本实用新型专利技术涉及一种用塑料膨胀套管进行钻孔护壁的专用膨胀套管,属于地质勘探用钻进技术领域。技术方案是:包含塑料膨胀套管管体(11)和通槽(12),塑料膨胀套管管体的壁上设有一个或一个以上通槽;用高强度塑料膨胀套管取代钢套管,在需护壁的孔段形成一个带有塑料膨胀套管的人造水泥孔壁,可以防塌、防漏水、防湧水、防掉块,保证下一步的钻探工作继续进行。本实用新型专利技术克服了钢膨胀套管膨胀时需要很高的拉力10-15吨,而且要配之复杂的膨胀工具问题,采用高强度塑料膨胀套管,不用配合膨胀工具,即可实现快速、可靠、低成本的质钻孔护壁,用一个口径将钻孔钻完,极大的提高了钻探工作的效率。(*该技术在2021年保护过期,可自由使用*)

The utility model relates to a special expansion sleeve for drilling and wall protection by using a plastic expansion sleeve

The utility model relates to a special expansion sleeve for drilling and wall protection with a plastic expansion sleeve, belonging to the drilling technical field of geological exploration. The technology comprises plastic expansion casing (11) and groove (12), plastic expansion casing is arranged on the wall of one or more grooves; high strength plastic expansion casing to replace the steel casing, forming a man-made cement hole wall with plastic expansion casing in hole section the wall, can prevent the collapse, prevention, anti water, anti Water Leakage off block, ensure the next step to continue drilling work. The utility model overcomes the defects of steel expansion casing expansion need high tensile 10-15 tons, and problems with complex expansion tool, high strength plastic expansion casing, not with the expansion tool, can realize fast, reliable and low cost mass with a diameter of borehole wall protection, drilling drilling, great to improve the efficiency of drilling work.
