Dordach Series Combined Pipe Jacking Machines (DN1000-DN3500)

Scope of application

They are suitable for all kinds of geology and apply the patented technology to deal with complicated geology. Especially suitable for soil, sand, dense soil, mixed weathered rock, and can also break up sandstone, rock, and multiple obstacles, etc.

Applicable material of pipes

Suitable for a wide range of pipes such as precast cement pipes, steel pipes, ductile iron pipes, fiberglass reinforced mortar pipes and clay pipes.

Product introduction

1. The patented cutter technology is good at dealing with complex geological conditions. The response to changes in strength is superior to that of similar products;

2. Installation of additional backwashing water intake and discharge system can avoid blocking of the slurry discharge pipe, which greatly improves the slurry discharge capacity;

3. High customized service realizes highly integrated auxiliary parts, strong relevance to the geology, better passage capacity, strong reliability;

4. The secondary crushing chamber design, through the twisted disk and internal welding, allows repeated multiple crushing for waste materials in the chamber;

5. The disturbance to the soil is small, and there is basically no harm to the surrounding environment;

6. With precise correction, the jacking error can be controlled at ±0-50mm;

7. The slurry treatment is more environmentally friendly and efficient. The downhole integrated slurry treatment or ground slurry separation integrated treatment system is optional; 8. Various models of DN1000-DN3500mm can be customized.
