Retaining Wall Anchor Element with Integrated Geogrid Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of retaining walls with anchor elements is labor-intensive and requires skilled labor for assembling the bricks and connecting the anchor elements.
Innovation Solution
A gutter-shaped container with a lid is integrated into the anchor element, which houses a geogitter in a rolled or folded state, providing a secure and compact storage solution that reduces the risk of damage during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If geogrids are transported separately in a loose state, then they can be easily loaded and unloaded, but they are at high risk of damage during transportation and require significant manual labor for installation
Solution Approach 1:
The geogrid is nested inside the anchor element's storage chamber in a rolled-up or folded state. The container part forms a protective housing that contains the geogrid, allowing it to be transported in a compact, protected form without requiring separate handling or risking damage from loose transportation.
Solution Approach 2:
The geogrid is pre-assembled and stored within the anchor element before reaching the construction site. This preliminary assembly ensures the geogrid is already in its final configuration and protected, eliminating the need for manual unrolling and installation work at the construction site.
2Ease of operation
If geogrids are transported in a loose state, then loading and unloading is simple, but skilled labor is required for proper installation and connection to bricks
Solution Approach 1:
The anchor element merges multiple components into a single integrated unit: the container part for storage, the geogrid for soil reinforcement, and the connection interface for bricks. This combination allows the entire assembly to be installed as one unit, eliminating separate steps for geogrid handling and connection.
Solution Approach 2:
The anchor element is designed to be self-contained with the geogrid already positioned and protected within the container. The design enables workers to simply place the pre-assembled unit into position without requiring specialized skills for geogrid handling, unrolling, or connection procedures.
3Reliability
If the container part is designed to store the geogrid in a rolled-up state, then the geogrid is protected during transport, but the container part requires sufficient volume to accommodate the rolled geogrid
Solution Approach 1:
The geogrid is rolled into a cylindrical or curved form to fit within the container part. This curved configuration allows the flat geogrid material to be compacted into a small volume while remaining protected, efficiently utilizing the container's storage space.
