Segmented Manhole Assembly for Compact Transport and Fast Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monolithic manholes are inefficient for storage and transportation due to their large size, requiring significant space and incurring high transportation costs, and they lack efficient assembly methods on-site.
Innovation Solution
The manhole assembly is composed of interconnected longitudinal and ring segments with features like dowel pins, dowel holes, clip bosses, hinges, and gaskets, allowing for compact storage and easy assembly on-site, with options for connection via clips, hinge pins, living hinges, and welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If monolithic manhole design is used, then durability is improved, but storage and transportation efficiency deteriorates
Solution Approach 1:
The manhole is divided into multiple longitudinal segments that can be separately manufactured and transported. Each segment contains connection features (dowel pins, dowel holes, clip bosses) that enable assembly into a complete manhole structure, resolving the contradiction between durability and storage efficiency.
2Reliability
If monolithic manhole design is used, then durability is improved, but transportation cost increases
Solution Approach 1:
By segmenting the manhole into multiple transportable pieces, the invention reduces the volume and weight that must be transported for each individual component, thereby lowering transportation costs while maintaining the durability of the assembled structure.
3Ease of operation
If monolithic manhole design is used, then ease of installation is improved, but storage efficiency deteriorates
Solution Approach 1:
The manhole is segmented into modular sections with standardized connection features, allowing efficient stacking during storage while enabling straightforward assembly on-site through the connection of pre-fabricated segments.
4Volume of moving object
If segmented manhole design is used, then storage efficiency is improved, but assembly complexity increases
Solution Approach 1:
The segmentation is designed with standardized connection features (dowel pins, dowel holes, clip bosses) that simplify the assembly process. The modular design allows segments to be easily connected using straightforward mechanical fastening methods, reducing overall assembly complexity despite the segmented structure.
