PE pipe jacking Products jacking is a good engineering construction is not easy, but also a less-known works. 1. is a trenchless construction method, which is not less excavation excavation or buried pipeline construction techniques. Trenchless engineering technology to solve the pipeline laying construction of urban buildings destroyed and road traffic congestion and other problems, highlighting its advantages in terms of stabilizing the soil and environmental protection. This heavy traffic, population density, number of ground-level structures, complex urban underground pipeline is very important, it will be for the city to create a clean, comfortable and beautiful environment. Trenchless technology is a term frequently used in recent years began, which involves the use of less excavation, that work well and receiving well to be excavated, and no excavation, that pipeline does not trenchless technology for underground pipeline laying or replacement, the top tube diameter DN800-4500. By working well within the top-buried pipe to be laid, a working tube wells can walk through 1,500 meters above the ground, and also curves through, in order to circumvent some of the underground pipeline or obstructions. 2, its technical point is to correct deviations in the underground pipe extends. Trenchless especially suitable for medium to large diameter laying. Economic, efficient, environmental protection integrated functions. The advantage of this technique is: do not cut the ground; no demolition, no damage to the building ground; do not affect traffic; do not destroy the environment; construction from climate and environmental impacts; does not affect stepped pipeline deformation; saving, efficient, security, and lower total cost. The technology in our country economically developed coastal regions are widely used in urban underground to the sewer, trenchless laying of natural gas pipelines, telecommunications cables and other pipelines. It can cross roads, railways, bridges, mountains, rivers, straits and ground any building. Using the technology of construction, can save a lot of land acquisition costs, reduce environmental pollution and road congestion, with significant economic and social benefits. 3. Development and works: An underground pipeline construction method is the second pipe jacking shield construction and developed, it does not require excavation of the surface layer, and the ability to cross roads, railways, rivers, ground buildings, underground structures and a variety of underground pipelines. By means of pipe jacking pipe between the fuel tank and the main thrust of the top relay between the like, the tool tube or boring machine through the soil from the work has been pushed to the receiving borehole wells lifted. At the same time, but also put a tube or pipe tools immediately after boring machine buried between the two wells, in order to achieve trenchless laying of underground pipes. 4, the classification currently in pipe jacking the most popular, there are three equilibrium theory: pressure balance, muddy water, earth pressure balance and equilibrium theory. Pipe jacking most prominent feature is the adaptability of the problem. For different geological conditions, construction conditions and design requirements, selection of pipe jacking manner to adapt, how to properly select jacking machine and auxiliary equipment for pipe jacking it will be very critical. 5. mold top part of the system, also known as Division tube top tube is hollow thimble. The advantage of using PE pipe jacking flared adhesive connection, easy installation. Good insulation properties. Excellent impact resistance, Buried in the ground can be used. Acid and alkali resistance, aging resistance, can be used in harsh environments. Ring stiffness, high strength.
