Equipment installation and maintenance of public facilities ,8-500 tons crane our construction personnel are subject to regular professional training and education on a variety of high, hard, heavy, insurance lifting installation has extensive work experience. Company at a reasonable price, safe and efficient service, while the spirit of fair competition guidelines to enable enterprises have been expanding, lifting, precision lifting, equipment, shift capacity is growing. The Company undertake the lifting, installation and other projects, according to a variety of devices, components and other objects of the material, the structure, the strongest and weakest point, line, surface and the center of gravity and other details, combined with field environment seriously and carefully analysis only after all work to ensure the correctness of engineering, safety. Gas hydraulic jacking, hydraulic jacking rivers, mountains hydraulic jacking, mountain top tube. Welcome to call us, the price is cheap. A, pit excavation work: length 3.4 m, width 2.2-2.5 m. Provided by the user whether the underground pipe network and other circumstances, the general recommendations in the original soil. 2, according to the thickness of the top diameter, generally deepened some of the large diameter, the diameter of about 400mm below ground two meters in a 2.5 m or so. Second, the host down into the pit after work to find positive (by visual inspection) l, first determine the location of a good front and rear bumpers, rotate the adjustment screw, the top tight little force. 2, to the level of the upper mandrel alignment with the horizontal ruler, when the bubble in the middle of the foot position is the best. 3, the top line of the pre-determined, the first predetermined position on the opposite ideal set a good benchmark, with a line sinkers visual pre-ejector and benchmarking to achieve three points. 4 Repeat the above work, according to inspection machines Wan asked correct or not, if no difference can withstand the baffle screw rotating bar. Third, the above work is correct, start hydraulic station, began operations, the former four ejector should always measure the pre-top Beng universal, if not normal and should be corrected. Fourth, pre-drill the top to exit, you can remove the head, pull the head dress (tapered) and the laying of the pipeline and pull the head fixed firmly fixed, you can pull the tubing into the hole counter. Features a pipe jacking equipment, suitable for soft soil or water-rich soft soil; 2, no cut-and-earth, little impact on the ground; 3, less equipment, the process is simple, short construction period, low cost, fast; 4, for for medium pipes (1.5 ~ 2m) pipeline construction; 5, large diameter, long jacking, correction difficult. Can cross roads, railways, rivers, ground-level structures underground pipeline construction.
