Description

Technical Field

[0001] This utility model relates to the field of riverbank protection, and in particular to a riverbank protection method that is easy to construct. Background Technology

[0002] Currently, during the construction of riverbank protection, it is necessary to solidify the soil on both sides of the river. The most common solidification method is to lay cement on the rolled and leveled soil to protect the soil and water on both sides, thereby preventing excessive erosion of the soil on both sides of the river by the water flow.

[0003] Currently, a common technique used in riverbank protection construction is to level the soil and then lay a cement blanket on top of the leveled soil, followed by watering to solidify the blanket and prevent erosion of the soil on both banks by water flow.

[0004] However, the current construction of riverbank protection has the following shortcomings: it is inconvenient to splice and fix the joints between adjacent cement blankets, and the size of each splice is different, resulting in different processes after the entire river channel is laid. In addition, it is inconvenient to fix one end before laying to make the adjacent cement blankets flush. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a riverbank protection system that is easy to construct.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A riverbank protection that is easy to construct includes a dam, an outer cement blanket, a middle cement blanket and an inner cement blanket. A set of outer cement blankets, multiple sets of middle cement blankets and a set of inner cement blankets are laid flat and stacked adjacent to each other on the dam. Rotating lifting rings are installed on the outer cement blanket, the middle cement blanket and the inner cement blanket. Limiting pins are fixed at equal intervals on the dam. Limiting pins are fitted inside the rotating lifting rings.

[0007] Preferably, in the above-mentioned easy-to-construct riverbank revetment, the outer cement blanket, the middle cement blanket, and the inner cement blanket all have the same thickness and width, and the top structures of the outer cement blanket, the middle cement blanket, and the inner cement blanket are also the same.

[0008] Preferably, in the above-mentioned riverbank revetment that is easy to construct, the lower left half of the outer cement blanket is provided with a first side connecting groove, the left side of the outer cement blanket is attached to the middle cement blanket, and the left and right ends of the middle cement blanket are respectively provided with a first mounting pad and a second side connecting groove.

[0009] Preferably, in the above-mentioned easy-to-construct riverbank revetment, the thickness and length of the side of the first mounting pad located on the right side of the intermediate cement blanket are the same as the thickness and length of the side of the first side connecting groove, and the thickness of the first mounting pad is half the thickness of the intermediate cement blanket.

[0010] Preferably, in the above-mentioned easy-to-construct riverbank revetment, the two limiting pins are grouped together, the distance between each group of limiting pins and the width of the intermediate cement blanket are the same, the upper ends of the intermediate cement blanket are fixed with welded pipes, and the center of the welded pipes away from the intermediate cement blanket is provided with threaded holes.

[0011] Preferably, in the above-mentioned easy-to-construct riverbank revetment, the welded pipe and the rotating lifting ring form a detachable structure, and the inner diameter of the rotating lifting ring is larger than the outer diameter of the limiting pin.

[0012] The beneficial effects of this utility model are as follows: Two sets of rotating lifting rings installed on the outer cement blanket are placed inside the corresponding limiting pins, providing initial fixation of the outer cement blanket. Through the cooperation of multiple sets of rotating lifting rings and limiting pins, the upper end of the cement blanket can be made flush. This also prevents the outer cement blanket from slipping when unfolded. Through the cooperation of the first side connecting groove, the first mounting pad, the second side connecting groove, and the second mounting pad, multiple sets of intermediate cement blankets are stacked on top of the outer cement blanket, with some intermediate cement blankets overlapping each other at adjacent ends. Finally, the inner cement blanket is used for finishing. This splicing method allows the cement blankets to be placed more neatly and with higher flatness. Attached Figure Description

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figures 1-6 As shown, a riverbank protection structure that is easy to construct includes a dam 1, an outer cement blanket 2, a middle cement blanket 3, and an inner cement blanket 4. A set of outer cement blankets 2, multiple sets of middle cement blankets 3, and a set of inner cement blankets 4 are sequentially and adjacently stacked on the dam 1. Rotating lifting rings 5 ​​are installed on the outer cement blankets 2, middle cement blankets 3, and inner cement blankets 4. Limiting pins 6 are fixed at equal intervals on the dam 1, and the rotating lifting rings 5 ​​are internally fitted with limiting pins 6. A second mounting pad is provided on the right side of the inner cement blanket 4. The second mounting pad and the first mounting pad 33 are the same size and shape. The second mounting pad on the right side of the inner cement blanket 4 is fitted and spliced ​​with the second side connecting groove 34 on the left side of the middle cement blanket 3. The first mounting pad 33 on the right side of the middle cement blanket 3 is fitted and spliced ​​with the first side connecting groove 21 on the left side of the outer cement blanket 2. By laying outer cement blankets 2 and inner cement blankets 4 at both ends of the dam 1 and connecting them with the middle cement blanket 3 in the middle, a section of riverbank protection can be quickly laid on the dam 1.

[0023] like Figure 1 , Figure 2 , Figure 5 as well as Figure 6 As shown: the outer cement blanket 2, the middle cement blanket 3, and the inner cement blanket 4 all have the same thickness and width, and their top structures are also identical. A first side connecting groove 21 is provided on the lower left side of the outer cement blanket 2. The middle cement blanket 3 is attached to the left side of the outer cement blanket 2. A first mounting pad 33 and a second side connecting groove 34 are respectively provided on the left and right ends of the middle cement blanket 3. The side thickness and length of the first mounting pad 33 located on the right side of the middle cement blanket 3 are the same as the side thickness and length of the first side connecting groove 21. The thickness of the first mounting pad 33 is half the thickness of the middle cement blanket 3. Multiple sets of middle cement blankets 3 can be stacked sequentially on the outer cement blanket 2, with some adjacent ends of the middle cement blankets 3 overlapping each other. Finally, the inner cement blanket 4 is used to finish, making the left end of the inner cement blanket 4 flush with the embankment 1. This splicing method allows for a more orderly and flatter arrangement of the cement blankets.

[0024] like Figure 4 , Figure 5 as well as Figure 6As shown: Two limiting pins 6 form a group, and the distance between each group of limiting pins 6 and the width of the intermediate cement blanket 3 are the same. Welded pipes 31 are fixed to both sides of the upper end of the intermediate cement blanket 3, and threaded holes 32 are opened at the center of the welded pipes 31 away from the intermediate cement blanket 3. The welded pipes 31 and the rotating lifting rings 5 ​​form a detachable structure, and the inner diameter of the rotating lifting rings 5 ​​is larger than the outer diameter of the limiting pins 6. The two groups of rotating lifting rings 5 ​​installed on the outer cement blanket 2 are placed inside the corresponding limiting pins 6 to initially fix the outer cement blanket 2 and prevent it from sliding when unfolded. At the same time, the size design of the rotating lifting rings 5 ​​and the limiting pins 6 facilitates the fitting of the rotating lifting rings 5 ​​onto the outside of the limiting pins 6.

[0025] Working principle: When laying slope protection on the embankment 1 on both sides of the river channel, firstly, based on the varying spacing of the rotating lifting rings 5 ​​installed on multiple sets of cement blankets, multiple sets of limiting pins 6 are pre-embedded at the upper end of the embankment 1, ensuring that the center distance between two adjacent sets of limiting pins 6 is the same as the center distance of the rotating lifting rings 5 ​​on the cement blanket. During the actual laying of the slope protection, the corresponding cement blanket is lifted and moved by using tools such as forklifts and cranes, by passing lifting ropes (not shown in the figure) through the rotating lifting rings 5. First, after hoisting the outer cement blanket 2, align its right side with the right side of the embankment 1. Then, place the two sets of rotating lifting rings 5 ​​installed on the outer cement blanket 2 into the corresponding limiting pins 6 to initially fix the outer cement blanket 2 and prevent it from slipping when unfolded. Next, stack multiple sets of intermediate cement blankets 3 on top of the outer cement blanket 2, with some intermediate cement blankets 3 overlapping each other at adjacent ends. Finally, use the inner cement blanket 4 to finish, ensuring that the left end of the inner cement blanket 4 is flush with the embankment 1, and the right side of the inner cement blanket 4 is stacked on the second connecting groove 34 on the left side of the intermediate cement blanket 3. After laying the outer cement blanket 2, intermediate cement blanket 3, and second connecting groove 34, water is poured on the cement blankets to allow the cement to harden and adhere better to the embankment 1. After completing the laying of the riverbank protection, the limiting pins 6 can be pulled out from the top of the embankment 1, and the rotating lifting rings 5 ​​can be rotated off the welded pipe 31 for later reuse.
