10000 ton gravity canyon bridge anchorage

Описание: The construction site of the massive gravity anchor of the Huajiang Canyon Bridge features a huge concrete base embedded inside the mountain, with densely packed main cable steel wire bundles arranged in an orderly manner. Workers carry out construction operations among the intricate scaffolding, and many people marvel at the magnificent appearance of the bridge spanning a thousand kilometers across the canyon, but rarely pay attention to the most critical concealed project of this suspension bridge - the anchor. The Huajiang Canyon Bridge, as the world's largest high bridge, belongs to a super long span mountain suspension bridge. The load and bridge deck pressure of the entire bridge are transmitted to the anchorages on both sides through the main cable. The anchorages rely on their own weight of millions of tons of concrete to resist the huge tension of the main cable and prevent the bridge body from being pulled and displaced by the main cable. The geological conditions in the canyon area are complex, with numerous rock fissures on the mountain. The construction team needs to excavate a foundation pit deep into the mountain, reinforce it with multiple layers of rock mass, and then carry out large-scale concrete pouring. It is also necessary to strictly control the hydration heat to avoid the hidden danger of cracking in the giant foundation. Unlike cable-stayed bridges that rely on tower forces, the fate of suspension bridges is entirely determined by the anchorages on both sides. Without this giant concrete foundation buried deep in the mountains, a bridge with a span of one kilometer cannot stand stably over the canyon. The bridge is located in the deep karst mountains of Guizhou, with limited transportation conditions. The transportation of massive building materials and continuous pouring construction face numerous obstacles. The successful completion of the anchorage lays a solid foundation for the subsequent installation of the main cable and hoisting of the steel box girder.
