Conventional Pipe Jacking Systems

Conventional Pipe Jacking Systems
Akkerman’s manned TBMs and Excavator Shields, also known as our conventional line of equipment, are the epitome of pipejacking power, control and accuracy in an array of soil conditions. TBMs are suitable where manned entry is permissible. Akkerman TBMs can be used with any jacking pipe up to 14-feet (4.3 m) in diameter and a multitude of drive lengths. Designed for unequaled ease of set-up, the Akkerman system can typically be ready to launch in one day. Excavator Shields remove obstacles at the face of the bore with a backhoe-type excavator. Excavator Shields are appropriate for 96-168-inch (2,438-4,267 mm) OD traditional pipe jacking, liner plate and ring-beam and lagging tunnel buidling projects.

5000 Series I & II Pipe Jacking System
The 5000 Pump Unit is part of a complete, all-in-one pipejacking system containing TBM, hydraulic power unit, skid base sections and a thrust yoke. This versatile system easily adapts to any jacking pipe in any pipe joint length with an appropriately sized TBM and yoke.

Excavator Shield
Excavator Shields differ from the TBM in that they do not have a cutter head or rotating drum, rather they excavate spoils with a backhoe-type excavator. The excavator and control console easily transfer between different shield sizes. The EX 50 assists in the removal of obstacles and spoils at the face of the bore between the sand shelves.

The P600 is a remote pendant controlled, electric power pack to be used with TBM and jacking frame arrangements. The P600 features a 600-gallon (2270 L) hydraulic reservoir with three interchangeable pump/motor modules which are manufactured in job specific low and high pressure configurations.

The battery powered 524 and 1548 haul systems, comprised of a haul unit, track and dirt bucket, transports spoils deposited into the dirt bucket from the TBM conveyor. Haul unit tracks are standard sized in 8-foot (2.4 m) sections and bolt together with ease.

Intermediate Jacking Station (IJS)
To maximize drive length capability, the IJS bears the load by distributing thrust effectively and economically—even in challenging ground conditions. IJSs are manufactured in numerous designs to suit project, size, joint of the pipe, budget, and length of drive. Oil is distributed to the IJS through a set of lines connected to the pump unit.

The electric EH2250 Bentonite Pump provides lubricant to the outside of the pipe, thus reducing friction between the pipe and ground and decreasing the pipejacking thrust. The dual, 250-gallon (946 L) tanks continuously mix and pump bentonite solution with individual propellers at a high volume psi.
