摘要

宿淮高速淮安西互通连接线盐河大桥总长577.04m。桥梁跨越淮阴区境内的盐河。跨盐河大桥主桥采用80+140+80m三跨变截面预应力混凝土连续箱梁。引桥全部采用30m等截面部分预应力混凝土组合箱梁,桥孔布置按照桥头填土高度H=6.0m左右进行控制。其中往宿淮高速淮安西互通方向引桥桥跨布置为6×30m,六孔一联,先简支后连续;往淮安市区方向引桥为三孔一联先简支后连续部分预应力混凝土组合箱梁,桥跨布置为3×30m。上场伊始,他们提出了“以一流的管理,建一流的工程,展铁军风采”的口号,建立健全了严格的规章制度,制订了确保部优,力争国优的质量目标。他们把整个工程划分成施工前期准备工作、钻孔桩软基处理、路基桥涵施工三个阶段,对每个阶段的任务进行细化,项目领导分工负责,现场指挥,项目部各科室承包施工作业队,工资收入与施工队完成任务、安全、质量挂钩,责任到人。仅用了15天时间,建成了全线标准最高,设备精良的试验室,并首家通过建设单位的验收。20天完成了项目部的临设任务,一个月建成了11公里便道和4座便桥的施工任务,率先在全线拉开了钻孔桩和路基施工的序幕,在建设单位组织的施工前期准备工作检查中获得第一名,宿淮高速公路指挥部在该标段召开了现场会,要求全线施工单位要向他们学习。

Sleeps west Huai high speed Huai An to exchange ties salt river bridge total length 577.04m. The bridge surmounts the Huaiyin area domestic salt river. The cross salty river bridge main span uses 80+140+80m three cross variable cross-section prestressed concrete continual box Liang. The approach span uses 30m completely constant section partial prestressed concrete combination box Liang, the bridge opening arrangement carries on the control according to bridge head depth of fill H=6.0m about. And toward sleeps west Huai high speed Huai An to exchange the direction approach span bridge span arrangement for 6×30m, a six association, after first simple support, continuously; After the Huai An urban district direction approach span is as soon as three unite the first simple support continuously partial prestressed concrete combination box Liang, the bridge span arrangement for 3×30m. Goes on stage the beginning, they proposed “by the first-class management, constructs th
