Jacket Pipe Connection With Depression For Ground Shift Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipe connections, especially in the mining sector, are technically complex and expensive due to the need for threaded connections, which are rigid and prone to damage from soil or rock material shifts, leading to potential buckling or destruction of the connection.
Innovation Solution
A pipe connection design featuring a spigot end with a conically tapering section and a depression on the socket end, allowing for flexible insertion and adaptation to soil or rock shifts, with symmetrical or asymmetrical U- or V-shaped depressions and predetermined bending points for secure and durable attachment, and a hydraulic pressing device for precise pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded connections are used to connect pipe ends, then the connection is rigid and secure, but the connection becomes technically complex and expensive due to threading requirements
Solution Approach 1:
The invention extracts the threading operation entirely from the connection process. Instead of cutting threads into pipe ends, the patent uses a simple insertion mechanism where a spigot end is inserted into a socket end with a stop feature, eliminating the need for complex threading equipment and operations while maintaining connection security
Solution Approach 2:
Instead of actively threading pipes together through rotational engagement, the invention inverts the approach by using a passive insertion method where the spigot end is simply pushed into the socket end until the stop prevents further insertion, creating a secure connection without any threading complexity
2Reliability
If threaded connections are used to connect pipe ends, then the connection is secure, but the connection is completely rigid and prone to damage from soil or rock material shifts
Solution Approach 1:
The invention introduces dynamic capability to the pipe connection by allowing relative movement between connected pipe sections. The stop feature prevents excessive insertion while permitting controlled movement, enabling the connection to adapt to ground shifts and rock material displacements without becoming damaged, thus transforming a rigid static connection into a dynamic adaptable one
3Stability of the object's composition
If rigid pipe connections are used, then the connection is stable, but the pipe connection can buckle or be destroyed when subjected to transverse or inclined stresses from soil or rock layers
Solution Approach 1:
The invention replaces the rigid static connection with a dynamic connection that can move and absorb stresses. The stop feature provides stability by preventing excessive movement while allowing controlled displacement, enabling the connection to withstand transverse and inclined stresses from soil or rock layers without buckling or destruction

Function Achieved in This Case
The solution enables quick, reliable, and adaptable pipe connections that can withstand soil or rock material displacements without damage, ensuring secure and load-resistant connections while simplifying the connection process and preventing material destruction.
Implementation Method 1
a pressing device for pressing the free end of the pipe section designed as a socket end by applying a pressing pressure, in particular a pressing pressure directed radially towards the interior of the pipe, into the depression of the pipe section of the other pipe designed as a spigot end

AI summary
In a pipe connection between a first pipe (1) and a second pipe (3), wherein one end section of the one pipe is designed as a pointed end (2) and is embraced by an end section (4) of the other pipe (3), which end section is in the form of a sleeve end, wherein the pointed end (2) has a reduced diameter in comparison to the pipe circumference, it is provided that a depression (5) which extends at least over a partial region of the circumference of the pointed end (2) is formed on that end region of the pointed end (2) which faces away from the pipe end.
