Abstract

The invention provides an irregularly widened arched section tunnel construction device and a construction method. The construction device comprises a supporting system and a panel system which is arranged on a vertical side surface of the supporting system and is in a smooth arc shape, wherein a longitudinal plane of the supporting system is provided with a vertical I-shaped wooden beam supporting seat, and a lower end of the supporting system is provided with a universal wheel. The construction method adopts a small unit combination method and comprises the following steps: a left side walland a right side wall are respectively formed into a system; the tunnel is divided into a plurality of side wall construction intervals according to a widened section, a plane curve condition and thechannel length; side wall reinforcing steel bars of irregular sections in different construction intervals are bound; an independent support frame is assembled; transverse and longitudinal panel systems are assembled; the supporting system is formed according to the length of an irregularly widened section of each construction interval; concrete pouring and curing are carried out on the side wallof the construction interval; and the supporting system and the panel system are moved to a next construction interval through the universal wheel. The irregularly widened arched section tunnel construction device is convenient to move and is suitable for side wall construction in the irregularly widened arched section tunnel.

Description

technical field [0001] The invention relates to the field of tunnel door lining formwork construction, in particular to a construction device and a construction method of a side wall formwork. Background technique [0002] In the tunnel construction, the irregularly widened arched section tunnel is asymmetrical, uneven and irregularly widened on both sides of the construction tunnel, which makes the construction difficult, and the ordinary side wall construction device is not suitable for the construction site. . [0003] At present, the side wall trolley commonly used in tunnel construction is only suitable for the standard section structure, and cannot adapt to the widened section of the structure; Adapt to Free Transform. The widening section uses a cantilever formwork trolley, and the cantilever section of the trolley is prone to deformation and requires high rigidity. At the same time, the use of trolleys is costly, takes up a lot of land and has a long construction ...
