ABSTRACT

Klang Valley SBK MRT Line or now known as MRT Kajang Line has been fully operational since July 2017. This is the first MRT line in Malaysia with total length of 51 km from Sungai Buloh to Kajang. The 9.5 km underground section consists of 7 underground stations and several shafts along the alignment. Secant bored pile wall and diaphragm wall had been used extensively as permanent earth retaining wall for the underground structures.  This webinar presents the challenges of this geotechnical work during construction of 5 underground stations in addition to the South Portal cut and cover section and 3 shafts.  These challenges include work construction, ground difficulties, logistical constraint, working through existing basement structure and low head room works.  In addition, some new safety features which has been practiced in the construction industry will be discussed.

The underground stations, portal and shafts that will covered in this webinar are:

•    Merdeka Station – Diaphragm wall working with cutter in Kenny Hill formation with heavily reinforced steel cages
•    Pasar Seni Station – Diaphragm wall construction over two existing basement structures
•    Cochrane Station – Secant bored pile in limestone formation
•    Pasar Rakyat Station – Secant bored pile with the introduction of 1,500 mm diameter SBP with difficult karstic limestone formation
•    Taman Maluri Station – Secant bored pile works over existing Jalan Cheras road with difficult logistic and traffic conditions and working with low head room rigs
•    South Portal, Inai Shaft and Escape Shaft – Secant bored pile in limestone formation
•    Intervention Shaft 2 – Deeply cased secant bored pile wall in difficult ground condition and small work space
