[0001] The present invention relates to the technical field of dam flood control and dam construction, and in particular to a dam breach blocking device and method. Background Art

[0002] During flood control, river dams may breach due to various reasons, causing serious economic losses to the country, society and the people, and even endangering people's lives. After the breach occurs, due to different conditions, the blocking methods used are also different. Generally, the breach is blocked by stacking sandbags from the top of the dam to the breach. However, due to the rapid flow of water at the breach, sandbags or heavy objects are easily washed away by the water.

[0003] When a dam breach occurs, currently, the common practice is to seal the breach on the dam bank. However, when the breach is large and the water flows very fast, it is difficult to seal it.

[0004] In reality, there are examples of using large trucks or ships to seal breaches. This method is not only costly, but also difficult to control when trucks and ships enter the breach, which may cause collisions with the dam and even cause the risk of secondary breaches. Summary of the invention

[0005] In view of the problems pointed out in the background technology, the present invention proposes a dam breach blocking device and method, which has low use cost and controllable blocking process.

[0013] The present invention is further configured that a water pump is provided on the floating plate, and the water pump can pump water into the balloon through the water inlet.

[0014] The present invention is further configured such that a limiting rope is provided inside the balloon.

[0015] A dam breach blocking method comprises the following steps: Step 1: Place the balloon into the water; Step 2, injecting water into the balloon; Step 3: Pull the water-filled balloon toward the breach site of the dam by pulling the ropes, pull two ropes on both sides of the breach site, and use a boat in the water to pull the two ropes respectively; Step 4: The balloon slowly approaches the breach in the dam and blocks the breach.

[0016] Step 5: Put the anchor into the water.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are as follows: The present invention provides a dam breach blocking device and method, which can block the dam breach by means of a water-filled balloon. The water-filled balloon can move in the water, and under the action of a pull rope, slowly moves toward the dam breach, gradually blocking the breach.
