Through adopting above-mentioned technical scheme, the existence of thickening ring can improve the rigidity of knocking the pipe on the one hand to improve the effect that knocks pipe self life-span, on the other hand thickening ring sets up at the inside wall of knocking the pipe, can not increase the diameter of knocking the pipe, thereby conveniently strike the pipe at the installation of staving.

Further, both ends of the length direction of the thickening ring are arranged at a flat angle.

By adopting the technical scheme, the diameter of the thickening ring is reduced to a certain extent by the inverted angle thickening ring, so that the effect of facilitating operators to plug the thickening ring into the knocking pipe is achieved.

Further, a welding groove is formed between one end of the thickening ring, which is far away from the inner pipe, and the inner side wall of the knocking pipe.

Through adopting above-mentioned technical scheme, the welding area of knocking pipe and thickening ring can be provided to the welding groove to play the effect that improves thickening ring and knocking pipe and practice the level stability.

Further, the inner side wall of the material leakage hole is obliquely arranged.

Through adopting above-mentioned technical scheme, the drain hole lateral wall is the slope setting, will lead to the drain hole to be close to the one end that the thickening intra-annular lateral wall is greater than the drain hole and be close to the one end of thickening intra-annular lateral wall to play the effect that improves drain hole leakage speed.

In summary, the beneficial technical effects of the utility model are as follows:

1. the protection cylinder and the leakage hole are adopted, so that the effect of prolonging the service life of the inner pipe is achieved;

2. the knocking pipe is adopted, so that the effect of prolonging the service life of the protection cylinder is achieved;

3. the thickening ring is adopted, so that the effect of prolonging the service life of the knocking pipe is achieved.
