Description

Technical Field

[0001] This invention relates to the field of flood control technology, and in particular to a prestressed flood wall that can be quickly erected and its usage method. Background Technology

[0002] Currently, the flood control walls used in some water conservancy projects are temporary, detachable flood control walls. During non-flood seasons, after the flood control walls are dismantled, they need to be transported to designated locations. During the flood season, they mainly rely on their own weight to maintain stability, requiring heavy walls to achieve the effect of flood control.

[0003] However, each time the flood wall needs to be disassembled and reassembled, it requires long-distance transportation and a large amount of manpower for assembly. This not only affects the construction efficiency of the flood wall, but also inevitably causes damage to the wall during transportation, thus affecting its service life.

[0004] Therefore, a prestressed flood control wall that can be quickly erected and its usage method are proposed to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes a prestressed flood control wall that can be rapidly constructed, comprising a bottom fixed wall, which is connected to a bottom movable wall via a pivot device; an upper fixed wall is connected to the top of the bottom fixed wall, which is connected to the upper movable wall via a pivot device, and the bottom of the upper movable wall is connected to the top of the bottom movable wall.

[0039] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0040] See Figures 1 to 8 A prestressed flood control wall that can be quickly erected includes a bottom fixed wall 1, which is connected to a bottom movable wall 2 via a pivot device 15; an upper fixed wall 3 is connected to the top of the bottom fixed wall 1, and the upper fixed wall 3 is connected to an upper movable wall 4 via a pivot device 15; the bottom of the upper movable wall 4 is connected to the top of the bottom movable wall 2.

[0041] The bottom fixed wall 1 and the bottom movable wall 2 are provided with a pop-out first filling box 603; the upper fixed wall 3 and the upper movable wall 4 are provided with a pop-out second filling box 604, and the first filling box 603 and the second filling box 604 are connected to the limiting plate 7 in the vertical direction through the slot 602 to form a whole.

[0042] The bottom fixed wall 1, the bottom movable wall 2, the upper fixed wall 3, and the upper movable wall 4 are all provided with longitudinal anchor cable holes 5.

[0043] Preferably, the bottom fixed wall 1, the bottom movable wall 2, the upper fixed wall 3 and the upper movable wall 4 are all provided with upper grooves 10 and lower grooves 11 on their side walls, and the upper grooves 10 and lower grooves 11 are respectively fixed to the two ends of the support plate 9.

[0044] Preferably, the top of the bottom fixed wall 1, the bottom movable wall 2, the upper fixed wall 3, and the upper movable wall 4 are all provided with inverted T-shaped slots 12, and the bottom of the upper fixed wall 3 and the upper movable wall 4 are provided with inverted T-shaped limiting blocks 13 adapted to the inverted T-shaped slots 12. The upper wall can be quickly embedded and connected through the inverted T-shaped slots 12 of the bottom wall. The structure of the inverted T-shaped slots 12 of the bottom wall can hold the inverted T-shaped limiting blocks 13 of the upper wall, making the wall more stable and allowing the wall to be quickly assembled. When the flood season is approaching and the expected flood height exceeds the height of the entire wall, flood control personnel can raise the wall by adding an upper wall. The upper fixed wall 3 and the upper movable wall 4 can be rotated and embedded into the upper wall to increase the overall height of the wall and prevent floodwater from overflowing the flood control wall.

[0045] Preferably, the bottom fixed wall 1, the bottom movable wall 2, the upper fixed wall 3, and the upper movable wall 4 are all provided with connection ports 14 on their opposite sidewalls. Each connection port 14 can be used to connect the walls via connecting plates 8, with both ends of the connecting plates 8 extending into the connection ports 14 provided on the side walls. By connecting each section of the wall with the connecting plates 8, a solid whole is formed, improving the overall structural strength of the flood control wall and enabling rapid construction.

[0046] Preferably, the limiting plate 7, connecting plate 8, and supporting plate 9 are stacked together with dimensions consistent with the internal space of the inverted T-shaped slot 12, allowing them to be fitted into a single unit. During non-flood seasons, the bottom fixed wall 1 and the bottom movable wall 2 are rotated and stacked via a pivot device. Pushing down the bottom wall allows the water-retaining surface to contact the ground. The upper fixed wall 3 and the upper movable wall 4 are then placed in the same manner, placing the limiting plate 7, connecting plate 8, and supporting plate 9 entirely into the inverted T-shaped slot 12. This design facilitates placement, avoids obstructing the embankment landscape, and allows for easy storage and disassembly when not in use.

[0047] Preferably, the support plate 9 is a cuboid structure with a bendable design; when it is retracted into the inverted T-shaped slot 12, it is a long strip structure, and can be bent and fixed when used for connection and support with the upper slot 10 and the lower slot 11. It can provide triangular support for the wall and enhance the stability of the wall.

[0048] Preferably, the anchor cable hole 5 is a through hole design, and the spring device 601 is a press-type retractable structure. During the flood season, steel cables need to be inserted into the anchor cable hole 5 to provide prestress to the wall, enhancing the stability of the entire wall and effectively improving its flood resistance. When the flood ends, the steel cables will be removed through the anchor cable hole 5.

[0049] Preferably, the first filling box 603 and the second filling box 604 are respectively installed in each wall via spring devices 601.

[0050] Preferably, the first filling box 603 has an open top and an open outer wall, while the second filling box 604 has an open top and bottom and an open outer wall. After the first filling box 603 and the second filling box 604 are ejected, their sides are connected by a sliding block 605, and their outer walls are connected by a limiting plate 7, thus forming an integral columnar structure. During non-flood seasons, the limiting plate 7 is placed above the connecting plate 8 and the support plate 9 to limit the displacement of the connecting plate and the support plate. During flood seasons, the limiting block is placed in the slot of the filling box, and stones and other materials are added to the first filling box 603 and the second filling box 604 to increase the overall weight of the wall, thereby increasing friction and preventing stones from falling and injuring pedestrians. This also helps to form an interconnected whole, creating a wall that provides support for the flood-retaining wall, further enhancing the wall's flood control capabilities.

[0051] In addition, this invention also discloses a method for using a prestressed flood control wall that can be quickly erected, comprising the following steps:

[0052] Step 1: Transport the bottom fixed wall 1, the bottom movable wall 2, the upper fixed wall 3 and the upper movable wall 4 to the site, and take out the limiting plate 7, the connecting plate 8 and the support plate 9 for later use.

[0053] Step 2: Set the bottom fixed wall 1 and the bottom movable wall 2 on the required flood control dike, and unfold the bottom fixed wall 1 and the bottom movable wall 2 through the rotating shaft device 15.

[0054] Step 3: First, unfold the upper fixed wall 3 and the upper movable wall 4 through the rotating shaft device 15, and then connect them to the upper fixed wall 3 and the upper movable wall 4 through the inverted T-shaped slot 12 of the lower fixed wall 1 and the lower movable wall 2 and the inverted T-shaped limiting block 13 of the upper fixed wall 3 and the upper movable wall 4.

[0055] Step 4: Anchor the entire wall with steel cables through anchor cable holes 5. Pop out the first filling box 603 and the second filling box 604 with spring device 601. Connect the two sides of the first filling box 603 and the second filling box 604 in the vertical direction with sliding insert 605. Use limiting plate 7 to slide into filling box 6 through slot 602 at the outer wall.

[0056] Step 5: Insert both ends of the connecting plate 8 into the pre-reserved connection ports 14 between the bottom fixed wall 1 and the bottom movable wall;

[0057] Step 6: After bending the support plate 9 into shape, insert both ends into the upper groove 10 and lower groove 11 of each wall.

[0058] Step 7: After the flood season ends, dismantle and recycle it.

[0059] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
