Pile Construction

1. Boring: To ensure accurate boring of the pile, four reference points should be established, forming two perpendicular lines, with each point located 1.5 meters from the pile center. Initially, bore a 2-meter depth using a cutting tool of the desired pile diameter. Subsequently, continue boring as per sub-soil investigation report, employing a liner, Bentonite, or a combination as needed. A temporary guide casing, app. 2 meters in length with an outside diameter matching the nominal pile diameter, should be lowered into the borehole. Ensure that the diameter of the cutting tool is slightly smaller, up to a maximum of >75 mm the outside diameter of the casing, to allow free movement within the casing during operation. Check and adjust the position and alignment casing of guide with respect to the fixed reference points around location of pile to avoid deviation from the exact pile location. Boring should proceed upto the the hard strata where foundation is placed as specified in th...

All about Pile Foundation

Image
Pile foundation is a category of deep foundation. Deep foundation is used when soil strata beneath the foundation is not capable of bearing the structural load. Pile foundation rests on the hard strata well beneath the soil. When to use: When the surface or near-surface strata are highly compressible and weak, making them unable to support the structural loads, pile foundations are needed. These piles transfer structural loads through weaker layers to more stable, deeper strata.  Pile foundations are also utilized to resist horizontal forces in addition to vertical loads.  They are essential for structures like transmission towers and offshore platforms that experience uplift forces.  Additionally, in areas with expansive soils, such as black cotton soil, which undergo significant volume changes with fluctuations in water content, piles are employed to transfer loads below the active zone.
