Problems solved by technology

Geological radar can reflect the existence of hidden dangers in the roadbed to a certain extent, but its exploration depth is very limited; in addition, since geological radar is a kind of equipment of electromagnetic waves, the detection in densely reinforced concrete structures suffers from severe interference, and sometimes it cannot be competent for detection tasks
Elastic wave exploration such as surface wave or seismic exploration can provide wave velocity parameters related to the mechanical properties of the detected medium structure, but usually the sensor can only be moved and fixed point by point manually. When implementing seismic exploration or nondestructive testing record acquisition, the measurement efficiency And the degree of automation is low, not suitable for field engineering requirements

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0030] see figure 1 and Figure 4 , the sensor 1 is a single-component sensor, and the sensor 1 is installed and fixed on the axle 4 of the scroll wheel 2. During the rotation and rolling of the scroll wheel 2, the axle 4 is relatively fixed to ensure the coupling direction of the sensor 1; when the sensor 1 is a piezoelectric sensor, etc. When the individual sensor is small, it can be directly installed on the axle 4, such as figure 1 As shown, when the sensor 1 is a relatively large sensor such as a magnetoelectric sensor, it can be bridged and fixed on the axle 4 of the scroll wheel 2 through the support arm 20 . The sensor 1 is coupled with the running medium surface through the axle surface 3 , and transmits the vibration signal to the sensor 1 installed on the roller 4 . The output signal of the sensor 1 is connected with the vibration...

Abstract

The invention discloses a rolling type motion sensor device and a using method thereof. A sensor (1) is fixedly mounted on the wheel axle (4) of a rolling wheel (2), points to the coupling direction, and moves on a medium surface together with the rolling wheel (2); and the sensor is indirectly coupled with the medium surface, on which the sensor (1) moves, through a wheel axle surface (3), so that a seismic signal can be transmitted to the sensor mounted and coupled onto the wheel axle (4). A seismic source (13) and the rolling wheel (2) continues moving forward at the same time; a seismic signal collecting instrument (7) is used for completing the sequent collection of the seismic exploration records of the medium surface; the sequentially-collected seismic exploration records form a seismic arrangement; and the seismic arrangement is used for exploring and recognizing the potential hazards (12) below the rolling medium surface. The sensor maintains the sensor mounting and coupling direction during moving, realizes sequent collection of the seismic signals during rolling forward, is a key component suitable for continuous detections for potential hazards (12) of a roadbed or concrete structure quality.

Description

technical field [0001] The invention relates to a rolling motion sensor device and its use method, which belongs to seismic exploration or non-destructive testing in geophysical exploration and engineering survey, and is applied to the investigation of engineering hidden dangers and defects in relatively flat surface media, especially various reinforced concrete components Or the detection of hidden dangers such as holes and cracks that have been formed or are about to be formed under road and railway subgrades. technical background [0002] In the completion acceptance of reinforced concrete slabs, beams, columns, and urban streets, highways, and railway subgrades, as well as post-maintenance and operation, the detection and evaluation of hidden dangers under the reinforced concrete surface are related to the use safety and operating life of similar structures, and are widely accepted by the engineering community. Pay attention to. [0003] The geophysical methods used in ...
