XCMG XDN400H, the full hydraulic pipe jacking equipment of minimum diameter in China, went abroad to support East Africa and Tanzania, helping local residents get clean and safe drinking water.

The construction site, Dar es Salaam, is located in the east of the Indian Ocean coast of Tanzania, with a humid and hot climate, abundant rainfall and surface water. After the completion of the project, 85% of the rural population and 95% of the urban residents will have access to clean and safe drinking water.

The construction couldn’t be pushed forward at the beginning due to the complex geological conditions. The project department investigated the products in local market, and learned that XCMG has a small-diameter pipe jacking machine, and there are many successful cases, therefore the department decided to make the purchase.

The construction site includes 500m of road, which cannot be dig. The underground layers include fine sand, coarse sand, silt, laterite, clay, hard clay, weathered rock, backfill layer and other strata, which puts forward extremely high requirements for the overall performance of the pipe jacking machine equipment.

● XCMG XDN400H full hydraulic pipe jacking machine applies the graded reverse jacking technology, and only requires ∅ 2590mm for the diameter of the starting well, reducing customer costs;

● The hydraulic motor and reducer are applied with integral mechanical seal, which has good waterproof and moisture-proof performance, especially suitable for construction in regions with abundant rainfall;

● Double pump confluence, fast empty travel speed and short construction waiting time;

● The cutter head speed and jacking speed are adjustable, and the formation adaptability is strong.

In order to ensure the smooth progress of the project, XCMG dispatched professionals to cooperate with the project department and continuously optimize the process. XCMG pipe jacking machine jacked in inch by inch, and the construction of nearly 500 meters was completed at one go.

Manager Ding of the project department praised, ‘This tough project has a tight deadline. We chose XCMG equipment due to our high trust and recognition of XCMG brand. XCMG's pragmatic products and wonderful services have won the trust of the people of East Africa.’

At present, XDN400H pipe jacking machine has completed all the expected tasks, and the construction period is 4 months ahead of the original plan.
