Basement shoring apparatus has a modular panel having a panel body having a plurality of parallel drill rod shafts therethrough. Each drill rod shaft has a respective drill rod rotatably engaged therein. Each drill rod extends from a lower edge of the panel body and has a respective auger or cutting head attached at a distal end thereof. Each drill rod is connectable via an upper edge of the panel body for turning. Adjacent drill rods extend to different extent such that blades of respective augers overlap adjacently. As such, modular panel can be drilled into the ground to form shoring wall.

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 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 process for installing a modular retaining wall is illustrated and described having open or closed polygonal modules with channels disposed therein. The wall is set at least partially below a surface, the surface either being land-based or aqueous-based, and interfaces therebetween, e.g., shoreline. The modules of the wall are fastened to each other by respective fastening mating fasteners. The retaining wall is installed by a process employing a fluid-assisted internal mandrel.

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.
