A retaining wall installation process for earth and water retaining wall, first step starting from preparing precast reinforced concrete heavy duty retaining wall (1) on the ground, inserted horizontal rebars (12) at each fin (7) passed to the holes (8), connected mechanical couplers (14) only one end of horizontal rebars. Attached shuttle-platform (16) to precast reinforced concrete heavy duty retaining wail (1). Then lift up to installed the wall at construction site, put down the vertical rebars (15) connected to the lower vertical rebars by using mechanical couplers (14), tie vertical rebars to horizontal rebars, then closed the vertical cavities (24) by using panel closer (28) and poured fresh concrete (29). After final setting time, removed shuttle-platform down to the ground.

A system and method for forming scaffolding wherein the system comprises a plurality of upright columns arranged along a line adjacent to a vertical surface and anchored proximate to a base thereof and a platform supported by the plurality of upright columns. The method comprises anchoring a first set of a plurality of upright column segments by a base support proximate to a bottom of wall along a single line, extending a plurality of subsequent upright column segments from the first set of upright column segments to form a plurality of inline upright columns and supporting a platform from the plurality of upright columns.

The invention relates to a scaffolding arrangement with a scaffolding assembled from individual scaffolding components for internal construction or maintenance work within a coker drum standing upright on the ground and which has a lower end portion with a cross-section which tapers in the direction of the longitudinal axis of the drum towards a closable opening at the lower end of the coker drum, the scaffolding comprising: a support section with several support posts each having a lower and an upper end, the support posts, with their lower ends being supported outside of the coker drum on the ground and each of them, through the opening provided on the lower end of the coker, extending in a vertical direction into the coker drum, wherein the support section comprises several support posts spaced from one another, a support frame comprising a plurality of support beams which are detachably connected to one another, the support frame being attached to and supported by said support section, a first working platform which is arranged on top of the support frame, the first working platform being preferably located within the tapered lower end portion of the coker drum; and a scaffold tower section having one or more further working platforms which is/are each arranged in an axial direction above the first working platform inside the coker drum. The vertical loads of the scaffolding as a whole, are solely transferred to the ground via the said support section of the scaffolding, which is fully self-supported. The invention further relates to a scaffolding for an aforesaid scaffolding arrangement (FIG. 1)

The present invention relates to a support frame for use with an edge protection system for elevated structures, such as building rooves. The support frame includes a first frame portion and a second frame portion mounted together so as to be axially slidable relative one another between an extended position for locating a post of the edge protection system alongside a roof edge of a building and a retracted position. The support frame further includes a coupling mount extending from an uppermost frame member for coupling to a portion of the building adjacent the roof edge and for receiving and supporting the post in an upright position alongside the roof edge of the building.

The racking system comprises at least one rack and a mobile scaffold, the scaffold comprising a frame defining opposite first and second sides, a platform carried by the frame, for supporting a person above ground, a scaffold guide member carried by the frame on the first side, a rack guide member carried by the rack which is complementary to the scaffold guide member, with the scaffold guide member releasably engaging the rack guide member such that the scaffold is retained against the rack and is guided along the rack while allowing the scaffold to be movable along the rack, and a support member carried by the frame for allowing releasable support of the frame by either one of the rack and the ground. The frame is linked to a single rack of the racking system.

A plank scaffold system and, more particularly, to a ladder-based vertically-adjustable plank scaffold system. The system may have a pair of ladders, a wall standoff mounted at the top of each of the ladders, a crane support mounted at the top of each of the ladders, a vertical guide bar and roller system to keep it from swinging on the cables, and a horizontal platform suspended on cables below the crane supports, the platform having a pair of cable winches mounted thereon for varying the elevation of the platform. Instead of ladders, tower scaffolds or stage towers may be used on each side to support the vertically-adjustable plank.
