Malaysia Metro Project

Sandy mud stone, flaky mudstone, etc.

TBMCREC-50 and TBM CREC-51 with boring diameters 6670m and main drive power 1120KWhave been supplied to Malaysia Kelang Valley MRT Line and the geology thereofis characterized by sandy mudstone, flaky mudstone, HW mudstone, crush edg ravel, and Kenny Hill eluvium. This interval is very complex and rich in underground water, furthermore, buildings and/or structures which are required to be crossed are quite many. TBM CREC-51 achieved highest monthly advance of 347.2 meters which hit Malaysian tunneling record. The final settlement andupheaval are controlled within 2mm.
