Advanced sealing structure for basement top slab settlement post-cast strips

The invention relates to the technical field of buildings, in particular to an advanced sealing structure for basement top slab settlement post-cast strips. The advanced sealing structure for the basement top slab settlement post-cast strips is characterized in that sealing cover plates are tightly attached to the upper portions of post-cast strip spaces; the width of the sealing cover plates is 400 mm larger than that of the post-cast strip spaces; multiple cover plates are bonded and sealed through polymer mortar to form the basement top slab settlement post-cast strips; one observing opening and one entering opening are formed in the position of the corresponding cover plate in the middle of each post-cast strip or two observing openings and two entering openings are formed in the positions of the cover plates at the two ends of each post-cast strip; the observing openings are used for observing whether pouring of self compact concrete is finished or not; the entering openings are used for pouring the self compact concrete. The above steps are carried out in advance; when the designing demand is met and sealing is achieved after main body settlement is stabilized at the later stage, pouring is carried out through a concrete pump by means of self compact concrete, and self compacting is achieved without vibration; therefore, advanced sealing for the settlement post-cast strips is achieved and the designing demand is met.
