Site Investigation | Investigation to Identify Support Layers in a Small Steel Building Where Large Heavy Machinery Cannot Enter
Supports the construction of steel frame buildings in urban areas with limited space where large heavy machinery cannot enter! Automatically measures deep supporting layers with automatic ram sounding tests.
In urban areas, the construction of steel frame buildings on narrow plots often faces challenges due to site width and restrictions on the delivery of large boring survey machinery. The "Automatic Ram Sounding Test" proposed by Geotech utilizes a compact self-propelled survey machine with a width of just 830 mm, enabling smooth surveys even in tight spaces and sites with delivery limitations. Equipped with an automatic continuous penetration mechanism using a 63.5 kg hammer, it can continuously advance and measure through hard layers exceeding an N value of 30, which traditional SWS tests cannot address, as well as deeper layers. Additionally, by automatically acquiring the number of blows (Nd value) and rotational torque every 200 mm of penetration, it corrects for the effects of side friction and calculates highly accurate ground data that correlates well with the N value from standard penetration tests. Since there is no need to assemble scaffolding, installation and removal are easy, allowing for rapid verification of bearing layers while significantly reducing costs. This greatly contributes to the safe design of pile foundations and the efficiency of processes in the construction and renovation of steel frame buildings in urban areas.
