Q235 Steel Galvanized Ground Screw Solar Mounting System Foundation Anchor Pile
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, 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.
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.
Ground screw system is a modern foundation system,using the drilling machine to install which makes it as the most efficient and cost-saving footing solution.
It can be widely applied to different soil conditions.
Ground screw appliation:
Solar system;
Timer-fram construction;
Advertising and traffic systems;
Urban garden and landscape construction;
Flag poles and so on.
Screw anchor advantage:
Save time;
Easily assembled;
Save power;
Save money;
More environmental than Concrete Foundation method
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.
Ground Helical Anchor& Earth Helical Piers--Advantages
. A time-proven, versatile, and technically sound system.
· Lower cost and faster installation than other methods
· Installs quickly with small or handheld equipment.
· Can be installed in limited-access areas or tight access.
· Site cleanliness and minimize damage to landscape.
· Soil load bearing capacity is tested during installation.
· Helical anchors available with single, double and triple helix blades.
Advantages:
(1) The aluminium clamp with a friction welded copper insert clearly marked in blue for making copper conductor connections.
(2)tooth type, small contact resistance, reliable connection
(3)Siamesed parts, will not fall any part during assembly
(4)Hold a large area of arc, the contact surface will be more close which will improve the grip strength between clamps and conductors,to prevent thermal ratcheting under cyclic loads. Interface between aluminium clam body and tap copper shape is protected.
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.
Quality control:
*We have specialized QC testers to check the quality of the products according to different customers'
requirement. Usually, it's random inspection, and we also offer 100% inspection at a reasonable price
if required.
*We have IQC to check the dimensions and surface of the incoming material
*We have PQC to inspect full-course during the manufacturing processing
*We have FQC to inspect all the anodizing/plating and other finishes' products from our supplier and
proceed with the professional quality and appearance inspection before shipping.
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.
