Acoustic pipe the minds of customers and GB gap

Acoustic pipe market is specially applied in the ultrasonic detection system is reliable, perfusion pile ultrasonic detection probe into the pile internal channel. He is a bored pile ultrasonic detection system the important constituent, its in pile internal embedded mode and cross section layout, directly influence the detection results. So it is necessary to detect mount in the design should be acoustic pipe layout and embedded marking the way in construction drawings, should strictly control the quality of pre buried.

Acoustic pipe advantages:

1100% factory quality control, safe and reliable

2 is not required for construction site accident preparations

3from the construction of environment and weather condition influence

4do not need equipment investment

5save loss (which can provide fixed length pipe )

6simple and quick installation

The acoustic pipe is directly fixed to the reinforcement cage inside the frame, fixed by welding or binding, the pipe should be maintained between essentially parallel, if the detection result of the detection point of the strength of concrete is evaluated, not parallel degree should be controlled below 1 per thousand. Steel reinforcement cage into the hole should be to prevent the distortion Zhuangshi.

The acoustic pipe is usually installed with the reinforcement cage section, each section of the joint between the threaded sleeve or cannula welding connection. But no matter what the use of joint programmes must be guaranteed at high hydrostatic pressure without leakage, interface internal should be kept smooth, without welding slag, burr convex bodies, ensuring the detection probe moving. At the same time sound test tube bottom should be sealed, installed after the application of the rubber cover will pipe mouth sealing, so as to avoid foreign matter into the acoustic pipe caused by internal pore blockage.

Pile depth m acoustic pipe wall thickness mm

<501.050~701.270~901.590~1201.8

The customer may be asked to GB acoustic pipe standard is the outside diameter50mm, wall thickness to reach 3.5mm, but in the practical engineering the construction of bridge is often used in50*1.-1.5acoustic pipe. With our so many years of experience and an engineering, pile foundation within 70 meters in depth, with 50*1.-1.5fully meet the requirements of engineering, sound test tube is not be crushed; in the sound test tube is used to discharge detector,3.5mm is too thick to detector role.
