Abstract

The invention discloses a construction method for a steel box girder, comprising the following steps: step 1, manufacturing and assembling of steel box girder segments; step 2, arranging a jacking pier, using static penetration to measure the bearing capacity of the foundation, and confirming that it satisfies Construction can be carried out only when the bearing capacity of the foundation meets the requirements; the jacking piers are erected on the steel pipe piles; the third step is to set up the walking jacking equipment; Beam segment, to close the steel box girder segment. It can be widely used in the technical field of steel box girder construction.

Description

technical field [0001] The invention relates to the field of steel box girder construction. More specifically, the present invention relates to a construction method of a steel box girder. Background technique [0002] Steel box girder, also known as steel plate box girder, is a common structural form of long-span bridges. Generally used on bridges with large spans, it is called steel box girder because it looks like a box. [0003] The steel box girder construction is one of the essential steps in the bridge construction process, but the current steel box girder construction generally has the problems of complicated procedures and low work efficiency. SUMMARY OF THE INVENTION [0004] In order to achieve these objects and other advantages according to the present invention, a method of construction of a steel box girder is provided, comprising the following steps: [0005] Step 1. Fabrication and assembly of steel box girder segments [0006] Determine the required nu...
