Advantages of horizontal directional drilling at infrastructure crossings

The horizontal directional drilling (PHD) has become an essential technique for subway crossings in infrastructure projects. This method allows pipes, cables and conduits to be installed under roads, rivers and railways without significantly altering the surface, offering modern and efficient solutions. In the following, we will explore its main advantages and its most outstanding applications.

What is horizontal directional drilling?

Horizontal directional drilling is a subway construction method that, using advanced equipment, digs precise tunnels without the need for trenching. The process consists of three phases: pilot drilling to lay out the route, enlargement of the tunnel and insertion of the necessary conduits, such as pipes or cables.

Advantages of horizontal directional drilling

Reduction of environmental impact

The PHD allows crossing sensitive terrain, such as rivers or protected urban areas, without causing visible alterations to the environment. This makes it the most sustainable option for projects in protected areas or under bodies of water. For example, in projects highlighted by the International Society for Trenchless Technology (ISTT)The effectiveness of these products in the conservation of the environment is emphasized.

Reduced surface disruption

Unlike traditional excavation, PHD does not require trenching, which significantly reduces disruption to residents and traffic in urban areas. This benefit is critical for jobs in densely populated environments, where maintaining daily activity is a priority.

3. Time and cost efficiency

Although the initial cost may seem high, PHD speeds up execution times by eliminating excavation and site restoration processes. This is especially useful in civil workswhere tight deadlines are a constant.

4. Versatility in difficult terrain

Whether in clayey, rocky or water-saturated soils, horizontal directional drilling can be adapted to different geological conditions. In addition, this technique makes it possible to avoid subway obstacles, such as existing pipelines, which makes it ideal for complex urban projects.

5. Precision and advanced control

Thanks to the use of advanced navigation and sensor technology, operators can accurately control the drilling path. This ensures accurate results even in large-scale projects, such as submarine emissariesone of the outstanding applications of the horizontal directional drilling.

Practical applications of PHD

Horizontal directional drilling has a wide range of applications, including:

Piping installationFor potable water, gas and sewage systems.
Telecommunications and electricityCable crossings in urban or rural environments.
Underwater crossingsUnder rivers, lakes or protected marine areas.
Urban infrastructuresWhere open excavations are not feasible.
