Drain Pipe Arrangement Settlement Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drain line arrangements in buildings are prone to separation due to settlement differences between the building and surrounding subsoil, leading to improper drainage and potential damage, requiring frequent inspections and costly excavation to rectify.
Innovation Solution
A drain line arrangement featuring a control rod anchored to the horizontal drain pipe, with a long sleeve connection between the vertical and horizontal pipes, allowing for easy monitoring of settlement movements and maintaining a secure fluid connection through a telescopic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid pipe connection is used between the vertical supply line and horizontal drain pipe, then the connection is stable and secure, but the pipe connection will separate due to settlement differences between the building and subsoil
Solution Approach 1:
The pipe connection transitions from a rigid static structure to a dynamic telescopic system that can adapt to settlement movements. The inner pipe can move axially within the outer pipe, allowing the connection to dynamically adjust to differential settlement between the building foundation and surrounding subsoil while maintaining fluid tightness.
Solution Approach 2:
The connection geometry changes from fixed to variable through telescopic movement. The overlapping length between inner and outer pipes can vary to accommodate settlement, and sealing elements change their position and compression state to maintain sealing under varying geometric conditions.
2Reliability
If frequent inspections are conducted to detect pipe separation, then problems can be identified early, but inspection effort and excavation work increase significantly
Solution Approach 1:
The control rod provides continuous visual feedback about the telescopic connection status. By monitoring the position of the control rod relative to the inner pipe, settlement movements and potential connection issues can be detected without excavation, replacing frequent physical inspections with simple visual checks.
Solution Approach 2:
The control rod acts as an intermediary indicator that translates the internal telescopic connection status into an externally visible signal. This mediator allows remote monitoring of the connection state without direct access to the buried pipes, eliminating the need for frequent excavation-based inspections.
3Adaptability or versatility
If a telescopic long sleeve connection is used to compensate for settlement, then pipe separation is prevented, but the complexity of the connection increases
Solution Approach 1:
The telescopic connection is segmented into an inner pipe and an outer pipe that can move independently relative to each other. This segmentation allows each component to perform its specific function while simplifying the overall design compared to a monolithic complex mechanism.
Solution Approach 2:
Sealing elements and control rods act as intermediaries that enable the telescopic function without requiring complex mechanical joints or fastening systems. The sealing elements provide both sealing and positioning functions, while the control rod provides both structural support and visual indication.
