Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming underground barrier walls are time-consuming, prone to structural inconsistencies, and difficult to reinforce with sensors, as they require extensive concrete pouring and reinforcement, making it challenging to create uniform and sensor-accessible structures.
Innovation Solution
A modular barrier wall system comprising interlocking wall segments with length and width coupling subassemblies, reinforced with inner braces and communication structures, allowing for efficient assembly and sensor integration within a trench, enabling simultaneous trench formation and wall construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional concrete pouring method is used to form barrier walls, then the wall structure can be formed, but the construction process is very time consuming
Solution Approach 1:
The barrier wall is divided into multiple pre-cast concrete segments that can be manufactured separately and then assembled in the trench. Each segment is formed with coupling subassemblies that enable rapid connection, eliminating the need for time-consuming on-site concrete pouring and curing while maintaining structural integrity through precision-engineered joint interfaces.
Solution Approach 2:
The concrete segments are pre-formed off-site with all reinforcement, sensors, and coupling mechanisms already in place before delivery to the construction site. This preliminary preparation of segments includes pre-embedding communication structures and sensors, so that no additional time is needed for on-site reinforcement installation or sensor embedding during wall assembly.
2Reliability
If traditional concrete pouring method is used, then the wall can be formed, but it is difficult to know the exact structure of the trench as portions may collapse
Solution Approach 1:
By using pre-fabricated segments with standardized dimensions and coupling mechanisms, the wall structure achieves uniformity regardless of trench conditions. Each segment maintains its precise geometry from factory production, and the coupling subassemblies ensure consistent joint geometry, eliminating variations caused by trench wall collapse or settlement that would affect cast-in-place concrete.
Solution Approach 2:
The pre-cast segments are designed with built-in structural reinforcement and coupling mechanisms that compensate for potential trench instability. The rigid, pre-formed segments maintain their structural integrity even when placed in trenches with varying stability, and the coupling subassemblies accommodate minor misalignments without compromising wall uniformity.
3Reliability
If traditional concrete pouring method is used, then the wall can be formed, but sensors become encased within hardened concrete making it impossible to replace or insert new sensors
Solution Approach 1:
Sensors are not permanently encased within the concrete segments but are instead extracted to external mounting positions on the segment surfaces or within accessible channels. Communication structures extend through the segments to provide external access points, allowing sensors to be removed, replaced, or upgraded without breaking the concrete structure or requiring excavation of the wall.
Solution Approach 2:
The segments are designed with universal communication structures and sensor mounting interfaces that can accommodate different sensor types and configurations. This multi-functional design allows the same segment structure to support various sensing applications while maintaining easy access for sensor maintenance and replacement through standardized external interfaces.
4Strength
If traditional concrete pouring method is used, then the wall can be formed, but reinforcement rods and forms must be inserted into slurry which is difficult and time consuming
Solution Approach 1:
All reinforcement requirements are satisfied within each pre-cast segment during factory manufacturing, where reinforcement rods can be easily installed in controlled conditions. The segments are delivered to site as complete, reinforced units, eliminating the need for on-site reinforcement installation into wet concrete or slurry, which is difficult and time-consuming.
Solution Approach 2:
Reinforcement structures are pre-installed in each concrete segment before the concrete hardens, during the controlled factory casting process. This preliminary reinforcement installation ensures proper positioning and bonding without the difficulties of working with wet concrete on-site, and the pre-formed segments arrive at the construction site with complete reinforcement already in place.
