Things To Know About Direct Push Drilling

By Jerry Wright


Direct drilling or technology, often shortened as DPT, is a modality that uses the rigid weight of the rig intertwined with hydraulic hammers, with the core intent to advance tooling as well as instrumentation particularly through the soil subsurface. As opposed to rotary, drill cuttings do not get removed from the hole. Notably, the depth and also speed of penetration largely depends on the type of the soil, the precise weight as well as power of the rig, and also the size of the used sampler. Critically examining these and other crucial details regarding direct push drilling is thus vital.

These technological systems under discussion can be employed in performing water, vapor and subsurface surveys. In this regard, it is important to remember that they have the capability to obtain soil and groundwater samples, as well as installing pre-packed and standard assessing wells. In addition, these drills can also drill and set vapor points, inclinometers as well as piezometers. Also, it supports the injection of a wide range of remediation compounds.

Direct push pulling methods generally provide a viable option or alternative especially to traditional rotary modalities for investigation of not only unconsolidated formations as well as soils. As compared to other rotary drilling techniques that essentially use the removal of cuttings as well as rotation in a bid to advance the equipment or tools deep into the soil or subsurface, these machines usually advance logging tools as well as sampling using vehicle weight and also percussion hammers.

Firstly, this modality has very small footprints unlike other forms. Thus, direct push is very ideal especially for smaller sites. This is mainly because it requires very minimal space particularly for operation, alongside the fact that it has the ability to drill smaller holes compared to other drilling options that are available today.

First and foremost, this methodology ideally has very minimal or rather small footprints. In this vein, it is very ideal especially for slightly smaller sites, and this is based on the reason that it generally needs lesser volumes of space in order to undertake its operations.

Another notable advantage is that this type of water and soil sample collection is that it offers groundwater profiling that is precise. This is because it collects samples by cutting through layers of ground water which aids in measuring the extent of contamination hence gives better and more accurate results than the traditional method.

It is also important to concisely look into the various machines that help to undertake this process or technique. The machines and tools are usually specially designed to interrogate unconsolidated formations. Traditionally, the models of machines used in this technique were mounted on conventional pickup vans and trucks. In the modern society, most of the machines used are usually track mounted systems.

Direct push machines ideally advance equipment and tools in the soil subsurface using things like percussion hammers, hydraulics and vehicle weights. Nevertheless, many of the larger machines used in this technology can also be equipped with coring tools and hollow stem augers. Conclusively, the technology has been designed to enhance efficiency, making direct drilling a prudent move.
