贴砾滤水管(简称贴砾管是近年研制成的一种新型滤水管。是以钢管做衬管,用合成树脂将一定粒径的石英砂粘到打眼衬管上制成的。具有良好的透水性和可靠的滤砂性。适用于粗砂、中砂、细砂、粉砂等含水地层,较好的解决了粉、细砂地层成井涌砂问题和深孔填砾不均匀、不准确甚至壅塞架桥等技术难 Sticky gravel filter pipe (referred to as sticky gravel pipe is developed in recent years into a new type of filter pipe is made of steel pipe liner, synthetic resin will be a certain diameter of quartz sand stick to the liner made of drilling. Has a good Water permeability and reliable filter sand.Applicable to coarse sand, sand, fine sand, silt and other aquifers, a better solution to the powder, fine sand formation into the well and the problem of sand filling and uneven deep-hole gravel, inaccurate Even congested bridges and other technical difficulties
