A method of manufacture of geotechnical profiles, characterized in that thermoplastic material, preferably hard and high-impact, PVC and/or PET and/or PE and/or ABS and/or PP, is plasticized in an extruder, after which it is pressed through an cross die unit ant internal reinforcing profiles (2, 4, 6, 8, 10, 12, 14, 16) in the form of flat bars, arched elements, angled elements, ribbed profiles or sections of any geometry are entered to it in the entire volume, and at least in selected cross-section areas of the geotechnical profile (1, 3, 5, 7, 9, 11, 13, 15), whereas these profiles are created from continuous and/or chopped fiber produced simultaneously or as part of a separate production process. A reinforced geotechnical profile, particularly a sheet piling profiles and a mobile flood prevention devices characterized in that it is manufactured out of thermoplastic material, in which reinforcement (2, 4, 6, 8, 10, 12, 14, 16) in the form of continuous fibers are entered locally or at least in selected cross-section areas, and then stabilized and maintained in position by a layer/coat made of PVC and/or PET and/or PE and/or ABS and/or PP, which is permanently and inseparably connected to the glass fibers.

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.

A temporary earth-retaining structure uses a guide bracket. Tensile force can be directly applied to a pile by using a guide bracket having a simple structure. Mudslide and collapse caused by the earth pressure of backfill soil can be more effectively prevented by means of the tensile force directly applied to the pile. In addition, the guide bracket according to embodiments of the present invention has a simpler structure and is more easily constructed than a conventional bracket, and thus can be constructed at very low cost.

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).
