混凝土切(qie)(qie)割(ge)隨(sui)著城市化發(fa)展(zhan)的(de)加快，城市建設(she)越來(lai)越多(duo)。在大城市里地面(mian)已不(bu)能(neng)滿足交通(tong)要(yao)求了，向上延伸至高(gao)架、輕軌，向下是地鐵。有些高(gao)架在現在看來(lai)已成為制約城市發(fa)展(zhan)的(de)因素。對(dui)這(zhe)些高(gao)架進(jin)行改建、不(bu)可(ke)避免地要(yao)拆(chai)除一部分(fen)，同(tong)時又要(yao)保證一部分(fen)不(bu)受影響并可(ke)重(zhong)新利用，這(zhe)已經成為一個擺在我們面(mian)前的(de)難題。在傳統(tong)的(de)拆(chai)除施(shi)工對(dui)此無能(neng)為力(li)時，先進(jin)的(de)鋼筋混凝土切(qie)(qie)割(ge)法(fa)有安全、高(gao)效、環保的(de)特點(dian)。

　　鋼筋混凝土切(qie)(qie)(qie)(qie)割技術主要有(you)(you)碟(die)式切(qie)(qie)(qie)(qie)割法和鉆石(shi)(shi)(shi)(shi)鋼線(xian)切(qie)(qie)(qie)(qie)割法。鉆石(shi)(shi)(shi)(shi)鋼線(xian)切(qie)(qie)(qie)(qie)割法具有(you)(you)更快(kuai)的(de)(de)(de)速度、更大(da)的(de)(de)(de)靈活性和更低的(de)(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)噪音。特別是在(zai)建(jian)筑改造工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)中(zhong)得到越來越多的(de)(de)(de)應用(yong)。碟(die)式切(qie)(qie)(qie)(qie)割法打破傳統的(de)(de)(de)風(feng)鎬(hao)鑿(zao)除后(hou)氣(qi)割或定向(xiang)爆(bao)破的(de)(de)(de)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)方法，采(cai)用(yong)帶有(you)(you)金(jin)剛(gang)石(shi)(shi)(shi)(shi)顆粒的(de)(de)(de)切(qie)(qie)(qie)(qie)割碟(die)片切(qie)(qie)(qie)(qie)割，施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)切(qie)(qie)(qie)(qie)口(kou)整齊、平直，無須事后(hou)加工(gong)(gong)(gong)(gong)(gong)處理(li)，不受施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)場地(di)、環(huan)境保(bao)護、工(gong)(gong)(gong)(gong)(gong)期、安(an)全(quan)原因等(deng)條(tiao)件限制(zhi)，被廣(guang)泛應用(yong)于各類大(da)型(xing)建(jian)筑物的(de)(de)(de)結(jie)構改造以及(ji)切(qie)(qie)(qie)(qie)割施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)中(zhong)。鋼線(xian)切(qie)(qie)(qie)(qie)割法設備(bei)由大(da)功率油(you)壓(ya)機(ji)、傳動定位滑輪及(ji)帶有(you)(you)金(jin)剛(gang)石(shi)(shi)(shi)(shi)鋸齒的(de)(de)(de)鋼線(xian)組合而成，油(you)壓(ya)馬達通(tong)過(guo)傳動滑輪帶動鋼線(xian)圍繞被切(qie)(qie)(qie)(qie)割物體高(gao)速旋轉(zhuan)進行切(qie)(qie)(qie)(qie)割，具有(you)(you)施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)作業速度快(kuai)、噪音低、無震(zhen)動、無粉塵(chen)廢氣(qi)污染(ran)等(deng)優點(dian)，而且(qie)切(qie)(qie)(qie)(qie)口(kou)平直光滑，無須做善(shan)后(hou)加工(gong)(gong)(gong)(gong)(gong)處理(li)。采(cai)用(yong)該技術，對于一(yi)些對施(shi)(shi)工(gong)(gong)(gong)(gong)(gong)有(you)(you)特殊要求的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)，如工(gong)(gong)(gong)(gong)(gong)期緊迫、環(huan)保(bao)要求高(gao)，以及(ji)一(yi)些大(da)型(xing)混凝土結(jie)構拆卸、切(qie)(qie)(qie)(qie)割的(de)(de)(de)工(gong)(gong)(gong)(gong)(gong)程(cheng)(cheng)，這些難(nan)題(ti)即可迎(ying)刃(ren)而解(jie)。

　　混凝土(tu)(tu)切割是(shi)采(cai)用水(shui)冷卻金剛石軌道或繩鋸(ju)切割機對混凝土(tu)(tu)進行開洞、拆除，施工速度快，噪音(yin)小，無震(zhen)動(dong)，質量好(hao)，對建筑結構(gou)沒有影響(xiang)，是(shi)取(qu)代電(dian)錘、風鎬、人工釬打等震(zhen)動(dong)較大機具施工的先進工藝。
