瀏覽:16919 發布日期:2019-02-21

施工(gong)過程中(zhong),嚴格遵(zun)守操作(zuo)規則,嚴防(fang)落(luo)物傷(shang)人及墜落(luo)事故。各種(zhong)電氣(qi)設備(bei)運轉和漏電保護裝置,不(bu)(bu)準(zhun)隨意改換(huan)安(an)裝方式,尤其對于施工(gong)作(zuo)業的(de)投光燈,裝接工(gong)作(zuo),一(yi)點不(bu)(bu)準(zhun)馬虎、絲毫不(bu)(bu)能漏電,確保安(an)全。所(suo)有容(rong)易碰砸的(de)電氣(qi)設備(bei)加裝防(fang)護罩或遮欄,防(fang)止(zhi)碰傷(shang)危險(xian)。

鋼波紋涵管施工現場(chang)的(de)安(an)全(quan)要求(qiu)有哪些?

波(bo)紋(wen)涵管(guan)管(guan)底兩側模形(xing)部位(wei)的(de)密實度很重(zhong)要,一般設計采(cai)用(yong)現澆C20細(xi)石混凝(ning)土護壁全斷面填(tian)筑,以保證模形(xing)區域的(de)密實,利于波(bo)紋(wen)涵管(guan)的(de)穩定性(xing)。波(bo)紋(wen)涵管(guan)頂部填(tian)土每(mei)層(ceng)厚15cm,壓實度應滿足規(gui)范要求。涵管(guan)沒有達到小填(tian)土高度時,不得使用(yong)大于6T的(de)壓路機械碾(nian)壓,也(ye)不允許(xu)任何(he)重(zhong)型車輛(liang)通行(xing)。

參(can)加金(jin)屬波紋(wen)涵管施工(gong)(gong)(gong)(gong)人員(yuan)要(yao)熟知本工(gong)(gong)(gong)(gong)種的(de)安全(quan)操(cao)作(zuo)(zuo)規程,堅守崗位。特殊(shu)工(gong)(gong)(gong)(gong)種人員(yuan)如電(dian)工(gong)(gong)(gong)(gong)、電(dian)焊工(gong)(gong)(gong)(gong)、混(hun)凝土工(gong)(gong)(gong)(gong)、起(qi)重工(gong)(gong)(gong)(gong)等施工(gong)(gong)(gong)(gong)人員(yuan),必須經過(guo)專門培(pei)訓,熟練(lian)掌握操(cao)作(zuo)(zuo)要(yao)求(qiu),嚴(yan)格執(zhi)行(xing)本工(gong)(gong)(gong)(gong)種的(de)安全(quan)操(cao)作(zuo)(zuo)規程,必須隨身攜帶有關證件(或復印(yin)件)上崗備查(cha)。搭設金(jin)屬波紋(wen)涵管施工(gong)(gong)(gong)(gong)支(zhi)架要(yao)隨時檢查(cha)支(zhi)架的(de)穩定性,并且加固。支(zhi)架完(wan)成后(hou),要(yao)檢查(cha)、驗算支(zhi)架的(de)承(cheng)力,滿足承(cheng)載要(yao)求(qiu)后(hou)再進行(xing)上部施工(gong)(gong)(gong)(gong)。

波紋(wen)涵(han)管頂(ding)部及兩側(ce)(ce)20m范(fan)圍內(nei)不允許使用(yong)機械進行強夯(hang),洞身兩側(ce)(ce)應用(yong)人工或小型(xing)機具對稱夯(hang)填(tian),待填(tian)方高出涵(han)頂(ding)1米(mi)時(shi),可(ke)采用(yong)機械填(tian)筑。在完成回填(tian)之后,終截面尺寸與(yu)組裝時(shi)的尺寸差異更(geng)大(da)不得超(chao)過2%。如截面變(bian)形量(liang)超(chao)過變(bian)形范(fan)圍,應立即終止施工,查(cha)明原因,采取(qu)相應措(cuo)施將變(bian)形量(liang)控制在標準要求(qiu)范(fan)圍內(nei)。

填(tian)筑時應分層填(tian)筑、分層壓(ya)(ya)(ya)實(shi),每層壓(ya)(ya)(ya)實(shi)厚度為15cm,壓(ya)(ya)(ya)實(shi)度要求達(da)到設計要求后方(fang)可進(jin)行(xing)(xing)下一層填(tian)筑。填(tian)筑必須(xu)在波(bo)紋(wen)涵管兩側對(dui)稱同步進(jin)行(xing)(xing),兩側的(de)回(hui)填(tian)土高差不得大于(yu)15cm。對(dui)于(yu)有兩端擋墻的(de)涵洞(dong),回(hui)填(tian)應從兩端向結構中心進(jin)行(xing)(xing)。如果因偏(pian)土壓(ya)(ya)(ya)造成鋼(gang)波(bo)紋(wen)涵管變形的(de),應修正截(jie)面(mian)尺寸(cun)后重新壓(ya)(ya)(ya)實(shi)。

波(bo)紋涵管(guan)(guan)兩(liang)側部位(wei)回填:填土之前,可在(zai)波(bo)紋涵管(guan)(guan)兩(liang)側面用(yong)紅(hong)油漆按每15cm高度作出填高標示,填筑時按標注線控制。在(zai)管(guan)(guan)身更大(da)(da)直徑兩(liang)側50cm外(wai)可采(cai)(cai)用(yong)12~18T的壓路機(ji)應實,50cm范圍(wei)(wei)內采(cai)(cai)用(yong)小型(xing)夯實機(ji)械夯實,以(yi)避免大(da)(da)型(xing)機(ji)械設備對涵管(guan)(guan)的撞擊。靠近管(guan)(guan)體周圍(wei)(wei)50cm范圍(wei)(wei)內,不允許有大(da)(da)于(yu)50mm的石塊、混(hun)凝(ning)土塊或其他(ta)有害腐蝕材料。

壓(ya)(ya)實(shi)(shi)(shi)度要求(qiu):基(ji)(ji)礎應(ying)采用振動壓(ya)(ya)實(shi)(shi)(shi)機(ji)進(jin)行(xing)分層碾壓(ya)(ya),碾壓(ya)(ya)時應(ying)根據回(hui)填(tian)(tian)(tian)材料的含水量及(ji)擊實(shi)(shi)(shi)曲線灑水碾壓(ya)(ya),壓(ya)(ya)實(shi)(shi)(shi)度不(bu)小(xiao)于規(gui)(gui)范(fan)要求(qiu)。具體施工技術要求(qiu)可(ke)參閱《公(gong)路(lu)(lu)路(lu)(lu)基(ji)(ji)設計(ji)規(gui)(gui)范(fan)》和《公(gong)路(lu)(lu)路(lu)(lu)基(ji)(ji)施工技術規(gui)(gui)范(fan)》。波紋涵(han)管兩側及(ji)頂部100cm范(fan)圍(wei)內的回(hui)填(tian)(tian)(tian)及(ji)壓(ya)(ya)實(shi)(shi)(shi)度要求(qiu),圖中涵(han)洞(dong)兩側回(hui)填(tian)(tian)(tian)土壓(ya)(ya)實(shi)(shi)(shi)度要求(qiu)執行(xing),當涵(han)頂填(tian)(tian)(tian)土厚(hou)度超過100cm時,填(tian)(tian)(tian)土壓(ya)(ya)實(shi)(shi)(shi)度與同一標高路(lu)(lu)基(ji)(ji)壓(ya)(ya)實(shi)(shi)(shi)度要求(qiu)相同。(hanihanbj.com
