Bridge construction method and bridge dragging traction system

Abstract

The invention provides a bridge construction method and a bridge dragging traction system. The method comprises the steps that an ashore temporary support and a main pier are erected ashore, and a first sliding way part used for providing a sliding way is supported through the ashore temporary support and the main pier; a sliding supporting part is arranged on a sliding way of the first sliding way part in a sliding mode; the steel structure bridge is split into a first part which cannot be transported through a road and a second part which can be transported through the road, so that the first part is converted to a slide way of the first slide way part; then, an underwater temporary support, an anti-sliding pier and a main pier are erected in the water area, a second sliding way part used for providing a sliding way is supported through the underwater temporary support, the anti-sliding pier and the main pier in the water area, and a sliding way of the first sliding way part and a sliding way of the second sliding way part are in butt joint to form a dragging sliding way; and the traction sliding support part slides along the traction slide way. By means of the method, the difficulty of water transportation is lowered, and a dragging slide way and a traction system are convenient to build.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to a bridge construction method and a bridge drag system. Background technique [0002] At present, with the rapid development of bridge technology, long-span arch bridges are more and more used in large areas of water because of their curved shape and aesthetic feeling that other bridge types cannot match. Considering factors such as bridge structure and construction environment, steel structure arch bridges generally adopt dragging construction methods. However, there are still some problems in the towing construction technology of steel arch bridges in navigable waters. For example, the towing movement is slow and easy to deviate from the direction, and the towing weight is too large, which makes the construction dangerous. Contents of the invention [0003] In order to solve the defect that it is difficult to drag during the bridge construction process in the prior art, the ...
