A measuring apparatus for measuring a structure comprises at least one measurement sensor configured to measure the structure, a bearing platform configured to carry the at least one measurement sensor and a control. The control is configured to specify at least one quality reference value for at least one characteristic of measurement quality, and further configured to adjust one or more parameters of the measuring apparatus which influence the at least one characteristic of measurement quality. An actual quality value is determined and approaches the at least one quality reference value as the one or more parameters are adjusted.

A retaining wall for retaining matter on a side thereof comprising: a plurality of upwardly projecting primary sheet piles spaced apart from each other and having first structural properties comprising at least one of weight, size, strength and depth to be installed in a supporting body; and one or more intermediate panels of material arranged so as to span the gap between a pair primary sheet piles and to retain at least a portion of the retained matter, wherein the one or more intermediate panels have second structural properties different from the first structural properties.

A system that includes a plurality of front faces configured to be arranged end-to-end in a series. Adjacent front faces are connected together by a different X-shaped or X-wye connector that facilitates installation of reinforcement tail walls. At least one tail wall is connected to each connector. A redundant reinforcing tail wall may be constructed and attached to one of the connectors to provide alternative load path(s).

A method of manufacture of geotechnical profiles where thermoplastic material including one or more of polyvinyl chloride (PVC), polyethylene terephthalate (PET), polyethylene or polythene (PE), acrylonitrile butadiene styrene (ABS), or polypropylene (PP), is plasticized in an extruder, pressed through a cross die unit and internal reinforcing profiles in the form of flat bars, arched elements, angled elements, ribbed profiles or sections of any geometry are entered at least in selected cross-section areas of the geotechnical profile where the internal reinforcing profiles are created from one or more of continuous or chopped fiber produced simultaneously or as part of a separate production process.

A sheet pile of concrete comprising a reinforcement (1) which is produced from composite material comprising fibres and a concrete casting (2) which extends between a first lateral end (3) thereof and an opposite second lateral end (4) thereof, the reinforcement (1) being embedded in the concrete casting (2). The sheet pile further comprises a terminal element (6) which is produced from a polymer material and which comprises a connection element (7) which is embedded in the concrete casting (2) and an engagement element (8) of the sheet pile (100) which is connected to the connection element (7). The connection element (7) and the engagement element (8) extend along a longitudinal axis (X) of the sheet pile, in which the engagement element (8) has a practically C-shaped cross-section and projects from the first lateral end (3) of the concrete casting (2). The second lateral end (4) of the concrete casting (2) comprises a concrete joint (9) which extends longitudinally along the longitudinal axis (X) and which is shaped so as to be connected in an interlocking manner to the engagement element (8) of a second sheet pile.

A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.
