鋼波紋管兩(liang)側不對稱回填導(dao)(dao)致(zhi)(zhi)鴨蛋(dan)圓,嚴(yan)重(zhong)的導(dao)(dao)致(zhi)(zhi)塌垮(kua)。楔(xie)形部回填不密實(shi),導(dao)(dao)致(zhi)(zhi)管體底部變(bian)平。波紋涵管兩(liang)側填土不密實(shi),導(dao)(dao)致(zhi)(zhi)變(bian)形過大。

這樣做鋼波紋管的防腐工作效果非常好

瀝青與(yu)煤油的拌和物涂(tu)(tu)(tu)(tu)料(liao):涂(tu)(tu)(tu)(tu)料(liao)瀝青與(yu)煤油之配合比為54: 46,使(shi)用此涂(tu)(tu)(tu)(tu)料(liao)時應涂(tu)(tu)(tu)(tu)刷(shua)2遍,使(shi)涂(tu)(tu)(tu)(tu)刷(shua)層總(zong)厚度(du)達到(dao)0.4mm—0.5mm,涂(tu)(tu)(tu)(tu)刷(shua)用量0.6kg/m2。有(you)條件時用噴槍噴涂(tu)(tu)(tu)(tu),效(xiao)果(guo)更好,涂(tu)(tu)(tu)(tu)刷(shua)在廢水浸泡或常水位以下部分的鋼(gang)波紋涵管。

一些個別的小公司不注重(zhong)回填部分,因(yin)此波紋涵管受到(dao)嚴重(zhong)損壞,管身變形的事情(qing)也偶(ou)爾發(fa)生,下(xia)面簡(jian)單列舉五種情(qing)形,希望在施工(gong)過程中加強管理,引起高度重(zhong)視:

體(ti)楔形(xing)(xing)部(bu)及兩側(ce)局部(bu)有(you)(you)大石(shi)塊,導致(zhi)局部(bu)波(bo)紋涵(han)管有(you)(you)硬割傷(shang)或凸起(qi)。管體(ti)50cm內(nei)兩側(ce)回填(tian)材(cai)料達不(bu)到(dao)要求,應填(tian)沙性(xing)材(cai)料,施工(gong)時(shi)卻填(tian)筑(zhu)了(le)黃土、膨(peng)脹土等材(cai)料,遇(yu)水變軟,無(wu)承載能力(li),導致(zhi)管體(ti)橫向變形(xing)(xing)過大。

鋼制波紋管涵

鋼波紋(wen)涵(han)管(guan)是由(you)鋼板制成(cheng)(cheng)波形(xing)板后(hou)卷扎而成(cheng)(cheng)或(huo)者拼裝(zhuang)而成(cheng)(cheng)的(de)涵(han)洞用(yong)管(guan),應(ying)用(yong)于(yu)公(gong)(gong)路(lu)、鐵路(lu)涵(han)洞等(deng)工(gong)程(cheng),也(ye)可(ke)以半(ban)圓或(huo)其他曲線方式(shi)做成(cheng)(cheng)跨線通(tong)道(dao)、隧道(dao)和巷道(dao)頂護。鋼波紋(wen)涵(han)管(guan)沿管(guan)長(chang)方向(xiang)呈波形(xing),有非常強(qiang)的(de)適應(ying)縱向(xiang)變(bian)形(xing)能力(li),能避免因地基不均勻沉降(jiang)從而造成(cheng)(cheng)破(po)壞(huai),在(zai)不增加材料用(yong)量的(de)情(qing)況下,可(ke)以將管(guan)的(de)徑(jing)向(xiang)承載能力(li)提高數倍,由(you)于(yu)其優(you)越(yue)的(de)性能和適應(ying)能力(li)被國(guo)(guo)外用(yong)于(yu)公(gong)(gong)路(lu)工(gong)程(cheng)、鐵路(lu)工(gong)程(cheng)、礦山巷道(dao)、隧道(dao)工(gong)程(cheng)、市政(zheng)工(gong)程(cheng)和軍事通(tong)道(dao)。國(guo)(guo)內使用(yong)推(tui)廣波紋(wen)涵(han)管(guan)技術,是2000年以后(hou)由(you)上海市公(gong)(gong)路(lu)管(guan)理處、上海市政(zheng)設(she)計(ji)研(yan)究院(yuan)、同濟大學、衡水(shui)益通(tong)公(gong)(gong)司等(deng)單位共同推(tui)動(dong),2001-2006年在(zai)新疆、西(xi)藏、河北、山西(xi)、內蒙等(deng)省份多(duo)條高等(deng)級(ji)公(gong)(gong)路(lu)上應(ying)用(yong),用(yong)戶普(pu)遍反映良(liang)好。 

鋼波紋管力(li)(li)(li)學原理 鋼波(bo)(bo)紋(wen)管(guan)周(zhou)圍(wei)土體(ti)在(zai)荷(he)載(zai)作用下形(xing)(xing)(xing)成(cheng)支撐,土體(ti)與波(bo)(bo)紋(wen)管(guan)形(xing)(xing)(xing)成(cheng)一種組合(he)結(jie)構(gou),使(shi)波(bo)(bo)紋(wen)管(guan)能夠承(cheng)受很大的(de)承(cheng)載(zai)能力(li)(li)(li)。鋼波(bo)(bo)紋(wen)管(guan)沿直徑方向(xiang)(xiang)為圓形(xing)(xing)(xing)或(huo)拱(gong)(gong)形(xing)(xing)(xing),而縱(zong)向(xiang)(xiang)又(you)是若干個小波(bo)(bo)紋(wen)拱(gong)(gong),縱(zong)橫組成(cheng)雙曲拱(gong)(gong),與我國(guo)雙曲拱(gong)(gong)橋(qiao)(qiao)的(de)性質類(lei)似,由力(li)(li)(li)學可知,拱(gong)(gong)式在(zai)豎向(xiang)(xiang)荷(he)載(zai)作用下,支撐處不僅產生(sheng)豎向(xiang)(xiang)反力(li)(li)(li),而且(qie)產生(sheng)水平(ping)推力(li)(li)(li),由于水平(ping)推力(li)(li)(li)的(de)存在(zai),拱(gong)(gong)的(de)彎距將比(bi)相同跨徑的(de)梁或(huo)橋(qiao)(qiao)的(de)彎距小很多,而使(shi)整個拱(gong)(gong)主要承(cheng)受壓力(li)(li)(li),波(bo)(bo)紋(wen)管(guan)涵四周(zhou)有(you)若干個支撐點,形(xing)(xing)(xing)成(cheng)穩(wen)定的(de)承(cheng)載(zai)能力(li)(li)(li)。

鋼波紋涵管價格

鋼(gang)波(bo)紋涵(han)管應該涂涮兩遍瀝青(qing)和(he)石油的拌和(he)物(wu),以加強(qiang)防腐蝕作用。從外(wai)觀看管壁內外(wai)均勻的涂成(cheng)了黑(hei)管即可,但是必須要等到瀝青(qing)晾干后方可安(an)裝。瀝青(qing)涂層的厚度(du)保持在0.4—0.5mm內。

涂(tu)涮方(fang)法如下: 含(han)有石(shi)棉(mian)纖維的(de)厚瀝青涂(tu)料:涂(tu)料的(de)溶劑是(shi)高質量的(de)瀝青,石(shi)棉(mian)粉的(de)含(han)量≥30%。噴(pen)(pen)涂(tu)方(fang)法可用氣壓噴(pen)(pen)涂(tu),或(huo)毛刷涂(tu)刷,每(mei)次噴(pen)(pen)涂(tu)層厚7mm—8mm,噴(pen)(pen)涂(tu)用量為lkg/m2左右(you)。被噴(pen)(pen)涂(tu)物表(biao)面應特(te)別干爽(shuang),無油污。涂(tu)刷在廢水浸泡或(huo)常水位以下部分的(de)鋼波紋涵管。
