AUTOMATIC HOT-WATER SUPPLY DEVICE FOR GROUTING WORK, FOR STEPS OF AUTOMATICALLY SUPPLYING WATER TO WATER TANK, HEATING WATER IN WATER TANK, AND SUPPLYING HOT WATER TO STIRRER

摘要

PURPOSE: An automatic hot-water supply device for grouting work is provided to optimize the temperature of a grouting liquid injected from a grouting device by automatically supplying water to a water tank, heating the water, and supplying the water to a stirrer. CONSTITUTION: An automatic hot-water supply device for grouting work is arranged between a water supply pump and a stirrer. The automatic hot-water supply device heats cold water supplied from the water supply pump and supplies hot water to the stirrer. A water tank(13), a boiler(15), and a fuel tank(17) are arranged to a support frame(11). Cold water of an external source(21) of cold-water supply is supplied to the water tank by a water supply pump(23). The cold water stored in the water tank is supplied to the boiler through a lower circulation pipe(25). The hot water heated in the boiler is supplied to the water tank through an upper circulation pipe(27). A drainage pump(31) is built in the water tank and the hot water of the water tank is supplied to the stirrer by the drainage pump. A circulation pump(33) is mounted to the lower circulation pipe. The operation of the water supply pump, the drainage pump, the circulation pump, and the boiler is controlled by a control unit.
