When the second ball (24) falls onto the second puncture rod (21), the second puncture rod (21) punctures the second sealing membrane (22).

6. A pipe gallery according to claim 5, characterized in that: A magnet (27) is provided on the second slide (23), and the second ball (24) is an iron ball. The second ball (24) is attracted to the magnet (27). The attraction of the magnet (27) to the second ball (24) is less than the pushing force of the rack (26) to the second ball (24).

7. A construction process for a utility tunnel, characterized in that: Using the utility tunnel as described in any one of claims 1-6 further includes: S1: Surveying and setting out, trench excavation, and pre-casting to form the pipe gallery section (1); S2: Subbase construction, and pre-cast support plate (4) at the connection end of the pipe gallery in the subbase, install shock absorber spring (5) and damper (6) on support plate (4), connect connecting plate (7) on top of damper (6) and shock absorber spring (5), and lay waterproof layer. S3: Hoist the prefabricated pipe gallery section (1) into the trench, then install the sealing component on the connecting block (2), then connect the end of the pipe gallery section (1) to the corresponding connecting plate (7), insert the connecting block (2) on the pipe gallery section (1) into the connecting groove (3) of the adjacent pipe gallery section (1), and fix the ends of the adjacent pipe gallery sections on the same connecting plate (7). S4: Install a waterstop strip in the joint of the pipe gallery and then fill the trench.

8. The pipe gallery construction process according to claim 7, characterized in that: In S1, during trench excavation, the cross-section of the trench is excavated into a trapezoid that is wider at the top and narrower at the bottom, and the bottom width of the trench is greater than the width of the pipe gallery. Construction engineering slabs are used to support the sidewalls of the trench.
