鋼波紋管從材料與(yu)結(jie)(jie)構和(he)功能的(de)(de)(de)本(ben)質關(guan)系上(shang)分析,選(xuan)用柔性(xing)高(gao)強度的(de)(de)(de)鋼(gang)波紋(wen)管洞因(yin)(yin)為軸向(xiang)波紋(wen)的(de)(de)(de)存在,使其具有(you)受力特征,軸向(xiang)和(he)徑向(xiang)同時分布(bu)因(yin)(yin)荷載引起的(de)(de)(de)應(ying)力應(ying)變,可以(yi)更(geng)大程度上(shang)渙散荷載的(de)(de)(de)應(ying)力會集,更(geng)好地發揮鋼(gang)結(jie)(jie)構的(de)(de)(de)優勢。
鋼波紋管經濟耐用的原因無人問津
鋼波(bo)(bo)紋(wen)管具(ju)有施工(gong)工(gong)期短、重量輕、安裝方(fang)便、耐久性能(neng)好、工(gong)程(cheng)造(zao)價低(di)、抗變形能(neng)力(li)強、減少維護(hu)費(fei)用成本等優點。鋼波(bo)(bo)紋(wen)管是一種柔(rou)性構造(zao),波(bo)(bo)紋(wen)管在構造(zao)上具(ju)有橫向抵償(chang)位移特性,可充分(fen)發揮鋼材抗拉功能(neng)強。
具有(you)較(jiao)大的抗變形和抗沉(chen)降才干,施(shi)工過程中(zhong)重量(liang)輕、設(she)備方便(bian)快捷、施(shi)工簡潔等許多優點(dian)。鋼(gang)波(bo)紋管按構成材(cai)料可分(fen)(fen)為(wei)金屬波(bo)紋管、非金屬波(bo)紋管兩種;按構造(zao)可分(fen)(fen)為(wei)單(dan)層(ceng)和多層(ceng)。單(dan)層(ceng)波(bo)紋管應(ying)用較(jiao)多。多層(ceng)波(bo)紋管強(qiang)度高(gao),耐(nai)久性好,應(ying)力小,用在重要(yao)的測量(liang)中(zhong)。
鋼(gang)波(bo)紋管的材料(liao)(liao)普通為青銅、黃銅、不(bu)銹鋼(gang)、蒙(meng)乃爾(er)合金和因康鎳爾(er)合金等。鋼(gang)波(bo)紋管選用規范(fan)化設計方(fang)案,出產制作,設計方(fang)案簡易,出產制作周期時間短(duan);工(gong)(gong)(gong)(gong)程(cheng)(cheng)項目具體(ti)工(gong)(gong)(gong)(gong)程(cheng)(cheng)造價(jia)比類似跨距(ju)的橋,洞低(di);工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)短(duan)工(gong)(gong)(gong)(gong)期,要害為組(zu)裝(zhuang)工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong);金屬材料(liao)(liao)波(bo)紋管替代混凝土結構展(zhan)開(kai)洞工(gong)(gong)(gong)(gong)程(cheng)(cheng)施工(gong)(gong)(gong)(gong)。
不(bu)(bu)管從工程施(shi)工周期時間(jian),工程施(shi)工工程造價,環(huan)境保護實際(ji)意義(yi)等層面都(dou)是有(you)其不(bu)(bu)能類比的優勢。鋼波(bo)紋管有(you)益于改(gai)善軟基處理,膨脹土,濕陷(xian)性等共同路基結構物(wu)處的不(bu)(bu)勻(yun)稱地基沉降(jiang)難題。
提升了道路服務項目特性,降低了工后保養成本費;降低了混凝土,塊塊石或砂礫石,砂等的使用量,有益于環境保護;沿海地區地表水多含有不一樣水平的腐蝕,別的山嶺重丘地域土層水流湍急,周期性降水沖刷比較嚴重。//hanihanbj.com/
