Embodiment Construction

[0032] The present invention will be further described below in conjunction with accompanying drawing.

[0033] like figure 1 As shown, the tunnel lining trolley 100 includes a formwork assembly 1 matching the tunnel profile. The template assembly 1 includes a left top template 11 , a right top template 12 , a left template 13 and a right template 14 . Wherein, the left top template 11 and the right top template 12 are arranged oppositely, a gap 15 is formed between the upper ends of the two, and the distance of the gap 15 in the transverse direction is adjustable. The left template 13 and the right template 14 are arranged oppositely, and the left template 13 and the right template 14 are connected with the lower ends of the left top template 11 and the right top template 12 respectively. The formwork assembly 1 also includes a top formwork 16 , which is detachably connected to the left top formwork 11 and the right top formwork 12 to adapt to the change of the gap 15 .

Abstract

The invention relates to a tunnel lining trolley which comprises a template assembly, wherein the template assembly is matched with the tunnel profile and comprises a left top template, a right top template, a left side template, a right side template and a top template; the left and right top templates are opposite to each other; a gap is formed between the upper ends of the left and right top templates; the gap is adjustable in the transverse direction; the left and right side templates are opposite to each other and respectively connected with the left and right top templates; the top template is adapted to the gap; two sides of the top template are detachably connected with the left and right top templates.

Description

technical field [0001] The invention relates to a tunnel lining trolley, in particular to a variable-span tunnel lining trolley for a single-track railway. Background technique [0002] At present, in the tunnel lining construction process, the tunnel is generally lined with a tunnel lining trolley. The general tunnel lining trolley includes the trolley formwork, the trolley and formwork entry and exit system and operating platform in the trolley formwork. [0003] During the construction of variable-span tunnels on single-track railways, since the tunnel sections have different widening values, the use of a single tunnel lining trolley in the prior art cannot meet the lining requirements of the widened section tunnel profile, increasing the construction difficulty. [0004] Therefore, it is necessary to develop a tunnel lining trolley that can be applied to single-track railway variable-span tunnels to reduce construction difficulty and improve construction quality. Con...
