在管(guan)身更大直徑兩側50cm外(wai)可采用(yong)12~18T的壓路機(ji)應(ying)實,50cm范圍(wei)內(nei)采用(yong)小型夯實機(ji)械(xie)夯實,以避免大型機(ji)械(xie)設備對涵管(guan)的撞(zhuang)擊。靠近管(guan)體周圍(wei)50cm范圍(wei)內(nei),不(bu)允許有大于(yu)50mm的石塊(kuai)、混凝土(tu)塊(kuai)或其(qi)他有害腐蝕材料(liao)。
開工(gong)前(qian)各種(zhong)機具(ju)設(she)備必須進(jin)行(xing)(xing)檢(jian)修(xiu)(xiu)、試運行(xing)(xing),使(shi)之處于完好、正(zheng)常運轉(zhuan)狀態,并定期檢(jian)修(xiu)(xiu)保養。電(dian)器必須由專職電(dian)工(gong)安裝和修(xiu)(xiu)理,設(she)置(zhi)標(biao)志,嚴(yan)禁酒后施工(gong)。鋼波紋涵管在出廠前(qian)應嚴(yan)格按(an)鋼質波紋板加工(gong)驗收(shou)標(biao)準進(jin)行(xing)(xing)驗收(shou),并進(jin)行(xing)(xing)必要(yao)的預拼裝。
如果因偏土(tu)壓造成(cheng)鋼(gang)波紋涵管變形的,應修正(zheng)截面尺(chi)寸后重新壓實。波紋鋼(gang)板安(an)裝鋪(pu)設應平順、穩固(gu)、管底坡(po)度不得出現反坡(po),管涵內不得有泥土(tu)、磚石等雜(za)物(wu)。基礎的地基承載力(li)必(bi)須(xu)滿(man)足沒計要求(qiu),嚴(yan)禁超(chao)挖回填虛土(tu)超(chao)過以及標高(gao)控制。
填(tian)筑(zhu)時應分層(ceng)填(tian)筑(zhu)、分層(ceng)壓(ya)實,每層(ceng)壓(ya)實厚度(du)為15cm,壓(ya)實度(du)要求達到設計要求后(hou)方(fang)可進(jin)行(xing)下一層(ceng)填(tian)筑(zhu)。填(tian)筑(zhu)必(bi)須在(zai)波紋涵管(guan)兩(liang)側對稱同步(bu)進(jin)行(xing),兩(liang)側的回(hui)填(tian)土高差不得大于15cm。對于有兩(liang)端(duan)擋墻的涵洞,回(hui)填(tian)應從兩(liang)端(duan)向(xiang)結(jie)構中心(xin)進(jin)行(xing)。
參(can)加金屬波(bo)紋涵管施工(gong)(gong)(gong)(gong)人員要熟(shu)知本工(gong)(gong)(gong)(gong)種(zhong)的安全(quan)操作(zuo)規(gui)程,堅守崗位。特殊工(gong)(gong)(gong)(gong)種(zhong)人員如(ru)電工(gong)(gong)(gong)(gong)、電焊工(gong)(gong)(gong)(gong)、混凝土(tu)工(gong)(gong)(gong)(gong)、起(qi)重工(gong)(gong)(gong)(gong)等施工(gong)(gong)(gong)(gong)人員,必(bi)須(xu)經過專門(men)培訓,熟(shu)練掌握操作(zuo)要求,嚴格執(zhi)行本工(gong)(gong)(gong)(gong)種(zhong)的安全(quan)操作(zuo)規(gui)程,必(bi)須(xu)隨身(shen)攜帶有關(guan)證(zheng)件(或(huo)復印件)上崗備查(cha)。
公路鋼波紋管
鋼波(bo)紋涵管(guan)接(jie)縫(feng)處(chu)必(bi)(bi)須結合(he)緊密,防水密封材(cai)料有效。鋼波(bo)紋涵管(guan)在(zai)安裝時(shi),拼(pin)接(jie)處(chu)必(bi)(bi)須清理(li)干凈(jing)。以確保(bao)拼(pin)縫(feng)搭接(jie)緊密。波(bo)紋涵管(guan)兩(liang)側(ce)部位回填(tian):填(tian)土之前,可在(zai)波(bo)紋涵管(guan)兩(liang)側(ce)面用(yong)紅油漆按每(mei)15cm高(gao)度(du)作出填(tian)高(gao)標示,填(tian)筑時(shi)按標注(zhu)線(xian)控制。
鋼波(bo)(bo)紋(wen)涵(han)管(guan)單體出廠(chang)時,必(bi)須附有(you)(you)產品(pin)質量合格(ge)(ge)證書,沒有(you)(you)合格(ge)(ge)證書的(de)一律(lv)不能出廠(chang)。基本要求:鋼波(bo)(bo)紋(wen)涵(han)管(guan)運(yun)到施工(gong)現場后,必(bi)須逐塊檢查,凡在(zai)運(yun)輸(shu)過程中變形的(de)鋼板(ban)不得使用。各(ge)種電(dian)氣設備運(yun)轉和漏(lou)電(dian)保(bao)護裝置,不準(zhun)隨意(yi)改換安裝方式,尤其對于施工(gong)作(zuo)業(ye)的(de)投光燈,裝接工(gong)作(zuo),一點不準(zhun)馬虎、絲(si)毫不能漏(lou)電(dian),確保(bao)安全。(hanihanbj.com)
