Bottomless rectangular tank

Bottomless rectangular storage tanks are rare; most tanks have some form of bottom support structure. However, given that you plan to use a concrete foundation and ceramic splices, this design is feasible to a certain extent. First, ensure that the design of the concrete foundation is sturdy enough to withstand all the weights and pressures associated with the size of the tank and the materials stored in it. You need to take into account soil conditions, seismic effects (if any), and other factors that may affect the structural stability. Secondly, it is recommended to seek a professional design company to carry out the specific design and calculations, to ensure the safety and stability of the entire structure. They can provide detailed design plans and construction recommendations based on the actual situation. .

Multiple factors need to be considered in the bottom design of bottomless rectangular storage tanks. Firstly, if the tank is placed on a flat, solid, and leak-proof foundation such as a concrete foundation, it is necessary to accurately measure the dimensions of the foundation so that the bottom of the tank fits perfectly on it. Additionally, reinforcement structures should be installed at the edges of the tank’s bottom, such as using angle steel, in order to distribute the weight of the tank and prevent deformation at those edges. If it is placed on an uneven surface such as the ground, a fake bottom can be designed. The false bottom can be made by assembling corrosion-resistant materials such as HDPE plastic sheets, which can be sealed to each other either by welding or with sealant to prevent liquid leakage. Additionally, a framed false bottom can be used, consisting of a metal frame combined with an anti-corrosion filter screen; this approach facilitates the removal of impurities and sediment. Determining the height of the false bottom requires considering multiple factors. First, consider the space available for sediment accumulation. If the liquid stored contains a high amount of impurities and sediment, the false bottom needs to have sufficient space to accommodate these substances, preventing the sediment from coming into contact with the actual bottom outlet of the tank; generally, at least 10–30 centimeters of height is reserved for the accumulation of sediment. Second, the method of liquid extraction needs to be considered. If liquid is to be drawn from the bottom, the height of the artificial bottom must ensure that the liquid extraction port can function properly even at the lowest liquid level, without drawing in sediment. This requirement depends on the location and size of the extraction port; generally, the artificial bottom should be at least 5–10 centimeters below the bottom of the extraction port. Third is to consider the convenience of maintenance and cleaning. A sufficient height for the false bottom allows workers to enter beneath it for inspection, maintenance, and cleaning. Typically, the false bottom is at a height from the ground or foundation that enables people to crouch or crawl underneath, with a height of around 60–80 centimeters.

You can look for sedimentation tanks; some of these are rectangular storage tanks without a bottom
