An Intze type overhead water tank is a water storage structure typically used for domestic, agricultural, or industrial purposes. This tank consists of two main components: a shell and a cover. The shell is a cylindrical or rectangular concrete formwork filled with concrete, while the cover is a removable section that can be placed on top of the shell to create the finished water storage vessel.
Factors to consider when designing an Intze type overhead water tank include:
Capacity: The tank needs to be sized to hold the desired volume of water, considering factors such as the expected water demand, available space, and structural requirements.
Pressure rating: The tank should be designed to withstand the maximum allowable pressure exerted by the water, taking into account the concrete mix strength and any internal or external pressure loads.
Material selection: The most common material for building the shell is concrete due to its durability and ability to withstand pressure. Other materials like steel or plastic may be used depending on the specific application and design requirements.
Foundations: The tank should be supported on a firm and stable foundation that can withstand the weight of the water and any other imposed loads.
Drainage and inspection: The tank should be equipped with proper drainage mechanisms to ensure water is drained efficiently and the interior is kept clean. Additionally, access for inspection and maintenance should be designed to ensure long-term reliability.
Seismic considerations: In areas prone to seismic activity, additional measures may be required to ensure the tank can withstand ground movement and potential overturning.
Safety and corrosion resistance: The tank should be designed to meet relevant safety standards and resist corrosion from external elements.
Examples of Intze type overhead water tanks:
Domestic water tanks with a capacity of 1000 liters.
Agricultural storage tanks for irrigation purposes, holding up to 10,000 liters.
Industrial process tanks, holding various fluids and chemicals.
Design considerations:
The shell thickness is determined by the pressure rating and the desired wall thickness.
The cover thickness depends on factors like wind resistance, thermal insulation, and ease of access.
The foundation needs to be sized to accommodate the weight of the water and any additional equipment, such as pumps or control systems.
Drainage design must be carefully engineered to ensure efficient water drainage without compromising structural integrity.
By carefully considering these factors and following established design guidelines, engineers can build safe, reliable, and durable Intze type overhead water tanks that meet specific functional requirements and safety standards
