Site Investigation | Ground Bearing Capacity Evaluation and Optimal Foundation Selection to Prevent Uneven Load Settlement of Energy Storage Containers
Boring survey
Prevent uneven settlement of battery storage containers! Directly measure shallow soil bearing capacity through plate load testing to achieve optimal foundation design that avoids excessive reinforcement.
The introduction of container-type storage batteries on factory premises raises concerns about localized ground subsidence and differential settlement due to uneven distribution of internal equipment. Geotech's ground bearing capacity evaluation service conducts plate load tests in the shallow layers of the installation site, directly and accurately calculating the ultimate bearing capacity and ground reaction coefficient under load. By visualizing and analyzing the settlement behavior in millimeters due to uneven ground pressure, we can avoid excessive steel pipe piling and deep ground improvement, allowing for the selection of optimal direct foundation specifications such as mat foundations based on solid evidence. Even in operating factory sites or narrow vacant lots, we can arrange speedy testing by leveraging our mobility, providing reliable design evidence under strict safety management. Through our unique wide-area ground database "GEODAS" and comprehensive analysis by qualified technical experts, we also facilitate the smooth review process for building confirmation applications, enabling the construction of safe and cost-effective storage facilities.

basic information
According to the Geotechnical Engineering Society Standard JGS1521 (Method for Plate Load Test on Ground), a steel circular loading plate (diameter 300mm) is placed on the ground surface for loading. Heavy machinery, which ensures its own weight, is used as a reaction device, and the load is controlled in stages using a hydraulic jack and a load cell. Four displacement gauges are arranged at equal intervals to automatically collect and record the settlement amount in units of 0.01mm. Through multi-stage loading (such as 5 cycles), the ultimate bearing capacity, long-term and short-term allowable bearing capacity, as well as the ground reaction coefficient Kv value and deformation coefficient E0 value are identified. Calibration equipment management compliant with ISO9001 and data verification by qualified personnel (such as geological survey engineers) are thoroughly implemented.

Applications/Examples of results
It will be directly utilized for determining ground support capacity and measures against uneven load settlement when installing container-type storage batteries within factories. It is optimal for evaluating allowable ground pressure for floor slabs and mat foundations during the expansion of substation and self-generation facilities, as well as for determining the unnecessary need for excessive piling or ground improvement. It will precisely verify the feasibility of foundation reinforcement for outdoor aluminum cartridge installations and high-density storage systems. It contributes to creating a safe foundation for the construction of various industrial energy plants, such as conducting ground bearing capacity surveys when repurposing parking lots and green spaces within operating factories into storage yards, and generating structural selection grounds for building confirmation applications.
