The utility model relates to a hydrology prospecting is with ending pressure water stopper, it includes the center tube, sets up in the tray at center tube outside both ends, be provided with inflation rubber circle between two trays. The utility model discloses after filling in the passageway of the slip casting that hydrology prospecting formed in earlier stage, can be used to lamination power rivers and move excretory passageway, the stagnant water performance just can be exert for a long time to the exogenous strength of independence, after adopting inflation rubber as sealing material, inflation rubber chance water inflation forms to be hugged closely in the sealing washer of seal groove, can reach sealing effect.
