Research on Reinforcement Cage Overall Binding and Concrete One-time Forming Technology for Box Culvert
Madagascar 5A national highway project has the construction characteristics of a large number of box culverts and long distance.In this regard,this paper introduces the control points of the box culvert reinforcement cage factory tire frame overall binding forming,the box culvert formwork one-time installation,and the box culvert concrete one-time pouring forming.The project uses steel pipes with a diameter of 48 mm to set up reinforcing cage binding tire frames.The size of the tire frame can be adjusted at any time according to the specifications of the reinforcing cage,which is simple and economical.At the same time,the factory processing of the box culvert reinforcement cage replaces the traditional on-site secondary binding reinforcement construction.The one-time installation process of box culvert formwork is innovated to enable concrete to be poured and formed in one go,eliminating horizontal construction joints,improving efficiency,and ensuring quality,which provides reference for similar box culvert construction.
