[0001] The invention belongs to the technical field of concrete processing and relates to a concrete locking block, in particular to an environmentally friendly concrete locking block and a preparation method thereof. Background Art

[0002] With the development and application of the concrete industry, concrete is used in various forms in different fields. In water conservancy projects, such as river bank protection and embankments, it is necessary to prevent water from scouring the slope and soil loss. Traditional slope protection methods are often ineffective when facing high water flow speeds and wave scouring. Concrete lock blocks are laid in an interlocking manner to enhance the stability of the slope, and reduce soil loss by planting grass, etc. At the same time, pollution is reduced by recycling and reusing construction solid waste.

[0003] The existing concrete lock block processing has a low degree of automation and high labor costs, and the quality is unstable due to manual processing.

[0004] Therefore, we propose an environmentally friendly concrete locking block and a preparation method thereof. The environmentally friendly concrete locking block is easy to assemble, easy to install, has a fast drainage speed and a strong protective ability. The preparation method has a high degree of automation, good molding effect and stable quality. The environmentally friendly concrete molding equipment used in the preparation method of the present invention can perform stable and automated production of concrete locking blocks through automatic input, limited intermittent vibration, quantitative material distribution, stable adsorption and transportation, pressing and molding, and stable output.

[0007] The working principle of the present invention is: when the concrete lock blocks are used for slope protection to prevent soil erosion, the concrete lock blocks are assembled, the T-shaped blocks are embedded in the T-shaped grooves of the adjacent concrete lock blocks, the overlapping blocks are pressed on the overlapping grooves, and the arc-shaped water passages of the front and rear adjacent concrete lock blocks are connected; After the concrete lock block is installed, slope protection plants are planted in the rectangular grass planting holes to protect water and soil. When it rains, the wedge-shaped water collection channel collects water and transports it to the arc-shaped water channel. Rainwater passes quickly through the arc-shaped water channel and is discharged, reducing soil expansion caused by rainwater infiltration, thereby inhibiting slope deformation and enhancing protection capabilities.

[0008] A method for preparing an environmentally friendly concrete lock block, the preparation method steps are as follows: Step 1: Construction waste enters the site; after being collected, the construction waste is transported into the factory and stored and sorted in the factory yard; Step 2: Multi-stage crushing and impurity removal: qualified raw materials are crushed in multiple stages, and the slag, light impurities and metals in the construction waste are removed at each stage of crushing; Step 3: batching and mixing; the obtained recycled aggregate, fly ash, cement and water are mixed according to weight proportions, and the weight proportions of each component are: 310 parts of cement, 165 parts of water, 589 parts of sand, 80 parts of fly ash and 1044 parts of recycled aggregate, and are sequentially fed into a mixer for mixing and stirring to obtain environmentally friendly concrete; Step 4: molding; placing the obtained environmentally friendly concrete into a molding device, vibrating and pressing it into a semi-finished locking block in a molding mold, and conveying the locking block mold and the semi-finished locking block therein out; Step 5: Steam curing: sending the mold and the semi-finished locking block therein into a curing kiln for steam curing.
