However, in locations where the underground water level in the buried ground rises or where pressurized water is applied, the water tank becomes buoyant due to the buoyancy and pressure of the water under pressure, causing a problem in that the level within the tank changes. For this reason, conventional methods have been to increase the weight of the water tank by increasing the amount of concrete in the frame, fixing it to the bedrock layer of the ground with anchor bolts, etc., and installing water collection pipes at the bottom of the tank to improve the underground water level and pressure. They were also trying to reduce the

When a pressure equal to or higher than a set value acts on the rupture valve provided at the bottom of the water tank, the rupture valve ruptures and the groundwater around the tank is introduced into the tank. This eliminates the buoyant force and pressurized water pressure acting on the water tank, prevents the water tank from floating as an emergency measure, and prevents damage to the water tank.

。DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, a water tank 1 is formed of a concrete frame and is buried underground in a predetermined ground. An opening 2 is formed on the bottom of the water tank 1, and a valve 3 is provided on the bottom of the water tank 1 to cover the opening 2. This rupture valve 3 is removably attached to the bottom surface of the water tank 1 by means of bolts 4 at appropriate locations on the periphery thereof, and retains water-tightness at the portion that abuts on the bottom surface of the water tank 1. Further, the strength of the rupture valve 3 is set so that when the water tank 1 receives a pressure sufficient to float, the rupture valve 3 ruptures under the pressure.

A buoyant force acts on the water tank 1 due to an increase in buoyancy due to a rise in the groundwater level in the ground where the water tank 1 is buried and an increase in the pressure of the water under pressure. At this time, a pressure equal to or higher than the set value acts on the rupture valve 3 provided on the bottom of the tank 1, causing the rupture valve 3 to rupture, and the groundwater around the tank flows into the tank through the opening 2 at the bottom of the tank. As a result, the buoyant force and water pressure acting on the water tank 1 are eliminated, and the water tank is prevented from floating as an emergency measure, thereby preventing damage to the water tank.

Therefore, according to this embodiment, floating of a buried water tank used as a treatment water tank in a water and sewage plant or the like can be prevented as an emergency measure.
