The French effort required 5 TBMs: two major marine machines, one mainland machine (the quick land drives of 3 km (2 miles) allowed one TBM to complete the primary drive then reverse course and complete the other), and two service tunnel machines. In distinction to the English machines, which have been given technical names, the French tunnelling machines were all named after girls: Brigitte, Europa, Catherine, Virginie, Pascaline, Séverine. On the English facet, the land tunnels were pushed from Shakespeare Cliff-the identical place because the marine tunnels-not from Folkestone. After the tunnelling, one machine was on show together with the M20 motorway in Folkestone until Eurotunnel sold it on eBay for £39,999 to a scrap metallic service provider. One constable is employed as a training officer for each initial and in-service coaching, and the power supplies all preliminary coaching not only for its own officers and staff, but also for the Port of Bristol Police and the Port of Felixstowe Police.

Whether you might be planning to install just one digital camera or multiple cameras at your home, ensure that they're positioned at the absolute best locations to provide most protection. The CCTV cameras are the types which have a entirely closed circuit and now have all its elements related collectively. On October 23, 2022, the Fars Information Agency reported the theft of the historic inscription plaque at the western entrance of this mosque, and according to the CCTV cameras around the mosque, attributed this theft to "rioters" (a time period the Iranian authorities uses to address protesters). For its entire existence, Western Canada Late Information was solo-anchored. The surveying in 1958-1959 catered for immersed tube and bridge designs, in addition to a bored tunnel, and thus a wide space was investigated. Given the previous survey outcomes and access constraints, a more southerly route was investigated in the 1972-1973 survey, and the route was confirmed to be possible. Carver and Walker each consider Disney has more evidence than it has proven, notably security footage of the world by the pool, and is protecting up knowledge of what occurred out of fear of opposed publicity.

On the French aspect, significantly close to the coast, the chalk was more durable, extra brittle and extra fractured than on the English side. The English terminal had to be located within the Castle Hill landslip, which consists of displaced and tipping blocks of decrease chalk, glauconitic marl and gault debris. A 25-30 m (82-98 ft) layer of chalk marl (French: craie bleue) in the lower third of the lower chalk appeared to current the very best tunnelling medium. On the English side, the stratum dip is less than 5°; on the French facet, this will increase to 20°. Jointing and faulting are current on each sides. The Quaternary undersea valley Fosse Dangeard, and Castle Hill landslip at the English portal, prompted considerations. Recognized by the 1964-1965 geophysical survey, the Fosse Dangeard is an infilled valley system extending 80 m (262 ft) below the seabed, 500 m (1,640 ft) south of the tunnel route in mid-channel. A 1986 survey showed that a tributary crossed the trail of the tunnel, and so the tunnel route was made as far north and deep as potential.

The 1964-1965 surveys focused on a northerly route that left the English coast at Dover harbour; using 70 boreholes, an space of deeply weathered rock with excessive permeability was situated simply south of Dover harbour. A 900 mm (35 in) gauge railway was used on the English side during building. On the French facet at Sangatte, a deep shaft with adits was made. Thus the area was stabilised by buttressing and inserting drainage adits. On the English aspect, the easier geology allowed faster open-faced TBMs. This minimised the impact to the bottom, allowed high water pressures to be withstood and in addition alleviated the necessity to grout ahead of the tunnel.

On the French side, neoprene and grout sealed bolted linings made from cast iron or high-energy bolstered concrete have been used; on the English side, the principle requirement was for speed, so bolting of solid-iron lining segments was solely done in areas of poor geology.
