A continuous beam bridge for the 40 +80 +80 +40 hole arrangement, the main beam of concrete strength C50, the use of hanging basket cantilever construction process, the basket structure for the triangular cable-stayed, the length of the closure section of 2m, close Seal of the skeleton made of steel. Question: (1) What are the casting processes? Should be divided into several T structure for construction? (2) the bridge with the first side of the cross-cross after the closure of the construction measures, please meet the closure of the construction should meet the requirements? (3) how to complete the system conversion?
In the lower structure after the completion of the structure, the platform can be erected on the platform bracket can be erected if the high pier can be erected legs, but must be pre-pressure to eliminate plastic deformation to be elastic deformation to throw high but also to calculate the construction of pre-camber and zero Block the axis to meet the design requirements, in the upper part of the pouring of the block Note that the layout of the prestressed pipe to meet the design requirements but also embedded in the finishing thread used to fix the hanging blue in the pouring of the zero section to do temporary consolidation,
Chisel addition to the temporary consolidation system is converted from T-structure to continuous beam in the form of the maximum negative moment
He is carrying the blue construction of the unbalanced bending moment after the completion of the block on the zero block after the assembly of hanging blue hanging blue assembly after the completion of the pre-pressure to remove the plastic deformation of the elastic deformation value in the future construction and construction of each stage Pre-camber length together in the construction to ensure that the axis does not bias in each section of the blue line before walking to carry out the elevation measurement to ensure that the closure of Longkou's height difference within the scope of the specification or the scope of the owners to take the minimum
