Project Description
One of the greatests applications of the Menard Vacuum technique, developed by Menard, took place near Pusan, the second largest city in South Korea.
The town of Kimhae, 20 km west from Pusan, decided to build a new sewage treatment plant to carry out the treatment of the wastewater of more than 500,000 inhabitants. This new 80,000 m2 large plant is located on compressible sediments, mainly clay and silt, which are between 20 and 50 m thick.
Sangjee Menard, joint venture between Menard and Sangjee Co Ltd, won in 1995 the soil improvement contract, thanks to a solution using the Menard Vacuum technique.
The results observed on the Kimhae building site from January 1995 to May 1997, thanks to the execeptional nature of the site, are still unrivaled and the site is used worldwide as a reference example in the field of consolidation. The maximum final settlement obtained was about 5.50 m, which corresponds to the height of a two-story building! The loading tests performed after the plant construction have confirmed the complete success of the method and the Menard engineers' perfect technical execution.
The Kimhae sewage treatment plant has been in service since January 2000.
