Transformation method for orthotropic steel bridge deck

Abstract

The invention relates to a transformation method for an orthotropic steel bridge deck. According to the technical scheme, the transformation method for the orthotropic steel bridge deck includes the following steps that a measuring scheme of a main control point of a whole bridge of an old bridge structure is formulated, and therefore the whole line form of the old bridge structure is obtained; secondly, a measuring scheme of control points of all segments of the old bridge structure is formulated, and main control sizes of all the segments of the old bridge structure are obtained; thirdly, a position scheme of existing holes, existing splice plates and existing support plates is formulated according to the types and sizes of existing holes, newly-formed holes and / or construction site assembled and drilled holes which need to be used in matching and connecting a novel structure and the old structure; fourthly, the precast orthotropic steel bridge deck is connected with the old bridge structure through angle steel bolts. According to the transformation method for the orthotropic steel bridge deck, a measuring control method of a system is used for effectively obtaining the deformation characteristics of the old bridge structure, the practical line form of the oil bridge structure is simulated, so that a manufacture line form of the newly-manufactured structure is determined, matching and installing of the new structure and the old structure are achieved, the difficulty in installing and erecting on a construction site is lowered, and installation efficiency is improved.

Description

technical field [0001] The invention relates to a method for transforming orthotropic steel bridge decks, and belongs to the technical field of railway bridge design and construction. Background technique [0002] At present, many existing bridges in our country have various damages and defects to varying degrees. How to strengthen and transform these bridges is already a very large and important project. At present, the reconstruction and reinforcement technology of old bridges in our country is more focused on the research on reconstruction and reinforcement methods, bridge bearing design, calculation, etc., but less research on the measurement and control of the deformation of old bridges, which will affect the new and old structures. Matching connections bring difficulties and increase the difficulty and workload of site installation and erection. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a reconstruct...
