Description

Technical Field

[0001] This invention belongs to the field of water conservancy and flood control technology, specifically relating to a method for sealing breaches in small and medium-sized dikes. Background Technology

[0002] With my country's economic development, the country's flood control engineering system has achieved a series of significant accomplishments after years of construction, with a marked reduction in dam breaches and a substantial improvement in flood control capabilities. The flood control engineering system of dams is an important research area in my country.

[0003] During the emergency rescue operation, the inability of large machinery to access the site resulted in a significant expenditure of manpower and resources. When sealing the breach, gabions filled with stones were pushed into the breach. However, large excavators and bulldozers could not reach the disaster relief site, forcing a large number of People's Liberation Army soldiers to work together to push the gabions into the breach. This method presented several problems: firstly, manual pushing was insufficient, requiring the concerted effort of many people; secondly, the safety factor of small and medium-sized dams is not high, requiring the gabions to be very close to the breach to achieve the desired effect, but this posed a significant threat to the lives of those pushing the gabions, as a secondary breach could occur at any time. This method of pushing gabions into the breach was inefficient and risky, making it unsuitable for widespread application. Therefore, there is an urgent need to develop a new method and pushing device suitable for emergency rescue of small and medium-sized dam breaches. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a method for sealing breaches in small and medium-sized dikes that is easy to operate, reduces the intensity of manual labor, and is safe and reliable.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a method for sealing breaches in small and medium-sized dikes, comprising the following steps:

[0006] (1) Place several parallel support rails on the back side of the breach in the dam. The length of the support rails is arranged along the front-to-back direction, and the front end of the support rails extends to the breach.

[0007] (2) Place gabion mesh on the upper part of the rear end of the support rail;

[0008] (3) Place stones into the gabion net;

[0009] (4) Assemble the pushing device on the bottom surface of the back side of the gabion mesh;

[0010] (5) Operate the pushing device to push the gabion net filled with stones forward until the gabion net moves to the breach and blocks the breach.

[0011] The support rails in step (1) are made of steel pipe, channel steel, angle steel or I-beam.

[0012] The pushing device in step (4) includes a support plate, a bracket, a jack, and at least two long strip bases. The long strip bases, the jack, and the support rail are aligned in length. All the long strip bases are connected as one unit by several connecting rods. The connecting rods are perpendicular to the long strip bases. The top surface of the long strip bases is provided with several slots spaced along the length direction. There is one support plate. The lower end of the support plate is inserted into the slot on the rear side of the long strip base. There are two brackets. The two brackets are spaced apart front and back. The lower ends of the two brackets are both located on the long strip bases. The rear bracket is located on the front side of the support plate. The jack is located on the two brackets.

[0013] A diagonal brace is provided on the rear side of the support plate, and the lower end of the diagonal brace is inserted into a slot on the long strip base on the rear side of the support plate.

[0014] The support includes a circular ring and two symmetrical diagonal braces. The lower ends of the two diagonal braces are fixed with slotted plates that are locked onto a long strip base. The upper ends of the two diagonal braces are fixedly connected to the outer circle of the circular ring. The jack is inserted into the circular ring along the front-back direction.

[0015] The elongated base has three sections. The middle elongated base has several through holes that are open to the left and right. The left elongated base has a left blind hole with the same number of through holes and corresponding to the left and right sides. The left elongated base also has a right blind hole with the same number of through holes and corresponding to the left and right sides. The right side of the left blind hole is open, and the left side of the right blind hole is open. The connecting rod passes through the through holes, with the left end of the connecting rod inserted into the left blind hole and the right end of the connecting rod inserted into the right blind hole.

[0016] The rear end of the jack cylinder is equipped with a rear pressure plate that cooperates with the support plate to press down, and the front end of the jack telescopic rod is equipped with a front pressure plate that presses down on the gabion mesh.

[0017] The lower surface of the long, rectangular base is provided with several spikes spaced apart along its length.

[0018] The specific process of step (4) is as follows: First, lay the middle long strip base on the ground. Insert the connecting rod into all the holes of the long strip base. Then, place the left long strip base on the left end of the connecting rod and insert the left end of all the connecting rods into the left blind hole of the left long strip base. Place the right long strip base on the right end of the connecting rod and insert the right end of all the connecting rods into the right blind hole of the right long strip base. Then, clamp the slotted plates at the bottom of the two brackets onto the left and right long strip bases respectively. Then, insert the jack into the ring at the top of the bracket. Finally, insert the support plate and the lower end of the diagonal brace into the two adjacent sets of slots.

[0019] The specific process of step (5) is as follows: start the jack, extend the telescopic rod of the jack, push the gabion mesh with the front pressure plate, press the support plate with the rear pressure plate, and insert the ground spikes into the ground to keep the entire pushing device in position. As the telescopic rod gradually extends, slide the gabion mesh forward along the support guide rail until the gabion mesh slides to the breach and gets off the support guide rail. Move the support guide rail away, and keep the jack pressing the length of the gabion mesh. In this way, the gabion mesh is positioned and sealed at the breach of the dam.

[0020] By adopting the above technical solution, the present invention has the following beneficial effects:

[0021] 1. The long, narrow base, connecting rod, bracket, and support plate are designed to be modular, making them easy for people to carry and assemble on-site during rescue operations. The long, narrow base is fitted with spikes similar to a rake by welding or riveting. The spikes embed themselves into the ground under the weight of the entire pushing device, forming a single unit with the ground. This provides sufficient grip for the jack to deliver horizontal thrust, preventing the entire pushing device from tipping over or sliding.

[0022] 2. Based on the weight of the stones in the gabion mesh, the jacks are roughly calculated and supports of different heights are selected to ensure that the center of the jacks and the sides of the gabion mesh are on the same horizontal line, so as to better exert the function of the jacks. The grooved plates at the lower ends of the two diagonal braces of the support hold the long strip base, which serves to position the jacks in the left and right directions.

[0023] 3. During operation, the jack generates a thrust at its front end, which in turn generates an equal reaction force at its rear end. The support plate at the rear end is designed to absorb this reaction force. A diagonal brace is installed at the rear of the support plate to provide good support and ensure its stability.

[0024] 4. Because the front end of the telescopic rod of the jack used to exert force is a relatively small circular plane, if the front end of the jack is used directly to exert force when pushing the gabion mesh, the small force-bearing area may break the gabion mesh, and the gabion mesh will lose its original function. The purpose of adding the jack cap is to add a front pressure plate at the front end of the jack to increase its force-bearing area and ensure that the structure of the gabion mesh will not be damaged when pushing it.

[0025] 5. Multiple long strip bases are provided for easy handling and carrying. Connecting rods connect the multiple long strip bases into one unit, which is convenient for insertion and disassembly. This ensures relative movement when the gabion mesh is pushed, and ensures the integrity and stability of the multiple long strip bases.

[0026] 6. The top of the long strip base is equipped with several slots, which makes it easy to insert the support plate and diagonal brace into different slots to adjust the position of the gabion mesh and the distance of one-time advance.

[0027] 7. Place several parallel support rails on the back side of the dam breach. When the gabion mesh is pushed, the bottom of the gabion mesh slides on the support rails, reducing friction, improving efficiency and reducing energy consumption.

[0028] 8. The jack can be connected to a hydraulic station via an oil pipe. The hydraulic station is placed on multiple long strip bases. The extension and retraction of the jack can be controlled remotely. The extension and retraction function of the jack can be realized by pressing a button, avoiding close-range operation and ensuring the safety of personnel to the greatest extent possible.

[0029] In summary, this invention is based on scientific principles, has a reasonable design, and a simple structure. It is easy to assemble, solves the problem of the difficulty in sealing breaches in dikes, reduces the intensity of manual labor, and has high safety. After sealing, the gabion mesh has strong stability and good results. Attached Figure Description
