In the scope of Doha Metro Gold Line Project, curtain grouting is planned for reduction of the groundwater inflow during the construction phase . In order to achieve that various numbers of both vertical and inclined (up to 18° from vertical) boreholes are drilled down to 36m depth and grouted bottom up by single packer grouting method at 5m long stages having 10 to 2 bars of descending pressure criteria.
In the scope of DP World Yarımca Container Terminal project below listed works are completed
successfully, Geotechnical Design of project is prepared and approvals are received From Consultant and IDV ,Trial JG Designs are carried out and JG parameters are selected , A total 14 954 nos JG columns are constructed with a total of 261.314 m Jet Grouting , Performance Load tests on Single Columns are carried out ,Multi Column Load tests are carried out on selected group of Columns, Visual checks , Rotary corings and UCS tests arecarried out at selected columns, PIT tests are executed on selected columns ,CPT tests are carried at selected zones.
87 bored piles with dia of Ø2000mm, each having a length of 45-70m were constructed by reverse circulation drilling.
