Product Description

Product Description:
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.

Application Scope: 
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.  

Principle:
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
 
Main Features: 
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.
1.NPD series slurry pipe jacking machine is suitable to drill in soft, clay, sandy, gravel soil, hard soil, and back filling. 
2. It has the advantage of strong breaking capacity. 
3. Equipped with independent water injection and lubrication.  
4. Has rapid jacking speed, reaching 200mm per min minutes. 
5. With high accuracy construction, can rectify a deviation upper, lower, left and right , for a max deviation adjustment angle 5.5°
6. It adopts surface centralized control system, which is reliable, safe, intuitive and more comfortable operation. 

Advantage:
The pipe jacking machine is pushed forward by the main jacking cylinder,The boring head enters the launch ring, excavating the soil until reaching the receiving well, the motor provides sufficient energy to rotate the cutting wheel, through disc cutters or scrappers the soil is excavated. The soil particle is crushed through rotation by disc cutters or scrappers in front of the cutter head, then enters into the slurry tank or mud silo to be discharged through discharge pipe by slurry system , the mud silo or front mud cabinet mix the spoil with water, to smoothly execute the excavation through the the sludge pipe of slurry system, transferred to the ground by the discharge pump. In the excavation process, there is use of complex muddy water balance device to maintain soil and water balanced. After jacking the first product pipe, cables, hoses and slurry pipes are disconnected. Then another pipe is launched into the well again,   connect with the previous then jacked, this process is repeated until all the pipes are launched to complete a permanent underground pipeline.
