What Are Bundled Bore Solutions? A Better Way to Install Multiple Lines in One Bore
Installing multiple pipelines or utility lines beneath a roadway can create significant construction challenges.
Depending on the project, contractors may need to install several lines across the same road, highway, or other obstacle.
One option is to construct separate bores for each line.
Another is to bundle multiple lines together and install them through a common bore.
However, bundled installations introduce an important challenge: How do you keep the individual pipes separated and protected during installation?
This is the problem that Bundled Bore Solutions (BBS) was developed to address.
What Is a Bundled Road Bore?
A bundled road bore is an installation method in which multiple pipes or utility lines are grouped together and installed through a common underground crossing.
Instead of creating a separate bore for every line, the contractor may be able to install multiple lines through one appropriately designed bore.
This approach can be useful for projects involving multiple pipelines, conduits, or utility services traveling along the same route.
However, the feasibility of bundling depends on the pipe dimensions, installation method, bore geometry, and project requirements.
What Is Bundled Bore Solutions?
Bundled Bore Solutions (BBS) is a pipe separation system designed to help maintain spacing between individual lines installed together in a bundled bore.
Developed by Joint Specialists Inc., BBS uses purpose-designed components to help prevent direct contact between the individual pipes in a bundle.
The system provides a practical alternative to relying on improvised pipe separation methods.
Why Is Pipe Separation Important?
When several pipes are installed together, they may experience movement and contact during handling and installation.
Without appropriate separation, one pipe may rub against another.
This can create several concerns.
Coating Damage
Pipelines with external corrosion protection coatings may be vulnerable to mechanical damage from direct pipe-to-pipe contact.
Abrasion
Movement between adjacent pipes can create friction and abrasion during installation.
Bundle Organization
Maintaining consistent spacing helps contractors assemble and manage the bundle before installation.
Installation Planning
A defined pipe spacing arrangement can help contractors evaluate the overall bundle dimensions and installation requirements.
How Does BBS Work?
BBS uses specially designed bumper or spacer components positioned to maintain separation between the individual pipes.
The components help create a controlled arrangement rather than allowing the pipes to rest directly against one another.
The appropriate configuration depends on the number of lines, pipe diameters, coating systems, and installation requirements.
BBS has been used in bundled installations involving multiple lines, with configurations tailored to project needs.
What Are the Potential Advantages of Bundling Multiple Lines?
When engineering and construction conditions permit, a bundled bore may offer advantages compared with constructing several separate crossings.
Potential benefits include:
Fewer individual bore operations
Reduced repeated setup requirements
Consolidated utility crossings
Simplified routing where multiple lines follow the same path
Better organization of multiple lines during installation
These benefits are project-dependent. Bore size, pulling forces, equipment capabilities, and site conditions must still be evaluated.
Who Uses Bundled Bore Systems?
BBS may be relevant to:
Pipeline contractors installing multiple lines across roads or other obstacles.
Utility contractors working with multiple conduits or services.
Directional drilling and boring contractors evaluating multi-line crossings.
Engineers and project planners designing bundled pipeline or utility installations.
What Information Is Needed for a Bundled Bore?
Before selecting a spacing system, contractors should identify:
Number of lines being bundled
Outside diameter of each line
Pipe coating or jacket type
Desired spacing between lines
Bore dimensions and installation method
Length of the crossing
Project-specific installation requirements
These details help determine whether a bundled installation is practical and what spacer configuration may be appropriate.
