General rules, spherical before installation foundation intensity should achieve design strength value of 75 % above. After the declaration, civil organizations apply for general supervision by the owner, inspection, contact joint field measurement installed in accordance with the standards of foundation, elevation, anchor bolt hole deviation and position in the center circle as the confirmation, such as the qualified, sign on the spot. The plate and shell parts: (1) receive reinspection plate and shell parts to on-site inspection and imported goods, after construction units inspected. (2) shell plates. According to the drawing and construction unit of relevant standards and spherical shell plates by zhang check surface quality and the arc length measurement and curvature. After checking that two spherical surface quality of the north, and a small reservoirs in tuen mun qualified the 4 billiards shell plate surface has scratches, rust and curvature, dimensions, such as necked-down situation. CMP company, except this measurement results, and puts forward corresponding to accept the penalty spot and promised to repair, repair plan to repair, the construction unit testing, finally, VT MT by special inspection center for acceptance. (3) spherical shell thickness of plates. Construction unit by random 20 %, the platform with 20 S14 quenched the equator at first 300mm board thickness, Yang CMP company 42mm than in board, make initiative S14 sphericalDelay 3 months. (4) shell plates ultrasonic testing. According to GB50094 standard, construction units of spherical shell by the board of 100 % of the deck and the board surrounding ultrasonic testing, the results are all qualified. Installation: pillar of spherical pillar, the two points in the period of pillar has welded plate, site installation is under section pillars based on lifting to spherical first, then use the scaffold fluctuation two together. Before installation should be under section pillars, based on measuring spherical elevation based on each floor made pillars round and setting-out lofting, then use the circle diagram inclined mat iron group trentment paving the adjacent base. When the hoisting, adjust the pillar of perpendicular to the equator (this is the group with smooth, field observation or vertical deviation is less GB12337 and GB50094 15mm, conform to requirements. 14 after all the pillars shall be installed, in order to ensure the timely follow-up scaffold built with the installation. Spherical shell plates orientation block welding and put in: (1) the orientation block welding. Spherical shell board after inspection by Numbers, and according to all take place in welding assembling positioning, lug (weld positioning, etc must be lifting lugs according to the process of qualified standard welding process evaluation, etc.) for the main assembly method, using pot in the zone, with using orientation block, lifting lugs, etc, in the temperate zone, has brought under used orientation block, lifting lugs on board inside such welding. Spherical shell plates put in place. Using crane "dumped" will bring down the temperate zone, has placed on board by lifting is based on the sphere, temperate, around the equator, put in the distance were extremely belt around the basis for crane (channel). Equatorial belt of the assembly: the entire assembly is quenched the benchmark, the assembly assembled in the upper section pillars installation position, therefore, must be adjusted under the premise of good prop perpendicularity. (1) the equatorial plate installation with pillar. According to the lifting up beforehand, in order for two mouth place row, pillar centerline of midline by two pillars in various welding joint bolt hole plate localization, with three of the pillar in the equatorial plate welding wire rope lug hanging. The first piece of equatorial plate with using rope drag after lift and the scaffold will two pillars of midline, according to tighten bolts, and pull the two wire and cable wind rope, fixed after the adjustment of vertical orientation; level (2) with the installation of the second pillar, and installed equatorial plate between two adjacent pillar lever, (3) without lifting a pillar of the equatorial plate, insert, first leg between two pieces of column, the use of longmen fixture adjust good clearance (5 + 2mm), pay attention to the curvature of the control, (4) using the above methods, informative, lifting a pillar of the equatorial plate with insert a piece, after which the equator without pillar, until the equatorial belt closed. When using the column leg braces and fixture in order to adjust the equator XiaXian level with the ellipse, clearance, the Angle, edges. Under the equatorial belt temperate assembly: after the assembly qualified under temperate assembly. Note that the equatorial belt and upper and lower temperate T seam between tank should be strictly monitor, the position of the temperate and under the compound with the transmission between used orientation block, lifting lugs on board, as the welding and temperate longitudinal seam orientation block, used in the plate welding lug etc. Besides the scaffold outside the tank, still need to set the bench in temporary support. Under the assembly sequence temperate (1) according to the equator, typesetting, spherical surface with a mouth on XiaXian in temperate, marked position next seam joint model T, and then lifting has put in the center of the sphere in the temperate zone under a spherical shell plates, (2) the first piece of hoisting plates and shells under the temperate ball room in longmen fastener tighten, then hold next temperate and equatorial belt welded plate shell, use lug guide plate chain adjustment shell, make its edges arc requirements, (3) under the hoisting temperate spherical shell with longmen fixture, from tank to the lock, medial longitudinal from tank lock mouth. Note the circular degree measuring hull plate and the Angle of edges, (4) in the temperate zone under the hoisting subsequent spherical shell plates. In order to prevent the shell plates, every three plate is using welding in equatorial belt on board the lug pull shell plates and guide chain adjustment, until the next temperate closed, (5) in order to adjust the tank under the longitudinal and temperate one-for-one clearance, the edges and Angle, adjust the levelness of the mouth, for XiaXian under extremely with the installation. Under the strip and assembly: the next temperate assembly qualified after the next polar zone. Includes 4 blocks under extreme side boards, 2 pieces of side plate and a piece of roof (with manhole). Except for convenient operation and lug one-for-one orientation block in the medial aspect need welding procedure temporary bench plate and assembling good springboard stent. With assembly sequence (under extremely similar) and temperate assembly (1) according to the sphere and typesetting, tube position in the next XiaXian temperate zone plate mouth a mark pole position, seam joint model T, and then lifting 1 block plate, (2) in three block hoisting follow-up with side plate, and a tendency to prevent hull plate, plate every 1 block boundary plate is using welding in equatorial belt The lifting lugs and guide chain adjustment, until the four blocks closed; outside plate (3) under the lifting of the two pieces of extremely, extremely outside edge with adjacent, lifting edges plate can be directly lock readier groups of three sections of weld longmen fixture and hang put inside drag rope. Because the plates with manhole of roof lifting, not under extremely extremely 2 pieces of edge can be based on circular bottom quenched choice 2 ~ 3 fulcrum to support, (4) to ensure the spherical tank welding of ventilation and equipment, and convenient with the very roof manhole in three belt and the sphere.After welding seam all extremely are lifting. At this time of economic considerations, dismantled scaffold, available on the inside surface, support for a rope and set hand chain (generally four guide symmetrically arranged under extremely roof), will be promoted step by step. In the temperate zone assembly: assembly will be set up before the original scaffolding, temperate in girth supreme based on circular anchor rope from fixed in the temperate shell plate welding good lug. Besides a tube scaffold outside the tank, longitudinal seam group housed in the diffculties should not only temporary (for steel scaffolding conditions). The assembly sequence and temperate temperate assembly under similar. In the assembly: with the assembly and the plate with a similar to ensure assembly operation is convenient and safe in the temperate wind mouth welding procedure and binding guardrail, and in good springboard extremely shell plate Settings prevent slippery. Before installation, considering three belt has assembled all the scaffold, cranes and choose larger models (actual construction under three and a group，When installed on the use of 50 tons cranes, cranes, to bring a 100 tons)。 2中文翻譯 球罐基礎(chǔ)的交接驗(yàn)收球罐基礎(chǔ)交工驗(yàn)收前,土建單位必須自檢合格并如實(shí)填寫竣工資料, 基礎(chǔ)強(qiáng)度必須有專業(yè)試驗(yàn)室檢驗(yàn)報(bào)告。一般規(guī)定, 球罐安裝前基礎(chǔ)強(qiáng)度應(yīng)達(dá)到設(shè)計(jì)強(qiáng)度值75 %以上。土建單位申請(qǐng)報(bào)驗(yàn)后,一般由業(yè)主聯(lián)系監(jiān)理、監(jiān)檢、安裝各方聯(lián)合進(jìn)行實(shí)地測(cè)量,按照標(biāo)準(zhǔn)要求對(duì)基礎(chǔ)標(biāo)高, 地腳螺栓預(yù)留孔方位、基礎(chǔ)中心圓偏差等進(jìn)行復(fù)驗(yàn), 如確認(rèn)各項(xiàng)合格,則當(dāng)場(chǎng)簽字接收。 球殼板及零部件的接收復(fù)驗(yàn)：(1) 球殼板及零部件運(yùn)至現(xiàn)場(chǎng)并經(jīng)進(jìn)口貨物商檢合格后,交與施工單位進(jìn)行復(fù)檢。(2) 球殼板檢測(cè)。施工單位按圖紙并參照相關(guān)標(biāo)準(zhǔn),對(duì)球殼板逐張檢查表面質(zhì)量及測(cè)量弧長(zhǎng)和曲率。檢查后發(fā)現(xiàn)北郊2 臺(tái)球罐表面質(zhì)量合格,而小屯儲(chǔ)配廠4 臺(tái)球殼板表面有劃痕、銹蝕及曲率、尺寸超差等情況,。CMP 公司對(duì)此測(cè)量結(jié)果認(rèn)可, 除接受相應(yīng)罰款外,提出現(xiàn)場(chǎng)修復(fù)方案并承諾修復(fù), 待修復(fù)完畢, 由施工單位作MT、VT 檢測(cè), 最后經(jīng)特檢中心驗(yàn)收合格。(3) 球殼板測(cè)厚。施工單位逐臺(tái)抽檢20 % , 結(jié)果S14 球罐赤道帶20 號(hào)板板頭300mm 處板厚大于42mm,法方CMP 公司主動(dòng)提出換板, 使S14 球罐工期推遲3 個(gè)月。(4) 球殼板超聲檢測(cè)。按GB50094 標(biāo)準(zhǔn),施工單位逐臺(tái)對(duì)球殼板作了100 %的全板面和板周邊的超聲檢測(cè),結(jié)果均合格。 支柱安裝：球罐的支柱分上下兩段,上段支柱已焊在赤道板上,現(xiàn)場(chǎng)的安裝是下段支柱先吊裝到球罐基礎(chǔ)上,然后利用外腳手架將上下兩段連接在一起。下段支柱吊裝之前應(yīng)測(cè)量球罐基礎(chǔ)標(biāo)高,在各個(gè)基礎(chǔ)上放樣作出支柱底板圓及放樣圓圖, 然后用斜墊鐵組找平各相鄰基礎(chǔ)。吊裝時(shí), 調(diào)整各支柱的垂直度(這是組對(duì)赤道帶順利與否的保證,現(xiàn)場(chǎng)實(shí)測(cè)垂直度偏差值小于15mm,符合GB12337 和GB50094要求) 。14 根支柱全部安裝完畢后, 應(yīng)及時(shí)搭設(shè)外腳手架以保證后續(xù)赤道帶的吊裝。 球殼板的定位塊焊接及擺放就位：(1) 定位塊焊接。球殼板檢驗(yàn)合格后按編號(hào)擺放,并按所處各帶位置準(zhǔn)備焊接組裝定位塊、吊耳(焊定位塊、吊耳等必須按經(jīng)工藝評(píng)定合格的規(guī)范施焊) 等,因主體采用罐外組裝法、赤道帶、上極帶采用定位塊、吊耳等都在外側(cè), 下溫帶、下極帶所用定位塊、吊耳等焊在板內(nèi)側(cè)。球殼板擺放就位。利用吊車“甩板”將下溫帶、下極帶板按吊裝順序擺放在距球罐基礎(chǔ)內(nèi)側(cè)周圍,上溫帶、赤道帶、上極帶擺放在距球罐基礎(chǔ)外側(cè)周圍(注意留出吊車通道) 。 赤道帶的組裝：赤道帶的組裝是整臺(tái)球罐組裝的基準(zhǔn),其組裝建立在上下段支柱安裝就位的前提下, 所以必須調(diào)整好支柱垂直度。(1) 帶支柱的赤道板安裝。按照吊裝順序,預(yù)先在上下兩段支柱對(duì)口處劃中心線, 按對(duì)中線在兩段支柱接頭處各焊定位螺栓孔板3 個(gè), 在帶支柱的赤道板上焊接掛鋼絲繩的吊耳。第一塊帶支柱的赤道板吊起后,利用拖拉繩及外腳手架將上下兩段支柱按對(duì)中線對(duì)中,鎖緊螺栓,同時(shí)拉好內(nèi)外兩根鋼絲纜風(fēng)繩,固定后再進(jìn)行水平垂直方位的調(diào)整;(2) 繼續(xù)吊裝第二塊帶支柱的赤道板,同時(shí)安裝好兩相鄰支柱間的拉桿;(3) 吊裝第一塊不帶支柱的赤道板, 插入第一、二塊柱腿板之間, 利用龍門卡具調(diào)整好間隙(5 ±2mm) ,注意曲率控制;(4) 利用上述方法,依此類推,吊裝一塊帶支柱的赤道板后,在其間插入一塊不帶支柱的赤道板,直至整圈赤道帶閉合。組裝時(shí)利用柱腿拉桿和卡具依次調(diào)整好赤道帶橢圓度上下弦水平度、間隙、錯(cuò)邊量、棱角度。 下溫帶的組裝：赤道帶的組裝合格后進(jìn)行下溫帶的組裝。需要注意的是,赤道帶與上、下溫帶間環(huán)縫的T型縫位置應(yīng)嚴(yán)格監(jiān)控,組焊下溫帶與赤道帶間的環(huán)縫所用定位塊、吊耳等焊在板外側(cè), 而下溫帶縱縫所用定位塊、吊耳等焊在板內(nèi)側(cè)。除環(huán)縫外腳手架外,還需在板內(nèi)側(cè)搭設(shè)臨時(shí)板凳支架。 下溫帶組裝順序:(1) 根據(jù)球罐排版圖,在赤道帶下弦口板面上依次劃出下溫帶位置,標(biāo)出的T 型縫接頭,然后吊裝已擺放在球罐中心圓內(nèi)的第一塊下溫帶球殼板;(2) 將吊裝的第一塊下溫帶球殼板與赤道帶間用龍門卡具鎖緊, 然后拉住焊在下溫帶與赤道帶殼板上的吊耳,用導(dǎo)鏈調(diào)節(jié)殼板的圓弧度,使其棱角符合要求;(3) 吊裝第二塊下溫帶球殼板,用龍門卡具從罐外側(cè)鎖緊環(huán)向?qū)? 從罐內(nèi)側(cè)鎖緊縱向?qū)?。注意測(cè)量殼板的圓弧度及棱角度;(4) 依次吊裝后續(xù)的下溫帶球殼板。為防止殼板下墜,每隔三塊板即利用焊在赤道帶板上的吊耳拉住殼板并用導(dǎo)鏈調(diào)節(jié),直至整圈下溫帶閉合;(5) 依次調(diào)整好下溫帶縱、環(huán)縫的對(duì)口間隙、錯(cuò)邊量及棱角度,調(diào)整好下弦口的水平度,為下極帶的安裝打好基礎(chǔ)。 下極帶的組裝：赤道帶及下溫帶的組裝合格后進(jìn)行下極帶的組裝。下極帶包括4 塊邊板、2 塊中邊板和1 塊頂板(帶人孔) 。為操作方便除對(duì)口定位塊、吊耳等外還需在板內(nèi)側(cè)焊接搭設(shè)臨時(shí)板凳支架并綁扎好跳板。下極帶組裝順序(與下溫帶組裝類似) :(1) 根據(jù)球罐排版圖及管口方位圖,在下溫帶下弦口依次劃出極帶板位置,標(biāo)出T 型縫接頭,然后吊裝第1 塊下極板;(2) 依次吊裝后續(xù)3 塊下極帶邊板,同時(shí)為防止殼板下墜趨勢(shì),每隔1 塊邊板即利用焊在赤道帶板 上的吊耳并用導(dǎo)鏈調(diào)節(jié),直至4 塊外邊板整圈閉合;(3) 吊裝下極2 塊極中邊板,由于與外邊板三邊相鄰,吊裝組對(duì)時(shí)可直接鎖緊三段焊縫間的龍門卡具而不須掛設(shè)內(nèi)部拖拉繩。因帶人孔的板中頂板暫不吊裝,下極2 塊極中邊板可在球罐基礎(chǔ)圓底部選擇2～3 個(gè)支點(diǎn)進(jìn)行支撐;(4) 為保證球罐焊接時(shí)的罐內(nèi)通風(fēng)及機(jī)具設(shè)備進(jìn)出方便,帶人孔的下極頂板可在球罐三大帶和上極焊縫全部焊完后進(jìn)行吊裝。此時(shí)出于經(jīng)濟(jì)方面的考慮,在拆除內(nèi)部腳手架后, 可利用上極作支撐面,掛設(shè)鋼絲繩、手拉導(dǎo)鏈(一般四組對(duì)稱布置) ,將下極頂板逐步提升到位。 上溫帶的組裝：組裝前將原有腳手架往上搭設(shè)至上溫帶環(huán)縫處,在基礎(chǔ)圓外地面上固定好錨繩,在上溫帶殼板上焊好吊耳。除環(huán)縫處有鋼管腳手架外, 縱縫組對(duì)時(shí)應(yīng)在外側(cè)搭設(shè)臨時(shí)爬梯(因不具備鋼管腳手架條件) 。上溫帶組裝順序與下溫帶的組裝類似。 上極帶的組裝：上極板的組裝與下極帶組裝類似,為保證操作方便及安全,需在上溫帶上弦口處焊接支架并搭設(shè)護(hù)欄,綁扎好跳板, 同時(shí)在上極殼板上設(shè)置防滑條。吊裝前,考慮到三大帶已全部組裝完成及外腳手架,吊車選用更大的型號(hào)(實(shí)際施工中三大帶及下極組裝時(shí)使用50 噸吊車,上極帶使用100 噸吊車)
