Project Overview
This case study documents the exceptional performance of our SDS-Max tool series in a large-scale high-rise building demolition project. Located in the city center, the project involved demolishing a 20-story commercial building with a total floor area of 15,000 square meters.
Project Basic Information
- Project Location: Downtown commercial district
- Building Type: 20-story commercial building
- Floor Area: 15,000 square meters
- Project Timeline: Originally planned 6 months, actually completed in 4.2 months
- Main Materials: Reinforced concrete structure
Challenges Faced
Technical Challenges
- High-Strength Concrete: Building used C40 grade high-strength concrete, traditional tools were inefficient
- Dense Reinforcement: High rebar density with diameters up to 32mm increased demolition difficulty
- Precision Demolition: Need to protect adjacent buildings, requiring precise demolition range control
- Noise Control: Downtown location required strict noise level control
Time Pressure
- Owner required early completion to align with new construction project timeline
- Limited weather window periods
- Government permit time restrictions
Solution
Tool Selection Strategy
After detailed evaluation, we recommended the following SDS-Max tool combination:
- SDS-Max Demolition Hammer: For main structure demolition
- Professional Chisel Set: Including flat chisels, pointed chisels, groove chisels
- Drilling Tools: For pre-drilling and controlled demolition
- Cutting Tools: Precise cutting of rebar and concrete
Technical Advantages
- High impact energy: 17 joules impact energy, easily breaks high-strength concrete
- Precise control: Adjustable impact force, adapts to different demolition needs
- Low vibration design: Reduces impact on surrounding structures
- High durability: Carbide tips with long service life
Implementation Process
Phase 1: Preparation (1 week)
- Site survey and tool configuration
- Operator training
- Safety measure deployment
- Adjacent building protection measures
Phase 2: Main Demolition (12 weeks)
- Top-down demolition: Starting from top floor, demolishing floor by floor
- Zoned operations: Dividing each floor into 4 work zones
- Precise control: Using SDS-Max tools for precise demolition of designated areas
- Real-time monitoring: Monitoring vibration and noise levels
Phase 3: Cleanup and Finishing (4 weeks)
- Foundation structure demolition
- Waste cleanup and sorting
- Site restoration
- Quality acceptance
