Up and down pressure on dpt drill rig [PDF]

6 FAQs about [Up and down pressure on dpt drill rig]

A probe is pushed into the ground using hydraulic pressure, hence its name “direct push.” The DPT rods push to the depth desired to be sampled with the sampling unit mounted at the bottom of the string of rods being pushed into the ground. DPT units can range from small cart-carried rigs to very large truck or track-mounted rigs.

Should rigging up/down be guarded?

While complete guarding is not possible at all times during rigging up/down, keep floor openings covered when not in use. Handrails around the rig floor should be put up first and taken down last when rigging up/down the rig floor. Stairs should be placed as soon as possible and taken down as late as possible.

What should be done before rigging up/down a drilling rig?

Pre-job planning should be done to determine the safest and most efficient means to do the job. Once the rig move planning has been carried out, a pre-job meeting with all involved should be held. The following safety tips should be observed when rigging up/down a drilling rig.

What is DPT used for?

It is also used for collection of geochemical, geophysical, and hydrogeological data below ground. DPT was originally developed for agricultural and geotechnical soil evaluation, but its use quickly spread into environmental applications.

How should rig rigging be handled?

Handrails around the rig floor should be put up first and taken down last when rigging up/down the rig floor. Stairs should be placed as soon as possible and taken down as late as possible. Once placed the stairs should be secured against movement. Be aware of the movement of trucks and other equipment around the rig location.

Is DPT a good method for soil and groundwater sampling?

When used with appropriate quality control protocols, the data obtained from DPT can be of very high quality. DPT is a very cost-effective method for conducting soil and groundwater sampling at contaminated sites. 7. Photo by EPA Region 7.
