Bridge and culvert joints plugging plugging Hotline: 13961999789 tunnel refers to existing buildings or structures dug earth and rock channel, for three-dimensional transportation, through the mountains, underground passages, the river, over the sea, pipelines, underground cables , water conservancy and other uses. Underpass tunnel are not necessarily all, only on the ground under the known underground tunnels. Tunnel - Tunnel Many species classification, according to zoning, railway tunnels, rail-cum-tunnel, subway tunnels; divided by cross-sectional shape, a circular tunnel, arched tunnel, tunnel oval, rectangular tunnels; by location points, hillside tunnel, uphill tunnel, underwater tunnels and underground tunnels; by lining structure points, tunnel lining the wall, curved wall lining tunnels, curved sidewall called invert lining tunnels; by the tunnel railway Number of Lines points, single line tunnels, lane tunnels and multi-line tunnels. Extend the length of the tunnel is less than 500 meters, called short tunnel; extend between 500-3000 meters long tunnel called; extend between 3000-10000 meters long tunnel called; and more than 10,000 meters of extension , called the Long Tunnel. 1900 years ago, China has artificial tunnel through a mountain. The history of China's first artificial mountain tunnel: praise ramps Shimen. Shimen ramps located in the ancient southern end of Hanzhong pao pao Taniguchi seven plate Heights, 16.3 meters long tunnel, 4.2 meters wide and 3.45 meters high, South Side, 3.75 m high north exit. Two cars in the cave in parallel. Shimen dug in the first century AD, Emperor Ming levels began six years (AD 63 years), to nine years (AD 66 years) completed in April, dating back more than 1900 years of history, is the world's first artificial tunnel through a mountain. China built a railway tunnel Independent: Badaling Beijing-Zhangjiakou railway tunnel. It is China's outstanding engineers Represented Duzao personally planning, people rely on their own strength to build China's first railway tunnel. This single track uphill tunnel length of 1091 meters, just a 18-month period. China's first railway tunnel: Xi'an-Ankang Railway Qinling tunnel. September 6, 1999 through the tunnel up to 18.46 kilometers, ranking the first time the world's mountain tunnel 6, the first two in Asia. "The world's first high tunnel": Fenghuoshan railway tunnel. The world's longest plateau permafrost tunnel: the Qinghai-Tibet Railway Kunlun Mountain Tunnel. A total length of 1686 meters of Kunlun Mountain Tunnel is located in the plateau permafrost zone, complex geological structure, harsh natural conditions. Construction began in September 2001, through September 2002. China's first cross-river tunnel twin bunk: Shanghai Fuxing Road Tunnel. It is west of East Fuxing Road in Puxi, KPS Road, east Pudong Zhangyang, Laoshan Road, a total length of 2785 meters, a total of two six-lane, become connected Pudong and Puxi's also a "golden channel." China's longest railway tunnel: Lan-Xin Railway Wushaoling tunnel, 20.05 km long. China's longest highway tunnel: Zhashui Xi'an Qinling Nanshan tunnel segment, length of 18.4 kilometers. China's longest highway tunnel: Beijing, Fuzhou highway US forest mushroom tunnel, located minqing Youxi County, Fujian Province and the junction of the canyon area, total length of 11.2 km. Jiangsu large waterproof plugging Engineering Co., Ltd. specializes in waterproof plugging, plugging impermeability with water, plugging, plugging the tunnel, basement plugging, cable channel plugging, plugging air defense, caisson plugging, plugging joints drain, railway tunnel plugging, plugging waterproof plugging air defense caves, railway tunnels, underground air raid shelters, a variety of oil pools, pool, storage rooms, pump trench, cable tunnels, elevator shafts, waterproof plugging various channels. Reservoirs, water towers, electric drills, dams, culverts, construction joints, cracks off, cable trenches, deep well pump, air defense caves, underground parking garage, tunnel, put a lot of pool water leakage and coal projects, the use of domestic independence, innovation and technology, grouting seepage, plugging reinforcement. Working with Water, anti-pressure sealing patented formula with water operations, anti-pressure sealing. Quoted from foreign high-tech waterproof plugging technology, using imported polymer waterproof materials, will be equipped with back pressure against the mixed slurry grouting, water expansion accelerating, the elastic material used in tunnels, basements, air defense, subway, pool, tank, Thermal well chamber and mouth of a long-term settlement joint military trenches impervious waterproof plugging. Construction had been plugging the crack mouth, and later settling or dislocation cracks also no leakage. Polymer grouting underground waterproof plugging new technology: Grouting for underground civil air defense, hangars, pumping stations, pools, dams tunnel, rock foundation, to the cable channel and other projects water shut, trapping, anti-infiltration, which is based on micro-organisms a variety of chemical raw materials chemical based agent formulated into A, B two-fluid, with a particular high-pressure equipment, seepage into equal parts to fill the full penetration of construction: 1, highway crossing the river, the railway tunnel settlement construction, expansion joints, cracks in the bottom leaking water waterproof plugging construction. 2, the underground base construction, underground engineering, civil air defense projects, such as sewage treatment pond water leakage plugging construction of concrete structures. 3, basements, underground garages, underground passages, heat pipes, and other types of underground seepage pit plugging construction. 4, pool, cable channel pit, mine access, elevator shafts, foundation pit construction joints plugging leakage of water with water-construction. 5, concrete structure, cooling tower circulating cold water channels, pipes, sewage treatment pond seepage water plugging construction projects. 6, culverts, caisson, pump house, dam, bridge, roof, tunnel, take control plugging leakage of water drainage works construction. 7, hydraulic reservoir dam grouting, plugging cracks in the tunnel, seepage, dam seepage reinforced concrete cracks. New adults willing plugging years rich experience in construction, first-class technology, first-class management, first-class service for various owners of service and dedication to provide the most satisfaction, the best, the most worry the benefits of products for domestic and international customers. Cracks in the leak, in more than 20 years is no longer leaking, the company provides specialty polymer materials and construction technology consulting services. Bridge and culvert plugging joints
