鋼波紋(wen)管(guan)使(shi)用(yong)壽(shou)(shou)命(ming)長,是選用(yong)鋼管熱浸鍍鋅,所以(yi)使(shi)用(yong)壽(shou)(shou)命(ming)長,壽(shou)(shou)命(ming)為80-100年,在腐蝕性特(te)別大(da)的(de)環(huan)境下使(shi)用(yong)時,選用(yong)表里外表瀝清附層的(de)鋼波紋管,可在原使(shi)用(yong)壽(shou)(shou)命(ming)基礎上提(ti)高(gao)約20年以(yi)上。
鋼波紋管嘆為觀止的原因
施工(gong)(gong)方(fang)(fang)便(bian)(bian)(bian):鋼波紋管涵是選用套(tao)筒或法蘭辦法銜接,而且能(neng)夠根(gen)據需要定(ding)長度,即便(bian)(bian)(bian)是非(fei)熟練工(gong)(gong)也能(neng)夠操(cao)作,施工(gong)(gong)以少數的手工(gong)(gong)操(cao)作,可在短(duan)時間內完(wan)成,既方(fang)(fang)便(bian)(bian)(bian)又方(fang)(fang)便(bian)(bian)(bian)。經濟(ji)性:銜接辦法簡便(bian)(bian)(bian),可縮(suo)短(duan)工(gong)(gong)期。
波紋涵(han)管用(yong)(yong)(yong)洛(luo)氏(shi)硬(ying)度(du)(du)(du)(du)計能夠丈(zhang)量從軟到硬(ying)的(de)(de)各種(zhong)不(bu)同材料,這是(shi)因為它選用(yong)(yong)(yong)了不(bu)同的(de)(de)壓(ya)頭(tou)和載荷,組成(cheng)各種(zhong)不(bu)同的(de)(de)洛(luo)氏(shi)硬(ying)度(du)(du)(du)(du)標尺,如(ru)HRA、HRB、HRC等(deng)。一般出(chu)產以HRC(用(yong)(yong)(yong)120度(du)(du)(du)(du)金剛石(shi)圓錐體作壓(ya)頭(tou),載荷為1500N)用(yong)(yong)(yong)得多,波紋涵(han)管硬(ying)度(du)(du)(du)(du)值的(de)(de)標注辦(ban)法與布(bu)氏(shi)硬(ying)度(du)(du)(du)(du)相同,硬(ying)度(du)(du)(du)(du)值的(de)(de)有用(yong)(yong)(yong)規模為20~70HRC。為保證中心不(bu)留空地,應在兩接頭(tou)端頭(tou)處(chu)做好符號(hao)。做好后要用(yong)(yong)(yong)膠帶包裹(guo)緊密,以防漏漿。
1.搬運到現(xian)場的鋼(gang)(gang)波(bo)紋管要會(hui)集堆積整(zheng)齊,不(bu)能在鋼(gang)(gang)波(bo)紋管上踐踏(ta)。
2.鋼波紋(wen)管要掩蓋維護(hu),避免風吹雨(yu)淋使其提早老化。
3.切開鋼波紋管(guan)要平直(zhi),不能切成(cheng)斜口。
4.鋼(gang)(gang)波紋(wen)管接頭的(de)辦法:鋼(gang)(gang)波紋(wen)管接頭處要(yao)(yao)外包0.3米長的(de)大(da)號(hao)鋼(gang)(gang)波紋(wen)管,而且兩端頭要(yao)(yao)對半擰緊,中心不(bu)得留(liu)有空地(di)。
5.鋼波紋管方位定位要,尤其是靠近接頭的部位,鋼波紋管定位鋼筋間距為0.5米,不能短少。//hanihanbj.com/
