Technical Field

[0001] The invention relates to an emergency flood control weir which can be stored on site and a rapid emergency flood control method, belonging to the technical field of water conservancy flood control emergency rescue. Background Art

[0002] In recent years, the climate has been complex and changeable, and extreme rainfall events have occurred frequently, making reservoir flood control pressure face more severe tests. Super-standard floods have caused small reservoirs to overflow and burst, causing huge losses of life and property, and becoming a shortcoming of the flood control engineering system. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses an emergency flood control weir and a rapid emergency flood control method that can be stored on site. The specific technical scheme is as follows: An emergency flood control weir that can be stored on site comprises a groove opened on the ground, wherein the length direction of the groove is to block the direction of flood flow, the groove comprises a plurality of rubber bag grooves, a connector groove is arranged between each two adjacent rubber bag grooves, the rubber bag grooves and the connector grooves are interconnected, a rubber bag is placed in each of the rubber bag grooves, and a connector is placed in each connector groove. When the rubber bag is inflated, the rubber bag part emerges from the rubber bag groove, and when all the rubber bags are inflated, the adjacent rubber bags squeeze the connectors from both sides at the same time to form a sealed flood control wall; when the rubber bag is deflated, the rubber bag retracts into the rubber bag groove, and when not in use, the connector is taken out of the connector groove, and a cover is placed on the surface of the groove to be flush with the ground.

[0004] Furthermore, the rubber bag is provided with an inflation valve.

[0005] Furthermore, the rubber bag comprises a large head portion of the rubber bag and a small head portion of the rubber bag, the large head portion of the rubber bag and the small head portion of the rubber bag are connected to each other, and after being inflated, each of them is spherical or elliptical, and the connecting portion is not higher than the groove, the small head portion of the rubber bag is located in the rubber bag groove, and the large head portion of the rubber bag is located above the rubber bag groove; The spherical radius / long diameter of the ellipsoidal sphere of the large head of the rubber bag is greater than the spherical radius / long diameter of the ellipsoidal sphere of the small head of the rubber bag; When the large head of the rubber bag and the small head of the rubber bag are both ellipsoidal, the direction of the long diameter is the horizontal direction.

[0006] Furthermore, the longitudinal section of the rubber bag groove in the width direction is in the shape of a spherical bottom and side portions open to both sides, and the longitudinal section of the rubber bag groove in the length direction is in the shape of a rectangle along the rubber bag groove.

[0007] Furthermore, the connector slot is in the shape of a rectangular space.

[0008] Furthermore, the connector is a rectangular bracket, which is surrounded by a waterproof sponge cloth and has tungsten mud placed inside.

[0009] Furthermore, in the width direction of the groove, the width of the connector groove is greater than the width of the rubber bag groove.

[0010] Furthermore, the cover on the top of the groove is made of a steel plate or cement board with holes, or a steel fence.

[0011] A flood control method based on the above-mentioned on-site accumulable emergency flood control weir comprises the following steps: Step 1: Dig a groove on the ground where water needs to be blocked and flood-proof. The groove is perpendicular to the direction of the incoming water to block the incoming water; The grooves are dug at intervals into the shape of the rubber bag groove and the connector groove; Step 2: Make multiple rubber bags, each with a separate inflation valve; Make a plurality of connectors, each of which is sealed with waterproof sponge cloth on all sides and the bottom, and is open on the top; Step 3: Place a rubber bag in each rubber bag slot; Step 4: When there is no need to block water and prevent floods, the rubber bag is in its original state and completely retracted into the rubber bag groove. A cover is placed on the top of the groove, and the ground is flat and does not affect ground traffic; Step 5: When it is necessary to prevent water and flood, open the cover on the top of the groove, put the empty connector into the connector groove, and then put tungsten mud into the connector, and inflate each rubber bag at the same time. After the rubber bag is fully filled with gas, the small head of the rubber bag is stuck inside the rubber bag groove, and the large head of the rubber bag is located above the rubber bag groove. The rubber bags on both sides of the connector squeeze towards the connector at the same time, and the connector deforms according to the shape of the rubber bag to seal the gap between the two rubber bags; Step 6: When the flood recedes, open the inflation valve of the rubber bag to deflate the air, and the rubber bag will shrink back into the rubber bag groove. Then take out the connector, pour out the tungsten mud inside and recycle it for next use. Finally, cover the top of the groove to restore the flatness of the ground.

[0012] Furthermore, when used for reservoir flood control, the groove is excavated on the side of the dam close to the reservoir, that is, the upstream side.

[0013] The beneficial effects of the present invention are: The present invention provides an emergency flood control weir that is simple to operate and can be quickly formed. It can be applied to emergency flood control sites such as small reservoirs, ponds, subways, garages or other communities. In rainstorm weather, it can quickly prevent floods and prevent the greatest property losses caused by floods. When the water level of a small reservoir is too high, the reservoir dam can be raised in time to prevent the reservoir from overflowing, providing technical support for flood control and rescue.

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] Combined with Figure 1-4 Specifically, the structure of the emergency flood weir that can be stored on site according to the present invention includes a groove 2 excavated on the ground, and the groove 2 includes a plurality of rubber bag grooves 3 and a connector groove 4, see Figure 1 A connector groove 4 is arranged between each two adjacent rubber bag grooves 3, and the width of the connector groove 4 is greater than the width of the rubber bag groove 3. The inner spaces of the rubber bag groove 3 and the connector groove 4 are interconnected.

[0021] A rubber bag 5 is placed in each rubber bag groove 3. The rubber bag 5 includes a large rubber bag head 51 and a small rubber bag head 52 that penetrate the inside. Each of the rubber bag 5 is spherical, and the connection is the intersection of the two spherical parts after overlapping. When flood prevention is used, a connector 6 is placed in each connector groove 4. When flood prevention is not used, the connector groove 4 is empty and no connector 6 is placed.

[0022] See also Figure 2 and 4 It can be seen that the longitudinal section of the rubber bag groove 3 in the width direction has a spherical bottom and side portions open to both sides in the width direction, and the longitudinal section of the rubber bag groove 3 in the length direction is a rectangle along the rubber bag groove 3 .

[0023] When the rubber bag 5 is inflated, the large head 51 of the rubber bag 5 pops out of the rubber bag groove 3, and the small head 52 of the rubber bag is stuck in the rubber bag groove 3. After all the rubber bags 5 are inflated, the adjacent rubber bags 5 squeeze the connector 6 from both sides at the same time to form a sealed flood wall; when the rubber bag 5 is deflated, the rubber bag 5 retracts into the rubber bag groove 3. When not in use, the connector 6 is taken out of the connector groove 4, and the surface of the groove 2 is covered with a cover flush with the ground.

[0024] The connector slot 4 is in the shape of a rectangular space. The connector 6 is a rectangular bracket, with a waterproof sponge cloth 7 enclosed around and at the bottom, and an open top, from which tungsten mud is filled toward the inside.

[0025] The cover on the top of the groove is made of a perforated steel plate or cement board, or a steel fence.

[0026] The following examples illustrate the embodiments of this patent: A reservoir is selected as the experimental area. Figure 1 As shown, a groove with the same length as the dam 1 is excavated on the upstream side of the reservoir dam 1. A plurality of rubber bags are made, each of which is 10m long and each of which has a separate inflation valve. A rubber bag is placed in each rubber bag slot 3 of the groove, and the rubber bags are connected with connectors. The specific dimensions of the groove are as follows: Figure 1 As shown in the figure, the width of the rubber bag groove 3 is 20 cm, and the width of the connector groove 4 is 70 cm and the length is 10 cm. Figure 2 The design shown is an ellipse with a longitudinal depth of 20 cm. The rubber bag is designed to be an inverted gourd. When the rubber bag is in a fully working state (fully filled with gas), the small head 52 of the rubber bag can be stuck inside the rubber bag groove 3 to fix the entire rubber bag. At this time, the height of the rubber bag above the dam surface is 50 cm and the width is 60 cm, which can block the water from the upstream of the dam. When the rubber bag is in a non-working state (original state), it can be retracted into the rubber bag groove 3, and a steel plate is laid on the top of the groove to ensure the flatness of the dam surface and not affect the normal operation of the dam.

[0027] In order to avoid a gap between the two rubber bags, which may cause water leakage or seepage, the present invention designs a connector such as Figure 3 As shown. First, a steel bracket with a length, width and height of 70cm, 10cm and 75cm is made, and then the bottom and four sides of the bracket are sealed with an elastic waterproof sponge cloth. When the present invention is needed to block floods, the tungsten mud with arbitrary shape, viscosity, non-toxicity, hydrophobicity and high density is filled into the entire steel bracket, that is, the inside of the connector, and then the steel bracket is placed in the connector slot 4. Since the tungsten mud can be formed into any shape, such as Figure 4As shown in the figure, when the rubber bags at the left and right ends of the connector are continuously inflated to reach a fully working state, the tungsten mud in the connector can form a shape that makes the two rubber bags fit tightly according to the shapes of the front and rear ends of the two rubber bags, so that the rubber bags are sealed and connected, thereby ensuring the complete sealing of the emergency flood control weir. When the flood recedes, the tungsten mud can be recycled, reducing the cost of the emergency flood control weir.

[0028] The process of the present invention is specifically as follows: First, a groove is excavated according to the shape and size of the groove, and a rubber bag of the shape and size is placed every 10 meters. When the water level of the reservoir is low, there is no need to use the rubber weir, the rubber bag is in its original state, and it is completely shrunk into the groove. A cover (steel plate) is laid on the top of the groove to ensure the flatness of the dam surface. When the water level of the reservoir is high and the rubber weir needs to be used to block water, the cover (steel plate) on the top of the groove is opened, the empty connector is placed in the connector slot 4, and then the tungsten mud is filled into the connector. Next, each rubber bag is inflated at the same time, so that the rubber bag can quickly reach a fully working state. At this point, an emergency flood control weir with simple operation, convenient assembly, rapid molding, and low cost can be completed, achieving the purpose of blocking the water from the upstream of the reservoir. When the flood recedes, the rubber bag inflation valve 53 is opened to deflate, and the rubber bag shrinks to the inside of the groove again, and then the connector is taken out, the tungsten mud inside it is poured out and recycled for next use, and finally the cover (steel plate) on the top of the groove is covered to restore the flatness of the dam surface.
