11、A07、A08、A11、A12，3#塔吊處于高程處于15.16~24.56之間，該高程范圍內(nèi)土質(zhì)為2強(qiáng)風(fēng)化粗?；◢弾r?！?12強(qiáng)風(fēng)化粗粒花崗巖：褐黃、灰褐色，巖石風(fēng)化強(qiáng)烈，組織結(jié)構(gòu)已部分○11破壞，遇水崩解。上部呈土柱狀，下部多呈砂土狀，底部不均勻含有少量強(qiáng)風(fēng)化巖塊，巖塊手可折斷。巖體極破碎，為極軟巖～軟巖，巖體基本質(zhì)量等級為Ⅴ級。該層見于所有鉆孔。揭露層厚2.30～17.20m，平均層厚7.91m；層頂埋深19.20～33.70m，層

12、頂高程28.86～14.03m。加“937043552”獲取CAD圖紙。三.塔吊選型及主要技術(shù)參數(shù)塔吊選型及主要技術(shù)參數(shù)本工程裙樓施工階段除一層部分鋼梁（4根）重達(dá)約20t重外，其余均在單根4.9t以內(nèi)，超重的鋼梁擬分4段吊裝，塔吊覆蓋區(qū)的鋼梁最小起重量可控制在4.9t以內(nèi)。故本工程3#塔吊擬采用JCD260動臂塔，臂長為50m，安裝高度最大約55m，采用一道附墻。加“937043552”獲取CAD圖紙。JCD260塔吊工作性能四.塔吊
