Nondestructive measurement method for concrete conveying pressure in conveying pipe

The invention discloses a nondestructive measurement method for the concrete conveying pressure in a conveying pipe. The nondestructive measurement method comprises the following steps: step 1, establishing a mathematical relationship between a concrete conveying pressure and a circumferential deformation of a pump pipe; and step 2, calculating a concrete pumping pressure at any position by measuring the circumferential deformation of the position on the pump pipe. According to the method, the circumferential deformation of the pump pipe at a discharge port of the concrete pump is measured andfitting is carried out on the circumferential deformation and the concrete pressure at the pump pipe to obtain the mathematical relationship between the concrete pressure in the pump pipe and the circumferential deformation of the pump pipe; and then the circumferential deformation measured at any measuring point on the conveying pump pipe is substituted into the mathematical relationship to obtain the concrete conveying
