【正文】 coupling Centre shall be checked, the second poured concrete strength of more than 70%. In the process of reaming or boring, apart from the special provisions in factory, does not allow any work that may affect the coupling Centre, such as irrigation, to cylinder connections to flood the condenser pipes and so on. Well boring, hinge bolt hole flange with coupling of vertical, not oblique. Mounting bolts should be added lubricants, typing gently with a small hammer, not too loose or too tight, packed the bolts with the corresponding seal screw hole should be marked. coupling reamed and pairings is close to the diameter of bolt bearing good hinge holes, dressed with a good two coupling bolts before you can move the rotor, boringreaming hole in turn. Coupling bolts must be tight coupling is symmetrical diameter, in boring, reaming, two bolts out. Well boring, hinge bolt hole flange with coupling of vertical, not oblique. Due to the coupling bolts in accordance with hinge holes corresponding to the diameter of the screw holes one by one after processing, processing back bolt installation location cannot be changed, so according to bolt after the actual weight difference of nut and lock washer to match. General requirements for coupling two symmetrical diameter bolt, nut and lock washer39。第四系全新統(tǒng)沖積層厚度約25～50m，巖性主要為黏土、粉質(zhì)黏土、粉土、粉砂、細(xì)砂；第四系上更新統(tǒng)沖積層厚度大于50m，巖性主要為黏性土、粉土、粉細(xì)砂等。（1）遵守國(guó)家保護(hù)法規(guī),加強(qiáng)環(huán)保意識(shí),對(duì)路基及用地界外的環(huán)境進(jìn)行保護(hù),不造成環(huán)境污染.（2）做好排水系統(tǒng),防止路基水土流失。（3）施工現(xiàn)場(chǎng)配備足夠的消防器材，并指定專(zhuān)人維護(hù)、管理、定期更新，保證正常使用。（2）施工現(xiàn)場(chǎng)設(shè)設(shè)立醒目的安全生產(chǎn)宣傳標(biāo)語(yǔ)和勞動(dòng)保護(hù)標(biāo)志，設(shè)備、機(jī)械、電器上都標(biāo)有操作規(guī)程和安全警示牌，施工操作時(shí)嚴(yán)格按照操作規(guī)程進(jìn)行。（2）安全生產(chǎn)技術(shù)保證措施中的各種安全防護(hù)措施的實(shí)施列入施工任務(wù)單，責(zé)任落實(shí)到班、組和個(gè)人。（2）施工中工程質(zhì)量實(shí)行“三檢制”，即：“自檢、互檢、交接檢”并做好記錄。堅(jiān)持“百年大計(jì)，質(zhì)量第一”的方針，樹(shù)立精品意識(shí)，確保工程質(zhì)量合格率達(dá)到100%。 填土?xí)r應(yīng)從構(gòu)筑物兩側(cè)均衡填筑，避免對(duì)構(gòu)筑物形成契行壓力。碾壓完成后，經(jīng)監(jiān)理檢驗(yàn)合格后方可進(jìn)行下一層施工。粗平完成后，使用平地機(jī)進(jìn)行細(xì)平，根據(jù)規(guī)范要求的平整度進(jìn)行整平。填土應(yīng)選用透水性良好的砂性土。試驗(yàn)臺(tái)背回填前進(jìn)行填料試驗(yàn)，對(duì)土源進(jìn)行現(xiàn)場(chǎng)調(diào)查、取樣試驗(yàn)，對(duì)填料進(jìn)行含水量、液限、塑限等項(xiàng)試驗(yàn)，確定土的最大干密度和最佳含水量.填料拌和施工時(shí)，取土場(chǎng)所取填料的含水量要求控制在合理范圍內(nèi)，現(xiàn)場(chǎng)根據(jù)填料情況調(diào)整施工含水量。(2)外圈定位行列和轉(zhuǎn)角石，應(yīng)選擇形狀較為方正及尺寸較大的片石，并長(zhǎng)短相間地與里層砌塊咬接。(4)各砌層的砌塊應(yīng)安放穩(wěn)固，砌塊間應(yīng)砂漿飽滿，粘結(jié)牢固，不得直接貼靠或脫空。(2)砌體應(yīng)分層砌筑，砌體較長(zhǎng)時(shí)可分段分層砌筑，；分段位置宜盡量設(shè)在沉降縫或伸縮縫處，各段水平砌縫應(yīng)一致。，不得倒置，按標(biāo)定的上下記號(hào)安放。104長(zhǎng)度（mm）+20，10尺量：抽查30%的板，每板檢查兩側(cè)，蓋板、涵臺(tái)、墩及支承面檢驗(yàn)必須合格，使其頂面標(biāo)高符合圖紙規(guī)定。54彎起鋼筋位置（mm）177。鋼筋實(shí)測(cè)項(xiàng)目項(xiàng)次檢 驗(yàn) 項(xiàng) 目規(guī)定值或允許偏差檢驗(yàn)頻率和方 法受力鋼筋間距基礎(chǔ)、墩臺(tái)、柱177。鋼筋在制作場(chǎng)內(nèi)集中下料制作、加工綁扎后堆放。 本涵蓋板鋼筋骨架由φ2φ12（HRB335），φ8（R235）鋼筋組成，模板采用組合鋼模板，共用99cm矩形板27塊，異形蓋板2塊。并做到及時(shí)清理、維修和涂刷好隔離劑，以備待用。拆模時(shí)，嚴(yán)禁用大錘和撬棍硬砸硬撬。30水準(zhǔn)儀:測(cè)量58點(diǎn)5軸線
