施工過程中,嚴格遵守(shou)操作(zuo)規則,嚴防落(luo)物(wu)傷(shang)人(ren)及(ji)墜落(luo)事故。各種電(dian)(dian)(dian)氣設(she)備(bei)運轉(zhuan)和漏電(dian)(dian)(dian)保(bao)護(hu)裝(zhuang)置,不(bu)準(zhun)隨意改換安(an)裝(zhuang)方式(shi),尤(you)其對于施工作(zuo)業的(de)投(tou)光燈,裝(zhuang)接工作(zuo),一點不(bu)準(zhun)馬虎、絲毫不(bu)能(neng)漏電(dian)(dian)(dian),確保(bao)安(an)全。所有容(rong)易碰(peng)砸(za)的(de)電(dian)(dian)(dian)氣設(she)備(bei)加(jia)裝(zhuang)防護(hu)罩或遮(zhe)欄,防止碰(peng)傷(shang)危(wei)險(xian)。

鋼波紋涵管施工現場的(de)安(an)全(quan)要求有哪些?

波紋(wen)(wen)涵(han)(han)管(guan)(guan)管(guan)(guan)底兩側模形部位的(de)密實(shi)(shi)度(du)很重要(yao),一般(ban)設計采用現澆(jiao)C20細石混(hun)凝土(tu)護壁全斷(duan)面填筑,以保證(zheng)模形區(qu)域的(de)密實(shi)(shi),利于波紋(wen)(wen)涵(han)(han)管(guan)(guan)的(de)穩定性。波紋(wen)(wen)涵(han)(han)管(guan)(guan)頂(ding)部填土(tu)每(mei)層厚15cm,壓實(shi)(shi)度(du)應滿足規范要(yao)求。涵(han)(han)管(guan)(guan)沒(mei)有達到(dao)小填土(tu)高度(du)時,不得使用大于6T的(de)壓路機(ji)械碾壓,也不允(yun)許任(ren)何(he)重型(xing)車輛通行。

參加金(jin)屬波紋涵管施(shi)(shi)工(gong)(gong)(gong)(gong)人員(yuan)要(yao)熟(shu)知本工(gong)(gong)(gong)(gong)種(zhong)的安全操(cao)作規程(cheng),堅守崗位。特殊工(gong)(gong)(gong)(gong)種(zhong)人員(yuan)如(ru)電工(gong)(gong)(gong)(gong)、電焊工(gong)(gong)(gong)(gong)、混凝(ning)土工(gong)(gong)(gong)(gong)、起重工(gong)(gong)(gong)(gong)等施(shi)(shi)工(gong)(gong)(gong)(gong)人員(yuan),必須經過專(zhuan)門培訓,熟(shu)練掌握操(cao)作要(yao)求(qiu),嚴格執(zhi)行(xing)本工(gong)(gong)(gong)(gong)種(zhong)的安全操(cao)作規程(cheng),必須隨身攜帶有關證件(或復印件)上(shang)崗備查(cha)。搭設金(jin)屬波紋涵管施(shi)(shi)工(gong)(gong)(gong)(gong)支(zhi)架(jia)要(yao)隨時檢查(cha)支(zhi)架(jia)的穩定性(xing),并且加固。支(zhi)架(jia)完成后(hou),要(yao)檢查(cha)、驗算支(zhi)架(jia)的承(cheng)(cheng)力,滿足承(cheng)(cheng)載要(yao)求(qiu)后(hou)再(zai)進行(xing)上(shang)部施(shi)(shi)工(gong)(gong)(gong)(gong)。

波紋(wen)涵管頂部(bu)及兩側(ce)20m范(fan)圍(wei)(wei)內不允許使用機(ji)械進行強夯,洞身(shen)兩側(ce)應用人工或小型(xing)機(ji)具對稱夯填,待填方高出(chu)涵頂1米時,可采用機(ji)械填筑。在完成回填之(zhi)后,終(zhong)截面尺寸與組裝時的(de)尺寸差異更大不得(de)超(chao)過(guo)2%。如截面變形量超(chao)過(guo)變形范(fan)圍(wei)(wei),應立即終(zhong)止施工,查明原因,采取相應措施將變形量控制在標(biao)準要(yao)求范(fan)圍(wei)(wei)內。

填筑(zhu)時應(ying)分層(ceng)填筑(zhu)、分層(ceng)壓實(shi),每層(ceng)壓實(shi)厚度為15cm,壓實(shi)度要求達到(dao)設計要求后方可(ke)進行(xing)下一層(ceng)填筑(zhu)。填筑(zhu)必須(xu)在波(bo)紋涵(han)管兩(liang)側對(dui)稱同(tong)步進行(xing),兩(liang)側的回填土高差不得大于15cm。對(dui)于有(you)兩(liang)端擋墻的涵(han)洞,回填應(ying)從(cong)兩(liang)端向結構(gou)中心進行(xing)。如果因(yin)偏土壓造成鋼波(bo)紋涵(han)管變形的,應(ying)修(xiu)正截面尺寸后重(zhong)新壓實(shi)。

波紋涵管兩(liang)側(ce)部位回(hui)填(tian):填(tian)土之前,可在(zai)波紋涵管兩(liang)側(ce)面用紅油漆按每15cm高(gao)度作(zuo)出填(tian)高(gao)標示(shi),填(tian)筑時(shi)按標注線控制。在(zai)管身更(geng)大直徑兩(liang)側(ce)50cm外可采(cai)用12~18T的(de)(de)壓路(lu)機應實(shi),50cm范圍內(nei)采(cai)用小型夯實(shi)機械(xie)(xie)夯實(shi),以避免大型機械(xie)(xie)設備對(dui)涵管的(de)(de)撞擊。靠近管體周圍50cm范圍內(nei),不允許有大于50mm的(de)(de)石塊、混凝土塊或(huo)其他有害(hai)腐(fu)蝕材(cai)料(liao)。

壓(ya)(ya)(ya)實(shi)度(du)(du)要求(qiu)(qiu):基(ji)礎應采用振動壓(ya)(ya)(ya)實(shi)機進行分層碾壓(ya)(ya)(ya),碾壓(ya)(ya)(ya)時應根據回填(tian)材料的含水(shui)量及擊實(shi)曲線灑水(shui)碾壓(ya)(ya)(ya),壓(ya)(ya)(ya)實(shi)度(du)(du)不小于規(gui)范(fan)要求(qiu)(qiu)。具體施(shi)工技(ji)術(shu)要求(qiu)(qiu)可參(can)閱《公(gong)路路基(ji)設計規(gui)范(fan)》和《公(gong)路路基(ji)施(shi)工技(ji)術(shu)規(gui)范(fan)》。波(bo)紋涵管(guan)兩側(ce)及頂(ding)部100cm范(fan)圍(wei)內的回填(tian)及壓(ya)(ya)(ya)實(shi)度(du)(du)要求(qiu)(qiu),圖中涵洞兩側(ce)回填(tian)土(tu)壓(ya)(ya)(ya)實(shi)度(du)(du)要求(qiu)(qiu)執(zhi)行,當涵頂(ding)填(tian)土(tu)厚度(du)(du)超過(guo)100cm時,填(tian)土(tu)壓(ya)(ya)(ya)實(shi)度(du)(du)與同一標高路基(ji)壓(ya)(ya)(ya)實(shi)度(du)(du)要求(qiu)(qiu)相(xiang)同。(hanihanbj.com
