大跨径T梁预制及吊装技术研究
摘要
预应力钢筋混凝土梁桥在国内外桥梁建筑上占有重要的地位,具有强度高、自重小、节省钢材、耐久的特点,适用范围广,在我国已经普及,在各式装配式梁桥中以T形梁桥最为普遍,但在我国已拟定的标准跨径中只有10、13、16、20m四种公路梁桥标准设计,而随着桥梁施工工艺的发展和新型架桥机械的应用,T梁的跨径也在增长,50mT梁在桥梁工程中已经很普遍,并呈现大幅增长的势头,但对于50mT梁预制及吊装技术研究的文献资料却很少,成为制约T梁发展的瓶颈。因此,本课题所研究的50mT梁预制及吊装技术对施工具有巨大的指导意义。本课题在研究过程中进行了大量调研工作,结合在建中的肃临线衡水市区段一级公路石德、京九铁路跨线桥工程,在参考有关文献的基础上深入50mT梁预制、吊装工程一线,使理论紧密联系实际,具有很强的说服力,在调研中采集了部分预制、吊装图片,使课题更具形象化。在研究中主要从以下四方面进行了研究:①工程概况;②50m预应力T梁的预制、张拉及压浆工艺;③50mT梁桥上运输;④架桥机跨铁路架梁。
在介绍T梁预制及张拉工艺的同时,进行了台座预拱度、掺外加剂混凝土配合比的确定、伸长量等理论的计算,为了保证架桥机架梁的安全性及合理性,对跨桥运输T梁进行了计算检验。在整个计算过程中,笔者采集了大量的现场数据进行分析,并将理论计算公式算得的结果与桥梁建设专家的意见进行了对比分析,运用到工程建设实际中,验证了本文理论公式的合理性,并对其他相似地区50mT梁预制与架设施工提供了宝贵的经验。
Prepare in response to the dint reinforced concrete beam bridge a building at the domestic and international bridge up occupy an important position, have strength high , self-respect small, economical steel materia , enduring of characteristics, apply scope wide, have already make widely available in the our country, the T form beam bridge is the most widespread in the every kind of assemble type beam bridge, but only 10、13、16 and 20 m four kinds of highway beam bridge standardses design in our country have already dreamed the standard across the path,but along with the development of bridge construction craft and new bridging machine apply, the T beam acrosses path also growing,the 50m T beam is already very widespread in the bridge engineering,also present the situation of significant growth, but prepare to make and mourn cultural heritage data of pack the technique research to the 50 mT beam few,become the check and supervision T beam the bottleneck of the development.Therefore, the 50m T beam that this topic study prepares to make and mourns to pack a technique have huge instruction meaning to the construction. This topic is in the process of study in carried on a great deal of investigation work, Combine just in the construction engineering of Shide、Jingjiu railroad acrosses line bridge engineering of Hengshui downtown segment one class highway, in making reference to the foundation concerning cultural heritage go deep into the spot of 50m T beam to prepare to make、mourn to pack engineering, make theories close the contact be actual, have very strong conviction, collected part picture of prepare to make, mourn to pack in the process of investigating research, make the topic more image to comprehend. Main from the following everywhere the noodles carried on a research in the process of study:①Engineering general situation;②Prepare to make、Pull to stretch and press syrup craft of the 50m prepares in response to the dint T beam;③Transport on the 50m T beam bridge;④The bridging machine acrosses railroad beam.
At introduce T beam to prepare to make and Pull to stretch 's craft of in the meantime,carried on a set to prepare an arch degree、join addition's concrete match to compare really settle、elongation quantity etc. theories calculation, for promising the safety and rationality of the bridging machine install beam, carry on calculation examination to acrossed the bridge conveyance T beam, in wholely the calculation process, the writer collected a great deal of spot data to carry on analysis, also compute theories formula to calculate of result and bridge constucted the expert's opinion to carry on contrast analysis, make use of engineering construction physically medium, verified the rationality of this literary style ory formula, and for Other alike regions 50m T beam prepares to make with installed construction provide precious experience of 50m T beam.
