鋼波紋涵管具有(you)耐腐(fu)蝕(shi)、分量輕、安裝簡(jian)略、運(yun)用壽命長的優點,其(qi)抗壓強(qiang)度(du)是普通(tong)塑(su)料管(guan)(guan)的2-3倍(bei)。中空(kong)結(jie)構內(nei)襯高強(qiang)度(du)鋼(gang)骨(gu)架,有(you)用減輕了管(guan)(guan)道本身的分量,大大進步了管(guan)(guan)環的剛度(du)。管(guan)(guan)道管(guan)(guan)壁上的外部壓力大部分由管(guan)(guan)壁內(nei)的鋼(gang)架承當,而沒(mei)有(you)鋼(gang)架的管(guan)(guan)壁上的壓力很(hen)小。

水危(wei)害的應用在一(yi)些區域,突(tu)發性暴雨較多,簡略對橋涵結(jie)構物形成危(wei)害。混凝土結(jie)構被(bei)破壞后(hou)不能(neng)再利用,有必要建筑(zhu)新的涵洞。施(shi)工時刻長,路面破損(sun)影響(xiang)人們(men)的出產日子(zi)。鋼波紋涵管被(bei)水破壞后(hou)可重復運用,施(shi)工處(chu)理簡略。
鋼(gang)波紋涵(han)管(guan)是由碳鋼(gang)板經冷(leng)成型加工而(er)成的(de)(de)管(guan)壁帶有(you)(you)波形截面的(de)(de)并且(qie)(qie)管(guan)體外表經耐腐(fu)蝕處理的(de)(de)金(jin)屬管(guan)道(dao)狀(zhuang)結構(gou)物,用(yong)(yong)來替代公路、鐵路工程中的(de)(de)砼涵(han)洞及小橋(qiao)等(deng)。具(ju)有(you)(you)必定(ding)柔性的(de)(de)高強度鋼(gang)波紋涵(han)管(guan)不(bu)僅進步了習慣地基和(he)地基變(bian)形的(de)(de)才能,并且(qie)(qie)有(you)(you)用(yong)(yong)地處理了地基不(bu)均(jun)勻沉(chen)降引起的(de)(de)涵(han)洞破壞問(wen)題。

鋼(gang)波(bo)紋(wen)涵管施工(gong)(gong)(gong)中(zhong)只需要對(dui)(dui)根底進(jin)行(xing)砂礫回(hui)填處(chu)理,對(dui)(dui)進(jin)出(chu)(chu)口進(jin)行(xing)混凝土或砌石(shi)(shi)施工(gong)(gong)(gong)處(chu)理,對(dui)(dui)砂、石(shi)(shi)材、鋼(gang)筋(jin)等用(yong)量(liang)小,非常(chang)實用(yong)于砂石(shi)(shi)缺少的區(qu)域(yu)。鋼(gang)波(bo)紋(wen)涵管選(xuan)用(yong)標準(zhun)化(hua)規(gui)劃、工(gong)(gong)(gong)廠(chang)加工(gong)(gong)(gong)出(chu)(chu)產,出(chu)(chu)產不受環(huan)境影響,進(jin)行(xing)集中(zhong)工(gong)(gong)(gong)廠(chang)化(hua)出(chu)(chu)產,出(chu)(chu)產周期(qi)(qi)短,實用(yong)于質(zhi)量(liang)要求高(gao),工(gong)(gong)(gong)期(qi)(qi)緊,根底差的工(gong)(gong)(gong)程項目。
在鋼(gang)波(bo)紋(wen)涵(han)管(guan)施(shi)(shi)工中要(yao)(yao)注(zhu)意(yi)的是:基(ji)坑開(kai)挖后,需(xu)要(yao)(yao)檢測地基(ji)的承載力;根底施(shi)(shi)工時,根底為(wei)砂礫層(ceng)的,需(xu)要(yao)(yao)做出預拱度;鋼(gang)波(bo)紋(wen)涵(han)管(guan)現場組裝(zhuang),要(yao)(yao)選用(yong)質量高的螺(luo)栓,中夾(jia)密封墊;配裝(zhuang)前內外要(yao)(yao)涂瀝青(qing);涵(han)管(guan)上方(fang)當回填土(tu)厚(hou)度超過30cm后,選用(yong)壓(ya)路(lu)機靜壓(ya),填土(tu)厚(hou)度超過60cm后,選用(yong)壓(ya)路(lu)機振壓(ya)。
基坑(keng)(keng)回填(tian)前,清(qing)理基坑(keng)(keng)底部原狀土,鏟除基坑(keng)(keng)內垃圾(ji),運(yun)(yun)用(yong)透水性資料進行(xing)基坑(keng)(keng)回填(tian)。分(fen)層填(tian)筑(zhu),填(tian)筑(zhu)厚度不(bu)大于15cm,選用(yong)沖(chong)擊夯(hang)夯(hang)實。某山區地帶高速路鋼波紋涵管導流(liu)洞運(yun)(yun)用(yong)工(gong)(gong)程(cheng)項(xiang)目(mu)事例有兩個u形(xing)管溝段(duan),本來的立交橋工(gong)(gong)程(cheng)施工(gong)(gong)規(gui)劃方案逾越,但由于征用(yong)土地和動遷,在(zai)執行(xing)環(huan)節(jie),導致了很多工(gong)(gong)程(cheng)進度落后。
為加快施工進度,將兩處高架橋改為填方路基,一起設置涵洞知足過人及過水的需求。由于涵頂填土較高,備選涵洞方案有拱涵及鋼波紋涵管2種,經由比較,選用在兩處填方路段均設置鋼波紋涵管的方案。//hanihanbj.com/
