[0021] There are multiple retractable catheter structures; the spacing between adjacent retractable catheter structures is 10-100 cm, specifically 10 cm, 30 cm, 50 cm, 70 cm and 100 cm; preferably, the spacing between adjacent retractable catheter structures is 50 cm.

[0022] The sliding tube is provided with lubricating oil 4, which can be specifically butter or butter.

[0023] The sliding tube is a steel tube; the outer diameter of the steel tube is 30-60 mm, and the wall thickness is 1-5 mm, specifically, the outer diameter can be 30 mm, the wall thickness can be 1 mm; the outer diameter can be 60 mm, and the wall thickness can be 5 mm, which can be adjusted as needed. Specifically, in this embodiment, the outer diameter is 48 mm and the wall thickness is 3 mm for exemplary description.

[0024] The movable tube is a round steel; the diameter of the round steel is smaller than the inner diameter of the sliding tube; the diameter of the round steel is 20-50 mm; specifically, it can be 10 mm, 30 mm, 50 mm, etc., preferably 40 mm for exemplary description.

[0025] The tunnel side wall is provided with side wall main reinforcement 7, side wall steel edge water stop strip 5 and water stop strip fixing reinforcement 6.

[0026] As one embodiment of the present application, the specific implementation process is: during the reinforcement binding of the first tunnel side wall 1, the sliding pipe 2 (steel pipe) is embedded synchronously. (outer diameter) × 3mm (wall thickness), arranged at a vertical spacing of 50cm; after the sliding tube 2 is installed, fill it with lubricating oil 4 (butter), and make a hole in the template to insert the sliding tube 2 (steel pipe) (outer diameter) × 3mm (wall thickness)) exposed at least 5cm; after everything is ready, pour the tunnel side wall concrete 8.
