鋼波紋(wen)管使(shi)(shi)(shi)用(yong)壽命(ming)(ming)長,是選用(yong)鋼管(guan)熱浸鍍鋅,所以(yi)使(shi)(shi)(shi)用(yong)壽命(ming)(ming)長,壽命(ming)(ming)為(wei)80-100年(nian),在腐蝕性特(te)別大(da)的環(huan)境下使(shi)(shi)(shi)用(yong)時,選用(yong)表里外表瀝清(qing)附層的鋼波紋管(guan),可在原使(shi)(shi)(shi)用(yong)壽命(ming)(ming)基礎上提(ti)高約20年(nian)以(yi)上。
鋼波紋管嘆為觀止的原因
施工(gong)方(fang)(fang)便:鋼(gang)波紋管涵是選用套筒或法蘭辦法銜接,而且能(neng)夠根據(ju)需要定長(chang)度,即便是非(fei)熟練(lian)工(gong)也能(neng)夠操(cao)作(zuo),施工(gong)以少數的手工(gong)操(cao)作(zuo),可在(zai)短時間內完成,既方(fang)(fang)便又方(fang)(fang)便。經濟性:銜接辦法簡便,可縮短工(gong)期。
波紋涵管用(yong)(yong)(yong)(yong)洛(luo)氏硬度(du)(du)計(ji)能夠丈(zhang)量從軟到(dao)硬的(de)各種不同(tong)(tong)材料,這是因(yin)為它選用(yong)(yong)(yong)(yong)了不同(tong)(tong)的(de)壓頭和載荷,組成各種不同(tong)(tong)的(de)洛(luo)氏硬度(du)(du)標尺,如(ru)HRA、HRB、HRC等。一般出產以(yi)HRC(用(yong)(yong)(yong)(yong)120度(du)(du)金剛石圓(yuan)錐(zhui)體作壓頭,載荷為1500N)用(yong)(yong)(yong)(yong)得多,波紋涵管硬度(du)(du)值的(de)標注(zhu)辦(ban)法與布氏硬度(du)(du)相同(tong)(tong),硬度(du)(du)值的(de)有(you)用(yong)(yong)(yong)(yong)規模為20~70HRC。為保證中心(xin)不留空地,應在(zai)兩接(jie)頭端頭處做好(hao)符號。做好(hao)后要用(yong)(yong)(yong)(yong)膠帶包裹緊密,以(yi)防漏漿。
1.搬運到現(xian)場的鋼波(bo)紋(wen)管(guan)要會集堆積整(zheng)齊(qi),不能在鋼波(bo)紋(wen)管(guan)上踐(jian)踏。
2.鋼波紋管要掩蓋維護,避免(mian)風吹雨淋使其提早老(lao)化(hua)。
3.切(qie)開鋼波紋管要(yao)平直(zhi),不能切(qie)成斜口。
4.鋼波(bo)紋(wen)管(guan)接頭(tou)的(de)辦法:鋼波(bo)紋(wen)管(guan)接頭(tou)處(chu)要(yao)外(wai)包0.3米長的(de)大(da)號鋼波(bo)紋(wen)管(guan),而且兩(liang)端(duan)頭(tou)要(yao)對半(ban)擰緊,中心(xin)不(bu)得留有空地。
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/
