涵(han)洞是指在公(gong)(gong)路工程(cheng)建設中(zhong)，為(wei)(wei)了使(shi)公(gong)(gong)路順利通(tong)過(guo)水(shui)渠不妨(fang)礙交(jiao)通(tong)，設于(yu)路基下(xia)修(xiu)筑于(yu)路面以下(xia)的(de)排(pai)水(shui)孔道(dao)(dao)（過(guo)水(shui)通(tong)道(dao)(dao)），通(tong)過(guo)這種(zhong)結(jie)構可以讓水(shui)從公(gong)(gong)路的(de)下(xia)面流過(guo)。用于(yu)跨越天然溝谷(gu)洼地排(pai)泄洪(hong)水(shui)，或橫跨大小道(dao)(dao)路作為(wei)(wei)人、畜和車輛(liang)的(de)立交(jiao)通(tong)道(dao)(dao)，或農(nong)田灌溉作為(wei)(wei)水(shui)渠。涵(han)洞主要由洞身、基礎、端和翼墻等。涵(han)洞是根(gen)據連通(tong)器的(de)原(yuan)理，常用磚、石、混凝(ning)土和鋼(gang)筋(jin)混凝(ning)土等材料筑成。一般孔徑(jing)較小，形(xing)狀有管形(xing)、箱形(xing)及(ji)拱形(xing)等。

加工制(zhi)作鋼波紋(wen)涵管后怎樣運送(song)至現場？

針對涵洞存在的(de)(de)問題,推(tui)廣新(xin)型的(de)(de)結構來(lai)改善(shan)傳(chuan)統涵洞的(de)(de)不足,因此(ci)鋼(gang)波(bo)紋(wen)管管(guan)(guan)(guan)涵營(ying)運(yun)而生(sheng)。施(shi)工簡略、周期短(duan)選用鋼波(bo)(bo)紋(wen)管(guan)(guan)(guan)施(shi)工工期短(duan),土建與(yu)型材裝置(zhi)(zhi)可分隔實施(shi),然后進行(xing)整體組(zu)(zu)裝。鋼波(bo)(bo)紋(wen)管(guan)(guan)(guan)涵比較鋼筋混凝(ning)土涵,可節約(yue)工期近1個多月,以(yi)長(chang)10m的構(gou)造物為例:束裝式波(bo)(bo)紋(wen)管(guan)(guan)(guan)現場裝置(zhi)(zhi)時(shi)刻(ke)(ke)約(yue)為0.5d,回(hui)填時(shi)刻(ke)(ke)約(yue)為1d;組(zu)(zu)裝式波(bo)(bo)紋(wen)管(guan)(guan)(guan)涵現場組(zu)(zu)裝時(shi)刻(ke)(ke)約(yue)為2d,回(hui)填時(shi)刻(ke)(ke)約(yue)為3d;

若選用(yong)圬工(gong)(gong)構(gou)造(zao)物,修建(jian)時(shi)刻通常(chang)為30d擺布,且施(shi)工(gong)(gong)工(gong)(gong)序繁瑣(suo),消耗很多的(de)(de)物力、人(ren)力,當涵洞(dong)處于重要路段時(shi),其(qi)施(shi)工(gong)(gong)時(shi)刻長將直接(jie)影響到(dao)該(gai)段路的(de)(de)施(shi)工(gong)(gong)疏通,而選用(yong)鋼(gang)波紋(wen)管能夠保證提(ti)早1個(ge)月(yue)的(de)(de)通車需(xu)求,所發生的(de)(de)經濟(ji)效(xiao)益是無與倫比的(de)(de),此(ci)外選用(yong)鋼(gang)波紋(wen)管現場裝(zhuang)(zhuang)置(zhi)便利,通常(chang)選用(yong)螺栓銜接(jie),裝(zhuang)(zhuang)置(zhi)只需(xu)簡略的(de)(de)裝(zhuang)(zhuang)置(zhi)東(dong)西,能夠悉數選用(yong)人(ren)工(gong)(gong)安(an)裝(zhuang)(zhuang),不需(xu)運(yun)用(yong)大型設(she)備。

耐久性好(hao)鋼波紋(wen)管涵通常選用(yong)工(gong)(gong)廠加工(gong)(gong)制作,出廠前(qian)涵(han)管及配(pei)套(tao)附件均(jun)經過熱浸鍍(du)鋅處理(li),每一道制造工(gong)(gong)序都有嚴厲的質量檢測把關,運(yun)至施工(gong)(gong)現(xian)場(chang)后,在(zai)工(gong)(gong)地現(xian)場(chang)對(dui)其(qi)(qi)涂刷(shua)瀝青,進一步加強(qiang)(qiang)對(dui)其(qi)(qi)外觀的維護防腐,以增強(qiang)(qiang)其(qi)(qi)規劃運(yun)用(yong)年限,后期運(yun)營(ying)過程中還可根據(ju)具體情(qing)況在(zai)管內壁(bi)增涂瀝青涂層對(dui)其(qi)(qi)加強(qiang)(qiang)維護,比(bi)較傳統圬工(gong)(gong)涵(han)洞(dong)具有耐久性好、維護費用(yong)低、重建率低一級優(you)點。

公路(lu)鋼波紋管

鋼波紋涵(han)管(guan)的發展在我們高速公(gong)路(lu)建設過程中,涵(han)洞是一種常(chang)見的結構也是一種十(shi)分重要的結構,涵(han)洞結構一直采用箱涵(han)、蓋板(ban)涵(han)、圓涵(han)管(guan)、拱涵(han)等幾種型式,涵(han)洞在施工中存在設計繁瑣,施工時(shi)間周(zhou)期(qi)長,涵(han)洞的孔徑周(zhou)期(qi)小容(rong)易出(chu)現沉降和跳(tiao)車(che)等問(wen)題。
