Waterproof rubber pad for large shield construction

The utility model relates to the technical field of shield construction sealing, in particular to a waterproof rubber pad for large shield construction. Comprising a springback part and a supporting part, the elastic deformation capacity of the springback part is greater than that of the supporting part; the supporting part is embedded in the springback part, and supporting force opposite to external force is formed in the springback part in the process that the springback part is extruded by the external force. According to the waterproof rubber pad, the layered structure is formed in the waterproof rubber pad, the waterproof rubber pad can have the large deformation capacity and the good internal supporting capacity at the same time according to the different elastic deformation capacities of the layered structure, and the waterproof sealing effect of the waterproof rubber pad is improved. 本实用新型涉及盾构施工密封技术领域，尤其涉及一种用于大盾构施工的防水橡胶垫。包括：回弹部和支撑部；所述回弹部的弹性形变能力大于支撑部的弹性形变能力；所述支撑部嵌套在回弹部中，并在外力挤压回弹部的过程中在回弹部的内部形成与外力相反的支撑力。
