Description

Technical Field

[0001] The present invention relates to the field of construction, and particularly to a liftable building for flood detention areas. Background Art

[0002] Under emergency flood control conditions, the buildings in flood detention areas are often submerged by the flood water at high water levels, resulting in the interior and exterior decorations of the buildings being soaked by the flood. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a liftable building for flood detention areas, which can change the vertical equilibrium position of the building main body by the pressure difference provided by the water accumulated by rainfall without external power, so that the building main body can be lifted and lowered automatically.

[0004] To solve the above technical problem, the technical solution of the present invention is: a liftable building for flood detention areas, including a building main body and a plurality of automatic jacking mechanisms arranged along the circumference of the building main body. The automatic jacking mechanism includes a U-shaped pipe, a first seal, a second seal, and a water storage tank; wherein,

[0005] The U-shaped pipe is buried in the foundation. The first seal is slidably sealed in the water storage tank. The water storage tank is located above the U-shaped pipe, with an open upper end and a lower end communicating with the opening of the first end of the U-shaped pipe. The second seal is slidably sealed in the second end of the U-shaped pipe, connecting and supporting the building main body. The sealing cavity formed by the first seal, the water storage tank, the U-shaped pipe, and the second seal is filled with liquid.

[0017] 3. Each water storage tank is connected, which can ensure that the water level heights of each water storage tank are the same, thus realizing the uniform lifting and lowering of the building body. Description of the Drawings

[0018] Figure 1 It is a schematic structural diagram of the liftable building for flood storage and detention area of the present invention. Detailed Embodiments

[0019] In order to make the content of the present invention easier to be clearly understood, the present invention will be further described in detail below according to specific embodiments and in conjunction with the drawings.

[0020] As Figure 1 shown, a liftable building for flood storage and detention area includes a building body 1 and a number of automatic lifting mechanisms arranged along the circumference of the building body 1. The automatic lifting mechanism includes a U-shaped pipe 2, a first seal 3, a second seal 4 and a water storage tank 5; wherein,

[0021] The U-shaped pipe 2 is buried in the foundation. The first seal 3 is slidably sealed in the water storage tank 5. The water storage tank 5 is located above the U-shaped pipe 2, with an upper opening and a lower end connected to the opening of the first end of the U-shaped pipe 2. The second seal 4 is slidably sealed in the second end of the U-shaped pipe 2, connecting and supporting the building body 1. The sealed cavity formed by the first seal 3, the water storage tank 5, the U-shaped pipe 2 and the second seal 4 is filled with liquid. A counterweight 8 is arranged on the first seal 3. The counterweight 8 can be a concrete counterweight, but is not limited thereto.

[0022] In this embodiment, the first seal 3 and the second seal 4 are respectively in contact with the liquid levels of the water storage tank 5 and the liquid in the U-shaped pipe 2. When there is no water above the first seal 3, the liquid level in the second end of the U-shaped pipe 2 is lower than that in the first end. The hydraulic pressure difference formed by the liquid in the U-shaped pipe plus the counterweight 8 just supports the weight of the building body 1 borne by the second seal 4, and the building is at the lowest elevation before lifting. After the water storage tank 5 is filled with water, the pressure difference formed on both sides of the U-shaped pipe 2 can lift the building body 1 to the expected height.

[0023] In this embodiment, the building body 1 can be in any form. A ring beam or a floor slab should be provided at the bottom of the building body 1. The second seal 4 is connected to the ring beam or the floor slab of the building body 1. An appropriate number of automatic jacking mechanisms can be configured according to the weight of the building body 1, and the weights borne by each second seal 4 are equal. To reduce the weight of the counterweight 8, the building body 1 preferably adopts a lightweight structure.

[0024] Specifically, when a flood disaster occurs in the flood storage area, the water storage tank 5 receives the rainwater from the eaves and / or collects floodwater. The water stored in the water storage tank 5 causes a pressure difference between the first end and the second end of the U-shaped pipe 2, so that the second seal 4 slidingly fitted to the U-shaped pipe 2 is evenly lifted until a new balance state is reached for the pressure difference on both sides of the U-shaped pipe 2, and the building body 1 rises smoothly accordingly, and the building body 1 is thus protected from the flood. After the flood is over, the rainwater inside the water storage tank 5 is released, so that the second seal 4 drops below the foundation and restores the original building elevation. Compared with the existing fixed buildings in the flood storage and detention area, the liftable building proposed in this embodiment can effectively prevent the building body 1 from being flooded by the flood and reduce the losses caused by the building body 1 being soaked by the flood; by using the pressure difference formed by the collected floodwater and the rainwater from the eaves in the water storage tank 5 to change the vertical positions at both ends of the U-shaped pipe 2, the building body 1 can be lifted and lowered without external power, which not only saves costs but also effectively solves the problem of shortage of external power caused by the lack of electricity due to the flood in the flood storage and detention area.

[0025] As Figure 1 shown, the lower ends of the parts of any two adjacent water storage tanks 5 above the first seal 3 are interconnected. In this embodiment, the lower ends of the parts of any two adjacent water storage tanks 5 above the first seal 3 are interconnected through a cross pipe 6, and the cross pipe 6 is used to quickly distribute the water volume in the water storage tank 5 so that the water levels in all the water storage tanks 5 are at the same elevation.

[0026] As Figure 1As shown, the first seal 3 is a sealing partition board, and two openings are provided. One opening is connected to the horizontal pipe 6 through a hose 9, and the other opening is connected to the drain valve 7 through a hose 9. The drain valve 7 is provided to facilitate draining the water in the water storage tank 5 according to actual needs. The second seal 4 is a piston cylinder, the piston cylinder is cylindrical, and at least a part of it always exposes the opening of the U-shaped pipe 2.

[0027] In this embodiment, the liquid is heavy oil. Heavy oil has good physical properties. Compared with other liquids such as water, it is not easy to volatilize and is more stable. In addition, heavy oil has better economy, and the required economic cost is lower compared with other liquids. The liquid can also be mercury. The density of mercury is relatively large. For the same height difference, a relatively large pressure can be generated compared with other liquids such as water.

[0028] In this embodiment, a concrete counterweight 8 is provided above the first seal 3 inside the water storage tank 5. With such a setting, the water storage capacity of the water storage tank 5 required during building jacking can be significantly reduced.

[0029] As Figure 1 shown, the water storage tank 5 is at least used to receive the eaves water of the building main body 1.

[0030] Enlightened by the above ideal embodiments according to the present invention, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
