Abstract: The apparatus includes a shelf-like bracket which mounts to the exposed foundation of a building or other structure. The portion of the bracket which fits underneath the foundation is adjustable to permit secure fitting. The bracket includes a vertically mounted cylindrical member adapted for receiving and holding piers (pipes). A first housing is mounted vertically atop the bracket and is adapted to support a hydraulic cylinder for driving piers into the subsurface surrounding the foundation. Each pier is adequately secured to a preceding pier prior to being driven into the subsurface. Connected piers are consecutively driven into the subsurface to a predetermined point. The first housing is removed and a second driving device is used to drive the piers further into the subsurface. Grout is forced by pressure through the interior of the piers and out through the base pier's apertures, thereby forming a grout base at the base of the piers.

Abstract: A method and apparatus are used for reinforcing a wooden utility pole. A plurality of longitudinal braces are spaced circumferentially around the pole in a deteriorated area. The braces are connected together with links. The widths of the links increase in a downward direction so that the brace assembly will match the taper of the pole. After the brace assembly has been assembled, the assembly is moved downward on the pole to wedge it tightly against the pole.

Abstract: A method and apparatus for reinforcing the buried end of a wooden utility pole. The method uses elongate curved elements which are spaced about the periphery of the pole and driven into the ground so that their lower ends are buried. Bolts which pass through the pole are used to firmly clamp the members to the pole.

Abstract: A process for reinforcing and repairing utility poles and the like, including the steps of placing gasket layers above and below the area to be repaired and a resin pervious layer, such as fiberglass, between the two gaskets followed by the step of wrapping the area from the lower gasket to a point near the upper gasket with a resin impervious layer, such as duct tape. Next, a liquid resin is preferably injected under pressure into the space between the utility pole and the resin impervious layer. Holes may be drilled to guide the resin into the interior of the pole, and injection tubes may be inserted into the hole to further direct the resin into the interior of the pole. The resin is then allowed to cure. Preferably, vertical grooves are formed in the exterior of the pole, and reinforcing rods are placed therein before the resin is injected.

Abstract: This invention provides a method for repair for poles which have beem damaged by environmental effects, which is easily transportable, simple to install, and easily adaptable to many classes of poles. The method involves excavating around the pole, cleaning the surface of the pole, pumping a fumigant into the pole, applying a bonding agent to the clean surface, and then applying strips of a composite fiberglass mat and resin to the pole in a controlled manner until a desired casement thickness has been achieved. The repair is completed by application of an ultraviolet resistant coating to the pole.

Abstract: A seismic anchor has a head for location in a hole in ground-connected structure and a shaft connected thereto to extend out of the hole and mount members or equipment to be isolated from vibrations. The head is surrounded by vibration damping means, such as a high durometer rubber or rubber-like material. A covering extends along the shaft to the damping means. Solidified bonding agent in the hole, above the head and the vibration damping means, secures the anchor in place while the sleeve prevents the bonding agent hardening to the shaft and preventing relative vibration between the ground-connected structure and the shaft.

Abstract: An enclosure constituting a barrier for a buried segment of a pole to prevent leaching of pole preservatives into the ground. Pliable sheet material is formed into a tubular sheath by means of a lengthwise seam. A closure is formed at the lower end of the sheath by folding and a thermal weld. A band at the barrier upper end may be shrunk to close the barrier snugly about the pole.

Abstract: A method and apparatus for insitu reinforcement of a section of a wooden pole at a position below the groundline is disclosed. The method includes the steps of forming a cavity around the pole, mounting an elongated sleeve around the pole to define an annular space with the pole, and filling the space with a reinforcing material. The improved portion of the method includes supporting the sleeve above the groundline while mounting the same around the pole and securing the lower end against radial expansion, lowering the sleeve until it extends over the section to be reinforced, and filling the sleeve with a bonding agent, such as a foaming epoxy resin system, which bonds the sleeve to the pole over the length of the section to be reinforced. Preferably the upper end of the sleeve is contracted and sealed against the pole.

Abstract: A new and improved utility pole reinforcement system includes an elongated pole splint driven into the ground adjacent the pole and having contact surfaces adapted to engage and support the surface thereof. The splint includes a structural body spaced outwardly of the pole providing increased resistance to stress applied to the pole. A pair of brackets are spaced apart longitudinally on the body portion of the splint, each bracket having opposite end portions extending laterally outwardly and a tension strap assembly for binding the pole and splint together is connected to opposite end portions of each bracket. Each strap assembly includes at least one elongated strap of relatively thin flexible material conforming generally to the surface of the pole and formed with a plurality of longitudinally spaced apart apertures.

Abstract: A method and kit for repairing in situ a utility pole, especially a wooden one, when damaged at around ground level uses a sleeve to surround a substantial length of the pole and a non-shrink hardenable pourable composition to occupy a clearance between the sleeve and the pole and form a solid core bonded to both of them, so as to yield a very strong assembly. Preferably the sleeve is of two identical parts clipped together round the pole, and the composition is a magnesium phosphate cement.

Abstract: A utility pole support (42) for repairing or strengthening a damaged or broken utility pole (2) including a first part (44) which is securely fastened to the pole above ground level in use and a second part (46) which is so shaped to be driven into the ground against the surface of the pole under the ground in use to provide support around the weakened part (10) of the pole, the support being retained in place below ground level by the action of the earth against the pole support.

Abstract: A soil excavating and utility pole securing sleeve is disclosed which will, when rotated around a standing utility pole, excavate an annulus of soil between the pole and the interior of the sleeve. The excavating sleeve defines an elongated hollow cylinder having teeth and inwardly bent excavating doors or flaps at one end which moves the soil between the utility pole and the sleeve out the door or flap and compacts the soil into the earth surrounding the sleeve. The sleeve is rotated into the ground around the utility pole for half its length, left there, and the evacuated annulus of soil then filled with a mixture of epoxy, resin, fungicide, and aggregate, allowed to cure and harden in order that the utility pole, the filling, and the sleeve become one single structure with a strength greater than that possessed by the original utility pole when new.

Abstract: A ground anchor for channel posts has an angle iron leg driven into the ground and an upright fin plate or strip secured to the upper end thereof to stabilize the leg against tilting. The channel post straddles the angle iron leg receiving the apex of the leg in the channel thereof and is deformed to spread its legs apart into tight gripping relation with the angle iron. The spreading apart of the legs may be effected by drawbolts which fixedly connect the channel post with the angle iron leg or by a tool applied to the post adjacent the leg permitting the post to enter a socket on the leg formed by the fin plate or strip whereupon releasing of the tool permits the spread apart post legs to spring back toward their free state position thereby bottoming the base of the post in the socket. The spread apart legs of the post tightly grip the angle iron leg. The post may be removed from the angle by releasing the drawbolts or by again applying a spreading tool to free the post from the socket.

Abstract: A bracket (90) fixedly supports a structural member (120) with respect to an aperture (128). The bracket (90) has a semicircular cross section body (100) with one end portion (94) for placement on the structural member. A second end portion (96) extends into aperture (128). The bracket body (100) has a plurality of longitudinally extending corrugations (92) along the body. A wedge shaped driving member (98) extends outward from the body (100) and extends between the first and second body portions (94) and (96). A clamp (130) and/or screws (188) fasten the first bracket body portion (94) to the structural member (120) or (180). In use, the bracket (90) is driven into the aperture (128) by striking the driving member (98). The driving member (98) and the corrugations (92) coact with the aperture (128) to provide a camming action, which expands the bracket body end (96) in at least one dimension to hold the bracket (90) tightly in the aperture (128).

Abstract: A hanger for supporting pipes below steel reinforced concrete slab foundations provides an elongated bendable shaft which can be connected to the reinforcing steel of a formed slab foundation prior to the pouring of the concrete. An open loop is secured integrally to the bottom portion of the shaft at a point of beginning, the loop having a curved generally circular body of less than three hundred sixty (360.degree.) degrees which terminates at the point of beginning and at a loop-free end. A radial strut extends from the loop-free end and away from the circular loop along a radial line originating at the loop center. Manual pressure applied to the bottom portion of the shaft and to the radial strut can close the loop by aligning the strut and shaft together in side by side relation. The loop can be closed permanently by a closure ring which can slide upon the aligned portion of the radial strut and elongated shaft so that the loop can be retained in a closed position.

Abstract: An assembly (10) for supporting a post (12) with respect to an aperture (14) in concrete (16) includes first and second opposed surfaces (32). Each of the surfaces (32) has one end shaped to fixedly engage an end of the post (12). Each of the surfaces (32) has a second end extending longitudinally beyond the end of the post (12). The extending ends of the surfaces (32) are configured to enter the aperture (14) and have opposed camming shapes (38 and 44) which wedge the extending ends of surfaces (32) into tight engagement with the aperture (14) as the extending ends move further into the aperture (14). The method includes providing such an assembly, driving the assembly to position one end of the surfaces (32) against the post (12) and the extending end into aperture (14), so that the camming surfaces (38 and 44) push the extending end of the surfaces (32) against the aperture (14). The surfaces (32) are then fixedly attached to opposing sides (24 and 26) of the post (12) by screws (22).

Abstract: A tubular drain vertically positioned within the ground beneath the ground level in the vicinity of surface water and having a tubular drain cover-support member anchored in the surface ground layer with a tubular part of the drain cover-support means extending down into the tubular drain, so as to be axially movable relative thereto as a separately movable support element in annular disc form placed around the tubular part of the drain cover-support member so as to be axially movable relative to the drain while being guided by the upper part with it being anchored in the surrounding ground layer in a manner so as to be able to exert a downwardly pressing force from the underlying drain when relative movement is obtained between the drain and the supporting element.

Abstract: A method and apparatus for permanently extending the height of an upright pole set in the ground uses pole reinforcers which are driven in the ground alongside and complemental to the pole. Extensible power devices mounted on ground-engaging supports use gripping heads mounted adjacent the upper end of the device, in such manner that actuation of the devices holds the heads in biting engagement with the pole. As the devices are extended, the heads pull the pole from the ground and through the predetermined channel formed by the pole reinforcers. Once the pole is extended to the desired elevation, the pole reinforcers are permanently secured to the pole to provide stability at the new height. The present invention is useful in moving the pole through extended displacements in a single stroke of the hydraulic cylinders of the devices, obviating the necessity for successive attachment and detachment of the apparatus during raising of the pole.

Abstract: A ground heating system comprises a porous stabilization layer provided between a pipe system for supplying heat and a pipe system for supplying water to control the ground humidity. The stabilization layer functions as a water distributor and heat storage means.

Abstract: A bracket for offset anchoring a fence post comprising a vertical leg member, a horizontal leg member, a post attachment means, and a means for anchoring the bracket to a new concrete foundation.

Abstract: A tubular plastic shell, with an overlapped longitudinal seam and longitudinally extending interior pockets that form exterior ribs, encircles a wooden pole or piling in an area to be protected. A foamed adhesive between the shell and pole fills and seals the surface of the pole beneath the shell, adheres the shell, and provides a supporting cushion for the shell that inhibits cracking or puncturing from impact. Longitudinally spaced ends of the shell beyond the pockets tightly encircle the pole to prevent escape of the adhesive as it forms during application. Ribs at the overlapped seam nest into pockets to retain the shell tightly about the pole during expansion of the adhesive. Where impact or abrasion are not anticipated, the shell can be used as a carrier and mold for forming an adherent foamed sealant layer or covering about a pole and then be removed.
