Thrust Boring Machines: The Ultimate Solution for Trenchless Excavation

Thrust boring machines, also known as underground boring machines or Ground Moles, are essential tools used in trenchless excavation for the installation of pipelines for gas, water pipes, communication and energy cables. They are designed to drill horizontal bores underground without disrupting the surface, making them a perfect solution for projects where there is limited space or where digging is not feasible.

How Thrust Boring Machines Work

Thrust boring machines are operated using a pneumatic drilling machine that works with pressured air at 6 bar. An air compressor is used to create the pressured air, which powers the machine to bore through the ground. The machine is moved forward and backward, creating a hole with a diameter ranging from 50mm to 232mm. The size of the diameter depends on the size of the machine being used.

The soil that is drilled is removed using a technique called Allame. Allame is a Turkish word that describes the removal of soil by means of a metal spoon or scoop. The soil is removed from the hole, allowing the machine to move forward and continue drilling.

The Benefits of Thrust Boring Machines

Thrust boring machines offer a wide range of benefits over traditional excavation methods. The main advantage is that they allow for the installation of pipelines and cables without disrupting the surface. This is particularly important in areas where the ground is already developed or where digging would be impractical or expensive.

Another benefit is that thrust boring machines are extremely accurate. They can bore through the ground with precision, making it possible to install pipelines and cables exactly where they are needed. This is important in areas where there are existing underground utilities that need to be avoided.

Thrust boring machines are also faster than traditional excavation methods. They can bore through the ground quickly, allowing for the installation of pipelines and cables in a fraction of the time it would take using traditional methods. This can result in significant cost savings for projects.

Thrust Boring Machine Sizes

Thrust boring machines come in a range of sizes, depending on the diameter of the hole that needs to be drilled. The most common sizes are:

• Diameter 50mm
• Diameter 75mm
• Diameter 97mm
• Diameter 132mm
• Diameter 160mm
• Diameter 190mm
• Diameter 232mm

Each size is designed to bore a hole of a specific diameter, making it possible to install pipelines and cables of different sizes.

Conclusion

Thrust boring machines are an essential tool for trenchless excavation. They allow for the installation of pipelines and cables without disrupting the surface, making them an ideal solution for projects where digging is not feasible. They are fast, accurate, and come in a range of sizes, making it possible to bore holes of different diameters. If you are looking for a reliable and cost-effective solution for your excavation needs, thrust boring machines are the way to go.
