With the development of high-speed and heavy-duty road transportation, due to the repeated action of heavy vehicles, a large number of simply supported slab beam bridge spans are suffering from increasingly serious structural diseases and bridge deck damage problems. Therefore, it is necessary to regularly renovate the existing old bridge. High pressure water concrete crushing equipment plays an important role in urban bridge renovation.
The high-pressure water concrete crushing equipment adopts high-pressure water jet technology, which physically crushes pure high-pressure water and can crush and erode concrete without damaging the steel bars and steel mesh inside the concrete. Concrete has a microporous structure, and high-pressure water jets can pass through the surface of the concrete, creating an overpressure inside the concrete. When this pressure exceeds the tensile strength of the concrete, it causes it to break.
The high-pressure water concrete crushing equipment adopts ultra-high pressure water flow, which can achieve horizontal, vertical, top, and narrow space crushing. By using PLC programming control, the nozzle working target distance, linear running speed, nozzle speed, and independently adjustable equipment speed and crushing speed can be set, making the working surface more precise. By controlling the robot through a remote control, it can move within a specified range with high crushing accuracy, good quality, and good safety. The corresponding pressure and flow rate can be adjusted, and the nozzle of the corresponding model can be selected to complete various construction crushing from surface roughening to crushing with an accuracy controlled within 3mm.
