The patent discloses a wall-penetrating pipe for construction engineering, which includes a mother plate, a connecting plate, a limit groove, a clamping block and a sub-plate. The outer wall of the mother plate is rotatably connected with a connecting plate, the top of the connecting plate is provided with a limit groove, the bottom is fixedly connected with a clamping block, and one side of the sub-plate is provided with a plate groove, which is adapted to the connecting plate. The design of this wall-penetrating pipe enables the mother plate and the sub-plate to be conveniently docked together through the connecting plate and the plate groove to form a preliminary connection structure. Then, the connecting plate is fixed by a fixing plate, so that the sub-plate and the mother plate are pre-assembled together, so that the situation after the connecting pipe is inserted into the wall can be tested. If there is a deviation, the sub-plate and the mother plate can be quickly separated for adjustment. This design improves the installation efficiency and convenience of the wall-penetrating pipe in the construction project, making the connection and adjustment of the wall-penetrating pipe more convenient and quick. At the same time, this design also has certain adaptability, and the sub-plate and the mother plate can be adjusted and replaced according to actual needs, thereby improving the flexibility and maintainability of the wall-penetrating pipe.
