Banana bolts are also known as curved tunnel bolts. They are found both at the radial and circumferential joints of a tunnel. The diameters of these bolts range from M16 to M30. Curved tunnel bolts are available in different types of finishes and grades, such as Mild Steel and High-Tensile Steel. Their curved shape are designed to fit through the radial holes at the joints of the tunnel segments, which are then bolted together permanently.
We manufacture and supply many types of holding down bolts and accessories including tunnel bolts,fish bolts,anchor bolts,clip bolts,hook bolts,ect. We also offer washers and nuts of the required grade and dimensions to ensure a complete and secure connection.
Purpose and Function
Purpose and Function
Connecting segments: Banana bolts permanently connect the metal segments that form the tunnel's frame, allowing for the construction of undersea and underground tunnels.
Maintaining structural integrity: They are critical for keeping the tunnel stable by securely binding the segments, especially against external pressures like water and rockfalls.
Versatility: They are used in both radial and circumferential joints of the tunnel segments.
