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 disclosure provides a building construction system and method for preventing the moisture of soil from reaching floor or foundation of the building. The method includes steps of digging in soil for piles to a depth determined based on soil nature, raising plurality of concrete piles from the depth to a height above the ground/grade, connecting the piles using steel beams and placing transversal members between steel beams allowing for blocks to be placed between the transversal members to define a surface wherein concrete can be poured creating a raised foundation floor.

The invention provides a method for preventing super large-scale floods and debris flows. First, the scale corresponding to certain standard floods in the watershed is evaluated based on field investigations and historical data. Second, the design standards of the system are chosen based on the prevention of super large-scale floods, and the design standard of critical control engineering is further determined. Finally, the design methods of check dams with different functional zones are proposed according to the design standards of critical control engineering. The invention allows part of the key control dam to fail under safe operating conditions of the entire system by increasing the cross-sectional areas and the flow discharges. The unbroken foundation of the dam can effectively control the channel entrainment and regulate the cross-sectional discharge. The design is helpful in mitigating giant floods and debris flows, thus protecting downstream infrastructures.

A floating foundation assembly includes a plurality of piers and one or more decks. The plurality of piers are screwed into or otherwise secured to a ground surface at predetermined distances from each other, at predetermined depths. The one or more decks include a precast prestressed deck with standardized geometries. The one or more precast prestressed decks are installed transversely across tops of the plurality of piers and are configured for affixing a structure above them. The one or more precast prestressed decks are manufactured in a controlled environment at an off-construction site, after which they are transported to a construction site and installed on top of the plurality of piers to form the floating foundation assembly. These resulting decks and supporting floating foundation assemblies have superior quality, durability, weatherproofing, and crack resistance.

A machine for driving a pair of screw anchors at substantially the same time. An attachment supports a pair of independent drive assemblies. Each assembly consists of a rotary driver and tool driver that moves along respective driving arms to independently drive a pair of screw anchors into supporting ground at different angles. Each assembly may move with respect to the machine independently to drive anchors into the ground in overlapping time, or both may rotate at once to drive anchors into the ground sequentially.
