涵洞(dong)(dong)是(shi)指在(zai)公(gong)(gong)路(lu)(lu)工程建設(she)(she)中(zhong),為(wei)了使公(gong)(gong)路(lu)(lu)順利通(tong)(tong)過(guo)(guo)水(shui)(shui)渠不妨(fang)礙交(jiao)通(tong)(tong),設(she)(she)于路(lu)(lu)基(ji)下(xia)修筑于路(lu)(lu)面以(yi)下(xia)的(de)排水(shui)(shui)孔道(過(guo)(guo)水(shui)(shui)通(tong)(tong)道),通(tong)(tong)過(guo)(guo)這種結構可(ke)以(yi)讓水(shui)(shui)從公(gong)(gong)路(lu)(lu)的(de)下(xia)面流過(guo)(guo)。用(yong)于跨越天然溝谷洼地排泄洪水(shui)(shui),或橫跨大小道路(lu)(lu)作為(wei)人(ren)、畜和車輛的(de)立(li)交(jiao)通(tong)(tong)道,或農田灌(guan)溉(gai)作為(wei)水(shui)(shui)渠。涵洞(dong)(dong)主要由(you)洞(dong)(dong)身、基(ji)礎、端和翼墻等。涵洞(dong)(dong)是(shi)根(gen)據連通(tong)(tong)器的(de)原理(li),常用(yong)磚、石、混(hun)凝(ning)土和鋼筋混(hun)凝(ning)土等材料筑成。一般(ban)孔徑較小,形(xing)(xing)狀有管形(xing)(xing)、箱形(xing)(xing)及拱形(xing)(xing)等。
加工制作鋼波紋涵管后怎樣運送至現場?
針(zhen)對涵(han)(han)洞存在(zai)的(de)問題,推(tui)廣(guang)新型的(de)結構(gou)來改(gai)善傳(chuan)統涵(han)(han)洞的(de)不足,因此鋼波(bo)紋管管(guan)(guan)涵營(ying)運而生。施(shi)工簡略、周期短選用(yong)鋼(gang)(gang)(gang)波(bo)(bo)紋(wen)管(guan)(guan)施(shi)工工期短,土(tu)建(jian)與型材裝(zhuang)(zhuang)置可(ke)分隔實施(shi),然后(hou)進(jin)行整體組(zu)裝(zhuang)(zhuang)。鋼(gang)(gang)(gang)波(bo)(bo)紋(wen)管(guan)(guan)涵比較(jiao)鋼(gang)(gang)(gang)筋混凝(ning)土(tu)涵,可(ke)節(jie)約(yue)工期近(jin)1個多(duo)月,以長10m的構(gou)造(zao)物為例(li):束(shu)裝(zhuang)(zhuang)式波(bo)(bo)紋(wen)管(guan)(guan)現場(chang)裝(zhuang)(zhuang)置時(shi)(shi)刻約(yue)為0.5d,回(hui)填時(shi)(shi)刻約(yue)為1d;組(zu)裝(zhuang)(zhuang)式波(bo)(bo)紋(wen)管(guan)(guan)涵現場(chang)組(zu)裝(zhuang)(zhuang)時(shi)(shi)刻約(yue)為2d,回(hui)填時(shi)(shi)刻約(yue)為3d;
鐵路(lu)鋼波紋(wen)管
若選用(yong)圬工(gong)(gong)構造物(wu),修(xiu)建(jian)時刻(ke)通常為30d擺布,且施工(gong)(gong)工(gong)(gong)序繁瑣,消(xiao)耗(hao)很多的物(wu)力、人力,當(dang)涵洞處于(yu)重要(yao)路(lu)段時,其施工(gong)(gong)時刻(ke)長將直接(jie)影響(xiang)到(dao)該段路(lu)的施工(gong)(gong)疏(shu)通,而選用(yong)鋼波紋管能夠保證提早(zao)1個(ge)月(yue)的通車需求,所發生的經濟(ji)效益是無與倫比的,此(ci)外選用(yong)鋼波紋管現場裝置便利(li),通常選用(yong)螺栓銜接(jie),裝置只需簡略的裝置東西,能夠悉數選用(yong)人工(gong)(gong)安裝,不需運(yun)用(yong)大型設備。
耐(nai)久(jiu)性好鋼波紋管涵通常選用工廠加(jia)(jia)工制(zhi)作,出廠前涵管(guan)及配套附件均經過(guo)熱(re)浸鍍鋅(xin)處理,每一道制(zhi)造工序都有(you)嚴厲(li)的(de)質量檢測把(ba)關,運(yun)至施(shi)工現場后,在(zai)工地現場對其(qi)(qi)涂刷瀝青,進一步加(jia)(jia)強對其(qi)(qi)外觀的(de)維(wei)護防腐,以增(zeng)強其(qi)(qi)規劃運(yun)用年限,后期(qi)運(yun)營(ying)過(guo)程中(zhong)還可根據具體情況在(zai)管(guan)內(nei)壁(bi)增(zeng)涂瀝青涂層對其(qi)(qi)加(jia)(jia)強維(wei)護,比較傳(chuan)統(tong)圬工涵洞具有(you)耐久性(xing)好、維(wei)護費(fei)用低(di)、重建率低(di)一級優點。
公路鋼波(bo)紋管(guan)
鋼(gang)波(bo)紋涵管(guan)的發展在(zai)我們高(gao)速(su)公路建(jian)設過程中(zhong),涵洞(dong)是一種(zhong)(zhong)常見的結(jie)構(gou)也是一種(zhong)(zhong)十分重要的結(jie)構(gou),涵洞(dong)結(jie)構(gou)一直采用(yong)箱涵、蓋板涵、圓涵管(guan)、拱(gong)涵等(deng)幾種(zhong)(zhong)型(xing)式,涵洞(dong)在(zai)施工中(zhong)存在(zai)設計(ji)繁瑣(suo),施工時間周(zhou)期(qi)長,涵洞(dong)的孔徑(jing)周(zhou)期(qi)小容易出(chu)現沉降和跳車等(deng)問題。
鋼筋混凝土涵(han)洞在常年(nian)出現(xian)凍土、膨脹(zhang)土和(he)軟土燈(deng)不(bu)亮(liang)的(de)(de)(de)地質(zhi)條件地區和(he)高(gao)填方路(lu)段,地震多發地帶的(de)(de)(de)公路(lu)和(he)鐵(tie)路(lu)地帶的(de)(de)(de)運營中會出現(xian)不(bu)同(tong)程度(du)的(de)(de)(de)損害還會對涵(han)洞的(de)(de)(de)征途造成破壞,終會造成路(lu)面(mian)(mian)大面(mian)(mian)積的(de)(de)(de)塌陷給高(gao)速公路(lu)的(de)(de)(de)行車帶來很(hen)大的(de)(de)(de)不(bu)便還會給行車人帶來很(hen)大的(de)(de)(de)安全隱患。想(xiang)了解(jie)更多關于鋼波紋(wen)涵(han)管的(de)(de)(de)新聞動態請點擊:hanihanbj.com
