Description

一种小间距多桥并行段箱梁同步运架施工方法 技术领域
本发明涉及多桥架设的施工方法，尤其是涉及一种小间距多桥并行段箱梁同步运架施工方法。
背景技术
目前铁路桥梁多桥梁共建、多桥并行线同步施工情况日益增多，桥梁与桥梁之间间距过于狭小，无法满足两台架桥机同步架梁的施工要求。同时，在架梁过程中还需穿越既有桥梁及其构筑物，对架梁过程中的运梁工作造成阻碍，影响架梁施工进度。
发明内容
本发明所要解决的技术问题是提供一种小间距多桥并行段箱梁同步运架施工方法，根据架梁顺序优化箱梁架设方案，交叉作业时设备调整操作简单，施工效率快安全性高。
本发明解决上述技术问题的技术方案如下：1.一种小间距多桥并行段箱梁同步运架施工方法，其特征在于，包括以下步骤：
1)架设第一双线桥；
2)所述第一双线桥架设完成后，架桥机右移架设第二双线桥，并通过所述第一双线桥运梁；
3)所述第二双线桥架设完成后，所述架桥机左移架设第二单线桥，并通过所述第一双线桥运梁；
4)所述第二单线桥架设完成后，所述架桥机右移架设所述第二双线桥延长出来的第三单线桥，并通过所述第一双线桥运梁；
5)所述第三单线桥架设完成后，所述架桥机右移架设所述第二双线桥延长出来的第四单线桥，并通过所述第一双线桥运梁；
6)所述第四单线桥架设完成后，所述架桥机左移架设第一单线桥，并通过所述第一双线桥运梁。
本发明的有益效果是：小间距多桥架设中，由于并行的桥梁与桥梁之间间距过小，不能同时容纳两台或多台架桥机，根据架桥顺序优化箱梁的架设方案，交叉作业，并利用已完成的线路桥进行运梁，同步架设施工，不但施工效率高，且安全性高。
在上述技术方案的基础上，本发明还可以做如下改进。
进一步，线桥两端分别设置有梁场和提梁机横移区，所述提梁机横移区安装有提梁机；
所述架桥机左移或右移时，返回所述梁场掉头或通过所述提梁机实现左移或右移。
采用上述进一步方案的有益效果是提梁机横移区位于并行段跨区域较小范围内，架桥机可根据实际情况在梁场或者提梁机横移区进行掉头后，进行下一次架桥操作，效率高，节约时间。
进一步，步骤1)至步骤6)中，架桥时先小里程方向架设，再大里程方向架设。
采用上述进一步方案的有益效果是架桥机需要返回梁场或者通过提梁机横移区进行掉头，运梁车在两个方向进行折返运输，从而利于架桥机进行左移或者右移。
当运梁车运梁过程中与架桥机相互干扰时，可通过旋转架桥机2#支腿缩短架桥机的宽度进行避让，从而保证运梁车和架桥机均能顺利通过，进而能够满足在桥梁紧密并行区多条线路同时进行架梁施工而互不影响。当架桥机需穿越即有既有门式墩时，可通过伸缩架桥机的各个支腿，整体调整架桥机 高度，实现架桥机穿越既有门式墩。
进一步，所述架桥机的主支腿伸出桥面的宽度小于2.4m。
采用上述进一步方案的有益效果是平行段的线桥间距过载，架桥机的主支腿伸出桥面过长，运梁车与架桥机会车时无法错开。
进一步，运梁车运梁时，所述运梁车为分离式运梁车。
采用上述进一步方案的有益效果是分离式运梁车行走较为灵活，适应小半径线路运梁，同时运梁车可协助架桥机在场地较小的空间完成场内掉头等。
进一步，所述梁场设置有提梁上桥区，且所述提梁上桥区包括至少一台横跨四桥六线的提梁机和至少一台单双共用的发运台座。
采用上述进一步方案的有益效果是提梁上桥去用于将箱梁从梁场移动至运梁车上，通过发送台座和运梁车运送至指定位置，简单快速。
进一步，所述提梁机横移区设置有至少一台横跨四桥六线的提梁机。
采用上述进一步方案的有益效果是提梁机用于提梁，同时也便于架桥机掉头。
进一步，步骤6)后还包括支座灌浆，待灌浆料的强度达到20Mpa后，拆除灌浆料模板。
采用上述进一步方案的有益效果是支座灌浆后将各线桥段连接稳固，便于后续进一步架设。

2)第一双线桥1架设完成后，架桥机可返回梁场掉头右移，架桥机右移架设第二双线桥2，并通过第一双线桥1运梁，架桥机的主支腿伸出桥面 的宽度小于2.4m，由于第一双线桥1的箱梁翼缘板相邻线桥上的运梁车或者架桥机发生干涉，因此，架桥机的主支撑腿伸出桥面的宽度不能过大。
3)第二双线桥2架设完成后，架桥机左移架设第二单线桥3，并通过第一双线桥1运梁，运梁车运梁时，运梁车为分离式运梁车。分离式运梁车行走较为灵活，适应小半径线路运梁，同时运梁车可协助架桥机在场地较小的空间完成场内掉头等。
4)第二单线桥3架设完成后，架桥机右移架设第二双线桥2延长出来的第三单线桥4，并通过第一双线桥1运梁。
当运梁车运梁过程中与架桥机相互干扰时，可通过旋转架桥机2#支腿缩短架桥机的宽度进行避让，从而保证运梁车和架桥机均能顺利通过，进而能够满足在桥梁紧密并行区多条线路同时进行架梁施工而互不影响。当架桥机需穿越即有既有门式墩时，可通过伸缩架桥机的各个支腿，整体调整架桥机高度，实现架桥机穿越既有门式墩。
5)第三单线桥4架设完成后，架桥机右移架设第二双线桥2延长出来的第四单线桥5，并通过第一双线桥1运梁。6)第四单线桥5架设完成后，架桥机左移架设第一单线桥6，并通过第一双线桥1运梁。步骤6)后还包括支座灌浆，待灌浆料的强度达到20Mpa后，拆除灌浆料模板。步骤1)至步骤6)中，架桥时均采用的是先小里程方向架设，再大里程方向架设，架桥机需要返回梁场或者通过提梁机横移区进行掉头，运梁车在两个方向进行折返运输，从而利于架桥机进行左移或者右移。
线桥两端分别设置有梁场7和提梁机横移区8，提梁机横移区8安装有提梁机。一具体实施例中，提梁机横移区8设置有至少一台横跨四桥六线的提梁机。
架桥机左移或右移时，返回梁场7掉头或通过提梁机实现左移或右移，梁场7还用于预制线梁。梁场7设置有提梁上桥区9，且提梁上桥区9包括 至少一台横跨四桥六线的提梁机和至少一台单双共用的发运台座。
实施例一
京雄城际铁路雄安车站汇集雄商、石雄城际、动车走行线等多条线的高架车站，雄安站南侧有新盖房南北堤分洪道(宽约1.4km)同时设有动车所。线路出雄安设有四桥六线，在新盖房南、北堤处分别采用最大跨80米的并行4联连续梁(两双两单)跨越泄洪大堤。过新盖房南堤后线路交错桥梁相互跨越由原四桥六线变为五桥六线。因工期要求需要各个线路桥梁同时进行施工，为满足预制梁施工及架设工期要求梁场选择在雄商双线桥与动车走行左线单线桥交错的位置设置梁场，满足单、双线预制梁同时进行桥上运梁架设施工的要求。因桥梁上下交错又相互并行，箱梁架设时架桥机需穿梭于门式墩施工、过连续梁时桥机支腿需躲避旁边一侧正在施工的连续梁等障碍，同时需解决平行桥梁线间距不满足并行双线桥一桥架梁另一桥运梁的施工要求。
并行线段(四桥六线长约1.4km)分别为石雄左线(单线)、动车左线(单线)、雄商线(双线)、动车右线&石雄右线(先双后单)，线间距分别为14m、5m、5m、5m，五桥六线段(长约1km)。桥群过新盖房南堤后石雄左单线桥标高逐步升高上跨雄商双线桥与动车走行左线单线桥两座桥梁，动车走行左线单线桥标高逐步下降下穿雄商双线桥，跨越的墩柱均采用门式墩其中门式墩最小净空8.4m。
并行段具体施工过程中，1)先架设雄商线，雄商线并行段架设完成后，2)架桥机右移架设动车右线&石雄右线的共线段，并通过雄商线运梁；3)动车右线&石雄右线的共线段架设完成后，架设动车左线，并通过雄商线运梁；4)动车左线架设完毕之后架设动车右线，架设动车右线时通过雄商线运梁；5)动车右线架设完毕后，架设石雄右线；6)石雄右线架设完毕后，最后架设石雄左线，同样通过雄商线运梁。
当雄商双线架设完毕，架桥机转移至石雄右线&动车右线上架设石雄右线&动车右线时，运梁车通过雄商线运梁。当运梁车与架桥机交汇时因梁翼缘板被架桥机2#支腿干扰，运梁车无法正常通过。此时，架桥机在非架梁的状态下可将2#支腿水平旋转至70°，使得2#支腿宽度由14.4m收窄至7.6m，缩短了架桥机的宽度，进而保证运梁车能够顺利通过。待运梁车通过2#支腿后，架桥机可以自行将2#支腿旋转至架梁状态，完成架桥机的过孔。
当架设线路线路上部遇门式墩时，架桥机会受到门式墩净空及净宽限制，正常架梁状态架桥机2#支腿高宽受限一般无法正常通过。现以最低净空高为例说明，架桥机过门式墩时，架桥机三个支腿可进行收缩，收缩后最高度由11.14m变为为7.6m，能够通过最小净空8.049m的门式墩，满足现场架梁施工。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
