Ground Improvement by Dynamic Compaction

  Dynamic compaction (DC is a highly effective soil improvement technique used to increase the load-bearing capacity and reduce the settlement of weak or loose soils. It involves the application of high-energy impacts to the ground surface using heavy machinery. This process densifies the soil and improves its overall strength and stability.

Rapid Impact Compaction (RIC) is a soil improvement technique designed to quickly and efficiently increase the bearing capacity of shallow soils. It involves the use of specialized machinery that delivers repeated impacts to the ground surface, compacting the soil layers and improving their load-bearing characteristics.

 The technique of High Energy Impact Compaction (HEIC) involves the application of high energy impulses at the ground surface utilizing rollers which are usually triangular, square, or pentagonal in shape. These rollers are towed by means of a tractor. Adoption of this technique enables compaction to depths greater than can be achieved by utilizing conventional circular rollers.

The CPT crawler has been designed to execute soil mechanical research in an efficient manner. By means of the penetrometer pusher, installed in the center of gravity of the CPT crawler, an electrical or mechanical probe (called a cone) is pushed into the ground and the mechanical resistance and friction of the soil is recorded. The CPT crawler has a relatively high self-weight and serves as a counterweight to provide the required penetrative force.
