鋼波紋管兩(liang)側不(bu)對(dui)稱(cheng)回填(tian)導致(zhi)鴨(ya)蛋圓(yuan),嚴重的導致(zhi)塌垮。楔(xie)形部回填(tian)不(bu)密實,導致(zhi)管體底(di)部變平。波紋涵(han)管兩(liang)側填(tian)土不(bu)密實,導致(zhi)變形過大。

這樣做鋼波紋管的防腐工作效果非常好

瀝青與煤油的(de)拌和(he)物涂(tu)料:涂(tu)料瀝青與煤油之配合(he)比為54: 46,使用(yong)此涂(tu)料時應涂(tu)刷(shua)2遍,使涂(tu)刷(shua)層總厚(hou)度達到(dao)0.4mm—0.5mm,涂(tu)刷(shua)用(yong)量0.6kg/m2。有條件時用(yong)噴(pen)槍噴(pen)涂(tu),效果更好,涂(tu)刷(shua)在(zai)廢水浸泡或常水位(wei)以下部分的(de)鋼波紋(wen)涵管(guan)。

一些個別(bie)的(de)小公司不注重(zhong)回填部分,因此波紋涵(han)管受到嚴重(zhong)損壞(huai),管身變形的(de)事情也偶(ou)爾(er)發生(sheng),下面簡單列舉五種情形,希望在施工過程中(zhong)加強管理(li),引起高度重(zhong)視:

體(ti)楔形(xing)(xing)部(bu)及兩(liang)側局部(bu)有大(da)石塊,導致局部(bu)波(bo)紋涵管有硬(ying)割傷或凸起。管體(ti)50cm內兩(liang)側回(hui)填(tian)材料(liao)達不到要求,應填(tian)沙性材料(liao),施工時卻(que)填(tian)筑了黃土(tu)、膨(peng)脹(zhang)土(tu)等(deng)材料(liao),遇水變軟,無承(cheng)載(zai)能力,導致管體(ti)橫向變形(xing)(xing)過大(da)。

鋼制波紋管涵

鋼波(bo)紋涵管(guan)(guan)是(shi)由鋼板制成(cheng)波(bo)形板后卷扎而成(cheng)或者拼裝而成(cheng)的(de)(de)(de)涵洞用(yong)(yong)(yong)(yong)管(guan)(guan),應(ying)(ying)用(yong)(yong)(yong)(yong)于公(gong)(gong)路(lu)、鐵(tie)路(lu)涵洞等工(gong)(gong)程,也可以(yi)(yi)半圓或其他曲(qu)線方式(shi)做(zuo)成(cheng)跨線通(tong)道(dao)(dao)、隧(sui)道(dao)(dao)和巷(xiang)道(dao)(dao)頂(ding)護。鋼波(bo)紋涵管(guan)(guan)沿管(guan)(guan)長方向(xiang)呈波(bo)形,有非常強的(de)(de)(de)適應(ying)(ying)縱向(xiang)變形能力(li),能避免因(yin)地(di)基不均勻沉降從而造成(cheng)破壞,在(zai)不增加材料用(yong)(yong)(yong)(yong)量的(de)(de)(de)情況下,可以(yi)(yi)將(jiang)管(guan)(guan)的(de)(de)(de)徑(jing)向(xiang)承載能力(li)提高數(shu)倍,由于其優越的(de)(de)(de)性能和適應(ying)(ying)能力(li)被國外用(yong)(yong)(yong)(yong)于公(gong)(gong)路(lu)工(gong)(gong)程、鐵(tie)路(lu)工(gong)(gong)程、礦(kuang)山(shan)巷(xiang)道(dao)(dao)、隧(sui)道(dao)(dao)工(gong)(gong)程、市政工(gong)(gong)程和軍事通(tong)道(dao)(dao)。國內使用(yong)(yong)(yong)(yong)推廣波(bo)紋涵管(guan)(guan)技術,是(shi)2000年(nian)(nian)以(yi)(yi)后由上海(hai)市公(gong)(gong)路(lu)管(guan)(guan)理(li)處、上海(hai)市政設計研究(jiu)院(yuan)、同濟(ji)大學、衡水益通(tong)公(gong)(gong)司等單位共同推動,2001-2006年(nian)(nian)在(zai)新(xin)疆、西藏、河北、山(shan)西、內蒙等省份多條高等級公(gong)(gong)路(lu)上應(ying)(ying)用(yong)(yong)(yong)(yong),用(yong)(yong)(yong)(yong)戶普遍反映良好。 

鋼波紋管力(li)學原理 鋼波(bo)(bo)紋管(guan)(guan)周圍土體(ti)在荷載作用(yong)下形成支撐,土體(ti)與(yu)波(bo)(bo)紋管(guan)(guan)形成一種組(zu)合結構,使(shi)(shi)波(bo)(bo)紋管(guan)(guan)能夠承受很(hen)大的(de)承載能力(li)。鋼波(bo)(bo)紋管(guan)(guan)沿直徑方向(xiang)(xiang)為(wei)圓形或拱(gong)(gong)(gong)形,而縱向(xiang)(xiang)又(you)是若干個小波(bo)(bo)紋拱(gong)(gong)(gong),縱橫組(zu)成雙曲拱(gong)(gong)(gong),與(yu)我國(guo)雙曲拱(gong)(gong)(gong)橋的(de)性質類似(si),由力(li)學可(ke)知,拱(gong)(gong)(gong)式在豎(shu)向(xiang)(xiang)荷載作用(yong)下,支撐處不僅產生(sheng)豎(shu)向(xiang)(xiang)反(fan)力(li),而且產生(sheng)水(shui)平(ping)推力(li),由于水(shui)平(ping)推力(li)的(de)存在,拱(gong)(gong)(gong)的(de)彎距(ju)將比相同跨徑的(de)梁或橋的(de)彎距(ju)小很(hen)多,而使(shi)(shi)整個拱(gong)(gong)(gong)主要承受壓(ya)力(li),波(bo)(bo)紋管(guan)(guan)涵四周有若干個支撐點,形成穩定的(de)承載能力(li)。

鋼波紋涵管價格

鋼波紋(wen)涵管(guan)應該涂涮兩遍(bian)瀝(li)青和(he)石油的拌(ban)和(he)物(wu),以加強(qiang)防(fang)腐蝕作用。從外(wai)觀看管(guan)壁內外(wai)均勻的涂成了黑管(guan)即可,但是必須要等(deng)到(dao)瀝(li)青晾干后方(fang)可安裝。瀝(li)青涂層的厚度保持在0.4—0.5mm內。

涂(tu)涮方法如下: 含有(you)石棉纖維的厚瀝(li)青涂(tu)料:涂(tu)料的溶劑是高質量的瀝(li)青,石棉粉的含量≥30%。噴(pen)涂(tu)方法可(ke)用(yong)氣壓(ya)噴(pen)涂(tu),或(huo)毛刷(shua)涂(tu)刷(shua),每次(ci)噴(pen)涂(tu)層(ceng)厚7mm—8mm,噴(pen)涂(tu)用(yong)量為lkg/m2左(zuo)右。被(bei)噴(pen)涂(tu)物表面應特別干(gan)爽(shuang),無油污。涂(tu)刷(shua)在廢水浸泡或(huo)常水位以下部分的鋼波紋涵管。
