Audited Supplier Our Seamless Pipe for Tunnel Portal Underpinning is a reliable and efficient solution for reinforcing foundations and stabilizing slopes in tunneling projects. With a diameter range of 50 to 300 mm and a length of up to 12 meters, these micropiles are designed to meet various project requirements.
The installation process is simple and fast, utilizing mechanical equipment such as rotary drilling rigs, electric drilling rigs, and extrusion drilling rigs. Cement and rebar are injected simultaneously during the drilling process to enhance the adhesion between the soil and the pile. Once the hole is drilled to the desired depth, the steel bar is inserted and the bottom of the hole is filled with concrete, which is then compacted using equipment like a vibrator.
Our micropiles offer numerous advantages. Their smaller diameter allows for installation in smaller sites and through lower water tables. They can be used in various geological and soil conditions, including soft soils, viscous clays, wetlands, and rocks. The design and construction of the micropiles can be customized to meet specific load and stress requirements.
These micropiles have been widely used in engineering projects, including the reinforcement of large buildings, support for bridges, bunkers, and underground structures, and as part of seismic support systems to improve the stability and stiffness of buildings.
Choose our Seamless Pipe for Tunnel Portal Underpinning for a flexible and efficient foundation support solution that excels in a variety of geological and soil conditions. Its quick installation and excellent load-bearing capacity make it an essential component in construction and civil engineering.
