Piezometer Installation
Piezometers can be installed through hollow stem augers, air rotary holes, and rock core holes.
Difference Between Piezometers vs. Monitoring Wells
Monitoring wells and piezometers both consist of open pipes setup in the ground. These wells passively allow water levels to rise and fall inside them. The major different between the two is how far along the pipe water is entered. A monitoring well provides the water to go through most of the length of the pipe, while the piezometers allow it to flow only at the bottom of the pipe. Another major difference between the two involves groups of piezometers having the ability to isolate and interpret water pressures response to depth, differential permeability of strata, and water flow. These responses cannot be detected with the use of a monitoring well because the process of a monitor well includes; different water pressures intercepted at a variety of depths, all within the same instrument, that cannot be divided as independent factors.
Spartan Drilling Construction and Installation Of A Standard Piezometer
Spartan Drilling uses a standard piezometer which is constructed of a .5 ft to 1 ft screen, enough riser to extend above the ground, well cap and vented well point. The length of the piezometer is determined by the depth of the zone being monitored and the diameter is about 1 inch, unless other requirements are needed. Our Spartan Drilling step-by-step installation process involves the following:
1. Drilling a to suggested depth with 6-inches added below-ground length of piezometer and 3-inch diameter
2. Packing sand into the bottom of the added 6-inch hole
3. Insertion of the well-point and pipe into the sand
4. Adding sand around the length of the screen
5. If sand filter is below water table, pour sealing material (bentonite pellets) in the space OR if sand filter is above water table, pour sealing material (bentonite pellets) at least 6-inches above sand filter and wet with water
6. Finalize with pouring grout down remaining space to the ground surface
Spartan Drilling Equipment
The equipment we use for our piezometer installation is the Hollow Stem Auger, Air Rotary Drill, or Rock Core Drill. Each have different uses and purposes:
Hallow Stem Auger: With this drill, we are capable of installing the piezometer while the auger is still in the ground. The hollow stem auger allows the stoppage of all unwanted material by providing a casing of the surround soil.
Air Rotary Drilling: High-flow air is constantly injected through the drill string. This helps clean the bottom of the borehole, allowing for consistent contact between drill and bedrock.
Rock Core Drilling: Drilling through rock mass for installation of piezometer.
Spartan Drilling teams are properly trained to perform a variety of services, especially well installations. We are provided with the most up-to-date equipment to complete any project. Give us a call today and we can help you with your next project!
