[0002] Reinforced concrete pipe jacking is a construction method for laying pipelines underground. It mainly uses precast reinforced concrete pipes as pipelines. During the construction process, it is necessary to first excavate a working well and put the precast reinforced concrete pipe into it. Then, mechanical equipment is used to push it to the location where it needs to be laid. At the same time, the surrounding soil is compacted to ensure stability. This method can effectively reduce ground excavation and traffic interference, and is particularly suitable for busy urban areas or historical building protection areas where the surface needs to be protected.

[0003] Reinforced concrete jacking pipes are used underground and are subjected to high pressure. If they are damaged by pressure or impact during use, it will affect the overall use of all the reinforced concrete jacking pipes connected to them.

[0004] Therefore, an impact-resistant F-shaped steel-supported reinforced concrete jacking pipe is needed to solve the above problems. Utility Model Content

When the steel ring 5 is connected to the previous set of connecting rings 8, it can provide anti-collision protection at the contact point. At the same time, multiple sets of reinforcing rods 9 are located inside the concrete pipe 1. After the upper and lower contact platforms 13 are locked on the inner wall of the concrete pipe 1, the fixing bolts 16 are tightened to fix the contact platforms 13. The multiple sets of reinforcing rods 9 are locked inside the concrete pipe 1, which can strengthen the concrete pipe 1 from the inside and increase the overall compressive and impact resistance of the concrete pipe 1.
