拖泵施工两大注意事项

日常生活当中,全自动化机械化施工代替了传统式人力施工。拖泵也成为现如今混(hun)凝土施(shi)工(gong)(gong)中(zhong)的(de)高(gao)效大师。小(xiao)编(bian)在奔赴湖南益阳的(de)施(shi)工(gong)(gong)现场时,一(yi)些(xie)正在使(shi)用三民重科(ke)拖泵施(shi)工(gong)(gong)的(de)泵友(you)(you)经常会向小(xiao)编(bian)咨询一(yi)些(xie)有关(guan)拖泵相关(guan)的(de)问题,其(qi)中(zhong)发现许多泵友(you)(you)只在意(yi)机械(xie)设(she)备如何通过操作达到(dao)高(gao)效施(shi)工(gong)(gong)的(de)目的(de)。但是忽略了拖泵注意(yi)事(shi)项。因此(ci)小(xiao)编(bian)希(xi)望通过下面该篇短文,能够让各位更加(jia)明白、了解混(hun)凝土施(shi)工(gong)(gong)中(zhong),塌落(luo)度的(de)选择(ze)与(yu)混(hun)凝土的(de)配合比(bi)其(qi)中(zhong)的(de)利害(hai)关(guan)系。

拖泵

拖泵塌落(luo)度的(de)选(xuan)择

普通混凝(ning)土(tu)施工的方(fang)式是塌落度是根据捣实(shi)方(fang)式确定的,即(ji)要求泵(beng)(beng)(beng)送(song)(song)效率高、不阻(zu)塞,还要考虑(lv)其(qi)可泵(beng)(beng)(beng)送(song)(song)性。而泵(beng)(beng)(beng)送(song)(song)混凝(ning)土(tu)除了考虑(lv)捣实(shi)施工外,如塌落度过大,混凝(ning)土(tu)拌合物容易离(li)析(xi),造成堵管。泵(beng)(beng)(beng)送(song)(song)混凝(ning)土(tu)的塌落度范围(wei)一般应控(kong)制在(8-23)cm,对于长距离(li)、大高度的泵(beng)(beng)(beng)送(song)(song)一般控(kong)制在18cm左(zuo)右。

拖(tuo)泵需要严格控(kong)制(zhi)混(hun)凝土的配合(he)比

严格缩短拖(tuo)泵在(zai)(zai)泵送(song)(song)前(qian)的(de)(de)运(yun)(yun)输(shu)(shu)(shu)时间,一般要求在(zai)(zai)搅(jiao)(jiao)拌(ban)后(hou)(hou)90min内完成泵送(song)(song);保(bao)(bao)证混凝(ning)(ning)土(tu)(tu)(tu)的(de)(de)均质性,为(wei)保(bao)(bao)障混凝(ning)(ning)土(tu)(tu)(tu)泵送(song)(song)顺利进行(xing),搅(jiao)(jiao)拌(ban)好的(de)(de)混凝(ning)(ning)土(tu)(tu)(tu)从搅(jiao)(jiao)拌(ban)点到(dao)泵送(song)(song)处(chu)的(de)(de)运(yun)(yun)输(shu)(shu)(shu)机(ji)具(ju)和方法应保(bao)(bao)证在(zai)(zai)运(yun)(yun)输(shu)(shu)(shu)过程中混凝(ning)(ning)土(tu)(tu)(tu)不产(chan)生离析,如(ru)用(yong)(yong)无搅(jiao)(jiao)拌(ban)装置的(de)(de)机(ji)具(ju)运(yun)(yun)输(shu)(shu)(shu),到(dao)达泵送(song)(song)处(chu)后(hou)(hou),须(xu)经搅(jiao)(jiao)拌(ban)后(hou)(hou)方可喂入混凝(ning)(ning)土(tu)(tu)(tu)泵的(de)(de)料斗(dou)。如(ru)用(yong)(yong)搅(jiao)(jiao)拌(ban)车应保(bao)(bao)证运(yun)(yun)输(shu)(shu)(shu)能力(li)大于泵送(song)(song)能力(li),保(bao)(bao)证泵送(song)(song)不中断。采用(yong)(yong)符合(he)标准的(de)(de)水泥,不能泵送(song)(song)速凝(ning)(ning)混凝(ning)(ning)土(tu)(tu)(tu)。塌(ta)落度偏差过大和品质显著变坏的(de)(de)混凝(ning)(ning)土(tu)(tu)(tu)不得进入料斗(dou)。严禁(jin)向料斗(dou)加水。

三(san)民(min)重科提(ti)醒各位,确定泵送混(hun)凝(ning)土(tu)的(de)(de)(de)配合比时,需考虑管道输送的(de)(de)(de)特点(dian),以及在(zai)水泥(ni)用量(liang)、塌(ta)落度、砂率等方面等处理。泵送混(hun)凝(ning)土(tu)设计的(de)(de)(de)目的(de)(de)(de)是根据(ju)工(gong)程对混(hun)凝(ning)土(tu)性能的(de)(de)(de)要求(qiu)和混(hun)凝(ning)土(tu)泵送的(de)(de)(de)要求(qiu)。这样拖泵施(shi)工(gong)才能既高效有(you)安全,前言万(wan)语道不尽!信既有(you),不信则(ze)无!如果您(nin)还有(you)什么疑惑,可以关注我(wo)们的(de)(de)(de)关注号“三(san)民(min)重科”,有(you)专(zhuan)业的(de)(de)(de)机(ji)械(xie)设备专(zhuan)家在(zai)线解惑哟(yo)!
