Dry-process stone-like kerb and preparation method thereof

Abstract

The invention discloses a dry-process stone-like curb which comprises the following components in percentage by weight: 10-30% of cement, 70-90% of tailing sand and 0.1-0.2% of an adhesive, and a preparation method comprises the following steps: S1, preparing raw materials and water in percentage by weight; s2, adding the raw materials into a high-speed stirrer, adding water for stirring, and obtaining dry hard concrete; s3, conveying the materials into a forming machine bottom material car hopper through a belt; s4, mechanical pressing molding; s5, demolding: automatically demolding by a machine after molding; s6, after demolding, transporting the kerb semi-finished product into a full-automatic curing kiln for curing; s7, transferring the qualified semi-finished kerb to a stacking area, and stacking the qualified semi-finished kerb; s8, maintaining a semi-finished product; s9, carrying out secondary treatment on the surface of the semi-finished product through water milling equipment to integrally achieve a natural stone effect; and S10, conveying the product to a finished product area for secondary inspection, and warehousing the qualified products. The invention relates to the technical field of kerbs. According to the invention, the problems of peeling, chipping and poor quality of the traditional curb are solved.

Description

technical field [0001] The invention relates to the technical field of curbstones, in particular to a dry-process imitation stone curbstone and a preparation method thereof. Background technique [0002] Curb stone is the abbreviation of the edge stones on both sides of the road surface, usually a strip structure between the road surface and the road shoulder on both sides of the road. Curb stones are usually laid on both sides of the road surface to separate the road surface from other structures. For example, a curb stone higher than the road surface can be provided between the sidewalk and the motorway. [0003] Curb stones are divided into cement concrete curb stones and natural stone curb stones according to their materials. At present, due to the impact of environmental protection, the application of natural stone curb stones is hindered. Due to its low strength and poor frost resistance, traditional cement concrete curbs are easily peeled and broken by sunlight and c...

Problems solved by technology

[0003] Curb stones are divided into cement concrete curb stones and natural stone curb stones according to their materials. At present, due to the impact of environmental protection, the application of natural stone curb stones is hindered

Due to the low strength and poor frost resistance of traditional cement concrete curbs, it is easy to peel off and fall off due to the influence of sunlight and climate, which affects the engineering quality of the entire road surface, and is increasingly not recognized by the market
