Conduit Spacer Assembly With Flow Passages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conduit spacer systems are difficult to maneuver during manual installation, tend to buckle or twist, and obstruct the flow of fill material, increasing installation time and reducing protection and insulation effectiveness.
Innovation Solution
A conduit spacer assembly with a conveyance assembly that moves along a track secured to the outer conduit, allowing for easy alignment and insertion of inner conduits while facilitating unobstructed flow of fill material through flow passages in the spacers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If bore spacers are manually inserted and conduits are manually inserted through holes in the spacers, then the conduits can be spaced apart within the casing, but the spacers tend to buckle or twist during insertion, increasing installation time and requiring remedial action
Solution Approach 1:
The conduit spacer assembly is pre-assembled with conduits already positioned through the spacer holes before insertion into the casing. This preliminary assembly ensures proper spacing alignment is achieved before the actual installation, preventing buckling and twisting during the insertion process while maintaining manufacturing precision.
2Manufacturing precision
If bore spacers are used to secure and space conduits within the casing, then conduit spacing is achieved, but the spacers obstruct the flow of fill material such as cement between the conduits, resulting in areas with little or no support or insulation
Solution Approach 1:
The spacer design incorporates localized flow passages or openings in strategic positions that allow fill material to pass through the spacer structure. This maintains the spacing control function while creating local pathways that eliminate the harmful obstruction effect, ensuring uniform distribution of fill material for adequate support and insulation throughout all areas.
3Reliability
If multiple conduits are secured together and collectively installed in a single outermost casing, then protection from digging is achieved, but the installation process becomes more complex and time-consuming
Solution Approach 1:
Multiple conduits are merged with the spacer and conveyance assembly into a single integrated unit that can be installed together as one collective assembly. This merging approach maintains the protective benefit of having conduits secured together in a casing while simplifying the installation process by reducing the number of separate installation operations required.

AI summary
A conduit spacer assembly for supporting and conveying an inner conduit into an outer conduit. The conduit spacer assembly has one or more conveyance assemblies moveable along a track coupled to the outer conduit. One or more conduit spacers are suspended from the conveyance assemblies, and support the inner conduit. The conveyance assemblies may be coupled together by a strap member. A force applied to one conveyance assembly is transferred to the other conveyance assemblies via the strap member. An installation assembly having a frame structure and a track support assist with the installation of the conduit spacer assembly and the inner conduit.
