Embodiment 2

[0058] This embodiment discloses a method for pouring concrete in a steel pipe using the concrete pouring device in a steel pipe for an arch bridge disclosed in Embodiment 1, including the following steps:

[0059] S1: Concrete is transported after the concrete pouring device in the steel pipe is built;

[0060] S2: Stop pumping after the concrete in the steel pipe overflows, and close the flow-stopping structure;

[0061] S3: cleaning the remaining concrete on the steel pipe;

[0062]S4: After the final setting of the concrete, remove the flow-stop structure, cut off the feed pipe, repair the cut of the feed pipe and the overflow hole.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a method for pouring concrete in a steel pipe of an arch bridge, a device and an application thereof. Background technique [0002] Concrete-filled steel tube arch bridges are filled with concrete in the steel tubes, and the expansion of the compressed concrete is limited due to the radial constraints of the steel tubes, so that the concrete is in a three-dimensional compression state, thereby significantly improving the compressive strength of the concrete. At the same time, the steel pipe has the functions of longitudinal main reinforcement and horizontal hoop, and can be used as a construction formwork to facilitate concrete pouring. During the construction process, the steel pipe can be used as a rigid load-bearing skeleton. The welding work is simple and the hoisting weight is light, which can simplify the construction process. Shorten the construction period. [0003] How...
