Anti-streaming flexible water bag system for diaphragm wall joint and construction method
The invention discloses an underground diaphragm wall joint anti-streaming flexible water bag system and a construction method. The system comprises a flexible water bag, a top and bottom opening sealing structure, a flexible water bag protection structure, a water pump, a flow meter, a pressure gauge and a control cabinet; a flexible water bag with a sealed top opening and a sealed bottom opening is fixed to the outer side of a steel plate at an underground diaphragm wall joint, the flexible water bag is synchronously installed along with a reinforcement cage, before concrete is poured, water is synchronously injected into the flexible water bag through a booster pump, meanwhile, the injected water amount and water pressure are monitored through a flow meter and a pressure meter, and the water injection stopping time is controlled through the water amount index and the pressure index; before the rear row width concrete is poured, water in the flexible water bag is pumped out, and the pumped water can be reused. The water injection flexible water bag is adopted to cut off a concrete streaming path, the synchronous water injection system can ensure that the load of the flexible water bag on the diaphragm wall joint is uniformly changed, the reinforcement cage is always located in the center of the groove section, water in the flexible water bag can be repeatedly used, the engineering quality can be effectively improved, and wide application prospects are achieved.
本发明公开了一种地连墙接头防绕流柔性水囊系统及施工方法，其系统包括柔性水囊、顶底口密封结构、柔性水囊保护结构、水泵、流量计、压力表以及控制柜；将顶底口密封的柔性水囊固定于地连墙接头处钢板外侧，柔性水囊随钢筋笼同步安装，在混凝土浇筑前，利用增压泵同步向柔性水囊内注水，同时利用流量计、压力表监测注入水量及水压，采用水量、压力两个指标控制停止注水时机；后行幅混凝土浇筑前，将柔性水囊内的水抽出，抽出的水可重复利用。采用注水柔性水囊隔断了混凝土绕流路径，同步注水系统可保证柔性水囊对地连墙接头的荷载均匀变化，确保钢筋笼始终处于槽段中央，柔性水囊中的水可重复使用，可有效提高工程质量，具有广阔的应用前景。
