Helical Piers Vs Push Piers: What's The Difference?

There is a difference. This category of piers has a dozen names, each of which is very narrow, custom designed, but broadly used to support and improve general funds.

Let's be a bit narrower and determine the differences and applications.

The spiral pier is a square bar or a tube that is screwed (very similar to a post hole spindle). A hydraulic motor rotates the tube, which is screwed into the ground. The direction can be either vertically or at an angle (the degree of the jar) as required by the design. The harder the soil, the higher the load. Its unique feature is that it has the same capacity for compression (vertical load) as for tensioning (masonry).

Built-in capacity with built-in equipment, no building, base or other mass.

Ideal for new construction, light loads, broken bases, ties, stress loads, temporary applications (easily removable) and typically 156 Kips maximum capacity (1 kip = 1000 pounds), although there are some larger capacity resources

with the harbors (so-called resistors)? These are open end pipes that are pushed vertically into the soil as long as they are placed in a soil that has been determined to be strong enough to maintain the load. A hydraulic rod is used for inserting the piers and then fixed to the structure. The weight of the structure creates a resistive resistance, so the name pushes the piers. The capacity is limited to the direct load of the building. This is a one-off capacity, no security factor (FS). The FS has several propulsion piers that share well-designed loads. Full capacity can only be achieved if the reaction load is difficult enough to withstand

The push pier is a powerful pier, though it is very simple. Stable and ideal for heavy loads. It can be installed on a very small area and can support the existing base that can be subjected to a neighboring excavation. Typical maximum capacity of 90 Kips.

Some applications have overlaps, such as nominal and rather severe remediation projects and backing. The push pad or tieback can not be removed because their sections are only for compression. Neither a new construction pier can be, because the reaction mass should be in place. It should not be used in light weight (because of the minimum weight) or with cracked or broken legs.

Helical piers can do most of the remediation work because they produce their own capacity from the weight of the structure and not the "load-releasing load-release load" as the push piers. This is not as good as a supporting pier that supports it because it can not be fished with a finger. Helicopter piers are more expensive, but they go faster. In most cases, the same foot is used.

Both are vibration-free, cost-effective, long-lasting, engineering and building approval approved, with 30 years and over, planning, field testing, and actual on-site use. Properly installed, the error rate is so small that it does not actually exist. Most errors are related to other factors. Every pier can be easily recharged for proper performance

Whether the installer chooses the spiral or push jib, you can be sure of a joyous decision and solution to the problem
