Cement pipe jacking machine, twin pipe jacking, hydraulic jacking machine 

 Cement pipe jacking machine below the 2000mm-diameter cement pipe Trenchless laying works. Cement pipes hydraulic jacking machine is a domestic small and medium-diameter cement pipe non-excavation of the most widely used in the construction of a top of the nozzle diameter of 0.8 m -3 m to manually dig the soil Piecewise jacking. Cement pipe the output force of hydraulic jacking machine, light weight, long-distance operation, suitable for all kinds of soil, in a layer of quicksand, the complex geology of the gravel layer, sand layer, weathered rock can be successfully laid. 

 Cement pipes and pipe jacking technology parameters: 

 Cement pipe jacking machine diagram of technical parameters: the hydraulic jacking machine is divided into 300T / 1 and 500T / 2, motor power of 11kw and 15kw respectively, the maximum working pressure 31.5mpa host external dimensions of 1.5 × 0.5 × 0.5m, 300T / 1 single top process 1.1m/10min, laying length is 40-60m, 500T / 2 word top carried the process 8m/10min laying length for 50-70m. 

 Cement pipe jacking machine to use: 
 Ministries of a hydraulic jacking machine must be checked prior to use is normal, make sure all hose connections and reliable. 
 2, cement pipe jacking machine should be in strict compliance with the provisions of the main parameters, to avoid overload, or to reach the trip, or suppressed, or when lifting height or lifting tonnage exceeding the prescribed fuel tank at the top of a serious leak oil. 
 3, such as the need to first pump the oil is less than the working oil pump (32 # hydraulic oil) to work. 
 4, the electric pump, please refer to the electric pump manual. 
 , Heavy center of gravity to choose a moderate, reasonable choice of the focal point of the power jack, the underside of pad level, taking into account the soft and hard conditions on the ground, whether or not to pad of tough wood, place is stable, so as not to load subsidence or tilt. 
 6, after the electric jack into the top heavy weights should be timely and supports to support heavy objects securely, to prohibit electric jack used as the support.
