我单位所勘探的矿区,由于地层和水文情况的关系,对施工完了的见矿钻孔,均需严格封孔.如何把搅拌好的水泥砂浆送到规定的孔深部位,是保证封孔质量的重要环节.为此,我们在不断实践中,试制成功了一种托盘式送浆器,经过几个孔的实际应用,效果良好.一、送浆器结构(见附图所示): Due to the relationship between strata and hydrological conditions, all the mined areas explored by our unit should be strictly sealed for the see-finished mine borehole.How to ensure that the grouted cement mortar is delivered to the deep part of the hole An important part of our practice.Therefore, we continue to practice, the trial success of a tray-type slurry feeder, after several holes of practical application, the effect is good. First, the slurry feeder structure (see photo):
