Detailed Product Description：	Acoustic Pipe pile cost economy: a bridge pier in the deeper Bored high-rise building construction, pile testing requirements for filling column pile quality testing using acoustic transmission method, in accordance with the design requirements should be embedded test tube (pile based acoustic tube). Pile diameter buried 0.8m below the required two test tube, two test tube must be fixed in the steel cage along the same line. Pile diameter 0.8m-2.0m need buried three test tube, three test tube must be fixed in the steel cage isosceles triangle. 2.0m above the required buried four test tube, four square test tube must be fixed in the steel cage. Conventional requires outside diameter 50-60mm steel wall thickness of about 3.5mm, take construction site welding. This method requires a high cost in construction, complex operation, has caused great inconvenience to the construction site, the pile of the company's sound test tubes, construction costs account for only about one-third the cost of an ordinary pipe. Acoustic spiral tube diameter is preferably 50 ~ 60mm. 2 spiral Acoustic Pipe should lower end closed, the upper stamp, no foreign body inside the tube; spiral Acoustic Pipe connections should be smooth transition, the nozzle should be more than 100mm above the top of the pile, and each spiral pipe mouth Acoustic highly desirable unanimously. 3 should take appropriate method of fixing screw Acoustic Pipe, parallel to each other after making piles. 4 spiral Acoustic Pipe laying amount shall meet the following requirements: 1) D≤800mm, 2 root canal. 2) 800mm 2000mm, at least four pipe. (Where D - Design subjects pile pile diameter). 5 Acoustic Pipe spiral along the pile should be symmetrical shape of the outer section arranged in the direction of the arrow shown in figure are numbered clockwise.
