Description

Technical Field

[0001] This utility model relates to a trolley for cable trenches in small-section tunnel drainage ditches, and more particularly to a trolley device for synchronous construction on both sides of cable trenches in small-section tunnel drainage ditches. Background Technology

[0002] Currently, in the construction of small-section tunnels, existing construction trolleys for drainage ditches and cable trenches are designed with a mold box on one side. Typically, the construction of the drainage ditches and cable trenches on one side is completed before the construction of the other side is carried out. Since the construction of both sides is carried out separately, the progress is slow, the time occupied by the trolley in the tunnel is long, the construction progress is slow, the operating range of the equipment is affected, and the construction progress of the tunnel section is reduced. In view of the above reasons, a trolley device for simultaneous construction of drainage ditches and cable trenches on both sides in small-section tunnels is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the limitations of existing construction trolleys for cable trenches, which typically require the completion of concrete construction on one side of the cable trench before proceeding to the other, resulting in slow construction progress and impacting the overall construction schedule. This invention provides a trolley device for simultaneous construction on both sides of a small-section cable trench in a tunnel. This trolley features two pairs of booms on each side, with the booms and winch sliders controlling the formwork box and adjusting the construction width on both sides. The winch controls the synchronous lifting and lowering of the formwork box on both sides for construction and demolding. This allows a single construction section to be completed in one go, minimizing the space and time required for tunnel construction, accelerating the progress of the cable trench project, saving construction time and costs, and ensuring construction quality.

The pair of cable trough template boxes are respectively set as power cable boxes and communication cable boxes. Longitudinal side plate support strips are evenly distributed on the inner side of the side box panels of the water ditch template box and the pair of cable trough template boxes.

[0006] A pair of internal support plates for the water ditch are installed in the water ditch template box. The two sides of the pair of internal support plates are evenly distributed with reserved support slots, and the side plate support strips are respectively installed in the support slots. A box opening positioning plate is welded to the upper end of the water ditch template box. A pair of box beam connecting plates are respectively set at the upper end of the pair of internal support plates. A box opening positioning plate is set at the lower part of one side of the pair of box beam connecting plates.

[0008] A pair of box beams are installed at the top of both ends of the water ditch template box and the pair of cable ditch template boxes on one side of the construction trolley. Lifting lugs are installed at the center of the upper end of the pair of box beams, and hooks are installed between the lifting lugs and the wire rope. Box beam connecting plates for the water ditch template box and the pair of cable ditch template boxes are installed on one side of the lower end of the pair of box beams.
