Soil Consolidation Roll With Segmented Windings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil consolidation and stabilization nets are difficult to control during installation, especially for long tracts, and there is a need for a cost-effective solution with high mechanical strength.
Innovation Solution
A roll with a reticular structure comprising intersecting first and second elements forming meshes, wrapped around a winding axis, with a marker to differentiate initial and end windings for easier installation and control, made from materials like polypropylene, polylactic acid, or their mixtures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the net is wrapped around a cylinder to make a roll for easy storage and transport, then storage and transport convenience is improved, but the net becomes difficult to control during installation, especially for long tracts
Solution Approach 1:
The roll is divided into multiple windings with different functions: initial windings (with markers for easy identification and control during installation), intermediate windings, and end windings. This segmentation allows the net to maintain roll form for storage while enabling better installation control through the differentiated initial windings with markers.
Solution Approach 2:
The initial windings are pre-marked with markers before installation. This preliminary action allows installers to easily identify the starting point and control the unwinding process during installation, solving the control difficulty without changing the roll storage form.
2Strength
If the net is made with high mechanical strength for soil consolidation, then consolidation effectiveness is improved, but the manufacturing cost increases
Solution Approach 1:
The net structure uses elements with different characteristics in different locations: initial windings include markers for control, while all windings use cost-effective materials like polypropylene or polylactic acid that provide sufficient mechanical strength for soil consolidation without requiring expensive materials throughout the entire structure.
Solution Approach 2:
The net uses inexpensive materials such as polypropylene, polylactic acid, or their mixtures that provide adequate mechanical strength for the intended application. These materials are cost-effective and suitable for the temporary function of soil consolidation during vegetation establishment.
3Length of moving object
If the roll contains a large number of windings for long tract installation, then installation coverage is improved, but the ratio of initial windings with markers becomes very small, reducing their effectiveness
Solution Approach 1:
Instead of increasing the number of marked windings along the length, the solution places markers on the initial windings at the dimensional starting point of the roll. This allows even rolls with hundreds of windings (e.g., 200-800 windings) to have effective markers at the critical installation start point, maintaining marker effectiveness regardless of total winding count.

AI summary
A roll (1) for soil consolidation or stabilization including a reticular structure having: first elements (3) spaced from each other and having an elongated conformation according to a first trajectory (T1), second elements (4) spaced from each other and having an elongated conformation according to a second trajectory (T2) transverse to the first trajectory (T1), the first and second elements (3, 4) intersect at nodes (5) to form meshes (6), wherein the reticular structure (2) is wrapped around a winding axis (X) to define windings grouped as: a first group of initial windings defined between a first inner winding (21) of the reticular structure and to an intermediate winding, and a second group of end windings defined between a final outer winding (23) of the reticular structure (2) and the intermediate winding.
