贴砾滤水管是一种新型水井过滤器,它是用合成树脂将一定粒径的砾石粘到钢制衬管上制成的,具有透水性好、滤砂可靠、使用方便等优点。目前西德、美、法、日等工业发达国家已大量用于水井建造工程;国内在地矿、冶金、煤炭、石油、水电等系统中已推广使用。贴砾管于1980年通过地质矿产部部级鉴定,现已将技术转让给保定市满城钻井公司。该公司1985年11月在无锡召开的国际钻探研讨会上,展出了4时、6时、8时和12时四种规格的产品。目前贴砾管多用于水井,拟推广应用于土坝测压管。
Sticky gravel filter pipe is a new type of water filter, which is a certain size of synthetic resin glued to steel liner made of steel, with good water permeability, filter sand, reliable, easy to use and so on. At present, industrialized countries such as West Germany, the United States, France, Japan and other developed countries have been extensively used for water well construction projects and have been widely promoted in the fields of geology and mining, metallurgy, coal, petroleum, hydropower and other systems. Stick gravel pipe passed the Ministry of Geology and Mineral Resources in 1980 at the ministerial level appraisal, the technology has been transferred to Baoding City Mancheng drilling company. At the International Drilling Symposium held in Wuxi in November 1985, the company exhibited four specifications at 4 o’clock, 6 o’clock, 8 o’clock and 12 o’clock. Currently used gravel pipe for water wells, intended to promote the use of earth dam piezometer.
