Further, the water-filled bag 101 is made of hemp rope or wool rope, and the counterweight 103 is made of iron scale, sand bag, soil bag or concrete block.

In the method for blocking the breach, the water-filled mesh bag assembly can be thrown to the breach, wherein the method for throwing the water-filled mesh bag assembly into the breach comprises three modes of bank throwing, ship throwing and traction throwing;

as shown in fig. 7 and 8, for example, bank throwing is to directly push and throw the water-filled mesh bag assembly from the bank into the break mouth, which is suitable for plugging the break mouth close to the bank, except for direct manual pushing and throwing and mechanical pushing and throwing, specifically, two groups of inflatable balls can be placed on the bank of the break mouth as a base, then the water-filled mesh bag assembly which is not filled with water is placed on the base, then water filling operation is performed, until the water filling operation is finished, one group of the two groups of inflatable balls as the base, which is close to the break mouth, is deflated, a height difference is formed at the bottom of the water-filled mesh bag assembly, so that the water-filled mesh bag assembly with a larger volume after water filling automatically rolls into the break mouth, in the process, as shown in fig. 7, two groups of top piles 116 need to be respectively arranged on the two banks of the break mouth, a bottom hook rope 117 needs to be wound on the top pile 116, and the bottom hook rope 117 is sequentially wound on each water-filled mesh bag assembly thrown into the break mouth, and fixing the water-filled mesh bag assembly thrown into the break opening inside the break opening so as to stack a plurality of water-filled mesh bag assemblies together layer by layer.

For example, in ship throwing, a water-filling mesh bag assembly is placed on a ship and is suitable for plugging a break port far away from the shore and a break port with a large port door, specifically, as shown in fig. 9, a throwing bag ship 119 is fixed to a position where the break port needs to be plugged through a cable, water in the water-filling mesh bag assembly is filled on the ship, the water-filling mesh bag assembly is placed on one side of the throwing bag ship 119 in the water filling process of the water-filling mesh bag assembly, after the water-filling mesh bag assembly is filled with water, the ship body slightly inclines, the water-filling mesh bag assembly can be pushed into the water by using less thrust, and in the process, the bottom hook rope 117 can be bound on a keel 120 of the throwing bag ship 119.

For example, the water filling mesh bag assembly is filled with water at the bank in the traction throwing mode, a traction rope is additionally arranged on the water filling mesh bag assembly at the moment, one end of the traction rope (the traction rope can replace the bag fixing effect of a remaining rope) is fixed at the bank, the water filling mesh bag assembly is pulled and flowed to the occupation position through the traction rope, and a user can pull on a ship in the process and can pull on the bank so as to be suitable for the placement of the water filling mesh bag assemblies at different positions.

Furthermore, in the method for blocking the breach, a plurality of water-filled mesh bag components are stacked and climbed to form a wall body, before the opening door is closed and air-tight operation is carried out, in order to increase the stability of the wall body, a group of horse riding piles with a cross structure can be fixedly arranged on the back water surface of the wall body, the bottoms of the horse riding piles are inserted into the deep water bottom of the breach, a group of fixing pull ropes are synchronously tied at the center of the horse riding piles, the other ends of the fixing pull ropes are tied on a cast anchor or a cast cage or a towing ship to increase the stability of the wall body, then air-tight operation is carried out, the process can effectively improve the tolerance of the wall body for bearing water flow impact, and the stability is higher.

Example 6:
