Mud water(Slurry Boring) balance pipe jacking machine can be used in the condition of underground water pressure high and soil behaviour variation range big, common pipe diameter <φ1350. Its thrust small and perturb small to about soil body ,easily control ground surface subside and may come true to continous unearthed work, jacking speed fast.
Technical Characteristic:
- Fit in soft soil, clay ,sandy soil ,gravel soil, hard soil ,etc. wide range of soil body.
- Breakage ability strong , breakage particle size big and number more.
- With independence water and slurry injecting system and washing clean device for cutter. In particular, fit for big N value hard soil.
- Jacking speed is very fast, maximum speed 120mm/ per minute.
- 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.
- Adopt ground operation system ,safety ,intuition and convenient.
- Structure firm, use and maintain easy, convenient for dismantling in work tunnel receiving tunnel
