Ground Investigation | Ground Bearing Capacity Evaluation Method for Narrow Sites to Prevent Uneven Load in Factory Energy Storage Containers
A storage battery container installed in a small area of an operating factory! Achieving direct foundation construction that minimizes excessive reinforcement through space-saving ground bearing capacity evaluation to prevent uneven load settlement.
When installing container-type storage batteries in narrow spaces between buildings or within the operational area of a factory, difficulties in transporting large survey equipment and uneven weight distribution of the storage units pose significant challenges. The ground bearing capacity evaluation service provided by Geotech employs a plate load test that allows for space-saving construction, accurately measuring the shallow support strength of the foundation installation surface and the ground reaction coefficient, even in confined areas. By quantifying the ground's resistance to localized ground pressure without being constrained by installation space, we eliminate the risk of tilting accidents and structural distortion due to uneven loading in advance. By presenting objective measured parameters, we eliminate excessive piling and ground improvement that lead to soaring transportation and construction costs, enabling the adoption of optimal direct foundations, including mat foundations. With strict on-site safety management by qualified technical experts and a precise analytical system, we also smoothly support the review of building confirmation applications, providing comprehensive assistance for the safe and smooth expansion of the factory's energy infrastructure.
basic information
We will conduct a plate load test in accordance with the Geotechnical Engineering Society Standard JGS1521, using a space-saving equipment layout. A steel loading plate with a diameter of 300mm and a hydraulic jack will be installed, and we will perform multi-stage loading and unloading in five or more stages using the weight of small machinery secured on-site as the reaction force. The amount of settlement will be automatically measured with millimeter precision using a displacement gauge, allowing for the direct calculation of ultimate bearing capacity, long-term and short-term allowable bearing capacity, ground reaction coefficient (K value), and deformation coefficient (E value). High-precision calibrated measuring instruments will be used, and under an ISO9001 certified system, qualified professionals such as geological survey engineers will consistently carry out quality control and technical analysis of the data.

Applications/Examples of results
The evaluation of ground bearing capacity and measures against uneven loading for the installation of container-type storage batteries in narrow areas where large heavy machinery has difficulty accessing, such as gaps between buildings within operating factory premises and outdoor parking lots, is optimal. It can be used for determining the adoption of direct foundations (flat foundations and slab foundations) in narrow yards with restricted access routes, checking allowable ground pressure, and verifying the risk of localized settlement due to uneven loading. Additionally, we offer cost optimization proposals aimed at reducing temporary construction costs and ground reinforcement expenses associated with narrow site construction, as well as the submission of ground bearing capacity documentation to confirmation and review agencies, flexibly addressing on-site challenges related to the expansion of existing factory facilities and the development of energy infrastructure.
