Luowen\Baimiaoe cap+ gravity U shaped abutment; Adopt 6*20m pre-stressed hollow slab beam for superstructure.
3、 主要工程量：Main construction Qty
白庙大桥全桥共有20米简支空心板梁30片，采用本方案架设25片，单跨5片；结构尺寸： ，。预制梁最大吊装重量(KN)边梁：295KN。
There are total 30 pieces of simple-erected hollow slab beam for whole Baimiao Bridge. 25 pieces of beam (5 beams per span) will be erected as per this M/S. Structural dimension: bottom width , height . Maximum lifting load (KN) of fabricated beam: 295KN, side beam.
4、 根据现场实际情况，拟架设白庙大桥1 — 5跨预制空心板梁采用GYJQ100t-30m型架 桥机，计划白庙大桥架桥机安装作业时间为：2011年10月下旬一2011年11月中旬(第六 跨不合格梁片采用双吊车组合吊装进行更换，更换时间为用架桥机把第五跨的空心板梁架 设完毕，过孔到第四跨时进行)。1 —5跨空心板梁架设作业时间为：2011年11月下旬一2012 年1月中旬；共计工期为60天。
According to actual situation on site, it is proposed that Model GYJQ100t-30m Beam Setter will be utilized to erect pre-fabricated hollow slab beams for s1to 5 th span of Baimiao Bridge. Planned installation period is:
From late Oct to middle Nov 2011 (Replacing and lifting of unqualified beam for 6th span shall be conducted by double mobile cranes. Such replacement work will be commenced when hollow slab beams for 5 span have been erected by beam setter and beam setter has passed to 4th span.)
Hollow slab beam erection for 1st to 5th span will be conducted from late Nov 2011 to middle Jan 2012, namely total construction will be about 60 days.
5、白庙大桥空心板梁架设施工：制作完成的空心板梁采用两台轮式吊车移出台座(存 梁区)至运梁车，由运梁车运至架桥机位进行安装。空心板梁吊装作业时间：压浆强度需 达到设计强度的80%，即40MPa。
Erection of hollow slab beam of Baimiao Bridge:
Fabricated hollow slab beam will be lifted and moved from pedestal (beam storage area) to trolley by two mobile cranes and then it will be transported to beam setter for erection by trolley.
Lifting time of hollow slab beam:
Grouting strength shall meet 80% of design strength, namely 40MPa.
6、对即将架梁的支承垫石的中线、标高、梁跨等进行复测，同时对砼梁进行测量，确 认无误后再进行移梁、运梁、架设等作业。
