38、計圖紙集中下料、分型號、規(guī)格堆碼、編號，平板車運到現(xiàn)場，在橋墩鋼筋骨架定位模具上綁扎。墩柱鋼筋與樁基或上節(jié)墩柱預埋鋼筋焊接，接長時采用單面焊，焊縫長度不小于10d，焊接人員必須全部持證上崗，以保證焊接質(zhì)量。接長鋼筋時，為保證鋼筋不變形，可在墩頂搭設(shè)鋼管井架輔助施工。在綁扎完鋼筋后，用3根纜風繩將鋼筋固定，防止鋼筋整體傾覆。結(jié)構(gòu)主筋接頭采用直筒螺紋或焊接方式連接，主筋與箍筋之間采用扎絲進行綁扎。綁扎或焊接的鋼筋網(wǎng)和鋼筋骨架不得有變形、松脫現(xiàn)象。采用同標號砂漿混凝土墊塊。（2）模板工程1）模板型式矩形實心橋墩模板均采用1.2m*1.5m鋼模板，矩形墩外模由兩片主模和兩片側(cè)模組成，主模面板尺寸1.5

39、米(高)×1.2m(寬)，側(cè)模面板尺寸1.5m(高)×1.2m(寬)，外模共4塊模板。用汽車吊和運輸車輛將大模板運至施工現(xiàn)場，將實心墩周邊場地清理完成后，現(xiàn)場用汽車吊進行拼裝；先立一側(cè)主模，再立兩邊側(cè)模，最后立另一側(cè)主模，調(diào)整好模板位置后，用螺栓和模板連接件將主模和側(cè)模連接牢固，并及時安裝好對拉螺栓。然后用水準儀控制第一套模板上口標高，用薄鐵片將模板調(diào)平，以保證上部其他模板上口水平模板組成平面圖如上；模板組成立面圖如下圖：2）砼澆筑墩身砼澆筑采用混凝土運輸罐車運輸，泵送入模，柱墩高度在4m或4m以下，均一次性澆筑，柱墩高度在4m以上，分層澆筑，漏斗置于墩頂中心，人工進入到墩
