Helical piers have other names in the industry such as, helical torque anchors, screw anchors and screw piles. They are a critical element in stabilizing new foundations and building existing foundations for residential and commercial buildings. The use of helical pillars, in particular in Oklahoma, has many advantages, where loose granular soils are present at many locations in the State. See here why piling suppliers always swear by helical piers.
Load Bearing Benefits
Since helical piles are like a screw, they can be driven deep into the ground by hydraulic equipment, to increase the heavy structure load-bearing and the foundation capacity. In Oklahoma, where most soil conditions are at best challenging, helical piles are very well working.
Generally, helical piles benefit general contractors with cost savings options that can be combined to avoid costly and large excavations. They can simply thread into the ground, if loose granular ground make construction difficult to install traditionally.
Fast Installation
In comparison with other pile types, helical piling provides a far faster rate of installation with typical rotational rates from 6 to 10 rpm, which can be time consuming and costly. Although some factors may have a different effect on each site, most anchors are driven about two feet a minute.
In other words, in less than 30 minutes a 50-foot helical pier can be installed. Not only does this incredibly fast approach speed up the building process but it eliminates the need to wait until concrete has been cured. Finally, its ability to carry loads instantly when installed is the major advantage of fast helical piling.
Low Cost of Mobilization
While more conventional piles require special installation systems, smaller devices such as track excavators and mini excavators can quickly install helical piles. Contractors can react quickly, move around the site more efficiently and save on installation costs.
Better Productivity
Depending on the project, on average, a single operator and worker can install between 30 and 40 helical piles a day. In other words, a pile takes just 30 seconds to reach the ground by 1 foot and 5 minutes to reach 10 feet at an installation rate of 6-10 rpm. Substantial increases in productivity and a more economic process of installation is possible are due to the lower direct labor costs.
Work on Ill Weather
Smaller equipment, more maneuverable equipment than other foundations are required for helical piles, and thus the installation process is more tolerant of the weather and the low terrain. Contractors can even install helical piles without significant loss of productivity. The lighter-weight equipment minimizes the environmental impact and cleanup costs.
