日(ri)前，上海城建(jian)路(lu)(lu)橋集團在G15公(gong)路(lu)(lu)朱橋收(shou)費(fei)站綜合(he)大(da)修改造工(gong)(gong)(gong)(gong)程(cheng)施(shi)工(gong)(gong)(gong)(gong)中(zhong)采用(yong)新(xin)技(ji)術“水(shui)(shui)力清拆(chai)(chai)(chai)工(gong)(gong)(gong)(gong)藝(yi)(yi)”，取代(dai)傳統混(hun)凝(ning)土破拆(chai)(chai)(chai)工(gong)(gong)(gong)(gong)藝(yi)(yi)，具有環保(bao)、減耗等(deng)優點。目前國內鋼(gang)筋混(hun)凝(ning)土維(wei)修及(ji)拆(chai)(chai)(chai)除工(gong)(gong)(gong)(gong)程(cheng)普(pu)遍(bian)采用(yong)人(ren)工(gong)(gong)(gong)(gong)、風(feng)鎬、電鎬、鎬頭機(ji)、切割等(deng)傳統工(gong)(gong)(gong)(gong)藝(yi)(yi)。而在G15公(gong)路(lu)(lu)朱橋收(shou)費(fei)站綜合(he)大(da)修改造工(gong)(gong)(gong)(gong)程(cheng)中(zhong)使用(yong)的(de)(de)“水(shui)(shui)力清拆(chai)(chai)(chai)工(gong)(gong)(gong)(gong)藝(yi)(yi)”是一項(xiang)快速有效(xiao)的(de)(de)混(hun)凝(ning)土清除工(gong)(gong)(gong)(gong)藝(yi)(yi)，利用(yong)高壓水(shui)(shui)穿透混(hun)凝(ning)土空隙(xi)，并將(jiang)其(qi)破除。這種(zhong)工(gong)(gong)(gong)(gong)藝(yi)(yi)被運用(yong)于新(xin)老橋搭(da)接部位的(de)(de)混(hun)凝(ning)土拆(chai)(chai)(chai)除，在有效(xiao)保(bao)護(hu)結(jie)構中(zhong)的(de)(de)鋼(gang)筋不(bu)被鑿壞的(de)(de)同時(shi)，過程(cheng)中(zhong)無揚塵、安全環保(bao)，拆(chai)(chai)(chai)除后的(de)(de)混(hun)凝(ning)土表面能更好的(de)(de)與新(xin)材料(liao)結(jie)合(he)，拆(chai)(chai)(chai)除鋼(gang)筋還可重(zhong)復利用(yong)，符合(he)綠色施(shi)工(gong)(gong)(gong)(gong)理(li)念。
