Drilled-and-Grouted Caisson with Cutter Head Anchor
The foundational architectural primitive of the Anchor Tension System. Establishes the drilled-and-grouted caisson foundation and cutter head anchor at foundation depth, with a thrust bearing arrangement at the caisson-to-cutter-head interface that transmits the tubular tension column's pre-load into the underlying ground.
Conventional pole and tower foundations rely on large concrete pads or massive concrete footings sized to resist lateral loading and overturning moment from conductor tensions, conductor wind loading, and tower self-weight. Each foundation is project-engineered and site-poured. Continental-scale corridor deployment cumulatively consumes vast concrete volume in foundations alone, and each foundation is constructed in place by traditional construction methods that do not scale efficiently along the corridor.
Conventional foundation engineering also pairs the foundation to the structure above it as an inseparable unit. If the structure above must be replaced, modified, or upgraded, the foundation work is typically duplicated. There is no standard architectural primitive that decouples the foundation from the structure it supports while still transmitting the structural loads cleanly into the ground.
The Foundation Core establishes a drilled-and-grouted caisson foundation as the deep-foundation primitive on which all subsequent MMC structures are deployed. The caisson is drilled to engineered depth using purpose-built drilling equipment, the cutter head is left in place at foundation depth, and the caisson is grouted to bond the foundation system into the underlying ground.
The architectural innovation is the integration of a thrust bearing arrangement at the caisson-to-cutter-head interface. The thrust bearing transmits the tubular tension column's pre-load into the cutter head, which in turn transmits the load into the underlying ground through the engineered caisson interface. This decouples the structural loading path from the foundation construction methodology — the same caisson primitive serves any structural application above it, from low-voltage distribution poles to ultra-high-voltage transmission towers to multi-modal viaduct corridors.
The drawing below illustrates the architectural primitives covered by this patent. Engineering specification and full claim language are available to qualified parties on direct request.
A drilling rig (per the Foundation Drilling System patent) drills the caisson to engineered depth. The cutter head, used during drilling, remains in place at foundation depth and becomes the anchor termination for the structural tubular column installed in subsequent ATS construction phases. The caisson is grouted to bond the foundation to the surrounding ground. A thrust bearing arrangement at the caisson-to-cutter-head interface accommodates the structural load path, transmitting the pre-load from the tubular tension column into the cutter head and into the underlying ground.
The caisson dimensions, depth, and engineering parameters are configured per project deployment. Distribution-pole-scale deployments use small-diameter shallow caissons. Transmission-tower-scale deployments use larger-diameter deeper caissons. Continental multi-modal viaduct deployments use the largest caissons engineered to the loading at each pylon location along the corridor. The architectural primitive is the same in every case — only the dimensions vary.
