How to Demolish Concrete Walls

Concrete Wall Demolition Methods:

Process Flow: Positioning, Laying Out → Drilling Process Holes (Lifting Holes) → Pre-Lifting → Cutting → Concrete Blocks Lifting and Removal.

Each cutting block must be temporarily hoisted and secured through the lifting hole to prevent sudden collapse. Safety protection facilities and warning signs must be installed in the areas where cutting is completed to prevent falls of people or objects. The entire demolition area should follow the construction sequence from top to bottom and from left to right.

1. Block Positioning and Line Setting: Utilize measuring instruments to position the areas to be cut into blocks. Use a chalk line to mark the positions, ensuring the accuracy of the block cutting locations.

2. Drilled process holes (hoisting holes).

3. Pre-hoisting

4. Cutting: Block cutting is performed using a water drill with a diameter of 63mm.

5. Concrete block lifting and removal: Straightly cut and separate the original wall from the demolition section. Repair or remove areas where the openings do not meet the requirements. Remove the debris from the demolition section promptly. Due to the significant weight of the concrete wall, for ease of removal, the dimensions of the cut concrete blocks cannot be too large. The dimensions of a single concrete wall block are determined to be 750mm x 550mm x 350mm, weighing 361kg.
