A base (1a, 1b, 1c) for building wall (10a, 10b, 10c) comprising: a base socle (3a, 3b, 3c) interposed, in position, between a panel (2) of the wall (10a, 10b, 10c) and a foundation slab, a tubular member (5) filled with a mixture (6) including cement and water interposed, in position, between the base socle (3a, 3b, 3c) and the foundation slab, first constraint means (7a, 7c, 8, 9, 11) to rigidly constrain, in position, the base socle (3a, 3b, 3c) to the foundation slab; the planimetric position of the base socle (3a, 3b, 3c) and its distance from the foundation slab being adjustable by means of said first constraint means (7a, 7c, 8, 9, 11), second constraint means (7a, 7b, 7c, 12, 13) to rigidly constrain, in position, said panel (2) to said base socle (3a, 3b, 3c).

Systems and method are provided to protect devices from damage due to floodwaters. For example, a system includes a floating platform assembly, an apparatus securely disposed on the floating platform assembly, first and second platform retaining members connected to the floating platform assembly, and first and second vertical support members disposed on opposite sides of the floating platform assembly. Upper ends of the first and second vertical support members are connected to an outer sidewall of a dwelling, and bottom ends of the first and second vertical support members are fixedly secured at ground level. The first and second platform retaining members insertably receive the first and second vertical support members, respectively. The first and second platform retaining members are configured to slide along the respective first and second vertical support members when the floating platform assembly vertically rises and lowers in response to a changing level of floodwater.

A device for 3D or 4D printing of reinforced foundations in geotechnical engineering comprises a driving system (50) for positioning of the production unit (7) in a three dimensional space (x, y, z) on a construction site (1). The production unit (7) comprises a first production assembly (20) and a second production assembly (30), wherein the first production assembly (20) and the second production assembly (30) are designed to operate with different construction materials, wherein one of said construction materials is a reinforcement construction material for reinforcing the foundations to be created during operation of the device.

A height-adjusting apparatus for a mobile foundation includes a rod with a threaded portion and a threaded plate, which is retained in an adjustable manner on the threaded portion and has a supporting surface. The height-adjusting apparatus also includes a tube, which has a cavity. The tube comprises at least one wall aperture on an outer side, as a result of which the rod projects into the cavity. Additionally, the height-adjusting apparatus is configured such that the rod can be rotated relative to the tube at least in part about an axis parallel to the longitudinal axis of the tube.

A waterproof structure for a panel joint of an underground diaphragm wall includes a first waterstop and a first cover plate. The panel joint is provided with a wall connection plate. The underground diaphragm wall has an excavation surface. In a direction perpendicular to the excavation surface, the wall connection plate is arranged below the excavation surface of the underground diaphragm wall. A first accommodating groove is defined between the wall connection plate and the panel joint and adjacent to the excavation surface. The first waterstop is arranged in the first accommodating groove, and both wings of the first waterstop are respectively and adhesively bonded to the two sides of the panel joint. The first cover plate corresponds to the first accommodating groove and is arranged at the excavation surface. The first cover plate is detachably connected to the underground diaphragm wall.

This anchor support tool supports an anchor provided in a foundation, the anchor support tool comprising: a support plate having at least one support part for supporting an anchor; a spacer for positioning the support plate with respect to a form of the foundation in the height direction; and a fixing jig for fixing the support plate to the form. The fixing jig supports the support plate while the support plate is disposed above the form with the spacer therebetween.

A post-tensioning system that is configured for use with concrete wind turbine foundation designs to post-tension the foundations and reduce the amount of reinforcement steel that is needed compared to conventional non-post-tensioned, steel reinforced concrete foundation designs. In the case of an inverted T gravity foundation, the post-tensioning system described herein reduces the amount of reinforcement steel that is required by 30-40 tons.
