NPD1500 SLURRY PIPE JACKING MACHINE PARAMETER Product Description 2600mm Railway Tunnels Pipe Jacking 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: 2600mm Railway Tunnels Pipe Jacking Machine is also 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 2600mm Railway Tunnels Pipe Jacking 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 p
