A guided pipe jacking system is a trenchless technology that enables the installation of underground utilities—such as water pipelines, sewer pipes, energy lines, electricity, telecommunications, fiber optic cables, water or sewage conduits—without extensive excavation work. The jacking machine is hydraulically driven and equipped with a steering head, allowing the drive path to be corrected as necessary. Thanks to measurement systems, the operator monitors the depth and alignment of the drive path, ensuring high precision even over lengths of several dozen meters. This is essential when accuracy is required and for accurately navigating around obstacles in the ground, to avoid damaging or interfering with existing infrastructure. This solution is particularly valued in locations where excavations are difficult or impossible—for example, beneath roads, lawns, rail tracks, parking lots, walkways, or developed areas. Why does it pay to use guided pipe jacking? Guided pipe jacking offers an alternative to traditional excavation work by eliminating the need to break open the surface. This method significantly reduces construction times, lowers costs for restoration to original conditions, and minimizes impacts on road traffic and the environment. Key advantages of guided pipe jacking procedures: - No intervention in above-ground infrastructure required, - Ability to perform works under obstacles (e.g. roads, sidewalks, lawns, property entrances, railway tracks), - Reduction of noise, vibration, and environmental pollution, - High accuracy of installation alignment, - Rapid mobilization of equipment and short completion times, - Lower risk of clashes with existing utilities, - No need for bentonite-based drilling fluids, - No excavation required during the jacking operation. Thanks to these features, guided pipe jacking is widely used for the construction of municipal networks, water and sewer connections, gas, fiber optic, and cable installations. Applications of guided pipe jacking Guided pipe jacking is suitable wherever installations are required without disturbance to the surroundings. Typical applications of jacking machines include: - Crossings beneath heavily used roads and transport routes, - Jacking under railway and tram lines, Cedpfx Afjxxhzwo Sjpw - Installations beneath watercourses and canals, - Installations under walkways, parking areas, courtyards, and industrial sites, - Property connections without excavating entire plots. With the ALUSTEER system, jacking is possible without drilling fluids (bentonite), which significantly reduces implementation costs and environmental impact. This technology can be used both in urban and non-urban areas—wherever precision, speed, and low impact are critical.
