金(jin)屬波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)也叫金(jin)屬波(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)、波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan)涵(han)(han)、波(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan)或鋼(gang)制(zhi)波(bo)(bo)(bo)(bo)紋(wen)涵(han)(han)管(guan)(guan)(guan),是(shi)指鋪(pu)埋在公(gong)路,鐵(tie)路下面的涵(han)(han)洞(dong)用螺紋(wen)波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan),它是(shi)由波(bo)(bo)(bo)(bo)形(xing)金(jin)屬板卷制(zhi)成(cheng)或用半圓波(bo)(bo)(bo)(bo)形(xing)鋼(gang)片拼制(zhi)成(cheng)的圓形(xing)波(bo)(bo)(bo)(bo)紋(wen)管(guan)(guan)(guan),應用于公(gong)路,鐵(tie)路,小橋,通道(dao),擋土(tu)墻以及各(ge)種礦(kuang)場,巷道(dao)擋墻支護等工程中(zhong)的涵(han)(han)洞(dong)(管(guan)(guan)(guan))。
①強度(du)高,由于其(qi)獨特的波紋結(jie)構(gou)使其(qi)比同口徑的水泥管(guan)耐壓強度(du)大15倍以(yi)上。
②運(yun)輸方便,波紋管涵的重量只有同口(kou)徑水泥管的1/10到1/5,即使(shi)在窄的場所沒有運(yun)輸設備(bei),人工也(ye)可運(yun)輸。
③使(shi)(shi)用(yong)(yong)(yong)壽命長(chang),鋼制(zhi)波紋管(guan)(guan)涵是采(cai)用(yong)(yong)(yong)鋼管(guan)(guan)熱浸鍍鋅,所以(yi)使(shi)(shi)用(yong)(yong)(yong)壽命長(chang),壽命為(wei)80-100年,在腐蝕性特(te)別大(da)的(de)環境下(xia)使(shi)(shi)用(yong)(yong)(yong)時,采(cai)用(yong)(yong)(yong)內外表(biao)面瀝清(qing)附層(ceng)的(de)鋼制(zhi)波紋管(guan)(guan),可在原(yuan)使(shi)(shi)用(yong)(yong)(yong)壽命基(ji)礎上(shang)提高約(yue)20年以(yi)上(shang)。
④ 施(shi)工(gong)方(fang)便:波紋管涵是(shi)采用套(tao)筒或法蘭(lan)方(fang)式(shi)連接(jie),而且可以(yi)(yi)根(gen)據(ju)需要定制(zhi)長度,即使是(shi)非熟(shu)練工(gong)也(ye)可以(yi)(yi)操作,施(shi)工(gong)以(yi)(yi)少量的手工(gong)操作,可在短時間(jian)內完成,既快捷又方(fang)便。
⑤優良(liang)的經(jing)濟性(xing):連(lian)接方式簡便,可縮短工(gong)期。
