施工場地基本概況為滿足施工進(jìn)度及運(yùn)輸要求，每一個(gè)庫準(zhǔn)備投入2臺(tái)QTZ6013塔吊，一共8臺(tái)塔吊。以及其他加工設(shè)備（見設(shè)備及功率明細(xì)表）?，F(xiàn)場布置8個(gè)鋼筋加工車間和2個(gè)木工加工車間，每2棟倉庫統(tǒng)一設(shè)置一個(gè)一級(jí)配電柜。三、 電源接駁點(diǎn)概況1 本工程電源接駁點(diǎn)分別位于場地南側(cè)七庫外側(cè)的800KVA的配電房，現(xiàn)場可提供本工程臨時(shí)用電量容量為800KVA。2 本工程按項(xiàng)目總的進(jìn)度計(jì)劃結(jié)合本方案第五章第一條第7點(diǎn)和第14點(diǎn)和17點(diǎn)計(jì)算結(jié)果，到最高峰時(shí)的用電量為497.58KVA，滿足施工需求。3 本工程采用三級(jí)配電，從總配電室到各一級(jí)配電柜，一級(jí)配電柜到各二級(jí)配電箱，各庫二及配電箱至各用電點(diǎn)三級(jí)開關(guān)箱。第三章 施工部署一、 總體目標(biāo)質(zhì)量目標(biāo)：合格，一次驗(yàn)收合格率100%。安全目標(biāo)：堅(jiān)持“安全第一、預(yù)防為主”的工作方針，確保無重大工傷事故，輕傷頻率控制在4以內(nèi)。二、 現(xiàn)場臨時(shí)用電部署：三級(jí)配電二級(jí)保護(hù)現(xiàn)場在變壓器旁設(shè)置總配電室各一級(jí)配電柜各棟分別設(shè)置3個(gè)二級(jí)配電箱各設(shè)備專用插座箱、照明專用箱為三級(jí)箱；本工程分期建設(shè)：一期有1號(hào)、2號(hào)庫區(qū)及配套用房；二期有3號(hào)、4號(hào)、5號(hào)、6號(hào)四棟庫區(qū)及配套用房，本方案為二期施工用電方案。在3號(hào)庫、4號(hào)庫之間設(shè)置1#一級(jí)配電柜、5號(hào)庫、6號(hào)庫之間設(shè)置2#一級(jí)配電柜、辦公區(qū)和生活區(qū)設(shè)置專用3#一級(jí)配電柜。根據(jù)總進(jìn)度計(jì)劃安排，每棟庫房之間開始施工的時(shí)間順序相差十天；一套基礎(chǔ)錘擊樁所使用的設(shè)備需用70KW，按三套設(shè)備同時(shí)施工共有210KW,錘擊樁設(shè)備施工的時(shí)候，其他如鋼筋、模板加工設(shè)備還沒有投入使用，塔吊也沒有完全投入使用，并且三套錘擊樁的負(fù)荷小于基礎(chǔ)主體施工階段用電設(shè)備的負(fù)荷，所以在施工臨時(shí)用電負(fù)荷計(jì)算的時(shí)候，不考慮錘擊設(shè)備的用電負(fù)荷。主體施工階段及裝飾裝修期間用電高峰是塔吊、鋼筋加工、模板加工設(shè)備同時(shí)使用的階段，所以最大負(fù)荷主要考慮各樓層施工機(jī)具、照明、模板加工，塔吊運(yùn)轉(zhuǎn)及鋼筋加工的用電。擬從配電房設(shè)置一個(gè)主線路到總配電室；3號(hào)4號(hào)庫共用1#一級(jí)配電柜，5號(hào)6號(hào)庫共用2#一級(jí)配電柜、辦公區(qū)和生活區(qū)共用3#一級(jí)配電柜；各一級(jí)配電柜分別設(shè)置4條線路至固定二級(jí)配電箱（鋼筋加工場地配電箱和塔吊配電箱）和2條線路至各棟物流庫樓層的移動(dòng)二級(jí)配電箱（樓層用電配電箱）。從二級(jí)箱引出線至三級(jí)箱及專用設(shè)備控制箱，實(shí)現(xiàn)一機(jī)一閘一漏。三、
