Hydraulic Diaphragm Wall Grab

Working Principles of Hydraulic Diaphragm Wall Grab
1. SG series hydraulic diaphragm wall grab is widely used for making guide walls.
2. The machine digs along the guide wall, while it is using the inclinometer to measure the verticality.
3. Hydraulic diaphragm wall grab constantly adjusts the grab verticality to ensure the wall with high precision.
4. Slurry should be used to protect the wall from collapse.
5. Finally, our hydraulic diaphragm wall grab cleans the wall bottom, place the cage and then concrete the cement.

Features of Hydraulic Diaphragm Wall Grab
1. Our hydraulic diaphragm wall grab operates with no vibration and low noise. Hence it can even work at night.
2. Good penetration resistance is one of its featured properties.
3. The wall made by our hydraulic diaphragm wall grab could bear huge side pressure, which effectively avoids groundsill sinking and landslip.
4. Soil retaining, water stealing and weight bearing functions are all available. Thus, our wall grab is cost saving.
5. Electron detector, inclinometer and hydraulic push-plate are equipped to control the depth and verticality.
6. Our hydraulic diaphragm wall grab can be used as the rigid foundation to replace shafts, and other foundation.
