當鋼波紋管處(chu)于軟(ruan)土地基(ji)上時,需對軟(ruan)土路基(ji)進行處(chu)理,然后(hou),在(zai)其上填一層大于20cm厚的砂礫墊層,并夯實緊密。施工(gong)(gong)(gong)便利(li):鋼波(bo)紋管是選(xuan)用套筒或法蘭方(fang)式(shi)銜(xian)接,并且能夠依據需求定(ding)制(zhi)長度,即便對錯熟練工(gong)(gong)(gong)也能夠操(cao)作(zuo),施工(gong)(gong)(gong)以(yi)少(shao)數(shu)的手(shou)工(gong)(gong)(gong)操(cao)作(zuo),可(ke)在(zai)短(duan)時間內完(wan)結,既快捷(jie)又(you)便利(li)。優(you)良的經濟性:銜(xian)接方(fang)式(shi)簡潔,可(ke)縮短(duan)工(gong)(gong)(gong)期。
鋼波紋管是怎樣連接的?有解說嗎?
根底應(ying)選(xuan)用(yong)(yong)(yong)振(zhen)動壓(ya)實機(ji)(ji)械進行(xing)分層碾壓(ya),壓(ya)實度(du)(du)不小于93%;管(guan)底楔形部(bu)分可選(xuan)用(yong)(yong)(yong)小型夯(hang)實機(ji)(ji)械斜向(xiang)夯(hang)實或選(xuan)用(yong)(yong)(yong)人工棒槌夯(hang)實;兩(liang)邊回(hui)填應(ying)對(dui)稱施工,分層回(hui)填,每層厚度(du)(du)不超(chao)越(yue)30cm;涵管(guan)兩(liang)邊及頂部(bu)壓(ya)實度(du)(du)與同一高程路基壓(ya)實度(du)(du)要(yao)求相同;涵管(guan)上方當回(hui)填土厚度(du)(du)超(chao)越(yue)30cm后,選(xuan)用(yong)(yong)(yong)壓(ya)路機(ji)(ji)靜壓(ya),超(chao)越(yue)50cm后,選(xuan)用(yong)(yong)(yong)壓(ya)路機(ji)(ji)振(zhen)壓(ya)。
運用(yong)壽命(ming)長,鋼波紋(wen)管(guan)是選用(yong)鋼管(guan)熱浸鍍鋅(xin),所以運用(yong)壽命(ming)長,壽命(ming)為80-100年,在腐蝕性(xing)特別大的環境下(xia)運用(yong)時,選用(yong)表里外表瀝清(qing)附層(ceng)的鋼波紋(wen)管(guan),可(ke)在原運用(yong)壽命(ming)根底上進步約(yue)20年以上。

強度(du)高(gao),因(yin)為其(qi)共(gong)同的(de)(de)波(bo)紋結(jie)構使其(qi)比(bi)同口(kou)徑的(de)(de)水(shui)泥管(guan)耐(nai)壓強度(du)大15倍以上。運送便利(li),鋼波(bo)紋管(guan)的(de)(de)重量只(zhi)有同口(kou)徑水(shui)泥管(guan)的(de)(de)1/10到1/5,即便在窄的(de)(de)場所沒有運送設備,人工(gong)(gong)也(ye)可運送。所需(xu)求的(de)(de)原料(liao)要有十分不錯的(de)(de)塑性,這樣有利(li)于鋼波(bo)紋管(guan)的(de)(de)彈性性能及加(jia)工(gong)(gong),并(bing)且(qie)隨著今后的(de)(de)加(jia)工(gong)(gong)處(chu)理獲(huo)得更高(gao)的(de)(de)彈性和所需(xu)求的(de)(de)強度(du)。
原料具有抗拉強度和疲勞強度,這樣完全能夠確保彈性的正常發揮。要有很強的焊。接才能,并且還要滿意焊。接所需求的要求。彈性是原料具有的主要原因,因為鋼波紋管常時間受時間和溫度的變化而影響著。//hanihanbj.com/
