Disclosed are embodiments of a method for manufacturing concreate panels for a mechanically stabilized earth (MSE) retaining wall that employ geosynthetic strips that attach to the MSE retaining wall and extend into the backfill soil. One embodiment can be generally summarized as follows: (a) providing a mold for the concrete panel; (b) providing in the mold: (1) a plastic pipe; (2) a metal rod situated in the pipe; (3) a removable block-out insert that creates a geosynthetic strip cavity within the panel body around the pipe for enabling a geosynthetic strip to be looped around the pipe; (c) introducing concrete into the mold; (d) permitting the concrete to substantially solidity within the mold; and (e) after the concrete has substantially solidified, separating the panel from the mold and removing the block-out insert to expose the cavity and the pipe extending through the cavity.

The present disclosure relates to a soil displacement drill comprising a drill pipe; a widening at one end of the drill pipe that is provided with (1) a screw blade for screwing the drill into the substrate, and (2) an outlet opening for the passage of material that is introduced for forming the foundation pile; and a flap that is movable between a first position for allowing unhindered screwing of the drill into the substrate and a second position for preventing the material from entering a screw groove. The screw groove is formed in the substrate by the screw blade during unscrewing of the drill from the substrate. The disclosure further relates to a method for forming a smooth foundation pile using such a drill.

The present invention relates to a rock anchor foundation structure suitable for a mountain photovoltaic module and a construction method of the rock anchor foundation structure. A technical solution of the present invention is as follows: the rock anchor foundation structure comprises a drill hole drilled in a rock slope, an anchor rod module arranged in the drill hole and a photovoltaic power station module. The photovoltaic power station module is connected with the anchor rod module through a hollow connecting steel pipe; the photovoltaic power station module comprises a bracket welded on the top of the hollow connecting steel pipe, a beam mutually hinged with the top of the bracket and a photovoltaic cell panel arranged at the upper part of the beam. The rock anchor foundation structure of the present invention is suitable for the technical fields of around treatment and foundation engineering design.

A foundation pile comprising a longitudinal through hole (1) and a plurality of crosswise through holes (2) transverse to longitudinal through hole (1) extending between longitudinal through hole (1) and the outer surface of the pile and optionally further comprising check valves positioned in the crosswise through holes (2), configured such that the crosswise through holes (2) and the check valves allow one-way communication from the inside of the pile to the outside of the pile from longitudinal through hole (1) to the outer side surfaces of the pile.

A foundation forming arrangement is provided for forming a foundation slab. The foundation forming arrangement includes at least one side forming member for forming a side of the foundation slab. The foundation forming arrangement further includes at least one connector that is configured for coupling the side forming members to either a reinforcing steelwork or a forming pod. The foundation forming arrangement can further include a drain, as well as an insulative panel. The foundation forming arrangement can include a forming pod that is configured for connection to the side forming members. The foundation forming arrangement can include securing arrangements for securing the connectors to the top or the base of a forming pod.

A formwork element for a molded wall panel end, comprising: a sole plate having a first lateral edge, a second lateral edge, an outer face, an inner face bearing a caisson, said caisson leaving free, on the inner face of the sole plate, a first lateral zone, defined between the first lateral edge and the caisson, and a second lateral zone, defined between the second lateral edge and the caisson; a form stripping assistance device cooperating with the sole plate. The form stripping assistance device includes at least one first sacrificial section comprising a first portion disposed on the first lateral zone of the inner face of the sole plate.

A membrane-lined wall for levee reinforcement or leak prevention, prevention of water migration, and pollution control of impoundments. The membrane-lined wall generally includes a cementitious or concrete wall formed within an excavated trench. The concrete may be internally reinforced, and the wall may also comprise a double-layer of impermeable geomembrane liner that forms a barrier between the concrete and the sides and bottom of the trench. The membrane or liner reduces water migration, prevents levee leakage, and prevents the escape of contaminants in impoundments.

Various embodiments of an adjustable mold are disclosed for forming a precast concrete top panel for a modular earth retaining wall, for example but not limited to, a modular mechanically stabilized earth (MSE) retaining wall. The adjustable mold has a support base with a top surface, bottom surface, and surrounding periphery. A plurality of rails is mounted to the support base and upstand generally perpendicular from the support base. The rails are collectively attached together to form a closed lateral side boundary with an open top designed to receive liquified concrete. The support base and rails are designed to form sides of the precast concrete top panel. The rails can be adjusted to change a geometric shape associated with the closed lateral boundary in order to enable production of different top panels having different lateral boundaries, and therefore geometries.

A method and apparatus for forming cemented ground support columns is disclosed. Namely, driving mandrels are provided for the efficient construction of incrementally enlarged diameter support columns. For example, the driving mandrel includes a feed tube that has a top portion and an expansion head portion. The expansion head portion further includes an expansion (or compaction) chamber and a flexible tubular egress port. Further, construction methods are provided of using the driving mandrels for the efficient construction of incrementally enlarged diameter support columns.

A modular foundation assembly for building a modular foundation for a home includes a tarp that has a plurality of openings each strategically positioned on the tarp to facilitate the ground to be marked for a foundation. A plurality of concrete forms is provided which each has a trapezoidal shape. In this way each of the concrete forms can be lifted upwardly from a concrete member formed by the concrete forms when the concrete member has cured. Each of the concrete forms has a crenellated edge to form a series of slots into the concrete member. In this way the series of slots in the concrete member facilitate the concrete member to be lifted with a forklift.
