鋼波紋涵管作為一種新式技(ji)術(shu)(shu)(shu)在公路涵(han)洞(dong)工(gong)程施工(gong)中的具有很大的優(you)勢(shi)(shi),鋼(gang)波(bo)紋(wen)涵(han)管洞(dong)技(ji)術(shu)(shu)(shu)不只具有施工(gong)周期短、習慣才(cai)能強(qiang)、地基承載力要求(qiu)低的特(te)色,并且具有較強(qiang)的耐性,能夠大大削減施工(gong)的時刻,因此這種技(ji)術(shu)(shu)(shu)被運用(yong)。本文(wen)首(shou)要探討了鋼(gang)波(bo)紋(wen)涵(han)管洞(dong)的技(ji)術(shu)(shu)(shu)特(te)色以及優(you)勢(shi)(shi)。

鋼波紋涵管地基承載力較低的地區可以用嗎

鋼(gang)波紋(wen)涵管是(shi)一種柔性(xing)結構(gou),波紋(wen)管涵在結構(gou)上具(ju)有橫向(xiang)補償位移的(de)特(te)性(xing),能(neng)(neng)(neng)夠充分發(fa)揮鋼(gang)材抗拉(la)功能(neng)(neng)(neng)強(qiang)、抗變形才能(neng)(neng)(neng)優勝(sheng)的(de)特(te)色(se),具(ju)有較(jiao)大的(de)抗變形才能(neng)(neng)(neng)和(he)抗沉降才能(neng)(neng)(neng),特(te)別適合于軟土、膨脹(zhang)土、濕陷性(xing)黃土等地基承載力較(jiao)低的(de)區(qu)域和(he)地震(zhen)多發(fa)區(qu)域。

鋼波紋涵管的長處:

鋼波(bo)紋(wen)涵管從(cong)材料(liao)與(yu)結構(gou)和功能(neng)的實質(zhi)關(guan)系上(shang)剖析,選用柔性(xing)高強度(du)(du)的鋼波(bo)紋(wen)涵管洞因為軸向(xiang)(xiang)波(bo)紋(wen)的存在,使其具有(you)的受力(li)(li)特征,軸向(xiang)(xiang)和徑向(xiang)(xiang)一起(qi)散布因荷載(zai)引起(qi)的應力(li)(li)應變(bian),能(neng)夠更(geng)大程(cheng)度(du)(du)上(shang)渙散荷載(zai)的應力(li)(li)會集,更(geng)好(hao)地發揮鋼結構(gou)的優勢。鋼波(bo)紋(wen)涵管具有(you)施工(gong)(gong)工(gong)(gong)期短、重(zhong)量輕、安裝方便(bian)、耐久功能(neng)好(hao)、工(gong)(gong)程(cheng)造價低、抗變(bian)形才能(neng)強、削減(jian)養護費(fei)用本錢等長處。

鋼波紋涵管使用范圍:

1)鋼波紋涵(han)管是一種(zhong)柔性(xing)結構,波紋涵(han)管在結構上具有(you)橫向補償(chang)位移的特性(xing),能(neng)(neng)夠充分(fen)發(fa)揮鋼材抗(kang)拉功能(neng)(neng)強、抗(kang)變形(xing)才能(neng)(neng)優勝的特色(se),具有(you)較大的抗(kang)變形(xing)才能(neng)(neng)和抗(kang)沉降才能(neng)(neng),特別適合于軟(ruan)土(tu)(tu)、膨(peng)脹(zhang)土(tu)(tu)、濕陷性(xing)黃土(tu)(tu)等地(di)基承載(zai)力較低的區(qu)域(yu)和地(di)震(zhen)多發(fa)區(qu)域(yu)。

2)因為(wei)金屬鋼波紋涵(han)管施(shi)工(gong)簡單且施(shi)工(gong)工(gong)期短(duan)(一般一道涵(han)洞的施(shi)工(gong)時刻(ke)大約在10天-15天左右)縮(suo)短(duan)了多(duo)年凍(dong)土的裸露(lu)時刻(ke),凍(dong)融量小,故特別(bie)適用于多(duo)年凍(dong)土區域。

3)金屬鋼(gang)波紋涵管(guan)施工時(shi)對周圍(wei)環境的損壞小,適用于生(sheng)態環境脆弱(ruo)的區域(yu)。

4)該產品(pin)施工中只(zhi)需(xu)要對根底進行(xing)(xing)砂(sha)礫回填處理(li),對進出口(kou)進行(xing)(xing)混凝土或砌(qi)石(shi)施工處理(li),對砂(sha)、石(shi)材、鋼筋等用量(liang)小,非常(chang)實用于砂(sha)石(shi)缺乏的區域。

5)該產品選用標準化(hua)設計(ji)、工(gong)(gong)廠加工(gong)(gong)出(chu)(chu)產,出(chu)(chu)產不受(shou)環境影響,進行(xing)會集工(gong)(gong)廠化(hua)出(chu)(chu)產,出(chu)(chu)產周期短(duan),實(shi)用于質量(liang)要(yao)求(qiu)高,工(gong)(gong)期緊,根底差的工(gong)(gong)程項(xiang)目。

鋼波紋涵管施(shi)(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)藝流程較為特別(bie),在施(shi)(shi)工(gong)(gong)(gong)前(qian)要進(jin)行(xing)(xing)(xing)以(yi)下作(zuo)業(ye):施(shi)(shi)工(gong)(gong)(gong)前(qian)預備(bei)、施(shi)(shi)工(gong)(gong)(gong)放樣(yang)、設置(zhi)圍(wei)堰、排水(shui)清淤以(yi)及平(ping)整場所等。在施(shi)(shi)作(zuo)業(ye)業(ye)中要對其(qi)壓(ya)實度(du)(du)、含(han)(han)水(shui)量進(jin)行(xing)(xing)(xing)檢(jian)測(ce)(ce)(ce),接著對水(shui)準進(jin)行(xing)(xing)(xing)丈量,基(ji)于此,對施(shi)(shi)工(gong)(gong)(gong)根底進(jin)行(xing)(xing)(xing)分層回填(tian),檢(jian)測(ce)(ce)(ce)壓(ya)實度(du)(du)、含(han)(han)水(shui)量等,接著要組裝管節,對工(gong)(gong)(gong)程的密水(shui)情況(kuang)及管底縱坡進(jin)行(xing)(xing)(xing)檢(jian)測(ce)(ce)(ce),并對防(fang)腐(fu)涂層進(jin)行(xing)(xing)(xing)檢(jian)測(ce)(ce)(ce)與彌補。施(shi)(shi)工(gong)(gong)(gong)的關鍵的環(huan)節便是將涵(han)管進(jin)行(xing)(xing)(xing)就位,將涵(han)管兩側進(jin)行(xing)(xing)(xing)分層回填(tian),并要檢(jian)測(ce)(ce)(ce)壓(ya)實度(du)(du)、含(han)(han)水(shui)量等,終(zhong)進(jin)出口處(chu)理作(zuo)業(ye)。

由(you)此可見,鋼波紋(wen)涵管壓(ya)實度與含(han)水(shui)量的(de)(de)檢測作(zuo)業(ye)(ye)是鋼波紋(wen)管涵洞施工(gong)的(de)(de)一個必不可少的(de)(de)作(zuo)業(ye)(ye)。涵管組裝(zhuang)的(de)(de)工(gong)藝流程如下:首要對鋼波紋(wen)涵管管節進(jin)(jin)(jin)(jin)行(xing)檢查,接著(zhu)將(jiang)(jiang)涵管進(jin)(jin)(jin)(jin)行(xing)吊裝(zhuang),并(bing)將(jiang)(jiang)其運輸(shu)到施工(gong)場所(suo),施工(gong)材(cai)料到達(da)之后就要進(jin)(jin)(jin)(jin)行(xing)涵管進(jin)(jin)(jin)(jin)出口的(de)(de)校對作(zuo)業(ye)(ye),將(jiang)(jiang)法蘭盤及法蘭孔進(jin)(jin)(jin)(jin)行(xing)對齊,并(bing)上好(hao)螺栓(shuan)和螺母,將(jiang)(jiang)橡膠(jiao)或石棉(mian)密水(shui)墊(dian)填充(chong)進(jin)(jin)(jin)(jin)去(qu),終(zhong)擰緊螺栓(shuan),涵管內外的(de)(de)瀝青進(jin)(jin)(jin)(jin)行(xing)均勻側涂,涵管組裝(zhuang)作(zuo)業(ye)(ye)就完成了。

在進行鋼波紋管涵洞的施工時應注意以下要點:首要,應對施工的時節進行嚴格控制,盡量避免在冰凍時節進行施工,冰凍時節對工程施工質量有著嚴峻的影響,在冰冷冰凍氣候施工不只要嚴格要求根底填換材料,并且還要嚴格控制粉粘粒含量制,否則就會呈現涵管嚴峻損壞的情況。在對根底與涵管旁邊面、頂部的填料進行碾壓時應選用分層的形式,在進行壓實作業時應到達壓實度的要求,這樣才能有用避免涵管應力會集、涵管變形和涵管兩側的跳車。鋼波紋涵管為有用避免涵管在壓實后的地基外表滾動后構成凹形,應將涵管的位置安放好。//hanihanbj.com/
