The Water Tank Construction Process
Our construction process of water tanks must be done properly to ensure the durability and stability. It is important that the construction process be followed according to the design documents. It is also necessary to carry out corrosion preventive procedures and install equipment, stipulated in the design.
The correct organization of welding and assembly operations is essential due to the large dimensions and long welds of tank walls. This allows to reduce residual stress caused by shrinkage of the welds to a minimum.
Circular Type
This type of water tank is often seen in residential, apartments and other communities. This tank has a circular shape and is constructed above the ground level. It can be made from a variety of materials including concrete, steel or polyethylene. Its foundation is usually a concrete slab or a layer of white sand. Its base must be solid and should not contain sharp elements.
Depending on the water tank’s size, it may require a suspension platform to ease construction. This method can reduce the use of scaffolding. The suspension platform can also be used to help with the welding process.
The balance shell courses are erected using the jacking method. The rolled plates are shifted to the tank foundation area stacked around the periphery. Jigs and fixtures are used to align the shell plates. Assembly butt joints are welded after all the other welds have been completed. The joints should be carefully inspected. This helps to reduce the residual stress resulting from weld shrinkage.
Square Type
This type of water tank is often used in elevated locations to benefit from the use of gravity forces to distribute the water. They are commonly seen in large scale commercial applications. The construction of these tanks is made from the top down. This method eliminates the need for scaffolding and high level work which increases safety and boosts productivity.
The brick masonry for the side walls of the tank should be laid while the concrete is still green to avoid leakages or cracks. This process should be completed within a week after laying the base slab.
The pipes leading to and from the water tank should be buried. This limits the strain and impact damage that can cause them to break and disrupt the tank’s plumbing system. In addition, the piping should be covered to protect it from freezing and sunlight. The piping should also be supported with construction material to limit stress on the pipeline.
Polygon Type
Any closed two-dimensional shape formed with straight lines is known as a polygon. However, a cube is not considered to be a polygon because it is three-dimensional and does not have sides. Polygons come in various shapes and sizes, depending on the number of sides and measure of angles.
There are many types of polygons, and each has its own unique properties. For example, a quadrilateral polygon has four equal sides and angles. A regular pentagon has five equal sides and angles, and a regular hexagon has six equal sides and angles. Other examples of polygons include equilateral triangles and rectangles.
If a polygon has more than twelve sides, it can be named using the Greek numerical prefixes for the number of sides followed by “-gon.” For example, a 15-sided polygon is called a hexakaidecagon. Polygons that have one or more interior angles measuring more than 180 degrees are called concave polygons. Polygons with inward and outward vertices are called convex polygons.
Polyethylene Type
Water tanks are made of steel or plastic and come in a wide range of volume capacities. They are primarily used to transport liquid throughout an area. They are available with a variety of features that assist in the regulation of fluid flow.
Plastic tanks are a great alternative to steel tanks, which require a crane to install. They are also much lighter than concrete tanks, making them easier to handle. Many plastic tanks can be moved by hand if they are empty, which is helpful for navigating challenging terrain.
Polyethylene is a versatile plastic material that can be produced in different shapes and sizes. It is made from naphtha or petroleum, which is heated to release ethylene molecules that branch out to create different polymer types. Polyethylene is known for its low moisture absorption, chemical resistance and durability. It is often used in milk cartons, detergent bottles and plastic pipes. Other uses include chute liners, bearing pads and bushings, cutting boards and machine parts.
