盆式橡膠支座下面(mian)應(ying)設置(zhi)支承(cheng)(cheng)墊(dian)(dian)(dian)石(shi)，支承(cheng)(cheng)墊(dian)(dian)(dian)石(shi)混凝(ning)土(tu)強度等級(ji)不(bu)宜低于C40.墊(dian)(dian)(dian)石(shi)高(gao)度應(ying)考慮 支座裝置(zhi)、維護和替換(huan)的(de)方(fang)便。支承(cheng)(cheng)墊(dian)(dian)(dian)石(shi)及墩頂(ding)混凝(ning)土(tu)應(ying)該按(an)JTG D62-2004的(de)局部(bu)承(cheng)(cheng)壓(ya)部(bu)件要(yao)求裝備相應(ying)的(de)鋼筋網。墩臺(tai)頂(ding)面(mian)需按(an)錨固套筒(tong)規格、數量(liang)預留栓孔。預留栓孔的(de)直徑和深度大于套筒(tong)直徑和長度50mm~60mm,中心誤差不(bu)該超過10mm。

　　盆式橡膠支座運輸到(dao)現(xian)場后(hou)(hou)，應該(gai)開(kai)(kai)箱(xiang)(xiang)檢(jian)查(cha)支座各部分零件(jian)及裝箱(xiang)(xiang)單，檢(jian)查(cha)合(he)格后(hou)(hou)再放入包(bao)裝箱(xiang)(xiang)，裝置(zhi)時再開(kai)(kai)箱(xiang)(xiang)。活(huo)動支座在開(kai)(kai)箱(xiang)(xiang)后(hou)(hou)應該(gai)留意對聚四氟乙烯板(ban)和不(bu)銹(xiu)鋼冷軋鋼板(ban)的保護，避免(mian)劃傷或許(xu)有贓物附著在乙烯板(ban)和冷軋鋼板(ban)的表(biao)面，而且檢(jian)查(cha)5201-2硅脂是(shi)否注滿。

　　盆式橡膠支座裝置時(shi)，支(zhi)(zhi)承墊(dian)(dian)石(shi)(shi)頂面(mian)(mian)(mian)應該鑿毛，并用(yong)清水沖去墊(dian)(dian)石(shi)(shi)上面(mian)(mian)(mian)的雜物，待墊(dian)(dian)石(shi)(shi)表面(mian)(mian)(mian)枯燥后，在錨固(gu)螺栓孔位(wei)置以外的支(zhi)(zhi)承墊(dian)(dian)石(shi)(shi)頂面(mian)(mian)(mian)涂(tu)滿環氧砂漿調(diao)平層(ceng)，支(zhi)(zhi)座就位(wei)后、對(dui)中并調(diao)整(zheng)水平后，用(yong)墊(dian)(dian)塊將支(zhi)(zhi)座墊(dian)(dian)起。

　　用(yong)環氧砂漿(jiang)或強(qiang)度等級較高的砂漿(jiang)灌注套筒(tong)周(zhou)圍空隙及支(zhi)(zhi)座底板四周(zhou)未填滿環氧砂漿(jiang)的位置，而且將(jiang)砂漿(jiang)搗實，完(wan)工(gong)后(hou)應該將(jiang)支(zhi)(zhi)座底板以(yi)外溢出的砂漿(jiang)清理干(gan)凈，砂漿(jiang)硬化后(hou)再拆去支(zhi)(zhi)座墊塊。
