What Is a Drilling Bucket?

Drilling buckets are the rotary drilling tools that are used to drill non-cohesive and cohesive soil below the level of groundwater. These buckets are capable to rip and break hard soil to rocks of medium hardness. The construction of these buckets is heavy duty and they are provided with a drive hub to attach suitably to foundation drilling tools as well as foundation drilling rigs of all types. The design of these buckets allows you to use them with the rigs fitted with automatic as well as manually operated opening mechanism.

Features of drilling buckets

  • The heavy duty construction of drilling buckets is also provided with reamer bars
  • They are also fitted with a drive hub known as Kelly Box to match suitably with any drilling tool
  • They are available with 7 options for digging various types of surfaces through single to various combinations of teeth
  • They include manual and automatic opening mechanisms to be used as per the requirement of foundation drilling rigs
  • Base options of drilling buckets include valve and swivel style
  • Different types of drilling buckets can be used for different types of surfaces depending on their hardness levels

Use of drilling buckets with foundation drilling rigs

Foundation drilling rigs are the machines used for creating hole in the sub-surface of the earth. The massive structure of these rigs can contain drilling buckets to drill oil wells, water wells, wells to extract natural gas as well as smaller holes by using the manually operated smaller drilling augers. These drilling rigs can also be used for collecting sample of mineral deposits on the sub-surface as well as testing physical properties of the soil, rock and underground water. They can also be used for installing fabrication tools on sub-surface like underground instrumentation and utilities like wells or tunnels. Drilling buckets can also be used with mobile drilling rigs mounted on tracks, trailers or trucks along with permanent structure on land or offshore platforms.

Use of drilling buckets as rotary drilling tools

Drilling buckets are a kind of rotary drilling tools the rotation of which can be controlled with a hydraulic or mechanical Kelly attached to them. The drilling rigs of this type usually use round locking type or square friction type Kelly with 3-4 telescopic sections extendable up to more than 100 feet. These drilling buckets can be used to drill holes of 10 to 60 inch diameter with the help of the teeth or cutting blades mounted on hinged bottom of their cylindrical structure. They bore a hole by cutting the sub-surface and lifting the sediments repeatedly.

Use of drilling buckets as foundation drilling tools

The drilling buckets are used as foundation drilling tools as the cutting teeth on the bottom of rotating buckets cut the soil to fill in them. When the bucket is full the flap hinged at its bottom will close to keep the soil in it. Then it will be raised by the cables attached to it to take out the soil. The hinged bottom of the bucket will be opened to dump the soil into a pile after taking it out of the hole. Before reinserting the drilling bucket into the hole its bottom is closed. This process is repeated again and again until you reach up to desired depth.

But while using drilling buckets with foundation drilling rigs, the rigs must be placed in such a way so that it should be 8-10 feet above the surface to be drilled or there must be 8-10 feet groundwater from the existing level of the rig. In order to keep the borehole open during the process of its drilling biodegradable drilling fluids like guar gum or other synthetic polymers or water should be used as required.  

You will be able to produce an oversized borehole by using drilling bucket with side cutting teeth in combination with drilling fluid. It will also help the bucket to remove the soil cut within the borehole. In this way you will create a borehole that cannot be covered with drilling fluid or annulus so that solid suspended items can develop to lower the yield of the well.

Thus, drilling buckets can be used as rotary drilling tools for drilling boreholes with the help of foundation drilling rigs.
