对称同步转体工艺是采用扣索取代平衡重转体中的平衡墙的一种施工方法。它将全拱分为4个半跨拱箱,每半跨拱箱的拱脚置于相应的轻型转台上,分别根据两岸上、下游的实际地形,或搭简单支架,或浇土牛拱胎,在其上立模现浇或预制拼装拱箱,同时安装先预制好的拱箱间横向联系,然后用链条滑车(或千斤顶)收紧扣索,使拱箱脱模,应用简单的机械原理和借助铺有聚四氟乙烯的环形滑道,使每岸上、下游的半跨拱箱自行对称同步转体合龙。转体工艺如图
Symmetrical synchronous swivel process is a method of construction that replaces the balance wall in the balance weight swivel with a buckle. It divides the whole arch into 4 half-span arches, and each half span arch arch rests on the corresponding light turntable. According to the actual topography of the upper and lower reaches of the two sides of the strait, or by using simple brackets, In its pouring mold or prefabricated assembled arch box, while installing prefabricated arch between the horizontal link, and then use the chain block (or jack) to tighten the buckle, the arch box demolitions, the application of simple mechanical principles and Teflon-coated with a circular slide, so that each shore, the lower half of the cross-arch box synchronization of spontaneous synchrotron. Swivel process shown in Figure
