AI Technical Summary
Technical Problem
The existing construction of tunnel invert arch and filling layer concrete pouring presents problems such as worker health threats, low efficiency and high cost. In addition, the existing trestle equipment has a complex structure and occupies a large amount of tunnel space.
Method used
By employing a horizontally movable mounting frame and concrete conveying mechanism, combined with a transverse track and a longitudinally moving full-arc trolley, continuous pouring of both sides can be achieved. Only one set of equipment is required, reducing space occupation and maintaining construction continuity.
Benefits of technology
It enables low-cost and efficient tunnel concrete pouring, reduces equipment space requirements, and improves construction continuity and traffic capacity.

Abstract
The trestle equipment comprises a main bridge, an installation frame and a transverse moving track, the transverse moving track is located above the main bridge, a passing channel for vehicles on the main bridge to pass through is formed between the transverse moving track and the main bridge, a transverse moving trolley is movably arranged on the transverse moving track, and the transverse moving trolley is connected with the installation frame. The transverse moving trolley is detachably connected with the mounting frame and used for moving the mounting frame to the side edge of the main bridge, a concrete conveying mechanism is arranged on the mounting frame, and the two sides of the main bridge are provided with a material distributing component used for being in butt joint with the concrete conveying mechanism and a supporting frame used for supporting the mounting frame. The supporting frame is provided with supporting rollers used for allowing the mounting frame to move in the longitudinal direction. The utility model has the advantages of simple structure, low cost, less occupied tunnel space and high construction continuity.
