Construction method for sealing post-cast strip in advance
The invention discloses a construction method for sealing a post-cast strip in advance, and relates to the technical field of post-cast strip sealing, the construction method comprises blind ditch excavation and water-collecting well arrangement, the blind ditch excavation comprises the following five steps of site leveling, surveying and lofting, groove excavation, blind ditch backfilling and acceptance inspection, and the water-collecting well arrangement principle is that each blind ditch is communicated with two water-collecting wells; the water-collecting well is arranged on the outer side of the basement outer wall, the water level observation point position is marked in the water-collecting well, the water-collecting well is built by a simple brick wall, the height of the water-collecting well is from the pit bottom to the basement top, a reinforcing support is arranged in the water-collecting well, the elevation of the bottom of the water-collecting well is 100mm lower than that of the blind ditch, the inner diameter of the water-collecting well is not smaller than 800mm, and a water pump is arranged in the water-collecting well. According to the method, the anti-floating problem of the basement is perfectly solved through the water collecting well arranged between the basement and the outer wall and the blind ditch arranged below the post-cast strip, and the post-cast strip is sealed in advance within one month before the top sealing of the main body, so that the influence on the waterproof and backfilling construction process is reduced, the construction organization is optimized, and the potential safety hazard in the construction engineering is reduced.
本发明公开了一种后浇带提前封闭施工方法，涉及到后浇带封闭技术领域，包括盲沟开挖和集水井布置，盲沟开挖包括以下五个步骤：平整场地、测量放样、沟槽开挖、盲沟回填和验收，集水井布设原则包括：每条盲沟连通两个集水井，集水井位置设置在地库外墙外侧，集水井内标注水位观测点位置，集水井由简易砖墙砌筑，集水井高度为从坑底至地库顶，集水井内置加固支撑，集水井井底标高低于盲沟100mm，集水井内径尺寸不小于800mm，集水井内置水泵。本发明通过在地库和外墙间布设的集水井以及后浇带下布设的盲沟完美解决了地下室抗浮问题，在主体封顶前一个月内完成后浇带的提前封闭，从而减少对防水及回填土施工进程的影响，优化了施工组织，减少了施工工程中的安全隐患。
