下向钻孔排水装置Downhole Drainage

技术领域technical field

本发明涉及下向钻孔排水装置，属于排水领域。The invention relates to a downward drilling drainage device, which belongs to the field of drainage.

背景技术Background technique

众所周知，下向钻孔施工时排水、排渣困难，如果遇上底板为含水岩系，则会造成钻孔内积水问题，造成负压的损耗和抽放效果的不好。As we all know, drainage and slag removal are difficult during downward drilling. If the bottom plate is a water-bearing rock system, it will cause water accumulation in the borehole, resulting in loss of negative pressure and poor drainage effect.
