KPE - Kallang-Paya Lebar Expressway
The Problems
Tunnels are used in the transportation sector for conveyance of highway and railway traffic. They also serve as a means of conveyance of water in irrigation and hydroelectric power projects. During construction of tunnels variation of strata is often encountered. This poses various problems in tunneling. Also, the decision regarding the support system required for various strata is critical to ensure trouble free construction. As the geological formation for each tunnel project is usually very different and all scientific studies are carried on a project specific basis, tunneling in a new formation remains an art than a science wherein the designers rely on intuition and previous experience to effectively solve problems.
Like all concrete structures, waterproofing system to this tunnel is crucial. On the other hand, to ensure the waterproofing system being installed properly is also an important factor to determine the future effectiveness of the system.
In this project, the major problem is that it is a long tunnel that passes through a wide range of strata in different ground level. Moreover, it requires a massive traffic diversion and therefore designers always have the desire to keep the construction time to be as short as possible. In view of this, waterproofing system, being one of the critical paths in the construction program, places a very important role in the control of construction period as well.
