Description

Technical Field

[0001] The utility model relates to the technical field of concrete roughening, and more specifically, to a concrete roughening device. Background Art

[0002] When pouring concrete in the reservoir dam of a water conservancy project, the layered pouring method will be used. The principle of the layered concrete pouring method is to divide the entire pouring process into multiple levels. Each layer must be fully vibrated and maintained to ensure the quality of the concrete, which can effectively avoid voids and defects in the concrete, improve its density and strength, and thus increase the stability and durability of the building. When pouring concrete in layers, the horizontal joint surface between the new and old concrete is the construction joint. In order to ensure the integrity of the building, before pouring the new concrete, the surface of the old concrete must be roughened to remove the cement film on the surface of the concrete, and make the surface fresh and clean, with half-exposed stones, so as to facilitate the close combination of the new and old concrete. At present, the roughening treatment of construction joints includes sandblasting, high-pressure water flushing, brushing, pneumatic pick or manual roughening. These roughening methods are mainly operated by manual roughening equipment, which has high labor intensity and low efficiency. Utility Model Content
