沁陽盆式沁陽橡膠支座下面應(ying)設置(zhi)支承墊(dian)(dian)石(shi)(shi)(shi)(shi)，支承墊(dian)(dian)石(shi)(shi)(shi)(shi)混(hun)(hun)凝土強度(du)(du)等(deng)級不宜低于C40.墊(dian)(dian)石(shi)(shi)(shi)(shi)高度(du)(du)應(ying)考慮 支座裝置(zhi)、維護和(he)(he)(he)替換的(de)方便(bian)。支承墊(dian)(dian)石(shi)(shi)(shi)(shi)及墩(dun)(dun)頂混(hun)(hun)凝土應(ying)該按JTG D62-2004的(de)局部承壓部件要求裝備(bei)相應(ying)的(de)鋼筋網。墩(dun)(dun)臺頂面需按錨固(gu)套筒(tong)規格、數量預(yu)留栓孔。預(yu)留栓孔的(de)直(zhi)徑和(he)(he)(he)深度(du)(du)大于套筒(tong)直(zhi)徑和(he)(he)(he)長度(du)(du)50mm~60mm,中(zhong)心誤(wu)差不該超過10mm。

　　沁陽盆式沁陽橡膠支座運輸(shu)到現場后(hou)，應(ying)該開箱檢(jian)查支座各部分零件(jian)及裝(zhuang)箱單(dan)，檢(jian)查合格后(hou)再(zai)(zai)放(fang)入(ru)包(bao)裝(zhuang)箱，裝(zhuang)置(zhi)時(shi)再(zai)(zai)開箱。活動支座在(zai)開箱后(hou)應(ying)該留(liu)意對聚(ju)四氟(fu)乙烯板(ban)(ban)和(he)不銹(xiu)鋼(gang)(gang)冷軋(ya)鋼(gang)(gang)板(ban)(ban)的(de)保護，避免劃傷或(huo)許有贓物附著(zhu)在(zai)乙烯板(ban)(ban)和(he)冷軋(ya)鋼(gang)(gang)板(ban)(ban)的(de)表(biao)面，而且檢(jian)查5201-2硅脂是否注(zhu)滿。

　　盆式沁陽橡膠支座裝置時，支承(cheng)墊(dian)(dian)(dian)石頂面(mian)應該鑿(zao)毛，并用清水沖去墊(dian)(dian)(dian)石上面(mian)的雜物，待墊(dian)(dian)(dian)石表面(mian)枯(ku)燥后(hou)，在錨固螺栓(shuan)孔位置以外的支承(cheng)墊(dian)(dian)(dian)石頂面(mian)涂滿環氧砂漿調(diao)平層，支座就(jiu)位后(hou)、對中并調(diao)整水平后(hou)，用墊(dian)(dian)(dian)塊將(jiang)支座墊(dian)(dian)(dian)起。

　　用環氧砂漿(jiang)或(huo)強度等級(ji)較(jiao)高的砂漿(jiang)灌注套筒周圍空(kong)隙及支座底(di)板四(si)周未填(tian)滿環氧砂漿(jiang)的位置(zhi)，而且將砂漿(jiang)搗實，完工(gong)后應該(gai)將支座底(di)板以外溢(yi)出的砂漿(jiang)清理干凈，砂漿(jiang)硬化后再拆(chai)去支座墊塊。
