Slurry Pipe Jacking Machine construction is the underground pipeline construction which was developed after shield construction.
This does not require the surface excavation, and can cross roads, railways, rivers, ground buildings, underground structures and various kinds of underground pipelines.
With the help of the thrust of main Jacking unit or main jacking cylinders and intermediate jacking station between the pipes or other thrust pushing the product pipe and heading machine (through the soil) from launch shaft to the receiving shaft and lift up. The process consists of embedding the pipes between the two shafts, In order to realize the non-excavated laying underground pipes. Avoid disruption or any impact of the city buildings and road traffic congestion during construction.
In the stability of soil and environmental protection highlights its advantages. It is very important for cities with heavy traffic, densely populated, with many terrestrial buildings and complex underground pipelines. It creates a clean, comfortable and beautiful environment for the city.
Pipe Jacking Machine is also widely used in underground water pipe, oil pipe, natural gas, for trenchless underground pipe laying projects, e.g. sewage, water supply, discharging projects, cables, tunnel, various communication cable laying pipeline trenchless, this technology doesn't need surface excavation, the pipes are pushed underground into the soil from launch shaft, the pipeline can be curved, and machine can overcome some underground obstacles.
Slurry Pipe Jacking Machine construction is a trenchless (non-excavation) construction, it is a non-excavation or less excavation tunnel construction technology. Pipe jacking construction work is executed inside a pit/well by means of jacking equipment which produce jacking force, and overcome the friction between the pipes and the surrounding soil
Jacking the product pipes into the soil at the design slope while simultaneously excavating soils, after a section of pipe is jacked into the soil, the second section of the pipe continues to, the principle is by means of the thrust of the main jacking cylinder or jacking station, intermediate jacking station, and other thrust pushing the product pipe or heading machine (through the soil ) from working well (launch shaft) to the receiving well/shaft and then lift up. Thus, the pipes are embedded between the two shafts
Applicable to a wide range of soil, soft soil, clay, sand, hard soil, backfill soil.
with strong crushing ability, crushing large particle, independent water injection, grouting system, the jacking speed is fast, the fastest jacking speed can reach 200mm per minute
High precision construction, the up and down, left and right deviation adjustment angle can reach 5.5 degrees.
The use of ground centralized control system, safe, intuitive and convenient.

The advantages of our equipment
1.The shell thickness is not less than 25mm so as to avoid any deformation. It is made as a whole part, not pieced together.
2. Power Box:
2.1 The main axle material is 42CrMo and its gear never breaks.
2.2 Good sealing ensures that mud water will not enter the power box.
2.3 Use of ultrasonic flaw detection ensure no occurrence of cracks and achieve triple flaw detection.
2.4 It's a complex processing from rough finish, forging, heat treatment, flaw detection to fine finishing and chroming.
3. PLC electronic control system
3.1 Humanized design with USB interface under control desk (console) for charging
3.2 PLC program is programmed with motor protection and 5-second delay for fast stop under both clockwise and counterclockwise motor running so that the gear will not be broken for sake of gear protection.
3.3 PLC intelligent control can take a three-day record of operator’s deviation correction in case of unnecessary dispute after any accident.
1. Main drive can be driven by a hydraulic motor, with high torque, high reliability, power and technical parameters are based on Herrenknecht and MTS.
