Shield tunnel elastic sealing gasket "dual-waterproof" water-tightness inspection device

The invention discloses a shield tunnel elastic sealing gasket "dual-waterproof" water-tightness inspection device. The inspection device comprises one rigid ribbed plate and four rigid flat plates. The rigid ribbed plate is composed of a main plate and two pairs of rib plates. The two pairs of the rib plates are symmetrically arranged at the two sides of the waist parts of the main plate respectively. The shield tunnel elastic sealing gasket "dual-waterproof" water-tightness inspection device is used so that limitation that only penetration performance of the contact surface of an elastic sealing gasket and a steel molding plate is inspected in the existing test methods is extended, experimental study work on penetration performance of the contact surface of the elastic sealing gasket and concrete can be carried out, and waterproof performance of using a dual-waterproof sealing gasket structure in the project can be accurately simulated. Besides, the inspection device can be matched with the widely used common concrete anti-permeability instruments at present so that processing cost is reduced.
