Problems solved by technology

[0003] Traditional construction bridges often need to lay many steel pipe piles as the bridge support, and the height is fixed, the amount of work is large, the construction period is long, and ships of all sizes need to be stopped. Therefore, there is an urgent need to find a simple structure. Safe, reliable and non-stop shipping height-adjustable simple cable-stayed diversion ditch access bridge and construction method thereof

Abstract

The invention relates to a height-adjustable simple and simple cable-stayed diversion ditch convenience bridge and its construction method. The lattice columns are arranged in the ditch island of the diversion ditch, and first The pulley fixing plate and the second pulley fixing plate, and the lifting pulley block are set, and then the winch is set on the top of the lattice column, and the horizontal support bar of the column is arranged between the tops of the lattice column; the two ends of the I-beam upper flange plate are provided with lifting rings , and symmetrically pass through the belly of the lattice column. The two ends of the I-beam are placed in the anti-sway fixture and connected to the bridge deck lap plate. The I-beams are connected by horizontal welded pipes. Above all, it uses the setting of lattice columns, winches, steel strands and lifting and changing wheels to realize the adjustment of the upper and lower heights of the diversion ditch steel bridge, which can ensure the needs of river navigation and meet the needs of social and economic shipping.

Description

technical field [0001] The invention relates to a construction access bridge, in particular to a height-adjustable simple cable-stayed diversion ditch access bridge and a construction method thereof. Background technique [0002] When the full section of the river is closed, open channel diversion is usually required. In order to facilitate engineering construction and transportation needs, a temporary bridge will be built on the diversion ditch. This temporary bridge is called a construction bridge. There are many types of temporary bridges. According to its material and structural form, it can be mainly divided into circular tube type temporary bridge, cover plate type temporary bridge, stone arch type temporary bridge, log erected temporary bridge, steel type temporary bridge, Bailey sheet type temporary bridge, June 4th temporary bridge, floating type temporary bridge, cable Chain bridge, etc. [0003] Traditional construction bridges often need to lay many steel pipe p...
