    摘要: Provided is a method for burying a precast pile in which a borehole and a buried precast pile are strongly integrated, the end bearing capacity and the circumferential frictional force of the precast pile are increased, and the extraction resistance strength thereof is improved. Provided is a method for burying a precast pile in which a foaming agent having an expanding effect is added to the cement milk or mortar in advance, whereby the soil cement formed around the base of the precast pile in the borehole is caused to expand.

    摘要: A method for installing a pre-cast/pre-stressed concrete and steel pile used in the construction of pile foundations and the resulting installed pile that has its distal end anchored to bedrock is disclosed. After the pile is located on bedrock, a first hole is drilled into bedrock that is of sufficient depth to accommodate a lower portion of the steel pipe that extends below the concrete pile and contains a plurality of orifices. A second hole is drilled into bedrock that is below and concentric to the first hole and has a diameter than that is usually less than that of the first hole. The second hole forms an anchoring socket to accommodate an anchoring anchor. Grout is injected into the steel pile and anchoring socket until the grout fills the voids in the interior of the steel pipe. Grout also seeps through the orifices in the lower end of said steel pipe and fills the second hole, and an annular space between the outer circumference of the steel pipe and the walls of the first hole.

    摘要: The invention concerns a reinforcement unit for reinforcing a footing element by laying pile foundation with a foundation pile with at least one through-going longitudinal cavity, where the reinforcement unit includes a number of shaped and articulated reinforcement members that are pivotably connected to a centrally arranged, annular element, so that the reinforcement unit has a folded mounting and an extended position of use, and that the reinforcement unit is connected to the foundation pile by one or more tension members. The invention also concerns a method for placing a foundation pile and reinforcing a footing element with a reinforcement unit.
