The longitudinal supporting rod E serves as a force beam to bear the weight of the plurality of ring steel bars. Since the sleeve at the joint of the two ring steel bars has a step, the longitudinal supporting rod E is preferably a cylinder in this embodiment, which can conveniently pass through the step; however, the longitudinal supporting rod E will rub against the steel bar when passing through the step, and the longitudinal supporting rod E can also be in other shapes (such as a cuboid), and a supporting block F (i.e. a cylindrical supporting block) is arranged on the longitudinal supporting rod E, which can conveniently pass through the step and also prevent the ring steel bar from directly contacting the longitudinal supporting rod E to cause friction and wear the longitudinal supporting rod E, and the cylindrical supporting block F can be in multiple segments or a whole.

In addition, a protective fence is arranged on the top operation platform and the side operation platform to improve construction safety. A staircase 9 is also arranged on the side or inside of the main body framework for personnel to pass through.

[0043] The technical solution of the embodiment is applied, specifically:

[0044] The hoop reinforcement is advanced to the required length and laid flat on the ground to the right of the device (the right side is the right side facing the main skeleton 1), at this time the hoop reinforcement is straight.

[0045] The main skeleton 1 travels to the corresponding station and adjusts the position through the jacking and transverse mechanism 1.3 to complete the centering.

[0046] The rotary power element 2.2 in the installation mechanism 2 acts to drive the entire installation arm 2.1 to rotate and adjust the position of the entire installation mechanism 2 to the right side of the short side wall reinforcement placement through the action of the telescopic power element 2.3.

[0047] The worker fixes one end of the reinforcement 10 to the reinforcement hanger C in the first reinforcement clamping element 2.4, and can complete the binding and fixing work of single or multiple reinforcements according to the needs.

[0048] The rotation power element 2.2 in the mounting mechanism 2 is actuated to make the whole mounting arm 2.1 drag the reinforcing steel bars 10 to rotate to the left side (the left side is the left side facing the main skeleton 1) of the low side wall (in this process, the telescopic power element 2.3 can adjust the overall length of the mounting arm according to the requirement), in this process, the ring-shaped reinforcing steel bars are in a semicircular shape and are placed on the reinforcing steel bar positioning mechanism 3 in the contracted state under the action of gravity, and the position of the ring-shaped reinforcing steel bars is below the inner ring reinforcing steel bar mounting contour surface 8 (the reinforcing steel bar positioning mechanism 3 is in the contracted state, so that the mounting mechanism 2 has the space for rotation). When the mounting mechanism 2 reaches the left side of the low side wall, the fixing between the reinforcing steel bar hanger C and the end of the reinforcing steel bar 10 is cancelled, and the left side of the side wall reinforcing steel bar is fixed with the ring-shaped reinforcing steel bar by means of the side wall reinforcing steel bar butt joint slide rail 4. At this time, the distance between the left side reinforcing steel bar hanger C is consistent with the distance between the ring-shaped reinforcing steel bars, but the reinforcing steel bars far from the left side are easy to be mixed together. At this time, the reinforcing steel bar combing roller D in the first reinforcing steel bar clamping element 2.4 is adjusted to extend, the ring-shaped reinforcing steel bars fall into the gap of the reinforcing steel bar combing roller D under the pulling of the reinforcing steel bar hanger C, the actuation of the rotation power element 2.2 makes the mounting arm 2.1 return to the left side of the low side wall, in this process, the reinforcing steel bar combing roller D forms a comb tooth shape and gradually separates the reinforcing steel bars that may be mixed together. Then the reinforcing steel bars are pushed to the outer ring reinforcing steel bar mounting contour surface 7 by the reinforcing steel bar positioning mechanism 3, at this time, the ring-shaped reinforcing steel bars are in a semicircular shape and are placed on the reinforcing steel bar positioning mechanism 3 in the pushed-out state under the action of gravity, since the length of the ring-shaped reinforcing steel bars is a designed fixed value, when the reinforcing steel bar positioning mechanism pushes the ring-shaped reinforcing steel bars to the outer ring reinforcing steel bar mounting contour surface 7, the right end (the right end corresponds to the right side) of the ring-shaped reinforcing steel bars is just located at the right side of the side wall reinforcing steel bar, at this time, the right side of the side wall reinforcing steel bar is fixed with the ring-shaped reinforcing steel bar. Then the longitudinal reinforcing steel bars are manually assisted to be bound on the ring-shaped reinforcing steel bars (each longitudinal reinforcing steel bar connects several ring-shaped reinforcing steel bars in the tunnel direction), after all the longitudinal reinforcing steel bars are bound, the outer layer reinforcing steel binding is completed. Finally, the inner layer reinforcing steel binding is bound, the inner layer reinforcing steel binding is to push the reinforcing steel bars to the inner ring reinforcing steel bar mounting contour surface 8 by the reinforcing steel bar positioning mechanism 3, and the remaining steps are consistent with the outer layer reinforcing steel binding, and the above steps are repeated to complete the inner layer reinforcing steel binding.

For the skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the utility model should be included in the protection scope of the utility model.
