使不產(chǎn)生過大傾斜。各倉土面高差應(yīng)在50cm以內(nèi)。4．在挖土下沉過程中，工長、測(cè)量人員、挖土工人應(yīng)密切配合，加強(qiáng)觀測(cè)，及時(shí)糾偏。5．沉井下沉多采用排水挖土下沉方法，常用方法是：設(shè)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(shè)3～4個(gè)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(shè)離心式水泵或井內(nèi)設(shè)潛水泵，將地下水排出井外。當(dāng)?shù)刭|(zhì)條件較差，有流砂發(fā)生的情況，可在沉井外部周圍設(shè)置輕型井點(diǎn)、噴射井點(diǎn)或深井井點(diǎn)以降低地下水位，或采用井點(diǎn)與明溝排水相結(jié)合的方法進(jìn)行降水。6．沉井下沉觀測(cè)方法為在沉井外壁周圍彈水平線，臨泉市政道路沉井，井筒內(nèi)按4等分或8等分標(biāo)出垂直軸線，各吊線墜一個(gè)，對(duì)準(zhǔn)下部標(biāo)板來控制。觀測(cè)時(shí)間，每班三次，接近設(shè)計(jì)標(biāo)高時(shí)兩小時(shí)一次。隨時(shí)掌握分析觀測(cè)數(shù)值，臨泉市政道路沉井，當(dāng)線墜偏離垂線達(dá)50mm或標(biāo)高差在100mm，應(yīng)立即糾正。挖土過程中可通過調(diào)整挖土標(biāo)高或勞動(dòng)力進(jìn)行糾偏。7．筒壁下沉?xí)r，外測(cè)土?xí)S之出現(xiàn)下陷，與筒壁間形成空隙，一般干筒壁外側(cè)填砂，保持不少于30cm高，隨下沉灌入空隙中，臨泉市政道路沉井，以減小下沉的摩阻力，并減少了以后的清淤工作。雨季應(yīng)在填砂外側(cè)作擋水堤，以阻止雨水進(jìn)入空隙。中心島式下沉：為將施工引起的地表沉降對(duì)周圍建筑物影響降至**小，可考慮采用中心島式下沉工藝.臨泉市政道路沉井</p><div

1.井壁：沉井的外壁，是沉井的主要部分，它應(yīng)有足夠的強(qiáng)度，以便承受沉井下沉過程中及使用時(shí)作用的荷載；同時(shí)還要求有足夠的重量，使沉井在自重作用下能順利下沉 </p> <p> 2.刃腳：井壁下端一般都做成刀刃狀的“刃腳”，其功用是減少下沉阻力 </p> <p> 3.隔墻：設(shè)置在沉井井筒內(nèi)，其主要作用是增加沉井在下沉過程中的剛度，同時(shí)，又把整個(gè)沉井分隔成多個(gè)施工井孔(取土井)，使挖土和下沉可以較均衡地進(jìn)行，也便于沉井偏斜時(shí)的糾偏 </p> <p> 4.凹槽：設(shè)置在刃腳上方井壁內(nèi)側(cè)，其作用時(shí)使封底混凝土和底板與井壁間有更好的聯(lián)結(jié)，以傳遞基底反力 </p> <p> 5.封底：當(dāng)沉井下沉到設(shè)計(jì)標(biāo)高，經(jīng)過技術(shù)檢驗(yàn)并對(duì)井底清理整平后，即可封底，以防止地下水滲入井內(nèi) </p> <p> 6.頂蓋：井頂澆筑鋼筋混凝土頂蓋，待頂蓋達(dá)到設(shè)計(jì)強(qiáng)度后方可砌筑墩。臨泉排水泵站沉井2007年，我國傳統(tǒng)的氣壓沉箱技術(shù)進(jìn)行集成創(chuàng)新，采用國內(nèi)自主研發(fā)的氣壓沉箱無人化遙控施工系統(tǒng).</p><div style="width:100%;text-align: center;"><img
