The machine system occupies a small area of ...

Soil Types. The soil type is one of the critical factors that control the selection of a suitable compaction machine. If the soil is brought from another place to the job site, then the soil type and equipment can be selected based on the requirement to achieve a designated compaction degree.

The vibratory sand compaction piles are installed by means of standard equipment (illustrated) which consists of a P & H 255 ALC crane, a two-mass type vibrator capable of generating 22 tons of vertical force at the frequency of 700 cpm, and a pipe with a 40 cm inner diameter. Larger equipment of special design produces longer and bigger columns.

The equipment setup included the use of four 49 foot long vibrators suspended from a crane situated on a barge in order to allow for the compaction of the soil beneath 33 feet of seawater. The spacing scheme selected was a 9.8 foot by 9.8 foot center to center grid.

There is a wide range of compaction equipment. For pavements some kind of wheeled roller or vibrating plate is usually used. These only affect a small depth of soil, and to achieve larger depths vibrating piles and drop weights can be used. The applicability of the equipment depends on the soil type as indicated in the table below

Masaaki Terashi, Masaaki Katagiri, in Ground Improvement Case Histories, 2015. Sand compaction pile method. The equipment of the sand compaction pile (SCP) method resembles that of sand drain installation. When the tip is penetrated to a predetermined depth, the equipment is withdrawn, leaving a loose sand pile of predetermined length through its mandrel.

construction equipment. The strength or stability of the soil may be increased by lowering the water table and the degree of saturation of the soil. In some cases this may be accomplished by installing ditches, either permanent or temporary, prior to construction. The high contact pressures caused by construction operations on an unstable soil ...

Vibro compaction is a ground improvement technique that densifies clean, cohesionless granular soils with a downhole vibrator. It's a technique first developed by Keller in the 1930s that we've used on thousands of projects since.

Prevent frost damages and soil settlement; There are two principal types of compaction force : 01. Static Force: It is simply the dead weight of the equipment. This is done by applying the downward force on the soil surface and compressing the soil particles. Static force is confined to upper soil layers and limited to the appreciable depth.

sand compaction piles are compared with other vibro-compaction techniques such as stone columns. Methods are described for construction of sand compaction piles on land and over water. Design theories are given for the utilization of sand compaction piles at sites under-lain by both cohesionless and cohesive soils.

During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for the decrease in soil volume from the densification process. The vibratory energy reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.

The sand compaction pile method is frequently used for the improvement of soft ground. However, its driving process will induce ground vibration. In this study, in-situ measurement was conducted on the ground vibration induced by the sand pile driving at the coal ash filled ground at the ash pond in Taichung Thermal Power Plant.
