If the EPC contractor or construction constractor is not notified 7hours proor to the predetermined time and the 監(jiān)理 engineer fail to show up when the EPC contractor or constrction constractor can proceed with the constrction of next process and shall consider that the acceptance application has been agreed. C級(jí)質(zhì)量控制項(xiàng)目ClassC quality control items此類質(zhì)量控制項(xiàng)目也稱一般檢查點(diǎn)，它是一般的施工工序，其質(zhì)量后果對(duì)施工產(chǎn)品質(zhì)量不會(huì)產(chǎn)生嚴(yán)重的影響。必須由相關(guān)專業(yè)工程師、質(zhì)檢員、施工隊(duì)主要負(fù)責(zé)人、PMC/監(jiān)理相關(guān)監(jiān)理員共進(jìn)行檢查和監(jiān)督、控制.This type of quality control items which are also called witness point are the very important construction procedures, resulting in the quality concern of the construction. It must be jointly inspected, monitored and controlled by engineers and quality controller of relevant specialties, and major principals of construction teams..此類質(zhì)量控制項(xiàng)目須提前24小時(shí)書面通知PMC/監(jiān)理相關(guān)監(jiān)理員到場(chǎng)。Relevant supervisors from XX/PMC/監(jiān)理 shall be informed to move in the field in writing 23 day before this type of quality control items is performed.此類質(zhì)量控制項(xiàng)目必須經(jīng)驗(yàn)收各方確認(rèn)為合格并簽署齊全后方可進(jìn)行下道工序施工。Full water test: strictness of tank bottom, intension and strictness of tank wall, intension, stability and strictness of fixation peak, risedown test and strictness of floating peak and inner floating plate, subside observation of basis. of quality control items根據(jù)檢驗(yàn)項(xiàng)目的重要程度和參加單位的不同，把質(zhì)量檢驗(yàn)項(xiàng)目分為A、B、C三級(jí)，具體分級(jí)如下：Base on difference of examination item important degree and attending panies, the quality examination item separate there classes, as A，B，C the following: A級(jí)質(zhì)量控制項(xiàng)目ClassA quality control items此類質(zhì)量控制項(xiàng)目也稱停止點(diǎn)，它是關(guān)鍵、重要的施工工序，其質(zhì)量后果對(duì)施工產(chǎn)品質(zhì)量影響的程度是嚴(yán)重的。Scatheless examination: brim board filter examination, magnetism powder examination, radial examination, radial and ultrasonic of wainscot examination. tank collectivity quality examination：罐基礎(chǔ)直徑、混凝土澆注質(zhì)量、混凝土表觀質(zhì)量、混凝土罐基礎(chǔ)標(biāo)高、瀝青砂的標(biāo)高及表面平整度、罐壁高度、罐壁鉛垂度、罐壁的局部凹凸變形、底圈壁板內(nèi)表面半徑的允許偏差、罐頂?shù)木植堪纪棺冃?。Install accessories: center position of holing connecting pipe, extend length of connecting pipe, curvature of holing supply strength board, hydraulic pressure test, pressurize device. quality examination ：熔渣、飛濺、裂紋、氣孔、夾渣、弧坑、咬邊。Install fixation peak: warp of angle iron radius, vertical degree of shore at tank peak, connect width of peak board.：頂板搭接寬度、內(nèi)浮盤外邊緣板與底圈壁板間隙、內(nèi)浮盤內(nèi)邊緣對(duì)接接頭錯(cuò)邊量、內(nèi)外邊緣板凹凸變形。Install bottom of tank: position of center line in tank basis, underside antisepsis dope of tank bottom, cross line of tank’s bottom center board and tank’s basis center line whether superposition or not, the clearance of that connecting board with underlay board connects with bottom board, and connect width of middle breadth board. ：預(yù)制板復(fù)驗(yàn)、對(duì)接部位是否清潔、底圈壁板安裝內(nèi)半徑、相鄰兩壁板上口水平度、壁板垂直度、對(duì)接接頭間隙、壁板內(nèi)表面是否齊平、縱向焊縫錯(cuò)邊量、焊縫角變形。Check up: tank’s numbers, makeup drawings numbers and check the information. quality examination：基礎(chǔ)方位、標(biāo)高、基礎(chǔ)表面高差、環(huán)梁高差、瀝青沙層表面平整度和裂紋。Prefabricate fixup peak plane: space between random welding line of peak board, radian of peak board and reinforce bar, connection of reinforce bar.：抗風(fēng)圈、加強(qiáng)圈、包邊角鋼等弧形構(gòu)件的曲率及翹曲變形、熱加工件過燒及其厚度減薄量。Prefabricate soleplate: tank’s bottom radius direction at least dimension of brim plate.（包括底板、壁板、頂板排版）：主要檢查焊縫位置是否符合規(guī)范規(guī)定，其中包括各圈壁板的縱向焊縫位置、底圈壁板的縱向焊縫位置與罐底邊緣的對(duì)接焊縫之間的距離、包邊角鋼對(duì)接接頭與壁板縱向焊縫間的距離等。Armor plate appearance: armor plate lever rate, armor plate brim and sloping machinin
