Demolition Project-Wall Cutting

Selective demolition and structural modification of reinforced concrete walls at a commercial and infrastructure site.

The project involved precision cutting of reinforced concrete walls as part of a structural modification and controlled demolition work in a commercial and infrastructure site. Due to site constraints and the need for minimal disturbance, a high-frequency electric wall saw system was selected for its precision, versatility, and safety.

Machine Used: High Frequency Wall Saw (Remote-Controlled)

Application Scope

• Cutting reinforced concrete walls up to 730 mm thick

• Creating precise openings for doorways, windows, and ducts

• Sectional dismantling of retaining walls and structural slabs

• Concrete separation for retrofitting and redesign
  

Work Description: The high-frequency wall saw was mounted on a modular aluminum track fixed vertically to the concrete surface. The cutting process was operated remotely, allowing the operator to control feed rate, blade rotation, and cutting depth from a safe distance, thereby improving operator safety and visibility in dusty and constrained environments.

The saw blade, water-cooled to suppress dust and prolong tool life, delivered clean and vibration-free cuts through heavily reinforced concrete. The machine’s powerful high-frequency motor ensured consistent performance even during deep cuts and prolonged usage.

Key Features & Advantages:

• Remote-controlled operation: Enhances safety, especially when working at heights or in confined spaces

• High cutting capacity: Suitable for concrete up to 730 mm thick

• Minimal vibration and noise: Ideal for sensitive environments like hospitals, offices, and urban infrastructure

• Precise and straight cuts: Facilitates easier dismantling and reinstallation

• Efficient water cooling: Keeps blade temperature low, reduces dust, and extends blade life

Challenges & Solutions:

• Tight working space: The compact saw head and rail system enabled installation and operation in confined conditions

• Noise sensitivity: The low-noise electric drive made it suitable for daytime works in populated areas

• Rebar-dense concrete: The high torque and optimized blade ensured smooth cutting through heavy reinforcement

Conclusion

The High Frequency Wall Saw proved to be a reliable and efficient solution for structural cutting tasks, offering clean, precise, and safe operations. Its advanced remote-control system and powerful motor significantly reduced labor intensity and increased overall productivity.
