鋼(gang)波紋管在填(tian)土之前，在鋼(gang)波紋管的旁邊面每20-30cm高(gao)度作出(chu)填(tian)高(gao)標(biao)明，以便確定每層的壓實程度及狀態。鋼(gang)波紋管兩(liang)邊回填(tian)應一起進(jin)行，壓實落差應小于(yu)(yu)30cm，關于(yu)(yu)有(you)端部擋(dang)墻的涵(han)洞(dong)，從(cong)兩(liang)頭(tou)向結構的中心進(jin)行回填(tian);關于(yu)(yu)沒(mei)有(you)端部擋(dang)墻的涵(han)洞(dong)，從(cong)結構的中心向兩(liang)頭(tou)進(jin)行回填(tian)。

假如因偏土(tu)壓形(xing)成鋼(gang)波紋(wen)管變形(xing)時(shi)，應批改截面(mian)(mian)形(xing)象后(hou)重新壓實。涵洞是指在公路(lu)工(gong)程建設(she)中，為了使(shi)公路(lu)順利通(tong)過水渠不(bu)妨礙交通(tong)，設(she)于路(lu)基下(xia)修(xiu)筑于路(lu)面(mian)(mian)以下(xia)的(de)排水孔道(過水通(tong)道)，通(tong)過這種(zhong)結構可以讓水從(cong)公路(lu)的(de)下(xia)面(mian)(mian)流過。

用于跨越天然溝谷洼地排泄洪水，或橫跨大小路途作為人、畜和車輛的立交通道，或農田灌溉作為水渠。涵洞主要由洞身、基礎、端和翼墻等。涵洞是根據連通器的原理，常用磚、石、混凝土和鋼筋混凝土等資料筑成。一般孔徑較小，形狀有管形、箱形及拱形等。//hanihanbj.com/
