Jakarta \u2013 PT Hutama Karya Infrastruktur (HKI) has once again achieved success in innovation. In mid-December 2022, HKI won first place in the Road and Bridge Technology Innovation Video Competition held by the Directorate General of Highways, Ministry of Public Works and Public Housing (PUPR) in celebration of National Road Day 2022. The award ceremony took place during the peak event on Wednesday, December 20, in Megamendung, Bogor. The award was presented by Dr. Ir Hedy Rahardian, M.Sc., the Director General of Highways, and was received by Mutiar Warman, Head of HKI Engineering and Design Department.<\/p>\n
The innovation presented in the competition video was the use of Full Displacement Column (FDC) in the Padang-Sicincin Toll Road project. FDC is a rigid inclusion method, also known as KGM (Kolom Grout Modular), designed to prevent toll road damage due to soft soil conditions.<\/p>\n
This method involves drilling holes and penetrating the soil layers without bringing the drilled soil to the surface. Once the drill reaches the planned depth, strengthening material in the form of cement grout\/mortar\/concrete is injected through the tool's RSA. The combination of densification from the drilling process and soil reinforcement with grout material increases the soil's stiffness modulus. Compared to other soil improvement methods, FDC can be applied in various soil types, including gravelly sand, sand, silt, clay, and even soft organic soils, as long as the soil can be displaced or compacted. The FDC method enhances the friction of reinforced concrete columns and helps reduce soil settlement, consolidating the ground, and lowering soil compressibility, thereby decreasing the potential for liquefaction.<\/p>\n
Selo Tjahjono, Director of Operations III, explained that FDC implemented in the Padang-Sicincin Toll Road project helps address soft soil issues often encountered in the field. \"We use FDC to mitigate soft soil settlement and to prevent liquefaction in loose silty sand. Additionally, FDC improves the slope stability at the site,\" Selo said.<\/span>\u00a0<\/span><\/p>\n He further added that receiving this award motivates HKI to continue innovating in the construction of roads and bridges. \"We are grateful for this award on National Road Day 2022. We hope that in the future, HKI can continue to build high-quality roads and bridges using appropriate and beneficial technologies to connect regions across Indonesia,\" concluded Selo.<\/span>\u00a0<\/span><\/p>","protected":false},"excerpt":{"rendered":" Jakarta \u2013 PT Hutama Karya Infrastruktur (HKI) has once again achieved success in innovation.
