This results in the quality of the pipes used being relatively large. When installing and pre-buried, fixing devices are often required to assist. Existing water conservancy and hydropower buried pipe fixing devices, such as a new type of fixing device for water conservancy and hydropower buried pipes disclosed in application number CN202420506368.4, clamps the pipes through telescopic parts, movable frames, movable splints, etc., to achieve the clamping and fixing functions of the pipes, facilitate the burial and fixation of the pipes, and are suitable for pipe burial work in water conservancy and hydropower construction.

[0003] However, in actual use, the width of the excavated foundation pit varies according to the size of the buried pipes on site. The structure of the buried pipe fixing device in the existing technology is fixed, and it is inconvenient to flexibly adjust the span according to the width of the foundation pit. Once the width of the foundation pit is larger, it cannot be used. In addition, the existing buried pipe fixing device has a small lifting and retracting function when in use. It is necessary to first clamp the pipeline on the ground and then move it from the end of the foundation pit to the buried position. The operation is complicated and inefficient. For this reason, we propose a water conservancy and hydropower buried pipe fixing device to solve the above problems. Utility Model Content

[0024] In order to adjust the overall span and meet the needs of foundation pits of different widths, the span adjustment mechanism 4 includes a guide rod 13 and a guide rod 2 14.
