Abstract

The invention relates to a group anchor type tunnel anchor and a construction method, and relates to the technical field of bridge engineering. The anchor group type tunnel anchor comprises a front anchor chamber, a main cable and a plurality of small-size tunnel anchors, and the front anchor chamber is arranged at an opening of a mountain body; a main cable is arranged in the front anchor chamber, and the main cable is dispersed into a plurality of main cable steel strands through a cable dispersing saddle; the small-size tunnel anchor is connected with the main cable steel strand through a rigid anchoring conversion component. The anchor group type tunnel anchor has the beneficial effects that the main cable and the small-size tunnel anchors are connected through the anchoring conversioncomponents, it is guaranteed that the multiple small-size tunnel anchors can be stressed cooperatively, and therefore huge tension of the main cable can be evenly shared, the length of the anchor plug body does not need to be increased, the overall structure is stable, and the service life is long.

Description

technical field [0001] The application relates to the technical field of bridge engineering, in particular to a group-anchor tunnel anchor and a construction method. Background technique [0002] With the continuous development of my country's economy, science and technology, and the increasing demand for transportation, my country's bridge construction is entering a golden age. For areas that need to build extra-long-span bridges for traffic, you can choose to erect a suspension bridge. Suspension bridges, also known as suspension bridges, are a kind of cables that are suspended through cable towers and anchored to both banks (or both ends of the bridge) as the main load-bearing member of the upper structure. bridge. Suspension bridges are usually composed of main cables, stiffening beams, bridge towers, saddles, anchorages, suspension cables and other components. The main cable is the main load-bearing member of the suspension bridge. In addition to bearing its own dead...
