澆筑砼(tong)時(shi)，制止對著波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)放料。振(zhen)搗(dao)(dao)(dao)(dao)棒(bang)制止與(yu)波(bo)(bo)(bo)紋(wen)管(guan)(guan)碰撞(zhuang)，制止兩個振(zhen)搗(dao)(dao)(dao)(dao)棒(bang)夾(jia)著一根(gen)波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)振(zhen)搗(dao)(dao)(dao)(dao)。特別是腹板振(zhen)搗(dao)(dao)(dao)(dao)時(shi)，制止振(zhen)搗(dao)(dao)(dao)(dao)棒(bang)在同一方(fang)位長(chang)期振(zhen)搗(dao)(dao)(dao)(dao)，振(zhen)搗(dao)(dao)(dao)(dao)時(shi)刻(ke)以不逾越20秒為準。鋼波(bo)(bo)(bo)紋(wen)管(guan)(guan)接頭的(de)方(fang)法：波(bo)(bo)(bo)紋(wen)管(guan)(guan)涵(han)接頭處要外包0.3米長(chang)的(de)大(da)號波(bo)(bo)(bo)紋(wen)管(guan)(guan)。

When pouring concrete, it is forbidden to discharge materials to corrugated pipe culvert. The vibrator shall not collide with the corrugated pipe, and the vibration of two vibrators with one corrugated pipe culvert shall be prevented. Especially when the web is vibrated, the long-term vibration of the vibrator in the same direction shall be prevented, and the vibration time shall not exceed 20 seconds. Method of steel bellows joint: the joint of bellows culvert shall be wrapped with 0.3m long large bellows.

并且兩端(duan)頭(tou)(tou)要對半擰緊(jin)，中心不(bu)(bu)得留(liu)(liu)有空位。為保證中心不(bu)(bu)留(liu)(liu)空位，應在兩接頭(tou)(tou)端(duan)頭(tou)(tou)處做(zuo)(zuo)好符號。做(zuo)(zuo)好后要用膠帶(dai)包裹緊(jin)密，以(yi)防漏漿。從(cong)一側裝置管(guan)節開始，試管(guan)節中心線和根底縱向軸線平行，適當調(diao)節兩管(guan)節相鄰法蘭間距離(li)在2cm左右后，悉數穿上(shang)螺栓(shuan)，擰上(shang)螺絲，帶(dai)平扣即可。

以(yi)此方式逐節依次裝置(zhi)(zhi)銜接，準確放(fang)樣管(guan)(guan)(guan)節軸線位置(zhi)(zhi)，合理安排每節管(guan)(guan)(guan)的位置(zhi)(zhi)。波(bo)紋(wen)管(guan)(guan)(guan)涵管(guan)(guan)(guan)壁(bi)表里(li)涂(tu)刷瀝青(qing)，涂(tu)層(ceng)厚度要到達1mm以(yi)上。用(yong)千斤頂校(xiao)對(dui)整個涵管(guan)(guan)(guan)的軸線，使其(qi)處于(yu)中心(xin)軸線上。鋼波(bo)紋(wen)管(guan)(guan)(guan)，是指鋪埋在公路(lu)、鐵路(lu)路(lu)下的涵洞用(yong)的螺紋(wen)波(bo)紋(wen)管(guan)(guan)(guan)。

它(ta)(ta)是(shi)由波形(xing)(xing)鋼(gang)板(ban)卷制成或用(yong)波形(xing)(xing)鋼(gang)片組(zu)拼成的圓形(xing)(xing)鋼(gang)結構(gou)(gou)管(guan)。它(ta)(ta)的波紋(wen)結構(gou)(gou)可使涵(han)洞路面受力合理，荷(he)載分(fen)布均勻，并具有(you)必定的抗變形(xing)(xing)能(neng)力，能(neng)處理北方冰冷區域（霜凍）對(dui)橋梁和(he)管(guan)涵(han)砼結構(gou)(gou)的損壞問(wen)題。

使路外表沒有伸縮縫，進步行車穩定性；有利于改進軟土地基結構與路堤交界處的“錯臺”現象。當管節悉數銜接結束后，在相鄰法蘭間鑲石棉墊，石棉墊鑲牢后，再以人工對稱鎖緊螺絲，直至外觀調查兩法蘭間隙在2～3mm即可。//hanihanbj.com/
