In building decoration, wall renovation and infrastructure reinforcement projects, wall roughening is a key process to ensure the bonding strength of subsequent finishes. Traditional mechanical roughening is easy to produce dust pollution and damage the basic structure. High-pressure water wall concrete roughening equipment relies on high-pressure water jet technology and has become the preferred equipment for wall pretreatment in modern projects.
The equipment uses a 500-2800 kg high-pressure pump as the power source, and sprays high-pressure water directionally to the concrete wall through a special fan-shaped nozzle, forming a uniform and rough "jagged" or "point-like" rough surface on the wall surface, which not only avoids cracking of the concrete surface caused by mechanical impact, but also adjusts the roughening depth through the water flow to adapt to the needs of different scenarios.
Its application scenarios cover many types of projects. In the decoration of new residential buildings, it can quickly roughen the surfaces of concrete shear walls and beams and columns. Compared with manual roughening, the efficiency is increased by 5-8. times, and has no dust pollution, complying with indoor environmental protection construction requirements; in old wall renovation projects, it can accurately remove old coatings and floating dust on the wall, and complete the roughening process simultaneously; in infrastructure projects such as bridges and tunnels, for arc-shaped and high-altitude walls, the equipment can be equipped with retractable high-pressure pipelines and multi-angle nozzles to easily complete roughening operations in areas that are difficult to reach with traditional equipment, ensuring the bonding stability of subsequent anti-corrosion and waterproof coatings.
In addition, the high-pressure water wall concrete roughening equipment only requires 1-2 people to operate, and the water consumption is low. The waste water can be recycled and processed through the water connection device, taking into account both efficiency and environmental protection. It is widely used in the field of base pretreatment of concrete structures such as building exterior walls, indoor floors, bridge decks, tunnel linings, and floor slabs. It is suitable for base roughening of new projects and surface treatment operations during renovation of old buildings.
