鋼波紋管在高寒凍土(tu)(tu)區(qu)域、軟土(tu)(tu)路基(ji)地帶,有很明(ming)顯(xian)的作用(yong),鋼(gang)波(bo)紋管(guan)有很好的路用(yong)性能,關(guan)于地基(ji)要求低(di),施工(gong)(gong)簡易,可以快(kuai)速安裝,可以很大程度縮短工(gong)(gong)期(qi),是普(pu)通涵(han)管(guan)沒辦法比(bi)較的,它在公路新改建工(gong)(gong)程和路基(ji)養護工(gong)(gong)程中發揮著很好的作用(yong),帶我們了解下你所不知(zhi)道的鋼(gang)波(bo)紋管(guan)的利益。
鋼波紋管涵價格根據什么來定價的?
鋼(gang)(gang)(gang)波(bo)紋管(guan)涵(han)具有著重(zhong)量輕、施工簡(jian)易、工期(qi)短等利益,鋼(gang)(gang)(gang)波(bo)紋管(guan)涵(han)的(de)底(di)端及兩頭可填充砂礫、碎石(shi)土、片(pian)(pian)石(shi)砼等原材(cai)料,鋼(gang)(gang)(gang)波(bo)紋管(guan)涵(han)頂端能用(yong)高壓(ya)水泵運送脹(zhang)大水泥砂漿(jiang)或(huo)者(zhe)砌墻片(pian)(pian)石(shi)脹(zhang)大砼,這種方法在舊橋(qiao)梁工程(cheng)加固中(zhong)獲(huo)得(de)了很(hen)好的(de)效(xiao)果。因為(wei)鋼(gang)(gang)(gang)波(bo)紋管(guan)涵(han)結構中(zhong)空(kong),在保持(chi)剛度(du)的(de)前提下,節約質料。
相同(tong)直(zhi)徑下,單位長度重(zhong)量是水(shui)泥(ni)管(guan)重(zhong)量的1/8,施(shi)工(gong)(gong)(gong)便利,不(bu)需要大(da)型安(an)裝(zhuang)設備,減輕了(le)(le)勞(lao)動強度,縮(suo)短了(le)(le)施(shi)工(gong)(gong)(gong)工(gong)(gong)(gong)期。不(bu)被污水(shui)、廢水(shui)及(ji)化學藥品腐(fu)蝕,不(bu)被土(tu)壤中腐(fu)爛的物(wu)質(zhi)腐(fu)蝕。管(guan)材質(zhi)料價格低,施(shi)工(gong)(gong)(gong)、管(guan)理、維護費用(yong)低。管(guan)壁為“工(gong)(gong)(gong)”字結構,耐沖擊,高剛性(xing);中空壁纏(chan)繞管(guan)屬柔性(xing)管(guan),延伸性(xing)好(hao),地基下沉管(guan)材也不(bu)會決裂。
存放鋼波紋管(guan)涵的(de)(de)場地(di)應(ying)該平整(zheng)、遠(yuan)離熱源,堆(dui)積(ji)(ji)時,兩邊(bian)用(yong)木楔和(he)木板(ban)擋住,避免滑動(dong);管(guan)材(cai)(cai)堆(dui)積(ji)(ji)高度要(yao)嚴厲依照(zhao)CJ/T270-2007的(de)(de)要(yao)求(qiu)履行(xing),不(bu)得超越3米(mi);不(bu)同直(zhi)徑(jing)與不(bu)同環剛(gang)度等級的(de)(de)管(guan)材(cai)(cai)宜(yi)分類堆(dui)積(ji)(ji);假如長期堆(dui)積(ji)(ji)的(de)(de)話,為(wei)避免陽光直(zhi)射和(he)暴曬應(ying)遮蓋好;橡膠套、螺栓、不(bu)銹鋼套等宜(yi)放在(zai)(zai)倉庫存貯;在(zai)(zai)管(guan)道安裝(zhuang)現場,管(guan)材(cai)(cai)堆(dui)積(ji)(ji)應(ying)避免阻礙交(jiao)通(tong)。
鋼波(bo)紋管(guan)涵裝(zhuang)卸時,謹防(fang)管(guan)材(cai)(cai)拋落、彼此(ci)碰擊(ji);小口徑、較輕(qing)管(guan)材(cai)(cai)可人工裝(zhuang)卸,大口徑、重管(guan)材(cai)(cai)應采用(yong)機械吊(diao)(diao)裝(zhuang);裝(zhuang)卸時要選用(yong)柔性軟質的(de)(de)、較寬的(de)(de)尼龍吊(diao)(diao)帶或(huo)繩作為吊(diao)(diao)索,不得(de)用(yong)鋼絲繩或(huo)鐵鏈直接(jie)接(jie)觸(chu)吊(diao)(diao)裝(zhuang)管(guan)材(cai)(cai);管(guan)材(cai)(cai)的(de)(de)起(qi)吊(diao)(diao)宜采用(yong)兩(liang)個吊(diao)(diao)點(dian)(dian)(dian)起(qi)吊(diao)(diao),嚴禁穿心吊(diao)(diao),吊(diao)(diao)點(dian)(dian)(dian)間隔(ge)應契合的(de)(de)要求(qiu),即管(guan)材(cai)(cai)上(shang)兩(liang)吊(diao)(diao)點(dian)(dian)(dian)應在間隔(ge)管(guan)兩(liang)端約1/4管(guan)利益。
移動或裝卸管材時不得造成其它管材移位或翻滾。運送鋼波紋管涵時,與管材接觸處的車底、船底要盡量平坦,避免翻滾和相互磕碰的辦法,不得接觸尖利尖利物體,避免劃傷管材;發運的管材應做好管材端口的保護;大口徑管材運送時,宜在管側嵌入楔保護;不同直徑的管材同車運送時,應將大直徑管材放在下面;管材在運送車上的堆積高度要契合交通管理條例的規則。//hanihanbj.com/
