Ram penetration test for small steel buildings aimed at commercial facilities.
Ground investigation
Supporting store expansion with high-precision ground surveys even in narrow spaces.
In the expansion of commercial facility stores, a safe and reliable construction plan is required even when there are constraints such as limited land and narrow front roads. Particularly in the construction of steel frame buildings on small sites where large machinery cannot be brought in, accurately understanding the depth of the supporting layer becomes a challenge. This service utilizes a compact self-propelled automatic ram sounding testing machine, providing an optimal solution for smoothly conducting deep ground investigations even in such environments. This helps prevent excessive pile length design, reduces unnecessary pile reinforcement costs, and achieves a rational structural design, delivering ground quality that ensures safety and trust. 【Usage Scenarios】 - Store expansion in small urban lots - New store construction in areas with narrow front roads - Expansion work adjacent to existing buildings 【Benefits of Implementation】 - Ground investigation possible in limited spaces - Reduction of unnecessary pile reinforcement costs - Achievement of rational structural design - Assurance of safe and reliable ground quality

Applications/Examples of results
It is ideal for ground surveys for the new construction of mid- to low-rise steel buildings, stores, and welfare facilities in narrow sites, flagpole lots, and densely populated urban areas where large heavy machinery and 3-ton unic cranes have difficulty accessing. 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 wing tips (CPP method, etc.), 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 necessary for building confirmation applications.
