Demolition Point Tree for Large Building Safety and Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for determining demolition points of large buildings face challenges in accurately estimating safety and efficiency, with current methods either prioritizing safety at the expense of efficiency or vice versa, and often requiring extensive structural analysis or posing environmental hazards.
Innovation Solution
A method involving the creation of a three-dimensional model of the building to analyze force conditions and generate a demolition point tree, which categorizes points into branch and leaf nodes, allowing for a structured demolition order that prioritizes safety and efficiency by first demolishing leaf nodes and subsequently branch nodes, with real-time updates during the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If area demolition method is used to improve demolition efficiency, then productivity increases, but safety estimation accuracy deteriorates
Solution Approach 1:
The building is divided into multiple grid areas, with each area containing multiple demolition points. This segmentation allows parallel demolition operations across different areas (improving productivity) while maintaining detailed safety analysis for each individual demolition point (preserving accuracy). The hierarchical structure enables independent evaluation of each segment's safety conditions.
Solution Approach 2:
The invention transitions from two-dimensional area-based demolition planning to three-dimensional point-based demolition planning. By establishing a 3D coordinate system and analyzing force conditions at specific points rather than across entire areas, the method achieves both high productivity (through parallel point-based operations) and high accuracy (through detailed point-level safety assessment).
2Reliability
If weak point demolition method is used to improve safety, then reliability increases, but productivity decreases
Solution Approach 1:
The building structure is segmented into multiple weak points identified through force condition analysis. Each weak point is evaluated independently for safety conditions, allowing parallel demolition operations at multiple safe points simultaneously. This maintains high reliability through rigorous safety checks while improving productivity through concurrent operations.
Solution Approach 2:
The system automatically identifies weak points and evaluates safety conditions through computational analysis of the 3D force model, eliminating the need for manual detailed structural analysis. This automated self-evaluation maintains high safety standards while significantly reducing preparation time and enabling faster demolition execution.
3Productivity
If dynamic demolition method is used to improve demolition efficiency, then productivity increases, but harmful factors increase
Solution Approach 1:
The invention performs preliminary identification and evaluation of all demolition points using 3D force model analysis before actual demolition begins. Safety conditions are assessed in advance, allowing careful planning of demolition sequences that minimize environmental impact while maintaining efficiency. This pre-planning eliminates the need for risky dynamic methods during execution.
Solution Approach 2:
The invention replaces dynamic mechanical demolition methods (blasting, pulling) with a statically planned, systematically executed demolition approach. By using computational mechanics to pre-determine optimal demolition points and sequences, the method achieves high efficiency through intelligent planning rather than through high-impact dynamic forces, thereby reducing environmental harm.
4Measurement precision
If simulated demolition method is used to improve safety estimation accuracy, then measurement precision increases, but productivity decreases
Solution Approach 1:
The invention creates a computational 3D force model that copies and represents the physical building's structural characteristics. This virtual model allows rapid safety analysis and demolition point identification without requiring time-consuming physical simulations or detailed manual structural investigations. The copied model enables both high accuracy assessment and quick decision-making for efficient demolition execution.
