Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a tunnel secondary lining steel cage processing system. Background Art

[0002] During the tunnel construction process, steel cage binding is a necessary process. Only after the steel cage is tied can the second lining concrete of the tunnel be poured. The quality and efficiency of the steel cage binding directly affect the quality and progress of subsequent processes and even the entire tunnel construction. The steel cage is mainly composed of circumferential steel bars, longitudinal steel bars and stirrups. The steel cage binding requires that the circumferential steel bars are arranged in an arc shape along the arch direction of the tunnel, with a spacing of generally 200mm, and are divided into two layers, inner and outer. The radius of the inner layer of circumferential steel bars is generally 6720mm, and the radius of the outer layer of circumferential steel bars is determined according to the surrounding rock. The spacing between the inner and outer layers of circumferential steel bars is between 260-360mm. The longitudinal steel bars (generally 14mm in diameter) are arranged along the circumference of the inner wall of the tunnel, with a spacing of generally 250mm. The longitudinal steel bars are respectively tied with the inner and outer layers of circumferential steel bars. The stirrups (generally 8mm in diameter) are connected at the intersection of the inner and outer layers of circumferential steel bars and the longitudinal steel bars, and their two ends are respectively connected to the inner and outer layers of circumferential steel bars.

[0003] In traditional tunnel construction, the loading of steel bars is mainly done manually. However, as the main reinforcement of the tunnel reinforcement cage, the circumference of the circumferential steel bars is usually 20 to 38 meters after two or three of them are connected to form a whole on the ground (the diameter of the circumferential steel bars is generally about 18-25mm, the length is 27 meters, and the weight is about 100kg). Such length and weight make the operation of circumferential steel bars in the tunnel extremely difficult. During the construction process, it takes about 10-12 people to pull it. The workers need to pull it to the designated position first, and then stand at different positions on the steel bar trolley to pass it on the trolley together, and then lift it up together to position and fix it. A 6-meter-long tunnel work unit has a total of 60 circumferential steel bars in the inner and outer layers, which needs to be reciprocated 60 times. Its work efficiency is low and many people are involved. Summary of the invention
