Product Description
Helical piers, also known as anchors, piles or screw piles, are
deep foundation solutions used to secure new or repair existing
foundations,a modern improvement to traditional cement footings.
Each pier consists of an engineered steel post with screw-like
helices. Helical pile is extendable base equipment which is made up
of helical engineered metallic plates that are attached to a
central steel shaft using a round or rectangular cross-section. The
steel plate thickness, diameter, number, and helices operate are
determined through the restricted or supported arrangement's
minimal design life, the ecological rust, and geotechnical
parameters, along with the design fill demands.
The screw piles are provided in modular sections approximately 2m
long. The lead section normally has three galvanized steel helices
of increasing size welded to the shaft. If further depth is
required, 2m follower sections are provided. Galvanized steel pile
caps are also available.
Helical Piers--Description:
The original helical pier was designed as a wooden shaft with an
iron helix for use in lighthouse foundations.
Today, helical piers are one of the two most common types of
structural piering devices for residential foundation applications
in use today. Helical piers are an excellent choice for foundation
repair and stabilization when light
structural loads, unstable rock foundations or very deep load
bearing stratums are present.

Installation
Screw piles are wound into the ground much like a screw into wood.
Screw piles are installed using various earthmoving equipment
fitted with rotary hydraulic attachments. Machinery varies from
skid-steer loaders to 5 tonne through 80 tonne excavators. Rotary
hydraulic powerheads with torque capacities ranging from 5,000 Nm
to 500,000 Nm are custom fitted using various boom configurations.
Special drive attachments connect the screw pile to the machine.
Correct installation techniques are paramount to meet engineered
design load and settlement outcomes. Incorrect techniques are
likely to result in poor overall pile performance.

The first piece of the helical pile is called the lead; this is the
piece that is first rotated into the ground. The lead has multiple
helical blades, also referred to as helical bearing plates, that
can vary in size, shape, and number. After the lead follows any
number of extensions, depending on the required torque or depth.
These are simply shafts that are bolted and pinned to the lead and
to each other at their ends. The top of the pile is the
incorporated into the foundation system via a bracket or other
connection method.
Helical Piles are used worldwide to secure residential and
commercial buildings, tower foundations, heavy equipment
foundations, and many other deep foundation system applications.
The shaft can come in either a circular or a square cross section
shape and is typically hollow.

Helical anchor system may be used to reestablish new foundations or
restore present ones. Helical foundation anchors are used for
lighthouses, roads, railroads, telecommunication, and in a lot of
different businesses that need rapid installation or structure near
to present constructions. Evidence, maintaining structures, other
common places make use of because they are appropriate for
compression in addition to tensile loads.


What are Helical Anchors?
A helical anchor is a deep foundation solution which is used in
situations when standard solutions cannot be applied to your
foundation project. Situations where a foundation may be exposed to
moisture for a longer period of time or where the soil conditions
are not normal for use, in such a situation a deep foundation
solution like a Helical anchor is required
Helical piers, also known as helical anchors, piles or screw piles,
are deep foundation solutions used to secure new or repair existing
foundations. Due to their design and ease to install, they are most
commonly used whenever soil conditions prevent standard foundation
solutions. Instead of requiring large excavation work, they thread
into the ground. Helical piers are round or square, tubular or bar
steel shafts with round helix plates welded to them.



1. Structural advantages
The spiral ground pile is driven underground in a revolving way, so
the soil is not easy to loosen, and the soil conditions can be well
used. According to the blade structure of the screw ground pile, it
has good tensile pull-out force and insertion grip.
2. Simple and efficient
As a new type of foundation technology, spiral ground pile has many
outstanding advantages, such as convenient construction, short
period, little impact from the construction environment, no damage
to the local environment, easy migration and recycling.
3. Low cost
Compared with formwork erection, rebar binding and pouring of
concrete. Embedded anchor bars, curing, formwork removal,
foundation soil backfilling and other procedures, the spiral ground
pile only needs to be positioned and driven, and the material and
labor costs can be saved.
4. All weather construction
It has little impact on the environment and can be constructed
under most climatic conditions, such as rain, snow, freezing and
other weather.


What are the benefits of Helical Anchors?
There are various benefits of using a helical anchor. Some of them
are as follows:
It is easy to install and remove
It can be installed easily in any weather condition
It reduces carbon footprints
It has minimum vibration
It reduces foundation costs
It does not require excess soil
The installation process is very clean and tidy as there are no
spoils left after installation
What would be the cost of Helical Anchors?
There are various factors involved while deciding the cost of
helical anchors. Those factors are:
Location
Type of work
Condition of foundation
Depth of pile installation
Photovoltaic screw ground pile can reduce the cost of the
foundation of the support system, shorten the installation time,
and reduce the environmental impact of the ground photovoltaic
support system. As a quick and cost-effective solution, it is
applicable to all major solar photovoltaic, wind energy and
construction industries. Its high load performance, stability,
settlement resistance and pull-out resistance are the reasons for
its rapid development.

How To Install Helical Anchors?
Helical anchors are installed before pouring the foundation or the
soil foundation has been damaged
Helical anchors are screwed into the soil and depending upon the
location they are attached to the pre-existing foundation with
brackets or screws. After the helical anchors are installed the
foundation is safe and is ready to combat any future damage due to
compression and tension.
How many Helical Anchors are required ?
The number of helical anchors that you require depends upon the
following factors:
Recommended distance between the piles
The type of structure
What is the purpose of Helical Anchors
The main purpose of a helical anchor is to transfer the structural
load to the soil. There are various other applications also like
tension, compression, and lateral load where helical anchors are
used.
Packaging & Shipping




How to use Helical Anchors?
Drive the helical anchors into the soil up to the predetermined
load capacity.
Space the helical anchors at predetermined intervals to share the
weight of the structure.
For foundation repair works, attach the brackets to the base of the
wall so that the weight is transferred to the anchor.
Install to a height below the ground level where they meet the
required torque.
