螺旋式声测管的使用注意事项：

　　1、留意密封圈是否完好。
　　2、螺旋必需用专用工具紧固到位。
　　3、每下放完一节钢筋笼后必需把声测管内加满净水。
　　4、下放钢筋笼时声测管接头处一定把铁丝从吊环内穿过绑在主筋上。
　　5、焊接钢筋不要把电焊钳、搭铁线接触到声测管上，以免电焊强流造成声测管破漏。
　　6、钢筋笼下放完毕把声测管内一定加满净水，最后用盖盖好、严谨管内进入混凝土或水泥浆。

When use must pay attention to the relevant matters:
1, pay attention to seal rings are in good condition.
2, spiral must tighten in place with specialized tools.
After 3, each section of reinforcing cage required the acoustic test tube filled with clean water.
4, lowering steel reinforcement cage sound when the measuring tube must be joint through the rings in the wire tie on the main reinforcement.
5 don't put the electrode holder, welding steel, a wire contact to the acoustic detecting tube, lest cause acoustic detecting welding strong flow tube broken.
6, reinforced LongXia put the completion of the measuring tube must be filled with clean water, the last with good cover, rigorous tube into the concrete or cement.
