鋼波紋涵管作為一種(zhong)新型技(ji)術在公路涵(han)洞工(gong)(gong)程施(shi)工(gong)(gong)中的(de)具有很大的(de)優勢,鋼波紋管(guan)涵(han)洞技(ji)術不僅具有施(shi)工(gong)(gong)周期短(duan)、適應能力強、地基承載力要求低的(de)特點,而且具有較強的(de)耐性,可以大大減少(shao)施(shi)工(gong)(gong)的(de)時間(jian),因(yin)而這種(zhong)技(ji)術被運用。
判(pan)斷鋼波紋涵管(guan)的質(zhi)量行不(bu)行,看這個細節很準
由于(yu)鋼(gang)波(bo)紋(wen)涵(han)管施(shi)工(gong)(gong)(gong)簡(jian)單且施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期短(一般一道涵(han)洞的施(shi)工(gong)(gong)(gong)時間(jian)大約(yue)在10天-15天左右)縮短了多(duo)年凍(dong)土的裸露時間(jian),凍(dong)融(rong)量小(xiao),故(gu)特別適用(yong)于(yu)多(duo)年凍(dong)土地區(qu)。鋼(gang)波(bo)紋(wen)涵(han)管采用(yong)標準(zhun)化設計、工(gong)(gong)(gong)廠(chang)加工(gong)(gong)(gong)生(sheng)(sheng)產(chan),生(sheng)(sheng)產(chan)不(bu)受(shou)環境影響,進行集中工(gong)(gong)(gong)廠(chang)化生(sheng)(sheng)產(chan),生(sheng)(sheng)產(chan)周期短,實(shi)用(yong)于(yu)質量要求高,工(gong)(gong)(gong)期緊(jin),基礎差的工(gong)(gong)(gong)程項目。
鋼波紋涵(han)(han)管(guan)使用范圍(wei):鋼波紋涵(han)(han)管(guan)施工時對周圍(wei)環境(jing)的(de)(de)破(po)壞小,適用于生(sheng)態環境(jing)脆弱的(de)(de)地(di)區。鋼波紋涵(han)(han)管(guan)在(zai)分片(pian)拼(pin)裝(zhuang)重(zhong)疊搭接后,每片(pian)上可在(zai)間隔位置收緊(jin)5-6處(chu)的(de)(de)螺(luo)母,為了方便(bian)后面角度的(de)(de)調整(zheng)。等涵(han)(han)洞通(tong)道(dao)拼(pin)接成功后,在(zai)均勻(yun)上緊(jin)所有地(di)方的(de)(de)螺(luo)母。
鋼波紋管(guan)(guan)涵具有施工(gong)(gong)(gong)工(gong)(gong)(gong)期短、重(zhong)量(liang)輕、安裝(zhuang)方便(bian)、耐久性能(neng)好(hao)、工(gong)(gong)(gong)程造(zao)價(jia)低、抗(kang)變形能(neng)力(li)強、減少(shao)養護費用成本(ben)等優點。現(xian)場(chang)指揮拼裝(zhuang)員(yuan)一名(ming)、安全(quan)員(yuan)一名(ming),指揮員(yuan)負責(ze)指揮起吊及施工(gong)(gong)(gong)人(ren)員(yuan)現(xian)場(chang)的(de)操作情況。安全(quan)員(yuan)負責(ze)施工(gong)(gong)(gong)現(xian)場(chang)的(de)安全(quan)管(guan)(guan)理(li)。
鋼波紋涵管(guan)是一種柔(rou)性(xing)結構,波紋管(guan)涵在結構上(shang)具(ju)有橫向(xiang)補償位移的(de)優良特(te)性(xing),可以充分發揮鋼材(cai)抗(kang)拉性(xing)能(neng)(neng)強、抗(kang)變形(xing)(xing)能(neng)(neng)力(li)優越的(de)特(te)點,具(ju)有較大的(de)抗(kang)變形(xing)(xing)能(neng)(neng)力(li)和(he)(he)抗(kang)沉降(jiang)能(neng)(neng)力(li),特(te)別(bie)適合于軟(ruan)土、膨脹土、濕陷性(xing)黃(huang)土等(deng)地(di)基承載力(li)較低的(de)地(di)區和(he)(he)地(di)震多(duo)發地(di)區。
鋼波紋(wen)涵(han)管的優點(dian):拼裝(zhuang)(zhuang)鋼波紋(wen)涵(han)管顧名思義就(jiu)(jiu)是需要(yao)在現場進(jin)行組裝(zhuang)(zhuang)的,所(suo)以(yi)在拼裝(zhuang)(zhuang)的時(shi)候(hou)就(jiu)(jiu)需要(yao)注(zhu)(zhu)意(yi)一(yi)些事項了!搭(da)(da)腳手架(jia)必須牢(lao)固,平穩,一(yi)定要(yao)注(zhu)(zhu)意(yi)安全。注(zhu)(zhu)意(yi)直徑(jing)兩端(duan)距離,以(yi)防安裝(zhuang)(zhuang)時(shi)通道變(bian)形。拼裝(zhuang)(zhuang)鋼波紋(wen)涵(han)管拼裝(zhuang)(zhuang)的時(shi)候(hou)相鄰地(di)方要(yao)搭(da)(da)建必須錯位布(bu)置,搭(da)(da)建處切(qie)記(ji)不能有4層(ceng)以(yi)上的重疊(die)。
鋼制波紋管涵
鋼波紋(wen)涵管(guan)施工(gong)(gong)中只需(xu)要對(dui)基(ji)礎(chu)進行砂(sha)礫回填處理(li)(li),對(dui)進出口進行混凝(ning)土或砌石(shi)施工(gong)(gong)處理(li)(li),對(dui)砂(sha)、石(shi)材、鋼筋等用(yong)量小(xiao),非常實用(yong)于砂(sha)石(shi)缺(que)乏的(de)地區(qu)。鋼波紋(wen)涵管(guan)從材料(liao)與(yu)結(jie)構(gou)和(he)功(gong)能的(de)本質關系上分析,采用(yong)柔性高強度的(de)鋼波紋(wen)管(guan)涵洞(dong)由于軸向(xiang)波紋(wen)的(de)存在,使(shi)其具有(you)優良的(de)受力特征,軸向(xiang)和(he)徑(jing)向(xiang)同時分布因荷載(zai)引起的(de)應(ying)力應(ying)變,可以更大程度上分散荷載(zai)的(de)應(ying)力集中,更好地發揮(hui)鋼結(jie)構(gou)的(de)優勢(shi)。(hanihanbj.com)
