Abstract

The invention discloses an ultrasonic detection device for detecting a cast-in-place concrete pile, and relates to the technical field of construction detection. The ultrasonic detection device is mainly used for solving the problem that one-sided detection of the inherent depth of the cast-in-place concrete pile leads to inaccuracy. The ultrasonic detection device comprises two sounding pipes pre-buried in the cast-in-place concrete pile, two lead-in rods capable of being led into the sounding pipes, and a rack body for installing the lead-in rods; the bottom end of each lead-in rod is provided with an ultrasonic transreceiver, and the upper and lower ends of each ultrasonic transreceiver are provided with clamping plates; the rack body comprises a stand and a transverse hanger rod for fixing the top ends of the lead-in rods, and a vertical rod frame is fixed to the upper end of the stand and connected with the transverse hanger rod through a lifting mechanism; and the lifting mechanism comprises a lifting screw rod installed on the vertical rod frame, and the lifting screw rod is sleeved with a spiral sliding base. The ultrasonic detection device is simple in structure and high in practicality; different depths of the cast-in-place concrete pile are detected, and the detection result is accurate; and the whole structure is convenient to disassemble and carry.

Description

technical field [0001] The invention relates to the technical field of building detection, in particular to an ultrasonic detection device for detecting concrete pouring piles. Background technique [0002] Acoustic transmission method refers to the method of transmitting and receiving sound waves between the pre-embedded acoustic measuring tubes, and detecting the integrity of the pile body by measuring the relative changes of acoustic parameters such as sound time, frequency and amplitude attenuation of the sound waves propagating in the concrete medium. Pre-buried two or more acoustic measuring tubes in the pile, filled the tubes with clean water, and placed the transmitting and receiving transducers in the two tubes respectively. During the detection, the ultrasonic wave starts from the transmitting transducer and penetrates the concrete between the two pipes and is received by the receiving transducer. The actual effective detection range is the area swept by the sound ...
