進(jin)出(chu)口可采(cai)用(yong)由(you)制造的金(jin)屬波紋(wen)管(guan)節,有直管(guan)和與路基(ji)邊坡司坡率的斜上啟(qi)齒兩種方式(shi);也(ye)可依據所在地(di)域的細致狀況采(cai)用(yong)漿(jiang)砌(qi)(qi)(qi)片(pian)(pian)石或(huo)十砌(qi)(qi)(qi)片(pian)(pian)石砌(qi)(qi)(qi)筑。普通在冰冷地(di)域,采(cai)用(yong)金(jin)屬波紋(wen)管(guan)節或(huo)干砌(qi)(qi)(qi)片(pian)(pian)石。在其與河床接頭處進(jin)出(chu)U空中及(ji)邊坡一(yi)定范圍內應設置雙(shuang)層漿(jiang)砌(qi)(qi)(qi)片(pian)(pian)石或(huo)千(qian)砌(qi)(qi)(qi)片(pian)(pian)石鋪砌(qi)(qi)(qi),以避(bi)免(mian)沖刷。
并作必要(yao)的防滲處置;為避免路基土梗塞涵(han)洞洞口,在(zai)洞口與路堤交匯處做(zuo)一定高度和厚(hou)度的漿砌片石或干砌片石墻(也(ye)可采用(yong)(yong)(yong)鉛絲籠)防護。關于大(da)口徑(jing)鋼波(bo)紋管洞應采用(yong)(yong)(yong)拼裝(zhuang)式涵(han)管施(shi)工技術(shu),管徑(jing)2.0~2.5m構造(zao)宜采用(yong)(yong)(yong)管節(jie)對接(jie),管徑(jing)大(da)于等于3.0m構造(zao)宜采用(yong)(yong)(yong)片狀弧形波(bo)紋板螺(luo)絲銜接(jie)拼裝(zhuang)。

施(shi)工(gong)(gong)(gong)放樣依據設計(ji)提供的導(dao)線點、直線曲線轉角表及涵洞設計(ji)圖(tu)紙(zhi),推算出鋼波(bo)紋管縱橫軸線坐標運(yun)用全站儀中止總體定(ding)位及細部(bu)放樣。伴隨著施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝(yi)展開(kai)趨(qu)向與展開(kai),公路樹立工(gong)(gong)(gong)程總數(shu)持續增(zeng)(zeng)加,難度系數(shu)也在增(zeng)(zeng)加。為保證構造堅(jian)固靠譜,思索工(gong)(gong)(gong)程施(shi)工(gong)(gong)(gong)基(ji)本樹立,提升(sheng)質量管理是十分必要的。
鋼(gang)波紋管(guan)是普(pu)遍的技術措(cuo)施(shi),在(zai)樹立工(gong)程中獲得合理(li)運(yun)用。為(wei)確保施(shi)工(gong)質(zhi)量,不但要嚴苛(ke)遵照消費流程,貫徹落實施(shi)工(gong)工(gong)藝對策,也要提(ti)升(sheng)質(zhi)量控(kong)制,創建健(jian)全的質(zhi)量管(guan)理(li)方(fang)案(an)。對公路涵洞來說,涵洞的不平(ping)均沉降(jiang)是其(qi)毀(hui)壞的主要方(fang)式(shi)。
從資料與構造和功用的實質關系上剖析,采用柔性、高強度的鋼波紋管洞,不只具有順應地基與根底變形的才干,能夠處置斟地基根底不平均沉降招致的涵洞毀壞問題,而且鋼波紋管洞由于軸向波紋的存在使其具有的受力特征。//hanihanbj.com/
