cableway bridge abutment

Abstract

The invention relates to a cableway bridge abutment, and belongs to the field of bridge engineering. The cableway bridge abutment comprises an anchor plate and a foundation material, wherein the foundation material is arranged on the inner side of the anchor plate, a cable saddle used for laying a main cable is arranged at the top of the foundation material, and one end of the main cable winds across the cable saddle and then is provided with a connection adjuster; the end of the main cable is connected with anchor cables through the connection adjuster, the anchor cables are turned through the anchor plate, and simply supported plates are laid between the top of the anchor plate and the top of the cable saddle. The cableway bridge abutment is designed to be of a simply supported plate structure, so that excavation is reduced, and environment damage is relieved; stress on the anchor cables is more explicit, and conventional inspection and cable adjustment of the anchor cables are facilitated; and the span of the main cable can be reduced, materials are saved, and the construction difficulty is lowered.

Description

technical field [0001] The invention relates to an abutment of a cableway bridge, which belongs to the field of bridge engineering. Background technique [0002] Modern cableway bridge is a temporary bridge structure widely used in large-scale engineering construction. The vehicle load of the cableway bridge is transmitted to the load-bearing main cable through the bridge deck, and the main cable transmits the force to the anchorage anchored on both banks. The anchorage mainly bears pull. Commonly used anchorage forms are ridges, anchor piles, anchor rods and hybrid anchorages. An abutment (base material) is set between the anchorage and the main cable, and pulleys are set on the abutment to realize the steering of the main cable and bear the vertical force. [0003] The cableway bridge needs the abutment to realize the vertical support, the turning of the main cable and the connection between the bridge deck and the two banks. There should be enough space between the mai...

Problems solved by technology

[0004] The large amount of excavation in the existing technology will cause serious ecological damage; it is difficult to ensure the compactness of the backfill of the anchor pit, which will easily cause the subsidence of the subgrade above the anchor pit; the backfilled gravel soil will cause damage to the anchor cable; The frictional force is not easy to be quantified, so its influence on the sag of the main cable is not easy to predict; the vehicle load on the anchor cable in the anchor pit wrapped in gravel soil cannot be accurately considered; Routine inspection of anchor cables; at the same time, the span of the cableway bridge is large
