Our Company Realtop is specialzied in making construction machineries, Pipe Jacking System is one of our mature products, which has covered singopare markets:

1. System Description

This slurry balance type Pipe Jacking Machine (TBM) 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.

2. 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.
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.
