Pipe roof construction refers to that before tunnel excavation, along tunnel excavation contour line outside certain distance, steel pipe is punched into stratum and grouting is carried out, thereby forming a continuous shed structure, which plays important roles such as stratum reinforcement, surrounding rock pressure bearing and water stopping. However, the traditional pipe roof construction equipment and method face many challenges in practical application, highlighting the necessity of modifying excavator and realizing multi -directional rotation function.
