System of cable hoisting and swivel construction

Abstract

The invention belongs to the technical field of bridge engineering, and relates to a system of cable hoisting and swivel construction. The system of cable hoisting and the swivel construction comprises a first tower and a second tower which are symmetrically arranged on both banks of a river respectively, and further includes a load bearing subsystem, cable saddles for supporting a load bearing cable and a running trolley arranged on the load bearing cable, wherein the load bearing subsystem comprises the load bearing cable, and two ends of the load bearing cable are fixed on a first ground anchor and a second ground anchor which are oppositely arranged on the banks of the river respectively, and the cable saddles are internally provided with three layers of cable saddle pulleys, namely an upper layer cable saddle pulley, a middle layer cable saddle pulley and a lower layer cable saddle pulley; the cable saddles include a first cable saddle disposed at the top of the first tower and a second cable saddle disposed at the top of the second tower, and the system of cable hoisting and the swivel construction also includes a hoisting subsystem, a traction subsystem and a tower top cable saddle sidesway subsystem. According to the system of cable hoisting and the swivel construction, by means of the combination of cable hoisting and the swivel construction, the construction progress and the bridge construction quality of an arch bridge can be improved, and the construction cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to a cable hoisting and swivel construction system. Background technique [0002] Among the series of highway bridges in our country, the arch bridge, as an ancient bridge type, has the longest history of construction due to its unique technical advantages such as large spanning capacity, high bearing capacity, local materials, economical cost, low maintenance and repair costs, and beautiful appearance. , Strong competitiveness. The construction method of concrete-filled steel tube arch bridges is essentially a rigid frame method. Although the steel tube frame is much lighter than reinforced concrete, the erection of the steel tube frame itself is also very difficult after the span increases. For spans below 100m, the steel pipe skeleton is generally divided into three sections, and the hoisting mass is generally only tens of tons. According to the actual si...

Problems solved by technology

[0005] However, usually the construction of arch bridges uses the cable hoisting and swivel construction techniques separately. At present, there is no cable hoisting swivel system that combines the cable hoisting method and the swivel construction method to improve the construction progress and quality of the arch bridge and reduce the construction cost. cost
