Multi-Mold Slip Forming for Concrete Structure Refinement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The slip forming process for concrete structures is often messy, unpredictable, and requires significant manual labor for adjustments and repairs, leading to inconsistencies and increased project costs due to the need for additional touch-ups and the challenges of blending concrete from different batches.
Innovation Solution
A system utilizing multiple slip form molds, where a first mold forms the initial structure and a second mold, equipped with a vibration device, modifies and refines the structure by advancing along the path and delivering concrete, reducing the need for manual labor and blending different batches of concrete to achieve uniformity and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single slip form machine is used to form concrete structures, then the initial structure can be formed efficiently, but the process produces inconsistencies requiring significant manual labor for touch-ups and repairs
Solution Approach 1:
The system divides the slip forming process into two distinct stages using two separate machines: a lead machine that forms the initial structure and a follow machine that refines and modifies it. This segmentation allows each machine to specialize in its function, with the follow machine correcting inconsistencies left by the lead machine, thereby maintaining high productivity while improving manufacturing precision.
Solution Approach 2:
The lead machine performs preliminary forming action first, creating the basic structure. Then the follow machine performs secondary action to refine and correct the structure. This preliminary action approach allows the system to maintain high forming speed while ensuring quality through subsequent refinement passes.
2Adaptability or versatility
If additional functionality is added to slip form machines, then more features can be supported, but the process remains messy and unpredictable with natural inconsistencies
Solution Approach 1:
The follow machine acts as a feedback mechanism that continuously monitors and corrects inconsistencies in the structure formed by the lead machine. By having the second machine refine the work of the first, the system creates a self-correcting process that reduces unpredictability and maintains reliability even as versatility increases.
Solution Approach 2:
The system changes the operational parameters between the two machines: the lead machine operates with parameters optimized for speed and volume, while the follow machine operates with parameters optimized for precision and refinement. This parameter differentiation allows the system to achieve both versatility and predictability.
3Manufacturing precision
If manual touch-up and repair work is performed to correct inconsistencies, then structure quality can be improved, but labor costs and project time increase
Solution Approach 1:
The system makes the slip forming process self-correcting by having the follow machine automatically refine and repair inconsistencies as it travels behind the lead machine. This eliminates the need for separate manual touch-up operations, improving structure quality while avoiding additional time losses.
Solution Approach 2:
The follow machine performs refinement and repair actions continuously as it travels along the structure, rather than requiring stopping and separate manual operations. This continuous action maintains productivity while ensuring quality corrections are made promptly.
4Manufacturing precision
If concrete from different batches is used to make up for deficiencies, then structural deficiencies can be addressed, but visual defects and blending challenges arise
Solution Approach 1:
The follow machine applies concrete and modifications only in the specific local areas where deficiencies are detected, rather than uniformly treating the entire structure. This localized approach allows for structural repairs while minimizing visual defects and blending issues, as corrections are made only where needed.

Function Achieved in This Case
This approach significantly reduces manual labor, minimizes visual defects, and ensures a cleaner, more structurally sound finish by seamlessly blending concrete from different sources, enhancing the quality and consistency of the final concrete structure.
Implementation Method 1
The second hopper can include a vibration device. The vibrator can be configured to promote a fluid consistency of the liquid concrete and/or compaction of the liquid concrete within the mold.

AI summary
A method of slip forming a concrete structure can include using a first slip form mold that travels along a path to form a portion of a concrete structure by delivering a first flow of concrete into the first mold through a first hopper. The first hopper can be configured to receive the first flow of concrete. The portion of the concrete structure can be modified using a second slip form mold different from the first mold by advancing the second mold along the concrete structure and, while advancing the second mold, delivering a second flow of concrete into the second mold through a second hopper that is configured to receive the second flow of concrete.
