CAPABILITIES

Laney Inc. has both the knowledge and the resources to complete almost any road boring project up to 48". Our specialty is pipelines, and with a large arsenal of boring and support equipment, Laney is capable of getting your project completed on schedule.

Our boring equipment includes: dry bore rigs (both cradle and track), slick bore rigs, pneumatic hammers and horizontal directional drill rigs.

Our support equipment includes: excavators, pipelayers, dozers and winch tractors.

Transportation is critical, and with our fleet of heavy haul trucks and trailers, we're able to mobilize quickly any equipment necessary to complete a job.

TYPES OF BORING

SLICK BORING

Slick Boring is a bore pit launched system that advances a rotating drill stem along the path of a proposed bore, referred to as a pilot hole.

The drill stem continues along the proposed path until the drill stem exits into another pit, called the exit pit.

A reamer or hole opener is attached to the drill stem.

Attached to the rear of the reamer is a swivel and tail cable.

The slick bore machine then rotates the reamer, as fluid is pumped through the drill stem to the reamer, and pulls the reamer back to the bore pit.

Typically the drill stem is 6 feet long.

The boring machine is 16 feet long and the typical bore pit is 8 feet x 20 feet.

GUIDED PILOT BORING

Guided Pilot Boring is a process used in directional drilling and in slick boring.

Guided pilots are done with a steering head connected to the tip of the drill stem and is calibrated with a locator to accurately predict the direction and depth of the drill head.

DRY (AUGER) BORING

Dry (Auger) Boring is a pit launched system that advances a casing as the hole is bored through the ground.

The dry bore machine pushes the casing forward as it rotates an auger inside the casing.

The spoil is removed through the casing by the rotating auger.

The spoil is deposited in the bore pit and then removed.

Typically this operation requires one pit as long as each pipe section to be installed, plus the length of the machine itself.

Typical bore sections are 80 feet in length, but can be reduced to 40 feet in some instances.

As each section is installed, another section is welded to the installed section and the process is repeated over again until the casing reaches the exit pit.

BORE & JACK

A Bore & Jack Bore uses a combination of methods.

A guided pilot is run with a boring machine the length of the bore.

After the pilot is run, the steering head is removed and a reamer the size of the line pipe is installed on the drill stem.

As the drill stem is retracted and the bore is reamed, the line pipe is advanced int the bore a few feet behind the reamer from the opposite side of the crossing.

PIPE RAMMING

Pipe Ramming (Hammering) is a non-steerable system of forming a bore by pneumatically driving an open-ended casing using a percussive driving device from a pit and only displacing the wall thickness of the casing.

The percussive driving device is driven by an air compressor.

The soil will remain in the casing until the bore has been completed and then may be removed by water, jet-cutting or compressed air.
