Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a concrete pole cutting device. Background Art

[0002] In the official definition, concrete poles refer to the general term for engineering composite materials, in which aggregates are bonded into a whole by binders. The concrete used for the poles is a mixture of white sand, stone, cement and water in a certain proportion, also called concrete mixture. Before the cement slurry solidifies and hardens, the concrete has a certain workability, which is called fresh concrete. After hardening, the concrete is hardened concrete, commonly known as artificial stone. The presence of sand and gravel in concrete poles limits the shrinkage of cement stone, making the concrete have greater volume stability and better durability than using cement slurry alone, and has good technical and economic benefits. The various component materials in the concrete are strictly designed and mixed together in a certain proportion.
