A land anchor is disclosed for pulling an immobilized vehicle out of the mud or snow. The land anchor includes a pull bar which is reversibly connectable or linkable to a bucket by passing the pull bar through a slot in the bucket. The bucket portion of the anchor includes a blade which can be driven into the ground and then removed from the ground once the vehicle has been freed. A connecting end of the pull bar engages the bucket and prevents the pull bar from passing completely through the slot, and can include lateral wings for added strength. The land anchor can be positioned, anchored, and operated by a single person with assistance from a winch and cable assembly to move the immobilized vehicle to a solid area of ground.

A method of installing one or more anchors in an underwater substrate in a body of water including installing an anchor into the underwater substrate by rotating an anchor installation vehicle about a central axis Y to drive the anchor coupled to the anchor installation vehicle into the underwater substrate. The anchor installation vehicle includes a vehicle frame having a top end and bottom end, a plurality of arms extending outward from the vehicle frame, one or more rotational thrusters disposed at distal ends of the respective arms, and an anchor system that holds the anchor extending from the bottom end of the vehicle frame with the anchor aligned with a central axis Y.

A basalt fiber anchoring system with accurate sectioned grouting includes: a plurality of first base plates arranged in an anchoring borehole, where every two first base plates are arranged at an upper end and a lower end of a section to be grouted respectively; a plurality of basalt fiber reinforced plastics (BFRP) penetrating the plurality of first base plates; and a grouting device including a valve pipe and a grouting core pipe, where the valve pipe penetrates all the first base plates, a plurality of grouting ports are defined in a pipe wall of the valve pipe, each of the plurality of grouting ports is covered with an elastic sheath, the grouting core pipe is sleeved with two grout stop sealing plugs at intervals, a plurality of grout outlets are provided between the two grout stop sealing plugs.

An integrated anchoring structure of basalt fiber reinforced plastic (BFRP) bars for a reservoir bank slope includes: a plurality of BFRP anchoring bars, where each of the BFRP anchoring bars includes a plurality of BFRP bars bonded to one another, a lower steel casing pipe, an upper steel casing pipe and a steel strand bonded to an upper portion of the upper steel casing pipe and aligned with the BFRP bars, and a grating array temperature sensing optical cable, a grating array stress sensing optical cable and a grating array vibration sensing optical cable are bonded in each of the BFRP bars; a plurality of shear-resistant bricks distributed on structural planes; a pouring base arranged at a bottom of the anchoring borehole; and an anchoring section arranged at an upper portion of the pouring base.

A ladder anchoring system utilizing a ground anchoring device and a series of strap assemblies to secure the ladder in position and hold the ladder tightly against both the ground surface and the associated structure to prevent tipping or falling. Further, the ladder anchor system of the present disclosure is quickly and easily installed and/or adjusted to allow for ease of manufacturing, assembly, and/or use thereof.

An alignment and installation jig for a screw anchor driving machine. The alignment and installation jig includes a laser target that can be moved from an alignment position to a driving position. The jig may also include one or more automated crimping assemblies to form permanent connections between overlapping foundation components while the machine is correctly oriented to assembly a truss foundation. One crimping assembly device may effect crimp joints between a foundation component held by the jig and overlapping upper ends of a pair of adjacent foundation legs. Second crimping assemblies may telescope down each leg to effect respective crimp joints between the lower end of the leg and the upper end of a driven foundation component.

A construction method of fast-setting polymer grouting for rapid control of slope erosion and landslide. This solution includes a landslide control method and a slope erosion control method: sorting out an operation platform; drilling and grouting of polymer high-pressure jet grouting piles on the diseased slope; drilling a row of grouting water interception holes densely on the rear edge of the diseased slope; drilling, on the operation platform, a plurality of anchor holes on the diseased slope; inserting a ground anchor into each anchor hole and performing polymer grouting to form a polymer anchorage body; laying a steel wire gauze on the surface of the diseased slope, and connecting and fixing the steel wire gauze with the tail end of each ground anchor; spraying a two-component expandable polymer grouting material onto the steel wire gauze to form a polymer anti-scour layer; drilling a plurality of planting holes on the diseased slope with a backpack drill through meshes of the steel wire gauze; and filling each planting hole with grass seed mixed nutrient soil. The present invention has the advantages of short construction period, ecological and environmental protection, convenient construction, high strength and strong scour resistance.

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.
