Ground investigation | Ground investigation to confirm the bearing layer in a narrow steel building with transportation restrictions.
Perfect for alternatives to boring! We reliably confirm deep support layers through automatic ram sounding tests in steel frame buildings with limited access on narrow sites.
When constructing a steel frame building on a small site in an urban area, traditional boring standard penetration tests often face challenges such as securing installation space, high investigation costs, and long temporary periods, making their implementation difficult in many cases. GeoTech's "Automatic Ram Sounding Test" utilizes a super compact self-propelled crawler machine with a width of only 830 mm, allowing for easy self-propelled entry and setup even in sites with limited access routes and working space. Equipped with a fully automatic striking mechanism using a 63.5 kg hammer, it can penetrate hard layers with an N value exceeding 30, which cannot be reached by SWS tests, allowing for excavation up to around 30 meters deep. By measuring the number of strikes and simultaneously measuring the rotational torque to accurately correct for the effects of surface friction, it calculates highly precise ground strength data with correlation equivalent to that of boring tests. The use of dry construction without water and the reduction of the need for large scaffolding assembly minimizes the effort for temporary setup and removal, enabling verification of the bearing layer with overwhelming short construction periods and low costs compared to boring investigations. This effectively mitigates delays in the construction process and budget overruns for steel frame buildings in small urban sites.
