Problems solved by technology

Among them, the curved formwork unit includes two side formworks and a top formwork. The process of outward expansion of the outer contour of the formwork unit will make the structural strength of the connection between the side formwork and the top formwork relatively weak. The existing tunnel lining trolley This part is often neglected, and it is easy to cause the concrete structure applied on the inner wall of the tunnel corresponding to this part to loosen, and the strength is not enough, causing a safety hazard in the tunnel

Embodiment Construction

[0018] Attached below figure 1 The present invention is described in further detail.

[0019] as attached figure 1 As shown, the present invention is a tunnel lining trolley, which includes an arc-shaped formwork unit 1, a skeleton unit 5, and an adjustment support unit 6; the formwork unit 1 includes first side formworks arranged in sequence along the arc direction Group 2, top formwork 3 and second side formwork group 4; the adjustment support unit 6 is arranged between the skeleton unit 5 and the formwork unit 1, which is configured to be able to actuate the first side formwork group according to the size of the tunnel section 2. The top formwork 3 and the second side formwork group 4 move outwards so that they fit the lining of the tunnel; the inner surface of the formwork unit 1 between the first side formwork group 2 and the top formwork 3 is provided with a The first gap 701 of the skid, one side of the skeleton unit 5 is connected with a first support member 801 for ...

Abstract

The invention discloses a tunnel lining trolley. The tunnel lining trolley comprises a cambered template unit (1), a skeleton unit (5) and adjusting supporting units (6). The template unit (1) comprises a first side template set (2), a top template (3) and a second side template set (4); a first gap (701) is arranged on the inner surface of the template unit (1) between the first side template set (2) and the top template (3), a first supporting part (801) is connected to one side of the skeleton unit (5), a second gap (702) is arranged on the inner surface of the template unit (1) between the second side template set (4) and the top template (3), and a second supporting part (802) is connected to the other side of the skeleton unit (5). The tunnel lining trolley has the advantages that the structural strength of the joints of the side templates and the top template can be guaranteed, so that the concrete structure applied to the tunnel inner wall corresponding to the positions is guaranteed to be higher, and the potential safety hazard of a tunnel is reduced.

Description

technical field [0001] The invention relates to tunnel construction equipment, in particular to a tunnel lining trolley. Background technique [0002] The tunnel lining trolley belongs to the special equipment that must be used in the secondary lining of the tunnel construction process, and is used for the lining construction of the inner wall of the tunnel. [0003] At present, the existing tunnel lining trolley mainly includes a skeleton unit, an arc-shaped formwork unit composed of a top formwork, two side forms and two bottom formworks, and a liftable support unit connecting the formwork unit and the skeleton unit. The support unit can push each side formwork to swing outwards with the corresponding bottom formwork, so that the outer contour of the formwork unit expands outwards, so as to fit tunnels of different sizes and sections. Among them, the curved formwork unit includes two side formworks and a top formwork. The process of outward expansion of the outer contour ...
