What we are doing
What we are doing
We have built a conveyor system to move earth excavated from the two tunnels at West Ruislip Portal to the treatment area, south of the Chiltern railway line near Harvil Road. The area is shown on the map overleaf.
The conveyor is an elevated rubber belt system supported on free spinning rollers. When fully operational, it will significantly reduce the number of lorry movements and improve the volume of traffic in the area.
Following an initial period of testing, it will become operational in June 2023. The conveyor will be enclosed to reduce noise and dust. It will operate 24/7 in support of the continuous tunnelling activities.
Testing
We will undertake testing of the conveyor system from 1 to 14 June 2023. This will help to ensure that it works safely and effectively and will allow us to monitor and manage the level of noise that this activity may cause.
Testing of the conveyor will be carried out between 8am and 6pm, Monday to Saturday and if required on Sunday. There is a safety alarm that will sound like a claxon each time the belt starts and stops. This is a health and safety legal requirement that we must follow. This alarm is part of the testing phase and will be heard frequently throughout the testing period with each start and stop of the belt.
We will not begin full use of the conveyor until all tests are complete and we have taken appropriate measures to mitigate potential noise impacts.
Operation
Following testing, the conveyor will become fully operational and will run 24/7 until the completion of the tunnelling works, approximately June 2025.
• What you will see
The conveyor is largely at ground level and located behind the site boundary, except where it crosses the bridges over the River Pinn, Breakspear Road South, the Chiltern railway line and the internal rail bridge at West Ruislip Portal. The entire length will be enclosed to control noise and dust. It will have low level lighting for safe maintenance access. The outdoor sections lighting will be turned off during daylight hours. The enclosed bridge sections will be continually lit due to the lack of natural light.
• What you will hear
The expected operational noise will be a low-level humming noise generated by the belt running on the rollers. The electric drive motors for the conveyor are located near the Treatment Area north and south of the Chiltern railway line. We have carried out noise modelling for the conveyor to ensure that it is within the permitted levels. Once it is fully operational, we will monitor the noise levels and take appropriate mitigating measures where noise can be further reduced.
The safety alarm will operate as described above for maintenance or stoppages in tunnelling.
