urban jungle

Technicore Underground Inc. is a leader in the tunnelling industry, offering a wide array of solutions for city infrastructures and utility projects. One of the key services provided by Technicore is microtunneling – an effective and non-disruptive method for the installation of pipelines in urban environments. In this blog post, we aim to provide an in-depth exploration of microtunneling, discussing its significance and benefits, as well as shedding light on how Technicore effectively applies this technique in its projects.

Microtunneling is a trenchless construction method that is widely employed for installing pipelines beneath existing infrastructures, such as roads, railways, and buildings. This method involves the use of remotely controlled, laser-guided microtunneling machines that precisely excavate the ground while simultaneously installing pipelines.

The technique was developed as a response to the growing demand for an efficient and cost-effective means of creating underground infrastructure without causing surface damage and upheaval.

The adoption of microtunneling in pipelaying projects has gained immense traction in recent years, particularly due to its numerous benefits over traditional open-cut construction methods. Some of the key advantages include limited surface disruption and public inconvenience, reduced impact on roadways and traffic, and enhanced safety for workers.

Furthermore, microtunneling offers a more environmentally friendly solution, as it minimizes the release of greenhouse gas emissions associated with the demolition and reconstruction of above-ground structures.

Technicore’s experience and expertise in microtunneling make it an ideal choice for utility companies, municipalities, and other organizations seeking efficient, non-disruptive underground pipeline installations. By utilizing state-of-the-art microtunneling equipment and employing skilled professionals who are adept at minimizing risks and maximizing accuracy, Technicore ensures consistent success throughout every project.

In the forthcoming sections, we will delve deeper into the microtunneling process, discussing its applications, the various equipment involved, and how Technicore assures quality and safety while executing microtunneling projects. By understanding the intricacies of this innovative construction method, it becomes evident why microtunneling is the go-to solution for underground pipeline installations in modern urban environments. Stay tuned to gain valuable insights into the world of microtunneling and learn how Technicore continues to set the benchmark in the industry.

Microtunneling: Revolutionizing Urban Pipeline Installations

The Microtunneling Process: Precision and Efficiency in Action

The microtunneling process begins with establishing an entry and exit shaft. The entry shaft provides a location for the microtunneling machine to be launched, while the exit shaft serves as the retrieval site for the machine upon completion. Once the shafts have been constructed, the microtunneling machine, guided by a highly precise laser-guidance system, begins its underground journey from the entry shaft towards the exit shaft.

As the microtunneling machine excavates the soil, a pipe string is simultaneously installed behind it. The excavated soil is transported out of the tunnel using a slurry transport system, which mixes the soil with a liquid to create a slurry. The slurry then flows to the separators above ground, where excess soil is removed and the remaining fluid is recirculated back into the tunnel. This process significantly mitigates settlement risks and helps to balance pressure forces.

Throughout the microtunneling process, an operations team closely monitors the machine’s progress, making real-time adjustments to ensure proper alignment, grade accuracy, and to avoid any obstructions along the path. Upon completion, the microtunneling machine emerges at the exit shaft, leaving a perfectly aligned underground pipeline in its wake.

Applications of Microtunneling: Trenchless Solutions for Various Industries

Microtunneling has a wide range of applications, catering to multiple industries with diverse needs. Some of the most common uses of microtunneling include:

  • Water and Sewer Pipelines: Often used for potable water supply and wastewater collection, microtunneling ensures efficient utility servicing without interrupting surface infrastructure.
  • Stormwater Management: Microtunneling plays a critical role in implementing subsurface stormwater management systems, which help in reducing surface-level flooding risks.
  • Electrical and Communication Conduits: By utilizing this trenchless technology, cities and utility companies can deploy electrical and communication lines below the surface without disrupting above-ground infrastructure.
  • Pipeline Rehabilitation and Replacement: Microtunneling is an ideal solution when utility pipelines require rehabilitation or replacement in congested urban environments with minimal disruption.

Equipment and Machinery: The Driving Force Behind Microtunneling

A successful microtunneling project requires an array of specialized equipment designed to work in unison. Some key components of a microtunneling equipment setup include:

  • Microtunneling Boring Machine (MTBM): The MTBM is an advanced, remote-controlled excavation device equipped with cutting wheels and a laser-guidance system providing high accuracy excavation and pipe installation.
  • Slurry Transport System: This system comprises a slurry pump, separation plant, and recycling system, responsible for creating a continuous flow of slurry and removing spoil particles efficiently.
  • Jacking System: A powerful hydraulic jacking system is installed in the entry shaft, used to thrust the MTBM forward and support the pipeline installation process.
  • Control Container: A remote control-room houses the computer systems and monitoring devices required for operating the MTBM and analyzing real-time data.
