    烟囱新建工程在灌注时要注意哪些细节?

    1.桩基施(shi)工墙(qiang)烟囱的新施(shi)工强度等级应与桩基烟囱相同。挡土墙(qiang)应高出地面(mian)至(zhi)少30cm,并仔(zi)细检查房间(jian)墙(qiang)壁是否漏水或漏水。

    2.烟(yan)(yan)囱(cong)新(xin)(xin)建(jian)施工(gong)(gong)(gong)(gong)前应收集(ji)施工(gong)(gong)(gong)(gong)配(pei)合(he)比的原材(cai)料,经检测合(he)格后,分(fen)为(wei)人(ren)工(gong)(gong)(gong)(gong)挖孔桩和钻孔灌注(zhu)桩混合(he)设计。一般来(lai)说,人(ren)工(gong)(gong)(gong)(gong)挖孔桩烟(yan)(yan)囱(cong)新(xin)(xin)建(jian)施工(gong)(gong)(gong)(gong)平民窟比人(ren)工(gong)(gong)(gong)(gong)挖孔桩烟(yan)(yan)囱(cong)大,但无论(lun)新(xin)(xin)建(jian)何种烟(yan)(yan)囱(cong),都必(bi)须(xu)满足施工(gong)(gong)(gong)(gong)过(guo)程(cheng)的具(ju)体(ti)要求,包括烟(yan)(yan)囱(cong)新(xin)(xin)建(jian)施工(gong)(gong)(gong)(gong)平民窟、初沉时间(jian)、终沉时间(jian)等。其中(zhong),重(zhong)要的是新(xin)(xin)烟(yan)(yan)囱(cong)建(jian)设项目的粘度和含水量保持良好。

    3.烟(yan)囱(cong)(cong)(cong)(cong)新(xin)(xin)(xin)建(jian)施(shi)工管道畅(chang)通,仔细(xi)检查孔(kong)底是(shi)否有积(ji)水(shui)(shui)或(huo)沉(chen)淀物。沉(chen)积(ji)物通常(chang)更容易清除,但地(di)下水(shui)(shui)位(wei)越高(gao),清除越难。一(yi)是(shi)地(di)下水(shui)(shui)量(liang)小,所以在(zai)烟(yan)囱(cong)(cong)(cong)(cong)新(xin)(xin)(xin)建(jian)建(jian)设项目(mu)的(de)(de)管道流动之前,海绵、毛毡等。尽可能(neng)多的(de)(de)用(yong)来吸(xi)干积(ji)水(shui)(shui)。一(yi)旦(dan)水(shui)(shui)被吸(xi)干,烟(yan)囱(cong)(cong)(cong)(cong)新(xin)(xin)(xin)建(jian)建(jian)设项目(mu)的(de)(de)管道流可以立(li)即进(jin)行。新(xin)(xin)(xin)建(jian)二次烟(yan)囱(cong)(cong)(cong)(cong)需(xu)要大量(liang)水(shui)(shui)泥,浇筑高(gao)度(du)应严(yan)格控(kong)制,新(xin)(xin)(xin)建(jian)烟(yan)囱(cong)(cong)(cong)(cong)也应充(chong)分振实。如果(guo)地(di)下水(shui)(shui)量(liang)太大,无法(fa)用(yong)海绵或(huo)毛毡吸(xi)干,可考虑将(jiang)钻(zuan)孔(kong)桩倒入水(shui)(shui)下烟(yan)囱(cong)(cong)(cong)(cong)的(de)(de)新(xin)(xin)(xin)结构中。
