鋼波紋管兩(liang)側不對稱(cheng)回(hui)填(tian)導致(zhi)(zhi)鴨(ya)蛋圓,嚴重的導致(zhi)(zhi)塌垮(kua)。楔形部(bu)回(hui)填(tian)不密實,導致(zhi)(zhi)管體底部(bu)變平。波紋涵管兩(liang)側填(tian)土不密實,導致(zhi)(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(yu)煤油(you)的(de)拌和(he)物涂(tu)(tu)料(liao):涂(tu)(tu)料(liao)瀝青與(yu)煤油(you)之配(pei)合比為54: 46,使(shi)用(yong)(yong)此涂(tu)(tu)料(liao)時應涂(tu)(tu)刷(shua)2遍,使(shi)涂(tu)(tu)刷(shua)層(ceng)總厚度達到0.4mm—0.5mm,涂(tu)(tu)刷(shua)用(yong)(yong)量0.6kg/m2。有(you)條件時用(yong)(yong)噴(pen)槍噴(pen)涂(tu)(tu),效果(guo)更好,涂(tu)(tu)刷(shua)在廢水(shui)(shui)浸泡或常水(shui)(shui)位以下部分(fen)的(de)鋼波紋(wen)涵(han)管。

一些(xie)個(ge)別(bie)的(de)小公司(si)不注重回填部分,因此波紋涵(han)管受到嚴(yan)重損(sun)壞,管身變形的(de)事(shi)情(qing)也偶爾發生,下面簡單列舉五(wu)種情(qing)形,希(xi)望(wang)在施工(gong)過(guo)程中加(jia)強管理,引(yin)起高度重視:

體(ti)楔形(xing)(xing)部(bu)及兩側局部(bu)有大石塊,導致局部(bu)波(bo)紋涵管有硬割(ge)傷或凸起。管體(ti)50cm內兩側回填(tian)(tian)材(cai)料達不到要(yao)求,應填(tian)(tian)沙性材(cai)料,施(shi)工時(shi)卻填(tian)(tian)筑了黃(huang)土、膨脹土等(deng)材(cai)料,遇水(shui)變(bian)軟,無承載能(neng)力(li),導致管體(ti)橫向變(bian)形(xing)(xing)過大。

鋼制波紋管涵

鋼(gang)波(bo)紋涵(han)(han)管(guan)(guan)是由鋼(gang)板制成(cheng)波(bo)形(xing)板后卷(juan)扎(zha)而成(cheng)或者(zhe)拼(pin)裝而成(cheng)的(de)涵(han)(han)洞用(yong)管(guan)(guan),應用(yong)于公路(lu)(lu)、鐵(tie)路(lu)(lu)涵(han)(han)洞等(deng)工(gong)(gong)程(cheng)(cheng),也可(ke)以半圓或其他曲線方式做成(cheng)跨(kua)線通道、隧道和巷(xiang)道頂護。鋼(gang)波(bo)紋涵(han)(han)管(guan)(guan)沿管(guan)(guan)長方向(xiang)呈波(bo)形(xing),有非常強的(de)適(shi)應縱向(xiang)變形(xing)能力,能避免因(yin)地(di)基不均勻沉降從(cong)而造(zao)成(cheng)破(po)壞,在不增(zeng)加材料(liao)用(yong)量的(de)情(qing)況(kuang)下,可(ke)以將管(guan)(guan)的(de)徑向(xiang)承載(zai)能力提高數倍(bei),由于其優越(yue)的(de)性(xing)能和適(shi)應能力被國(guo)外用(yong)于公路(lu)(lu)工(gong)(gong)程(cheng)(cheng)、鐵(tie)路(lu)(lu)工(gong)(gong)程(cheng)(cheng)、礦山(shan)巷(xiang)道、隧道工(gong)(gong)程(cheng)(cheng)、市政(zheng)工(gong)(gong)程(cheng)(cheng)和軍事通道。國(guo)內(nei)使(shi)用(yong)推廣波(bo)紋涵(han)(han)管(guan)(guan)技術(shu),是2000年以后由上(shang)海市公路(lu)(lu)管(guan)(guan)理處、上(shang)海市政(zheng)設計研究院、同濟大學、衡(heng)水益通公司等(deng)單(dan)位共同推動,2001-2006年在新疆、西藏、河北(bei)、山(shan)西、內(nei)蒙等(deng)省份(fen)多條高等(deng)級公路(lu)(lu)上(shang)應用(yong),用(yong)戶(hu)普遍(bian)反映(ying)良好(hao)。 

鋼波紋管力(li)(li)學原理 鋼波(bo)紋(wen)(wen)管(guan)周圍(wei)土體在荷載(zai)作用(yong)下(xia)形(xing)成支(zhi)撐(cheng),土體與(yu)波(bo)紋(wen)(wen)管(guan)形(xing)成一種組合結構,使(shi)波(bo)紋(wen)(wen)管(guan)能夠承(cheng)受很大的(de)承(cheng)載(zai)能力(li)(li)。鋼波(bo)紋(wen)(wen)管(guan)沿直徑方向為圓(yuan)形(xing)或拱(gong)(gong)(gong)形(xing),而縱(zong)向又(you)是若干(gan)個(ge)小波(bo)紋(wen)(wen)拱(gong)(gong)(gong),縱(zong)橫組成雙(shuang)曲拱(gong)(gong)(gong),與(yu)我(wo)國雙(shuang)曲拱(gong)(gong)(gong)橋的(de)性質類似,由力(li)(li)學可知,拱(gong)(gong)(gong)式在豎(shu)向荷載(zai)作用(yong)下(xia),支(zhi)撐(cheng)處不僅產生(sheng)豎(shu)向反力(li)(li),而且產生(sheng)水平推力(li)(li),由于水平推力(li)(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)小很多(duo),而使(shi)整個(ge)拱(gong)(gong)(gong)主要承(cheng)受壓力(li)(li),波(bo)紋(wen)(wen)管(guan)涵(han)四周有若干(gan)個(ge)支(zhi)撐(cheng)點,形(xing)成穩定的(de)承(cheng)載(zai)能力(li)(li)。

鋼波紋涵管價格

鋼波(bo)紋涵管(guan)(guan)應(ying)該(gai)涂(tu)涮兩遍瀝(li)青和石油的拌和物,以(yi)加強防腐蝕(shi)作用。從(cong)外(wai)(wai)觀看(kan)管(guan)(guan)壁(bi)內外(wai)(wai)均勻的涂(tu)成了黑(hei)管(guan)(guan)即可(ke),但是必(bi)須要等到(dao)瀝(li)青晾干后方可(ke)安裝。瀝(li)青涂(tu)層(ceng)的厚(hou)度保持在0.4—0.5mm內。

涂(tu)涮方法如下(xia)(xia): 含有石(shi)棉(mian)(mian)纖維(wei)的(de)厚瀝青涂(tu)料:涂(tu)料的(de)溶(rong)劑是高質量(liang)(liang)的(de)瀝青,石(shi)棉(mian)(mian)粉的(de)含量(liang)(liang)≥30%。噴涂(tu)方法可用氣壓噴涂(tu),或毛刷(shua)(shua)涂(tu)刷(shua)(shua),每(mei)次(ci)噴涂(tu)層厚7mm—8mm,噴涂(tu)用量(liang)(liang)為lkg/m2左(zuo)右。被(bei)噴涂(tu)物(wu)表面應特別干(gan)爽,無油污。涂(tu)刷(shua)(shua)在廢(fei)水(shui)浸泡或常水(shui)位以下(xia)(xia)部分的(de)鋼(gang)波紋涵管。
