Extensible shells and related methods for constructing a support pier are disclosed. An extensible shell can define an interior for holding granular construction material and define a first opening at a first end for receiving the granular construction material into the interior and a second opening at a second end. The extensible shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the extensible shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the extensible shell to form a support pier.

The present invention relates to a pile foundation including: a pile that extends in a vertical direction, and whose pile head protrudes above the ground, and that supports a tower-type structure, and ribs that are provided at the pile in a vicinity of a surface of the ground, and that protrude outwardly in radial directions from an outer circumferential surface of the pile.

A foundation system for manufactured homes, prefabricated houses, and other structures. Multiple screw anchors are driven into the ground at the desired location of the structure. Preformed grade bars may be placed over the screw anchors to provide a modular foundation without pouring concrete or digging footers. Alternatively, adapters may be attached to one or more of the driven screw anchors to provide a pedestal to receive the grade bar or prefabricated sections of concrete

The present invention discloses a pile foundation permeable breakwater with variable permeability, comprising: two rows of prefabricated pile foundations. The tops of the prefabricated pile foundations are fixedly provided with a prefabricated panel. The top of the prefabricated panel is provided with a wave wall and a breast wall. The prefabricated pile foundations are integrally connected with fixed wave breaking plates; sliding rails are installed correspondingly on the top and the bottom between every two adjacent prefabricated pile foundations in the same row; and movable wave breaking plates are slidably connected between each pair of sliding rails. A control system for controlling the slide of the movable wave breaking plates is installed on the prefabricated panel. The present invention also discloses a construction method of the pile foundation permeable breakwater with variable permeability.

The rapid consolidation and compaction method comprises (i) first driving a hollow pipe, (ii) driving a pipe with a removable end plate after filling and compacting the sandy material in it, through the hollow pipe, to required depth, creating high excess pore-water pressures in the range of 50 to 300 KPa in clayey soils, (iv) pulling out the pipe section leaving behind the removable end plate and thereby installing porous displacement piles which allows dissipation of the excess pore-water pressures horizontally to the porous displacement pile, in which the excess water flows out vertically to the ground surface, and (v) the length of the drainage path is reduced to half the spacing between adjoining porous displacement piles, allowing rapid consolidation resulting in increase in density. Installing the porous displacement piles in the layer of loose to medium dense sand layer results in the instantaneous increase in its density.
