A fence dispensing apparatus for installing fencing wire along a line of fence posts. The fence dispensing apparatus permits easy setup along with efficient and safe operation. In addition to dispensing wire, the apparatus stretches unrolled wire using a winch and a wire interface. The fence dispensing apparatus essentially comprises a base member that sits on an axle and wheels. Moreover, the base member connects to a motor vehicle via a hitch receiver or a three-point tractor hookup. As the vehicle travels along a fence line, the apparatus dispenses wire from a vertically aligned spindle and/or from a horizontally aligned roller. The spindle disconnects from the base member, permitting it to be easily loaded with wire and set up for operation. Additionally, a spindle lock and spindle support act in concert to safely hold the loaded spindle in position. Furthermore, a wear plate between the loaded spindle and the base member protects the base member from excessive wear during operation. In addition to the spindle, a horizontally aligned roller dispenses wire. The horizontal roller includes a safety plate that protects against injury if the unrolled wire breaks and backlashes. Unrolled wire may be connected to a wire interface, permitting the unrolled wire to be associated to a cable without cutting the wire. Turning the apparatus' winch reels in the cable, stretching the unrolled wire.

The invention relates to a machining method and equipment for steel bar keels. The machining method includes the steps that a plurality of steel reinforced cages which are shaped like pillars overall are arranged in parallel and then connected into a whole; then the steel reinforced cages connected into a whole are cut into steel bar keels matched with prefabricated wall body modules in shape; or the steel reinforced cages connected into a whole are cut and then reassembled and connected into steel bar keels matched with the prefabricated wall body modules in shape. The machining method and equipment for steel bar keels have the beneficial effects that sheet-shaped steel bar nets are obtained through a net welding machine and then bent to obtain the cylindrical steel reinforced cages; continuous steel reinforced cages can be rapidly machined by connecting upper weft steel bars and lower weft steel bars through the cylindrical steel reinforced cages and then cut into needed steel bar keels or cut and then reconnected into steel bar keels. The machining method and equipment for steel bar keels resolve the bottleneck problem of low machining efficiency of steel bar keels in the process of prefabricating of the wall body modules. Feeding is carried out through a steel bar coil sold in the market, then finished steel bar keel products can be rapidly machined through a set of equipment, and wide application of the prefabricated wall body modules is facilitated.

A planter assembly o raise a garden bed to a height that eliminates or minimizes stoop labour is comprised of lightweight, flexible, materials with adequate tensile strength as well as a rigid element with adequate compressive strength.

Flexible wire mesh is formed into a perimeter frame of pre-determined width, length and height in combination with rods and wire.

A textile lines the perimeter frame, providing a barrier impervious to soil. The textile encloses the top horizontal wire of the mesh within a hem held fast by wire and is thereby restrained. A band of the textile, sufficiently wide to be held to the ground by the placement of soil, extends from the base of the perimeter frame towards its middle.

Wire is also used as crossties to enable the lateral earth pressure pushing against one side to resist the lateral earth pressure pushing against the side opposite.

A chain link woven mesh comprises successive undulated transverse links (1,2,3,4), which are interconnected together at the bent portions of the links, whereby each pair of successive undulated links (1,2), (3,4) forms a row of adjacent rectangular or square meshes (5) with four sides. At least at one border of the mesh, for each pair of successive links, the last side of the first link (1) is bent upwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the second link (2). The last side of the second link (2) is bent downwardly and backwardly over a sharp angle, whereby the end of this last side is hooked around the penultimate (last but one) side of the first link (1). The advantage is that a very strong border is obtained.
