20、............................................................................................................232測(cè)量放線定位→基坑挖土至標(biāo)高6.00米→換土，填土至標(biāo)高4.50米→消防水池底板施工→消防水池外壁施工→消防水池頂板施工→土方回填。2、基坑土方開(kāi)挖外運(yùn)（1）根據(jù)概算書(shū)，場(chǎng)地土總挖方量約2730.345立方米。由于基坑

21、開(kāi)挖土方量不大，采用從西往東開(kāi)挖。（2）基坑邊坡采用50%自然放坡。（3）土方開(kāi)挖采用挖掘機(jī)開(kāi)挖的方式，并配合人工清挖邊坡面?，F(xiàn)場(chǎng)擬配備2臺(tái)反鏟挖掘機(jī)開(kāi)挖；另用4臺(tái)十五噸自卸汽車(chē)外運(yùn)，每天挖運(yùn)土方計(jì)算式為：每臺(tái)自卸車(chē)運(yùn)土量每小時(shí)裝運(yùn)車(chē)輛臺(tái)數(shù)每天作業(yè)時(shí)間（小時(shí)）10.0m3臺(tái)車(chē)4臺(tái)次小時(shí)12小時(shí)（早上7時(shí)～晚上7時(shí)）=480.0m3在3天內(nèi)可開(kāi)挖完成。1.61.6施工準(zhǔn)備工作施工準(zhǔn)備工作1、測(cè)量人員做好技術(shù)準(zhǔn)備提前定好外圍控制線并隨時(shí)跟蹤

22、挖土標(biāo)高，加強(qiáng)標(biāo)高控制嚴(yán)禁超挖.2、技術(shù)部門(mén)應(yīng)對(duì)現(xiàn)場(chǎng)施士人員做出明確交底畫(huà)出集水坑等位置局部詳圖確保位置準(zhǔn)確。3、施工前土方組長(zhǎng)向所有參加施工的人員進(jìn)行有針對(duì)性的技術(shù)交底必須使每個(gè)操作者對(duì)施工中的技術(shù)要求心中有數(shù)。4、了解施工機(jī)械設(shè)備的技術(shù)參數(shù)與性能。5、做好施工場(chǎng)地的通平工作。6、按照施工圖及建設(shè)單位提供的控制軸線準(zhǔn)確測(cè)出水池外圍線并將水池周邊控制軸線引測(cè)到場(chǎng)地周邊適當(dāng)部位妥善保護(hù)。7、根據(jù)現(xiàn)場(chǎng)平面布置接通場(chǎng)地施工、生活用電、用水:鋼
