Embodiment Construction
[0020] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of the various implementations in the present invention can be combined accordingly on the premise that there is no conflict with each other.
[0021] Such as figure 1 As shown, an in-hole imaging device for detecting the integrity of prefabricated pipe piles includes a camera 1 , a depth measurement rope 7 , a support frame, a turntable 8 , a handle 9 and a frame 10 . During use, the support frame 10 is fixed above the prefabricated pipe pile, and the turntable 8 is fixed on the beam of the support frame 10 . The support frame is a device that fixes the camera and drives the camera to move up and down along the pipe wall, and its center is a circular support frame main body 2 . The top of the support frame main body 2 is detachably fixed with a connecting rod 3 , one end of the depth measuring rope 7 is ...

The invention discloses an in-hole imaging device used for detecting the integrity of a prefabricated tubular pile and a detecting method. The in-hole imaging device comprises a rotatable camera with a lighting function, a support frame and a bracket frame. The camera is fixed to the support frame, is rotatable, can illuminate and is connected with a computer through a wireless device. The support frame is provided with three freely extensible supports. The top end of each support is connected with a wheel through a spring. The bracket frame is connected with the support frame through a measuring rope. The in-hole imaging device used for detecting the integrity of the prefabricated tubular pile and the detecting method have the beneficial effects that the rotatable camera is fixed to the support frame and the depth inside the pile is adjusted through a turntable on the bracket frame, so that the defect positions of the pile are detected from different depths and different angles; and through the specially designed support frame, the imaging device can keep balance well in the tubular pile, and the adaptability of passing through obstacles inside the tubular pile is also relatively high.
Description
technical field [0001] The invention relates to the field of detection devices for construction engineering technology, in particular to an imaging device in a hole of a prefabricated pipe pile. technical background [0002] When the prefabricated pipe piles are sinking, excessive pile pressure (clamping force) will easily crush the pipe piles, or cause longitudinal cracks in the pipe piles. The low-strain reflected wave method is applied to the detection and judgment of the integrity of the prefabricated tubular pile, which brings great convenience to the quality monitoring of the pile foundation construction. It is economical and practical, but it has certain limitations and judgments. Blind areas often cause the inspectors to make conclusions inconsistent with the actual situation when judging the integrity of the pile body, and even leave hidden dangers to the safety of the project. The prefabricated pipe pile hole imaging device can be used in conjunction with the low ...
