Abstract
The invention relates to an underground cavern drainage blind ditch device and a construction method. A plurality of circular small holes are arranged on the wall of a rubber tube, and are arranged in a plum blossom mode or rectangularly along the length direction of the wall of the rubber tube; water filtering geotextile and waterproof geotextile wrap the outer wall of a joint of the rubber tube and a three-way or four-way rubber tube, one side, which is wrapped by the water filtering geotextile, of the rubber tube clings to a water seeping rock wall, and the other side, which is wrapped by the waterproof geotextile, of the rubber rube is far away from the water seeping rock wall; the rubber tube wrapped with the geotextile is fixed on a rock surface by stainless steel fixing clamps; the fixing clamps are mounted at intervals ranging from 20cm to 40cm; and two ends of each fixing clamp are nailed on the rock surface by drive pins. Construction is convenient, efficiency is high, construction procedures of a rubber drainage blind ditch are few, construction quality is reliable, a drainage effect is good, and the rubber tube has certain flexibility and can be laid along a water seeping belt of the rock wall closely. Seeped water can be ensured to be drained into an appointed drainage open ditch or a water-collecting well along the rubber drainage blind ditch.
