GUEST SPEAKER : THE ROLE OF CIVIL ENGINEERING MASTERS (GEOTECH AND HIGHWAYS) IN INFRASTRUCTURE DEVELOPMENT
On Saturday, 20 August 2022, Mr. Dandung Sri Harninto, ST., MT., IPU., as the main director of PT. Geoforce Indonesia had the opportunity to become one of the presenters at a guest lecture organized by the Islamic University of Riau's Civil Engineering Masters Study Program with the theme The Role of Civil Engineering Masters (Geotech and Roads) in Infrastructure Development.
On his occasion, Mr. Dandung explained several important discussions including regarding Alternatives to Construction of Retaining Walls and Slope Improvements Using Geosynthetic Technology as well as discussions on Prefabricated Vertical Drain (PVD), Prefabricated Horizontal Drain (PHD), Double Vacuum System, and Monitoring of Geotechnical Instrumentation. The use of PVD aims to accelerate the release of pore water so that the soil consolidation process occurs more quickly. Soil criteria in question are soft clay, low carrying capacity, and compressible (capable of being compressed). PVD serves to shorten the water travel distance in the soil pores, because water will flow laterally to the nearest canal. This can reduce the time it takes to compact the soil.
Furthermore, there are two alternatives available for Earth Retaining Wall Innovations with Geosynthetic Technology, namely Concrete Facing Geoforce Segmental Retaining Wall (GSRW) and Facing Green using Geoframes. The GSRW system can be used on flyover oprits and is considered to be more effective, efficient and economical because it uses relatively thin concrete panels and a much lighter structure compared to conventional methods. Besides that, the Facing Green or Geoframe system can also be a very safe alternative for high embankment stabilization if it is designed according to standards. Facing Geoframe is made of galvanized iron frame which can later be planted with vines so that it looks neater, beautiful and environmentally friendly. The use of the Geoframe system also has other advantages, including a fast installation process, very competitive prices, and very flexible products.-
