Description

Technical Field

[0001] The invention belongs to the field of water conservancy projects, and in particular relates to a method for quickly sealing a dam breach. Background Art

[0002] Sealing dam breaches is a common problem faced during flood control and emergency response. During floods, dams along rivers, lakes, and reservoirs often breach. Rapidly sealing these breaches can significantly reduce losses and save lives and property. Currently, the most common method for addressing dam breaches is to place sandbags and rocks at the breach, install steel pipe gratings, and create temporary barriers. However, these breaches are often washed away by the overwhelming force of the water flow. Even dump trucks and ships that have been forced into the water without effective means of securing them can be swept away. Consequently, a rapid and effective method for sealing breaches remains unavailable. Summary of the Invention

[0003] In order to overcome the deficiencies and problems of the prior art, the present invention provides a method for quickly sealing a dam breach to reduce flood losses.

[0004] The present invention is achieved through the following technical solutions:

[0005] A method for quickly sealing a dam breach comprises the following steps:

[0006] S01. Rotate the bow of hull one and secure it to one side of the embankment breach, and rotate the bow of hull two and secure it to the other side of the embankment breach. Rotate hulls one and two toward the embankment breach until their sterns touch, then connect and secure the touched sterns. Hulls one and two now form a V-shape.

[0007] S02. Insert a row of support rods on both sides of hull one and hull two. Insert the support rods vertically downward from the sides of hull one and hull two into the riverbed and hammer them in to reinforce them. The rods of the support rods are fixed to hull one or hull two.

[0008] S03. On the side of Hull 1 and Hull 2 ​​facing away from the dam breach, sandbags are thrown into the water to form a sandbag isolation wall. While slowing down the water flow at the breach, sandbags are piled on the side of Hull 1 and Hull 2 ​​facing the dam breach until a temporary dam is formed to seal the breach.

[0009] In step S02, anti-scouring cloths are laid on both sides of the dam breach, extending to the bottom of both sides of the dam breach, and the two anti-scouring cloths are fixed to the support rods of the first hull and the second hull respectively with ropes.

[0010] In step S02, when the support rod is subjected to excessive impact force from the water flow during insertion into the riverbed, a traction boat is used to pull the support rod with a rope to offset or reduce the impact force of the water flow on the support rod.

[0011] The hull one and the hull two are both in the shape of long strips. Both sides of the hull one and the hull two are provided with a plurality of vertically arranged sleeves, which match the support rods. The support rods pass through the sleeves and are inserted into the riverbed.

[0012] When the hull 1 and the hull 2 ​​are in use, the sleeves on the side facing the impact of the water flow are arranged more densely than the sleeves on the other side.

[0013] The sleeves are arranged in groups of two, and the two sleeves in the same group are coaxially arranged up and down.

[0014] A locking component for fixing the support rod is provided between the two sleeves of each group.

[0015] The hull one and the hull two are both steel structure hulls, and the hulls of the hull one and the hull two are provided with transversely and obliquely arranged reinforcing ribs.

[0016] The connected ends of the hull one and the hull two are both provided with an inclined surface, and the two inclined surfaces match so that the hull one and the hull two are V-shaped, and buffer rubber pads are provided on the two inclined surfaces.

[0017] The traction boat is provided with a cable winding wheel device, a transition wheel is provided on the side of the traction boat, a guide rod is provided on the side of the traction boat which is obliquely inserted into the riverbed, a traction wheel is provided at the bottom of the guide rod, and the cable winding wheel device is wound with a cable, and the cable passes through the transition wheel and the traction wheel in sequence and is connected to the guide rod.

[0018] In the present invention, hull one and hull two are connected in a V shape, which has a stable structure and can effectively disperse the impact force of the water flow to prevent hull one and hull two from being washed away by the water flow; support rods are inserted on both sides of hull one and hull two, which can block and fix the sandbags after the sandbags are thrown in, preventing the sandbags from being washed away by the water flow, thereby effectively building a sandbag isolation wall to block the water flow, and then completing the sealing of the dam breach.

DETAILED DESCRIPTION

[0024] To facilitate understanding by those skilled in the art, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, a method for quickly sealing a dam breach comprises the following steps:

[0026] S01, rotate and fix the bow of hull 1 to one side of the dam breach 3, rotate and fix the bow of hull 2 ​​to the other side of the dam breach 3, and combine Figure 2 As shown, the bows of hulls 1 and 2 are each equipped with a pull ring 100. The bows of hulls 1 and 2 are respectively placed against the dike 4 on either side of the dike breach. Fixing piles 200 are driven through the pull rings 100 and driven into the dike 4, thereby allowing hulls 1 and 2 to be rotated and fixed to either side of the dike breach 3. Reinforcement piles can also be driven into the dike, securing the reinforcement piles to the fixing piles 200. Hulls 1 and 2 are rotated toward the dike breach until their sterns abut. The abutted sterns are then connected and fixed. The sterns of hulls 1 and 2 are each equipped with a fixing ring 300. These fixing rings 300 can be secured to each other via a lock or connecting shaft. Hulls 1 and 2 now form a V-shape, providing a stable structure that effectively disperses the impact of water flow and prevents hulls 1 and 2 from being swept away. The sterns of both hull 1 and hull 2 ​​are provided with inclined surfaces 400, which match to form a V-shape. Cushion pads 401 are provided on both inclined surfaces 400 to prevent hard collisions when hull 1 and hull 2 ​​are in contact.

[0027] S02. Insert a row of support rods 500 on both sides of hull 1 and hull 2. Insert the support rods 500 vertically downward from the sides of hull 1 and hull 2 ​​into the riverbed and hammer them for reinforcement. The rods of the support rods 500 are fixed to hull 1 or hull 2. When the water level becomes low, the support rods 500 can support hull 1 and hull 2. Both hull 1 and hull 2 ​​are long strips. Figure 3As shown, both sides of hull 1 and hull 2 ​​are equipped with multiple vertically arranged sleeves 600. The sleeves 600 match the support rods 500, and the support rods 500 are inserted into the riverbed after passing through the sleeves 600. The sleeves 600 are arranged in groups of two, and the two sleeves 600 in the same group are arranged coaxially. A locking member 610 is provided between the two sleeves 600 in each group to secure the support rods 500. After the support rods 500 are inserted into the riverbed, the locking member 610 can be used to lock the support rods 500, which is convenient and quick. The locking member 610 adopts an existing clamp, pipe clamp, or other structural component that can lock the support rods 500.

[0028] Combine Figure 4 As shown, when the support rod 500 is subjected to excessive impact from the water flow during insertion into the riverbed, a tugboat 5 is used to pull the support rod 500 with a cable 51 to offset or reduce the impact of the water flow on the support rod 500. This makes it easier to insert the support rod 500 into the riverbed, especially when there is a large water level difference on both sides of the support rod 500, the flow rate is fast, and the impact on the support rod 500 is large. The tugboat 5 is equipped with a cable reel device 52, a transition wheel 53 is provided on the side of the tugboat 5, and a guide rod 54 is provided on the side of the tugboat 5 that can rotate and be inserted obliquely underwater. The bottom of the guide rod 54 is provided with a traction wheel 55. The cable reel device 52 is wound with a cable 51, which passes through the transition wheel 52 and the traction wheel 55 in sequence before being connected to the support rod 500. This structure prevents the guide rod 54 from being separated from the riverbed when pulled by the cable 51.

[0029] In step S02, anti-scouring cloth 501 is laid on both sides of the dam breach. The anti-scouring cloth 501 extends to the bottom of both sides of the dam breach. The two anti-scouring cloths 501 are respectively fixed to the support rods of hull 1 and hull 2 ​​with ropes. The anti-scouring cloth 501 covers the side of the dam breach 3, reducing the water flow from eroding the dam and delaying further expansion of the breach.

[0030] S03. On the side of Hull 1 and Hull 2 ​​facing away from the dam breach, sandbags are thrown into the water to form a sandbag isolation wall. While the water flow in the breach is slowed down, sandbags are piled on the side of Hull 1 and Hull 2 ​​facing the dam breach until a temporary dam is formed to seal the breach.

[0031] Preferably, when hull 1 and hull 2 ​​are in use, the sleeves 600 on the side facing the impact of the water flow are arranged more densely than the sleeves 600 on the other side, that is, more support rods 500 are arranged on the side facing the impact of the water flow to block the sandbags.

[0032] Preferably, hull 1 and hull 2 ​​are both steel structure hulls, and the hulls of hull 1 and hull 2 ​​are provided with transversely and obliquely arranged reinforcing ribs 700, which can strengthen the hull structure and make the hull stronger.

[0033] The above embodiments are preferred implementations of the present invention and are not intended to limit the present invention. Without departing from the inventive concept of the present invention, any obvious replacements are within the scope of protection of the present invention.
