When water comes outside the construction area, the reinforcing rods 312 can significantly reinforce the strength of the barrier 1 so that the barrier 1 can withstand the water coming.
Referring to fig. 1 and 2, adjacent baffles 1 abut against each other and are connected to each other by a seal assembly 2. The sealing assembly 2 comprises a plug-in part 21 and a bearing part 22, and the plug-in part 21 and the bearing part 22 are respectively arranged on two sides of the same baffle 1. For convenience of description, two adjacent baffles 1 are referred to as a first baffle 1 and a second baffle 1. When the first baffle plate 1 and the second baffle plate 1 are mutually attached, the insertion part 21 on the first baffle plate 1 is inserted into the receiving part 22 on the second baffle plate 1 to realize sealing.

The pushing block 211 can be pushed to move outwards by filling enough liquid into the accommodating groove 11, and finally the sealing strip 212 is driven to move outwards, and the adjacent baffle plates 1 are inserted to form a seal, and the sealing pressure is provided by the liquid, so that the sealing pressure can be flexibly adjusted.
Referring to fig. 3 and 4, the sidewall of the receiving groove 11 facing the incoming water may be moved in the thickness direction of the baffle plate 1, thereby changing the size of the receiving groove 11. When the incoming water is supplied, the liquid is filled in the accommodating groove 11 sufficiently, and the incoming water gives pressure to the side wall of the accommodating groove 11 facing the incoming water, so that the flexible film 213 is pushed to deform, and the flexible film 213 is used as a separation layer between the side wall of the accommodating groove 11 and the liquid, so that the liquid can be kept from leaking when the capacity of the accommodating groove 11 is reduced. The push block 211 is also made of flexible material and has good elasticity. Therefore, when the side wall of the accommodating groove 11 facing the incoming water is moved by the incoming water pressure, deformation can be generated, and the side wall of the accommodating groove 11 facing the incoming water is not interfered to move. Through the pressure of incoming water, the lateral wall of holding tank 11 side towards incoming water can inwards remove the space of extrusion liquid for liquid pressure improves, thereby makes the seal inseparabler, and the sealed effect is better, and the bigger the incoming water pressure is, the better the sealed effect is. And the water can not directly contact with the parts of the sealing part when coming, so that the service life can be prolonged. Referring to fig. 5, a gap between a sidewall of the receiving groove 11 facing the incoming water and the baffle plate 1 may be covered with a sealing film 23, so that the incoming water can be effectively prevented from penetrating into the gap, thereby prolonging the service life.

Referring to fig. 2 and 6, the receiving portion 22 is disposed on the other side of the baffle 1, a receiving groove 12 is formed in the baffle 1, the receiving portion 22 includes a pushing block 223, a receiving groove 221 for receiving the sealing strip 212 is formed in the pushing block 223, and a sealing ridge 222 is disposed in the receiving groove 221 and corresponds to the sealing groove 214. The push block 223 divides the accommodating groove 12 into the first and second chambers 121 and 122, the inner wall of the accommodating groove 12 is covered with the rubber film 224, and the sidewall of the push block 223 is tightly abutted against the inner wall of the accommodating groove 12 so that the first and second chambers 121 and 122 are not communicated with each other. Similarly, a hole for filling liquid is formed in the side wall of the second cavity 122 for filling liquid into the second cavity 122, and the second cavity 122 can be closed by a plug after the second cavity 122 is filled with liquid. The side wall of the second cavity 122 facing the incoming water can also move along the thickness direction of the baffle plate 1, so that the whole size of the accommodating groove 12 can be changed. When the incoming water is supplied, the receiving tank 12 is filled with a sufficient amount of liquid, and the incoming water is applied to the side wall of the receiving tank 12 facing the incoming water, so that the rubber film 224 is pushed to deform, and the rubber film 224 serves as a separation layer between the side wall of the receiving tank 12 and the liquid, so that the liquid can be kept from leaking when the capacity of the receiving tank 12 is reduced. The pushing block 223 is made of flexible material and has good elasticity as the pushing block 211. Therefore, when the side wall of the accommodating groove 12 facing the incoming water is moved by the incoming water pressure, deformation can be generated, and the side wall of the accommodating groove 11 facing the incoming water is not interfered to move. By the pressure of the incoming water, the side wall of the accommodating groove 12 facing the incoming water can move inwards to squeeze the liquid space, so that the liquid pressure is improved, the sealing is tighter, and the sealing effect is better, that is, the greater the incoming water pressure is, the better the sealing effect is. And the water can not directly contact with the parts of the sealing part when coming, so that the service life can be prolonged. Referring to fig. 6 and 7, the gap between the sidewall of the receiving groove 12 facing the incoming water and the baffle plate 1 may be covered with the sealing film 23 as well, so that the incoming water can be effectively prevented from penetrating into the gap, thereby prolonging the service life.

After filling the liquid, the outer wall of lateral wall and the outer wall of baffle 1 are parallel and level each other, and the one end that spout 14 is closest to the outer wall and slide rail 13 have the surplus between this moment, and through the pressure of coming water this moment, the lateral wall of holding tank 12 side towards coming water can inwards remove the space of extrusion liquid for liquid pressure improves, thereby makes sealed inseparabler, and sealed effect is better, and the sealing effect is better that is to say that the more coming water pressure is big. And the water can not directly contact with the parts of the sealing part when coming, so that the service life can be prolonged. Referring to fig. 6 and 7, the gap between the sidewall of the receiving groove 12 facing the incoming water and the baffle plate 1 may be covered with the sealing film 23 as well, so that the incoming water can be effectively prevented from penetrating into the gap, thereby prolonging the service life.

And sealing is achieved by the sealing strip 212 being pressed tightly into the receiving groove 221 by the action of the liquid pressure. The sealing effect is better by matching with the sealing ribs 222 extruded by the liquid bag 218. Meanwhile, as the whole structure for sealing is arranged in the accommodating groove 11 or the accommodating groove 12, incoming water cannot be directly contacted, and the service life of the structure for sealing can be prolonged. And when water comes, the side walls of the accommodating groove 12 and the accommodating groove 11 facing the water coming side can move along the thickness direction of the baffle plate 1, so that the liquid storage space can be extruded when water comes, the liquid storage space is smaller, the pressure of the liquid can be improved, the sealing strip 212 and the receiving groove 221 can be mutually abutted to be more compact, meanwhile, the force of the liquid bag 218 for extruding the sealing convex rib 222 can be larger due to the larger liquid pressure, and the pressure sealing effect is better.
