Abstract

The invention relates to a composite tunnel anchor which comprises a first front anchor chamber, a first anchor plug body, a second front anchor chamber, a second anchor plug body and a cross beam, wherein the first front anchor chamber is arranged in a mountain body of an anchor site area; the first anchor plug body is located behind the first front anchor chamber, and the first anchor plug bodyis connected with one main cable of the suspension bridge through the first front anchor chamber; the second front anchor chamber is arranged in the mountain body of the anchor site area and is arranged in parallel with the first front anchor chamber at intervals; the second anchor plug body is located behind the second front anchor chamber, the second anchor plug body is connected with the othermain cable of the suspension bridge through the second front anchor chamber, and the second anchor plug body and the first anchor plug body are arranged in parallel at intervals; the cross beam is located between the first anchor plug body and the second anchor plug body, and the cross beam is integrally connected with the first anchor plug body and the second anchor plug body. According to the composite tunnel anchor, the scale and excavation difficulty of the tunnel anchor can be greatly reduced, and the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a composite tunnel anchor. Background technique [0002] With the vigorous development of the national economy and transportation, long-span bridges are widely constructed, and suspension bridges are the most important form of long-span bridges. Modern suspension bridges are composed of bridge towers, anchorages, main cables, suspension cables and other parts. Anchorage systems are generally divided into gravity anchorage, tunnel anchorage, soil anchorage and structural self-anchoring systems. [0003] In the related technology, the gravity anchor is formed by excavating the foundation pit and pouring large-volume concrete to form the anchor, relying on its own gravity to resist the pulling force of the main cable, so the volume is large and the cost is high, and the large-volume foundation pit greatly disturbs the surrounding environment; Tunnel-type anchorage is to...
