道路護欄施工總體方案

    道(dao)路護欄工(gong)(gong)(gong)程(cheng)擬選用要點突破關健工(gong)(gong)(gong)序、平行(xing)作業(ye)(ye)法施工(gong)(gong)(gong)，排水管道(dao)、道(dao)路護欄施工(gong)(gong)(gong)為本工(gong)(gong)(gong)程(cheng)的關健工(gong)(gong)(gong)序，其他各項作業(ye)(ye)都必(bi)須先確保(bao)(bao)這二項作業(ye)(ye)的順利進行(xing)。全體施工(gong)(gong)(gong)中合理進行(xing)流水施工(gong)(gong)(gong)，施工(gong)(gong)(gong)各階段勞動(dong)力組織相對(dui)均衡，各班組分工(gong)(gong)(gong)清晰，搭接(jie)嚴密(mi)，在確保(bao)(bao)質量和工(gong)(gong)(gong)期的前(qian)提下，做(zuo)到本錢的最優(you)化。

    把握先(xian)地下(xia)后(hou)地上、先(xian)深后(hou)淺的(de)施(shi)(shi)(shi)工準則(ze)。道(dao)路(lu)護欄施(shi)(shi)(shi)工次序如下(xia)：土方開挖(wa)施(shi)(shi)(shi)工→排水管道(dao)的(de)施(shi)(shi)(shi)工→路(lu)基(ji)施(shi)(shi)(shi)工→級配碎(sui)石(shi)(shi)底底層施(shi)(shi)(shi)工→水泥(ni)安(an)穩石(shi)(shi)屑層施(shi)(shi)(shi)工→水泥(ni)混凝土路(lu)面(mian)施(shi)(shi)(shi)工→美化、照明、交(jiao)通設(she)施(shi)(shi)(shi)施(shi)(shi)(shi)工。

    首要施(shi)工項目的(de)施(shi)工計劃、道路工程：道路護欄基(ji)底處理選用推土機、挖掘機鏟除(chu)施(shi)工規模的(de)草(cao)皮、表土和樹(shu)木、樹(shu)根。特(te)別是回(hui)填土、腐(fu)植土要用挖掘機悉數鏟除(chu)，以確保基(ji)底土的(de)密實。

    道路(lu)護(hu)欄路(lu)基挖(wa)方(fang)(fang)施工計劃路(lu)基開挖(wa)選用分段縱挖(wa)法(fa)為主(zhu)，分層縱挖(wa)法(fa)為輔的辦(ban)法(fa)施工，挖(wa)掘(jue)機挖(wa)裝，自卸轎(jiao)車運送(song)。本(ben)合同段可(ke)使用土(tu)方(fang)(fang)選用推(tui)土(tu)機作業，遠運使用土(tu)方(fang)(fang)挖(wa)掘(jue)機挖(wa)裝，自卸轎(jiao)車運送(song)的辦(ban)法(fa)作業。

    道路(lu)護欄路(lu)基填(tian)方施工(gong)計(ji)劃路(lu)基填(tian)方選用分(fen)區分(fen)段填(tian)筑，挖掘機或裝(zhuang)載機裝(zhuang)料(liao)(liao)，自(zi)卸(xie)轎車(che)運料(liao)(liao)、推土(tu)機攤(tan)鋪、平地機整(zheng)平、推進壓(ya)路(lu)機碾壓(ya)、核(he)子密度(du)儀法(fa)檢(jian)測密實度(du)。道路(lu)護欄級配碎(sui)石底底層施工(gong)計(ji)劃選用安(an)穩土(tu)拌(ban)合站拌(ban)合，自(zi)卸(xie)轎車(che)運送(song)，平地機整(zheng)平、15T壓(ya)路(lu)機初(chu)壓(ya)、振蕩(dang)壓(ya)路(lu)機壓(ya)實。
