Piling Pipe

Piling Pipe

Piling Pipes are frequently utilized in deep foundations to carry loads from the building to deeper, stronger soil layers. Skin friction and point bearing are used to resist the loads. The pipe can be driven in either an open-ended or closed-ended fashion, using points or plates. If plates are used to drive the pipes, they can later be filled with concrete to reinforce the pile.

The Development of Piling Pipe

Since the late 1980s, piling pipe has grown in popularity and application by leaps and bounds. After a series of intensive testing established the effectiveness of Piling pipe in bearing loads, the use of Piling pipe in the civil construction industry exploded.

Now for projects involving huge loads or deep foundations, piling pipe has become the preferred solution. This is due to the load-bearing capacity of the piling pipe, its customizability, and its cost-effectiveness. There are alternatives to piling pipe available, such as concrete or wood, but they are not as simple to use or as economical as piling materials.

Vertically driven piling pipes are used to create a deep foundation for major commercial and industrial buildings. The foundation’s structural weight is transferred to the soil below by piling pipes. The pile designs will vary according to the ground conditions and expected support, allowing the pile systems to be customized to meet any unique requirements. They can support exceptionally enormous loads due to their steel construction, and the correct steel can make them nearly immune to environmental conditions. Pilings are used to support extraordinarily huge or heavy structures if the topsoil is insufficient. Additionally, they are employed when the available land area is insufficient to allow spread footers or foundations. Vertical pilings are driven deep into the ground, where the soil is more compact.

Types of Piling Pipe

While all piling methods utilize driving pipes, varied soil conditions and structural requirements necessitate the use of specific types of piling pipes. Here is a rundown of some of the most prevalent:

- Unplugged Open-Ended

These are totally open-ended pipes. Following installation, the ground level within and outside the pipe should be identical. They largely distribute their burden to the soil via friction.

- Plugged Open-Ended

These have a stopper at the pipe’s bottom end. This results in the dirt inside the pipe being precisely less dense than the soil outside the pipe.

- Bottom Plate

This is one of two frequently encountered clogged piles. In this case, the bottom end is welded with a steel plate. The plate’s purpose is to compress and increase friction in order to prevent sliding. These are employed in rocky terrain when the rock and the pile are separated by a thin layer of dirt.

- Steel Pipe with Rock Shoe

This is the alternate type of plug. While rock shoes perform the same function as steel plates, they are employed in situations where the pile comes into direct contact with a rock surface. The shoe must be capable of supporting the entire load and preventing it from sliding down the rocky surface.

- Franki Piling Pipe

Franki heaps are intended to last a lifetime. They are plugged with a moist concrete infill and can endure far more impact from driving than their rivals.

production standard of pressure Pipe

ASTM A252 and ASTM A500 piling pipes are structural pipes that are well-suited for use in buildings, retaining walls, and other structures that require a robust, dependable, and high-quality steel piling pipe as a structural component.

Purpose of Installing Open-ended & Close-Ended Pipes

  • When met with barriers such as rock and boulders, open-ended pipes are expected to create an impact.
  • Open-ended pipes are more resistant to stress and damage.
  • Open-ended pipelines are frequently encountered on offshore gas platforms, oil platforms, and other locations.
  • Close-ended pipes are utilized to carry the load from the pile toe.
  • When your project is located in a sand area, close-ended pipes are employed.

Installation Methods for Piling Pipes

Piling pipes are installed in two primary ways: by driving piles or by drilling piles deeply into the ground. Each of these primary approaches can be accomplished by utilizing a variety of various procedures, depending on the type of Piling pipe utilized and the circumstances surrounding the installation.

- Driven Piling Pipes

Utilizing specialized machinery, steel pilings can be driven into the ground. Driving piles into the earth has an advantage over drilling shafts because the soil displaced by the piles compresses the surrounding soil, resulting in increased friction against the piles’ sides. This friction can be beneficial in increasing the load-bearing capacity of Piling pipes. Driven piles can be open-ended, allowing soil or sand to enter the tube, or closed-ended, preventing sand or dirt from entering the center of the piling. To strengthen stability and hold, steel piling pipes driven with one end closed may be filled with concrete.

- Drilled Piling Pipes

Drilled Caissons, drilled shafts, drilled piers, cast-in-drilled-hole (CIDH) piles, and cast-in-situ piles are all terms that refer to piling pipes. When this form of piling installation is employed, piles are driven into the ground with the assistance of rotary boring equipment. Rotary boring or drilling is frequently utilized to install big diameter piles and to create piles through dense or difficult geology. This method of installing piling pipes can be employed in both dry and wet ground conditions.

Common Benefits

A deep foundation is required for any structure that is expected to carry heavy loads. While there are numerous choices for providing structural support for deep foundations, steel piling pipes offer the most customization. Costs can also be reduced because they can be adjusted to exact load standards. Piling pipes eliminate the need for additional structural support, are easier and less expensive to erect, and may be inspected and verified for safety prior to installation. Additionally, they are among the easiest to expand upon the following construction, and they have some of the lowest replacement prices because of their resistance to cracking during the driving process.

When conditions permit, piling pipes have emerged as one of the best alternatives available in the industry for large load support. With the assistance of an expert, clients can ensure that these support systems are completely optimized for cost and safety.
