Large-aperture assembly-type reinforced concrete culvert member

Abstract

The invention provides a large-aperture assembly-type reinforced concrete culvert member. The culvert member is provided with a left side wall, a right side wall and an arch-shaped top plate, and two ends of the top plate are connected with upper ends of left and right side walls respectively to form a culvert unit. The top plate, the left side wall and the right side wall form a reinforced concrete member, and a plurality of reinforced concrete members are installed sequentially, so that the large reinforced concrete culvert is assembled by modular reinforced concrete members, the production process and the production quality can be controlled easily, effects of weather factors on culvert engineering construction are reduced, and the engineering cost is reduced; member line production is performed, the construction technology is simple, and the inherent quality and the appearance quality of the installed solid structure are improved greatly; and a factorization prefabrication mode of members is performed, so that waste of raw materials of concrete is reduced, pollution caused by covering of membrane curing is reduced, and the molded solid structure is smooth in line type, attractive in appearance and provided with good visual effects.

Description

technical field [0001] The invention relates to a component of a reinforced concrete culvert, in particular to a large-diameter assembled reinforced concrete culvert component. Background technique [0002] In recent years, the acceleration of infrastructure construction has ushered in the rapid development of expressways and urban road projects. The number of culverts crossing expressways and urban traffic projects has increased, which has led to challenges for traditional culvert engineering construction methods; Most of the culvert engineering construction methods in China are on-site vertical formwork pouring, which has many disadvantages, such as scattered construction points, difficult control of construction quality, long cycle of turnover of formwork and support materials, construction progress is greatly affected by winter and rainy seasons, and long construction period. Contents of the invention [0003] The technical problem to be solved by the present invention...
