A pile connection comprises at least one fixture having a collar portion, a plurality of micropile sleeves, a plurality of gusset members extending between the collar portion and the micropile sleeves, and at least one connecting member that couples adjacent gusset members and that is spaced apart from the collar portion. A recess bounded by a wall of the collar portion is configured to contact a portion of a vertical pile. One or more fasteners may be used to press the wall against the vertical pile, with certain embodiments employing two complementary fixtures that may be coupled to one another (e.g., using the fasteners) along opposing sides of the vertical pile. Each micropile sleeve is configured to receive a micropile that may be driven through the sleeve into the ground at a position spaced apart from the vertical pile.

The present invention relates to an erosion control apparatus and methods of using and installing the apparatus. The apparatus is constructed to prevent erosion of soil during typical weather or tidal conditions and adverse weather events. The apparatus can include a plurality of anchored rolls and soil lifts operative to stabilize the shoreline.

An assembly and method of simultaneously spin drilling and pressure grouting a helical anchor into the ground vertically, horizontally or at an inclined angle create a continuous grouting configuration inside and outside the helical anchor for its entire depth in the ground. The helical anchor is configured to be partially or completely removed as desired and can be provided at its upper end with a tensioning element to post tension a cementitious foundation structure. A unique spin drilling and grouting assembly continuously provides grout under pressure to the interior of the helical anchor during its spin drilling into the ground. In one embodiment, the pressure grouted helical anchor is used with an upwardly extending tensioning element to reinforce cementitious foundation caps or other concrete support foundations.

A reinforced 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, and the pier foundation including at least one reinforcement structure that at least partly encircles the outer CMP to provide one or more of increased lateral stiffness, increased shear resistance and overturning (upset) moment capacity, reduced bending, displacement, and deflection of the top of the pier, and improved conditioning, containment, skin friction and lateral bearing capacity of the surrounding soil and/or rock substrate that supports the tensionless pier.

Landscaping walls, systems and methods of manufacturing and installation of such walls include in aspects a fiberglass based wall having a decorative front side and a back side having at least one conduit where the conduit receives a cable or fastener extending outward from both ends of the conduit to connect to a stake to be inserted into ground adjacent the wall. The conduit in one aspect is a PVC tube mounted vertically against the wall and in aspects is embedded within the wall. The conduit allows for self-adjustment of the cable while also providing solid anchoring of the wall to prevent movement. The wall and system is lightweight, good looking and easy to install.

A modular building block apparatus for the construction of a coastal or river bank erosion defence or protection structure includes a plurality of blocks arranged in stacked rows, the blocks in each row having cooperating formations whereby the blocks in each row are interconnected with one another. Apertures formed in each block extend perpendicular to the rows, and a plurality of connector members extend through aligned apertures in adjacent rows of the blocks to interlock the rows to one another.

A hybrid permanent anchor is proposed. The hybrid permanent anchor includes: a fixed body disposed between a compression part and a tension part and coupling the compression part and the tension part to each other; the tension part coupled to a front end of the fixed body and transmitting tension to the permanent anchor when tensile stress is generated; the compression part coupled to a rear end of the fixed body and transmitting compressive force to the permanent anchor when compressive stress is generated; a PC steel strand coupled to a rear end of the compression part and having a protective pipe thereon; and an anchor head part fixing the permanent anchor to a structure.

A foundation for a structure pre-stressed via a plurality of tensioning members includes a foundation slab and a suspension device cast into the foundation slab. The suspension device includes an anchor element, which may be an upper anchor plate, located at least as high as an upper side of the foundation slab, the anchor element for attachment to one of the tensioning members. The suspension device also includes a lower anchor plate located at least as low as within a lower third of the foundation slab. The structure may be a container, a tower or a wind turbine tower. The structure may include a stack of prefabricated concrete parts. The disclosure is also directed to the combined structure and foundation, and to a method of manufacturing a structure having a foundation.

A grouting double-locking pressure real-time sensing system includes: a positioning structure fixed to a ground; wherein an expandable positioning structure passes through the positioning structure, and an input end of the expandable positioning structure is connected to the grouting structure; the pressure real-time monitoring component is connected to the expandable positioning structure; the expandable positioning structure comprises a hollow conduit, an expandable assembly, an upper positioning member, and a lower positioning member; wherein the upper positioning member and the lower positioning member are respectively connected to two ends of the expandable assembly; the hollow conduit passes through the upper positioning member and the lower positioning member, and is threaded to the the lower positioning member; the upper positioning member is fixed to the positioning structure; when rotating the hollow conduit, the lower positioning member moves up and down, so as to expand or contract the expandable assembly.
