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 concrete building block includes indicators along each end to assist in aligning a pin placed in the block with a channel in a like block in a course below as a wall is being constructed.

A groundworks method for a foundation designed to form a foundation slab for an onshore wind turbine includes: excavating in the soil a depression intended to receive, on the one hand, an anchoring means which will be used to connect the mast to the future foundation and, on the other hand, the pouring of concrete to form said foundation after setting. According to the invention, the method further comprises digging a trench at the center of the depression, placing a compressible material in this trench, covering said material with a layer of concrete and waiting for it to set. A foundation is built for a wind turbine, by pouring concrete, the central part of which does not bear on the soil or barely bears on the soil. As a result, the pressure on the soil is increased and is delimited over a peripheral annular zone situated around its central part.

To provide a technology for manufacturing a foundation of a plant efficiently and safely. Provided is a method for manufacturing a foundation (6) to be provided in a plant configured to process fluid, the method including a step of forming a foundation, by a 3D printer, in a ground for installation of a device to be provided in the plant, or in a ground for installation of a framework structure configured to support the device or a piping through which the fluid flows, the foundation being configured to support the device or the framework structure.

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.

A novel wind turbine, the tower of which ending with three legs and which is also anchored to the ground by means of a characteristic anchoring system depending on the type of existing soil. It is anchored on conventional rock soil with a pile foundation, it is anchored in a hard-rock soil with an anchor-rock foundation, it is anchored in a non-rocky soil with a gravitational foundation and it is anchored on clayey or swampy soil with a gravitational foundation reinforced with piles.

A sheath for constructing a reinforced concrete pile, characterized in that the sheath is formed by at least one circular knit comprising having a series of meshes helically positioned so as to form a pipe. A method for constructing a reinforced concrete pile includes excavating to form a well, inserting one end of a reinforcing rod in a sheath, positioning the sheath on an area of the rod and introducing the rod into the well, installing a tremie pipe inside the rod, and filling the well with concrete using the tremie pipe.

An offshore wind energy system comprising a foundation having a first hollow structural element with a longitudinally extending, circumferential first wall. A cable bushing penetrates through the first wall and is arranged in the first wall. At least one cable guide arrangement extends in a radial direction and is arranged at an outer shell surface of the first wall of the first hollow structural element. The cable guide arrangement is configured to guide a submarine cable exiting the cable bushing from the cable bushing to a submarine bottom surface.

The invention relates to a method and a device for producing a foundation element in the ground, wherein a hole is formed in the ground which is filled with a hardenable filling mass in order to form the foundation element. According to the invention provision is made in that prior to the hardening of the filling mass a data carrier is introduced into the hole, on which information on the produced foundation element is stored .

A method for constructing an assembled recyclable rectangular working well with preset detachable door openings comprises steps of: (I) designing according to functional requirements for a rectangular working well; (II) constructing by supporting piles; (III) installing prefabricated top beam; (IV) edge protection construction; (V) alternate construction of earthwork excavation, retaining slabs and internal support breast beams; (VI) installing the ladder entering the rectangular working well; (VII) rectangular working well back cover; (VIII) demolition of the detachable subsection support piles in the door part and completing the construction of the assembled recyclable rectangular working well in the preset detachable door hole; (IX) after the operation in the well is completed, during the backfilling process of the rectangular working well, gradually recovering the working well components such as the retaining slab, the internal support girder, the prefabricated crown beam and the supporting piles.
