At <strong>Eurohinca<\/strong>experts in trenchless tunneling, use microtunneling techniques and remote-controlled tunnel boring machines to ensure efficient and accurate results. Below, we explore in detail the tunneling process, its technologies and key stages.<\/p><h2>History and evolution of tunnel construction<\/h2><p>Tunnel construction dates back thousands of years, but modern technology has transformed the process. From hand-dug tunnels in ancient times to today's methods of tunneling and tunneling.<a href=\"https:\/\/eurohinca.com\/en\/\" target=\"_blank\" rel=\"noopener\"><b> trenchless excavation<\/b><\/a>techniques have advanced to reduce environmental impact and improve safety.<\/p><h2>Excavation technologies used at Eurohinca<\/h2><p>Eurohinca specializes in excavation technologies <strong>trenchless<\/strong>This minimizes the impact on the surface and allows working in urban and sensitive areas. Some of the most outstanding technologies include:<\/p><ul><li><strong>Microtunnelers<\/strong>Used for small diameters, they allow precise excavation in urban areas and for sanitation projects.<\/li><li><strong>Remote-controlled tunnel boring machines<\/strong>Used in difficult terrain, these machines advance remotely controlled, optimizing safety and control.<\/li><\/ul><div>\u00a0<\/div><h3><span style=\"color: #00214e; font-size: 2rem; text-align: var(--text-align);\">Tunnel planning and design<\/span><\/h3><p>The tunnel construction process begins with detailed planning, including site survey and selection of the most suitable excavation method.<\/p><h3>Geological and geotechnical studies<\/h3><p>Geological and geotechnical studies are essential to evaluate the characteristics of the ground, as they determine whether the soil is hard rock, soft soil or a combination. <b>Eurohinca<\/b>The company, for example, conducts detailed preliminary studies to choose the right technology and ensure tunnel stability during construction.<\/p><h3>Selection of excavation technology<\/h3><p>Based on soil studies, engineers select the type of technology to be used. The choice between <strong>earth pressure tunnel boring machines<\/strong> y <strong>microtunneling<\/strong> depends on factors such as tunnel diameter, length and type of terrain. In large-scale projects, advanced systems such as the <strong>TBM (Tunnel Boring Machines)<\/strong>.<\/p><h2>Tunnel excavation and construction<\/h2><p>Tunnel excavation is one of the most critical stages and requires precision technology and expertise to ensure safe and efficient progress.<\/p><h3>Microtunneling<\/h3><p>Microtunneling is a popular technique in sanitation and drainage projects, especially in urban areas. It uses a microtunneling machine that excavates and places the tunnel lining at the same time. This method minimizes the risk of cave-ins and is highly efficient in soft ground.<\/p><h3>Advantages of Microtunneling:<\/h3><ul><li>Low impact on the surface.<\/li><li>High precision in complex terrain.<\/li><li>Ideal for urban areas.<\/li><\/ul><h3>Use of remote-controlled tunnel boring machines (TBMs)<\/h3><p>Remote-controlled tunnel boring machines allow controlled excavation from the surface. This system is especially useful in unstable terrain or where precision is required in tunnels of larger diameters. <strong>Eurohinca<\/strong> The technology is used in international projects such as the\u00a0<a href=\"https:\/\/eurohinca.com\/en\/voussoir-tunnel\/\" target=\"_blank\" rel=\"noopener\"><b>tunnel of voussoirs<\/b><\/a>\u00a0y<b>\u00a0<a href=\"https:\/\/eurohinca.com\/en\/submarine-emissaries\/\" target=\"_blank\" rel=\"noopener\">submarine emissaries<\/a><\/b>.<\/p><p>\u00a0<\/p><h2>Lining and safety in tunnel construction<\/h2><p>The lining is crucial to maintain the stability of the tunnel and protect it from water infiltration and other elements in the ground.<\/p><h3>Types of coatings<\/h3><p>The most common coating materials include:<\/p><ul><li><strong>Concrete segments<\/strong>Used in large diameter tunnels, they guarantee a high structural resistance.<\/li><li><strong>Steel panels<\/strong>Indicated for unstable soils or areas at risk of groundwater.<\/li><\/ul><h4>Monitoring and security systems<\/h4><p>During excavation and lining, monitoring systems are used to check the stability of the tunnel walls. Pressure sensors and high-resolution cameras help engineers identify potential problems before they become hazards.<\/p><h2>Eurohinca Projects<\/h2><p>Eurohinca has carried out numerous tunnel construction projects, both in Spain and in other countries.
