A three-way joint with screws is arranged on an end portion of an inlet-outlet water pipe which is pre-embedded in large-size concrete, and a water stopping and heat insulating ring is inserted in the three-way joint so as to guarantee that an internally-inserted digital temperature sensor can be safely inserted in. A hollow screw pin and the temperature sensor are screwed in the three-way joint so that the hollow screw pin can generate sufficient pressure on the water stopping and heat insulation ring and leakage can not happen under water pressure. A probe of temperature sensor is exactly arranged at the center of a three-way joint water pipe. The temperature detecting range of the internally-inserted temperature sensor is from -10 DEG C to 60 DEG C. The accuracy within a working range is from -0.3 DEG C to 0.3 DEG C. After being subjected to heat insulation treatment with the pipe wall, the temperature measuring device can eliminate interference of the outside temperature on temperature measuring, accurately measure water temperature at an inlet and an outlet, and accurately forecast internal heat exchange volume of the large size concrete.
