Example 1

As shown in fig. 1, the grouting pipe integrating acoustic grouting and grouting comprises an acoustic unit 1 and a grouting unit 2, wherein the top of the acoustic unit 1 is in threaded connection with an end cover 7, the bottom of the acoustic unit is in threaded connection with a grouting head 8, and the grouting head 8 is bullet-shaped, so that the grouting pipe is conveniently inserted into a pile foundation. The grouting unit 2 is in sliding connection with the middle part of the end cover 7, so that the position of the grouting unit 2 can be conveniently adjusted. The pipe wall of the acoustic unit 1 is uniformly provided with second grouting holes 4, and the second grouting holes 4 are also provided with sealing layers 5.

As shown in fig. 2, the grouting unit 2 is disposed inside the acoustic unit 1, a first grouting hole 3 is disposed on a pipe wall of the grouting unit, the first grouting hole 3 and a second grouting hole 4 are connected through a communicating pipe 6, and the communicating pipe 6 is inclined to a horizontal plane, so that when cement slurry is injected, an impulsive force is formed inside the grouting unit 2, so that a sealing layer 5 above the second grouting hole 4 is conveniently broken, and grouting is performed.

In the grouting pipe integrating acoustic detection and grouting, the sealing layer 5 is covered above the second grouting holes 4, the material of the grouting pipe is mainly sealant, and the sealing layer 5 is used for sealing the second grouting holes 4 above the side wall of the acoustic detection unit 1, so that the acoustic detection unit 1 meets the sealing requirement, the sealing performance of the acoustic detection unit 1 is good in the acoustic detection process, the second grouting holes 4 are prevented from leaking, and the smooth detection is ensured. In the construction process, the sound wave detection of the sound detection unit 1 can be firstly performed, so that the construction condition can be judged.
