井(jing)周分層回填，回填時(shi)夯實兩邊填料，動(dong)作不(bu)能(neng)過猛，以免擠壞管道接口，而(er)且應盡量沿管對稱(cheng)填筑，該部(bu)(bu)分的(de)(de)密實度(du)應達到設計(ji)及(ji)規(gui)范要求。在程(cheng)(cheng)(cheng)序設計(ji)中，為完成(cheng)某一(yi)功(gong)能(neng)所需的(de)(de)一(yi)段(duan)程(cheng)(cheng)(cheng)序或(huo)(huo)子(zi)程(cheng)(cheng)(cheng)序;或(huo)(huo)指能(neng)由編(bian)譯程(cheng)(cheng)(cheng)序、裝配程(cheng)(cheng)(cheng)序等(deng)處理的(de)(de)獨(du)立程(cheng)(cheng)(cheng)序單(dan)位;或(huo)(huo)指大型軟(ruan)件系統的(de)(de)一(yi)部(bu)(bu)分。模塊，又(you)稱(cheng)構件，是能(neng)夠單(dan)獨(du)命名(ming)并獨(du)立地完成(cheng)一(yi)定(ding)功(gong)能(neng)的(de)(de)程(cheng)(cheng)(cheng)序語句(ju)的(de)(de)集合(即程(cheng)(cheng)(cheng)序代碼和數據結構的(de)(de)集合體)。它具有兩個基本(ben)的(de)(de)特征(zheng)：外部(bu)(bu)特征(zheng)和內(nei)部(bu)(bu)特征(zheng)。

用(yong)塑(su)料膜將混(hun)凝(ning)土(tu)覆蓋，預制砼井(jing)筒，以便養護(hu)(hu)。在后(hou)一(yi)道工(gong)(gong)序完成后(hou)，要(yao)用(yong)圍擋對(dui)檢(jian)(jian)查井(jing)周圍進行(xing)維護(hu)(hu)，防止過往(wang)車輛對(dui)井(jing)具進行(xing)撞擊，預制砼井(jing)筒廠(chang)商，對(dui)井(jing)具的位置(zhi)和高程破壞(huai)，待瀝(li)(li)青(qing)混(hun)凝(ning)土(tu)上面(mian)層(ceng)施(shi)工(gong)(gong)時再(zai)進行(xing)拆(chai)除。瀝(li)(li)青(qing)混(hun)凝(ning)土(tu)上面(mian)層(ceng)施(shi)工(gong)(gong)時，要(yao)用(yong)小型(xing)鋼輪壓路機對(dui)檢(jian)(jian)查井(jing)周圍反復進行(xing)碾壓，預制砼井(jing)筒批發商，確保(bao)檢(jian)(jian)查井(jing)周圍瀝(li)(li)青(qing)混(hun)凝(ning)土(tu)的密實度(du)。傳統(tong)的升井(jing)施(shi)工(gong)(gong)工(gong)(gong)藝不易于井(jing)筒質量(liang)控制，施(shi)工(gong)(gong)速度(du)慢，施(shi)工(gong)(gong)成品(pin)外觀(guan)質量(liang)差，質量(liang)上基本無法滿足大型(xing)機械(xie)在井(jing)邊碾壓施(shi)工(gong)(gong)，從(cong)而導致(zhi)建成后(hou)路面(mian)存在質量(liang)隱患。

當污泥(ni)(ni)淤(yu)積情況嚴重時(shi)(shi)，可(ke)將其抽取出(chu)然后(hou)進(jin)行(xing)清(qing)(qing)理(li)后(hou)再(zai)重新使(shi)(shi)用(yong)。當淤(yu)泥(ni)(ni)中(zhong)含有(you)較多(duo)的沙子(zi)、碎石(shi)等雜質，則可(ke)采取將其撈出(chu)并進(jin)行(xing)清(qing)(qing)理(li)后(hou)再(zai)使(shi)(shi)用(yong)。 當污泥(ni)(ni)中(zhong)含有(you)較多(duo)的石(shi)塊(kuai)(kuai)、塑料(liao)袋等時(shi)(shi)，預制砼(tong)井筒生產廠家，可(ke)先將石(shi)塊(kuai)(kuai)或(huo)塑料(liao)袋等雜質打撈出(chu)來，再(zai)進(jin)行(xing)清(qing)(qing)洗并清(qing)(qing)理(li)干(gan)凈(jing)后(hou)再(zai)使(shi)(shi)用(yong)。當淤(yu)泥(ni)(ni)中(zhong)含有(you)大量(liang)的化學藥(yao)劑時(shi)(shi)，應(ying)先用(yong)清(qing)(qing)水(shui)沖(chong)洗干(gan)凈(jing)并進(jin)行(xing)沉淀，后(hou)再(zai)進(jin)行(xing)清(qing)(qing)理(li)。 同時(shi)(shi)可(ke)以在淤(yu)泥(ni)(ni)堆(dui)積處增(zeng)加反沖(chong)洗設(she)備(bei)或(huo)者(zhe)使(shi)(shi)用(yong)高壓水(shui)進(jin)行(xing)沖(chong)洗清(qing)(qing)理(li)，使(shi)(shi)污泥(ni)(ni)堆(dui)積現象得到有(you)效(xiao)改善。
