Tunnel construction is a complex task that requires the application of various advanced techniques to ensure the stability and safety of the structure. At EUROHINCAWe are experts in a variety of specialized tunneling methods, each tailored to specific ground conditions and project needs. Below, we explore the main techniques we employ for tunnel construction, highlighting their characteristics and applications.
Pipe driving method
What is pipe ramming?
The pipe ramming is a technique used for the installation of pipelines without the need to excavate large trenches on the surface. This method consists of pushing a prefabricated pipe through the ground, using specialized machinery that applies pressure from an attack shaft. As the pipe advances, it displaces the soil around it, creating a tunnel in which it is installed.
At EUROHINCAThe pipe driving is performed by the application of hydraulic forces, which allows for a controlled and precise installation, ideal for projects in urban environments or areas where it is crucial to minimize surface disturbance.
Pipe jacking applications
Pipe jacking is especially useful in the installation of subway infrastructure such as drainage systems, drinking water and sewer lines. This method is suitable for crossing under roads, railways, and other infrastructure without disrupting traffic or surface activity.
Advantages of pipe ramming
This method offers several significant advantages, including reduced surface impact, the ability to work in congested areas, and minimizing the need for open excavation. In addition, pipe jacking allows for quick and efficient installation, with less risk of affecting existing infrastructure and less environmental impact.
Microtunneling method
What is the microtunneling machine?
The microtunneling machine is an advanced tunneling technique that uses a small diameter boring machine to excavate subway tunnels. This technique is ideal for projects that require the installation of pipes and pipelines in urban terrain, where space is limited and extreme precision is required.
During the microtunneling process, the microtunneling machine advances through the ground, excavating and removing material while the pipes or structures are simultaneously installed. This method is especially useful in the construction of small-diameter tunnels, such as those used for water, gas and other utilities.
Advantages of the microtunneling machine
The main advantage of the microtunneler is its ability to minimize surface disruptions, making it an ideal choice for projects in densely populated urban areas. In addition, its ability to work in confined spaces and its excavation precision make it ideal for projects where minimizing environmental impact is crucial.
Direct Pipe Method
What is Direct Pipe?
The method Direct Pipe is an innovative tunneling technique that combines the advantages of microtunneling and horizontal directional drilling (HDD). This method allows the installation of pipes and pipelines quickly and efficiently, without the need for additional excavations or the construction of attack shafts.
During the Direct Pipe process, a cutting head advances through the ground, removing material while the pipes are installed simultaneously. This method is ideal for infrastructure projects that require fast and accurate installation, such as crossings under bodies of water, roads and railways.
Direct Pipe Applications
The Direct Pipe method is widely used in large-scale infrastructure projects where minimizing environmental impact and installation efficiency are crucial. Its ability to combine excavation and installation in a single step makes it a preferred choice for tunneling projects in difficult terrain and urban areas.
