Description

工业化处理淤泥渣土的方法
技术领域
　　本发明涉及一种用于处理城市建设过程中产生的淤泥渣土的处理方法，尤其是在城市建设中挖出的泥土，如地铁施工、房屋建筑挖地基等产生的渣土的处理方法。
技术背景
　　地铁建设和高层楼房建筑是一个城市飞速发展的标志。在地铁建设和高层楼房建筑中，必然会产生大量的被挖掘出来的泥土。现在处理这类泥土的方法只有一种方式，就是在城市的周边地带，适合堆土的地方建立若干泥土受纳场。把城市建设过程中产生的泥土直接通过泥土车送到这些受纳场填埋，这种处理方法其实质上就是把需要建设的地方挖掘出来的泥土转运到了暂时不需要进行城市建设的地方。可是，在城市周边适合于用来作为受纳场地方，也越来越少，不得已，只能将现有受纳场超负荷运行，形成人为的山体，这种人为的山体土质相对疏松，一旦受到地理环境变化和天气因素的影响，如地震或长时间下雨，很容易引起人为山体滑坡，造成不可估量的人为损失。如今年夏天，南方某市的这种受纳场的人为山体滑坡，就几乎将山体周边的几个工业区全部毁埋，造成了巨大的人员伤亡和财产损失。
　　中国专利文献CN1868597A公开了一种建筑垃圾的综合处理方法,其处理步骤包括:将建筑垃圾适当破碎后,将其中的金属、竹、木、塑料等杂物分选检出,然后将剩余材料倒入具有三级分层的分格筛架的清洗池中,用水清洗并搅拌,物料经三级分层的分格筛架筛选后,由下至上分离成泥沙浆、中、小颗粒沙石粒和大块状物料分层排出,泥沙浆还通过多级机械分选筛生产线,继续筛选分离成泥浆和沙、石粒;分离出来的大块状物料再送至破碎机破碎,破碎后的物料再经三级筛架分级筛选,分离成粉状物和小、中、大颗粒沙石粒;而分离出来的泥浆则输送入沉淀池中沉淀,干燥成优质粘土,水则排入循环池循环利用。这种方法虽然具有处理后的所有物料可循环综合利用,符合环保和可持续发展的理念的优点，但是，在实际实施过程中，由于其首先要将建筑垃圾适当破碎后,然后再将其中的金属、竹、木、塑料等杂物分选检出,这个过程处理速度很慢，由于地铁或高层建筑都是很短的时间内会出现大量的泥土，如果都先破碎，再分选金属、竹、木、塑料等杂物，这就需要大量的堆场来昨时存储待处理泥砂，这给寸土寸金的城市用地来说，还是不太适合的。
　　因此，如何快速的工业化处理由城市建设所产生的泥土，使其变废为宝是摆在人们面前的一个亟待解决的问题。
发明内容
　　为了解决现有技术的不足，本发明向社会提供一种可以将城市建设过程中产生的泥土，进行快速化工业处理，使其变为建筑用料和工业泥土的工业化处理淤泥渣土的方法。
本发明的技术方案是：提供一种工业化处理淤泥渣土的方法，主要适合于用来处理城市建设中挖掘出来的泥砂土，包括如下步骤：
（1）、泥砂初处理步骤

试验条件，被测试软陶瓷及对照样品被制成长65 cm×宽5cm的样条，作好50cm标记；在温度为21±1℃和湿度为65±2%的条件下平衡4小时。
测试，连续慢慢拉伸至30N，停止3秒，慢慢抬起后停止3秒再拉伸，往复三次，第四次拉伸后测量标记尺寸。
伸长率计算，伸长率％=（拉伸后尺寸-50厘米）/50厘米。
软陶瓷的回复率的测定方法：
试验器材，定时器、米尺和软尺（精确至0.1MM）、静力伸长测试仪；
试验条件，被测试软陶瓷及对照样品被制成长65 cm×宽5cm的样条，在温度为21±1℃和湿度为65±2%的条件下平衡4小时。

将被测样品在原长的基础上拉伸伸长率的80%，固定半小时后松开，1小时后测量其长度L1。
例如，伸长率是40%，则拉伸至50+50×40%×80%厘米，即66厘米。
弹性伸长回复率=（L1-50厘米）/50厘米。
耐磨性能指标测定：按照国标GB/T 12988《无机地面材料磨损性能实验方法》进行。
