The deformation joint part of the top plate has more outstanding leakage problem due to the loss of the protection of the steel bar from the waterproof concrete structure.

However, the arrangement of the deformation joint not only meets the expansion and contraction requirements of buildings, but also generally bears the requirements of uneven settlement and earthquake resistance of the structure, so that the deformation joint still cannot be avoided under a plurality of conditions in the current underground engineering and must be arranged.
At present, the conventional structure of the deformation joint of the top plate comprises an inner joint filling glue, a foam joint filling plate, a buried water stop belt, a foam joint filling plate, an outer joint filling glue, an additional waterproof layer on the upstream face and a flexible waterproof layer from inside to outside, and the construction operation is very complicated. The foam joint filling plate in the structure mainly plays a role in adapting to deformation, and water resistance depends on joint filling glue, a flexible waterproof layer on the upstream face and a buried water stop. At present in actual waterproof application, because the installation of formula waterstop is complicated in the formula of burying, damage or aversion easily in the installation, and there is the lap joint that is difficult to handle, and the interlock effect with the concrete is not good in addition, and its waterproof effect in the seam is difficult to guarantee, and the flexible waterproof layer of seam filling glue and upstream face receives the tensile easy destruction of fatigue that relapse under the effect of subsiding the deformation, and in the deformation joint position water is easy here to converge the afflux seam, so its traditional water-proof effects is general, and the leak rate is high.
