鋼波紋管的用(yong)途越來(lai)越廣發，已經不再(zai)(zai)是大家(jia)所知道的只能(neng)用(yong)在公路(lu)排水系統，我們出產的波(bo)(bo)紋涵管(guan)還可作(zuo)為(wei)冷庫中透(tou)(tou)風系統的通道，無(wu)論是蘊藏(zang)蔬(shu)菜，冷飲(yin)，仍是肉(rou)類(lei)，水產，再(zai)(zai)也不用(yong)擔心(xin)腐爛題目，有(you)了(le)波(bo)(bo)紋涵管(guan)透(tou)(tou)風，散熱，保證空氣的暢通流暢，那都是小菜一碟。

其實鋼波紋管還能開發出一些新的使用途徑

檢(jian)修評(ping)定(ding)通過對已建(jian)成(cheng)的鋼波紋涵管(guan)進行質量(liang)檢(jian)查發現,管(guan)座墊層混(hun)凝土(tu)強度知(zhi)足(zu)混(hun)凝土(tu)抗壓(ya)評(ping)定(ding),墊層寬度及厚(hou)度知(zhi)足(zu)設計要求,相鄰管(guan)節(jie)底面錯(cuo)臺也均知(zhi)足(zu)要求;外觀管(guan)壁豎(shu)直,接縫(feng)平整(zheng),填縫(feng)豐滿(man),施工(gong)質量(liang)合(he)格。

護(hu)(hu)坡(po)防(fang)護(hu)(hu)洞口設(she)計采(cai)用端墻形(xing)式。洞口鋪砌(qi)及護(hu)(hu)坡(po)防(fang)護(hu)(hu)為M7.5漿(jiang)砌(qi)片(pian)石(shi)(shi),應選(xuan)擇(ze)幾何尺寸相對長和短的(de)石(shi)(shi)塊交錯在統一層使(shi)之形(xing)成(cheng)錯鎖結(jie)構,保證錯縫砌(qi)筑,不(bu)得泛起豎縫、通縫。外露面(mian)要選(xuan)擇(ze)石(shi)(shi)塊質(zhi)地適當,細致光彩平均(jun),無風化(hua)剝落(luo)無裂紋的(de)大石(shi)(shi)塊進行(xing)鑿(zao)面(mian)鑿(zao)紋,以(yi)確保工程外露面(mian)的(de)平整(zheng)和正確的(de)幾何尺寸,輪廓要求清楚,線條直順(shun)柔(rou)美,并(bing)勾凹縫。

填筑必需在鋼波紋管兩(liang)(liang)側同步對(dui)稱進(jin)行,兩(liang)(liang)側的回填(tian)(tian)土(tu)高差以不(bu)超過兩(liang)(liang)側土(tu)為(wei)宜。涵洞上方回填(tian)(tian)厚度小于(yu)(yu)50cm時采(cai)用(yong)(yong)手扶振(zhen)動壓路機(ji)壓實或用(yong)(yong)小于(yu)(yu)6t的靜碾壓路機(ji)壓實,壓實度不(bu)小于(yu)(yu)95%。當通道(dao)頂(ding)填(tian)(tian)土(tu)大于(yu)(yu)50cm后,方可(ke)采(cai)用(yong)(yong)YZ20壓路機(ji)施工(gong),每層厚度20cm,壓實度不(bu)小于(yu)(yu)95%。

涵背兩側的部(bu)位回填(tian)(tian)(tian)采用級配良好的自然砂(sha)礫或粗砂(sha),使(shi)用小型(xing)夯實機械夯實。填(tian)(tian)(tian)筑時應分層(ceng)(ceng)(ceng)填(tian)(tian)(tian)筑、分層(ceng)(ceng)(ceng)壓實,松鋪厚度(du)為15cm,壓實度(du)要求(qiu)達到96%方可進行下層(ceng)(ceng)(ceng)填(tian)(tian)(tian)筑。填(tian)(tian)(tian)筑前在(zai)管節兩側用紅色油(you)漆(qi)按(an)每15m高度(du)標注(zhu),填(tian)(tian)(tian)筑時按(an)標注(zhu)線控(kong)制。

為(wei)(wei)保(bao)證管(guan)(guan)底的(de)回(hui)填質量,管(guan)(guan)底楔形塊處(chu)的(de)填筑(zhu)材料(liao)采用(yong)級配良好的(de)自然砂(sha)礫(li)或粗砂(sha)(含水(shui)量要求為(wei)(wei)更(geng)佳含水(shui)量2%左右),人工用(yong)木棒(bang)(bang)在管(guan)(guan)身外向內側進(jin)行夯(hang)(hang)(hang)實,木棒(bang)(bang)的(de)截面尺寸為(wei)(wei)15cm??15cm左右,木棒(bang)(bang)單次沖擊力應達(da)到(dao)9kg,木棒(bang)(bang)作用(yong)點必(bi)需緊貼(tie)管(guan)(guan)身,每個(ge)凹槽部位都必(bi)需夯(hang)(hang)(hang)實到(dao)位,然后用(yong)小型(xing)夯(hang)(hang)(hang)實機械(xie)斜(xie)向夯(hang)(hang)(hang)實,確(que)保(bao)管(guan)(guan)底的(de)回(hui)填質量。
