Diaphragm Wall Construction
Rana Pratap Construction is a Infrastructure Geotechnical Ground Engineering Projects Company specializes in Diaphragm wall construction work involves the excavation and installation of a deep and continuous wall structure known as a diaphragm wall or slurry wall. This construction technique is commonly used in civil engineering and construction projects, such as underground structures, deep foundations, and retaining walls. Diaphragm walls are typically made of reinforced concrete and are used to provide structural support, prevent groundwater infiltration, and act as a barrier in various construction applications.
Diaphragm wall construction work is performed by various construction companies, engineering firms, and contractors around the world. These companies specialize in various construction techniques, including diaphragm wall construction, and they may undertake projects in the field of civil engineering, infrastructure development, and construction.
The construction process of diaphragm walls typically involves the following steps:
Excavation: A trench is excavated using specialized equipment such as grab excavators, hydromills, or slurry wall grabs. The excavation is often done in sections, and bentonite slurry or polymer slurry may be used to support the trench walls and prevent collapse.
Reinforcement: Steel reinforcement cages or rebar cages are lowered into the trench. These cages provide structural strength to the diaphragm wall.
Concrete Placement: High-quality concrete is poured into the trench to form the diaphragm wall. Tremie pipes or other methods may be used to ensure the proper placement of concrete without disturbing the slurry.
Slurry Removal: After the concrete has cured, excess slurry is typically removed from the trench, and the wall is allowed to set and harden.
Diaphragm walls are commonly used in projects like deep basements, underground parking structures, tunnels, and deep foundations for buildings and bridges. These walls provide stability, prevent water ingress, and serve as structural elements in various construction applications.
