Landfill Membrane Capping Assembly With Ground-Anchor Tethering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current capping systems for landfill sites face challenges in securely sealing and stabilizing covering membranes, often relying on heavy materials like sandbags and tires, which can be cumbersome and inefficient, and existing solutions do not effectively utilize tethering systems to anchor caps to the ground.
Innovation Solution
A capping assembly comprising a cap with a securing arrangement and an insertion member that allows for secure attachment to the covering membrane, using a tethering assembly with a ground anchor and gripping device to ensure stability and sealing, allowing for efficient clamping and sealing of the membrane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy materials like sandbags and tires are used to weigh down the covering, then the covering is secured on the landfill, but the system becomes cumbersome and inefficient
Solution Approach 1:
The patent extracts the heavy materials (sandbags and tires) from the system and replaces them with a tethering assembly that uses ground anchors and wire ropes to secure the cap. This removes the cumbersome weighting components while maintaining the securing function through a different mechanism.
Solution Approach 2:
The patent introduces a tethering assembly as an intermediary component between the cap and the ground. This assembly includes a ground anchor driven into the ground, wire ropes connected to the cap, and a gripping device that secures the rope to the anchor, providing an efficient mediation for securing the covering without heavy materials.
2Reliability
If existing capping systems are used, then the covering is secured, but the tethering systems are not effectively utilized to anchor caps to the ground
Solution Approach 1:
The patent applies preliminary action by driving the ground anchor into the ground before attaching the wire rope and cap assembly. This pre-installation of the anchor provides a ready-made securing point that simplifies the subsequent attachment process and improves overall installation efficiency.
Solution Approach 2:
The patent segments the securing system into distinct functional components: the ground anchor driven into the ground, the wire rope for tensioning, the gripping device for securing the rope, and the cap assembly. This segmentation allows each component to be optimized independently and facilitates easier manufacturing and installation.
3Reliability
If adhesive is used to attach the cap to the covering, then the cap is secured to the covering, but additional materials and complex installation are required
Solution Approach 1:
The patent extracts the adhesive material from the attachment system and replaces it with a mechanical clamping mechanism. The cap includes a clamping assembly with a clamping member that mechanically secures the covering membrane between the cap and the insertion member, eliminating the need for adhesive substances.
Solution Approach 2:
The patent replaces the chemical bonding mechanism (adhesive) with a mechanical fastening system. The clamping assembly uses mechanical force through the clamping member to secure the covering, providing a more efficient and material-free attachment method.
