Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, and relates to a device for rapidly constructing a flood-control sub-dike by using a water-filled rubber bag and an operating method thereof. Background Art

[0002] In the flood control and disaster relief in previous years, there are always moving scenes of rescue workers struggling to fill sandbags and wade through water to block pipe bursts. However, relying on the "hand-to-hand" flood control on shoulders and backs, building flood control sub-dikes requires a large number of people and materials. The built flood control sub-dikes must also be windproof and waveproof. After the flood, the sub-dikes must be cleaned up, which is time-consuming and labor-intensive. For example, in a certain place, more than 150 people were divided into 4 small teams and worked continuously for more than 30 hours to complete the construction of 1,200 meters of sub-dikes. The flood control sub-dikes were built with mud, sweat, and rain. For another example, during the 1998 flood, when the dikes were overflowing, the river water level rose rapidly, all exceeded the warning water level, and continued to rise. As the water level rose, the river water was likely to flow back and overflow the dikes, and the situation was very urgent. The time for dike construction was very tight, requiring a lot of manpower and material resources. Thousands of soldiers, armed with shovels, pickaxes and woven bags, soaked in the water, carried sandbags on their shoulders and backs, and built sub-embankments. They piled up 6 to 15 layers of sandbags, and used a layer-by-layer method to heighten and reinforce them. In order to prevent the river from eroding the newly built river embankment, plastic sheets were also used to block the water surface. Many people held shovels and desperately put soil into sandbags, shoveling one shovel after another, using their hands and feet from time to time. Their raincoats and rain boots were covered with mud, and they didn't even bother to wipe the sweat running down their cheeks. They fought bravely against the flood with their flesh and blood, and tried their best to protect the lives and property of the people.

[0003] In response to fierce floods, more and more high-tech flood-fighting "magic weapons" are being widely used in flood prevention and rescue. High-tech equipment is needed to enhance the hard power of flood prevention, and the continuous improvement of the scientific and technological content of flood prevention and flood control will take the efficiency and safety of flood prevention and flood control to a higher level. Strengthen the construction of comprehensive emergency rescue teams and the storage of emergency rescue materials with higher scientific and technological content. Flood prevention is needed every year, so it is urgent to improve the flood prevention and rescue ideas and seek solutions based on technological innovation. For the construction of flood control sub-dikes, time is tight and the workload is large, so it is necessary to explore new ideas that combine traditional engineering rescue measures with science. Summary of the invention

[0004] The invention provides a device and method for quickly constructing a flood-control sub-dike by using water-filled rubber bags, which is a low-carbon, environmentally friendly and energy-saving new flood control and rescue technology.

[0005] The present invention is achieved through the following technical solutions:

[0006] A device for quickly constructing a flood-control sub-dike is composed of a plurality of identical rubber bags, wherein the rubber bag comprises a bag body, the bag body comprises a bag surface and a bag bottom, the bag bottom comprises a bag body bottom and an extension section, the extension section extends from the bag body bottom, a water filling port is provided at the top of the bag surface, a drainage port is provided at the bag surface adjacent to the bag bottom, and a plurality of pile holes are provided on the extension section, the pile holes match the fixed piles.

[0007] Furthermore, the bag body is a variable cross-section structure in the longitudinal direction, one end of the variable cross-section structure is designed to be a positive L-shape, and the other end is designed to be a reverse L-shape. The two adjacent bag bodies are spliced ​​into one by docking the positive L-shape and the adjacent reverse L-shape. The positive L-shape and the adjacent reverse L-shape are split and overlapped with each other, which increases the seepage length of the bag body and the mutual bite. The two bag bodies are vertically butt-jointed, and the water pressure in the bag is pressed tightly against each other.

[0008] Furthermore, the positive L-shape on the bag body and the negative L-shape on the adjacent bag body are butted together to form a seam, and two tongues and grooves are formed at the seam perpendicular to the length direction of the bag body, respectively referred to as the right L-shaped tongue and groove and the left L-shaped tongue and groove. The width of the right L-shaped tongue and groove is smaller than that of the left L-shaped tongue and groove to ensure that the left L-shaped tongue and groove provides support for the right L-shaped tongue and groove on the water-facing surface. A sticking waterstop strip for water stopping is pasted at the seam of the right L-shaped tongue and groove on the water-facing surface.

[0009] Furthermore, the edges of the tongue and groove are respectively provided with rubber flanges. When two adjacent bag bodies are butt-jointed, the rubber flanges of the adjacent tongue and groove are butt-jointed together. The rubber flanges at the edges of the tongue and groove are provided with evenly distributed holes. Ropes are passed through the holes on the rubber flanges on both sides, cross-pierced and tied, so that the two adjacent bag bodies are tightly connected.

[0010] Furthermore, the bottom of the bag is made of hard rubber and soft rubber arranged alternately, similar to a folding fan, so as to be easy to fold and store. The width of the soft rubber is not less than 100 mm, the width of the hard rubber is 5 times the width of the soft rubber, the width of the extended section is not less than 0.5 m, the length of the bag body is 30 to 50 m, the width of the bag bottom is 1.5 to 1.8 times the water retaining height, and the cross-section of the bag surface is a semicircle made of flexible rubber.

[0011] Furthermore, a plurality of pile holes are evenly distributed on the extending section. The pile holes and the fixed piles have the same diameter and are used in combination. The fixed piles are made of wooden piles or round steel pipes. A rim reinforcement structure is provided around the pile holes to improve the anti-slip effect of the fixed piles.

[0012] Furthermore, the water filling port is arranged at the top of the bag surface for filling the bag body with water. An exhaust valve is provided at the top of the bag surface near the water filling port. The water filling port is a sleeve-like structure made of soft rubber. A check valve is embedded in the front end of the water filling port, and the check valve is connected to the water outlet pipe of a mobile water pump.

[0013] Furthermore, the drain port is arranged on the bag surface close to the bag bottom for draining water from the bag body. The drain port is a sleeve-like structure made of soft rubber. A control valve is provided in the middle of the drain port for controlling the discharge of water from the bag body.

[0014] Furthermore, the inner side of the extended section is connected to the bottom of the bag body, and the outer side of the extended section is connected to a slope protection cloth. A plurality of rings are provided at the outer edge of the slope protection cloth. A pressure rod is passed through the rings to press the slope protection cloth onto the slope surface of the embankment. The slope protection cloth is made of geotextile or colored strip cloth. The slope protection cloth, the extended section and the bag body have the same length. The pressure rod is made of PVC pipe, which is filled with sand and gravel, and cement is used to seal the holes at both ends of the PVC pipe.

[0015] An operating method of a device for quickly constructing a flood control sub-embankment using water-filled rubber bags comprises the following steps:

[0016] (1) A series of fixed piles are driven into the top of the embankment manually according to the number of bags required and the spacing between adjacent pile holes.

[0017] (2) Sequentially connect the pile holes on the bag body to the corresponding fixed piles.

[0018] (3) After the two adjacent bags are butt-jointed, the rope is first passed through the holes of the two bags, and then cross-pierced and tied to tightly connect the two bags.

[0019] (4) Paste the water stop strips at the seams of two adjacent bags on the water-facing side.

[0020] (5) Spread out the bag body and slope protection cloth,

[0021] (6) Insert the pressure rod into the ring on the slope protection cloth.

[0022] (7) Use a push rod to push the slope protection cloth into the water along the river bank slope.

[0023] (8) Use a mobile water pump to fill the bag with river water.

[0024] Technical principle of the present invention:

[0025] The rubber bag flood control sub-dike uses the principle of rubber dam, and uses multiple rubber bags connected and filled with water to form a flexible dam body, which plays a role in water blocking. The slope protection surface laid on the water-facing side can not only prevent wind and waves from eroding the levee, but also increase the anti-slip stability of the rubber bag. The rubber bag flood control sub-dike is mainly used as an emergency flood control product for embankments. This device breaks through the traditional thinking mode and abandons traditional embankment materials and processes. It is a new, fast, cheap, and environmentally friendly flood control and disaster reduction product. It has the characteristics of water blocking water, fast and convenient, and greatly improves the efficiency of disaster relief. Like building blocks, it is flexible to assemble and has strong adaptability; it is easy to store and transport, and has a low cost; it can be used multiple times and is green and environmentally friendly.

[0026] The rubber bags can be assembled on the top of the embankment, and a sub-embankment is formed after being filled with water. It is dozens of times faster than the traditional sandbag construction or assembly of embankments. Less materials are used, fewer people are required, and the labor intensity is low. The water-filled rubber bag is different from the traditional rubber dam. The former is a temporary building that requires easy construction and disassembly; the latter is a permanent hydraulic structure that requires a concrete foundation and needs to be installed. This device is a "magic weapon" with full scientific and technological content. In the face of fierce floods, it can be widely used in the front line of flood prevention and rescue. The former does not have a concrete bottom plate or anchoring, but uses the different hardness and shapes of the material to form the bag surface and bag bottom, and the tail dragged on the water surface - the slope protection cloth, forms a resistance, thereby achieving the stability of the bag body.

[0027] Beneficial effects of the present invention:

[0028] Water-filled rubber bags are used to build flood-control sub-dikes. Unfilled rubber bags have a small storage volume, are easy to transport, and can be assembled quickly. They can be used to block water in emergency situations. They can be recycled and reused after the flood, which is green and environmentally friendly. When raising the dam for flood control, a large amount of earthwork and manpower are no longer needed. Spread the assembled rubber bags on the top of the dam and connect the water-filling pump. A single rubber bag is about 50 meters long. In less than 3 to 5 minutes, a 50-meter-long and 1.5-meter-high sub-dike constructed by water-filled rubber bags is "built". Standardization, light weight, and simple components. The bag body, pressure rod, etc. are all standard components, which can be made in the factory, can be used universally, assembled on site, and have a small workload. It is particularly suitable for flood control and rescue as a flood-control sub-dike. When an ultra-standard flood occurs, the equipment is mainly used to temporarily increase the dam height. It uses water as the dam body filling material and can quickly build a flood-control sub-dike with any length. It takes 30 people 46 hours to build a 100-meter flood-control sub-dike with woven bags filled with soil. Constructing a flood-control sub-dike using water-filled rubber bags only requires 3 to 5 people and can be completed in 2 hours, without requiring a single bag of soil.

[0029] (1) The rubber bag is simple to arrange and easy to fill with water. It is quick to construct flood control sub-dikes and requires few personnel and materials. The bag can be recycled and reused, and there is no waste material. It will not cause environmental pollution. It is a low-carbon, environmentally friendly and ecologically conservation-oriented flood control technology.

[0030] (2) The bottom and surface of the rubber bag are integrated, and the bag is filled with water to form a water retaining dam, which can resist water with water; at the same time, the water in the bag provides a force for the bag body to retain water, and the filling of the bag body with water can serve two purposes.

[0031] (3) The device is integrated with the dike anti-scouring device, which can prevent flooding and dike scouring, thus ensuring the safety of the dike.

[0032] (4) The clever use of hard and soft rubber blocks not only solves the problem of the bag's anti-slip properties, but also makes it easy for the bag to be folded and rolled up, forming a water retaining dam after being filled with water.

[0033] (5) The individual bags are connected to each other, the seam design is reasonable, simple and easy to operate, with good anti-seepage effect, L-shaped tongue and groove, small front tongue and large back tongue and groove, ensuring the stability of the seam.

DETAILED DESCRIPTION

[0046] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method and a specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0047] like Figure 1 , 2 As shown, the device of the flood control sub-dike of the present invention is composed of a plurality of rubber bags 1, wherein the rubber bag 1 comprises a bag body, wherein the bag body comprises a bag surface 11 and a bag bottom 12, wherein the bag bottom 12 comprises a bag body bottom and an extending section 2, wherein the extending section 2 extends from the bag body bottom, a water filling port 111 is provided at the top of the bag surface 11, a drainage port 114 is provided at the bag surface 11 adjacent to the bag bottom 12, and a plurality of pile holes 21 are provided on the extending section 2, wherein the pile holes 21 match the fixed piles.

[0048] All components of a single rubber bag 1 are standard components, which can be made in the factory and can be used universally. The length of a single bag body can be one specification or several specifications, which can be determined according to the design requirements based on the storage warehouse, transportation equipment, etc. Other accessories are determined according to the number of bags. A single rubber bag 1 is made according to the following requirements: After the bag bottom 12 is cut into blocks, each block is welded into a plane; the rubber bottom extension section is cut, punched and sealed according to size, and welded to the bag bottom; the slope protection cloth 3 is cut, sewn with a ring, and welded to the extension section 2. After the bag surface 11 is expanded to the size according to the design requirements, it is welded to the bag bottom 12; the end of the split seam is cut, turned upside down, punched, and welded to the bag bottom and bag surface. The sleeve-shaped water filling port 111 and the drainage port 114 are made and welded to the bag body. The fixed pile and the pressure rod 4 are made according to the design size and the required quantity. The check valve 112 and the control valve 115 use existing products. After the various components are made, they are assembled into a single rubber bag 1. The individual rubber bags 1 are preferably spread out and laid flat on the shelf, and can be stacked in layers. Before use, the individual rubber bags 1 are manually rolled up one by one in the longitudinal direction, and then transported to the vehicle by a forklift, and transported to the levee site together with the supporting components, water pumps, etc.

[0049] like Figure 2-5As shown, the bag body is a variable cross-section structure in the longitudinal direction, one end of the variable cross-section structure is designed as a positive L-shape, and the other end is designed as an inverted L-shape. The positive L-shape and the adjacent inverted L-shape are connected to each other so that the two adjacent bags are connected and overlapped as a whole. The positive L-shape and the adjacent inverted L-shape seams overlap each other, which increases the seepage length of the bag body and also increases the mutual bite. The two bag bodies are connected vertically, and the water pressure in the bag is pressed tightly against each other. The positive L-shape on the bag body and the inverted L-shape of the adjacent bag body are connected to form a seam. The two openings perpendicular to the length direction of the bag body at the seam are respectively called the right L-shaped tongue and groove 13 and the left L-shaped tongue and groove 14. The width of the right L-shaped tongue and groove 13 is smaller than that of the left L-shaped tongue and groove 14 to ensure that the left L-shaped tongue and groove 14 at the back provides support for the right L-shaped tongue and groove 13 on the water-facing surface.

[0050] A water-stopping tape for water stopping is pasted at the seam of the right L-shaped tongue and groove 13 on the water-facing surface. The edges of the right L-shaped tongue and groove 13 and the left L-shaped tongue and groove 14 are respectively provided with rubber flanges. When two adjacent bag bodies are butted, the rubber flanges of the adjacent right L-shaped tongue and groove 13 and the left L-shaped tongue and groove 14 are butted together. The rubber flanges at the edges of the right L-shaped tongue and groove 13 and the left L-shaped tongue and groove 14 are evenly provided with holes. Ropes are passed through the holes on the rubber flanges on both sides, and the two adjacent bag bodies are tightly connected by cross-piercing and tying.

[0051] There are several pile holes 21 evenly distributed on the extension section 2. The diameter of the pile holes 21 and the fixed piles are the same and are used in combination. The fixed piles are wooden piles or round steel pipes. The surrounding of the pile holes 21 is provided with a rim reinforcement structure to improve the anti-slip effect of the fixed piles. The pile hole 21 is set at the extension section of the water-facing side of the bag bottom for not less than 0.5m. The pile hole and the extension section 2 are arranged in the middle. The hole diameter is consistent with the diameter of the fixed pile, generally 30 to 50mm. The pile hole spacing in the length direction is set as needed, generally 500 to 800mm. The pile body of the fixed pile is driven into the embankment soil for not less than 500mm and exposed on the top of the embankment for not less than 100mm. The fixed piles have positioning and anti-skid functions. The individual rubber bags 1 are standard parts and can be overlapped one by one and positioned by the fixed piles. The fixed piles also provide anti-skid force for the rubber bags under the action of water pressure. A is the bag bottom width, B is the extension section width, C is the slope protection cloth width, M is the right L-shaped tongue width, and N is the left L-shaped tongue width.

[0052] like Figure 6As shown, the bag bottom 12 is staggered by a hard rubber bottom 121 and a soft rubber bottom 122, similar to a folding fan, so as to facilitate folding and storage. The width of the soft rubber bottom 122 is not less than 100 mm, the width of the hard rubber bottom 121 is 5 times the width of the soft rubber, the width of the extension section 2 is not less than 0.5 m, the bag body length is 30 to 50 m, the width of the bag bottom 12 is 1.5 to 1.8 times the water retaining height, the cross-section of the bag surface 11 is a semicircle, and is made of flexible rubber. The bag surface 11 is made of chlorosulfonated polyethylene plus 50% natural rubber high-strength aging-resistant rubber coated fabric, the high-strength synthetic fiber fabric is used as a load-bearing skeleton, and rubber is coated inside and outside as a protective layer to be processed into a tape.

[0053] like Figure 7 , 8 As shown, Figure 8 The solid line in the middle represents the schematic diagram of the water-blocking state of the bag surface 11, and the dotted line represents the schematic diagram of the water-filled state of the bag surface 11. The weight of the water in the bag acts on the bottom of the bag. The hard rubber of the bag bottom 12 is not easy to deform. The water pressure of the bag surface 11 generates a pulling force on the bottom of the belt. The two bag surfaces 11 are connected at both ends of the bag bottom. The pulling forces generated are in opposite directions, roughly balanced, and basically symmetrical in shape. Under the action of external water pressure, under the action of the bag bottom 12 and the slope protection cloth 3, after the rubber bag is filled with water, the bag surface 11 generates radial pulling force under the action of the water pressure in the bag. The structural calculation of the rubber bag adopts the plane problem assumption and is calculated according to the thin film theory. The specific calculation formula is as follows:

[0054]

[0055] Where: T——radial calculated strength of bag, kN / m;

[0056] γ——Specific gravity of water, kN / m 3 ;

[0057] α——internal pressure ratio, H0 / H1;

[0058] H0——internal pressure head, m;

[0059] H1——Design bag height, m.

[0060] The main design loads acting on the bag body are the hydrostatic pressure outside the bag body and the water filling pressure inside the bag body. Generally, the internal pressure ratio of a water-filled rubber bag should be α = 1.25 ~ 1.60.

[0061] When the water-filled rubber bag is used as a flood-proof sub-embankment and blocks water, the main calculation is anti-slip stability under the action of water pressure. The water weight inside and outside the bag increases the friction at the bottom of the bag, and the outer extension and slope protection cloth also provide friction. The sum of the friction of the three sections and the horizontal thrust generated by the bag body after blocking water constitute a balance of horizontal force.

[0062]

[0063] Where: Kc——anti-sliding stability safety factor, generally the safety factor should be greater than 1.0;

[0064] ∑G——all vertical loads acting on the bottom of the rubber bag (including the uplift pressure on the bottom surface of the bag, kN);

[0065] ∑H——Total horizontal load acting on the bottom of the rubber bag (kN);

[0066] f is the friction coefficient between the bottom of the rubber bag and the top of the embankment, which can generally be taken as 0.25 to 0.35 based on medium-hard clay soil.

[0067] like Fig. 9 As shown, the inner side of the overhanging section 2 is connected to the bottom of the bag body, and the outer side of the overhanging section 2 is connected to a slope protection cloth 3. A plurality of rings 31 are provided at the outer edge of the slope protection cloth 3. A pressure rod 4 is used to pass through the rings 31 to fix the slope protection cloth 3 on the river bank. The slope protection cloth 3 is made of geotextile or color strip cloth. The slope protection cloth 3, the overhanging section 2 and the bag body have the same length. The pressure rod 4 is made of PVC pipe, and the PVC pipe is filled with sand and gravel, and the holes at both ends are sealed with cement. The diameter of the PVC pipe can be φ50~φ100, and the length is preferably 2~3m.

[0068] The slope protection cloth 3 is a long strip, which is equal to the length of the bag body and has a width of 1.0-1.5m. One end in the width direction is connected to the bag bottom 2. A pressure rod 4 is preferably 2.0-3.0m long, and at least three rings 31 are provided to facilitate the fixation of the pressure rod 4. The slope protection cloth 3 is a geotextile or a color strip cloth. It is the same length as a single rubber bag 1, and the length along the slope (the width of the cloth) is not less than 2.0m.

[0069] According to the designed spacing and position, the fixed piles are driven in manually, and then the pile holes 21 on the bag body are sleeved on the positioning piles, and then the bag body and the slope protection cloth 3 are spread out. The slope protection cloth 3 on the water-facing side is put in place at the top of the slope, and the pressure rod 4 is passed through the ring 31 at the end of the slope protection cloth 3, and tied with ropes. When the slope protection cloth 3 needs to be extended into the water on the slope, a push rod (similar to a clothes drying rod) is used to manually push the pressure rod to drive the slope protection cloth 3 and push it down along the embankment slope. After the slope protection cloth 3 is put through the pressure rod 4, it is put into the slope, and then the push rod is used to push it into place along the slope. It is simple and easy to operate, and it avoids personnel operating in the water. It improves the manual laying of anti-scouring slope protection during the flood season, improves efficiency, and reduces the risk of manual operation. Under the action of water pressure, the slope protection cloth 3 is tightly attached to the slope, which can not only prevent waves from scouring the embankment, but also provide a pulling force to the rubber bag, that is, increase the anti-slip force of the rubber bag, and it is a two-in-one.

[0070] like Fig.10As shown, a water filling port 111 is provided at the top of the bag surface 11 for filling the bag with water. An exhaust valve 113 is provided near the water filling port 111 at the top of the bag surface 11. The water filling port 111 is a sleeve-shaped structure made of soft rubber. A check valve is embedded in the front end of the water filling port 111. The check valve 112 is connected to the outlet pipe of a mobile water pump. When filling with water, the outlet pipe of the mobile water pump is inserted into the interface in front of the check valve 112, and the mobile water pump is started to fill with water. After the water filling is completed, the check valve 112 controls the water flow to prevent overflow. In addition, 1 to 2 mobile water pumps are equipped.

[0071] like Fig.11 As shown, a drain port 114 is provided on the bag surface 11 adjacent to the bag bottom 12 for draining water from the bag. The drain port 114 is a sleeve-shaped structure made of soft rubber. A control valve 115 is provided in the middle of the drain port 114 for controlling the discharge of water from the bag. When drainage is required, the control valve 115 is opened to drain water to one side of the river until it is emptied, and then the control valve 115 is closed.

[0072] The present invention proposes a new technology for quickly constructing flood-control sub-dikes, which is to construct flood-control sub-dikes with water-filled rubber bags, a low-carbon, environmentally friendly and eco-friendly flood control technology. It is fast and convenient, can be recycled for secondary use, does not require earthwork cleaning, and has a small workload. The flood-control sub-dike is formed by overlapping individual rubber bags to form a dam body, and a slope protection cloth is set on the water-facing surface. A single rubber bag consists of four parts: a bag body and small accessories (connecting ropes and holes, adhesive water stop strips), a water filling port and a drainage port, a slope protection cloth and pile holes, fixed piles and pressure rods. Each component is a standard component, which is convenient for factory production and easy to use. After the rubber bag on the top of the embankment is filled with water, it can prevent floods from overflowing the top, and the slope protection cloth on the water-facing surface can prevent waves from scouring the embankment. The rubber bag can both block water and protect slopes, and one bag has two uses in one.

[0073] The water-filled rubber bags can be assembled and disassembled quickly. The bags are light and can be transported to the top of the dike where the sub-dike is needed by vehicles or manual labor. They are laid manually, which greatly improves the efficiency of dike construction. The previous "hand-to-hand" flood control that relied on human shoulders and backs has been changed. High technology is redefining flood control and rescue in the new era. The rubber bag is a flexible dam body after being filled with water, and the original dike is also a flexible body. The two are highly coordinated with each other.

[0074] The rubber bag flood control sub-dike breaks through the traditional thinking mode and abandons the traditional materials and processes of dike construction. It is a new, fast, cheap and environmentally friendly disaster prevention and mitigation equipment. It has the characteristics of fast assembly, flexible dam grouping, strong adaptability, easy storage and transportation, low cost, recycling and reuse, green and environmental protection. Water is used to block water and water is used to control water, with novel ideas. The bag body is simple in layout, easy to fill with water, and the construction of flood control sub-dike is fast. It requires few people and materials. The bag body can be recycled and reused, there is no waste material, and it will not cause environmental pollution. It is a low-carbon, environmentally friendly and ecological conservation flood control technology. Flood control materials can be used as spare parts, stored in warehouses, and uniformly allocated when needed. The assembly process is adopted, like building blocks. After the various components are processed in the factory, they are stored in the flood control material warehouse and transported to the site for assembly when needed. Flood control every year, flood control materials are indispensable, and rubber bags can be stored in advance to be prepared for any eventuality. They have broad application prospects throughout the country.

[0075] An operating method for quickly constructing a flood prevention sub-dike device using water-filled rubber bags comprises the following steps:

[0076] (1) A series of fixed piles are manually driven into the top 5 of the embankment according to the number of bags required and the spacing between adjacent pile holes.

[0077] (2) All the pile holes 21 on the bag bodies are connected to the corresponding fixed piles.

[0078] (3) After the two adjacent bags are butt-jointed, the rope is first passed through the holes of the two bags, and then cross-pierced and tied to tightly connect the two bags.

[0079] (4) Paste the water stop strips at the seams of two adjacent bags on the water-facing side.

[0080] (5) Spread out the bag body and slope protection cloth 3,

[0081] (6) Insert the pressure rod 4 into the ring 31 on the slope protection cloth 3,

[0082] (7) Use a push rod to push the slope protection cloth 3 into the water along the river bank slope.

[0083] (8) Use a mobile water pump to fill the bag with river water.

[0084] The length of the temporary flood control sub-dike is calculated and determined according to the needs, and the number of individual rubber bags is loaded and transported to the site. The rubber bag flood control sub-dike does not require any damage to the original embankment top. Rubber bags can be laid on earthen embankment tops, concrete embankments, or asphalt embankment tops. The construction adopts an assembly process, like building blocks. After the various components are processed in the factory, they are stored in the flood control material warehouse and transported to the site for assembly when needed. Also pay attention to the following points:

[0085] (1) Before laying the bag body, the earthen embankment top should be properly leveled and sharp objects and weeds should be removed; when the embankment top is a soft material surface layer such as concrete or asphalt, before laying the bag body, after cleaning the surface dirt, a layer of silt should be laid first to increase the bond between the bag body and the concrete surface to ensure the anti-seepage effect. And according to the spacing and position of the pile holes, holes should be drilled in the hard surface layer to facilitate the construction of fixed piles. The distance between the foot of the water-filled rubber bag facing the water and the shoulder of the embankment on the water side should not be less than 0.5m, and the slope protection cloth should be used for about 2.0m along the embankment slope. This range should be cleaned up.

[0086] (2) Fixed pile sinking: Use ropes to lay out lines and drive wooden piles or precast concrete piles according to the designed pile spacing.

[0087] (3) Connect the pile hole on the extended section of a single rubber bag to the fixed pile. Then unfold the rubber bag. At the same time, lay the slope protection cloth and arrange the pressure rods.

[0088] (4) Install the second rubber bag as described in (3) and tie the two bag surfaces together at the seam. Install the third rubber bag in the same way, and the fourth...

[0089] (5) The rubber bags required for the flood-control sub-dike have been installed. The rubber bags at one end of the sub-dike are filled with water, and then filled with water in the longitudinal direction. After the filling is completed, the water-stop rubber belt is attached to the water-facing surface of the joint, including the extended section of the rubber bottom. At this point, the flood-control sub-dike is completed by filling the rubber bags with water.

[0090] (6) After the flood prevention task is completed, open the drain, drain all the water from the bag, and clean the dirt on the bag; first take out the slope protection cloth pressure rod, detach the fixing pile of the extended section, and fold the slope protection cloth and the extended section together on the bag surface; roll up the bag longitudinally from one end of the rubber bag, and transport it to the car by forklift; after transporting it to the warehouse, clean it again, and after it meets the storage conditions, unfold it and place it flat on the shelf.
