Applications Of The Cement Demolition Project

　　At present, the demolition of concrete in China primarily relies on conventional methods such as manual jackhammers and mechanical crushing. These techniques suffer from significant drawbacks, including excessive dust generation, substantial vibration, and considerable damage to the existing structure. Consequently, government regulatory agencies and construction firms are actively seeking innovative, environmentally friendly, and energy‑efficient alternatives to replace traditional methods, with the aim of enhancing operational efficiency, reducing maintenance costs, and extending the service life of concrete structures.

　　Moreover, the ultra‑high‑pressure water‑jet method for demolishing concrete offers distinct advantages over conventional mechanical demolition techniques. Abroad, it is already widely employed in construction projects such as bridge and road rehabilitation and reinforcement, as well as building renovation and repair. For instance, beginning in the 1990s, advanced countries including those in Europe and North America, Japan, and South Korea have adopted this technology for bridge and road strengthening and retrofitting; Sweden’s bridge code explicitly stipulates that concrete surface treatment must be carried out using high‑pressure water‑jet technology prior to any repair work.

　　Advantages of the Ultra-High-Pressure Hydraulic Demolition Scheme

• The high-pressure water jet concrete removal process offers advantages such as dust-free operation, minimal vibration, and high efficiency, while causing no damage to the existing structure.
• It has essentially overcome the high-risk drawbacks of traditional manual processes.

The construction employs an ultra‑high‑pressure hydraulic process, which does not damage the existing concrete or reinforcing steel. Additionally, the retained concrete has been roughened to increase the contact area between the new and old concrete, thereby enhancing bond strength. This approach not only improves construction efficiency and reduces overall costs but also helps minimize the waste of societal resources.
