Description

Technical Field

[0001] This utility model relates to the field of flood control equipment technology, and more specifically, to a PVC flood control dam. Background Technology

[0002] Traditional flood control facilities (such as sandbag dams and earth-rock dams) suffer from drawbacks such as low deployment efficiency, poor mobility, and insufficient terrain adaptability. Sandbag dams require a large amount of manpower to build, taking several hours, and are prone to leakage; earth-rock dams damage the ground surface and are not reusable. Existing water-filled retaining structures mostly use fixed concrete or metal materials, which cannot be quickly assembled or disassembled. Although some inflatable dams have emerged, they lack modular splicing designs and self-filling gravity reinforcement mechanisms, making it difficult to balance overturning stability and terrain adaptability. Therefore, there is an urgent need for a flood control technology that can be quickly deployed, flexibly adapt to complex terrain, and possess high water tightness. Utility Model Content

[0003] The problem this invention addresses is: how to provide flood control facilities that can be quickly deployed and flexibly adapted to complex terrain.

[0004] To solve the above problems, this utility model provides a PVC flood control dam, comprising: The dam body is made of high-strength PVC membrane material, which has a thickness of 0.9~1.2mm and has an anti-ultraviolet coating; An energy-charging cavity is located inside the dam body, which expands by inflating with air or water to form a rigid water-blocking structure; An anchoring system installed along the bottom of the dam body, including ground nails and / or counterweight foot structures; Modular connectors located on the sides of the dam body are used to splice adjacent dam body modules.

[0005] Optionally, the charging cavity includes an independent airbag unit and a water filling unit, wherein the water filling unit has a water inlet with a filter screen at its bottom for automatically filling with water when floodwaters rush in.

[0006] Optionally, the modular connector is a snap-fit ​​interface or a sleeve interface to achieve sealed splicing of adjacent dam modules in the length direction. The height of a single dam module is 0.5 to 2 meters and the length is 10 to 20 meters.

[0007] Optionally, the water filling unit is connected to the water inlet to form a self-filling structure. After filling with water, the weight of the water increases the dam's anti-overturning moment, and the cross-section of the water filling unit is trapezoidal to expand the bottom counterweight area.

[0008] Optionally, the anchoring system includes ground nails spaced 0.5 to 1 meter apart, with a depth of 30 to 50 cm, and connected to the bottom of the dam body by nylon ropes; and / or the counterweight foot structure is composed of sandbags or stones stacked on the outside of the dam body.

[0009] Optionally, it also includes a detachable heightening module installed on the top of the dam body. The heightening module is an inflatable extension section or a layer of flood control sandbags, used to temporarily raise the water-retaining height by 0.3 to 0.5 meters.

[0010] Optionally, the dam body is equipped with a pressure regulating valve and a drain valve, wherein the pressure regulating valve is used to maintain the inflation pressure at 0.02~0.05MPa, and the drain valve is located at the bottom of the charging chamber.

[0011] Compared with the prior art, the PVC flood control dam of this utility model has the following beneficial effects: This invention involves clearing sharp objects from the ground before laying the high-strength PVC membrane dam; inflating the cavity into a rigid structure through air / water filling; fixing the dam base with an anchoring system; and splicing adjacent dam sections with modular connectors. The watertightness of the PVC membrane blocks water flow; the inflatable cavity provides structural support; and the anchoring system resists horizontal thrust.

[0018] like Figures 1 to 3 As shown, this utility model embodiment provides a PVC flood control dam, comprising: The dam body 101 is made of high-strength PVC membrane material, which is 0.9~1.2mm thick and has an anti-ultraviolet coating; An energy-charging cavity 102 is located inside the dam body 101. The energy-charging cavity 102 expands by inflating with air or water to form a rigid water-retaining structure. An anchoring system 103 installed along the bottom of the dam body 101 includes ground nails and / or counterweight foot structures; The modular connector 104, located on the side of the dam body 101, is used to splice adjacent dam body modules.

[0019] A high-strength PVC membrane dam body 101 is laid, and sharp objects on the ground are cleared. The cavity 102 is inflated into a rigid body by inflation / water filling. The dam base is fixed with an anchoring system 103, and adjacent dam bodies are spliced ​​together using modular connectors 104. The watertightness of the PVC membrane blocks water flow; the inflatable cavity 102 provides structural support; and the anchoring system 103 resists horizontal thrust. This allows for rapid deployment and reduces manpower input.

[0020] The charging cavity 102 includes an independent airbag unit 102a and a water filling unit 102b, wherein the bottom of the water filling unit 102b is provided with a water inlet 105 with a filter screen for automatically filling with water when floodwaters rush in.

[0021] Floodwater is automatically injected into the water filling unit 102b through the bottom filter inlet 105. The weight of the water increases the dam's anti-overturning moment and improves its anti-overturning capacity.

[0022] Modular connector 104 is a snap-fit ​​interface or sleeve interface, which realizes the sealed splicing of adjacent dam modules in the length direction. The height of a single dam module is 0.5~2 meters and the length is 10~20 meters.

[0023] The snap-fit / sleeve interface 104 connects to adjacent dam modules. The interface is mechanically locked and equipped with a sealing strip to prevent leakage. The length can be freely combined according to the actual needs to adapt to different usage requirements.

[0024] The water filling unit 102b is connected to the water inlet 105 to form a self-filling structure. After filling with water, the weight of the water increases the dam's resistance to overturning moment. The cross-section of the water filling unit 102b is trapezoidal to expand the bottom counterweight area.

[0025] Optionally, the cross-section of the water-filling unit 102b is designed as a trapezoid, with the bottom width being greater than the top width. The trapezoidal structure increases the bottom counterweight area and lowers the center of gravity.

[0026] The anchoring system 103 includes ground nails spaced 0.5 to 1 meter apart, with a depth of 30 to 50 cm, and connected to the bottom of the dam body 101 by nylon ropes; and / or the counterweight foot structure consists of sandbags or stones stacked on the outside of the dam body 101.

[0027] Optionally, when using ground nails for fixing, drive in ground nails 103a with a depth of 40cm every 0.8m, and tighten the dam body with nylon ropes; when using counterweights for fixing, stack sandbags 103b on the outside of the dam body to form a 0.5m wide pressure foot.

[0028] It also includes a detachable heightening module 107 installed on top of the dam body 101. The heightening module 107 is an inflatable extension section or a layer of flood control sandbags, used to temporarily raise the water-retaining height by 0.3 to 0.5 meters. When the flood exceeds the limit, an inflatable extension section 107 or a layer of sandbags is added to the top of the dam to increase the height according to the actual working conditions.

[0029] The dam body 101 is equipped with a pressure regulating valve 108 and a drain valve 109. The pressure regulating valve 108 is used to maintain the inflation pressure at 0.02~0.05MPa, and the drain valve 109 is located at the bottom of the charging chamber 102.

[0030] The pressure regulating valve 108 maintains the working pressure; the drain valve 109 quickly empties the cavity. The constant pressure valve counteracts pressure fluctuations caused by temperature; the drain valve utilizes gravity to drain the air.

[0031] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
