鋼波(bo)紋涵管(guan)施工現(xian)場的安全要求有哪(na)些？
波(bo)紋涵(han)管管底兩側模形(xing)部位的(de)密實(shi)度(du)很重要，一(yi)般(ban)設計采(cai)用現澆(jiao)C20細石(shi)混(hun)凝(ning)土(tu)護壁全斷面填(tian)筑，以(yi)保(bao)證模形(xing)區域的(de)密實(shi)，利于波(bo)紋涵(han)管的(de)穩定性。波(bo)紋涵(han)管頂部填(tian)土(tu)每層厚(hou)15cm，壓(ya)實(shi)度(du)應滿足(zu)規范要求。涵(han)管沒有達到(dao)小(xiao)填(tian)土(tu)高度(du)時，不(bu)(bu)得(de)使用大(da)于6T的(de)壓(ya)路機(ji)械碾壓(ya)，也不(bu)(bu)允許任何重型車輛通行(xing)。

參加金屬波紋涵管施(shi)工(gong)(gong)(gong)人(ren)員(yuan)要(yao)熟(shu)(shu)知本工(gong)(gong)(gong)種的安全操作(zuo)規程(cheng)，堅守崗(gang)位。特殊工(gong)(gong)(gong)種人(ren)員(yuan)如電(dian)工(gong)(gong)(gong)、電(dian)焊(han)工(gong)(gong)(gong)、混凝土工(gong)(gong)(gong)、起重工(gong)(gong)(gong)等施(shi)工(gong)(gong)(gong)人(ren)員(yuan)，必須經過專門培訓，熟(shu)(shu)練掌握(wo)操作(zuo)要(yao)求，嚴格執行(xing)本工(gong)(gong)(gong)種的安全操作(zuo)規程(cheng)，必須隨身(shen)攜帶有關證(zheng)件(jian)（或復印件(jian)）上(shang)崗(gang)備查。搭設金屬波紋涵管施(shi)工(gong)(gong)(gong)支架(jia)(jia)要(yao)隨時檢查支架(jia)(jia)的穩定性，并且加固。支架(jia)(jia)完成(cheng)后，要(yao)檢查、驗算(suan)支架(jia)(jia)的承(cheng)力，滿足承(cheng)載要(yao)求后再(zai)進行(xing)上(shang)部施(shi)工(gong)(gong)(gong)。
波紋涵管(guan)頂(ding)部及兩側20m范圍(wei)(wei)內(nei)不(bu)允許使用機(ji)械進(jin)行強夯，洞身兩側應(ying)用人工(gong)或(huo)小型機(ji)具對稱夯填，待填方高(gao)出涵頂(ding)1米時(shi)，可采(cai)用機(ji)械填筑。在(zai)完(wan)成回(hui)填之后(hou)，終截面尺寸與組裝時(shi)的尺寸差異更大不(bu)得超過2%。如截面變形量超過變形范圍(wei)(wei)，應(ying)立即終止施工(gong)，查明原因，采(cai)取相應(ying)措施將變形量控制在(zai)標準要求范圍(wei)(wei)內(nei)。
填筑(zhu)時(shi)應分層(ceng)填筑(zhu)、分層(ceng)壓(ya)實，每(mei)層(ceng)壓(ya)實厚度為15cm，壓(ya)實度要求(qiu)達到(dao)設計要求(qiu)后(hou)方可進行(xing)下一層(ceng)填筑(zhu)。填筑(zhu)必須在波(bo)紋(wen)(wen)涵管兩側對(dui)稱同(tong)步進行(xing)，兩側的(de)回填土高差不得大于(yu)(yu)15cm。對(dui)于(yu)(yu)有兩端(duan)擋墻(qiang)的(de)涵洞，回填應從兩端(duan)向結構中心進行(xing)。如(ru)果因偏土壓(ya)造(zao)成鋼波(bo)紋(wen)(wen)涵管變(bian)形的(de)，應修正截(jie)面尺寸(cun)后(hou)重(zhong)新壓(ya)實。
波(bo)紋(wen)涵管(guan)(guan)兩(liang)側部位回填：填土之(zhi)前(qian)，可(ke)在波(bo)紋(wen)涵管(guan)(guan)兩(liang)側面用紅(hong)油漆按每(mei)15cm高度作出填高標示，填筑時(shi)按標注線控制。在管(guan)(guan)身更大直(zhi)徑兩(liang)側50cm外可(ke)采(cai)用12～18T的壓(ya)路機應實(shi)，50cm范圍內采(cai)用小(xiao)型(xing)夯實(shi)機械(xie)夯實(shi)，以(yi)避免大型(xing)機械(xie)設備(bei)對涵管(guan)(guan)的撞擊(ji)。靠近(jin)管(guan)(guan)體周圍50cm范圍內，不允許有大于(yu)50mm的石塊、混(hun)凝土塊或其他有害腐蝕材料。
