【摘要】：在貴港航運(yùn)樞紐工程大型啟閉機(jī)PT平臺(tái)梁的預(yù)制與吊裝施工中，根據(jù)預(yù)制件體積大、重量重、吊裝技術(shù)要求高的特點(diǎn)，，因地制宜，采用了合理的預(yù)制平臺(tái)和吊裝施工技術(shù)．預(yù)制平臺(tái)位置的選擇要在壩頂永久門機(jī)起吊范圍內(nèi)；預(yù)制平臺(tái)的搭設(shè)要避開壩頂施工門機(jī)的干擾；嚴(yán)把平臺(tái)模板和鋼筋制安質(zhì)量關(guān)；嚴(yán)格控制混凝土澆筑；合理選用吊裝銅絲繩；對(duì)抓染及PT平臺(tái)梁棱角采取保護(hù)措施；吊裝工序按穿繞銅絲繩→卸扣連接→棱角保護(hù)→繩扣檢查→試吊→緩慢行走及提升→支座墊層安裝→就位→檢查合格→脫鉤進(jìn)行．實(shí)踐證明效果良好．
[Abstract]:In the prefabrication and hoisting construction of PT platform beam of large-scale hoist in Guigang Shipping Hub Project, according to the characteristics of large volume, heavy weight and high requirements of hoisting technology of prefabricated parts, measures should be taken according to local conditions. Reasonable prefabricated platform and hoisting construction technology are adopted. The selection of prefabricated platform location should be within the lifting range of permanent portal crane at dam top, the erection of prefabricated platform should avoid the interference of dam top construction door crane, the safety quality of platform formwork and steel bar should be strictly controlled; Strictly control concrete pouring; reasonably select hoisting copper wire rope; take protective measures to catch dyeing and PT platform beam angle; hoisting process according to the winding copper wire rope. 鈫扵ripping connection. 鈫扐ngular protection. 鈫扲ope buckle inspection. 鈫扵est crane. 鈫扴low walking and lifting. 鈫払earing cushion installation. 鈫捍n position. 鈫捍nspection pass. 鈫扵he effect of decoupling is proved to be good in practice.
