High-pressure water crushing technology: an efficient, safe and environmentally friendly concrete demolition method
Working principle:High-pressure water crushing works by pressurizing water to a high-pressure state, and then spraying high-pressure water flow through a special nozzle onto the surface or inside of the concrete. The speed and pressure of high-pressure water can create huge impact and cutting forces that can fracture and shatter concrete.
Applicable scene:High-pressure water crushing is suitable for the demolition of various concrete structures, including walls, floors, pavements, etc. Compared with other crushing methods, high-pressure water crushing does not produce noise and vibration, and has less impact on the surrounding environment and structures. Therefore, it is particularly suitable in places where quietness or the surrounding environment need to be protected.
Work steps:Concrete crushing with high-pressure water generally requires the following steps: First, assess and prepare the work area to determine the scope and objectives of crushing. Then, use high-pressure water equipment to pressurize the water to the appropriate pressure and spray the water through the nozzle onto the concrete surface or inside. During the crushing process, the speed and angle of the water flow need to be adjusted according to specific conditions to achieve the best crushing effect. Finally, debris and residue are removed, and waste disposal and cleanup work is carried out.
Large area concrete hydraulic demolition of road and bridge pavement
In the construction and maintenance process of road and bridge pavement layers, large-area concrete hydraulic demolition technology is widely used. This innovative method uses high-pressure water flow to remove concrete from road and bridge paving to achieve a more efficient, reliable and environmentally friendly result.
Principle:Large-area concrete hydraulic demolition technology uses high-pressure water flow through nozzles to shoot onto the concrete surface, generating huge impact and shear forces. This force effectively breaks down the structure of concrete, making it loose and easily removed. The high-pressure water flow can also quickly wash away the demolition debris, keeping the work area clean and providing good preparation conditions for subsequent construction.
Application:Concrete hydraulic demolition technology can be used to remove old pavement layers in road and bridge construction to prepare for new pavement. At the same time, it can also be used for the demolition and repair of old bridges, as well as for the repair and reconstruction of road surfaces. In addition, large-area concrete hydraulic demolition technology can also be used to demolish large-area concrete structures such as parking lots, airport runways, and road medians.
