Dry ground improvement method using sand and solidifying material for columnar body insertion (patented method)
In the "Pre-Compressed Sand Pile Method," an eccentric spherical wing at the tip is rotated, and specially prepared sand with adjusted grain size for compaction is supplied from the ground surface, being driven in with a horizontal pressure of approximately 500 kN/m². This reduces the voids in the surrounding ground in a cylindrical shape, compacting it. It is a method that does not contaminate the soil and supports structures over a surface area. It can reduce the stress applied to the foundation's lower part. 【Features】 ○ Applicable soil: Clayey soil, sandy soil Wsw≧0.50(0.25)kN ○ Construction noise: Engine noise (low) ○ Construction water: Not required ○ Generated soil: None For more details, please contact us or download the catalog.

basic information
【Features】 ○ Environmentally friendly with no vibration and low noise → During construction, there is only the sound of the machine operating, with no impact noise or vibration like that of a pile driver. ○ Saves time and costs → No need for soil disposal or head treatment that was traditionally required. → As a result, time and costs can be saved. → After construction, it can be treated as a good foundation for normal use. ○ Outstanding long-term bearing capacity → Compared to the usual required ground bearing capacity of 20KN/m² to 50KN/m², a maximum bearing capacity of 70KN/m² can be achieved with a construction interval of 2m or less. → The effectiveness of the densified ground lasts semi-permanently. ○ Can be constructed in narrow spaces → The compact equipment allows for construction in tight areas. ○ Resistant to vibrations and gentle on buildings → By supporting buildings on a surface, the ground solidifies in three dimensions, reducing traffic vibrations and preventing excessive stress on buildings during vertical shaking from earthquakes. ○ Can be constructed even before the building plan is finalized → In multi-building sites, a rough range can be determined even before the building plan is decided, allowing for preemptive construction improvements. → It is very economical as the entire site can be improved at once. ● For more details, please contact us or download the catalog.
