Process of HDD Machine

Digging a pilot hole

To begin with, a borehole is drilled along a predetermined path in the ground by the horizontal directional drill. The drilling head is hollow and is pushed through the ground, steered by the driller who uses a transmitter to determine the precise location of the drilling head.

Pre-reaming

The pre-reaming stage involves using the horizontal directional drill to enlarge the pilot borehole. It is completed in stages and ensures that pullback pressure will be lower when the pipe is eventually installed. Completing it in stages also means that the structural integrity of the hole is maintained.

Drilling fluid is also pumped in to remove solids and enlarge the hole. The fluid also helps maintain the structural integrity of the hole.

Pipe pullback

The final stage of pipe installation using a horizontal directional drill is pipe pullback. This is where the drill string is pulled back along the path of entry and the pipe is inserted in its place. Pipe pullback involves calculating the force required when pulling the drill string back as an incorrect force could damage the structure of the hole or product being installed.

HDD Machine Construction Safety Precautions

Various protective facilities and safety devices should be complete and intact, and reliable protective covers or protective railings should be installed on exposed rotating parts.

HDD Machine should be installed firmly and horizontally. The drive wheels should be aligned vertically and parallel horizontally, and the drive shaft and drive wheels should be kept horizontal. Electrical equipment should be installed in a dry, clean and well-ventilated place.

When installing the drilling rig, the tangent point of the front wheel of the derrick crown, the center of the vertical shaft of the drilling rig and the center of the drilling hole should be in a straight line.

When the machine is rotating, it is forbidden to scrub, disassemble and repair the machine parts; it is forbidden to cross the transmission belt, the rotating part or pass objects from above it; it is forbidden to wear gloves to hang the belt or wax; Before drilling, the equipment, safety protection measures and facilities should be inspected and accepted. When reaming, sweeping off cores, sweeping holes, or drilling in karst caves or loose and complex strata, it should be operated by the machine team leader or skilled technicians.

FAQ

Q: How long is your delivery time?

A: The specific time depends on the model and quantity. If the machine is in stock, it usually takes 3-5 days. If it is customized, it will take 15-30 days.

Q: Do you provide samples? Is it free or extra?

A: Yes, we could offer you the sample machine. But it's not free.You need to pay for the sample and the cost of freight.

Q: What is your terms of payment?

A: We accept T/T, Westem Union, Money Gram, Paypal, etc.
Payment<=USD 5000,100% in advance. Paymenb>=USD 5000, 30% T/T in advance, the balance 70% should be paid before delivery..

Q: How does your factory do regarding quality control?

A: Quality is the most important principle. Yugong people always attach great importance to quality controlling from the very beginning to the very end. Our factory has passed ISO and CE certification.

Q: What about warranty and do the engineers available to overseas?

A: One year warranty. During this period, if the machine has some problems, our engineers can go abroad to fix for you.

Q: What is the difference between HDD and HDB?

A: Horizontal Directional Bores use Horizontal Directional Drilling (HDD) technology with the notable difference in HDB being no curvature in the bore. To complete a HDB, a drill rig is set up on one side of the crossing and advances lengths of drill rod through the crossing to create a small borehole (pilot shot).

Q: What are the different types of HDD machines?

A: A horizontal drilling machine is a machine tool which bores holes in a horizontal direction. There are three main types table, planer and floor. The table type is the most common and, as it is the most versatile, it is also known as the universal type.

Q: What is the rule of thumb for horizontal directional drilling?

A: The rule of thumb is that 10 x diameter of the reamed hole should be the depth of cover in OTR ground conditions. Depth of existing services located along the bore path and required clearance. The intended use of the bore – either gravity or pressure mains.

Q: How does HDD drilling work?

A: The first stage consists of directionally drilling a small diameter pilot hole along a designed directional path. The second stage involves enlarging this pilot hole to a diameter suitable for installation of the pipeline. The third stage consists of pulling the pipeline back into the enlarged hole.
