Description

The leading sealing of a kind of sole plate ater-casting
Technical field
The utility model relates to the leading sealing of a kind of sole plate ater-casting, belongs to technical field of building construction.
Background technology
In recent years, along with the development of construction technology, the engineering of high level, superelevation layer, the big scale of construction is more and more, and the application of ater-casting frequently occurs thereupon.The ater-casting generally can be divided into flexible ater-casting and pouring after settlement by purposes.No matter flexible ater-casting, or pouring after settlement, its retention time is all longer.When the building foundation is positioned at groundwater table when following, adopt traditional ater-casting to stay the mode of establishing, the ater-casting must be built the ater-casting concrete again after main structure construction is finished.This just requires to continue to carry out precipitation, guarantees that groundwater table remains on below the basis, after the ater-casting concrete is finished and built to agent structure, just can stop precipitation.When the building main body construction time is longer, will certainly increase the precipitation expense greatly, increase engineering cost; Foundation Design is exposed to outdoor for a long time, because day and night temperature is bigger, basic exterior wall easily produces flexible crack; After finish on the basis, do not carry out backfill immediately and have potential safety hazard for deep-foundation pit engineering; Simultaneously, not backfill of basic earthwork, the construction with follow-up other operations of influence influences the duration of a project.
The utility model content
The technical problems to be solved in the utility model is: overcome traditional ater-casting precipitation expense height, exterior wall easily produces crack, deep foundation ditch potential safety hazard and influences problems such as duration of a project.Providing a kind of can carry out leading sealing to underground water, can carry out follow-up works such as external wall waterproof, backfill after finish on the basis, can stop the leading sealing of the sole plate ater-casting of precipitation at any time according to requirement of engineering.
The technical scheme that its technical problem that solves the utility model adopts is: the leading sealing of this a kind of sole plate ater-casting, comprise sole plate, the ater-casting that in sole plate, is provided with, fast easy-to-closing net and water-swellable sealing rod are installed in the side, ater-casting, it is characterized in that:
A, below sole plate post-poured strip, increase together leading sealing base plate;
The shrinkage joint is stayed at b, leading sealing base plate middle part one, adopts extruded polystyrene board to fill in the seam;
C, at one rubber fastening band of shrinkage joint intermediate lateral setting;
Reserve the cleaning layer between d, sole plate post-poured strip and the leading sealing base plate;
E, sole plate post-poured strip side adopt the fast easy-to-closing net to install template, and leading sealing base plate and sole plate be concreting simultaneously;
F, leading sealing backplane double steel bar.
In project subject construction period, this leading sealing base plate both can waterproof, can freely stretch again, did not influence follow-up works such as basic earthwork backfill; Because sole plate post-poured strip is easy to clean not, between sole plate and leading sealing base plate, increase the cleaning layer.
Compared with prior art, the beneficial effect that the utility model had is: the foundation pit dewatering time has been shortened in the leading sealing of sole plate ater-casting, reduces operating expenses.Basic external wall waterproof, outdoor backfilling of earthwork can in time be carried out in this ater-casting after Foundation Design is finished, reduce the probability that produces structural cracks because of day and night temperature between the basement exposure period.Simultaneously, in time carry out backfilling of earthwork after, can carry out the construction of subsequent handlings such as masonry, more reasonably carry out operation and intert, the reduction of erection time.Carry out external wall waterproof, backfilling of earthwork operation after finish on the basis immediately, eliminated the potential safety hazard that deep foundation ditch brings.The timely backfill of foundation ditch has increased the construction plant of main body construction, for civilized construction has been created better condition.This ater-casting precipitation time shortens greatly, and pump-out reduces greatly, has protected water resource effectively.
