Therefore, the deformation joint of the underground engineering needs to meet the requirements of sealing, water proofing, deformation adaptation, convenient construction and the like. The traditional deformation joint usually adopts a middle-buried rubber water stop or a metal water stop plate, and the construction method of externally sticking the water stop has higher requirements on the construction quality. If the water stop band is not protected sufficiently in the construction process, particularly if the rubber water stop band is damaged, the water stop band is not fully welded or the water stop band is not tightly integrated with concrete, the deformation joint waterproof structure can lose the proper efficacy, and water leakage occurs at the position. Once the settlement joint of the underground engineering leaks water, the repair and maintenance cost in the later period is extremely high, and the settlement is difficult. Therefore, it is necessary to develop a waterproof structure for deformation joints of underground engineering with multiple functions of water stopping, rapid plugging, drainage and the like.
