Construction of Upstream Coffer Dam Over Jet Grouted Barrier for Teesta VI HEP, Sikkim
The balance work at the Teesta VI Hydro Electric Power Project requires construction of the reinforced diaphragm wall along with watertight upstream coffer dam construction towards the right embankment of the existing barrage. The soil profile at the barrage location is mainly made of large sized boulders and river born material deposited over a period. The subsoil consisting of boulders to be drilled to depths of 36 m below ground level for installation of Jet Grouted Columns. Trails columns are installed before start of the main works of diameter 1.4 m, 1.6 and 1.8 m to establish the parameters of the main works. The jet grouted columns are installed to create a watertight barrier on the upstream side beneath the cofferdam for contraction of the diaphragm and protect the barrage from the underground seepages. Symmetric predrilling with air-driven DTH and casing OD of 152 mm and ID 133 mm casing are used for drilling. Dulex Double Water system (W/B) was used for the installation of jet grouting columns. This paper discusses the installation of the trail jet grouting columns and execution of the main works through the boulder soil profile in the lower Himalayan regions.
