【For Warehousing and Logistics】Ram Penetration Test for Steel Frame Buildings on Limited Land
Ground investigation
A penetration test that achieves high-precision ground investigation even in narrow spaces.
In the construction of small-scale warehouses, it can be difficult to conduct ground surveys using large machinery due to limited site space and restrictions on access roads. In such situations, accurately determining the depth of the supporting layer can be challenging, potentially leading to project delays and unexpected cost increases. This service provides an optimal solution for smoothly conducting deep ground surveys even in narrow sites or locations with access restrictions, by using a compact self-propelled automatic ram sounding testing machine. 【Usage Scenarios】 - Construction sites for small warehouses in urban areas - Sites with narrow access roads - Locations where the transportation of large machinery is difficult 【Benefits of Implementation】 - Prevention of excessive pile length design - Reduction of unnecessary pile reinforcement costs - Realization of rational structural design - Assurance of reliable ground quality

basic information
【Features】 - Automatically drops a 63.5kg hammer from a height of 500mm for continuous automatic measurement of the number of impacts (Nd value) for every 200mm of penetration. - Capable of accurately assessing hard soil layers up to a maximum depth of 30m, equivalent to an N value of 50. - Automatically corrects for surrounding friction effects through measurement of rotational torque during impact. - Provides data with a high correlation to standard penetration tests. - Space-saving design with a width of approximately 830 to 1000mm and a height of approximately 2350 to 2570mm. 【Our Strengths】 Geotec offers "total ground services," providing a one-stop solution for all ground-related tasks, from ground surveys, reinforcement design, and construction for new buildings to settlement correction work for existing structures and soil contamination investigations. With extensive experience and reliable technology, we create the future of cities from the ground up.

Applications/Examples of results
It is ideal for ground surveys for the construction of mid- to low-rise steel buildings, stores, and welfare facilities in narrow sites where large heavy machinery and 3-ton unic cranes have difficulty accessing, such as flagpole lots and densely populated urban areas. In particular, it is used to confirm the depth of the supporting layer when adopting methods such as steel pipe pile construction or small-diameter steel pipe construction with end wings (e.g., CPP method), as well as for cost optimization by preventing excessive pile lengths. Additionally, it can be widely utilized in practical applications such as continuous confirmation of the inclination of the supporting layer at multiple locations as a supplementary survey to standard penetration tests, deep soil bearing capacity evaluation of uneven ground at demolition sites, and obtaining structural calculation data required for building confirmation applications.
