Concrete spraying equipment |
| abstract |
[57] [Abstract] [Problem] To prevent backflow of pressed concrete into a concrete quick-setting agent pumping path, and to prevent leakage of a concrete quick-setting agent into a concrete pressing agent path, and to generate concrete adhering material inside the pressing agent path. Provided is a concrete spraying device having a simple structure that exhibits good pumping efficiency and proper mixing of concrete and a concrete quick-setting admixture without causing any problems. SOLUTION: A connecting member 15 is provided with a valve body 14 made of an elastic body having an appropriate thickness d. And a slit S penetrating in the thickness direction for opening the valve when deformed in the pressure feeding direction and closing the valve when restored. |
