The invention relates to a soil working device for creating a substantially vertically running hole in the ground, which hole is provided with a slurry, said soil working device having a base body, a connection apparatus which is arranged on an upper end region of the base body, and a soil removal apparatus and/or a soil displacement apparatus, which is arranged on a lower end region of the base body. According to the invention is intended that, at a lower region of the base body, a first pressure measuring apparatus for measuring a first ambient pressure is arranged, and that at an upper region of the base body, which is vertically spaced apart from the lower region, a second pressure measuring apparatus for measuring a second ambient pressure is arranged. The invention also comprises a method for creating a substantially vertical hole in the ground by means of such a soil working device.

A pile driver driven foundation bracket system includes a foundation bracket drive unit and a foundation bracket unit. The foundation bracket drive unit includes a pile driving unit interface configured to engage with a pile driving unit, a hollow sleeve, and a foundation bracket drive interface. The pile driving unit interface is connected to a first end of the hollow sleeve, and the foundation bracket drive interface is connected to a second end of the hollow sleeve. The foundation bracket drive interface is removably connected to the foundation bracket unit. The foundation bracket unit includes a horizontal foundation bracket support arm, a foundation bracket brace having an opening, the opening being configured to allow soil to flow therethrough when the foundation bracket unit is rotated, and a foundation bracket hollow sleeve.

Soil displacement piles having a shaft and one or more soil displacement assemblies secured to the shaft are provided. If more than one soil displacement assembly is utilized, each soil displacement assembly is separated by a longitudinal distance. Each soil displacement assembly has an upper helical plate, a lower helical plate and separated from the upper helical plate by a longitudinal plate distance, and at least one soil displacement plate positioned relative to the shaft, the upper helical plate and the lower helical plate.

A system for forming a movable slab foundation has a slab foundation, at least one support surface, at least one lifting member, at least one support sleeve, and an engagement device carried by the at least one support sleeve. The at least one support sleeve is encased within the slab foundation and its lower end is positioned in abutting contact with the at least one support surface. The at least one lifting member is inserted through the at least one support sleeve. The at least one support sleeve and the slab foundation are moved upward axially along the length of the at least one lifting member. The engagement device is engaged with the at least one lifting member, thereby securing the slab foundation and the at least one support sleeve at a desired height.

A telescopic shoring system for shoring open excavations comprises rail posts composed by at least an outer member and an inner member, and large shoring panels. Each outer and inner member of the rail post has laterally, on either side, at least one panel guide allowing the shoring panels to slide within. The outer member of the rail post has a frontal guide adapted to interlock the back guide provided to the inner member but sliding relatively to each other. The shoring panels are arranged on each side of the excavation while the rail posts are placed on each corner holding on either side the shoring panels, which create a multi-stepped shoring box. The outer members of the rail post with shoring panels create an outer or upper shoring box while the inner members of the rail post in combination with shoring panels create an inner or lower shoring box.

The invention concerns a recoverable gabion for use in protecting military or civilian installations from weapons assault or from elemental forces, such as flood waters, lava flows, avalanches, soil instability, slope erosion and the like. The gabion comprises opposed side walls comprising a plurality of side wall elements connected together at spaced intervals by a plurality of partition walls such that spaces between neighbouring pairs of partition walls define, together with the side walls, individual compartments of the gabion, adjacent side and partition walls being connected to one another by pivotal connections enabling the gabion to be folded between fully flattened and deployed configurations, wherein at least one of the pivotal connections is a releasable connection which when released allows a side wall element to open with respect to the gabion to allow access from the side of the gabion to any contents of the gabion compartments.

A connection element for light profiles in a sheet pile wall has a base strip (12) for attaching to a component of the sheet pile wall and a hook strip (14) provided at the flat side of the base strip (12) for engaging the interlock (32) of a light profile (30). The hook strip (14) that encloses an inner chamber (16) exhibits a straight connection section (20) that originates at the base strip (12) and runs at least approximately at a right angle to the longitudinal direction of the base strip (12) and a hook section (22) that follows the connection section (20) and runs in an arc-like manner for at least 180°, with the free end of said hook section (22) together with the flat side of the base strip (12) defining a jaw (28). According to the invention, the ratio between the greatest inner width (a) of the inner chamber (16) of the hook strip (14) to the width (c) of the opening jaw (28) is in a range between 2.6 and 2.9.

Disclosed is a stackable mine rock shield. The mine rock shield includes a body having a first surface and a second surface, an aperture positioned at about the center of the body for receiving a fastening mechanism, a continuous protuberance extending outwardly from the first surface of the periphery of the body and defining a recess wherein the continuous protuberance intersects the first surface of the body to form an angle of intersection with such first surface, and an edge portion at the perimeter of the body. The mine rock shield may further include a rigid notch at the periphery of the body.
