20080279635SIDE LOADING CONDUIT SPACER - Apparatuses and methods are disclosed for mounting conduits within spacers for underground installation. Spacers for side loading of conduit, as opposed to older methods of end loading, allow construction workers to easily assemble conduits to a plurality of spacers above-ground. The side loading technique uses spacers having bores that communicate with each other, preferably in a radial manner. Thus, a first plurality of conduits may be assembled or mounted to an inner portion of the spacers and then at least a second plurality of conduits may be assembled and mounted to an outer portion of the spacers. Cables later pulled through the conduits are typically those used for the transmission of electricity or communication signals. Other embodiments use bores that do not communicate with each other but are secured to the spacers with an outer banding saddle.11-13-2008
20130129424Method of constructing concrete pipelines of large diameter in an area of laying, a device for the method - A method of producing a concrete pipeline in an area where the pipeline is to be laid has the steps of making a trench, installing in the trench a cylindrical elastic element with a diameter equal to an inner diameter of the pipeline to be laid' placing armature on the cylindrical elastic element, pouring a liquid concrete solution on the element with the armature and hardening the concrete solution, after the hardening of the concrete solution turning a part of the element inside out, placing a reinforcing on a thusly obtained portion of the element with turned part, pouring a concrete solution again onto the portion of the element with the armature.05-23-2013
20090148239Resilient protection of through-foundation pipes - A resiliently-mounted through-foundation pipe coupling is provided that is suited for building plumbing applications. The resiliently-mounted coupling assembly is a length of straight plastic pipe preferably with pipe couplings on each end. The combined length of the pipe and associated couplings is selected to roughly match the thickness of the foundation. The combined pipe and associated couplings are covered with and bonded to a relatively thick layer of foam rubber elastomeric material. The combination of pipe and elastomeric layer is placed in the desired position in a foundation form before the foundation is poured. The elastomeric layer cushions the plastic pipe from the forces of being cast in place as the foundation is poured, and also provides resilience to the eventually installed piping system (connected to the through-foundation pipe fitting) against the motion of back-filled soil, and against alignment forces and mechanical loading of attached plumbing.06-11-2009

20100014921SYSTEM AND METHOD FOR FACILITATING UNDERGROUND COMMUNICATION CABLE INSTALLATION UTILIZING SOIL EROSION TECHNIQUES - A technique for aiding an underground communications cable installer in the installation such cable in underground utilities neighborhoods. The technique manages the problem presented by a surface-visible, underground-pathway obstruction such as a sidewalk, which lies across the path of installation. The technique, or method, is useful with any kind of cable, such as fiberoptic cable or copper wire cable. Hydraulic water pressure is applied through a biased, flexible conduit to erode a pathway under the obstruction from ground surface on one side to ground surface on the opposite side of the obstruction, thereby forming a tunnel under the obstruction through which the cable can be easily pulled. In alternative embodiments, the cable can be inserted directly into and through the conduit while it is underground, the conduit then acting as a sleeve for the cable which is subsequently removed prior to burying the cable in a trench dug from street-located handhole to house. Special apparatus connects a water hose to the flexible conduit (PVC plastic) to provide watertight operation while allowing manual flow control.01-21-2010
