Description

Technical Field

[0001] This utility model belongs to the field of municipal production and domestic water supply technology, specifically relating to an assembled steel plate water tank with a high-strength reinforcement device. Background Technology

[0002] Prefabricated steel plate water tanks bear the weight of the tank walls themselves and the weight of the water directly above them. When the tank walls are strictly vertical, the weight of the water directly above them is zero, and the tank walls only bear their 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 wall, pressing down on the tilted section and increasing the downward pressure on this portion, 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 tank walls are very thin, with weak resistance to deformation, resulting in a high risk of tipping over. Maintaining economic efficiency makes it difficult to increase rigidity, which is insufficient for applications with high safety requirements, significantly limiting its application range. Utility Model Content

[0003] This utility model provides an assembled steel plate water tank with a high-strength reinforcement device, which aims to enhance the water tank's resistance to deformation and rigidity to meet the requirements of usage scenarios with high safety requirements.

[0004] A prefabricated steel plate water tank with a high-strength reinforcement device is characterized in that: the device includes a central column, an inner tank, an outer wall, telescopic cables, and support rods;

[0005] The central column is vertically buried in a pit dug in the ground using gravel blocks. The depth of the central column is 1 / 6 of its total height. Several hooks are evenly welded around the top, upper part and bottom of the central column.

[0006] The outer wall is arranged circumferentially around the central column. The outer wall is composed of T-shaped steel, stirrups, hoops, and steel plates. The T-shaped steel is evenly and vertically arranged circumferentially, and U-shaped buckles are installed on the flanges of the T-shaped steel at both the top and bottom. The hoops are tightly attached to the T-shaped steel and bolted or anchored as a whole. The hoops are horizontally arranged close to the inner side of the T-shaped steel, with denser hoops at the bottom and sparser hoops at the top. The steel plates are arranged close to the inner side of the hoops. The steel plates, hoops, and T-shaped steel are tightly attached to the T-shaped steel and bolted or anchored as a whole. The U-shaped buckles at the top of the T-shaped steel are connected to the hooks at the top of the central column using telescopic cables.

[0007] The hoops correspond to the steel plates, and hoops must be installed at the horizontal joints of the steel plates; the stirrups correspond to the hoops and are installed on the outer center line of the hoops; closed turnbuckles are installed at both ends of the stirrups, one end of which is connected to the U-shaped buckle anchored to the web of the T-shaped steel through the closed turnbuckle, and the other end is bolted to the web of the T-shaped steel; the tightness of the stirrups is adjusted by pulling them in a straight line using closed turnbuckles.

[0008] The inner liner is fitted tightly against the inner side of the outer wall. The outer edge of the top of the inner liner is connected to the top of the outer wall. The center of the inner liner is closed and hung on the hook at the top of the central column. The top surface of the inner liner is suspended by a rope on a telescopic cable. A rainwater collection hole and an inspection port are opened on the top surface of the inner liner.

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

[0010] The struts are supported between the tops of adjacent T-shaped steel sections;

[0011] An opening is made at the center column at the bottom of the inner tank, and a flange is used to seal the connection with the center column. A sludge discharge pipe and a water intake pipe are installed at the bottom of the inner tank. The openings of the sludge discharge pipe and the water intake pipe are sealed to the inner tank through a composite water tank joint. A gate valve is installed at the pipe outlet, and a vertical pipe to prevent sludge and sand is installed at the water intake inlet.

[0012] Furthermore, the telescopic cable includes a cable and a turnbuckle, and the cable is telescopically adjusted by means of the turnbuckle.

[0013] Furthermore, the rainwater collection port has a top cover and a filter screen, and the inspection port is equipped with a zipper to control opening and closing.

[0014] Furthermore, a lightning rod is connected to the top of the central column and grounded through the column.

[0015] Furthermore, a cable is buried in the fine sand layer at the bottom of the pool. One end of the cable is connected to a U-shaped buckle bolted to the bottom wing plate of the T-shaped steel, and the other end is horizontally connected to a hook at the bottom of the central column. The tension of the cable is adjusted by the U-shaped buckle bolt.

[0016] The beneficial effects of this utility model are as follows: A central column and telescopic cables are installed, creating a suspension bridge-like system between the surrounding pool walls and the central column. This system transmits the outward pressure on the outer wall of the pool to the central column, where it cancels out horizontally. The support of the outer column connected to the outer wall strengthens the vertical rigidity of the outer wall, and the telescopic cables at the top of the central column provide upward tension, improving the vertical stability of the outer wall. The hoops and reinforcing bars enhance the compressive strength of the outer wall, the struts at the top of the pool reinforce the shape of the top opening, and the deeply embedded central column improves the pool's resistance to tilting. The closed inner tank significantly reduces the peak flow rate of leaked water in the event of localized damage, minimizing the risk of accidental damage to surrounding and downstream personnel and property.

[0017] This water tank improves the stress distribution within the tank structure and enhances its resistance to damage. With the same materials and manufacturing processes, this system allows for increased depth and optimized tank shape, achieving either increased capacity or reduced cost per unit capacity while ensuring safety. This device significantly improves the safety of the aforementioned water tank configuration, enriches its functionality, further enhances its convenience and economy, raises the upper limit of project scale, and expands its application scope. It facilitates the rapid promotion and safe use of this water tank configuration in water conservancy and municipal engineering fields. Attached Figure Description
