Control Columns Settlement For Free

The construction methods to reduce the post-construction settlement as follow. One is subgrade treatment method, such as controlling the type of the filler and the depth of each layer, etc. Another is foundation treatment method. This method is commonly used on the treatment of foundation.

Improve the strength and stiffness of the building If we create a resistant structure using chains, reinforcement, boxed beams, reinforced concrete walls, etc., further differential settlements are prevented or reduced to negligible levels. However, the stiffness will create new changes in the pressures on the soil.

You should avoid soils that are soft, loose, expansive, compressible, organic or contaminated. These soils can cause uneven settlement, heave, subsidence or contamination of the foundation. You should also consider the soil moisture content, as changes in water level can cause swelling or shrinkage of the soil.

Underpinning Underpinning is a method to prevent the foundations from further settlement. The method involves the strengthening of the foundation by transferring the load to deeper strata. The foundation is clubbed with pins embedded in the deeper ground. Underpinning is often done in conjugation with the shoring.

Soil treatment methods include: Grouting. Soft soil consolidation with surcharge combined with vertical drains to accelerate compaction, Dynamic compaction, Replacement of soft soil with strong fill materials, Lime and cement columns, Electroosmosis, Freezing technique, Blasting,

Methods of prevention and remediation of the consequences of differential settlements Foundation remediation by concrete underpinning. Foundation remediation with jet grouting. Foundation remediation with micro piles. Foundation remediation by using expanding geopolymers.

Note: the consolidation settlement can be reduced by conducting any of the following: 1. Increase the length of piles (when the length of piles are increased, ?H? value in the preceding equation would reduce. ?H? is the thickness of the compressible portion of the clay layer).
