Abstract

The invention discloses a fabricated formwork of an egg-shaped tunnel. The fabricated formwork of the egg-shaped tunnel comprises foot formworks, shoulder formworks and capping formworks, wherein thefoot formworks are pressed on a web plate of a reinforced concrete bottom plate, the web plate is an arc-shaped plate, the bottom surfaces of the foot formworks are inclined surfaces attached to the web plate, the shoulder formworks are pressed on the foot formworks, the shoulder formworks are arc-shaped plates, the capping formworks are arc-shaped plates, the two ends of the capping formworks areconnected to the two shoulder formworks, and the curvature of the capping formworks is larger than that of the shoulder formworks. According to the fabricated formwork, external supporting is not needed, the foot formworks serve as supports, the shoulder formworks and the capping formworks are sequentially arranged on the foot formworks, and therefore the whole fabricated formwork forms a self-stabilizing structure so as to resist loading force generated during pouring and vibrating; and in addition, the foot formworks are connected with the shoulder formworks through bolts, and the shoulderformworks are connected with the capping formworks through bolts, so that disassembly and assembly are convenient. The invention further discloses a lining method of the egg-shaped tunnel.

Description

technical field [0001] The invention relates to the field of tunnel lining, more specifically, to an assembled formwork for an egg-shaped tunnel and a lining method for an egg-shaped tunnel. Background technique [0002] Egg-shaped tunnels are the more common shape in tunnels. The speed of tunnel lining has a great influence on the progress and safety of the project. At present, steel formwork trolleys are mostly used for the lining formwork of egg-shaped tunnels, but a large number of external supports are required when steel formwork trolleys are used. Then it takes a lot of time to assemble the external support before lining, and it takes a lot of time to disassemble the external support after the lining is completed. In this way, the lining speed will be reduced, which will seriously affect the progress of the project and the safety of the project. [0003] Therefore, how to improve the lining speed of the egg-shaped tunnel, so as to ensure the progress of the project...
