现有的稳定土拌和机均采用水泵供水，用回水阀来控制加水量。比较先进的系统也仅仅是在供水回路上加装一只水表用来显示供水量，但难以控制成品料的含水量。施工时，若操作人员忘了开水泵电机，会导致一部分成品料含水量不足；或因骨料含水量变化，而操作手未能及时知道成品料
Existing stabilized soil mixing machines are used pump water supply, with a backwater valve to control the amount of water. The more advanced system just adds a water meter to the water supply circuit to show the water supply, but it is difficult to control the water content of the finished product. Construction, if the operator forgot to open the pump motor, will result in part of the finished material moisture content is not enough; or due to changes in aggregate moisture content, and the operator failed to timely know the finished product
