1. After the ultrasonic screening tubes are carried
2. The ultrasonic testing pipe may be immediately fixed within the inside from the reinforcing cage. The spacing among the fastened points ought to be under 2m. There should be fastened factors with the bottom from the ultrasonic screening tube and the joint components. Regarding the components exactly where there is no reinforcing cage, the ultrasonic testing tube might be mounted with metal brackets.
3. Intended for the fixing technique with the ultrasonic testing tube as well as the reinforcing cage, metal clip can be a priority. After the clip is closely pressed within the ultrasonic screening tube, the clip and metal ought to be welded jointly. Technique of binding the ultrasonic testing tube as well as the reinforcing cage in the fixed level: Very first, wrap an iron wire within the metal twice. Then, braid the iron wire regarding 70-80mm. Separate the 2 iron wires and bind the ultrasonic screening tube. Last, fasten the iron wire. (All the binding of iron wires at the fixed position must comply with this technique.) Software of clamping ultrasonic screening tube. Through the installation with the ultrasonic screening tube, after the upper pipes are placed correctly (with 3mm of scale mark), stage the rounded concave component from the special clamping best at the convex part in the socket (or joint) with a rubber ring inside. Press the pipes on the joint element into your shape of hexagon. Verify the tightness and evaluate the size having a gauge. If the gauge can completely be caught into your shape of hexagon, it reveals that it's been pressed restricted adequate.
four. After we are putting the reinforcing cage into your pile holes, we must always shield the reinforcing cage from getting twisted. Pipes ought to be horizontal or vertical with one another. The ultrasonic testing tube must be mounted with the reinforcing cage area by part. In every part, we must always inject clear drinking water into the ultrasonic testing tube. Following the set up, the ultrasonic screening tube should be sealed by lid or cork just in case that there might be dust falling into the ultrasonic testing tube throughout the process of concreting and blocking the passage.
five. The depth of burying the ultrasonic screening tube should be stored 50mm-150mm previously mentioned the bottom with the piles. The very best from the ultrasonic screening tube should be held 300mm-500mm above the very best of the piles. The height uncovered of the ultrasonic screening tube with regard to the exact same pile needs to be exactly the same.
6. Prior to casting concrete to the piles, it really is essential to check the drinking water stage in the ultrasonic screening tube. Fill it if there is certainly not ample water.
7. When the ultrasonic screening tubes should be cut, we should implement cutting machine and polish the mouth in the pipe 1st. Welding machine cannot be utilised intended for this perform.
8. Through the welding of steel, consider not to permit the welding fluid be sprayed around the body or joint in the ultrasonic testing tube.
