Description

Technical Field

[0001] This utility model belongs to the field of water conservancy, municipal production and domestic water supply technology, and specifically relates to a prefabricated steel plate water tank. Background Technology

[0002] Prefabricated water storage tanks are a type of water storage tank that can be quickly assembled. This type of tank uses prefabricated components, which are assembled into a large-scale structure. On-site construction requirements are low, the process is fast, and the tanks are movable and easily recyclable, without permanently occupying land. They offer excellent adaptability and cost-effectiveness. However, their disadvantages are also obvious. The walls of thin-walled steel plate tanks bear the weight of the tank wall itself plus the weight of the water directly above it. When the tank wall is strictly vertical, the weight of the water directly above it is zero, and the tank wall only bears its own weight. When the tank undergoes elliptical deformation due to installation errors, foundation settlement, or external forces such as earthquakes, the upper part of the tank wall protrudes outward, causing the tank wall to tilt. Water forms directly above this protruding part of the tilted wall, increasing the downward pressure on this portion and forcing the tank wall to tilt further. Therefore, the deformation of the outer wall always leads to more unfavorable stress conditions, creating a vicious cycle that can easily lead to damage and safety accidents. The thin walls of the pool have weak resistance to deformation and a high risk of tipping over. While maintaining its economic efficiency, it is not easy to improve its rigidity, making it difficult to meet the requirements of use scenarios with high safety requirements, which greatly limits its application range. Utility Model Content

[0003] This utility model provides a prefabricated steel plate water tank, the purpose of which is to provide a prefabricated water storage tank with stronger resistance to deformation, so as to meet the requirements of use scenarios with high safety requirements.

[0004] A prefabricated steel plate water tank with a reinforcing device, characterized in that: the device includes a central column, an inner tank, a steel plate, a hoop, a vertical plate, and a telescopic cable;

[0005] The central column is vertically buried in the pit dug on the ground using gravel. The depth of the central column is not less than 1 / 6 of its total height. Several hooks are evenly arranged around the top and upper part of the central column.

[0006] The outer wall is set around the central column as the center. The outer wall is composed of vertical plates, hoops and steel plates. The vertical plates are set vertically and evenly around the center. The lifting lugs are fixed at the top of the vertical plates. The hoops are set horizontally on the inner side of the vertical plates, with the hoops being denser at the bottom and sparser at the top. The hoops and vertical plates are connected to form a grid structure. The steel plates are closely attached to the inner side wall of the grid structure and bolted or anchored to it as a whole. The lifting lugs are connected to the hooks at the top of the central column using telescopic cables.

[0007] The inner liner is fitted tightly against the inner wall of the steel plate and the central column. The center of the inner liner is set with a sleeve that matches the outer diameter of the central column. The sleeve of the inner liner is closed to the central column and fixed to the hook on the central column. The outer edge of the top of the inner liner is connected to the top of the outer wall. The top surface of the inner liner has a rainwater collection hole with mesh and an inspection port.

[0008] A detachable vertical pipe is installed at the bottom of the inner tank. The pipe opening is sealed to the inner tank and the pipeline through a composite water tank connector. A tee is installed at the outer end of the vertical pipe to connect to the water intake pipe and the sludge discharge pipe respectively. Both pipe openings are equipped with gate valves.

[0009] The inner liner is made of a flexible material.

[0010] Furthermore, a suspension rope is provided between the cable and the top surface of the inner liner for fixation.

[0011] Furthermore, the telescopic cable includes a cable and a turnbuckle, and the cable is telescopically adjusted by means of the turnbuckle.

[0012] Furthermore, the access panel is opened and closed by a zipper.

[0013] Furthermore, a lightning rod is connected to the top of the central column, and a grounding grid is buried around the water tank and connected to the outer wall. The lightning rod is connected to the grounding grid through the outer wall.

[0014] Furthermore, a detachable vertical pipe is provided at the bottom of the inner tank. Removing the vertical pipe facilitates the cleaning and sand removal of the water cellar.

[0015] The beneficial effects of this invention are as follows: By using columns and cables, the pressure is transmitted to the central column with high compressive strength, transforming the downward pressure on the outer wall structure into upward tension. This completely changes the mechanical characteristics of the pool wall load under water storage conditions, converting the force characteristics that maintain the pool's shape from a positive feedback mechanism to a negative feedback mechanism. The suspension system is a symmetrical structure. When the pool body deforms outwards, the corresponding cables tighten, increasing the tension; when it deforms inwards, the cables loosen, decreasing the tension. The direction of stress increase is opposite to the direction of deformation. This negative feedback stress mechanism always prompts the structure to return to its original shape, fully utilizing the excellent tensile strength of the thin-walled steel plate as the main material of the pool. The strengthening device can safely reduce the stiffness requirements of the main material of the pool, or use materials of equal strength to build a taller pool, optimizing the shape design, reducing material consumption per unit volume, thereby reducing costs and land occupation. The enclosed inner tank surrounds the central column, relying on the deeply buried column to resist overturning, reducing the risk of overturning. Compared to open water tanks, closed structures significantly reduce the peak flow rate of leaked water in the event of localized damage, thus mitigating the risk of injury to people and property in the surrounding area and downstream. This device significantly improves the safety of prefabricated steel plate water tanks, enriches their functionality, and further enhances their convenience and economy. It can be widely applied in water conservancy and municipal engineering projects, facilitating the rapid promotion and safe use of this type of water tank. Attached Figure Description
