Ground Anchor Reinforcement With Expandable Slats for Immediate Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anchoring systems require cement mortar or resin to embed anchor rods in the ground, which is time-consuming and impractical in restricted spaces, and do not allow immediate load transfer.
Innovation Solution
A set of anchor reinforcement comprising a rod with load transfer elements and a tubular element with a pointed end, allowing pressure or impact insertion without soil entry, and slats that expand radially for immediate anchoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If cement mortar or resin is used to embed anchor rods in the ground, then anchoring strength is improved, but installation time increases and immediate load transfer is not possible
Solution Approach 1:
The invention extracts and eliminates the binder (cement mortar or resin) from the anchoring system, replacing it with a purely mechanical anchoring mechanism using expandable elements that transfer load through friction and mechanical interlocking, thereby enabling immediate load transfer without waiting for binder maturation
Solution Approach 2:
The invention replaces the chemical bonding mechanism (binder maturation) with a mechanical anchoring mechanism using expandable elements that create immediate mechanical interlocking with the surrounding ground, allowing load transfer to begin immediately upon installation
2Strength
If cement mortar is introduced for anchoring, then load transfer capability is improved, but the process becomes impractical in restricted spaces
Solution Approach 1:
The invention removes the binder material (cement mortar) from the anchoring process, eliminating the need for mixing, transporting, and injecting materials into restricted spaces, and replacing it with a mechanical expansion system that can be installed using only the anchor rod itself
Solution Approach 2:
The anchor rod performs its own installation function through the expandable elements that self-expand upon insertion, eliminating the need for external binder materials and the complex equipment required to deliver and place them in restricted spaces
3Reliability
If traditional anchoring systems are used, then anchoring is achieved, but aesthetic appearance is compromised by external distribution plates
Solution Approach 1:
The invention nests the distribution function within the anchor rod itself through internal expandable elements, eliminating the need for external distribution plates and achieving a clean, aesthetic appearance while maintaining full anchoring functionality within the ground
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables immediate load transfer and increased anchoring efficiency without binders, suitable for urgent interventions and restricted spaces, with enhanced mechanical anchoring and aesthetic benefits.
Implementation Method 1
a pointed end that is situated in front of the rod in its insertion direction into the ground and has a diameter greater than the diameter of the tubular element, the pointed end being able to favour the advancement of the anchor reinforcement in its pressure or impact insertion, as well as to prevent the introduction of soil into the tubular element
Implementation Method 2
at least one load transfer element that is fixed to the rod and able to transfer the load into the ground
Implementation Method 3
slats that expand radially for immediate anchoring
