本检测以可靠便利为原则，采用制作钢筋时先拼接，挂装，后下钢筋时再连接定位，与钢筋笼安装前先在底笼焊接定位（声测管底管带焊接定位扣）、上部采用铁丝捆扎，每2-3米捆扎一道。确保检测管垂直定位，利于桩基检测，并防止混凝土导管碰撞。
　　一、声测管定长
检测管长度以钢筋笼长度为准，底管应稍长于钢筋底笼20-30厘米
　　二、声测管底笼安装
检测管底管配有活动夹箍一个，按实际施工情况定位，再焊接到钢筋笼上，以固定住检测管，防止上浮和转动
　　三、声测管中笼安装
钢筋笼成型后再安装检测管中接管，检测管上点以U型钢筋活络定位，上下可以滑动，插口一端用S型钢筋挂钩定位，待钢筋笼安装时，取下S型挂钩，把检测管滑下，插入底管，然后用液压钳钳压固定，中间每隔2-3米用铁线捆扎、固定。以此类推
　　四、声测管顶笼安装
在钢筋顶笼安装完后，声测管所有接头连接完毕，确保钳压牢固，检测管内必须注满清水，最后拧上专用封头，此所有操作工艺完成
　　五、声测管在桩基为半笼安装时

This test tube with convenient and reliable for the principle, USES the production of steel when first joining together, mounted, after the reinforced connection again when positioning, and the reinforcing cage in bottom cage welding before installation location (acoustic detecting tube bottom belt welding positioning buckle), upper with wire strapping, banding together every 2 to 3 meters. Ensure the vertical positioning detection tube for pile foundation inspection, and prevent the tremie collision.
A, test tube fixed length
Test tube length will be subject to length of reinforcing cage, bottom tube reinforced bottom cage should be slightly longer than 20-30 cm
Second, the test tube bottom cage installed
Testing activities clip pipe bottom is equipped with a, according to the actual construction of positioning, welded to the steel reinforcement cage, again to hold the test tube, prevent the buoyancy and rotation
Three, test tube installed in its cage
Reinforcing cage forming again after installation in the test tube to take over, points in the test tube with adjustable positioning, U steel can slide up and down, the socket end with S type steel hook positioning, reinforcing cage when installation, remove the "S" hooks, sliding down the test tube, the bottom of the insert tube, and then use hydraulic clamp fixed clamp pressure, the intermediate every 2 to 3 meters with wire bundling, fixed. And so on
Four, test tube installed in a cage
At the top of the reinforcement cage after the installation, test tube after all joint connections, to ensure the clamp pressure, must be fresh water injection test tube, the special twist on the head, all the operation process is complete
Five and a half, test tube in the pile foundation for the cage when installation
