Method for quickly constructing fabricated viaduct
The invention provides an assembly type viaduct rapid construction method which comprises the following steps that S1, a bearing platform is installed on the ground surface, and a lower reserved steel bar is inserted into a lower guide hole; s2, the upper reserved steel bars are inserted into the upper guide holes, so that the lower prefabricated bent cap section is horizontally placed on the prefabricated column; s3, the grouting materials are conveyed into the grouting pipes of the branch pipes through the grouting header pipe; s4, grouting materials are injected into the upper guide holes through the grouting pipes; s5, a vertical pipe column and an inclined pipe column are placed on the two sides of the prefabricated column, and a cross beam is placed on the vertical pipe column and the inclined pipe column; and S6, the upper prefabricated cover beam section is hoisted to the designed position in place through a hoisting rope of the heavy crawler crane, the width and the length of the upper prefabricated cover beam section are smaller than those of the lower prefabricated cover beam section, and a padstone is arranged on the upper end face of the lower prefabricated cover beam section. The bar penetrating and pipe burying combined frames are arranged at the two ends of the prefabricated column, the rapidness and quality of on-site installation are guaranteed, and the prefabricated bent cap section is conveniently inserted into the reserved steel bars of the column during on-site hoisting.
本发明提供了一种装配式高架桥快速施工的方法，包括以下步骤：S1、在地表面上安装承台，将下预留钢筋插入下导孔内；S2、将上预留钢筋插入上导孔内，使下预制盖梁节水平放置在预制柱上；S3、通过压浆总管将灌浆料运送至各分管的压浆管内部；S4、通过注浆管向上导孔注入灌浆料；S5、在预制柱的两侧放置竖向管柱和斜向管柱，在竖向管柱和斜向管柱上放置横梁；S6、通过重型履带吊的吊绳将上预制盖梁节吊装至设计位置就位，上预制盖梁节的宽长度小于下预制盖梁节的宽度，下预制盖梁节的上端面设置有垫石上。通过预制柱两端采用穿筋埋管组合架，确保了现场安装的快速及质量，预制盖梁节现场吊装便于插进柱子预留钢筋内。
