在鋼波紋涵管施(shi)(shi)(shi)工上要重點控制波紋(wen)管(guan)(guan)(guan)涵楔形部(bu)(bu)及(ji)兩側的(de)回(hui)(hui)填(tian)施(shi)(shi)(shi)工。由于金屬波紋(wen)涵管(guan)(guan)(guan)是一種(zhong)柔性(xing)結構，它建成(cheng)后與附(fu)近回(hui)(hui)填(tian)材料形成(cheng)一種(zhong)組合結構，共(gong)同受力，假如回(hui)(hui)填(tian)不密實或有楔形部(bu)(bu)中空，將(jiang)(jiang)泛起(qi)局部(bu)(bu)有較大變形，存在安全(quan)(quan)(quan)隱患，嚴峻的(de)將(jiang)(jiang)造成(cheng)質量(liang)事故。為確(que)保該涵洞的(de)施(shi)(shi)(shi)工質量(liang)，項目部(bu)(bu)邀請(qing)了(le)技術指導(dao)，組織技術、施(shi)(shi)(shi)工職員(yuan)進行專項培訓學習(xi)，并(bing)要求施(shi)(shi)(shi)工過程(cheng)中技術職員(yuan)施(shi)(shi)(shi)工全(quan)(quan)(quan)過程(cheng)跟蹤指導(dao)功課，做到施(shi)(shi)(shi)工質量(liang)管(guan)(guan)(guan)控到位，有效確(que)保了(le)鋼管(guan)(guan)(guan)波紋(wen)管(guan)(guan)(guan)涵在神佳米(mi)高速公路運營安全(quan)(quan)(quan)。

為何說在鋼波紋涵管施工上要重點控制波紋管涵楔形部？

通過波(bo)(bo)紋(wen)(wen)涵(han)(han)(han)管(guan)在(zai)我項目(mu)部的(de)應用(yong)，總結得出鋼波(bo)(bo)紋(wen)(wen)管(guan)比混凝土(tu)(tu)涵(han)(han)(han)工(gong)效高、周期短，工(gong)藝簡樸、可(ke)操(cao)縱(zong)性(xing)強，工(gong)廠(chang)化加工(gong)、質(zhi)量(liang)輕(qing)易控制。目(mu)前鋼波(bo)(bo)紋(wen)(wen)涵(han)(han)(han)管(guan)一般(ban)合用(yong)于風(feng)積(ji)沙(sha)以(yi)(yi)(yi)及軟土(tu)(tu)地(di)(di)區，它(ta)即可(ke)以(yi)(yi)(yi)解決因地(di)(di)基(ji)(ji)(ji)基(ji)(ji)(ji)礎不(bu)平均沉(chen)降導致的(de)涵(han)(han)(han)洞破(po)壞題目(mu)，又可(ke)以(yi)(yi)(yi)更大程度上分散荷載的(de)效應，更好地(di)(di)施(shi)(shi)展(zhan)鋼結構的(de)上風(feng)。它(ta)不(bu)僅(jin)具有管(guan)壁薄，重量(liang)輕(qing)，便于運輸和存放，施(shi)(shi)工(gong)工(gong)藝簡樸，現(xian)場安裝利便、快速，工(gong)期短等長處，也能(neng)很好地(di)(di)解決地(di)(di)基(ji)(ji)(ji)不(bu)平均沉(chen)降及嚴寒地(di)(di)區天氣對混凝土(tu)(tu)涵(han)(han)(han)結構造成破(po)壞的(de)題目(mu)。按照混凝土(tu)(tu)涵(han)(han)(han)正常施(shi)(shi)工(gong)來(lai)統計，施(shi)(shi)工(gong)時間(jian)為30左右(you)天，可(ke)采用(yong)鋼波(bo)(bo)紋(wen)(wen)涵(han)(han)(han)管(guan)僅(jin)需要8天。同時，不(bu)僅(jin)在(zai)時間(jian)上節約，而且在(zai)本錢上也節約。

焊接鋼筋挨(ai)近波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)時，要(yao)采(cai)用(yong)(yong)方法保護(hu)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)不(bu)得被(bei)燒傷(shang)，如不(bu)到(dao)灼傷(shang)，灼傷(shang)處(chu)要(yao)用(yong)(yong)膠帶(dai)包裹嚴密。考(kao)慮到(dao)頂板波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)數目(mu)逐(zhu)步削(xue)減，但凡與波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)沖突的不(bu)見都要(yao)逃避波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)。澆(jiao)筑(zhu)砼時，制止(zhi)對著(zhu)波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)斜放，拌(ban)和(he)(he)(he)棒(bang)制止(zhi)與波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)觸碰，制止(zhi)兩個拌(ban)和(he)(he)(he)棒(bang)夾(jia)著(zhu)一根波(bo)(bo)紋(wen)(wen)(wen)管(guan)(guan)涵(han)(han)拌(ban)和(he)(he)(he)。特別是(shi)腹(fu)板拌(ban)和(he)(he)(he)時，制止(zhi)拌(ban)和(he)(he)(he)棒(bang)在統一個當(dang)地(di)長(chang)時間拌(ban)和(he)(he)(he)，拌(ban)和(he)(he)(he)時間不(bu)得超越20秒(miao)。

波(bo)紋(wen)(wen)管(guan)(guan)涵(han)接頭(tou)的(de)方(fang)法(fa)：波(bo)紋(wen)(wen)管(guan)(guan)涵(han)接頭(tou)處要(yao)(yao)外包0.3米長得大號(hao)波(bo)紋(wen)(wen)管(guan)(guan)涵(han)，并且兩(liang)端頭(tou)要(yao)(yao)對半擰(ning)緊，基(ji)地不得留有空位。為保證基(ji)地不留空位，應在兩(liang)接頭(tou)端處做好記號(hao)，做好后要(yao)(yao)膠帶包裹嚴密。以防(fang)漏漿。波(bo)紋(wen)(wen)管(guan)(guan)涵(han)方(fang)位定位要(yao)(yao)精準(zhun)，尤(you)其是(shi)挨近接頭(tou)的(de)部(bu)位，波(bo)紋(wen)(wen)管(guan)(guan)涵(han)定位鋼筋距(ju)離(li)為0.5米，不得短少(shao)。

鋼波紋涵管的(de)后(hou)期保護(hu)怎樣處理嚴肅操控進場波紋(wen)(wen)(wen)管涵(han)的(de)原料質量(liang)，進到現(xian)場的(de)波紋(wen)(wen)(wen)管涵(han)要會合堆放規整(zheng)，工人(ren)不得(de)在波紋(wen)(wen)(wen)管涵(han)上轔轢。波紋(wen)(wen)(wen)管涵(han)要掩(yan)蓋(gai)保護(hu)，防止風吹雨淋使其提早老化。切(qie)開波紋(wen)(wen)(wen)管涵(han)要平(ping)直，制止切(qie)成斜口。

波(bo)紋(wen)(wen)管(guan)涵的定義：波(bo)紋(wen)(wen)管(guan)涵是與鋼筋(jin)混凝(ning)土(tu)管(guan)涵比擬，具有管(guan)節薄，重量(liang)輕，便(bian)于運輸存放(fang)，施工工藝(yi)簡(jian)樸，組裝快速，工期短等(deng)長(chang)處(chu)。建筑波(bo)紋(wen)(wen)管(guan)時，可(ke)根據需要隨意組裝成任何長(chang)度(du)，必要時，管(guan)節還可(ke)以拆除，遷(qian)往別(bie)處(chu)修建，在缺乏砂(sha)石材料地(di)(di)區或地(di)(di)基(ji)承載(zai)力(li)較低的地(di)(di)區，波(bo)紋(wen)(wen)管(guan)涵的優勝(sheng)性(xing)更(geng)為明(ming)顯。

波(bo)(bo)紋(wen)(wen)管(guan)涵也(ye)叫金屬波(bo)(bo)紋(wen)(wen)管(guan)涵或鋼制(zhi)波(bo)(bo)紋(wen)(wen)管(guan)涵，是指鋪埋在(zai)公路，鐵(tie)路下(xia)面的涵洞用(yong)(yong)螺紋(wen)(wen)波(bo)(bo)紋(wen)(wen)管(guan)，它是由波(bo)(bo)形(xing)金屬板卷制(zhi)成(cheng)或用(yong)(yong)半圓波(bo)(bo)形(xing)鋼片拼制(zhi)成(cheng)的圓形(xing)波(bo)(bo)紋(wen)(wen)管(guan)，用(yong)(yong)于公路，鐵(tie)路，小橋，通道(dao)，擋土墻(qiang)，以及各種礦場，巷道(dao)擋墻(qiang)支護(hu)等工程的涵洞（管(guan)）。
