Description

Technical Field

[0001] The present invention relates to the technical field of bearing capacity detection devices, and particularly to a highway bridge bearing capacity detection device for traffic construction. Background Art

[0002] As a key node of the traffic network, the bearing capacity of highway bridges is directly related to the safety and smoothness of transportation. With the continuous growth of traffic flow, the continuous increase in vehicle load, and the extension of the service life of bridges, it is becoming increasingly important to detect the bearing capacity of bridges in a timely and accurate manner. Traditional detection methods mainly include static load tests, dynamic load tests, and non-destructive testing.

[0003] In the prior art, a Chinese patent with the publication number CN106706239B discloses a bridge rapid load test method, which includes the following steps: establishing a finite element calculation model of the bridge; arranging displacement measuring points at key positions of the test span; driving a vehicle slowly along the bridge deck to collect the displacement influence line of the bridge; drawing the measured curve of the bridge displacement influence line; selecting the displacement measured values with high credibility according to the actual results of the displacement influence test data; establishing a multi-condition loading model according to the selected measured displacement values and the corresponding positions of the vehicle loads, and performing finite element analysis and calculation; establishing a displacement residual expression to form an objective function, and performing finite element model correction; using the corrected finite element model to calculate the deflection and strain under the load test conditions, taking the calculated values of the corrected model as the measured values, taking the calculated values of the uncorrected model as the theoretical values, calculating the verification coefficient, and evaluating the bearing capacity of the bridge according to the bridge bearing capacity assessment specification.

[0004] The test method provided by the above patent is to carry out a test on the bridge load by using the dynamic load test method. When actually detecting the bearing capacity of a bridge, it is not only necessary to use the dynamic load test method for testing, but also necessary to use the non-destructive testing method to detect the bridge piers to judge whether there are cavities, cracks, inclusions, etc. inside the piers, which will directly affect the bearing capacity of the bridge. Non-destructive testing mainly uses ultrasonic waves to detect the piers, but the existing method of using ultrasonic waves to detect the piers requires two workers to hold two ultrasonic transducers on both sides of the pier respectively, which is very wasteful of human resources. At the same time, it is impossible to accurately align the two ultrasonic transducers, affecting the measurement results. Moreover, most of the piers are relatively high, and the workers cannot detect the high places of the piers. Summary of the Invention

[0005] The purpose of the present invention is to provide a highway bridge bearing capacity detection device for traffic construction, aiming to improve the problem that the existing method of using ultrasonic waves to detect piers requires two workers to hold ultrasonic transducers against the piers, wasting human resources, having low detection efficiency, and being unable to effectively detect the high places of the piers.

[0062] Working principle: During use, assemble the entire detection device, then unfold the first splicing portion 1 and the second splicing portion 2, and then snap them onto the bridge pier. By rotating the bidirectional screw 3, the bidirectional screw 3 drives the first splicing portion 1 and the second splicing portion 2 to snap onto the bridge pier, and ensure that the first splicing portion 1 and the second splicing portion 2 are stably connected to the bridge pier. Then fix the positions between the first splicing portion 1 and the second splicing portion 2, and then the motor 5 can be controlled to rotate, so that the entire device moves up along the bridge pier to the detection point, and the coupling agent application component 9 is controlled to apply the coupling agent at the detection point. Then control the entire device to move up so that the output end of the electric push rod 7 is aligned with the bridge pier. Then control the electric push rod 7 to drive the ultrasonic transducer 8 to abut against the bridge pier, and then use the detector 10 to control the ultrasonic transducer 8 to detect the bridge pier, which is convenient to judge whether there are problems such as hollowing, impurities, and cracks inside the bridge pier; In this way, moving up and down can detect the entire bridge pier, and the detection horizontal position can also be adjusted by pulling out the mounting plate 6 by a certain length.
