安平縣道路護欄施工總體方案

    道路(lu)護(hu)欄(lan)工(gong)(gong)(gong)程擬選用要點突破關健(jian)工(gong)(gong)(gong)序(xu)、平行作業法施(shi)工(gong)(gong)(gong)，排(pai)水(shui)(shui)管道、道路(lu)護(hu)欄(lan)施(shi)工(gong)(gong)(gong)為本(ben)工(gong)(gong)(gong)程的關健(jian)工(gong)(gong)(gong)序(xu)，其他各項作業都必(bi)須先確保(bao)這(zhe)二(er)項作業的順利進行。全(quan)體施(shi)工(gong)(gong)(gong)中合理進行流水(shui)(shui)施(shi)工(gong)(gong)(gong)，施(shi)工(gong)(gong)(gong)各階段勞動力組(zu)織(zhi)相(xiang)對均(jun)衡，各班(ban)組(zu)分(fen)工(gong)(gong)(gong)清(qing)晰，搭接嚴密，在確保(bao)質量和工(gong)(gong)(gong)期的前提下，做到本(ben)錢(qian)的最優化。

    把握先(xian)地下(xia)后地上、先(xian)深后淺的施(shi)工準則。道(dao)路護(hu)欄施(shi)工次(ci)序如下(xia)：土(tu)方開(kai)挖施(shi)工→排水管道(dao)的施(shi)工→路基(ji)施(shi)工→級配碎石底底層施(shi)工→水泥安穩石屑層施(shi)工→水泥混凝土(tu)路面施(shi)工→美(mei)化、照明(ming)、交通(tong)設施(shi)施(shi)工。

    首(shou)要(yao)施(shi)工(gong)(gong)項目的(de)施(shi)工(gong)(gong)計劃、道(dao)路工(gong)(gong)程：道(dao)路護欄基底處(chu)理選用推(tui)土(tu)(tu)機、挖(wa)掘(jue)機鏟(chan)除施(shi)工(gong)(gong)規(gui)模(mo)的(de)草皮、表土(tu)(tu)和樹木、樹根。特別是回填土(tu)(tu)、腐植土(tu)(tu)要(yao)用挖(wa)掘(jue)機悉(xi)數鏟(chan)除，以確保(bao)基底土(tu)(tu)的(de)密實。

    道路(lu)護欄路(lu)基挖(wa)方(fang)(fang)(fang)施(shi)工(gong)計劃(hua)路(lu)基開挖(wa)選用(yong)分段(duan)縱挖(wa)法(fa)(fa)(fa)為主(zhu)，分層縱挖(wa)法(fa)(fa)(fa)為輔的辦法(fa)(fa)(fa)施(shi)工(gong)，挖(wa)掘機挖(wa)裝(zhuang)，自卸(xie)轎車運(yun)送。本合(he)同段(duan)可使用(yong)土方(fang)(fang)(fang)選用(yong)推土機作業(ye)(ye)，遠運(yun)使用(yong)土方(fang)(fang)(fang)挖(wa)掘機挖(wa)裝(zhuang)，自卸(xie)轎車運(yun)送的辦法(fa)(fa)(fa)作業(ye)(ye)。

    道路(lu)(lu)護欄路(lu)(lu)基填(tian)方(fang)施工計(ji)劃(hua)路(lu)(lu)基填(tian)方(fang)選用(yong)分(fen)區分(fen)段填(tian)筑，挖掘機(ji)(ji)(ji)或裝載機(ji)(ji)(ji)裝料，自(zi)卸轎車運料、推土機(ji)(ji)(ji)攤鋪(pu)、平地(di)機(ji)(ji)(ji)整(zheng)平、推進(jin)壓路(lu)(lu)機(ji)(ji)(ji)碾(nian)壓、核子密(mi)度儀法檢測密(mi)實度。道路(lu)(lu)護欄級配碎石底底層(ceng)施工計(ji)劃(hua)選用(yong)安穩土拌(ban)合(he)站拌(ban)合(he)，自(zi)卸轎車運送，平地(di)機(ji)(ji)(ji)整(zheng)平、15T壓路(lu)(lu)機(ji)(ji)(ji)初壓、振蕩壓路(lu)(lu)機(ji)(ji)(ji)壓實。
