The first tenon 210 is preferably painted blue with the words "Blue and yellow connect" printed on its side. The first groove 220 is preferably painted yellow with the words "Blue and yellow connect" printed on its side. The selection of colors and the text of the logo provide reminders and warnings to the integrated pipe burst rescue device during use. In this solution, there is no restriction on the specific colors and text logos.

[0074] In some embodiments, when performing pipe burst rescue, multiple pipe burst rescue integrated devices are spliced ​​together through the matching connection of the first tenon 210 and the first groove 220 according to the size and shape of the pipe burst area. First, the first pipe burst rescue integrated device is placed in the center of the pipe burst outlet so that the bottom surface of its first permeable module 100 is tightly fitted with the ground around the pipe burst outlet. Then, the other pipe burst rescue integrated devices are spliced ​​around the first pipe burst rescue integrated device in turn to form a larger coverage area, prevent the water and sand from the pipe burst from forming new outflow channels from the side, and ensure that the connection between the spliced ​​pipe burst rescue integrated devices is firm and reliable. In order to enhance the stability of the entire rescue structure, after the splicing is completed, the outer packaging straps can be connected to the outer edge of the structure and a counterweight can be set. The counterweight can be a concrete block or a sandbag, etc., connected to the hexagonal module by a rope or other fixing method.
