CR112 - D-wall excavation commences

 

19 August 2022 - The hydrofraise machine in position & in action excavating the diaphragm wall
trench.

This past week, excavation works commenced at Hougang station as part of works to install diaphragm walls (d-walls) to support station construction works. As part of the works, the hydrofraise machine is used to lower down the vertical cutters which rotate to remove soil. The excavated area is prevented from collapsing through the use of betonite slurry, a dense liquid that is pumped in by the machine from storage reservoirs. Do check out the videos which explain the process.

It's been a few months since we last came by here. Things are definitely ramping up with so much going on at the site. Machines coming in, set up work going on, reconfiguration works and exit & road closures are all in full effect. The construction site can be broken into about 3 smaller zones - along Pasir Ris Drive 8, Pasir Ris Central & Pasir Ris Street 51.

CRL2 - Speculated Station Locations

As it has been more than 2 years since Cross Island Line (CRL) Punggol Extension was announced, we are expecting news of the next phase of the line to be announced this year. With an expected completion date of 2032, we foresee tenders for advanced contracts to be published soon. Earlier in June, pre-qualifications for 8 contracts for the second phase of the line were called for.

The Urban Redevelopment Authority (URA) also published the latest Long-Term Plan in June 2022 which showed the notional full alignment of the CRL. By overlaying the long-term plan map over a geographic map, we were able to collaborate the supporting data and information with the latest sightings of soil investigation works to compile a list of probable station locations for the CRL2 section. This section of the CRL will continue from the tunnel section directly crossing below the Central Catchment Nature Reserve (CCNR), and ends at Jurong Lake District.

We expect that there will be a total of 6 stations in this section, which stretches over 15km consisting of 5km below the CCNR, and 10km of tunnels between the 6 stations.
