現在(zai)(zai)工(gong)程中(zhong)斜(xie)屋面(mian)已經越來越常見了(le),近日,三民重科(ke)攪(jiao)拌(ban)車(che)載泵在(zai)(zai)衡陽7層商品(pin)房建設(she)中(zhong),進行后的斜(xie)屋面(mian)混凝土(tu)澆(jiao)(jiao)筑(zhu)工(gong)作。通常來說,澆(jiao)(jiao)筑(zhu)斜(xie)屋面(mian)在(zai)(zai)施工(gong)上有一定的困(kun)難(nan),那(nei)么攪(jiao)拌(ban)車(che)載泵是如何助(zhu)力完成斜(xie)屋面(mian)澆(jiao)(jiao)筑(zhu)的呢(ni)?
眾所周知,斜屋面澆筑混凝土不僅對施工工藝有所要求,對混凝土質量也需要達到一定的標準。首先混凝土的要求應該是干硬性的,就是坍落度要小,流動性小。普通的攪拌機一般難以攪拌黏性混凝土,而三民重科攪拌車載泵,作為一種連續雙臥軸強制攪拌輸送泵,采用(yong)雙(shuang)臥(wo)(wo)軸攪(jiao)拌(ban)(ban)(ban)系統,在砂石進入攪(jiao)拌(ban)(ban)(ban)筒內后,由雙(shuang)臥(wo)(wo)軸進行(xing)攪(jiao)拌(ban)(ban)(ban),勁大,力足,攪(jiao)拌(ban)(ban)(ban)出來的混(hun)凝土(tu)(tu)更均(jun)勻。這種既能攪(jiao)拌(ban)(ban)(ban)高(gao)(gao)(gao)強混(hun)凝土(tu)(tu),又能攪(jiao)拌(ban)(ban)(ban)干硬性混(hun)凝土(tu)(tu)的設備(bei),攪(jiao)拌(ban)(ban)(ban)時(shi)間短,生產率高(gao)(gao)(gao),從施工(gong)圖中可看到,混(hun)凝土(tu)(tu)從泵管噴涌而(er)出,量多(duo),并且速度快(kuai),其高(gao)(gao)(gao)效的施工(gong)效率引人注目(mu)。
在(zai)施(shi)工(gong)(gong)工(gong)(gong)藝方(fang)面(mian),施(shi)工(gong)(gong)人員(yuan)將管道接入(ru)樓(lou)面(mian)后,澆筑順序應該從(cong)上往(wang)(wang)下澆,從(cong)斜(xie)屋(wu)面(mian)頂部(bu)開(kai)始澆鋪,讓混凝土(tu)往(wang)(wang)下自然流(liu)淌鋪滿整個斜(xie)屋(wu)面(mian);盡量不(bu)留(liu)(liu)或(huo)少留(liu)(liu)施(shi)工(gong)(gong)縫(feng),不(bu)能避免時(shi),施(shi)工(gong)(gong)縫(feng)留(liu)(liu)成階梯型,用水泥砂(sha)漿做(zuo)好接槎,以免日(ri)后屋(wu)面(mian)漏水;另(ling)外,在(zai)屋(wu)面(mian)上由(you)于振(zhen)搗困難,振(zhen)搗時(shi)動作一(yi)定(ding)要快,多(duo)點、密集振(zhen)搗,如果斜(xie)屋(wu)面(mian)坡度較大,則可用板錘(chui)拍打(da)混凝土(tu)以代替振(zhen)搗。
