澆筑(zhu)砼時，不能對(dui)著(zhu)波(bo)(bo)(bo)(bo)紋(wen)(wen)管放料。振搗棒不能與波(bo)(bo)(bo)(bo)紋(wen)(wen)管碰撞，嚴禁兩個振搗棒夾著(zhu)一根波(bo)(bo)(bo)(bo)紋(wen)(wen)管振搗。特別是腹板振搗時，嚴禁振搗棒在同一位置長(chang)時間(jian)(jian)振搗，振搗時間(jian)(jian)以不超過20秒為準(zhun)。波(bo)(bo)(bo)(bo)紋(wen)(wen)管接頭(tou)的方法：波(bo)(bo)(bo)(bo)紋(wen)(wen)管接頭(tou)處要(yao)外(wai)包0.3米長(chang)的大(da)號波(bo)(bo)(bo)(bo)紋(wen)(wen)管，并且兩端頭(tou)要(yao)對(dui)半擰(ning)緊，中間(jian)(jian)不得留有空(kong)隙。

對比鋼(gang)(gang)筋砼(tong)拱涵(han)(han),鋼(gang)(gang)波紋(wen)(wen)管(guan)(guan)涵(han)(han)具(ju)有以(yi)下優(you)勢:對地基(ji)要(yao)求低,由于鋼(gang)(gang)波紋(wen)(wen)管(guan)(guan)涵(han)(han)為柔性(xing)結構(gou)(gou)物(wu),其基(ji)礎一般也(ye)為柔性(xing)基(ji)礎,涵(han)(han)洞基(ji)底的(de)(de)沉(chen)(chen)降和兩側路基(ji)的(de)(de)沉(chen)(chen)降是均勻的(de)(de),所以(yi)在涵(han)(han)洞構(gou)(gou)筑時不(bu)必單獨對鋼(gang)(gang)波紋(wen)(wen)管(guan)(guan)的(de)(de)基(ji)底進行處理.切割波紋(wen)(wen)管(guan)(guan)要(yao)平直，不(bu)能切成斜口。

搬運(yun)到(dao)現場(chang)的(de)(de)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)要集中堆(dui)放整齊，不能在波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)上踩踏。波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)要覆蓋(gai)保護，防止風吹雨淋使其提前老(lao)化。考慮(lv)到(dao)頂(ding)板波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)數量(liang)在逐(zhu)漸減少，但凡與(yu)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)沖(chong)突的(de)(de)部件(jian)都要避讓(rang)波(bo)紋(wen)管(guan)(guan)(guan)(guan)(guan)。每道(dao)厚約1．5mm,瀝(li)青涂(tu)抹需在回填之(zhi)前進行(xing),該措(cuo)施也可增(zeng)強涵(han)洞(dong)的(de)(de)防水功能,對(dui)腐蝕(shi)及沖(chong)刷較為嚴重的(de)(de)場(chang)合(he),除在外壁(bi)(bi)增(zeng)加2道(dao)熱涂(tu)瀝(li)青層外,可考慮(lv)在管(guan)(guan)(guan)(guan)(guan)內(nei)壁(bi)(bi)包(bao)裹(guo)一層C25細石砼,更能加強涵(han)洞(dong)受水流沖(chong)刷的(de)(de)能力(li).

錨具(ju)用金(jin)屬波(bo)紋(wen)管

焊接(jie)鋼筋靠近波(bo)紋(wen)(wen)(wen)管時，要采取措施(shi)保護波(bo)紋(wen)(wen)(wen)管不(bu)能(neng)被(bei)灼傷(shang)，如果不(bu)小(xiao)心被(bei)灼傷(shang)到，灼傷(shang)處要用膠帶包裹嚴密。波(bo)紋(wen)(wen)(wen)管位(wei)(wei)置定位(wei)(wei)要準確，尤其(qi)(qi)是(shi)靠近接(jie)頭的(de)(de)部位(wei)(wei)，波(bo)紋(wen)(wen)(wen)管定位(wei)(wei)鋼筋間距為0.5米，不(bu)能(neng)缺少。該(gai)文(wen)例舉(ju)的(de)(de)鋼波(bo)紋(wen)(wen)(wen)管涵(han)平均每延米的(de)(de)造價比(bi)同(tong)等規(gui)格的(de)(de)拱(gong)涵(han)低3000元(yuan)左右,而高填方的(de)(de)路段往往涵(han)洞較長,因(yin)此(ci),采用鋼波(bo)紋(wen)(wen)(wen)管涵(han)能(neng)夠(gou)節(jie)約較多造價,若考(kao)慮到鋼波(bo)紋(wen)(wen)(wen)管涵(han)的(de)(de)施(shi)工(gong)便利以及地基處理等方面可(ke)能(neng)節(jie)約的(de)(de)成本,則其(qi)(qi)經濟性更(geng)為可(ke)觀.（hanihanbj.com）
