Basement deformation joint structure and construction method

The invention relates to the technical field of basement deformation joints, in particular to a basement deformation joint structure which comprises two foundation structural parts, a water stop belt, a covering plate and a water absorption assembly, a deformation joint is formed between the two foundation structural parts, and the water stop belt is arranged in the deformation joint and fixed to the two foundation structural parts; the covering plate covers the top opening of the deformation joint, the water absorption assembly comprises a box body and a water absorption sponge, the box body is fixed to the upper surface of the water stop belt, the water absorption sponge is arranged in the box body, and water inlets are formed in the two sides of the box body; the basement deformation joint has the advantage that the situation that underground water or rainwater enters the basement through the deformation joint is reduced. 本申请涉及地下室变形缝技术领域，尤其是一种地下室变形缝结构，其包括两个基础结构件、止水带、覆盖板以及吸水组件，两个所述基础结构件之间形成变形缝，所述止水带内置于所述变形缝
