A foundation for wind turbine towers of the type used to support both metal towers and concrete towers of wind turbines that uses precast concrete or metal beams, combined with small footings concreted in situ, the beams being structurally connected at the central part of the foundation by the elements of connection and of support of the tower is disclosed. The invention affords the main advantage of achieving a notable reduction in the volume of materials used, both concrete and rebar, with a great reduction in assembly time and the consequent great economic savings as well as its ease of adaptation to different terrains is presented.

A permanent form (13) serving to form concrete structures and comprising sidewalls (11) comprises: an interior form (14) that forms the inner face of a side wall; an exterior form (16) that forms the outer face of the sidewall; and a plurality of vertical reinforcements (17) that are disposed between the interior form and the exterior form and that hold the exterior form alone or together with the interior form. The exterior form and the interior form have: a plurality of base plates (18) that are formed from plastic into square plates and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; a plurality of central reinforcement plates (19) that are formed from plastic into square plates substantially equal in size to the base plates, that join four adjacent base plates, and that are aligned so as to be in firm contact with each other in the vertical and horizontal directions; and a plurality of end reinforcement plates (21) that are formed from plastic into rectangular plates are arranged into a quadrangular frame so as to join adjacent base plates while being located on the outer edges of the plurality of central reinforcement plates aligned so as to be in firm contact with each other in the vertical and horizontal directions.

An adjustable railing post-to-substrate embed system for anchoring a railing post having a railing base with plural railing base anchor holes includes: a plate, having anchor holes; a plurality of nuts, a first end of each nut being arranged proximate a respective one of the anchor holes, the first end of each nut being configured to be selectively and removably threadingly engaged, via the respective anchor hole, with one selected from the group consisting of: respective upper protective bolts, and respective bolts of the railing base; and a plurality of anchors, each being configured to adjustably threadingly engage a second end of a respective one of the nuts, distal the respective anchor hole, each of the anchors being individually adjustable in length by threadable engagement with the second end of the respective one of the nuts.

The invention relates to a foundation engineering machine and a method for producing a trench in the ground with a foundation engineering machine having a substantially vertical mast, a diaphragm wall apparatus which is displaceably supported in the longitudinal direction of the mast for producing a trench in the ground, and a bar-shaped holding means, at the lower end of which the diaphragm wall apparatus is mounted and with which the diaphragm wall apparatus is linearly displaceable along the mast. According to the invention provision is made in that on the mast an upper first clamping sledge with a first clamping means for releasably clamping the bar-shaped holding means and a lower second clamping sledge with a second clamping means for releasably clamping the bar-shaped holding means are movably supported and the first clamping sledge and the second clamping sledge are movable relative to each other and in that the lower second clamping sledge is provided with a connecting means for mounting an additional lifting device which is arranged on the ground and with which a force can be applied in the longitudinal direction onto the second sledge.

A foundation system (1) and method of installing the foundation system. The system including plurality of modular slabs (3, 3A, 3B) mountable onto a gravel layer (2); and at least one horizontal isolating slab (5A, 5B, 5C) and a vertical edge portion (4) positioned with respect to the modular slabs (3A, 3A, 3B) for creating a receptacle wherein concrete is poured thereon.

A device that compensates for abrupt variations in fluid flow rate for a pump line is described. One or more aspects pertain to a system to accomplish automated in-situ placement of a concrete wall or embankment, where a fluid concrete is pumped into place, consolidated, and screeded to a finished surface, with remotely controlled or automated equipment.

A tensionless concrete pier foundation for supporting a tower and a method of constructing the same is provided, the foundation having an outer CMP and an inner CMP with an annular space therebetween in which a plurality of sleeved tower anchor bolts are embedded, at least the outer CMP having an upper edge that is flush with the top of the foundation after the tower has been installed. A method of plumbing a tower anchor bolt cage using a bolt alignment ring is also provided that includes coupling the upper ends of the CMPs together with lateral spacing bolts that extend across the annular space. The tower anchor bolt cage is suspended from the lateral spacing bolts by the bolt alignment ring, and the lateral spacing bolts are shimmed on a low side as necessary for leveling the alignment ring and plumbing the bolt cage, before concrete pour.

A barbed micropile for soil reinforcement at a target location and a method for soil reinforcement at a target location. The barbed micropile includes a conical-head pipe which comprises a hollow rod, a conical head, and a first plurality of T-shaped elements mounted around an outer surface of the hollow rod. The method may include generating a cavity at the target location, filling the cavity with grout, generating a well at the target location by inserting a barbed micropile into the ground at the target location, filling a space between the barbed micropile and the well's wall with grout, and filling an inner chamber of the hollow rod.

A foundation for a tower structure, in particular for a tower of a wind power installation, comprising a soil improvement unit with piles and with a slab which is arranged on the piles and which has a foundation side, wherein the foundation side forms a foundation plane, and a shallow foundation which has an areal standing side for mounting onto the foundation plane, wherein the shallow foundation is arranged on the slab.

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.
