Acoustic Pipe a spiral features: easy operation, excellent sealing, strong tensile strength, anti-torque force strong, anti-vibration, no leakage, no distortion, no pipe blockage. Two:? Install and use: a lowermost section of the reinforcement cage acoustic pipe installation: the A tube (bottom tube with plug) on ??the ground inspection seal is intact, then B A tube is inserted into the tube until it is inserted A date at the bottom of the tube, then tighten the screw can be. Good then the acoustic tube into the steel cage, fastened on a predetermined size of reinforcement steel cage, no steel cage for the site, acoustic tube steel bracket available or three main steel reinforcement, bundling distance shall not exceed two m. Section 2 steel cage, steel cage and the top of the third quarter section of the reinforcement cage acoustic pipe installation:? The different lengths in different acoustic tube length steel cage (length and acoustic tube steel cage corresponding to the length). A tube is inserted by B pipe installation methods, attention seals intact. Then with wire acoustic tube through the rings on the acoustic tube installed in the steel cage hanging not too tight to be able to move up and down. ? 3 delegated to the borehole acoustic steel cage pipe installation methods: the first (most in the next section) after drilling down into the steel cage, should fill with water within the acoustic tube. Section II then welded steel cage. ? Welding is completed?, The top acoustic tube inserted into the socket end hand hold the following acoustic tube with screw fastening can, then decentralization steel cage every two meters of wire required in the acoustic tube steel banding reinforcement cage, complete decentralization of Section steel cage inside the acoustic tube filled with water. And other top section steel cage after decentralization, some of the inner tube filled with water, and finally with the lid closed. Three considerations:? 1 Note seal is intact. 2 spiral must be fastened in place with a special tool. 3 decentralization steel cage Acoustic Pipe joints must pass through the wire from the rings tied to the main reinforcement. Must fill with water within the acoustic tube 4 per decentralization End section steel cage. 5 Do not weld steel welding clamp, grounding line contact to the acoustic tube, so as to avoid leaking pipe welding strong acoustic streaming. 6 finished steel cage delegated to certain Gannes acoustic tube filled with water, cover with a lid and finally, within strict pipe into concrete or grout.
