Mud water(Slurry Boring) balance pipe jacking machine

 

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
