混凝土机械化泵送已经成为全国各地主流的施工方式，其施工效率高、安全性大，一方面解放了劳动力，另一方面，降低了劳动强度。但是小编混迹个各地中发现，一些各地使用同款汽车混凝土输送泵的(de)(de)情况下，泵(beng)送(song)(song)效(xiao)率(lv)、工作(zuo)时长有出入(ru)。小(xiao)编对这(zhei)类问题进(jin)行了一番研究，也跟(gen)相(xiang)关技术人员咨询后，了解到在高层(ceng)施工中，布(bu)管方式不同与(yu)泵(beng)送(song)(song)高度存在密切联系(xi)，合理(li)有效(xiao)的(de)(de)进(jin)行高层(ceng)泵(beng)送(song)(song)管道布(bu)局，可(ke)以(yi)加快混凝泵(beng)送(song)(song)效(xiao)率(lv)。一下是(shi)小(xiao)编整理(li)出来的(de)(de)一些布(bu)管细(xi)节与(yu)方法！

汽车混凝土输送泵高层布管原(yuan)则：

输送(song)管(guan)(guan)(guan)(guan)应选用(yong)(yong)(yong)超(chao)高(gao)压输送(song)管(guan)(guan)(guan)(guan)，目前(qian)有8mm、9mm、12mm等规格(ge)，采用(yong)(yong)(yong)法兰头连接(jie)(jie)(jie);有条(tiao)件(jian)的(de)可(ke)(ke)在(zai)砼管(guan)(guan)(guan)(guan)固(gu)(gu)(gu)定(ding)(ding)(ding)装(zhuang)置(zhi)上加装(zhuang)减震器，垂(chui)直立管(guan)(guan)(guan)(guan)可(ke)(ke)采用(yong)(yong)(yong)在(zai)墙(qiang)壁上预埋高(gao)强度(du)(du)钢板，U码焊接(jie)(jie)(jie)在(zai)钢板上，再(zai)用(yong)(yong)(yong)砼管(guan)(guan)(guan)(guan)固(gu)(gu)(gu)定(ding)(ding)(ding)装(zhuang)置(zhi)固(gu)(gu)(gu)定(ding)(ding)(ding)牢固(gu)(gu)(gu)。采用(yong)(yong)(yong)液压截止(zhi)阀两(liang)套，一(yi)套安装(zhuang)在(zai)泵的(de)出口端(duan)6～10m处(chu)(chu)，一(yi)套安装(zhuang)在(zai)第二层(ceng)，阻止(zhi)垂(chui)直管(guan)(guan)(guan)(guan)道(dao)(dao)内混凝土回流，用(yong)(yong)(yong)于保养、维修及水(shui)洗，水(shui)平(ping)(ping)管(guan)(guan)(guan)(guan)与竖直管(guan)(guan)(guan)(guan)道(dao)(dao)长度(du)(du)之比应在(zai)4:1左右;水(shui)平(ping)(ping)管(guan)(guan)(guan)(guan)道(dao)(dao)长度(du)(du)无(wu)法满足时，可(ke)(ke)以在(zai)楼(lou)层(ceng)中(zhong)间加适(shi)当(dang)的(de)水(shui)平(ping)(ping)管(guan)(guan)(guan)(guan)来(lai)平(ping)(ping)衡(heng);每根输送(song)管(guan)(guan)(guan)(guan)在(zai)距两(liang)端(duan)500mm处(chu)(chu)用(yong)(yong)(yong)2个(ge)砼管(guan)(guan)(guan)(guan)固(gu)(gu)(gu)定(ding)(ding)(ding)装(zhuang)置(zhi)固(gu)(gu)(gu)定(ding)(ding)(ding)牢固(gu)(gu)(gu)、防止(zhi)管(guan)(guan)(guan)(guan)道(dao)(dao)因震动而(er)松动。水(shui)平(ping)(ping)—垂(chui)直弯管(guan)(guan)(guan)(guan)固(gu)(gu)(gu)定(ding)(ding)(ding)采用(yong)(yong)(yong)水(shui)泥支撑固(gu)(gu)(gu)定(ding)(ding)(ding)，两(liang)端(duan)再(zai)用(yong)(yong)(yong)砼管(guan)(guan)(guan)(guan)固(gu)(gu)(gu)定(ding)(ding)(ding)装(zhuang)置(zhi)固(gu)(gu)(gu)定(ding)(ding)(ding)牢固(gu)(gu)(gu)。垂(chui)直立管(guan)(guan)(guan)(guan)的(de)固(gu)(gu)(gu)定(ding)(ding)(ding)应先预埋高(gao)强度(du)(du)钢板，再(zai)焊接(jie)(jie)(jie)支座，每根3米管(guan)(guan)(guan)(guan)用(yong)(yong)(yong)2个(ge)支撑固(gu)(gu)(gu)定(ding)(ding)(ding)。垂(chui)直立管(guan)(guan)(guan)(guan)处(chu)(chu)要搭支架，以防堵管(guan)(guan)(guan)(guan)、爆管(guan)(guan)(guan)(guan)等异常时方(fang)便拆管(guan)(guan)(guan)(guan)。

汽车(che)混(hun)凝土输送(song)泵配管的(de)准备(bei)、使(shi)用要(yao)求：

布置管(guan)(guan)(guan)(guan)路(lu)时，应(ying)在保证顺利泵(beng)送(song)(song)(song)和正常输送(song)(song)(song)的前提下(xia)，尽量缩短距离，减(jian)少(shao)弯管(guan)(guan)(guan)(guan)，以减(jian)小输送(song)(song)(song)阻(zu)力。末端软管(guan)(guan)(guan)(guan)宜垂直放置，当(dang)必(bi)须水平(ping)放置时，切不(bu)(bu)可弯曲软管(guan)(guan)(guan)(guan)。高(gao)(gao)压(ya)(ya)、低压(ya)(ya)输送(song)(song)(song)管(guan)(guan)(guan)(guan)不(bu)(bu)得混装，高(gao)(gao)压(ya)(ya)泵(beng)必(bi)须使(shi)用(yong)高(gao)(gao)压(ya)(ya)管(guan)(guan)(guan)(guan)。不(bu)(bu)得使(shi)用(yong)有(you)损(sun)伤(shang)、裂纹或(huo)太薄(bo)的配(pei)(pei)管(guan)(guan)(guan)(guan)。配(pei)(pei)管(guan)(guan)(guan)(guan)壁厚磨(mo)损(sun)快的部位，要注意(yi)安全。对(dui)于125A高(gao)(gao)压(ya)(ya)管(guan)(guan)(guan)(guan)来(lai)说，高(gao)(gao)压(ya)(ya)施工时，泵(beng)出口(kou)附近的输送(song)(song)(song)管(guan)(guan)(guan)(guan)壁厚使(shi)用(yong)极限为(wei)4MM，浇灌现场与(yu)末端软管(guan)(guan)(guan)(guan)连接的配(pei)(pei)管(guan)(guan)(guan)(guan)壁厚不(bu)(bu)能低于3.5MM。
