pipe jacking machine for clay, pipe jacking machine for sandy clay, drainage, swage, wastewater
System Description
This slurry balance type Pipe Jacking Machine is used for underground trenchless pipelines laying for swage and drainage. It combines multi-disciplinary technologies in one, such as the machinery units, hydraulic system, electric controller (including PLC), Laser system, measuring device, etc. It has various advantages like high efficiency, no effect on the traffics on surface, good for the environment and it can lower the cost of the construction. Due to its application of various new technologies and adaptation to clay soil, sandy soil, and soil mingled with small pebbles or gravels, this machine has satisfied the needs of Mini pipe jacking constructions well in China and Singapore.
Specification
1. Fit in soft soil, clay, sandy soil, gravel soil, hard soil, etc. wide range of soil body.
2. Breakage ability strong, breakage particle size big and number more.
3. With independence water and slurry injecting system and washing clean device for cutter in particular, fit for big N value hard soil.
4. Jacking speed is very fast, theory maximum speed 120mm/per minute.
5. Operation precision high, may correct an error from up and down, left and right. Maximum corrective angle is 2.5, and may jack forward in a long distance.
6. Adopt ground operation system, safety, intuition and convenient.
7. Structure firm, use and maintain easy, convenient for dismantling in work tunnel receiving tunnel.
