description The utility model belongs to the technical field of mine production protection equipment and specifically relates to an exploring and draining jacket pipe. It includes a first pipe, follows the banding friction butt piece that its circumferencial direction interval was equipped with a plurality of and first tub of length direction parallel arrangement in the outside of first pipe, and the right -hand member of each butt piece that rubs links to each other with the first pipe that corresponds position department respectively, and the butt spare looks butt in first outside of tubes side is established with a thread bush respectively to the left end, is equipped with the passageway of confession thick liquid inflow drilling on butt spare. Its simple structure, reasonable in design can combineclosely sleeve pipe and drilling inner wall, prevents effectively that the sleeve pipe from being rush out to, the seal is good between sleeve pipe and the drilling inner wall, can effectively prevent to metal run out or go
