Protective Structure With Deadman Anchors for Cable Load Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective structures require costly and labor-intensive drilling into the subsoil for ground/rock anchors or posts, especially in difficult terrain, which is inefficient and expensive.
Innovation Solution
A protective structure using deadman anchorages for support cables that do not require drilling, achieved by excavating a pit and inserting a cable shaft with a deadman anchor, which is then buried with material to absorb tensile loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If ground anchors or posts are used to fix support cables, then the protective structure can withstand tensile loads, but drilling into the subsoil is required which is costly and labor-intensive
Solution Approach 1:
The invention extracts the support cable fixation from the ground/rock anchors or posts that require drilling, and replaces it with deadman anchorages that can be installed without drilling operations. This removes the problematic drilling step while maintaining the load-bearing function.
Solution Approach 2:
The deadman anchorages are designed as simpler, less expensive alternatives to drilled ground anchors. They can be installed using basic excavation and backfilling operations rather than requiring specialized drilling equipment and procedures.
2Strength
If ground anchors or posts are used to fix support cables, then the protective structure can withstand tensile loads, but the installation process becomes time-consuming and expensive
Solution Approach 1:
The invention removes the time-consuming drilling operation from the installation process by replacing ground anchors with deadman anchorages that are installed through simple excavation and backfilling, dramatically improving installation speed and productivity.
Solution Approach 2:
The deadman anchorages utilize the surrounding soil or rock material itself to provide anchoring resistance, eliminating the need for specialized drilling equipment and complex installation procedures, thereby accelerating the installation process.
3Ease of manufacture
If deadman anchorages are used instead of ground anchors, then installation costs are reduced and installation is simplified, but the ability to withstand large tensile loads must be maintained
Solution Approach 1:
The deadman anchorages are designed with sufficient mass and dimensional proportions to counterbalance the tensile loads applied to the support cables. The anchorages act as counterweights that resist the pulling forces through their weight and the friction/interlocking with the surrounding material.
Solution Approach 2:
The inventiveness lies in changing the parameters of the anchorage system - using larger mass and different geometric proportions in the deadman anchorages compared to traditional ground anchors. This allows the same load-bearing function to be achieved through different physical parameters that are easier to install.

Function Achieved in This Case
Enables efficient tensile load dissipation without additional equipment, reducing installation costs and simplifying the installation process by using deadman anchors that can withstand large loads.
Implementation Method 1
pulling the deadman anchor through the soil material
Implementation Method 2
The deadman anchorage is designed to dissipate the tensile load applied to the support cable by pulling the deadman anchor through the surrounding material
