Universal Pipe Rammer for Variable Diameter Trenchless Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current small model trenchless directional drilling machines require proprietary pipe stems, which are costly and limit their accessibility for short-distance horizontal drilling applications, necessitating the use of off-the-shelf, non-proprietary pipe stems that accommodate various diameters and materials.
Innovation Solution
A compact, lightweight horizontal trenchless pipe ramming device that uses off-the-shelf pipe stems, featuring a chassis with piston rods and a staging tray with modulating pipe saddles to accommodate different diameters, allowing for forward thrust and retrieval of pipes and cables without the need for proprietary components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary pipe stems are used in small model trenchless directional drilling machines, then the machine can achieve reliable drilling performance, but the cost increases and accessibility decreases
Solution Approach 1:
The device is designed with a universal engagement mechanism that can work with both proprietary and off-the-shelf pipe stems. The groove engagement system on the pipe outer circumference allows the device to accommodate different pipe types and diameters, making it versatile and accessible while maintaining reliable drilling performance through standardized engagement features
2Ease of operation
If proprietary pipe stems with specific dimensions are required, then the drilling machine can operate with precise control, but the device complexity and cost increase
Solution Approach 1:
The device incorporates adjustable components including variable stroke length capability and adjustable thrust force through hydraulic system control. The groove engagement mechanism can adapt to different pipe diameters dynamically, allowing precise drilling control without requiring complex proprietary pipe specifications or fixed-dimensional components

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables affordable, portable, and versatile short-distance horizontal drilling capable of handling various pipe diameters and materials, reducing costs and eliminating the need for proprietary equipment, thus making trenchless drilling more accessible to a broader range of users.
Implementation Method 1
The device comprises a hydraulic ram that engages the pipe stem and pushes the pipe stem forward into the ground
Implementation Method 2
a mechanism can be provided that engages the pipe outer circumference and pulls the pipe with it during the forward thrust motion
