各種(zhong)電(dian)氣(qi)設備運(yun)轉(zhuan)和漏電(dian)保護(hu)裝(zhuang)置(zhi),不準隨意改(gai)換安裝(zhuang)方式,尤其對于施工(gong)作業的投光燈(deng),裝(zhuang)接工(gong)作,一點不準馬(ma)虎、絲(si)毫(hao)不能漏電(dian),確保安全。所有(you)容易(yi)碰砸的電(dian)氣(qi)設備加裝(zhuang)防護(hu)罩或遮欄,防止碰傷危險(xian)。鋼波紋涵管頂部填土每層厚15cm,壓(ya)實度應(ying)滿足規(gui)范(fan)要求(qiu)。

鋼(gang)波紋涵管在填筑過程(cheng)中不能(neng)絲毫馬(ma)虎(hu)

靠(kao)近管(guan)體周圍50cm范圍內(nei),不(bu)允許有大于50mm的石塊、混凝(ning)土(tu)塊或其他有害腐蝕(shi)材料(liao)。填筑時應分(fen)層(ceng)填筑、分(fen)層(ceng)壓(ya)(ya)實,每(mei)層(ceng)壓(ya)(ya)實厚(hou)度為15cm,壓(ya)(ya)實度要(yao)求達到設計要(yao)求后方可進行下(xia)一(yi)層(ceng)填筑。填筑必(bi)須在波(bo)紋涵(han)管(guan)兩(liang)(liang)側對稱同步進行,兩(liang)(liang)側的回填土(tu)高(gao)差不(bu)得大于15cm。

對于有兩端擋墻的(de)涵(han)洞,回填(tian)應從兩端向結(jie)構中(zhong)心(xin)進(jin)行(xing)。如果因偏土(tu)壓(ya)(ya)造成(cheng)鋼波紋涵(han)管(guan)變形的(de),應修正截面尺寸后(hou)重(zhong)新(xin)壓(ya)(ya)實(shi)(shi)。波紋涵(han)管(guan)兩側及頂部100cm范圍內的(de)回填(tian)及壓(ya)(ya)實(shi)(shi)度(du)(du)要求,應按照設(she)計(ji)文件(jian)《橋(qiao)頭(tou)路基(ji)(ji)處理設(she)計(ji)圖(三)》圖中(zhong)涵(han)洞兩側回填(tian)土(tu)壓(ya)(ya)實(shi)(shi)度(du)(du)要求執(zhi)行(xing),當涵(han)頂填(tian)土(tu)厚(hou)度(du)(du)超過100cm時,填(tian)土(tu)壓(ya)(ya)實(shi)(shi)度(du)(du)與同一標高路基(ji)(ji)壓(ya)(ya)實(shi)(shi)度(du)(du)要求相同。

如截面變(bian)(bian)形量(liang)超過變(bian)(bian)形范圍(wei),應立即(ji)終止施(shi)(shi)工,查(cha)明原因,采(cai)取相應措施(shi)(shi)將(jiang)變(bian)(bian)形量(liang)控制在標準要求范圍(wei)內。波(bo)紋(wen)涵管兩側及頂(ding)部的部位(wei)回填按照設(she)計文件要求采(cai)用礫類土(tu)回填,管頂(ding)填土(tu)應在管兩側保持對稱均勻、分層(ceng)攤鋪(pu)、逐(zhu)層(ceng)壓實。開工前(qian)各種機(ji)具設(she)備必須(xu)進(jin)行(xing)檢修(xiu)、試運(yun)行(xing),使(shi)之處于完(wan)好、正(zheng)常運(yun)轉狀(zhuang)態(tai),并定期檢修(xiu)保養。電器必須(xu)由(you)專職電工安裝和修(xiu)理,設(she)置(zhi)標志,嚴禁(jin)酒后施(shi)(shi)工。

施工(gong)過程中(zhong),嚴格遵守操作規則,嚴防落(luo)物傷人及墜(zhui)落(luo)事故。波紋(wen)涵管頂(ding)部及兩(liang)側20m范(fan)圍內不允許(xu)使用(yong)機械進行強夯,洞(dong)身兩(liang)側應(ying)用(yong)人工(gong)或小型機具(ju)對稱夯填(tian),待填(tian)方高(gao)出涵頂(ding)1米時,可采用(yong)機械填(tian)筑(zhu)。在完成(cheng)回填(tian)之后(hou),終截面尺寸與組裝時的尺寸差異更大不得超過2%。

具(ju)體施(shi)工技(ji)術要(yao)(yao)求(qiu)可(ke)參閱《公路(lu)(lu)路(lu)(lu)基(ji)設計規范》和《公路(lu)(lu)路(lu)(lu)基(ji)施(shi)工技(ji)術規范》。搭設金(jin)屬(shu)波紋涵管施(shi)工支架(jia)要(yao)(yao)隨時檢(jian)查支架(jia)的穩定性,并且(qie)加固(gu)。支架(jia)完成后,要(yao)(yao)檢(jian)查、驗算支架(jia)的承力,滿足承載要(yao)(yao)求(qiu)后再進行(xing)上(shang)部施(shi)工。

波紋涵管管底兩側模(mo)形(xing)部位的(de)密(mi)(mi)實(shi)度(du)很重要,一般設計采(cai)用(yong)現澆C20細石混凝土護壁全斷(duan)面填(tian)筑,以保證模(mo)形(xing)區域的(de)密(mi)(mi)實(shi),利于(yu)波紋涵管的(de)穩(wen)定(ding)性(xing)。壓(ya)(ya)(ya)(ya)實(shi)度(du)要求:基礎(chu)應采(cai)用(yong)振(zhen)動壓(ya)(ya)(ya)(ya)實(shi)機進(jin)行分層碾壓(ya)(ya)(ya)(ya),碾壓(ya)(ya)(ya)(ya)時應根據回填(tian)材料的(de)含水量及擊實(shi)曲(qu)線灑水碾壓(ya)(ya)(ya)(ya),壓(ya)(ya)(ya)(ya)實(shi)度(du)不小于(yu)規范要求。

涵(han)管沒有(you)達到小(xiao)填土(tu)高度時,不得(de)使(shi)用大(da)于6T的壓(ya)(ya)路機械碾壓(ya)(ya),也不允許任(ren)何重型車輛通行(xing)。參加金(jin)屬(shu)波紋涵(han)管施工(gong)(gong)(gong)人(ren)員(yuan)要熟知本工(gong)(gong)(gong)種(zhong)(zhong)的安(an)全操(cao)作(zuo)規(gui)(gui)程,堅守崗位。特殊工(gong)(gong)(gong)種(zhong)(zhong)人(ren)員(yuan)如電工(gong)(gong)(gong)、電焊工(gong)(gong)(gong)、混(hun)凝土(tu)工(gong)(gong)(gong)、起重工(gong)(gong)(gong)等(deng)施工(gong)(gong)(gong)人(ren)員(yuan),必須(xu)經(jing)過專門培訓,熟練掌(zhang)握操(cao)作(zuo)要求,嚴格執行(xing)本工(gong)(gong)(gong)種(zhong)(zhong)的安(an)全操(cao)作(zuo)規(gui)(gui)程,必須(xu)隨身攜帶有(you)關證件(或復(fu)印件)上崗備(bei)查。

波紋涵(han)管兩側(ce)部(bu)位回(hui)填(tian):填(tian)土(tu)之(zhi)前(qian),可在(zai)波紋涵(han)管兩側(ce)面用紅油漆按每15cm高(gao)度作出填(tian)高(gao)標(biao)示,填(tian)筑時按標(biao)注線控(kong)制。在(zai)管身(shen)更(geng)大直徑兩側(ce)50cm外可采用12~18T的壓(ya)路機應實,50cm范圍(wei)內采用小型夯實機械夯實,以避免大型機械設備對涵(han)管的撞擊。(hanihanbj.com
