日前，上海城建路(lu)(lu)橋集團在G15公路(lu)(lu)朱(zhu)橋收費站綜(zong)合大修改造工(gong)(gong)(gong)程施工(gong)(gong)(gong)中(zhong)采用(yong)新(xin)技(ji)術“水(shui)力清拆(chai)(chai)(chai)工(gong)(gong)(gong)藝”，取代傳統混(hun)凝(ning)土(tu)(tu)破(po)拆(chai)(chai)(chai)工(gong)(gong)(gong)藝，具有環(huan)保、減(jian)耗等(deng)優點。目前國內鋼筋混(hun)凝(ning)土(tu)(tu)維修及拆(chai)(chai)(chai)除工(gong)(gong)(gong)程普遍采用(yong)人工(gong)(gong)(gong)、風鎬、電鎬、鎬頭機、切割等(deng)傳統工(gong)(gong)(gong)藝。而(er)在G15公路(lu)(lu)朱(zhu)橋收費站綜(zong)合大修改造工(gong)(gong)(gong)程中(zhong)使用(yong)的(de)“水(shui)力清拆(chai)(chai)(chai)工(gong)(gong)(gong)藝”是一項(xiang)快速有效(xiao)的(de)混(hun)凝(ning)土(tu)(tu)清除工(gong)(gong)(gong)藝，利(li)用(yong)高壓水(shui)穿(chuan)透混(hun)凝(ning)土(tu)(tu)空隙，并將其破(po)除。這種工(gong)(gong)(gong)藝被運(yun)用(yong)于新(xin)老(lao)橋搭接(jie)部(bu)位(wei)的(de)混(hun)凝(ning)土(tu)(tu)拆(chai)(chai)(chai)除，在有效(xiao)保護結構中(zhong)的(de)鋼筋不被鑿壞(huai)的(de)同時，過程中(zhong)無揚(yang)塵、安全環(huan)保，拆(chai)(chai)(chai)除后的(de)混(hun)凝(ning)土(tu)(tu)表面能(neng)更(geng)好的(de)與(yu)新(xin)材料結合，拆(chai)(chai)(chai)除鋼筋還可重復利(li)用(yong)，符合綠色施工(gong)(gong)(gong)理念。
