Problems solved by technology
During the beam moving process of the bridge, the pier is independent and its size and space are very small. It is difficult to install the supporting seat required by the hydraulic jack, and there needs to be a space between the supporting seat and the box girder where the jack can be placed. The method is quite difficult in the process of lateral movement of the bridge box, and is limited by the stroke of the working parts of the jack, so it is not suitable for the situation where the distance to be moved is long, and the work efficiency of this method is low, which is not conducive to the construction of bridge erection. to promote

The invention discloses a cross sliding type erecting method for a separated box girder of a high speed railway, and aims to provide the cross sliding type erecting method for the separated box girder of the high speed railway with the advantages of time saving, labour saving, high working efficiency, stable work, convenient popularization and accurate and synchronous control. The method is realized by the following steps of: 1) laying an iron stool; 2) erecting a cross sliding type erecting device; 3) dropping the girder on a tow boat; 4) crossly sliding the box girder; 5) ejecting the girder and disassembling the cross sliding type erecting device; 6) dropping and positioning the girder; and 7) dropping the girder in position. The erecting method is suitable to be popularized and used in the cross sliding type erection of the separated box girder.
Description
technical field [0001] The invention relates to a method specially used for erecting or assembling bridges, in particular to a beam traverse erecting method for split boxes of high-speed railways. Background technique [0002] In recent years, in the bridge erection construction of my country's railway passenger dedicated lines, most bridge erecting machines do not have the function of traversing, and the bridge needs to be manually slid in place after it is placed. The bridge erecting machine with lateral movement function also adopts manual beam movement when erecting turnout girders and double-line girders at the same time. [0003] When the girder body of the bridge is relatively light, it is generally easier to erect the box girder directly by the bridge erecting machine, or to move the girder by sliding the girder or by manually moving the frame. However, when the bridge girder is relatively heavy, it is quite difficult to move the beam with a sliding plate and manual...
