長春檢查井地基(ji)與基(ji)礎(chu)施工建議井底座的磚、石等(deng)應清除(chu)，成品雨水(shui)檢(jian)查井，沿管道方向(xiang)(xiang)及(ji)沿管道垂直方向(xiang)(xiang)不(bu)小(xiao)于檢(jian)查井直徑400mm的基(ji)礎(chu)尺寸用中粗砂(sha)鋪墊、攤平、夯(hang)實(shi)，當井底座被水(shui)浸泡，應將水(shui)排除(chu)，清除(chu)被浸泡的土層。
建議用中粗砂換填并夯實，復核井(jing)底(di)座編號(hao)、規格、接管(guan)直徑(jing)，混凝(ning)土(tu)檢(jian)查井(jing)廠家，井(jing)底(di)座安(an)(an)裝(zhuang)中心定位(wei)后，將檢(jian)查井(jing)的井(jing)底(di)座安(an)(an)置于井(jing)底(di)坑基礎上。并調整好井(jing)底(di)座標高和接管(guan)位(wei)置。
工(gong)(gong)序(xu)為：井(jing)→管(guan)(guan)(guan)(guan)(guan)(guan)→井(jing)→管(guan)(guan)(guan)(guan)(guan)(guan)。 檢查井(jing)的(de)安(an)裝應(ying)先從接(jie)戶管(guan)(guan)(guan)(guan)(guan)(guan)上段開始安(an)，以井(jing)-管(guan)(guan)(guan)(guan)(guan)(guan)-井(jing)-管(guan)(guan)(guan)(guan)(guan)(guan)順(shun)序(xu)依次進行(xing)安(an)裝，并逐漸向下延(yan)伸，當變(bian)徑(jing)的(de)時候，如果(guo)匯入(ru)管(guan)(guan)(guan)(guan)(guan)(guan)徑(jing)小于井(jing)座(zuo)接(jie)口管(guan)(guan)(guan)(guan)(guan)(guan)徑(jing)，應(ying)采取(qu)管(guan)(guan)(guan)(guan)(guan)(guan)頂平(ping)接(jie)的(de)方(fang)式；如果(guo)井(jing)座(zuo)排出(chu)管(guan)(guan)(guan)(guan)(guan)(guan)接(jie)口大(da)于下游管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)徑(jing)，就采取(qu)管(guan)(guan)(guan)(guan)(guan)(guan)內(nei)底平(ping)接(jie)的(de)方(fang)式。 安(an)裝附加接(jie)頭(tou)時，應(ying)根(gen)據井(jing)筒(tong)尺(chi)寸和連接(jie)管(guan)(guan)(guan)(guan)(guan)(guan)道(dao)直(zhi)徑(jing)來(lai)進行(xing)安(an)裝前(qian)的(de)測量工(gong)(gong)作，并且(qie)采用(yong)專用(yong)工(gong)(gong)具在井(jing)壁(bi)上開孔，注意安(an)裝附加接(jie)頭(tou)不得倒坡(po)。
