涵洞(dong)是指在公路工程建設(she)(she)中，為了(le)使公路順(shun)利通(tong)(tong)過水渠不妨礙交(jiao)通(tong)(tong)，設(she)(she)于(yu)路基下(xia)(xia)修筑(zhu)于(yu)路面以下(xia)(xia)的排水孔(kong)道（過水通(tong)(tong)道），通(tong)(tong)過這(zhe)種結構(gou)可(ke)以讓水從(cong)公路的下(xia)(xia)面流過。用于(yu)跨越天然(ran)溝谷洼地排泄洪水，或(huo)(huo)橫跨大小道路作為人、畜和(he)(he)車輛(liang)的立(li)交(jiao)通(tong)(tong)道，或(huo)(huo)農田灌溉作為水渠。涵洞(dong)主要(yao)由洞(dong)身、基礎、端和(he)(he)翼墻(qiang)等。涵洞(dong)是根據連通(tong)(tong)器(qi)的原理，常用磚(zhuan)、石、混(hun)凝土和(he)(he)鋼筋混(hun)凝土等材料筑(zhu)成。一般(ban)孔(kong)徑較(jiao)小，形狀有管形、箱形及拱形等。

加工制(zhi)作鋼(gang)波紋涵(han)管后(hou)怎樣運送(song)至現場？

針對涵(han)(han)洞存(cun)在的問題(ti),推廣新(xin)型的結(jie)構來改善傳統涵(han)(han)洞的不(bu)足,因此鋼(gang)波紋管(guan)管(guan)涵(han)(han)(han)營運而生(sheng)。施(shi)工(gong)(gong)簡(jian)略、周期短(duan)選用鋼(gang)波(bo)紋管(guan)施(shi)工(gong)(gong)工(gong)(gong)期短(duan),土建與型(xing)材裝(zhuang)(zhuang)置可分(fen)隔(ge)實施(shi),然后(hou)進行整體組(zu)(zu)裝(zhuang)(zhuang)。鋼(gang)波(bo)紋管(guan)涵(han)(han)(han)比(bi)較鋼(gang)筋混凝土涵(han)(han)(han),可節約(yue)(yue)工(gong)(gong)期近1個多月,以(yi)長10m的構造物為(wei)例(li):束裝(zhuang)(zhuang)式波(bo)紋管(guan)現場裝(zhuang)(zhuang)置時(shi)刻約(yue)(yue)為(wei)0.5d,回填(tian)(tian)時(shi)刻約(yue)(yue)為(wei)1d;組(zu)(zu)裝(zhuang)(zhuang)式波(bo)紋管(guan)涵(han)(han)(han)現場組(zu)(zu)裝(zhuang)(zhuang)時(shi)刻約(yue)(yue)為(wei)2d,回填(tian)(tian)時(shi)刻約(yue)(yue)為(wei)3d;
