Jacking
Hydraulic jacking in construction is a method used to lift heavy structures, buildings, or equipment by applying hydraulic pressure to raise them off the ground. It’s a common technique employed for various purposes in the construction industry.
Jacking In Construction
1
Foundation Repair
Hydraulic jacking is often used to lift and level foundations that have settled or sunk unevenly due to soil subsidence or other factors. This process involves inserting hydraulic jacks beneath the foundation and gradually raising it to its desired position.
2
Building Elevation
In flood-prone areas or regions at risk of rising sea levels, hydraulic jacking can be employed to elevate existing buildings to a higher elevation to protect them from potential water damage.
3
Heavy Equipment Installation
Hydraulic jacking systems are used to safely and precisely position heavy equipment, such as large industrial machinery or generators, during installation.
4
Modular Construction
In modular construction projects, hydraulic jacking is used to lift and assemble pre-fabricated sections of buildings, allowing for quicker and more efficient construction.
The Process
1
Assessment
Engineers assess the structure or equipment to determine the lifting points and the amount of force required.
2
Jack Placement
Hydraulic jacks are strategically placed beneath the load-bearing points of the structure or equipment.
3
Hydraulic Pressure
Hydraulic fluid is pumped into the jacks, creating pressure that pushes against a piston. As the pressure increases, it lifts the load.
4
Monitoring
Throughout the lifting process, technicians closely monitor the pressure, ensuring that the structure is raised evenly and safely.
5
Support & Adjustment
Temporary supports may be used to stabilize the lifted structure, and adjustments are made as needed to achieve the desired height or levelness.
6
Lowering
Once the necessary work is completed, the hydraulic pressure is gradually released, allowing the structure or equipment to be lowered back to its original position or a new one, if required.
