Pre-sealing advanced water stop grouting device for basement roof settlement post-cast strip and construction method
The invention discloses a basement roof settlement post-cast strip pre-sealing advance water stop grouting device which comprises a first-stage waterproof layer, a second-stage waterproof layer and a third-stage waterproof layer, the first-stage waterproof layer comprises a plain concrete reverse ridge (202) and a water stop steel plate (201), and the extending end of the water stop steel plate (201) is provided with an upwards-bent water stop edge used for preventing rainwater from entering the lower portion of a settlement post-cast strip (105); and the second-stage waterproof layer comprises a prefabricated concrete plate (201), a pouring steel pipe (303) and a water stop ring (302). By arranging the two layers of waterproof structures, the waterproof performance of the settlement post-cast strip is effectively improved, meanwhile, due to the integrally-formed plain concrete reverse ridge in the first-stage waterproof layer, construction of a basement top plate concrete layer and the plain concrete reverse ridge is not independently conducted any more, the curing time is shortened, and the working efficiency is improved; and a pouring steel pipe is arranged in the second-stage waterproof layer, so that an effective solution is provided for the pouring construction step of the settlement post-pouring belt in the later period.
本发明公开了一种地下室顶板沉降后浇带预封闭超前止水灌浆装置，包括:一级防水层，包括素混凝土反坎(202)、止水钢板(201)，所述止水钢板(201)的伸出端设有用于防止雨水进入沉降后浇带(105)下方的向上折弯的挡水缘；二级防水层，包括预制混凝土板(201)、浇筑钢管(303)、止水环(302)。通过设置两层防水结构，不仅有效的提高了沉降后浇带的防水性能，与此同时，一级防水层中的一体成型的素混凝土反坎使得地下室顶板混凝土层与素混凝土反坎的施工不在单独进行，减少了养护时间，提高了工作效率；在二级防水层中设置了浇筑钢管，从而保证了后期对沉降后浇带的浇筑施工步骤提供了有效的解决方案。
