    • PURPOSE:To enable the temperature of road surface to be regulated by a method in which a heat-storing water tank having a heat insulating property for winter season and a heat-storing water tank for summer season are provided, and hot water or cold water from the water tank for winter or summer season is sent into a pipe buried in the roadbed. CONSTITUTION:A heat-storing water tank 1 having a heat-insulating property for winter season and a heat-storing water tank 2 for summer season are provided. A pipe 4 whose one end is connected to the tank 1 and the other end is connected to the tank 2 is buried in the roadbed 5, and water supply pumps 41 and 41' are provided to the way of the pipe 4. In the summer season, the pump 41 is actuated to send cold water 21 in the tank 2 to the pipe 4 to move it into the tank 1, where it absorbs heat from the roadbed 5 to store hot water 11 in the tank 1. In winter season, the pump 41' is actuated to hot water 11 in the tank 1 to the pipe 4 to move it into the tank 2, where the roadbed 5 is heated and cold water is stored into the tank 2.

    • PURPOSE:To continuously separate and remove the scale components in a pressure liquid and to effectively utilize the terrestrial heat resources by sticking the scale components in the pressure liquid to suspending bodies and bringing the suspending bodies into colliding contact with the other suspending bodies and the inside surface of a device by the kinertic energy of the pressure liquid, thereby exfoliating and dropping the deposits thereof. CONSTITUTION:The pressure liquid 2 such as terrestrial hot water or hot spring water is ejected in a device body 1 and is separated to gas 6 and liquid (hot water) 4. The gas 6 is discharged from a discharge pipe 7 and the liquid 4 is discharged from an outflow pipe 5. The scale components such as CaCO3 deposited at the time of this sepn. stick to the inside surface of the device body 1, the surface of a falling preventive body 12 and the surfaces of the suspending bodies 11 in the device body 1. The suspending bodies 11 are lowered by the kinetic energy of the pressure liquid introduced into the device body while said bodies suspend in the liquid 2. The suspending bodies come into contact or collision with or against the inside surface of the device body 1, the falling preventive body 12 and the other suspending bodies 11, etc., during falling. The scale components sticking to the bodies 11 are stripped and dropped by this contact or collision and are settled in a discharge port 8. The scale components are discharged from the port 8.

    • PURPOSE:To make it possible to simply form a heat reserving layer even for a hot spring well constructed already by inserting a heat reserving cylinder provided with high water absorbable resin arranged on its outer peripheral surface into a casing for forming a heat reserving layer with resin between the casing and the heat reserving cylinder. CONSTITUTION:Being inserted from the upper part of an upper casing 2, a heat reserving cylinder 5 sinks into hot water inside a casing 1 until the bottom end of the heat reserving cylinder 5 abuts on a connecting ring 4, the heat reserving cylinder 5 generates a clearance between the upper casing 2 and itself, and becomes in a state of soaked into the hot water in the casing 1. Then, a high water absorbable resin layer made to stick to the outer periph eral surface of the heat reserving cylinder 5 comes in contact with hot spring hot water, this high water absorbable resin absorbs water to expand, increases its volume, the outer peripheral surface of the high water absorbable resin layer reaches the inner wall of the upper casing 2, and a heat reserving layer 6B is formed by filling up the clearance between both with the high water absorbable resin layer containing hot water. Therefore, it is possible to simply form the heat reserving layer 6B, and it is possible to simply form the heat reserving layer 6B even for a hot spring well already constructed and having no heat reserving layer 6B.
