Embodiment Construction
[0128] Such as figure 1 A construction process of segmentally assembled box girder is shown, the box girder to be constructed is a perforated beam, and each hole beam of the constructed box girder is composed of a plurality of box girder segments 1 assembled from back to front, and the box girder segment Section 1 is a reinforced concrete beam section;
[0129] When constructing the box girder to be constructed, the process is as follows:
[0130] Step 1. Box girder segment prefabrication: According to the conventional box girder prefabrication process, all box girder segments 1 used for assembling the constructed box girder are prefabricated in the prefabrication yard;
[0131] Step 2. Delivery of box girder segments: transport all box girder segments 1 in step 1 to the erection position of the box girder to be constructed by using a beam transport vehicle;
[0132] Step 3. Box girder erection: use the down-going bridge erecting machine to erect the constructed box girder, ...
