The utility model solves the problems of the technologies described above by the following technical programs: shooting detector in a kind of base pile hole, it comprises photographing module, the fixing fixed support of photographing module, and the stube cable that connects photographing module, this photographing module comprises a plurality of cameras, centers on the hard-wired a plurality of lighting devices of each camera, and a plurality of adjustable locating supports, wherein said a plurality of adjustable locating supports are located described a plurality of camera in the horizontal direction.
This photographing module comprises a shell, six faces of this shell are made up of stainless steel and the sealing of tempering optical glass respectively, camera, lighting device and adjustable locating support are fixed on the stainless steel, and see through this transparent tempering optical glass to throwing light in the pile tube and making a video recording.
Offer plural pilot hole on the transverse bar of this adjustable locating support, the next door of each pilot hole indicates the sign that different foundation pile internal diameter numerical value are arranged.
This adjustable locating support is fixed on this shell by a location pin of passing this pilot hole.
This camera is connected to video change-over device by the video line in the stube cable, and the analog signal conversion of this camera production is digital signal and is sent to portable computer by USB interface.
Establish a pulley in the top of this base pile hole on this fixed support, this stube cable is walked around this pulley and by a digital displacement measurement mechanism depth signal is converted into electric signal and is sent to portable computer.
This camera, this digital displacement measurement mechanism and this lighting device adopt the rechargeable battery power supply.
The advantage of shooting detector is in the utility model base pile hole: adopt the high-resolution imaging technique, can reliably locate and record, thereby make detect directly perceived, can accurately detect defective locations and carry out the quantitative test of defective; Can detect multiple defect; Can detect vertical defective; Can adopt the pile tube of quick mechanical splice construction to detect; Can carry out the detection of ultra-long pile.
