DIRECT PUSH Meaning and
Definition
-
Direct push is a methodological approach used in geotechnical investigations and environmental site assessments to collect soil, water, and vapor samples from the subsurface. It involves the use of specialized equipment to directly push or advance sampling tools, such as rods or probes, into the ground without the need for drilling or excavation.
The technique typically employs a direct push rig consisting of a hydraulic ram or percussion hammer attached to a truck-mounted, track-mounted, or trailer-mounted platform. The hammer delivers a downward force to advance the sampling tool into the subsurface materials. This process pushes the sampler into the subsurface soil, allowing samples to be extracted at various depths. The sampler can be hollow, allowing for the collection of soil cores, or it can include sampling ports for the collection of groundwater or vapor samples.
Direct push is advantageous for several reasons. Firstly, it is a relatively quick and cost-effective method compared to traditional drilling techniques. It produces minimal disturbance to the surrounding soil, reducing the chances of cross-contamination and preserving the integrity of the samples. Additionally, direct push rigs can be easily mobilized to various locations, making them suitable for on-site investigations or remote areas.
Direct push is commonly employed in environmental assessments to evaluate soil and groundwater quality, identify potential contamination, monitor groundwater levels, or assess subsoil characteristics such as permeability. It is also utilized in geotechnical investigations for soil classification, compaction testing, and determining soil strength parameters.

Etymology of DIRECT PUSH
The etymology of the term "direct push" can be understood by analyzing the roots of each word separately:
1. Direct: The word "direct" comes from the Latin word "directus", which is the past participle of the verb "dirigere", meaning "to guide" or "to align". It entered English in the late 14th century and originally referred to something that goes "right to a target or goal".
2. Push: The word "push" originated from Middle English in the early 14th century. It evolved from the Old English word "puscan", which means "to thrust" or "to exert force". The roots can be traced back to the Proto-Germanic word "puskanan", related to Latin "pulsare" meaning "to beat" and Sanskrit "pushti" meaning "he pusht yonder".
