長春水泥管的(de)(de)安(an)裝(zhuang)施工(gong)建(jian)(jian)議:1、定(ding)管道中(zhong)線： 施工(gong)前可按設計給(gei)定(ding)的(de)(de)中(zhong)線控(kong)制(zhi)點(dian)(dian)(dian)(dian)，在現場測設出中(zhong)線的(de)(de)起(qi)點(dian)(dian)(dian)(dian)、終(zhong)點(dian)(dian)(dian)(dian)、平(ping)面 點(dian)(dian)(dian)(dian)、縱向點(dian)(dian)(dian)(dian)及直線控(kong)制(zhi)中(zhong)心樁，并在起(qi)點(dian)(dian)(dian)(dian)、終(zhong)點(dian)(dian)(dian)(dian)平(ping)面點(dian)(dian)(dian)(dian)的(de)(de)溝(gou)槽外適當位置，設置方(fang)向控(kong)制(zhi)樁，并且通過丈(zhang)量確(que)定(ding)樁號。 2、建(jian)(jian)立(li)臨(lin)(lin)時(shi)水準點(dian)(dian)(dian)(dian)： 管道工(gong)程(cheng)往(wang)往(wang)需增設臨(lin)(lin)時(shi)水準點(dian)(dian)(dian)(dian)，應(ying)在穩固且不易被碰撞處設置，其間距為(wei)(wei)不大于30米為(wei)(wei)宜(yi)。臨(lin)(lin)時(shi)水準點(dian)(dian)(dian)(dian)閉合(he)差應(ying)符合(he)規定(ding)標準。
3、溝槽(cao)(cao)開(kai)挖(wa)(wa)采(cai)用挖(wa)(wa)掘機開(kai)挖(wa)(wa)為主，人(ren)(ren)工(gong)(gong)清(qing)底(di)(di)為輔，雨水斗(dou)連(lian)接(jie)管及(ji)支(zhi)管采(cai)用人(ren)(ren)工(gong)(gong)開(kai)挖(wa)(wa)。開(kai)挖(wa)(wa)過程中，注意觀察土(tu)質變化，對有(you)(you)塌方跡象(xiang)的路段采(cai)用支(zhi)撐(cheng)圍護。 4、挖(wa)(wa)掘機開(kai)挖(wa)(wa)挖(wa)(wa)至(zhi)槽(cao)(cao)底(di)(di)標高(gao)(gao) 10cm左右，預留(liu)槽(cao)(cao)底(di)(di)土(tu)不(bu)挖(wa)(wa)，修整槽(cao)(cao)底(di)(di)。人(ren)(ren)工(gong)(gong)清(qing)槽(cao)(cao)，認真(zhen)檢查槽(cao)(cao)底(di)(di)土(tu)壤有(you)(you)無擾動情況，如有(you)(you)擾動應(ying)做特殊處(chu)理。 5、在溝槽(cao)(cao)兩側，槽(cao)(cao)底(di)(di)以上1米處(chu)，對稱設置高(gao)(gao)程樁(zhuang)，在其(qi)上釘(ding)等(deng)高(gao)(gao)的高(gao)(gao)程釘(ding)。在挖(wa)(wa)槽(cao)(cao)見底(di)(di)前及(ji)澆筑(zhu)平整前，均應(ying)復測管渠中心線及(ji)高(gao)(gao)程樁(zhuang)的高(gao)(gao)程。
6、槽邊單面堆土(tu)高(gao)度不大于2米，距(ju)溝槽邊緣距(ju)離不小于1米。溝槽施(shi)工地(di)下(xia)管(guan)(guan)線的(de)保(bao)護先向(xiang)有關部門要(yao)求管(guan)(guan)線交底，以明(ming)確地(di)下(xia)設施(shi)的(de)基本位置(zhi)，必要(yao)時先開挖(wa)樣洞，以探明(ming)準確位置(zhi)，利于施(shi)工，并保(bao)證各種預埋管(guan)(guan)線的(de)安全，施(shi)工過程中，對暴露的(de)管(guan)(guan)線采用支撐(cheng)保(bao)護措施(shi)。
