長春水泥制品廠分享承(cheng)(cheng)插式水泥管(guan)(guan)(guan)的施工建議(yi)，在(zai)鋪設管(guan)(guan)(guan)道(dao)(dao)前(qian)，檢(jian)查(cha)樣板標(biao)高，確定(ding)管(guan)(guan)(guan)段(duan)中心線，管(guan)(guan)(guan)道(dao)(dao)位(wei)置(zhi)，設置(zhi)墊(dian)板標(biao)高。配管(guan)(guan)(guan)順序應(ying)(ying)從(cong)下游到上(shang)游，承(cheng)(cheng)口到上(shang)游。龍(long)頭(tou)為下游方(fang)向，回水井與管(guan)(guan)(guan)道(dao)(dao)的連接處采(cai)用半(ban)節短管(guan)(guan)(guan)。插座應(ying)(ying)布置(zhi)在(zai)地(di)窖(jiao)井的進水方(fang)向，龍(long)頭(tou)應(ying)(ying)布置(zhi)在(zai)客艙的出水方(fang)向。鋪設管(guan)(guan)(guan)道(dao)(dao)前(qian)，用鋼絲刷清(qing)潔承(cheng)(cheng)口內表面和承(cheng)(cheng)口外表面，清(qing)油污和雜物。根據管(guan)(guan)(guan)徑(jing)規格(ge)選(xuan)擇相應(ying)(ying)的橡膠密封(feng)圈套入(ru)承(cheng)(cheng)口槽內。要求(qiu)四周均勻、光滑、不(bu)變形，膠圈表面和前(qian)管(guan)(guan)(guan)內表面涂防水涂層，防止滲水。
下(xia)管(guan)(guan)(guan)(guan)(guan)(guan)時，起吊(diao)(diao)點(dian)應設在管(guan)(guan)(guan)(guan)(guan)(guan)子的(de)重心處，用吊(diao)(diao)具(ju)提腰(yao)，或使用專用吊(diao)(diao)具(ju)。禁止采(cai)用鋼索(suo)穿(chuan)管(guan)(guan)(guan)(guan)(guan)(guan)的(de)方法(fa)。起吊(diao)(diao)管(guan)(guan)(guan)(guan)(guan)(guan)道時，防止損壞(huai)管(guan)(guan)(guan)(guan)(guan)(guan)接頭(tou)(tou)的(de)接頭(tou)(tou)。鋪設管(guan)(guan)(guan)(guan)(guan)(guan)道時，將管(guan)(guan)(guan)(guan)(guan)(guan)段(duan)(duan)平(ping)穩地垂下(xia)，移至管(guan)(guan)(guan)(guan)(guan)(guan)子的(de)接頭(tou)(tou)處，調整(zheng)管(guan)(guan)(guan)(guan)(guan)(guan)段(duan)(duan)的(de)標高和軸線，然后用管(guan)(guan)(guan)(guan)(guan)(guan)子緊固裝置將管(guan)(guan)(guan)(guan)(guan)(guan)子的(de)承口慢慢插入承口。在插管(guan)(guan)(guan)(guan)(guan)(guan)過(guo)程中，管(guan)(guan)(guan)(guan)(guan)(guan)段(duan)(duan)仍(reng)需懸空(kong)，以(yi)減少(shao)管(guan)(guan)(guan)(guan)(guan)(guan)子上緊時的(de)張力(li)。
管(guan)段(duan)擰緊后(hou)(hou)，調(diao)整管(guan)子(zi)軸線和(he)標高(gao)，然后(hou)(hou)用管(guan)枕壓實。插入管(guan)段(duan)時，注意橡(xiang)膠圈不要出現(xian)扭曲或滑動。 管(guan)道胸腔回(hui)(hui)填(tian)：材料用粗黃砂或石屑(xie)填(tian)滿(man)凹槽進行回(hui)(hui)填(tian)，回(hui)(hui)填(tian)高(gao)度與管(guan)道中心齊平。
