摘要
结合节段梁短线法施工的特点与实践,针对因节段梁损毁造成成桥线形破坏出现“断链”的情况,介绍预留接缝、二次浇注的施工方法,该方法有效地解决了“断链”问题,恢复了成桥线形,满足了架设精度要求。
With reference to the construction features and practice of precast segmental girders by short line match method and in the light of the so-called ＂chain breaking＂ problem caused by damage to the geometric shape of the completed bridges due to the damage of the precast segmental girders, this paper presents a construction method of deck joint presetting and two-time concrete casting. The method mentioned herewith chain breaking＂, restore the geometric shape of the can effectively resolve the problem of the ＂ completed bridges and can also meet the precision requirements for erection of the segmental girders.
