Product Description
NPD series Tunnel Boring Machine construction is the Underground pipeline construction  which developped after   shield construction.   
It does not need require the excavation surface,And it can cross roads, railways, rivers, ground buildings, underground structures and various kinds of underground pipelines, etc.
With the help of the thrust of main cylinder and intermediate jacking station between the pipes and other thrust pushing the tool pipe or heading machine (through the soil )from working well to the receiving well and Lift up.At the same time,embed the pipes between the two wells ,In order to realize the non-excavated laying underground pipes. Avoid destruction 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 will create a clean, comfortable and beautiful environment for the city.

Application Scope:
NPD series Tunnel Boring Machine  is widely used in underground water pipe ,oil pipe ,nature gas ,for trechless underground pipe laying projects, eg. sewage, water supply, discharging projects, cables, tunnel,various communication cable laying pipeline trenchless, This technology doesn't need excavation surface ,it push the pipe to the soil begin with star shaft,and it can curve ,overcome some underground pipeline obstacles.  
Principle
NPD seriesTunnel Boring Machine construction is trenchless (non-excavation)construction ,It is a non-excavation or less excavation of the pipeline embed construction technology.Pipe jacking construction is in the work in the pit by means of jacking equipment which produce jacking force, and overcome the friction between the pipes and the surrounding soil
Jacking the pipes Into the soil at the design slope.and Removed soils ,
After a section of pipe finish jacking into the soil , then the second section of the pipes continue to jack into the soil , The principle is by means of the thrust of the main cylinder    pipeline, intermediate jacking station,and other thrust pushing the tool pipe or heading machine (through the soil )from working well to the receiving well and Lift up. Then , embed the pipes between the two wells
 
Main Features: 
Applicable to a wide range of soil, soft soil, clay, sand, hard soil, backfill soil.
With strong Crushing ability, crushing large particle   
With independent water injection, grouting system;
Jacking speed is fast, the fastest jacking speed can reach 200mm per minute
High precision construction, the upper and lower, 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 tunneling machine is suitable to drill in soft, clay, sandy, gravel soil, hard soil,  and back fill . 
2. It has the advantage of  stronger breaking capacity, larger diameter of broken grain and more numbers. 
3. It has independent water injection and grout injection system.  
4. With rapid push speed, it can get max speed 200mm per min. 
5. With high accuracy of construction, it can rectify a deviation upper, lower, left and right , and get max Deviation Adjustment Angle 5.5°
6. It adopts surface centralized control system, which has  been safer, Intutive and more comfortable. 
 
Advantage
The mini-boring machine pushed forward by the main cylinder,The boring head enters the water stop ring, pass through the soil and reach the receiving wells,The motor provides energy to turn the cutting knife plate,Through cutting knife plate into the soil,Excavated soil, stones, etc. are crushed by rotating cutting knife, then into the slurry tank , it is mixed with the slurry, and finally through the slurry system of the sludge pipe ,transfer to the ground by the pump,In the excavation process, the use of complex muddy water balance device to maintain soil and water balance, 
It Always in an active and passive earth pressure this to eliminate the settlement and uplift of the ground.After the boring machine is completely in the soil.the Cable and slurry pipe is removed. After Hanging the first section of the pipe,it was pushed to the tail of the boring machine, after connecting  ,Excavation stopped, the hydraulic slowly recovered.Another pipe into the well again ,which was after the first section of the pipe ,it connected together and re-jacking,This process is repeated until all the pipes are covered with soil,Complete a permanent underground pipeline.
