The welding seam welding seam: telescopic expansion, expansion joint fixation on the elevation and retest again, to determine any deformation, does not appear in the temporary fixed bias during the process, the anchor reinforcement and pre buried reinforced welded steel beam straight on both sides at the same time, any deviation, the deformation of anchor bars and pre specific steel beam buried reinforced welded on both sides at the same time, the best time to each. If there is difficulty, the first side of weld, to install a predetermined temperature, then the other side of all welding in the welding. If there is difficulty, the first side of weld, to install the preset temperature, then on the other side. At the same time all welded connection,M ruler, flatness detection of shaped steel beams. The feeler, then at the same time, using the 3 meter ruler at any time, flatness detection of shaped steel beams. The feeler gauge flatness control in 0 ~ 1mm, ~ to avoid jumping phenomenon. In order to avoid jumping phenomenon. 

pk10开奖结果The bridge expansion joint is to meet the requirement of bridge deformation, usually between two beam end hinged position between the girder and the abutment or bridge set expansion joints. The expansion joints in parallel, two direction perpendicular to the axis of the bridge, can free expansion, firm and reliable, the vehicle should be smooth running out no, jump and noise; to prevent rainwater and waste soil infiltration obstruction; installation, inspection, maintenance, remove the dirt will be simple and convenient. In the setting of expansion joints, rail and bridge deck pavement are disconnected.
