Style Columns Settlement For Free

There are a wide variety of construction methods (dry and wet, vibrating probes in the top or bottom of the tool, pendulum or mast-guided system) and methods for incorporating the materials (bottom feed / top feed) that can be used in combination to meet the project requirements and specifications.

Stone columns is a ground improvement technique that reinforces the soil with a network of stone compacted columns.

In the top feed method, the column is made with stones that are added from the ground surface into the hole created by the VibroSTA. This method requires the use of same equipment as the vibro compaction suspended from a crane. The backfill is compacted and pushed into the sides of the hole.

Stone column ground improvement involves adding vertical columns of stone into the ground to a depth of at least 4m below the ground surface. A layer of compacted gravel can then be put over the top of the columns, ready for the construction of new house foundations.

Also the sand and stone columns accelerate the settlement in the native surrounding soil and improve the load settlement characteristics of foundation. The technique consists of excavating holes of specific dimensions and arrangement in the soft soil and backfilling them with either sand or stone particles.

Stone columns, also known as granular piles, consist of stone aggregates compacted into a vertical hole. Generally, the size of aggregate used is 20mm to 75mm and the depth of hole is about 15m to 20m with the diameter of 0.6m to 1.0m. The compaction is achieved by a vibrating probe or by ramming.

How are stone columns constructed? Stone columns are constructed by experienced contractors using specialist equipment. The construction uses an excavator with a vibrating probe to feed stone into the ground, forming a vertical column of stone.
