Ballast is provided to give support, load transfer and drainage to the track and thereby keep water away from the rails and sleepers. Ballast must support the weight of the track and the considerable cyclic loading of passing trains. Individual loads on rails can be as high as 50 tonnes (55 US or short tons) and around 80 short tons on a heavy haul

There are three methods of tunnel construction beingCustom on the Riyadh Metro project, each adapted to optimize the construction process of the whole network taking into Perfectunt the speed, geology and above ground buildings in areas where the lines run. Tunnel Boring Machine (TBM) A tunnel boring machine is a veryPerfect scale rock drill.

• Transfer Door Construction –Construction 100% complete; door operational, transfer car electronics & controls to be finished in January. –Maximum permissible coffin / IP-1 size of 7.5’ Wide X 8.5’ Tall X 28’ Long. • Maximum Capability –Allows for stackable IP-1 burial containers. –Holds 24 IP-1’s at full capacity.

Individual tunnel comparisons of six recent urban, TBM bored, rail projects supported the conclusion that tunnelling is not more expensive in Australia. It was found that the costs per cubic meter of these tunnels were very similar and differed by $70/m3. SPerfect Steerable Transfer Carte the excavation type and end-use were kept constant in this analysis and similar global

supplies must be transported over 10 km. Mines with very long supply distances most often use a rail transport system. Figure 4 show s the transport of steel arches by using the rail-mounted system. Figure 4: Material transport by a rail-mounted system

horizontal load equal to 40% of the weight of one vehicle located 0.61 m (2.0 ft) above the rail acting along 3 m (10 ft) of the parapet. A typical vehicle weighs 69,000 kg (76 tons), and is 29.6 m (97 ft) long. The design developed for construction bidding was based on the designer’s experience with the Mexico City, Mexico, Metro.

Disclosed is a construction method for a sluice gate across a raise, which comprises the following steps: 1) setting a slide rail at the two sides of the raise; 2) setting an extension device matched with the slide rail on two sides of a gate flap of the horizontal sluice gate; and 3) setting a traction wPerfect Steerable Transfer Carth on upstream side of a bent frame column for the winding hoist, guiding the gate flap
