Hydraulic jacking machine (communication jacking machine, underground pipe jacking machine) Description: hydraulic jacking machine factory over the years through continuous improvement from the fourth generation of research products. 2005 to declare the patent, underground pipe jacking machine main structure consists of four major components, the main parts: the main by two double-acting hydraulic cylinder components. Pump station: with a diesel pump stations, active force by electric starter, electric field work hard to solve the phenomenon. Support plate: the role of fixed plant and support Pit. Mandrel and pull head: the role of top and back drag reaming. Reaming diameter ≤φ600mm, construction distance ≤70 meters. Simple hydraulic jacking machine operation, long life, easy maintenance, small and medium trenchless construction unit of essential tools. Hydraulic jacking machine instructions an excavation pit work: length 3.4 m, width 2.2-2.5 m. Whether the underground pipe network and other circumstances determined by the user, the general recommendations in the original soil. 2, depending on the thickness of the top diameter, generally deepened some large-caliber, 400mm diameter can be about 2 meters below the surface of a 2.5 m. Second, after the work of the pit will host the next alignment (with visual) l, first determine the location of the front and rear bumpers good, rotate the adjustment screw, a little tight top edge. 2, find the level of the upper end of the plunger with the level of foot alignment, when the bubble in the middle of the foot for the best. 3, the top line of the pre-determined, first established a good benchmark across the ideal predetermined position with a pre-fall line visual reach three rams and benchmarking. 4. Repeat the above work, according to the inspection machine Wan asked correct or not, if there is no difference can withstand the baffle screw rotating bar. Third, after the above work correctly, start the hydraulic station, starting the job, the first four trees should always measure the pre-ejector top 迸 universal, if not normal and should be corrected. Fourth, after pre-drill the top to exit, you can remove the head, dress slider (cone) and the laying of the pipeline and fixed slider is secured, you can be pulled into the anti-pipeline holes.
