Step-By-Step Procedure for Directional Drilling

Upon arrival of the job site, a survey of the area will determine where the equipment will be staged for the bores and the work shift. All existing utilities will be located prior to drilling to ensure exact depth, size and type of utility.

The Vermeer 24 X 40A directional boring machine will then be set up and aligned where the conduits are to be installed. A small pit directly in front of the drill will be excavated by hand or machine to help assist entry of drill head into ground and also help contain drill fluid.

The locator/foreman will check and calibrate the drill head transmitter and lock it in onto the drill lead stem. The machine operator will then lower the front of the drill to ground elevation to 15 degree or 26 percent angle. The operator from his seat will use his controls to automatically anchor the machine to the ground with its automatic stake down system. A mud recovering vacuum unit will then be put into place at the excavated hole site (800 gal. Vac-tron, trailer-mounted unit) to reclaim all drill fluid. All mud will be contained and reclaimed with the vacuum unit and disposed of accordingly. Bentonite is an environmentally safe and non-toxic additive used in the directional boring process.

A radio check with a locator/foreman and operator will be conducted to ensure positive communication at all times. (Motorola, nine channel, high quality two-way radios are used).

When drilling commences the locator will monitor the direction, angle, head temperature and depth at all times and marking exact depth every 5-10 feet with white marker paint on ground surface.

When a target depth and angle has been reached the locator will notify the operator to turn the drill head to a clocked position ranging from 1 to 12 o'clock on the locator computer screen. (Digi-trak locating system with a hand held box for the locator and a remote view screen for the operator is used.) The locator will then proceed to tell the operator what clock position to set the drill head at, once the position has been reached the operator will push the drill head with high water pressure in front of the head to ensure path opening for the steering of the head. Example: The operator pushes the head at 12 o'clock the drill head will then start to steer itself up and if pushed at 6 o'clock will steer itself down. The same would go for 3 o'clock to the right and 9 o'clock to the left. Always monitoring the change in elevation and angle of the drill head.

Once the drill head has exited on the other side to its predetermined target the drill crew will then disconnect the drill head by unfastening the specially machined locking collars. (Pipe wrenches are not used to install or remove drilling tool). A back reamer will be connected to the lead drill stem with a swivel assembly to ensure pipe to be installed does not rotate.

When an "all clear" is determined the operator will check his drill fluid flow and begin spinning the back reamer and begin to cut a hole back toward the drill stem entry point while simultaneously pulling the pipe in.

As the operator pulls back each 10 foot drill stem, automatically disconnecting and loading them into the rod rack.

When pipe arrives on the other side, pipe-ends will be power washed, pulling caps removed, pipes capped and plugged. Any excess drilling fluid would be vacuumed; any open pits would be back filled with markers for pipe ends.

The equipment would be loaded back on trailers, mud would be disposed of accordingly and end of project would be complete.

Ramming Assistance Before Drilling

Conductor Barrel™ launch tunnels allow the bore to begin without complications from the surrounding soil. We then use GRUNDORAM® to drive steel casings at an angle through difficult soils, then use an auger to remove spoils. Ramming Assistance Before Drilling
Your drill can then begin in a more desirable soil type. In the case of bedrock or layered rock conditions, a down-hole or mud-motor can be guided to the rock through the Conductor Barrel pipe. A launch tunnel will also provide a nearly friction-free leg for product pull-back. Ramming Assistance Before Drilling

Ramming Assistance After Drilling

Long drill runs and adverse soil conditions can cause several problems: your drill rig can cause Hydrolock, drill stems can freeze up and pipes can become immobilized during pullback. Now there is a method to help overcome these conditions. Ask about Pullback Assist with GRUNDORAM pneumatic pipe rammer. Ramming Assistance After Drilling
