Tongliao 50 Acoustic Pipe factory stock of the test tube to facilitate reliable principle, the use of the first production of rebar splicing, mounting, when reinforced after the connection location, and the reinforcement cage is installed in the bottom of the cage welded into the first position, the upper part of the wire bundle Each bundle a 2-3 meters. Ensure the test tube is positioned vertically, which will help pile testing, and to prevent the concrete conduit collisions. First, Tongliao 50 acoustic tube test tube test tube length to fixed-length reinforcement cage length prevail, bottom pipe should be slightly longer than 20-30 cm steel cage bottom two, Tongliao 50 acoustic tube test tube test tube bottom end of the cage to install pipe with there is an active clamp, according to the actual location of the construction, and then welded to the steel cage to hold the test tube, to prevent floating and rotating three, Tongliao 50 acoustic tube test tube in the cage reinforcement cage installed before installing molding in test tube takeover, the detection point on the tube with a U-shaped reinforced active position, can slide up and down, side jack S-type steel hook position, to be installed steel cage, remove the S-shaped hook, the test tube slide, insert the end of the tube, and then use wrench to tighten the nut in the middle every 2-3 meters tied with wire, fixed. So four, Tongliao 50 acoustic tube test tube mounted in the top of the cage after cage of reinforced roof installation, test tube fittings all finished, make sure to tighten firmly, must be filled with water in the test tube, screw on the final head, this all operations process is completed five, Tongliao 50 acoustic tube test tube in a pile of half-cage installation test tube welding position can be segmented according to the actual situation, to facilitate steel hoop position, the situation in the absence of reinforcement cage can also be installed with other connectors Compared can save three bars, convenient and secure acoustic tube Xiao Zhou
