Abstract

The invention discloses a construction method of plastic acoustic pipe fixation, which comprises the following steps: first, connecting the plastic acoustic pipe as long as reinforcement cage with the major steel of reinforcement cage; second, connecting the roll end with the last acoustic pipe end and one end of joining member with the other end of acoustic pipe by binder; then, dragging the drilling; putting down the reinforcement cage; injecting water in the acoustic pipe; putting down the second reinforcement cage in connection with the former cage; connecting the acoustic pipe with the inner acoustic pipe of previous reinforcement cage by joining member and binder; filling the acoustic pipe with clean water until the last pipe according to the analogy; binding the roll end and the top of acoustic pipe by binder; finally, casting concrete. This method has the following characteristics: simple construction process; low strength construction for workers; low cost and so on, which can be set in the filling plastic acoustic pipe.

Description

Technical field:

[0001] The invention relates to a construction method in the field of construction, in particular to a method for installing and constructing an acoustic measuring tube used for ultrasonic detection of cast-in-place piles. Background technique:

[0002] Ultrasonic detection technology for the integrity detection of cast-in-situ piles is a method of detecting concrete components using high-frequency ultrasound (20-500KHz) as an information carrier. Because of its high frequency and short wavelength, the resolution of this method is extremely high. High, extremely sensitive to defects. The acoustic measuring tube is the channel through which the probe enters the pile body during the ultrasonic detection of the cast-in-situ pile. It is an important part of the ultrasonic detection system of the cast-in-situ pile. affect the quality of test results.

[0003] At present, the commonly used acoustic tubes include steel pipes, steel bellows, and plastic pipes. Th...
