Description

Technical Field

[0001] The utility model relates to the technical field of water tanks, in particular to a BDF composite semi-buried water tank. Background Art

[0002] With the strengthening of fire awareness, more and more corporate projects and personal projects need to add fire water supply equipment. The underground integrated fire water supply equipment consists of two parts: a water tank and a pump room. It is easy to maintain and has stable and reliable operation. It is an alternative to underground concrete water tanks. It has low cost and does not occupy ground area. It can be placed in the owner's vacant land, under green belts, and scattered vacant land. BDF board is a new type of board in the water tank industry. The name means: B is the letter of "stainless steel", D is the letter of "galvanized plate", and F is the letter of "composite". BDF board is a composite of stainless steel plate and galvanized plate. The side in contact with water is lined with stainless steel thin plate to ensure water quality and corrosion resistance. The outside is a thicker galvanized steel plate to provide overall strength and rigidity.

[0003] Underground water tanks require regular maintenance. However, existing semi-underground water tanks are generally large and tall, with maintenance access located at the top. Furthermore, because the tanks are buried in a pit, workers need to use a ladder to access the top of the tank for maintenance, which is very inconvenient. Furthermore, while some water tanks have an external iron ladder for maintenance workers to climb, the ladder is fixed to the outside of the tank and is exposed to the elements for extended periods of time. This exposure can lead to corrosion, significantly shortening the tank's service life. Therefore, there is an urgent need to design a BDF composite semi-underground water tank to address these issues. Utility Model Content
