Settlement Analysis due to Micro-Tunnelling Works

Underground sewage system has been designed with a view to modern man’s
inclination toward health, hygiene and his aversion to filth and pollutants. Currently
there is on-going project at Ipoh, Perak. It is a project to build a sewerage treatment
plant and sub-catchment pipeline network across Ipoh City. Underground pipe usually
installed using open-trench method but in this project, the pipe was laid down using
trenchless method. Trenchless method involved the use of micro-tunnelling technique.
This disquisition is intended to analyse the longitudinal settlement and transverse
settlement induced by the micro-tunnelling activity of the 1050mm and 1500mm
diameter sewage pipeline at Jalan President Kennedy, Pasir Puteh and Jalan Sri Kinta
1 Ipoh, Perak. A ground level movement were monitor closely using marker placed at
the activity location.
