[0012] The specific steps to block the breach of the river embankment with the sandboxes are as follows:

[0013] Step 1: When the river embankment breaches in the early stage, stack and throw sandboxes on both sides of the breach in the riverbed. The sandboxes are hooked to each other through barbs. A large number of sandboxes are stacked on both sides of the breach to form a reinforcement matrix, and the reinforcement matrix prevents the breach from expanding further.

[0014] Step 2: After the reinforcement matrices on both sides are formed, continue to stack and throw sandboxes in the expected direction based on the reinforcement matrices. The sandboxes are hooked to each other through barbs to prevent the sandboxes from being washed away by the flood. Stack and throw sandboxes from the two sides of the reinforcement matrices in an arch direction to form an arch-shaped pre-intercepting dam, and the pre-intercepting dam reduces the water pressure and water flow of the flood.

[0015] Step 3: After the arch-shaped pre-intercepting dam is formed, the water pressure and water flow are reduced, and the breach is blocked with materials such as sand, stones, and soil.

[0016] Furthermore, during the construction of stacking and throwing sandboxes in the above solution, L-shaped partitions can be used to stack the sandboxes orderly in the carriage of the dump truck, which is convenient for transporting a large number of sandboxes quickly. Before stacking and throwing, the partitions are pulled out, and the sandboxes are thrown into the designated position at one time by the dump truck; alternatively, manual handling and throwing of sandboxes can be selected according to the on-site environment.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a sandbox for blocking the breach of a river embankment and a method for blocking the breach with this sandbox, having the following beneficial effects:

[0019] By filling the sandboxes with emergency materials such as stones, sand and gravel, and soil to increase the weight, and throwing the sandboxes into the breach, the sandboxes can be easily hooked to each other through barbs to prevent being washed away by the flood. After the reinforcement matrix is formed by stacking and throwing sandboxes on both sides of the breach, the reinforcement matrix can reduce the impact of the flood on the dam and prevent the breach from expanding further. The sandboxes are thrown and stacked to form a pre-intercepting dam, and the pre-intercepting dam can reduce the impact pressure of the flood and improve the success rate of blocking the breach.

[0033] A method for plugging a breach with a sand box includes the following steps:

[0034] Step 1, as Figure 3 shown,

[0035] After the river embankment breaches, sand boxes are stacked on both sides of the breach in the riverbed. The sand boxes are hooked to each other through barbs. A large number of sand boxes are stacked on both sides of the breach to form a reinforcement matrix. The sand boxes inside the reinforcement matrix are hooked to each other through barbs, with high anti-impact strength. The reinforcement matrix prevents the breach from continuing to expand.

[0036] Step 2, as Figure 4 shown,

[0037] After the reinforcement matrices on both sides are formed, sand boxes are continuously stacked towards the breach direction based on the reinforcement matrices. The sand boxes are hooked to each other through barbs to prevent the sand boxes from being washed away by the flood. Sand boxes are stacked from the two-sided reinforcement matrices in an arch direction to form an arch-shaped pre-interception dam. The sand boxes inside the pre-interception dam are hooked to each other through barbs, with high anti-impact strength. The pre-interception dam reduces the water pressure and water flow of the flood.

[0038] Step 3, as Figure 5 shown, after the arch-shaped pre-interception dam is formed, the breach is plugged with materials such as sand, stones, and soil.

[0039] In this embodiment, the sand boxes are stacked in an orderly manner in the dump truck compartment using the stacking positioning groove 6 and the partition 7, and a large number of sand boxes are transported quickly. Before placing, the partition 7 is pulled out, and the sand boxes are placed at the designated position at one time using the dump truck.
