長春水泥管的安裝施工(gong)建(jian)議(yi):1、定(ding)管道中線： 施工(gong)前可按設(she)計給定(ding)的中線控制點(dian)(dian)(dian)(dian)，在現場測設(she)出中線的起(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(zhi)線控制中心樁，并(bing)在起(qi)點(dian)(dian)(dian)(dian)、終(zhong)點(dian)(dian)(dian)(dian)平(ping)面點(dian)(dian)(dian)(dian)的溝槽外適當位(wei)置(zhi)，設(she)置(zhi)方向控制樁，并(bing)且(qie)通過丈量確定(ding)樁號。 2、建(jian)立臨(lin)時(shi)水(shui)準(zhun)點(dian)(dian)(dian)(dian)： 管道工(gong)程(cheng)往往需增設(she)臨(lin)時(shi)水(shui)準(zhun)點(dian)(dian)(dian)(dian)，應在穩固且(qie)不(bu)易被(bei)碰撞處設(she)置(zhi)，其間距為不(bu)大于(yu)30米為宜。臨(lin)時(shi)水(shui)準(zhun)點(dian)(dian)(dian)(dian)閉合(he)差(cha)應符合(he)規定(ding)標準(zhun)。
3、溝槽(cao)(cao)開挖采用(yong)挖掘機開挖為主，人工清底(di)(di)(di)為輔(fu)，雨(yu)水斗連接管及(ji)(ji)支(zhi)管采用(yong)人工開挖。開挖過程(cheng)中，注意觀(guan)察土質變化，對有塌方跡象(xiang)的路段采用(yong)支(zhi)撐圍護。 4、挖掘機開挖挖至槽(cao)(cao)底(di)(di)(di)標高(gao) 10cm左右，預留槽(cao)(cao)底(di)(di)(di)土不挖，修整(zheng)槽(cao)(cao)底(di)(di)(di)。人工清槽(cao)(cao)，認真檢查槽(cao)(cao)底(di)(di)(di)土壤有無擾動情況，如有擾動應(ying)做(zuo)特殊處(chu)理。 5、在溝槽(cao)(cao)兩側，槽(cao)(cao)底(di)(di)(di)以上1米處(chu)，對稱設(she)置高(gao)程(cheng)樁，在其上釘(ding)等高(gao)的高(gao)程(cheng)釘(ding)。在挖槽(cao)(cao)見底(di)(di)(di)前及(ji)(ji)澆筑平整(zheng)前，均應(ying)復(fu)測(ce)管渠(qu)中心線及(ji)(ji)高(gao)程(cheng)樁的高(gao)程(cheng)。
6、槽(cao)邊單(dan)面堆土高度不大(da)于2米(mi)，距溝(gou)槽(cao)邊緣距離(li)不小于1米(mi)。溝(gou)槽(cao)施(shi)工地(di)下管(guan)線(xian)(xian)的(de)保(bao)(bao)護先向(xiang)有關部門要求管(guan)線(xian)(xian)交底，以(yi)明確地(di)下設施(shi)的(de)基本位置，必要時先開(kai)挖樣洞，以(yi)探明準確位置，利于施(shi)工，并保(bao)(bao)證各種預埋管(guan)線(xian)(xian)的(de)安(an)全(quan)，施(shi)工過程(cheng)中，對(dui)暴(bao)露的(de)管(guan)線(xian)(xian)采用支撐(cheng)保(bao)(bao)護措(cuo)施(shi)。
