About This Project
Murphy Surveys was contracted to carry out emergency track monitoring of a 100m section of twin track following a land slip in the embankment near Battle in the South of England. The slip was caused by sustained and heavy rainfall in the month of February of 2014 which caused significant issues throughout the UK rail network.
- Our immediate requirement was to install targets onto both sets of running rails at 3m centres either side of the centreline of the slip. Due to the urgent nature of the project we mobilised a team to the remote location and installed the targets within 18hrs of the initial call.
- We utilised rail clips to quickly attach the targets to the web of the rail. The top of rail level was surveyed at each target position to determine the offset from the target to the rail level and calculate the cant between adjacent points as well as the twist along each line.
- Daily monitoring was carried out for a duration of 5 months with results issued to the client within 24hrs in graphical and tabular form in an Excel Spreadsheet.
- A topographic survey was carried out of the area surrounding the site to assist with the design of remedial works to prevent slippage in the future.
