Abstract
The invention provides a recycled concrete gravity-type U-shaped abutment. The front wall and the side wall of the recycled concrete gravity-type U-shaped abutment are made of recycled rubble concrete. The invention also discloses the mixing ratio of recycled concrete for making the gravity-type U-shaped abutment and a manufacturing method of the recycled concrete gravity-type U-shaped abutment. The invention can effectively reduce costs, save natural stone resources, protect the ecological environment, and can also solve the problems of local waste stacking, land occupation and environmental pollution.
Description
technical field [0001] The invention relates to the technical field of bridge engineering and new environment-friendly building materials, in particular to a recycled concrete gravity U-shaped abutment and a manufacturing method thereof. Background technique [0002] With the continuous advancement of human civilization and the acceleration of urbanization worldwide, the per capita consumption of concrete materials is increasing, and at the same time, environmental problems are becoming more and more significant. Random mining and abuse of natural sand and gravel resources have caused landslides, riverbed diversions, and seriously damaged the natural environment. Due to the depletion of resources caused by long-term mining, the phenomenon of continuous flow of original sand and gravel aggregates no longer exists. [0003] On the other hand, concrete structures usually only have a life cycle of several decades. The waste concrete demolished every year in the world produces a...
