HELICAL PILE SUPPLIER PHILIPPINES

Alberdo Industries has supplied helical piles for different projects in the Philippines.

Helical piles are pipes with helical plate welded on its body and along its length. It can be used as piling support or foundation to a concrete structure such as in bored piling. Although unlike bored pile that are being driven or hammered, helical piles are being twist to penetrate the ground. It can be achieved due to its unique helical plates.

The pipe and plates are made up of high steel grade to resist the bearing pressure upon driving. The plate is welded on the pipe in a helix manner to facilitate easy penetration on the ground. The helical plate is welded on the bottom portion of the pipe. The capacity of the helical pile can be adjusted by modifying its diameter, thickness, and the number of helixes. 

Helical piles also known as screw piles is a unique foundation technique because it can resist axial, uplift, and shear force. It can be used as structural support, underpins for existing structures, anchoring, and others.

Helical pile was first described by a blind Irish civil engineer Alexander Mitchell in his book in 1830’s. However, long before its publish, screw piles are already popular as pile foundation for lighthouse. 

The design of the helical piles are heavily dependent on the combined structure design load requirement. It is also important to check the geotechnical parameters and corrosion parameters of the site. We also need to identify the minimum design life of the structure to be supported or restrained. 

The most common usage of helical piles is as underpin for existing structure. Because of the restricted area of the site, small dimeter helical piles are best to use.

Helical piles can be used as permanent casing for bored piles

Helical piles are ideal for structures situated in undesirable terrain because they can resist lateral and axial forces.
