The concrete (usually with steel bar) is poured directly into the stable and solid roadbed, and the new line of ordinary sleeper and gravel bed is not used. This kind of line is clean, suitable for large volume and difficult maintenance area, especially for tunnel, underground railway, port wharf and stone road base. But its construction investment is big, if because of the construction slapdash or basement instability, concrete layer fracture, cure difficulty. China's overall Taoist route in the tunnel is more than 300 kilometers long
It is also known as welding long rail line, which is a kind of line that welded normal rails without rail seam. The welding rail is not less than 200 meters long, and the actual application is usually 800~1000 meters or more. The long track is laid in the specified temperature range and fixed on the pillow. The long rail ends with a rail joint, while the middle part cannot scale up and down with the temperature. Therefore, there will be a great temperature pressure in the middle of the rail during the summer, which will produce a great temperature tension in winter. The greatest pressure on the rail and tension according to the years of rail laying and the highest temperature and minimum temperature calculation, rail tracks the maximum pressure should not cause to drum up by maximum tension should not cause rail fracture
Protocol timing indistinguishable from the real VAG/VAS tool. Works reliably even with “difficult” control modules for example the 1991-1994 1Z Audi TDIs along with the 1993-1994 Audi 2.6L with Hella ECU. Built-In VAG-Saver functionality — instantly alerts an individual if either the K/K1 line or L/K2 line is shorted to Ground or Vbatt.
To restore the original driving block method;
Wide provided suitable for busy trunk, also can be laid in tunnel and station floor maintenance difficulties, stone or soil subgrade are laid, but the mud pumping in the diseases of roadbed must be laid on the roadbed diseases after renovation. The main advantages of the wide sleeper circuit are: the suborbital sinking is small. The vibration acceleration is smaller than the concrete sleeper line, which gradually slows down and stops after laying. So the line maintenance work is greatly reduced, about a third of the general concrete sleeper line. The track is easy to keep clean. Dirt is not easy to break into the bed and prolong the repair cycle of the route. The line is smooth and stable, which is conducive to high-speed operation and the laying of seamless circuit. The disadvantage is that the cost is higher, and it is more difficult to change the shop on the busy trunk line
