Diaphragm Wall Manufacturing: 9 Step Process
Step 1:
Building Guide Walls
Next, we build temporary walls on both sides of where we’re digging. These guide walls help keep everything straight and give support during construction.
Step 2:
Digging the Trench
Now, it’s time to dig the trench, following the marked alignment. We make sure it’s the right depth and width for the diaphragm wall.
Step 3:
Cleaning the Trench
Before moving on, we clean up the trench, removing any loose dirt and debris. This gives us a clean surface to work with.
Step 4:
Installing Stop Ends
Temporary stop ends are put in place at the bottom of the trench. They stop the concrete from flowing out when we pour it.
Step 5:
Lowering the Reinforcement Cage
Now we drop in a steel cage. This cage is key to giving the diaphragm wall its strength.
Step 6:
Pouring the Concrete
We pour the concrete into the trench, making sure it’s filled to the right level and properly compacted.
Step 7:
Removing Stop Ends
Once the concrete has set enough, we remove the temporary stop ends.
Step 8:
Excavation and Anchoring
After the diaphragm wall is in place, we dig behind it and, if needed, install anchors to keep it stable.
Step 9:
Final Adjustments
Lastly, we apply stress to the anchors and finish the excavation to make sure everything is solid and stable.
Diaphragm Walls: The Top 7 Advantages
Better Watertightness
Diaphragm walls have fewer joints compared to methods like secant walls, which helps to improve their water resistance.
Permanent Wall Structure
Diaphragm walls not only provide immediate support during construction but continue to offer long-term stability and protection.
Low Noise & Vibration
Diaphragm walls are designed to minimize noise and vibrations, making them ideal for urban areas or locations where reducing disturbance is important.
Cost Effectiveness
Their durability, multifunctionality, and ability to serve as both temporary and permanent structures often lead to significant long-term cost savings.
Exceptional Strength & Durability
Made of reinforced concrete, diaphragm walls are resistant to corrosion, erosion, and seismic forces. They can withstand high pressures and loads, and can last for decades.
Minimal Ground Movement
The manufactured Diaphragm walls effectively limit ground movement and settlement, ensuring the stability of nearby structures during excavation and construction.
Land Usage Optimization
Diaphragm walls enable efficient use of limited land by supporting the construction of deep basements, underground parking garages, and other subterranean spaces. This maximizes vertical space utilization.
