    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 When the desired depth is reached, the core is withdrawn and a corrugated steel shell is placed in the casing.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.

    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 The shell is afterward withdrawn gradually, as the hole that it made is filled with concrete.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.

    What are Mac-Arthur Piles?

    MacArthur pile :

    Definition :

    • It is a patented pile.
    • It is formed by driving a steel shell into the ground to the required depth.

    Basic information of MacArthur pile:

    • It is placed in small quantities of concrete and having them down.
    • The purpose is to force the concrete into the earth beyond the point of the shell.
    • Its an advantage is that the bearing area is increases as same as pedestal pile
    • Then the Shell is withdrawn because the hole is made is filled with concrete

    (See figure for better understanding of the concept.)

    Thank you.

    Mac-Arthur pile is a pile of uniform diameter pile. made of from using corrugated permanent sheet shell.

    Procedure:-

    1. heavy corrugated steel shell is driven.
    2. After reaching desired depth the core is withdrawn from that sheet pile.
    3. Reinforcement placed before concreting.
    4. Concreting is done after sheet pile withdraw.

    Mac Arthur pile is a cast In-Situ pile of uniform diameter.

    1. A shell casing is driven into the ground with the help of a driving core.
    2. After the desired depth is reached, the core is removed.
    3. Now a corrugates steel shell is inserted again into the casing.
    4. The concrete is poured into the corrugated steel shell and simultaneously the outer casing is removed.
    5. If the outer casing is left inside, the structure would be even more safe but it is not economical.

    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.

    Procedure:

    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.

    Mac-Arthur pile is a pile of uniform diameter and made of from using corrugated sheet shell which remains in place as Raymond pile.

    Procedure:-

    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.
