Recycled concrete structure for road and preparation method thereof

Abstract

The invention discloses a recycled concrete structure for a road and a preparation method thereof, and relates to the technical field of recycled concrete structures, the recycled concrete structure for the road comprises two side plates, a concrete prefabricated plate is arranged between the two side plates, and a first clamping groove is formed in the upper surface of the front end of the concrete prefabricated plate; a second clamping groove is formed in the lower surface of the rear end of the concrete prefabricated slab. Through mutual cooperation of a conical block, a hook, a fixing shaft, a movable plate, a U-shaped rod, an insertion plate, a first bolt and a second butt joint groove, a plurality of first bevel edge clamping blocks can be clamped into a plurality of first butt joint grooves, then a clamping device penetrates through a fixing through hole to be clamped into an insertion plate hole to fix a concrete prefabricated plate, and then the movable plate is rotated to fix the concrete prefabricated plate. The conical block is pulled to move into the butt joint hole, butt joint installation is completed, the problem that the construction period is long is solved through the prepared prefabricated plate, meanwhile, the structure is split, the purpose of transportation can be achieved through one transport vehicle, and the transport cost is reduced.

Description

technical field [0001] The invention relates to a recycled concrete structure, in particular to a recycled concrete structure for roads and a preparation method thereof. Background technique [0002] Recycled concrete refers to the waste concrete blocks after crushing, cleaning and grading, mixed with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel, mainly coarse aggregates, and then adding cement, water, etc. The research on recycled concrete in my country started late. Therefore, strengthening the development and utilization of waste concrete in my country can not only effectively solve the shortage of natural coarse aggregates, but also help protect the environment of the aggregate producing areas. It can reduce the stacking, land occupation and environmental pollution of urban waste, thereby ensuring the sustainable development of civil engineering in my country. [0003] At present, there are still some defect...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a road-use recycled concrete structure and its preparation method to solve the problem that the current utilization of recycled concrete proposed in the above-mentioned background technology is to first spread recycled coarse aggregate on the road surface, and then to solidify the coarse aggregate. Sprinkle cement mortar on the surface of the aggregate, and the construction period of such a road is often long, and it is necessary to use different transport vehicles to transport the coarse aggregate and cement separately, which increases the transportation cost.
