Abstract:
A composite pile structure is formed from a lower wooden section and a tubular metal section connected to the wooden member and filled with concrete. The wooden section is first started into the ground a desired distance, and the metal section is then supported on the upper end of the wooden member. A mandrel member is located in driving engagement with the upper end of the metal section and the lower end of the mandrel is supported in spaced relation to the wooden member. Initial hammer energy of limited intensity is applied to drive the metal section into the wooden member until the bottom of the mandrel comes into contact with the top of the wooden member. Thereafter, hammer energy of greater intensity is applied to the connected sections and concentrated against the surface area of the wooden member enclosed by the imbedded metal section. The pile driving operation is rapidly carried on, and splitting of the wooden member is avoided by applying the hammer energy in the manner described.
Abstract:
Parts present in the soil above the groundwater table are protected from attack by micro-organisms, termites and other oxygen-consuming organisms by injecting a hydrocarbon compound around the threatened parts into the soil, which compound is oxidized by micro-organisms present in the soil.
Abstract:
A post sleeve provides a substantially permanent base for supporting a post for a fence or sign, and from which one post can be removed and replaced with another post. The sleeve includes a concrete body that is poured on site, using a sleeve core prepositioned in the post hole, and around which wet concrete is poured. After the concrete is cured, the core is removed, leaving a post sleeve cavity configured to receive a post. The core can be rigid, or can include a flexible shell and stiffener. A preformed post sleeve top can be attached to the sleeve core and positioned therewith in the post hole, to become a permanent part of the post sleeve, once the concrete cures. A drain is attached to the core, and remains in the sleeve when the core is removed, and can be a percolation chamber, or passage extending below the sleeve.
Abstract:
An apparatus for consolidating earth and anchor setting device. The apparatus includes a vertical support, a plurality of spaced media consolidation plates swingably mounted to the vertical support, a rib disposed along a lower edge of respective ones of the consolidation plates and a bearing plate secured to the vertical support. The apparatus can be used to install a bearing and moment foundation having an upper surface, a lower surface and a converging side surface. The upper surface is adapted to receive a pushing force for pushing the foundation into the soil and the side surface adapted to contact the soil when a pushing force is applied to the upper surface. The anchoring device can also be used to install a pier foundation having a plug, an installation load bearing member, an installed load bearing member and a cap. A grillage assembly can be used to install the foundation and includes at least a pair of intermediate members forming a grillage, at least one anchor securing the grillage to the soil and a plate member secured to the grillage intermediate members and positioned above the soil surface to assist in at least one of installing a foundation, removing an anchor, testing the strength of an anchor and testing the strength of a foundation. Also disclosed are methods of installing an anchor and a foundation.
Abstract:
A support having a timber pile. The support has a sheath positioned about the pile and in spaced relation to the pile to define a gap between the sheath and the pile. The support has a cured polymer disposed between the sheath and the pile and permeated into the pile. A method for reinforcing a structure. A method for building a support for a structure.
Abstract:
Splicing means for connecting two wood piles, end-to-end, to make a long pile for transfer of pile-loads to lower, stronger ground. The splicer comprises: at least one plate-like, substantially horizontal element adapted to lie between adjacent pile ends, with optional epoxy glue between upper and lower surfaces of this element and the upper and lower piles; and a central upright dowel member, extending above and below the plate-like element. This plate-like element is in the form of a disk in FIGS. 1 to 3 and 6 to 9; in FIGS. 4 and 5 there are two plate-like elements (the horizontal parts of angle irons, these irons being welded on opposite sides of the dowel); and in FIGS. 10 and 11, the plate-like element has two parts that are at angles to each other and integrally joined at their lower lines of junction (this angle plate being fixed to a V-shaped cut in the lower pile). Preferably, the splicer comprises other pile penetrating and anchoring elements that are fixed to the platelike element, for example: the piece of six-inch pipe of FIGS. 1 to 7, extending around the disk (or angle irons of FIG. 4), driven into the upper and lower piles; the vertically-extending parts of the angle irons of FIGS. 4 and 5; the prongs of FIGS. 6 and 7, struck-out from the disk; the laterally placed, doublepoint pins of FIGS. 8 and 9; or the hammer-driven nails or spikes of FIGS. 10 and 11. And preferably the upper pile section of the composite pile is within a tightly clamped metal band, and is at least 30 feet long.
Abstract:
A TIMBER PILING CONSTRUCTION INCLUDING AN UPRIGHT TIMBER PILE AND A CONCRETE SLAB SUPPORTED ON THE UPPER END OF THE PILE. A PAIR OF CONNECTOR PLATES ARE RIGIDLY SECURED ON OPPOSITE SIDES OF THE PILE, THE CONNECTOR PLATES ARE IN THE SHAPE OF AN ANGLE WITH ONE LEG HAVING A PLURALITY OF NAIL HOLES FOR RECEIVING NAILS DRIVEN INTO THE WOOD PILE. THE OTHER LEG OF THE CONNECTOR PROJECTS OUTWARDLY AT THE UPPER END OF THE PILE. CONCRETE IS CAST OVER THE CONNECTOR AND THE UPPER END OF THE PILE TO FORM A UNITARY STRUCTURE.

Abstract:
A method for installing a composite timber and concrete piling system provides metallic tube that is partially filled with concrete. The unfilled portion of the metallic tube defines a splice member when the metallic tube is driven into a timber pile. The timber pile member is first driven into the earth at a selective position and at a selective orientation but a partial distance which leaves a small portion of the timber pile exposed above ground. The metallic tube is then placed on top of and aligned with the axis of the timber pile. The unfilled portion of the metallic tube forms a splice. The concrete filled metallic tube is forced downwardly until the unfilled portion of the tube is embedded into the exposed portion of the timber pile and wherein the concrete in the tube approaches the top of the timber pile. During driving, the concrete in the tube contacts the top of the timber pile.
