Description

Technical Field

[0001] The present invention relates to the technical field of bridge waste recycling, and particularly relates to a waste recycling device after bridge demolition. Background Art

[0002] When a bridge reaches the end of its service life or cannot continue to meet the safety use requirements due to reasons such as design load, material aging, and structural damage, demolition treatment must be carried out. A large number of concrete blocks generated during the demolition process are not only huge in volume, but also contain steel aggregates, cracks, and pollutants. If directly landfilled or discarded, they will not only occupy land resources, but also may cause secondary pollution to the groundwater and soil environment. Therefore, recycling these concrete blocks can achieve resource recycling, reduce carbon emissions, and provide strong support for the sustainable development of the city.

[0003] However, the existing recycling operations usually directly load and transport the concrete blocks in the old bridge structure by a large forklift. However, due to the overly large volume of the concrete blocks, it is difficult for blocks of different shapes to fit tightly together during the loading process, resulting in the underutilization of the space in the silo or transport vehicle, thus seriously reducing the recycling efficiency. At the same time, the concrete blocks often contain uncut steel bars. If the concrete and steel bars are not separated at the source, it will lead to a reduction in the economy of the entire recycling system. To solve the above problems, we propose a waste recycling device after bridge demolition. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a waste recycling device after bridge demolition to solve the problems raised in the background art.
