防(fang)護棚的拆(chai)除操(cao)作規(gui)程(cheng)

在(zai)靠近架空輸電(dian)(dian)(dian)線(xian)路拆(chai)除(chu)(chu)防(fang)護(hu)棚時(shi)，安(an)全防(fang)護(hu)棚，必須(xu)按供電(dian)(dian)(dian)局(ju)規(gui)(gui)定確保一(yi)定的安(an)全距離，必要時(shi)切斷(duan)電(dian)(dian)(dian)源或(huo)遷(qian)移電(dian)(dian)(dian)線(xian)。拆(chai)除(chu)(chu)作(zuo)業(ye)(ye)過程中必須(xu)使用電(dian)(dian)(dian)焊氣割(ge)工(gong)藝(yi)時(shi)，應嚴格按照國家特殊工(gong)種的要求和消防(fang)規(gui)(gui)定執行，安(an)全防(fang)護(hu)棚現(xian)(xian)貨，嚴格遵守(shou)焊割(ge)作(zuo)業(ye)(ye)安(an)全操作(zuo)規(gui)(gui)程。作(zuo)業(ye)(ye)前(qian)，清除(chu)(chu)施(shi)(shi)工(gong)現(xian)(xian)場(chang)所有易1燃易1爆(bao)物品。施(shi)(shi)工(gong)現(xian)(xian)場(chang)必須(xu)配(pei)備滅火(huo)(huo)器等消防(fang)器材(cai)，必須(xu)有防(fang)火(huo)(huo)措施(shi)(shi)和專人看守(shou)；配(pei)備料(liao)斗（桶），防(fang)止火(huo)(huo)星(xing)和切割(ge)物濺落(luo)。嚴禁無證(zheng)人員從(cong)事(shi)焊割(ge)作(zuo)業(ye)(ye)。

 街面人行通(tong)(tong)(tong)道距離施(shi)工建(jian)(jian)(jian)筑(zhu)達不(bu)(bu)(bu)到安(an)全(quan)距離時，必(bi)須(xu)搭設用于行人通(tong)(tong)(tong)行的(de)防(fang)護通(tong)(tong)(tong)道，其凈空 高(gao)度(du)(du)不(bu)(bu)(bu)低于 3 m，搭設方式與施(shi)工現場(chang)安(an)全(quan)通(tong)(tong)(tong)道相同，并設置明(ming)確的(de)警示(shi)標(biao)(biao)牌、引(yin)導標(biao)(biao)志和(he)設施(shi)。例如配電箱、鋼筋、電梯、木(mu)工、攪拌機等均(jun)需要在其周圍設置防(fang)護棚，而 防(fang)護棚的(de)質量會(hui)對后期使用的(de)安(an)全(quan)產生影響。安(an)全(quan)通(tong)(tong)(tong)道凈空高(gao)度(du)(du)和(he)寬度(du)(du)應根據通(tong)(tong)(tong)道所處位置及人、車通(tong)(tong)(tong)行要求(qiu)確定，高(gao)度(du)(du)一般(ban)不(bu)(bu)(bu)低于3.5 m，寬度(du)(du)一般(ban)不(bu)(bu)(bu)低于 3m。高(gao)度(du)(du)在 15 m 以下建(jian)(jian)(jian)筑(zhu)物，其進出口(kou)(kou)通(tong)(tong)(tong)道長(chang)度(du)(du)不(bu)(bu)(bu)低于 3 m；高(gao)度(du)(du)在 15-30m 的(de)建(jian)(jian)(jian)筑(zhu)物，其進出口(kou)(kou)通(tong)(tong)(tong)道長(chang)度(du)(du)不(bu)(bu)(bu)低于 4 m，安(an)全(quan)防(fang)護棚生產，高(gao)度(du)(du)超(chao)過 30 m 的(de)建(jian)(jian)(jian)筑(zhu)物，其進出口(kou)(kou)通(tong)(tong)(tong)道長(chang)度(du)(du)不(bu)(bu)(bu)低于 5 m。通(tong)(tong)(tong)道長(chang)度(du)(du)自(zi)腳手架(jia)外排立桿起算。

 當臨街通(tong)道(dao)、場內通(tong)道(dao)、出入建筑物(wu)(wu)通(tong)道(dao)、施工(gong)電梯及(ji)(ji)物(wu)(wu)料(liao)提升機地(di)面進料(liao)口作(zuo)業通(tong)道(dao)處 于墜落半徑(jing)內或處于起(qi)重(zhong)機起(qi)重(zhong)臂回轉范圍(wei)內時，必須設(she)置防(fang)護(hu)(hu)(hu)(hu)棚(peng)及(ji)(ji)防(fang)護(hu)(hu)(hu)(hu)通(tong)道(dao)，以避免發生物(wu)(wu)體打 擊事故。 在(zai)安(an)(an)全(quan)(quan)(quan)(quan)防(fang)護(hu)(hu)(hu)(hu)棚(peng)搭設(she)過程中，剪(jian)刀撐應(ying)隨架(jia)體搭設(she)高度同步進行。由于安(an)(an)全(quan)(quan)(quan)(quan)防(fang)護(hu)(hu)(hu)(hu)棚(peng)的施工(gong)質量會對后(hou)期使用(yong)的安(an)(an)全(quan)(quan)(quan)(quan)產生較大影(ying)響，因此，在(zai)搭設(she)安(an)(an)全(quan)(quan)(quan)(quan)防(fang)護(hu)(hu)(hu)(hu)棚(peng)的過程中應(ying)注意(yi)一點。防(fang)護(hu)(hu)(hu)(hu)棚(peng)在(zai)搭設(she)完成后(hou)，施工(gong)單(dan)位應(ying)先(xian)組(zu)織安(an)(an)全(quan)(quan)(quan)(quan)小組(zu)組(zu)長及(ji)(ji)安(an)(an)全(quan)(quan)(quan)(quan)員、質檢員等進行驗收，自檢合格(ge)后(hou)報(bao)請監理單(dan)位進行驗收，驗收合格(ge)后(hou)方可進行使用(yong)。
