Concrete Pile Cutting Assembly with Segmented Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing concrete pile cutting devices are complex, cumbersome, and costly, requiring support equipment like cranes or excavators, and often necessitate user proximity to the cutting site, making them inefficient and difficult to use.
Innovation Solution
A concrete pile cutting assembly featuring a collar with interconnected collar elements that securely engage the pile and mount a cutting saw, allowing the saw to cut the pile without the need for additional support equipment, enabling the user to operate from a safe distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If complex support equipment like cranes or excavators is used to mount cutting devices, then the cutting capability is achieved, but the device complexity and operational cost increase significantly
Solution Approach 1:
The collar is divided into multiple separate collar elements that can be assembled around the pile shaft independently, then connected together to form a complete circular structure. This segmentation allows the device to be transported and assembled without requiring heavy support equipment, while still providing sufficient structural integrity for cutting operations.
Solution Approach 2:
The collar elements are designed to be self-supporting when assembled around the pile shaft, eliminating the need for external cranes or excavators to provide structural support. The locking rods and locking inserts create a self-contained structure that maintains its shape and position during operation.
2Ease of operation
If the user must be in close proximity to the cutting site for operation, then direct control is possible, but safety risks and operational difficulty increase
Solution Approach 1:
The collar elements act as an intermediary structure between the user and the cutting operation. By providing a rigid, self-supporting framework that can be assembled at a distance from the cutting zone, the system allows users to operate from safer positions without requiring direct proximity to the active cutting area.
3Ease of manufacture
If traditional cutting devices are used, then cutting function is provided, but the operational cost and complexity increase
Solution Approach 1:
The collar elements are designed as simple, inexpensive components that can be manufactured from standard materials and assembled using basic tools. Rather than requiring expensive, complex support equipment, the system uses multiple simple elements that provide adequate functionality for the cutting operation.

AI summary
A concrete pile cutting assembly configured for cutting a concrete pile includes a cutting saw portion supported on a collar portion. The collar portion securely engages the concrete pile and mounts the cutting saw portion adjacent the concrete pile at a desired height such that a cutting blade of the cutting saw portion cuts, or severs, the concrete pile at the desired height. The collar portion includes a plurality of collar elements each having a beam, a connecting flange, and a locking fastener. The locking fastener of a first beam engages with a corresponding beam opening of a second beam to connect adjacent collar elements together. Each beam has at least one mounting cylinder and the cutting saw portion includes a post for engaging with one of the mounting cylinders provided on the beams to mount the cutting saw portion onto the collar portion.
