Definitions

  • the utility poles are used to support wires for both power and telecommunication.
  • the wooden structural piles support all types of structures including buildings, foundations, RR trusses, bridges, piers, marinas, docks and wharfs.
  • Most of these poles and piles have been pressure treated with some type of preservative, such as creosote, penta, or CCA. As the preservative depletes over time, the poles/piles become susceptible to biotic degradation caused by moisture, fungi, and insect activity.
  • a vacuum/tremie manifold is configured for communication with a vacuum source.
  • a plurality of vacuum/tremie ports are in communication with the vacuum/tremie manifold.
  • the plurality of vacuum/tremie ports are disposed in a spaced apart relation within the cylindrical sidewall and are oriented to evacuate a back fill material from the ground surface surrounding the support pole to define a void.
  • the annulus excavation tool is formed with a plurality of segments.
  • Each segment includes a portion of each of the cylindrical sidewall, the jetting manifold, the vacuum/tremie manifold; the plurality of fluid jets, and the plurality of vacuum/tremie ports.
  • a fastener may join each of the plurality of segments.
  • the method includes evacuating the dislodged backfill material by a vacuum source applied to a plurality of vacuum/tremie ports.
  • the vacuum/tremie ports are disposed in a spaced apart relation about the annulus excavation tool.
  • the method includes applying a sonotube or a temporary steel form, around the support pole.
  • the sonotube extends a desired vertical distance above the ground surface.
  • the liquid mortar mixture may then be poured into the sonotube.
  • the sonotube may be filled with the liquid mortar mixture to the desired vertical distance.
  • a system for servicing a support pole installation includes an annulus excavation tool having a plurality of jets oriented to direct a pressurized fluid source to dislodge a backfill material retaining the support pole in a ground surface.
  • a plurality of vacuum/tremie ports selectively evacuate the dislodged backfill material to define a void around the support pole and communicate a liquid mortar to fill the void.
  • a reservoir containing a volume of the fluid and a pressure delivery pump in communication with the reservoir are also provided.
  • a suction pump selectively communicates with the plurality of vacuum/tremie ports and a soil decant is provided to contain a quantity of the evacuated backfill material.
  • a materials container is configured to communicate a predetermined quantity of a dry mortar mix to the mixing unit.
  • a collection manifold may be formed of 1 .5” plastic pipe at the top of the annulus tool 40 on each half section and high-pressure hoses 18 connected to each of the manifolds (fig 5). The hoses will join in a ⁇ ” connection and go to the pump 22.
  • an encasing annulus 52 of fiber reinforced grout 52 is poured around the once decayed area 12 and at least 0.5 feet above and below the decayed area 12.
  • the mortar mix 52 fills the void in the area evacuated by the annulus tool 40 suctioning as well as the voids in the support pole 12 that are introduced with the removal of the decayed wood 12 from the support pole 10.
  • the 2” mortar annulus 16 may be precast in a factory on the new wood pole and the composite structure installed in a larger hole.

Abstract

Dans la présente invention, un outil d'excavation annulaire entoure le poteau ou le pieu dégradé et excave hydrauliquement l'espace annulaire autour du poteau jusqu'à 2,0 pieds par l'intermédiaire d'un collecteur par injection. Un collecteur à vide/trémie est sélectivement couplé à une source de vide pour retirer le sol et le matériau dégradé et créer une surface de liaison pour le mortier. L'outil annulaire est ensuite couplé à la source de mortier et soulevé pendant qu'un mortier d'UHPC est tremié dans l'outil pour une distribution dans l'espace annulaire. Lorsque l'outil atteint le niveau de sol, le reste de la coulée est réalisé à l'aide d'un tube Sonoco ou d'une autre forme temporaire. Cette enveloppe de mortier ne comble pas seulement les déficiences structurelles mais isole également le poteau de l'air et de l'eau qui tue ensuite les champignons et les insectes existants tout en empêchant également toute invasion ultérieure.
