沉井制作前應作好下列準備工作：（1）對施工場地進行勘察，查清和排除地面及地面3m以內(nèi)的障礙物(如房屋構筑物、管道、樹根、電纜線路等)。（2）熟悉工程地質、水文地質、施工圖紙等資料，熟悉場地的地質情況、地下水情況以及地下障礙物情況等。（3）施工前，應在沉井施工地點進行鉆孔。（4）敷設水電管線、修筑臨時道路，平整場地，即三通一平；搭建必要的臨時設施，集中必要的材料、機具設備和勞動力。（5）根據(jù)工程結構特點、地質水文情況、施工設備條件、技術的可能性，編制切實可行的施工方案或施工技術措施施工組織設計及施工方案的基本概念1、施工組織總設計（generalconstructioanizationplan）以若干單位工程組成的群體工程或特大型項目為主要對象編制的施工組織設計，對整個項目的施工過程起統(tǒng)籌規(guī)劃、重點控制的作用。2、單位工程施工組織設計。市政工程包含的類別比較多，主要類別有：1、鐵路、道路、高速公路，城市道路極其橋涵、停車場等附屬設施。2、市政管線，供水管、排水管，電力線路，電訊線路，燃氣管道等附屬設施；3、機場有關等設施。4、河道、碼頭及附屬設施等；5、防洪工程、水利工程、地下曲水工程等。6、人防等地下空間工程等；7、無線電塔工程等。在沉箱病的防治上有了新的改進，使得氣壓沉箱這一古老的施工技術得到了新生。五河沉井墊木布置</p><p style="text-indent:25px">沉井與沉箱整體剛度大，抗震性好；五河沉井刃腳</p><p> 使不產(chǎn)生過大傾斜。各倉土面高差應在50cm以內(nèi)。4．在挖土下沉過程中，工長、測量人員、挖土工人應密切配合，加強觀測，及時糾偏。5．沉井下沉多采用排水挖土下沉方法，常用方法是：設明溝、集水井排水，在沉井內(nèi)離刃腳2～3m挖一圈排水明溝，設3～4個集水井，深度比開挖面底部低1．0～1．5m，溝和井底深度隨沉井挖土而不斷加深。在井壁上設離心式水泵或井內(nèi)設潛水泵，將地下水排出井外。當?shù)刭|條件較差，有流砂發(fā)生的情況，可在沉井外部周圍設置輕型井點、噴射井點或深井井點以降低地下水位，或采用井點與明溝排水相結合的方法進行降水。6．沉井下沉觀測方法為在沉井外壁周圍彈水平線，井筒內(nèi)按4等分或8等分標出垂直軸線，各吊線墜一個，對準下部標板來控制。觀測時間，每班三次，接近設計標高時兩小時一次。隨時掌握分析觀測數(shù)值，當線墜偏離垂線達50mm或標高差在100mm，應立即糾正。挖土過程中可通過調(diào)整挖土標高或勞動力進行糾偏。7．筒壁下沉時，外測土會隨之出現(xiàn)下陷，與筒壁間形成空隙，一般干筒壁外側填砂，保持不少于30cm高，隨下沉灌入空隙中，以減小下沉的摩阻力，并減少了以后的清淤工作。雨季應在填砂外側作擋水堤，以阻止雨水進入空隙。五河沉井刃腳</p><p
