在S223萬載后槎-袁州金瑞(株金線)二級公路改建工程金瑞路段施工現場，水泥路面破碎機和壓路機正在(zai)施工作(zuo)業，與以往用大量的(de)用破(po)碎鎬破(po)碎水泥(ni)路面不同(tong)的(de)是，在(zai)破(po)碎原水泥(ni)路面的(de)同(tong)時，路基(ji)墊層正在(zai)同(tong)步形成。

據該項目負責人(ren)介紹，該施工(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)屬環保(bao)節(jie)能(neng)新(xin)型工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)，在(zai)全(quan)(quan)國都(dou)算新(xin)技術，在(zai)山西(xi)、內蒙等地(di)己(ji)經成功使用(yong)，但在(zai)江西(xi)宜春還是(shi)首(shou)次(ci)采(cai)(cai)(cai)(cai)用(yong)。按(an)老(lao)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)施工(gong)(gong)(gong)(gong)(gong)，需要將原破損水泥路面全(quan)(quan)部挖除運走(zou)，并重新(xin)購(gou)買碎(sui)石用(yong)做路基墊層(ceng)，施工(gong)(gong)(gong)(gong)(gong)周期長(chang)，采(cai)(cai)(cai)(cai)購(gou)成本大。而采(cai)(cai)(cai)(cai)用(yong)新(xin)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)后，一(yi)是(shi)對環境保(bao)護(hu)起到(dao)促進作用(yong)，原破損水泥路面經就地(di)再生施工(gong)(gong)(gong)(gong)(gong)后，可(ke)直接(jie)用(yong)做墊層(ceng)使用(yong)，幾乎不需要重新(xin)填埋碎(sui)石；二是(shi)節(jie)約(yue)了(le)采(cai)(cai)(cai)(cai)購(gou)成本，該改建工(gong)(gong)(gong)(gong)(gong)程(cheng)項目全(quan)(quan)長(chang)14.68公(gong)里(li)，每公(gong)里(li)所需碎(sui)石墊層(ceng)1200立方，按(an)每方85元計算，共節(jie)約(yue)碎(sui)石采(cai)(cai)(cai)(cai)購(gou)成本149.736萬元；三是(shi)節(jie)省了(le)人(ren)工(gong)(gong)(gong)(gong)(gong)和縮短了(le)施工(gong)(gong)(gong)(gong)(gong)時(shi)間，原工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)需4個月(yue)才能(neng)完成墊層(ceng)施工(gong)(gong)(gong)(gong)(gong)，而采(cai)(cai)(cai)(cai)用(yong)水泥破碎(sui)機(ji)新(xin)工(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)施工(gong)(gong)(gong)(gong)(gong)只要2個月(yue)就可(ke)以完成全(quan)(quan)線(xian)墊層(ceng)施工(gong)(gong)(gong)(gong)(gong)任務(wu)。
