Flood protective dam and framework thereof

[0024] An embodiment of flood prevention and dam construction, in figure 1 , Combined figure 2 with image 3 The skeleton of the flood control dam is composed of a series of supporting frames 1 and connecting frames 2. The supporting frames 1 are all arranged in parallel, and two groups of connecting frames are arranged between two adjacent supporting frames 1, one of which is a connecting frame. It is arranged on one side of the support frame 1, and another set of connecting frames is arranged on the other side of the support frame 1. Each set of connecting frames has two connecting frames 2, and the length and width of the two connecting frames 2 are correspondingly equal. The two connecting frames 2 are rotatably assembled together on one side, and the other side of the two connecting frames 2 is rotatably assembled with corresponding two adjacent support frames 1 respectively. In this way, the two sets of connecting frames connect the two adjacent support frames 1 together, and every two adjacent support frames 1 and the four connecting frames 2 connecting them form a square space. The square space of is filled with sandstone layer 3. The gravel layer 3 fills up each square space to form a dam.

[0025] Nylon fabrics are laid on the sides of the supporting frame 1 and the connecting frame 2 facing the square space. One side of the nylon fabric is in contact with the supporting frame 1 or the connecting frame 2, and the other side is in contact with the sand layer 3, making the supporting frame 1 And the connection between the connecting frame 2 and the gravel layer 3 is closer.

[0026] The overall structure of the supporting frame and the connecting frame is the same. The outer frame is a square steel frame bent from a steel pipe. A steel wire mesh 5 is arranged inside the square steel frame 4, and the four sides of the steel wire mesh 5 are welded separately On the four sides of the square steel frame.

[0027] The structure of the supporting frame and the connecting frame in this embodiment are the same. Of course, the supporting frame can also be of other structures. For example, the outer side of the supporting frame can have a square steel frame with the above-mentioned structure, and a pair of square steel frames can be provided between the two sides The steel pipes parallel to each other, the two ends of each steel pipe are respectively fixed on the two opposite sides of the square steel frame.

[0028] The flexible fabric in this embodiment is a nylon fabric, and it can also be a fabric of other high-strength fibers, such as a fabric of polyparaphenylene terephthalamide.

[0029] In this embodiment, the length and width dimensions of two connecting frames in a group of connecting frames are correspondingly equal, and of course they may not be equal.

[0030] When in use, first transport the support frame and connecting frame produced by the factory to the site, assemble it, and fill the square space enclosed by the support frame and the connecting frame with sand and tamping.

[0031] In this embodiment, the square space enclosed by the supporting frame and the connecting frame is filled with a sand-gravel layer, or a sand-soil layer.

[0032] An example of a framework for flood control and dam construction, in figure 2 with image 3 In this embodiment, the skeleton in this embodiment is the skeleton in the above embodiment of flood control and damming, and the structures of the two are completely the same. The skeleton in this embodiment is also composed of a series of supporting frames 1 and connecting frames 2. The supporting frames 1 are all arranged in parallel, and two groups of connecting frames are arranged between two adjacent supporting frames 1, one of which is a connecting frame. It is arranged on one side of the support frame 1, and another set of connecting frames is arranged on the other side of the support frame 1. Each set of connecting frames has two connecting frames 2, and the length and width of the two connecting frames 2 are correspondingly equal. The two connecting frames 2 are rotatably assembled together on one side, and the other side of the two connecting frames 2 is rotatably assembled with corresponding two adjacent support frames 1 respectively. In this way, the two sets of connecting frames connect the two adjacent support frames 1 together, and every two adjacent support frames 1 and the four connecting frames 2 connecting them form a square space.

[0033] Nylon fabrics are laid on the sides of the supporting frame and the connecting frame facing the square space.

[0034] The overall structure of the supporting frame and the connecting frame is the same. The outer frame is a square steel frame bent from a steel pipe. A steel wire mesh 5 is arranged inside the square steel frame 4, and the four sides of the steel wire mesh 5 are welded separately On the four sides of the square steel frame.

[0035] The structure of the supporting frame and the connecting frame in this embodiment are the same. Of course, the supporting frame can also be of other structures. For example, the outer side of the supporting frame can have a square steel frame with the above-mentioned structure, and a pair of square steel frames can be provided between the two sides The steel pipes parallel to each other, the two ends of each steel pipe are respectively fixed on the two opposite sides of the square steel frame.

[0036] The flexible fabric in this embodiment is a nylon fabric, and it can also be a fabric of other high-strength fibers, such as a fabric of polyparaphenylene terephthalamide.

[0037] In this embodiment, the length and width dimensions of two connecting frames in a group of connecting frames are correspondingly equal, and of course they may not be equal.
