In this embodiment, the second guide frame 66 is fixed on the second fixing block 58, and the second guide frame 66 is wound outside the second spring 60 and the second support rod 62, so as to improve the stability of the second guide frame 66; by embedding the second guide portion 68 into the second guide frame 66, the second guide portion 68 is disposed between the second spring 60 and the second support rod 62, and the sectional area of the second guide portion 68 is larger than that of the second support rod 62, so that the second guide portion 68 can move in the second guide frame, thereby preventing the second support rod 62 from moving too far, and at the same time, the second support rod 62 can be ensured to move along a straight line, thereby ensuring the damping effect on the second pipe 16.

In an embodiment of the present invention, preferably, as shown in fig. 1 to 4, the water pipe for hydraulic engineering further includes: a second stopper 70; the two second position-limiting portions 70 are disposed on the outer side of the second tube 16, and the two second position-limiting portions 70 are attached to two sides of the second anti-vibration tube 54.
