Title: Buried liner plate for shaft and corrugation making machine thereof
Inventor: MIYAZAKI MAMORU
IPC: E21D1/03
Filed: 1994-06-10
Abstract: PURPOSE:To promote the execution of corrugatization and the secureness of strength by closing an opening with an expansion deformation of a swelling material to be stored in the lower end of a liner plate, and bulgingly deforming this liner plate to the outside with the press head of a making machine. CONSTITUTION:After a drilling casing 1 is pressed in, a liner plate 2 is charged in a shaft, and thereby water in this shaft flows in from two openings 2c of a bottom plate 2a in the shaft and it is bottomed of this shaft. In this case, two swelling rubber parts 2d built in these openings 2 is impregnated and deformed, thereby closing all openings 2c, and thus they check an inflow of any underground water into the liner plate 2. Next, the liner plate 2 is formed into corrugated form by a making machine 3 as gradually pulling up the drilling casing 1. At that time, during stoppage of this intermittent pulling-up operations, the liner plate itself goes down along a guide rod 2b by means of operation of a hydraulic jack 3a. With this descent, each press head 3e is expanded in the radial direction by each displacement of rocker arms 3d and fixed arms 3c, whereby corrugation is bulgingly formable at the outside of the liner plate 2.
