Problems solved by technology

[0005] When the existing device is measuring the primary branch, because the measuring wheel and the radar system are fixed, when the measuring wheel contacts the concave lining, it cannot be well coupled with the contact surface. The distance reflected by the measurement wheel cannot represent the real measurement mileage in the actual measurement. At the same time, because the measurement wheel cannot be well coupled with the contact surface, the experimental data fed back deviates from the real situation behind the initial support, and cannot fully represent and the real situation after react-lining

Abstract

The invention discloses a ground penetrating radar in a device for measuring a primary support with a measuring wheel, comprising a ground penetrating radar and a measuring wheel, wherein a signal acquisition device is mounted on the measuring wheel, and the signal acquisition device is connected to the ground penetrating radar; the drive shaft of the measuring wheel is connected to one end of a damping hinge horizontally fixed to the top of the ground penetrating radar through a telescopic link, the other end of the damping hinge is connected to the ground penetrating radar; the telescopic link can rotate with the drive shaft; the drive shaft is also connected to the side wall of the ground penetrating radar through a horizontal elastic device; the elastic device, the telescopic link andthe ground penetrating radar form a triangle, so that the measuring wheel forms a stable system with the ground penetrating radar during the traveling process to measure; and the signal acquisition device mounted on the measuring wheel is connected to the ground penetrating radar.

Description

technical field [0001] The invention relates to tunnel engineering, in particular to a device for measuring the thickness of primary supports, the distribution of steel bars, the compactness of concrete, and the state of emptying with a ground-penetrating radar using a measuring wheel. Background technique [0002] Ground Penetrating Radar (GPR) uses frequencies between 10 6 ~10 9 Hz radio waves to determine a geophysical detection instrument for subsurface media. With the continuous development of microelectronics technology and signal processing technology, ground penetrating radar technology is widely used in many fields such as engineering geological survey, building structure survey, highway engineering quality inspection, and underground pipeline detection. [0003] The basic principle of ground penetrating radar is shown in the figure below. The transmitting antenna directs the high-frequency short-pulse electromagnetic waves into the ground, and the electromagneti...
