3#水塔環(huán)基施工方案.doc

1. 工程概況
托克托電廠二期工程#3冷卻塔位于主廠房北側(cè)，為雙曲線型自然通風(fēng)冷卻塔。中心坐標(biāo)：A=5953.60；B=2807.30，±0.000m相當(dāng)于絕對(duì)標(biāo)高：1065.500m，淋水面積6500m2，塔高125m，進(jìn)風(fēng)口高度8.0m，通風(fēng)筒為現(xiàn)澆鋼筋砼結(jié)構(gòu)，殼體最大半徑46.820m，喉部半徑26.280m，最大厚度750mm，最小厚度180mm，在8.870m和11.680m標(biāo)高處設(shè)置兩層環(huán)形牛腿，塔頂設(shè)一剛性環(huán)。
環(huán)形基礎(chǔ)結(jié)構(gòu)形式為超長(zhǎng)環(huán)板型大體積鋼筋砼結(jié)構(gòu)。環(huán)基寬5.0m，高2.0m，中心半徑：50.712m。為控制溫度裂縫，環(huán)基內(nèi)
