Therefore, TXX12 (124t) with maximum weight is adopted to carry out this calculation.

When the tank body is lifted every 30mm height, the person shall be responsible for checking the hoisting of tank wall to ensure that the lifting speed is consistent in all directions and to keep the lifting as consistent as possible. The time spent on lifting individual ring depends on tank size, weight. Generally speaking: if the tank diameterφ≤16 meters, and each pulley loading smaller than 1/3 of maximum loading, it shall cost 2 hours for hoisting one ring。One gantry plate shall be set up at each side of post, 500mm away from the center of post. Other gantry plates shall be set at 1500mm intervals.Installation and lifting of tank shell plates。脹緊后在脹圈千斤頂接頭的兩側(cè)各用一個(gè)傳力筋板（龍門板）扣住分別焊在罐壁上，并用銷子與罐壁打?qū)?。After all the following work has been done and checked out: base plate of the tank has been surface treated for anticorrosion and laid out, welded and installed。墊板與底板點(diǎn)焊，在其上表面劃出壁板安裝線，在線兩側(cè)點(diǎn)焊擋板。這樣布置既可使單個(gè)立柱有足夠的剛度，又使所有立柱形成封閉系統(tǒng)，充分保證立柱組成的提升系統(tǒng)的穩(wěn)定性。――手拉葫蘆起重折減系數(shù)，取167。Prepare tools used in the construction such as gantry plates, pins, small hammer, large hammer, sample plates, etc. The specification of liner plate for post is 400x400x12. 手拉葫蘆數(shù)量的確定Decide the quantity of manual pulleys 選用各儲(chǔ)罐所需要的手拉葫蘆載荷量Select the load of manual pulley required by each tank 手拉葫蘆數(shù)量的確定主要依據(jù)手拉葫蘆的承載能力和提升儲(chǔ)罐最后提升的最大載荷。各大段之間采用手壓千斤頂脹緊在罐壁上。The numbers of tanks using flip chip construction with manual pulley hoisting are in the order of: TXX6TXX6TXX70、TXX0TXX0TXX0TXX0TXX0TXXTXX1TXX12A、TXX12B、TXX12C 、TXX1TXX1TXX1TXX2TXX01A、TXX01B、TXX0TXX0TXX0TXX5TXXTXXTXX50 Total 26。手拉葫蘆提升倒裝施工方案Chain Block Inverse Installation Construction Procedure目錄Contents1. 工程概述 3Project profile 32. 工程內(nèi)容 3Project contents 33. 手拉葫蘆提升倒裝法施工技術(shù)施工順序 3Construction order of flip chip construction technology with manual pulley hoisting 34. 手拉葫蘆提升裝置的準(zhǔn)備 5The preparation of manual pulley hoisting device 55. 手拉葫蘆立柱的平面布置說明 9Plane layout instructions of manual pulley posts 9……………………………………………………………..10 Installation
