  • Patent number: 5152639
    Abstract: A tubular footing form of the recoverable type for building concrete foundation piles comprises an end shutting organ destined to prevent water from the water bed from entering the footing form while the latter is being plunged into the ground and to enable the concrete casting to be performed during the step of recovery of the same footing form. The end shutting organ is installed inside the tubular footing form at a certain distance from its free end so as to create a seal chamber which, during the step of plunging of the footing form, gets filled with compacted earth, which forms a plug which tightly seals the shutting organ against the entering of water from the water bed.
