【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、粉細砂等。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、粉細砂等。一旦發(fā)生危害工程和人身、財產(chǎn)安全的事故時，施工處在采取必要的搶險補救措施的同時應(yīng)立即暫停此項目和與之相關(guān)的項目的施工，保護好事故現(xiàn)場，因搶救人員、疏導(dǎo)交通等原因，需移動現(xiàn)場物件時，應(yīng)做好標記，并應(yīng)采取拍照或錄像等直接方式反映現(xiàn)場原狀。十二、質(zhì)量、安全、環(huán)保應(yīng)急預(yù)案1）基坑坍塌2）觸電事故3）可能出現(xiàn)的安全生產(chǎn)事故4）臺風、汛情等氣象性災(zāi)害迅速搶險救助、妥善保護現(xiàn)場。所施工的不同標號，均由攪拌站統(tǒng)一制備，采用專業(yè)砼運輸車送至施工現(xiàn)場。，進入工地的工程用料，必須具有出廠合格證，檢驗合格證，質(zhì)量保證書，并進行抽樣試驗，確保材料質(zhì)量符合設(shè)計要求。，適當召開質(zhì)量分析會議。十、技術(shù)措施，并及時與監(jiān)理工程師取得聯(lián)系，辦理有關(guān)簽證手續(xù)，做到各項施工監(jiān)理工程師滿意。對于施工中廢棄的零碎配件，邊角料、水泥袋、包裝箱等及時收集清理并搞好現(xiàn)場衛(wèi)生，以保護自然環(huán)境與景觀不受破壞。（2）施工和生活中的廢棄物也可經(jīng)當?shù)丨h(huán)保部門同意后，運至指定地點，此外，工地設(shè)置能沖洗的廁所，派專門的人員清理打掃，并定期對周圍噴藥消毒，
