沉井施工步驟：1.場(chǎng)地平整，鋪墊木、制作底節(jié)沉井2.拆模，刃腳下一邊填塞砂、一邊對(duì)稱(chēng)抽拔出墊木3.均勻開(kāi)挖下沉沉井，底節(jié)沉井下沉完畢4.建筑第二節(jié)沉井，繼續(xù)開(kāi)挖下沉并接筑下一節(jié)井壁5.下沉至設(shè)計(jì)標(biāo)高，清基6.沉井封底處理7.施工井內(nèi)設(shè)計(jì)和封頂?shù)榷x：沉井是井筒狀的結(jié)構(gòu)物，它是以井內(nèi)挖土，依靠自身重力克服井壁摩阻力后下沉到設(shè)計(jì)標(biāo)高，然后經(jīng)過(guò)混凝土封底并填塞井孔，使其成為橋梁墩臺(tái)或其它結(jié)構(gòu)物的基礎(chǔ)。一般在施工大型橋墩的基坑，污水泵站，大型設(shè)備基礎(chǔ)，人防掩蔽所，盾構(gòu)拼裝井，地下車(chē)道與車(chē)站水工基礎(chǔ)施工圍護(hù)裝置時(shí)使用。一、沉井的主要施工程序：（一）沉井制作1．在軟弱地基上制作沉井，應(yīng)采用砂、砂礫或碎石墊層，用打夯機(jī)夯實(shí)使之密實(shí)，厚度根據(jù)計(jì)算確定。2．當(dāng)?shù)鼗临|(zhì)較好，宜分節(jié)一次制作完成，然后下沉；對(duì)于較高（≥12m）的沉井應(yīng)先挖下3～4m土方，在基坑中一次制作下沉，或分節(jié)制作，分節(jié)下沉，以減少沉井自由高度，增加穩(wěn)定，防止傾斜。3．沉井制作宜采取在刃腳下設(shè)置木墊架或磚墊座的方法，其大、小和間距應(yīng)根據(jù)荷重計(jì)算確定。安設(shè)鋼刃腳時(shí)，要確保外側(cè)與地面垂直，以使其起切土導(dǎo)向作用。</p><p> 本來(lái)看似是不同的施工，但是其本質(zhì)可以說(shuō)是一回事，其原理都是將管內(nèi)（包括圓管和方管）的土體挖出而將管內(nèi)外壁雙側(cè)摩擦力變成管外壁單側(cè)摩擦力，并且在后方施加頂力而達(dá)到穿越土層的目的。箱涵可以看成是矩形的頂管。沉井可以看成是將水平的頂管立起來(lái)。而沉井的自重就相當(dāng)于頂管的千斤頂頂力。 </p> <p> <br /> </p> <p> 箱涵施工工藝流程： </p> <p> 現(xiàn)場(chǎng)調(diào)查→工程降水→工作坑開(kāi)挖→后背制作→滑板制作→鋪設(shè)潤(rùn)滑隔離層→箱涵制作→頂進(jìn)設(shè)備安裝→既有線加固→箱涵試頂進(jìn)→吃土頂進(jìn)→監(jiān)控量測(cè)→箱體就位→拆除加固設(shè)施→拆除后背及頂進(jìn)設(shè)備→工作坑恢復(fù)。 </p> <p> <br /> </p> <p> 沉井施工工藝流程： </p> <p> 場(chǎng)地整平→放線→挖土600～700mm深→夯實(shí)基底→抄平放線驗(yàn)線→鋪砂墊層→墊木或挖刃腳土模→安設(shè)刃腳鐵件、綁鋼筋→支刃腳、井身模板→澆筑混凝土→養(yǎng)護(hù)、拆模→**圍槽灌砂→抽出墊木或拆磚座。 20世紀(jì)50年代，我國(guó)已將該技術(shù)應(yīng)用于各項(xiàng)工程中，其體積從直徑*2m的集水井到巨大的泰州長(zhǎng)江大橋中塔沉井.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
