Description

用于隧道宽幅防水板安装的充气式装备及施工和安装方法 技术领域
本发明涉及一种用于隧道宽幅防水板安装的充气式装备。本发明还涉及利用上述充气式装备用于隧道宽幅防水板安装的施工方法。
背景技术
目前隧道防水板一般采用1-1.5毫米厚聚乙烯防水板,该防水板幅宽3-7米,每平方米重量1.5公斤;3米幅宽的双线隧道,单幅重量达到150公斤;3米幅宽的单线隧道,单幅重量达到100公斤;7米幅宽的双线隧道,单幅重量达到330公斤;7米幅宽的单线隧道,单幅重量达到220公斤。
目前防水板的安装方式多是采用(简易台车)支架法配合人工安装方式,受托举重量限制只能采用3-4米幅宽的防水板,由于幅宽较窄,接缝较多,当搭接缝连接质量不到位时极易带来渗漏水的风险,焊接工作量较大,降低了安全保障系数,施工效率低下,安装质量得不到保证。而对于6-7米幅宽的防水板,由于单幅重量太重,原有安装工艺受到限制,无法使用。
为了解决防水板特别是宽幅防水板的安装问题,人们提出了多种安装防水板台车的设计思路,如CN20372800Y、CN102359385A、CN202090925U、CN202187780U、CN202300428U、CN201768021等专利公开的方案。但所有这些专利都只涉及到防水板的提升与在隧道中的牵引,未能解决防水板安装时的造型、尤其对隧道开挖轮廓不标准的情况下如何使防水板顶升到确切位置,以及为补偿灌注混凝土对防水板冲击所预留的下垂度的调整等安装中难以实现的技术难题。对于防水板顶升后的悬挂固定,现有技术也没有找到很好地解决办法。
目前在贵广客专已推广使用台车配合人工安装3.5米防水板的安装方式,取得了一定得进展,解决了安装3.5米幅宽的双线隧道可行性问题,但是,安装工效和安装质量问题人不令人满意。
发明内容

具体实施方式
下面结合附图和具体实施方式对本发明作进一步详细的说明。
一种用于隧道宽幅防水板安装的充气式装备,包括充气囊,如图1所示,充气囊由横向设置的拱形气囊1和多个直形气囊2,22,222构成,直形气囊2,22,222纵向设置,直形气囊2,22,222搭设在拱形气囊1上,拱形气囊1可以由多个气囊构成,各气囊之间通过连接件5组合,拱形气囊1两端部设置有安装基座4,安装基座4可调节位差,所述位差指的是高度,通过调节安装基座4的高度,可以抬升拱形气囊1。上述横向、纵向指的是隧道的横向、纵向。直形气囊2,22,222如采用圆柱形气囊。
所述充气式装备具有两个以上拱形气囊1,如图2所示,拱形气囊1之间纵向分布,多个直形气囊2,22,222搭设在拱形气囊上。如纵向分布两个拱形气囊1,拱形气囊1上搭设直形气囊2,22,222。直形气囊2,22,222的分布位置与防水板固定点位置相对应。
所述拱形气囊1与直形气囊2,22,222均设置有充气阀3,用于对拱形气囊1、直形气囊2,22,222进行充放气。
采用充气式装备,设备重量轻,非工作状态体积小,可移动性好,可以适应隧道轮廓超、欠挖的不规则轮廓,原理合理、科学,实现了一次安装幅宽7米的防水板的工艺和设备条件。
如图7所示,所述安装基座4固定在安装台车8上,采用充气式装备与安装台车8结合使用,共同构成防水板安装台车,解决了台车的定位、走行问题;土工布与防水板安装、固定、焊接的作业平台的有机结合,优化了防水板的顶升、定位、固定、焊接的各施工工艺环节;同时,施工人员移动方便、作业面开阔,拼装移动便捷,可大量节约高空作业的工作量,减轻了劳动强度,改善了作业条件,提高了防水板施工的质量和安装功效,提高的设备的标准化水平和设备重复使用能力,降低了防水板施工的设备摊销成本。
利用充气式装备在充放气条件下的体积变化,形成对防水板的托举、定位,将防水板托举到设计位置。利用在充放气条件下的体积变化,形成、调整防水板的垂度,进行准确定位,适应隧道断面开挖轮廓不标准的要求。此项技术原理的运用在国内、国际上没有使用先例,属于原始创新。
采用上述充气式装备用于隧道宽幅防水板安装的施工方法,包括以下步骤:
(1)防水板在充气式装备上展开与定位:将充气式装备在未充气状态下展开,按照安装垂度要求,将防水板展开固定在充气式装备的气囊上;
(2)防水板的抬升:将充气式装备放置在安装位置,将充气泵接口与充气阀3接口连接,对充气式装备进行充气,将防水板抬升至指定位置;
(3)防水板悬挂固定与幅间连接:将抬升的防水板连接在隧道轮廓面上,并对防水板之间进行连接。如在隧道轮廓面上先安装土工布,用射钉枪射钉将用于悬挂防水板的圆形塑料盘片与隧道轮廓中的预埋件固定,防水板抬升后,人工使用手持式超声波焊机将防水板焊接在隧道轮廓面上预埋件位置,然后配合超声波焊机,完成防水板交叉叠缝的焊接。将防水板连接在隧道轮廓面上的方法不限 于上述将防水板焊接在隧道轮廓面上预埋件位置,如采用吸盘连接固定防水板的方法。
(4)卸载:防水板安装完成后将充气式装备放气卸载,解除安装基座4与充气囊以及充气泵与充气囊的连接,开始下一循环防水板的安装。
上述方法是本发明充气式装备最简单的利用,在实施过程中,不利于防水板安装垂度的预留,预留的安装垂度也参差不齐,因此,本实施例还介绍另一种防水板安装方法,结合图1、3、4、5、6进行如下说明:该安装方法包括以下步骤:
(1)准备充气式装备,将充气式装备放置在防水板6安装位置;
(2)对充气式装备的拱形气囊1进行充气;
(3)将防水板卷7展开,使防水板6铺在充气式装备上,将防水板6展开的头端固定;沿防水板6展开的头端向防水板卷7方向,即图3、4、5、6中由右向左方向上,直形气囊依次称为第一直形气囊2、第二直形气囊22、第三直形气囊222、...、第n直形气囊,n为正整数;
(4)给第一直形气囊2充气,第一直形气囊2抬升防水板6高度,将防水板6沿图3中箭头方向拉动,从而将防水板6再次展开,使防水板6展开部分的长度增加;
由于防水板6展开的头端固定了,当第一直形气囊2充气时,防水板6的高度抬升,从而拉扯防水板卷7展开,使防水板6展开部分的长度增加。
(5)第一直形气囊2充气至极限或充气至预定高度后,将第一直形气囊2与其上的防水板6之间位置固定。如,可以采用夹子将防水板夹持在第一直形气囊2上,从而将其固定在第一直形气囊2上。
防水板6与第一直形气囊2的固定点为A,防水板6的头端(即展开的头端)固定点为B,当充气至极限或充气至预定高度后,AB点之间的距离变长,即AB点间防水板6的长度也变长,此步骤为形成垂度做好基础。
(6)将第一直形气囊2放气。第一直形气囊2放气后,AB点之间的距离变 短,由于防水板6固定在AB两点上,AB两点间防水板6的长度不会变化,从而形成安装要求的垂度。所述垂度如图4中AB两点间所示。
(7)按照步骤(4)~(6)的方式依次给第二直形气囊22、...、第n直形气囊进行充气、将直形气囊与其上的防水板6之间位置固定、给直形气囊放气;即:
如图5所示,给第二直形气囊22充气,第二直形气囊22抬升防水板6高度,从而将防水板6再次展开,使防水板6展开部分的长度增加;第二直形气囊22充气至极限或充气至预定高度后,将第二直形气囊22与其上的防水板6之间位置固定;将第二直形气囊22放气。如图6所示,形成CA两点间垂度。
给第三直形气囊222充气,第三直形气囊222抬升防水板6高度,从而将防水板6再次展开,使防水板6展开部分的长度增加;第三直形气囊222充气至极限或充气至预定高度后,将第三直形气囊222与其上的防水板6之间位置固定;将第三直形气囊222放气。
...
给第n直形气囊充气,第n直形气囊抬升防水板高度,从而将防水板再次展开,使防水板展开部分的长度增加;第n直形气囊充气至极限或充气至预定高度后,将第n直形气囊与其上的防水板之间位置固定;将第n直形气囊放气。
n大小根据防水板6长度和垂度大小实际来决定。
完成对所有直形气囊的操作,从而在铺设的防水板6上形成多道安装要求的垂度,形成的垂度质量高、形状统一;并可以根据实际情况,在产生垂度时进行大小调节。
(8)防水板6展开的头端解除固定,抬升安装基座4的高度,将防水板6抬升至安装位置,将防水板6连接在隧道轮廓面9(如图7所示)上。
在隧道开挖面上实现防水板垂度定位,提高了安装定位精度,减少了洞内登高作业,采用整体防水板抬升技术,优化了防水板1与开挖轮廓的固定工艺,消 除了焊接工艺容易造成焊穿破坏隐患,同时大大降低了劳动强度,提高了劳动效率。
本发明所称的垂度是指防水板6固定在隧道轮廓面9上时,相邻两个固定点之间防水板6的长度大于相邻两个固定点之间的距离,在重力的作用下,两固定点之间的防水板6下垂形成的弧面。垂度用于补偿灌注混凝土对防水板冲击。
上述两种方法中,所述充气式装备均可以通过安装基座安装在台车8上,如图7所示,施工人员移动方便、作业面开阔;拼装移动便捷的作业平台,可以大量节约高空作业的工作量,减轻了劳动强度,改善了作业条件,提高了防水板6施工的质量和安装功效,提高的设备的标准化水平和设备重复使用能力,降低了防水板6施工的设备摊销成本。
上述实施例不以任何方式限制本发明,凡是采用等同替换或等效变换的方式获得的技术方案均落在本发明的保护范围内。
