Electromagnetic wave device for detecting pile diameter of all-dimensional high-pressure jet grouting pile and detection method
The invention discloses an electromagnetic wave device for detecting the pile diameter of an omnibearing high-pressure jet grouting pile and a detection method. The electromagnetic wave device comprises an antenna probe tube provided with a directional dipole receiving and transmitting antenna in four directions, a water sensor, an electric wire coil, a fixed pulley, an electromagnetic wave data acquisition instrument and an electromagnetic wave data processing and analyzing system. According to the invention, during detection, the antenna probe is set to the set drilling depth along the set angle, and the angle deviation of the antenna probe in the drilling hole is observed; the directional dipole transmit-receive antennas in the four directions transmit electromagnetic waves to different directions, when the electromagnetic waves are in contact with the interface of the jet grouting pile and the soil body, reflection echoes are generated, and the directional dipole transmit-receive antennas in the four directions receive reflection signals from different directions; and according to the fact that an image boundary shown by electromagnetic waves in different media due to dielectric constant differences is a pile-soil interface, continuous pile diameter data of the all-dimensional high-pressure jet grouting pile at different depths are calculated and obtained. The pile diameter measuring precision is improved, and the technical problem that a traditional measuring method is large in error is solved.
