鋼波紋管，強度假設涵(han)洞(dong)(dong)(dong)(dong)設計方(fang)案得(de)很小(xiao)和太靠近(jin)于土層尤(you)其是(shi)在曝(pu)露的地區，而且水流速度遲緩(huan)，則在北邊(bian)地域的冬(dong)天十分簡略凍潔(jie)，后也要阻塞。這可以(yi)取(qu)得(de)搶救，辦法因而提高涵(han)洞(dong)(dong)(dong)(dong)的傾斜度，選用無底洞(dong)(dong)(dong)(dong)的木質涵(han)洞(dong)(dong)(dong)(dong)或(huo)在嚴寒時節靠近(jin)時，把涵(han)洞(dong)(dong)(dong)(dong)進(jin)口端用軟樹技鋪蓋。

The strength of steel corrugated pipe is assumed that the culvert design scheme is very small and too close to the soil layer, especially in the exposed area, and the water flow speed is slow, so it is very simple to freeze and clean in winter in the north area, and then it will be blocked. In this way, the inclination of the culvert can be increased, and the wooden culvert without bottom hole can be selected, or the entrance end of the culvert can be covered with soft tree technology when it is close in severe cold season.

假設涵洞的部位傾斜(xie)度(du)太低，那麼(ma)將被砂礫石頭(tou)和(he)粗粒砂等封堵(du)。這(zhe)類狀況可以依據在涵洞進口修(xiu)井或截水(shui)洼和(he)修(xiu)防止沖洗和(he)把(ba)水(shui)引入涵洞的中小型扶垛等對策來處(chu)理。當運用挖(wa)掘機(ji)和(he)其他(ta)超重型機(ji)器設備修(xiu)建路(lu)其和(he)排污溝時，鋪設金屬(shu)波紋管涵的土方開挖(wa)。

鋼波(bo)紋管(guan)(guan)涵鋪設(she)后的回(hui)填和由涵洞出入口把水導出去的泄排水溝的發掘等，一般來說(shuo)是(shi)選(xuan)用機械自動化工(gong)作的。卡(ka)(ka)箍加(jia)密封(feng)帶(dai)銜(xian)接(jie)便(bian)是(shi)用剖(pou)分的金(jin)屬(shu)卡(ka)(ka)箍將待銜(xian)接(jie)的兩(liang)(liang)個管(guan)(guan)段(duan)從外圓周(zhou)箍在(zai)一起。卡(ka)(ka)箍上做有凸(tu)起或彎邊，通過(guo)卡(ka)(ka)住(zhu)相(xiang)鄰(lin)的凸(tu)棱(leng)，可使(shi)待銜(xian)接(jie)的兩(liang)(liang)個鋼帶(dai)加(jia)強螺旋波(bo)紋管(guan)(guan)管(guan)(guan)段(duan)在(zai)軸向也被固定住(zhu)。

卡箍(gu)(gu)和管(guan)材(cai)之間加一層彈(dan)性(xing)密(mi)封(feng)(feng)帶(dai)，并在鋼帶(dai)加強聚乙(yi)烯(xi)螺(luo)旋(xuan)波紋管(guan)螺(luo)旋(xuan)槽的(de)(de)斷(duan)頭接(jie)(jie)縫兩頭塞上彈(dan)性(xing)密(mi)封(feng)(feng)塊，依(yi)托卡箍(gu)(gu)的(de)(de)鎖(suo)緊張力壓緊彈(dan)性(xing)密(mi)封(feng)(feng)帶(dai)和彈(dan)性(xing)密(mi)封(feng)(feng)塊來完成銜(xian)接(jie)(jie)的(de)(de)密(mi)封(feng)(feng)要求。該辦法的(de)(de)長處是(shi)：銜(xian)接(jie)(jie)便利靈敏、現場條(tiao)件適應性(xing)強、施(shi)工(gong)工(gong)具簡略（只需(xu)手(shou)藝工(gong)具）以及人工(gong)費(fei)用少。缺點是(shi)密(mi)封(feng)(feng)可靠性(xing)較(jiao)低，只適合用于排(pai)雨水管(guan)。

以便給環形管拱或拱起金屬波紋管涵而預備好一個潤滑床，要鋪平一層薄厚10cm上下的粗風化層或砂礫層，該層的原材料規定疏松些便于金屬波紋管涵可以淹沒于該層中。該潤滑床應具有3-5%繼續傾斜度，支撐金屬波紋管涵管道總長。回填應按6英寸一層給與夯實以結構加固對涵洞的側面合外力。//hanihanbj.com/
