Description
[ field of technology ]
The invention relates to the technical field of ultrasonic detection auxiliary devices, in particular to a concrete filled steel tube ultrasonic detection support.
[ background Art ]
Ultrasonic detection is an important method for nondestructive detection of concrete pouring quality in a steel tube concrete arch bridge tube. The transmission loss of the ultrasonic wave in the solid is small, the detection depth is large, the ultrasonic wave can reflect, refract and the like on a heterogeneous interface, and particularly the ultrasonic wave cannot pass through a gas-solid interface. Therefore, when the concrete in the pipe has the defects of non-compactness, void, debonding and the like (the defects have gas), the concrete can be judged by parameters such as ultrasonic wave speed, waveform and the like.
Generally, when the steel tube concrete arch bridge segments are hoisted, a hanging basket is arranged between the two segments so as to provide an operation space for workers to weld the steel tubes. The ultrasonic test needs to be carried out point by point along the circumference of the steel pipe, so that the test points can be arranged only at the place where the hanging basket is arranged. After the arch bridge is closed, concrete in the pipe is poured, and the first ultrasonic detection is generally carried out three days after pouring. Each detection cross section is generally provided with a plurality of detection points, during detection, an ultrasonic transmitting transducer is arranged on the detection point, a receiving transducer is arranged at a position opposite to 180 degrees, and the detection point is changed to the next detection point until the section of the whole steel pipe is detected. Therefore, when detecting, a detector must climb up the arch bridge and go down to the hanging basket, the two persons are matched with the radial placement transducer of the steel pipe, and the other person operates the instrument. After one section is measured, the next section is changed to be detected until all sections are tested. In-pipe concrete testing is performed by age after concrete pouring, typically 3 days, 7 days, 14 days, 28 days, 56 days, and even long-term monitoring.
However, in-pipe concrete ultrasonic testing relies heavily on hanging baskets, with the following disadvantages:
1. operational risk: the hanging basket is a temporary facility, the stability is poor, a detector needs to climb down the hanging basket platform to fix the transducer, and the operation is carried out in the air, so that the hanging basket is very dangerous.
2. The detection area is limited: the hanging basket is usually arranged at the position of the flange plate in the middle of the two arch rib sections, so that ultrasonic detection can only detect the position of the flange plate, other sections can not be detected, and the detection position is severely limited.
3. The detection time is limited: the hanging basket is a temporary facility, the hanging basket can be gradually removed after the arch bridge is folded, and ultrasonic detection cannot be carried out after the hanging basket is removed.
4. The detection precision is low, and the working efficiency is low: the measuring point is required to be aligned manually, the transducer is pressed, so that the transducer is kept in close contact with the steel pipe, at least three persons are needed for detection (one person is required to operate one transducer and one person is required to operate a host computer), and the detection method has low working efficiency. In the limited platform space, the detector must continuously adjust the posture and keep the posture, and the physical strength of the detector is severely tested.
Based on the above shortcomings, a supporting device is urgently needed for ultrasonic detection of concrete in a pipe. The equipment can overcome the defect of detecting by depending on the hanging basket, simultaneously meets the requirements of light weight, portability and easy operation, improves the automation degree of the detection process, and lightens the burden of detection personnel.
