關于熱天氣下鋼波紋涵管的施工措施有哪些注意事項??

鋼波紋涵管有圓形(xing)(xing)、卵形(xing)(xing)、半圓形(xing)(xing)等,出進口也可根據邊坡比例做成斜口,加工波紋管(guan)(guan)的管(guan)(guan)徑范疇為(wei)Φ0.5m~Φ8m,管(guan)(guan)壁厚度(du)為(wei)3mm~7mm,可以大概饜(yan)足(zu)填土0.5m~40m厚的必要。鋼波紋涵(han)管(guan)(guan)是(shi)接(jie)納波紋狀管(guan)(guan)或(huo)由波紋狀板(ban)(ban)議(yi)決連接(jie)、拼(pin)裝(zhuang)形(xing)(xing)成的一種涵(han)洞情勢。波紋管(guan)(guan)由鋼、鋁或(huo)塑料等質(zhi)料制成。用以替換圓管(guan)(guan)涵(han)、蓋板(ban)(ban)涵(han)、拱(gong)涵(han)和小橋的公(gong)路建(jian)材。對(dui)公(gong)路涵(han)洞來說,涵(han)洞的不勻稱沉降是(shi)其(qi)破(po)壞的緊(jin)張型式之一。

熱(re)天氣鋼波紋涵管施(shi)工(gong)措施(shi):1、熱(re)期混(hun)(hun)(hun)(hun)凝(ning)土(tu)施(shi)工(gong)時,應(ying)(ying)(ying)對(dui)拌(ban)和(he)用水(shui)(shui)采取降溫(wen)處理措施(shi),以控制混(hun)(hun)(hun)(hun)凝(ning)土(tu)灌注(zhu)溫(wen)度在30℃以下,并應(ying)(ying)(ying)考慮高溫(wen)對(dui)混(hun)(hun)(hun)(hun)凝(ning)土(tu)塌(ta)落度損失(shi)的影響(xiang)。混(hun)(hun)(hun)(hun)凝(ning)土(tu)不得(de)在運輸(shu)過(guo)程中(zhong)加水(shui)(shui)攪拌(ban)。 2、如條件具備(bei),應(ying)(ying)(ying)遮蓋防曬,降低模(mo)(mo)板(ban)(ban)(ban)和(he)鋼筋溫(wen)度;亦可在模(mo)(mo)板(ban)(ban)(ban)和(he)鋼筋上灑水(shui)(shui)降溫(wen),但在澆筑混(hun)(hun)(hun)(hun)凝(ning)土(tu)時模(mo)(mo)板(ban)(ban)(ban)內不能有(you)積水(shui)(shui)或附著水(shui)(shui)。混(hun)(hun)(hun)(hun)凝(ning)土(tu)運輸(shu)車應(ying)(ying)(ying)有(you)攪拌(ban)裝置(zhi),且(qie)罐(guan)體應(ying)(ying)(ying)有(you)防曬措施(shi)。混(hun)(hun)(hun)(hun)凝(ning)土(tu)在運輸(shu)過(guo)程中(zhong)應(ying)(ying)(ying)慢(man)速不間斷地(di)攪拌(ban),并大限度縮短運輸(shu)時間。模(mo)(mo)板(ban)(ban)(ban)應(ying)(ying)(ying)在內溫(wen)度較(jiao)低時候拆除,拆模(mo)(mo)后混(hun)(hun)(hun)(hun)凝(ning)土(tu)表面應(ying)(ying)(ying)保(bao)濕(shi)養(yang)護不少于(yu)7天。

施(shi)(shi)工(gong)(gong)(gong)過程中,嚴格遵(zun)守操(cao)(cao)作(zuo)規則,嚴防落(luo)物傷(shang)人及墜落(luo)事故。各(ge)種(zhong)電氣設備運轉和漏電保護(hu)裝置,不準隨意改換安(an)裝方(fang)式,尤其對于施(shi)(shi)工(gong)(gong)(gong)作(zuo)業的(de)(de)投光燈(deng),裝接工(gong)(gong)(gong)作(zuo),一點(dian)不準馬虎、絲(si)毫不能漏電,確保安(an) 全(quan)。所有(you)(you)容易(yi)碰砸的(de)(de)電氣設備加(jia)裝防護(hu)罩或遮欄,防止碰傷(shang)危(wei)險。五、參加(jia)金(jin)屬波紋涵(han)管施(shi)(shi)工(gong)(gong)(gong)人員要(yao)熟知本工(gong)(gong)(gong)種(zhong)的(de)(de)安(an) 全(quan)操(cao)(cao)作(zuo)規程,堅守崗(gang)(gang)位。特殊工(gong)(gong)(gong)種(zhong)人員如電工(gong)(gong)(gong)、電焊工(gong)(gong)(gong)、混凝土工(gong)(gong)(gong)、起(qi)重工(gong)(gong)(gong)等(deng)施(shi)(shi)工(gong)(gong)(gong)人員,必(bi) 須(xu)經過專門培(pei)訓,熟練(lian)(lian)掌(zhang)握操(cao)(cao)作(zuo)要(yao)求,嚴格執行(xing)本工(gong)(gong)(gong)種(zhong)的(de)(de)安(an) 全(quan)操(cao)(cao)作(zuo)規程,必(bi) 須(xu)隨身(shen)攜帶有(you)(you)關證件(jian)(或復印(yin)件(jian))上崗(gang)(gang)備查。搭設金(jin)屬波紋涵(han)管施(shi)(shi)工(gong)(gong)(gong)支(zhi)架要(yao)隨時檢(jian)查支(zhi)架的(de)(de)穩(wen)定性,并且加(jia)固。支(zhi)架完(wan)成(cheng)后,要(yao)檢(jian)查、驗(yan)算(suan)支(zhi)架的(de)(de)承(cheng)力,滿足承(cheng)載要(yao)求后再進行(xing)上部施(shi)(shi)工(gong)(gong)(gong)。起(qi)吊作(zuo)業須(xu)有(you)(you)專職安(an) 全(quan)人員現(xian)場監控,操(cao)(cao)作(zuo)手必(bi) 須(xu)是(shi)熟練(lian)(lian)工(gong)(gong)(gong),且經過安(an) 全(quan)培(pei)訓,現(xian)場配有(you)(you)管理人員統一調(diao)配指揮。
