A material receiving component is connected to the valve port of the valve 13; the output data of the pressure sensor 11 can be received by an external computer.

[0033] In actual use of grout, the grout is used as needed, making it difficult for workers to accurately determine its usage, observe the grout content in the tank, and monitor the amount of grout added each time. Furthermore, it cannot promptly reflect the unit consumption, increasing the difficulty of engineering data statistics. To address these issues, this embodiment of the invention incorporates a pressure sensor 11. During use, the tank 12 is placed on the pressure-bearing surface of the pressure sensor 11, and then grout is added to or removed from the tank 12 via the valve 13 and the receiving assembly. The output data of the pressure sensor 11 can be received by an external computer. Therefore, workers only need to compare the difference in mass of the tank 12 before and after the change to determine the amount of grout flowing out or entering, and also the grout content within the tank 12. This reflects the unit consumption during construction and reduces the difficulty of engineering data statistics.
