Pit water blocking structure in sand-gravel foundation pit and construction method of pit water blocking structure
The invention discloses a gravel ground foundation pit-in-pit water blocking structure and a construction method thereof.The gravel ground foundation pit-in-pit water blocking structure comprises a prefabricated caisson, the prefabricated caisson is arranged in a pit-in-pit of a foundation pit, a box opening of the prefabricated caisson is higher than the underground water level in the foundation pit, a gap is formed between the prefabricated caisson and the side wall of the pit-in-pit, and the prefabricated caisson is arranged in the pit-in-pit of the foundation pit; a plurality of anchoring parts are connected to the outer side of the prefabricated caisson; concrete is poured in the gaps, and the concrete wraps the multiple anchoring parts so that the concrete can be solidified to form the anti-floating ring stone; the brick forming die shell is built in the prefabricated caisson, the side wall of the brick forming die shell obliquely extends upwards and outwards to the pit bottom of the deep foundation pit, and a backfilling groove is formed between the side wall of the brick forming die shell and the side wall of the pit-in-pit; and the backfill groove is filled with the backfill material. The problems of high construction cost and long construction period of pit-in-pit construction in the existing gravel foundation pit are solved.
本发明公开了一种砂石地基坑中坑阻水结构及其施工方法，包括：预制沉箱，设置于基坑的坑中坑中，所述预制沉箱的箱口高于所述基坑内的地下水水位，所述预制沉箱与所述坑中坑的侧壁之间形成有间隙，所述预制沉箱的外侧连接有多个锚固件；抗浮环石，所述间隙中浇筑有混凝土，所述混凝土包覆于多个所述锚固件以固结形成所述抗浮环石；砖胎膜模壳，砌筑于所述预制沉箱内，所述砖胎膜模壳的侧壁斜向上向外延伸至所述深基坑的坑底，所述砖胎膜模壳的侧壁与所述坑中坑的侧壁之间形成有回填槽；回填料，填充于所述回填槽中。本发明解决了现有的砂石地基基坑内的坑中坑施工，施工成本高和工期长的问题。
