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.

A fixture for securing into a soil for bearing a load. The fixture comprises body having a foundation section for insertion into the soil. An anode surface and a cathode surface are provided on the foundation section and are electrically connected to one another. The anode surface comprises a metal or metal alloy with a more negative electrode potential than the cathode surface so as to promote electrochemical reactions within regions of the soil at or adjacent the interface between the fixture and the soil for causing a cementation processes to bond soil particles together and to the foundation section.

A retaining wall installation process for earth and water retaining wall, first step starting from preparing precast reinforced concrete heavy duty retaining wall (1) on the ground, inserted horizontal rebars (12) at each fin (7) passed to the holes (8), connected mechanical couplers (14) only one end of horizontal rebars. Attached shuttle-platform (16) to precast reinforced concrete heavy duty retaining wail (1). Then lift up to installed the wall at construction site, put down the vertical rebars (15) connected to the lower vertical rebars by using mechanical couplers (14), tie vertical rebars to horizontal rebars, then closed the vertical cavities (24) by using panel closer (28) and poured fresh concrete (29). After final setting time, removed shuttle-platform down to the ground.

The present disclosure relates to a foundation profile for an offshore structure. The foundation profile includes a profile end portion, which is arranged in an offshore subsoil in the intended state of the foundation profile. Further, at least one elongated hollow body is arranged at the profile end portion in the intended state. The elongated hollow body is configured to receive a swellable material.

A floating tunnel shore connecting system, a floating tunnel and a floating tunnel construction method are disclosed, where the design method of the floating tunnel is to apply axial tension along one end or two ends of a tube body respectively; The floating tunnel shore connecting system comprises a joint section located at the end of the tube body, which can move along the axial direction and is connected with a tension device for applying axial tension; The floating tunnel comprises a tube body and a hollow cavity, wherein the tube body comprises a floating section and a shore connecting system at two ends, and both joint sections are provided with tension devices. The design method and structure of the floating tunnel provided by the present invention, by applying the axial tension of the tube body, can significantly increase the horizontal stiffness and vertical stiffness of the whole floating tunnel tube body, improving the natural vibration frequency of the tube body, and the safety and reliability of the floating tunnel are improved; It is beneficial to the long-term use of the cable and the foundation anchored on the seabed or the riverbed. The construction risk is also lower, and the cost is also lower, which effectively saves the construction cost, and is easy to implement and popularize the project.

A method of forming a foundation (26) of a wind turbine (10) including a tower (12) having a base tower section (24), comprising: mounting a levelling apparatus (56) to an anchor cage (30), the anchor cage (30) including a plurality of anchor bolts (36) extending between an upper flange (34) and a lower flange (38), the levelling apparatus (56) being arranged between the upper and the lower flanges (34, 38); arranging the anchor cage (30) in an excavation pit (94); directing a cementitious material into the excavation pit (94) so that the upper flange (34) becomes at least partially embedded within the first cementitious material; allowing the cementitious material to cure to form a rigid body (28, 90); actuating the levelling apparatus (56) to raise the upper flange (34) from the rigid body (28, 90) into a levelled position; directing a grout material (32) into a space beneath the raised upper flange (34); and allowing the grout material (32) to cure to form a support layer. The invention extends to an anchor cage arrangement and a system for forming a wind turbine foundation.

The present invention is directed to a retaining wall system including a retaining wall having with at least one retaining wall rebar extending along a vertical direction, the at least one retaining wall rebar includes an end formed into a first retaining wall rebar hook, at least one deadman spaced from the retaining wall, each deadman including a concrete base extending along the vertical direction, the concrete base including rebar extending past the concrete base and having an end formed into a deadman rebar hook, at least a first hole at a top portion of the retaining wall and extending into the retaining wall to expose the retaining wall rebar hook, and a first cable attached to the retaining wall rebar hook and to the deadman rebar hook to support the retaining wall.

A budding element for coupling with other budding elements to erect a retaining wall. Exemplary building elements have receiving spaces for receiving increased weight of fill material to provide increased stability. Optionally, each building element can have an enlarged face profile that provides efficiency in the shipping and assembly process. Optionally, each building element can define alignment voids that receive portions of alignment posts for ensuring vertical alignment between adjacent building elements or portions of building elements.

A fiber sheet system suitable for controlling erosion and stabilizing soil is described that comprises a fiber sheet comprising a natural fiber felt. A coating composition comprising a natural rubber is adhered to the fiber sheet. The fiber sheet has a top side width less than the height and the length of the fiber sheet. A netting contacts the front and rear sides of the fiber sheet.

An expanding anchor and/or pile system wherein an outer shell of the pile/anchor is split lengthwise into at least two pieces and can be placed or driven into a hole in the earth in a retracted state and can subsequently be expanded such that the two or more pieces are forced outwardly—away from one another, thus causing them to exert a lateral force against the sides of the hole and thereby resulting in greater axial load carrying capacity in tension or compression of the anchor/pile.
