21、........................................................................297.3現(xiàn)場(chǎng)文明施工...................................................................................................................30池壁內(nèi)無粘結(jié)預(yù)應(yīng)力筋采用7Φj5鋼絞線，

22、豎向均勻布置64束（37Φj5）預(yù)應(yīng)力筋，環(huán)向共設(shè)置122圈（由呈半圓形的兩束筋組成）預(yù)應(yīng)力筋，且為分段均布（分57Φj5、4Φj5、37Φj5三種規(guī)格），詳見附件二、三。砼等級(jí)：地下無預(yù)應(yīng)力筋部分的結(jié)構(gòu)砼標(biāo)號(hào)為C30、S8，其余為C40、S8，砼中均摻4%TJ外加劑。1.2工程特點(diǎn)工程特點(diǎn)1.2.1池體體形特異，內(nèi)外表面均為弧形，池壁又為變截面，池體內(nèi)空間大，因此構(gòu)筑物的垂直度、同心度、標(biāo)高、壁厚、內(nèi)外半徑等不易控制，施工難度較大。1

23、.2.2池壁與地面不垂直(形成夾角)，給砼澆筑帶來很大的困難。1.2.3模板及其內(nèi)外楞所用鋼管要根據(jù)池體作特殊加工。1.2.4模板和支撐體系結(jié)構(gòu)特殊。1.2.5消化池預(yù)應(yīng)力施工技術(shù)含量高、難度大，且工作量大。1.2.6工期要求緊，比以往同類工程縮短了一半以上。1.3施工條件施工條件1.3.1施工現(xiàn)場(chǎng)由于受到砼灌注樁樁基和基坑開挖施工的影響，加上工期緊，給現(xiàn)場(chǎng)布置帶來很大難度。1.3.2施工場(chǎng)地狹小，工地地處錢塘江邊，受臺(tái)風(fēng)的影響比較大。
