| description | The utility model discloses a rock block roadbed air injection device which comprises an air injection pipe, one end of the air injection pipe is connected with an air source generating device, the other end of the air injection pipe is inserted into a rock block layer of a roadbed to be measured, the end head of the end, inserted into the roadbed to be measured, of the air injection pipe is closed, and an air guide hole is formed in the side wall of the air injection pipe. The gas injection pipe is used for introducing high-pressure gas into the roadbed to be detected; the device is simple in structure and low in manufacturing cost, gas is injected into the roadbed to be detected only through the gas injection pipe, the end, inserted into the roadbed to be detected, of the gas injection pipe is closed, it is guaranteed that the whole gas guide pipe is closed except the gas guide holes, and the gas in the gas injection pipe is prevented from escaping towards the bottom of the roadbed and affecting the detecti |
