The present invention relates to a water tank with a detachable waterproof water bag, which can be continuously assembled to be strong and convenient as a water storage capacity expansion type water bag and water tank double storage structure, which prevents inefficiency of space usage to enable increase and decrease in a water storage capacity of the water tank unlike an existing water tank wherein assembling, expanding, moving, and washing are difficult due to a structure in which the existing water tank is heavy with a large scale and has a limited capacity. The water tank with a detachable waterproof water bag has a sealing type structure capable of being completely blocked from outer air, direct light, rain, wind, and various contaminants and has an improved external appearance as the water tank can be in harmony with a building or a house. The water tank can be conveniently moved and stored by being folded after being used as the shape of the water tank can be changed when the water is not filled, by using a soft waterproof fabric such as tarpaulin, which is not torn, in a box type water tank formed of a preserved wood material. The water bag is fixed and installed inside in order for the weight thereof to be distributed so that the water bag does not sag not to receive strength from expansion and contraction, wherein the water bag can easily discharge and transfer the water and allow the water to flow inside, in a soft sack form attached to and detached from the tank. When the water tanks are connected to each other, drainage and flow of the water can be possible without blocking. So, the water tank with the waterproof water bag can be conveniently and economically assembled to save a space in desired size and shape at a desired place as necessary without restriction of an installation space by having an excellent expansion property in the horizontal or vertical direction. |
