1. Following the ultrasonic screening tubes are carried in the construction website, it ought to be averted to create it twisted or pressed throughout loading, handing and installing. The ultrasonic screening tube should be saved in areas with rain shade in order to avoid the rustiness in the pipe body. The ultrasonic testing tubes that happen to be planning to be mounted ought to be examined very first. People which can be twisted or deformed will not be authorized for set up method.

2. The ultrasonic testing pipe could be straight fastened around the inside with the reinforcing cage. The spacing in between the fixed factors must be under 2m. There must be fastened factors on the bottom in the ultrasonic screening tube and also the joint components. For the components the place there's no reinforcing cage, the ultrasonic testing tube could be fastened with metal brackets.

3. With regard to the repairing approach in the ultrasonic testing tube along with the reinforcing cage, metal clip is actually a priority. Following the clip is intently pressed on the ultrasonic screening tube, the clip and steel needs to be welded with each other. Technique of binding the ultrasonic testing tube as well as the reinforcing cage with the fixed position: 1st, wrap an iron wire around the steel twice. Then, braid the iron wire for 70-80mm. Individual the two iron wires and bind the ultrasonic testing tube. Very last, fasten the iron wire. (All of the binding of iron wires with the fastened stage really should adhere to this technique.) Program of clamping ultrasonic screening tube. During the installation from the ultrasonic screening tube, following the higher pipes are positioned appropriately (with 3mm of scale mark), point the rounded concave element in the particular clamping best with the convex element in the socket (or joint) using a rubber ring inside of. Press the pipes with the joint element to the shape of hexagon. Test the tightness and evaluate the size that has a gauge. When the gauge can perfectly be stuck into the shape of hexagon, it exhibits that it's been pressed restricted sufficient.

four. When we are placing the reinforcing cage into the pile holes, we must always safeguard the reinforcing cage from becoming twisted. Pipes needs to be horizontal or vertical with one another. The ultrasonic testing tube should be set up together with the reinforcing cage segment by part. In each and every part, we must always inject cleanse water in to the ultrasonic screening tube. Following the installation, the ultrasonic screening tube must be sealed by lid or cork in case that there might be dirt falling into the ultrasonic testing tube in the course of the process of concreting and blocking the passage.

five. The depth of burying the ultrasonic testing tube ought to be kept 50mm-150mm above the bottom from the piles. The very best with the ultrasonic testing tube should be kept 300mm-500mm previously mentioned the very best of the piles. The top exposed with the ultrasonic screening tube with regard to the identical pile should be exactly the same.

6. Just before casting concrete in to the piles, it truly is essential to test the h2o stage within the ultrasonic testing tube. Fill it if there is certainly not sufficient water.

7. In the event the ultrasonic screening tubes must be reduce, we must always apply cutting device and polish the mouth from the pipe very first. Welding machine can not be utilized for this work.

eight. During the welding of steel, try not to let the welding fluid be sprayed around the physique or joint from the ultrasonic screening tube.
