What is raymond pile?

The Raymond pile, invented in 1897, is one of the oldest pile types, but still used in several countries, especially North America.

The Raymond pile is also known as the "Step-taper pile", due to the special steel shell and the typical mandrel. Step-tapered piles are formed from 1. 2, 2. 4, and 4. 9 m straight-sided, thin-walled segments of spirally corrugated steel. Each successive pile.

Element decreases over a length of 2. 44 m by 25 mm in diameter. The minimum diameter (at the pile toe) is 0, 212 m. Step-tapered piles can be driven to a maximum depth of about 40 m. The 40 m long pile has a tip diameter of 0, 212 m and a shaft diameter (at the ground surface) of 0, 438 m.

The pile is installed using a unique driving process. A specially shaped mandrel is inserted into a thin-walled pile tube and the driving force is transmitted along the casing and to the bottom of the pile. In this way, the wall thickness of the pile tube can be kept to a minimum.

In which type of structures Raymond Piles are being used?

A form of filling pile in which a steel shell is driven into the ground and allowed to remain, at the time of withdrawing the mandrel, so as to form a lining for the hole into which the concrete is poured.

The Raymond concrete pile is constructed in place. A collapsible steel pile -core is encased in a thin, closely-fitting, sheet- steel shell. The core and shell are driven to the required depth by means of a pile -driver. The core is so constructed that when the driving is finished, it is collapsed and withdrawn, leaving the shell in the ground, which acts as a mould for the concrete. When the core is withdrawn, the shell is filled with concrete, which is tamped during the filling process. These piles are usually 18 inches to 20 inches in diameter at the top, and 6 inches to is usually No. 20 gauge. When it is desirable to reinforce these piles, the bars are inserted in the shell after the core has been withdrawn and before the concrete is placed.

8 inches at the point. When it is desirable, the pile can be made larger at the small end. The sheet steel used for these piles.

Raymond Pile:

A pile made by driving a thin steel shell into the ground with a tapered mandrel and filling it with concrete.
