Hand-held powerful chisel The traditional mechanical chisel's chiseling method is to use a sharp striking tool to hit the concrete surface with a piston to make the old and new concrete bond firmly. However, the traditional chiseling method has various disadvantages, such as low efficiency, mechanical oscillation force causes the transmission of sound waves, damages the main body to be chiseled, and affects the service life of the main body. At present, for small area chiseling (partial chiseling, facade chiseling, side chiseling, top chiseling), you can use a hand-held small chiseling machine, which has good effect and will not cause damage to the original structure. damage.

1. Since many current chiseling machinery products will not only destroy the protective layer of reinforced concrete, but also cause damage or even catastrophic damage to the original structure, so now in many projects, especially the concrete of bridges and tunnels In chipping, many large mechanical chipping machines have been banned.

2. The most used and safest is the "lossless chiseling" of the high-pressure water jet. The construction method of bridge deck chiseling requires that the concrete bridge deck pavement reaches the designed concrete strength, and the surface is smooth, clean, free of pollution, impurities, oil stains, dust, etc.

3. First use a chiseling machine to chisel the surface of the bridge deck concrete surface, remove the floating slurry and debris on the surface, and then use a rotating wire brush sweeper to clean it, and then use a blower or vacuum cleaner to remove floating and fine particles. Rinse it again with a high-pressure water gun, and start construction after drying.
