Example Embodiment

[0024] In the following, the concrete layered pouring type arch ring construction method provided by the present invention will be further described with reference to the drawings and specific embodiments.

[0025] See figure 1 , The present invention provides a concrete layered pouring type arch ring construction method, including the following steps:

[0026] The construction of the arch;

[0027] Install steel arches;

[0028] Install steel bars and embedded parts;

[0029] Installation template;

[0030] The arch ring concrete is poured in layers;

[0031] After maintenance, remove the formwork and steel arch.

[0032] Further, the concrete pouring of the arch ring adopts symmetrical segmented ring construction. The arch ring is divided into 5 sections in the longitudinal direction and 2 rings in the vertical direction. The first ring is poured first, and the ring is formed to achieve the design After the strength is strengthened, the second ring is poured, and the thickness of the f...

Abstract

The invention provides a concrete layered pouring type arch ring construction method, which belongs to the technical field of arch bridge construction devices. The method comprises the steps of carrying out arch support construction; mounting a steel arch frame; installing reinforcing steel bars and embedded parts; mounting a formwork; pouring arch ring concrete in a layered and segmented mode; and after maintenance, removing the formwork and the steel arch frame. The technical problem that in the concrete pouring process, the steel arch frame cannot bear loads, and consequently distortion anddeformation and even collapse happen is solved.

Description

technical field [0001] The invention belongs to the technical field of arch bridge construction devices, and more specifically relates to a concrete layered pouring type arch ring construction method. Background technique [0002] Arch bridges are the most common construction projects that cross rivers and mountains. The construction process of arch bridges needs to be rigorous and follow the design standards. Uneven stress causes the supporting steel arch to tilt, bend, twist or even collapse due to overload. Contents of the invention [0003] The object of the present invention is to provide a concrete layered pouring method for arch ring construction, aiming to solve the technical problem that the steel arch frame cannot bear the load during the concrete pouring process, and thus twists, deforms or even collapses. [0004] In order to achieve the above object, the technical solution adopted by the present invention is to provide a concrete layered pouring arch ring con...
