日前，上海城建路(lu)橋(qiao)集團(tuan)在G15公路(lu)朱(zhu)橋(qiao)收費站綜(zong)合大修改造工(gong)(gong)程施工(gong)(gong)中采用新(xin)技術“水(shui)力清拆(chai)工(gong)(gong)藝”，取代傳統(tong)混(hun)(hun)凝(ning)土(tu)破(po)拆(chai)工(gong)(gong)藝，具有環保、減耗等(deng)優點。目前國內鋼筋(jin)(jin)混(hun)(hun)凝(ning)土(tu)維修及拆(chai)除工(gong)(gong)程普遍采用人工(gong)(gong)、風鎬(hao)、電鎬(hao)、鎬(hao)頭機、切割等(deng)傳統(tong)工(gong)(gong)藝。而在G15公路(lu)朱(zhu)橋(qiao)收費站綜(zong)合大修改造工(gong)(gong)程中使用的“水(shui)力清拆(chai)工(gong)(gong)藝”是一項快速有效的混(hun)(hun)凝(ning)土(tu)清除工(gong)(gong)藝，利用高壓水(shui)穿透混(hun)(hun)凝(ning)土(tu)空隙，并將其(qi)破(po)除。這種工(gong)(gong)藝被運用于新(xin)老(lao)橋(qiao)搭接部(bu)位的混(hun)(hun)凝(ning)土(tu)拆(chai)除，在有效保護結構(gou)中的鋼筋(jin)(jin)不被鑿壞的同時，過程中無揚塵、安(an)全環保，拆(chai)除后(hou)的混(hun)(hun)凝(ning)土(tu)表面能更(geng)好(hao)的與新(xin)材(cai)料結合，拆(chai)除鋼筋(jin)(jin)還可重復利用，符合綠色施工(gong)(gong)理念。
