為(wei)確(que)保鋼波紋管的(de)間距和順直，可用鋼(gang)筋支(zhi)架對波紋管(guan)進行點焊固(gu)定，防(fang)止澆筑砼(tong)時左右位移。管(guan)道鋪設后(hou)，出于(yu)其它原因形成管(guan)壁呈(cheng)現局(ju)部損壞(huai)，當損壞(huai)程(cheng)度比較小時，可通(tong)過焊槍修(xiu)補處理，如環向、縱(zong)向裂縫小于(yu)管(guan)周長的(de)112或孔徑60mm的(de)情況。

當(dang)損壞(huai)程度大于這些數據時(shi)，宜通過換波紋管或基修建檢查井、銜(xian)接井等(deng)修補(bu)辦法處(chu)理。現(xian)以1-5m鋼波紋管工(gong)(gong)程實例鋼波紋管工(gong)(gong)程施工(gong)(gong)工(gong)(gong)藝操控簡述如下。某高(gao)速公(gong)路因為工(gong)(gong)期較緊，考慮到原(yuan)規劃為1-2m石(shi)拱涵，而且其上有(you)高(gao)達(da)20m左右的涵頂填土。

When the damage degree is greater than these data, it should be repaired by replacing bellows or building inspection well and connecting well. Taking the 1-5m steel bellows project as an example, the construction technology of steel bellows project is described as follows. Due to the tight construction period of an expressway, considering that the original planning is 1-2m stone arch culvert, and there is about 20m of culvert top filling on it.

因為(wei)(wei)石拱涵施工(gong)進(jin)展(zhan)較慢(man)，為(wei)(wei)加(jia)速施工(gong)進(jin)展(zhan)，業主部(bu)分要求(qiu)將原規劃石拱涵改變規劃為(wei)(wei)1-5m鋼波紋(wen)(wen)管工(gong)程涵，以確保施工(gong)質量，加(jia)速工(gong)程建設進(jin)展(zhan)。波紋(wen)(wen)管涵為(wei)(wei)直(zhi)徑(jing)5m的組裝波紋(wen)(wen)管，全長110m，填方高度達20余米。

鋼波紋管

鋼波紋管是替換圓管涵、蓋板涵、拱涵和小橋的公路建材，該產品具有工期短、重量輕、設備利便、耐久性好、工程造價低、抗變形(xing)才能較強、削減(jian)通車后維護本錢等利益，特別應用在高寒凍土區域(yu)，軟土路基地帶和深(shen)填土地帶具有明顯的經濟效益。

雨期時節應留心防止管材漂浮、位移等現象，當管道設備結束沒有覆土遇到水泡情況時，應復測管底與管中心高程，并做好返工處理辦法。波紋管安頓和線盒及預留洞處相和諧，管線盒盡可能安頓在管間肋的位置。波紋管運工作面后，鋪放前應檢查管材的外形及管端的堵頭封堵是否緊密，對變形或裂口處進行修補。//hanihanbj.com/
