MacArthur pile :
Basic information of MacArthur pile:
(See figure for better understanding of the concept.)
The pile has uniform diameter throughout its length and made from corrugated steel called Mac Arthur pile.
It is used in place of the Raymond pile.
1)Heavy steel casing with the dense core is driven into the ground.
2)After reaching a suitable height, only the core will remove.
3) Concrete is poured into these steel casing and compacted. Then steel casing also remove.
This is one of the types of pile foundations used in the present scenario.
A patented pile formed by driving a steel shell into the ground to the required depth, putting in small quantities of concrete, and hammering them down so as to force the concrete into the earth beyond the point of the shell; thus enlarging the end and greatly increasing the bearing area, is called mac-arthur piles. The shell is afterward withdrawn gradually, as the hole that it made is filled with concrete. If the shell were left in, the method would be far more satisfactory; as the shaft of the pile is liable to be seriously imperfect. Same as pedestal pile.
Such pilings, of course can only be driven into mud, sand or clay bottoms. The author suggests the pile would be more effective, were the steel casing to be left in place – which suggests that this sort of pile would only be used where the cost of supplying enough casings for all the piles would be higher than the additional labour involved in extracting the casins.
Mac-Arthur pile is a pile of uniform diameter and made of from using corrugated sheet shell which remains in place as Raymond pile.
1. First of all heavy corrugated steel shell is driven with the core.
2. After reaching desired depth the core is withdrawn from that sheet pile.
3. Concreting is done after the withdrawal of the core.
Mac Arthur pile is a cast In-Situ pile of uniform diameter.
Mac-Arthur pile is a pile of uniform diameter pile. made of from using corrugated permanent sheet shell.
Mac-arthur piles are the heavy steel casing with a core is driven into ground. When the desired depth is reached, the core is withdrawn and a corrugated steel shell is placed in the casing. The last operation consists in filling and gradually compacting the concrete and withdrawing the casing.
