Problems solved by technology

[0004] However, when the acoustic tube is damaged, the acoustic transducer cannot enter the acoustic tube to detect the pile foundation, which leads to the failure of the normal detection of the bridge.

Embodiment 1

[0038] Embodiment 1: as figure 1 As shown, it is a bridge pile foundation non-destructive testing device disclosed by the present invention, which includes a climbing mechanism 1 climbing along the pile foundation and a detection mechanism 2 connected with the climbing mechanism 1. The climbing mechanism 1 includes four connecting arcs arranged around the pile foundation 11. A plurality of legs 12 connected to the connection arc 11, a drive mechanism 3 for driving the legs 12 to move back and forth in opposite directions, and a controller 13 for controlling the start and stop of the drive mechanism 3, and the controller 13 is connected to the drive mechanism 3 by wires. The number of supporting legs 12 is eight, every two supporting legs 12 are slidably connected with a connecting arc 11, and the lower ends of the supporting legs 12 are connected with the side wall of the pile foundation. like figure 2As shown, the detection mechanism 2 includes two water storage tanks 21 co...

Embodiment 2

[0047] Embodiment 2: a kind of bridge pile foundation non-destructive testing method, comprises the following steps:

[0048] S1: Set the connecting arc 11 around the pile foundation and connect the adjacent connecting arcs 11, and make the lower end of the abutment plate 17 abut against the side wall of the pile foundation, surround the detection arc 41 around the pile foundation and connect the adjacent detection arcs 41 Connect the connecting rope 43 of the hoist 42 to the upper end of the detection arc 41, and inject clear water into the water storage tank and the water storage bucket 24;

[0049] S2: The controller 13 controls the motor 32 to start rotating, the climbing mechanism 1 climbs to the top of the pile foundation, and then the controller 13 controls the hoist 42 to start at intervals, driving the detection arc 41 to move upward intermittently, and the detection mechanism 2 detects the pile foundation at the same time;

[0050] S3: After the detection is complete...

Abstract

The invention relates to a nondestructive testing device and a nondestructive testing method for a bridge pile foundation. The device comprises a climbing mechanism and a detection mechanism. The climbing mechanism comprises a plurality of connecting arcs surrounding the pile foundation, a plurality of supporting legs arranged on the connecting arcs, a driving mechanism for driving the supportinglegs to reciprocate in opposite directions, and a controller for controlling the driving mechanism to start and stop. The supporting legs are in sliding connection with the connecting arcs. The detection mechanism comprises a water storage tank connected with the connecting arc end to end, sound wave transducers arranged in the water storage tank and a microcomputer connected with the sound wave transducers and used for processing data, the side, facing the pile foundation, of the water storage tank is provided with an opening, the opening of the water storage tank abuts against the side wallof the pile foundation, and the sound wave transducers are located on the two sides of the axis of the pile foundation respectively. The climbing mechanism moves to the top of the pile foundation anddrives the detection mechanism to continuously move upwards. The pile foundation is detected through the detection mechanism, a sounding pipe does not need to be used for detection in the detection process any more, and therefore the pile foundation detection process is more convenient.

Description

technical field [0001] The invention relates to bridge pile foundation detection technology, in particular to a bridge pile foundation non-destructive detection device and a non-destructive detection method. Background technique [0002] The pile foundation of the bridge is the main load-bearing part of the bridge. During the use of the bridge, when the bridge is hit or the load is too heavy, it will cause cracks inside the pile foundation, and the damage of the pile foundation is usually reflected in the interior of the pile foundation , at this time it is necessary to carry out non-destructive testing on the pile foundation of the bridge. [0003] Some pile foundation inspections usually use the acoustic tubes embedded in the equipment, place the acoustic wave transducers in the acoustic tubes, and use the sound waves to pass through the pile foundation to generate parameters to detect whether there are cracks in the pile foundation. . [0004] However, when the acoustic...
