The utility model discloses an efficient water circulation system for mud suction and subsidence of caisson, which comprises a dumping site, a secondary sedimentation tank, a mud transfer tank, a water recycling recovery tank and a caisson hole connected in turn from high to low. A caisson annular water channel is also connected between the water recycling recovery tank and the caisson hole, and the caisson annular water channel is arranged around the caisson hole, and the dumping site is also sucked through the caisson hole. The mud machine is connected with the caisson hole to form a circulating system. The system adopts the principle of \from high to low\ from the abandonment site to the caisson hole, fully utilizing the advantages of terrain to recycle the construction water, eliminating the power consumption caused by insufficient water supply capacity; the organic combination of multiple reservoirs can effectively precipitate sediment, alleviate the wear and tear of water supply equipment, and overcome the low efficiency, high energy consumption and inappropriate replenishment of water by traditional pumps. The system can be used to solve the problems of inadequate utilization of water resources and waste of energy in large-scale caissons.

一种沉井吸泥下沉高效水循环系统
本技术属于施工
,具体涉及一种沉井吸泥下沉高效水循环系统。
技术介绍
沉井基础是桥梁基础施工中重要的结构物。大型沉井基础吸泥下沉施工中吸泥量巨大,可达到数十万方以上。伴随吸泥的排出,需要向井孔内补给大量水,以保证沉井内外平衡。常规施工时,往往在周围水源处通过水泵抽水补给至沉井内,确保沉井水量充足。在大型沉井吸泥下沉施工中,吸泥量巨大,所需水量更是吸泥总量的数倍。采用水泵抽水补给施工用水,能耗高,耗时、耗力、效率低下,加大成本投入。
技术实现思路
针对上述技术问题,本技术的目的在于提供一种沉井吸泥下沉高效水循环系统,为大型沉井基础吸泥下沉快速高效补充水资源,提高水资源利用率,节约成本,降低能耗,进一步提高下沉效率。本技术的技术方案具体如下:一种沉井吸泥下沉高效水循环系统,包括由高到低并依次连接的弃土场、二级沉淀池、泥浆中转池、水循环回收池和沉井井孔,在水循环回收池和沉井井孔之间还连接有沉井环形水沟,所述沉井环形水沟围绕沉井井孔外周布设,所述弃土场还通过吸泥机与沉井井孔相连,从而构成一个循环系统。本技术的水循环系统采用由高至低的原则,连接弃土场回水端和后续各沉井蓄水池的水沟,从而保证完全利用地势优势将施工用水进行回流再利用,消除因供水能力不足而导致的电能消耗。本技术在沉井井孔外周布设沉井环形水沟,不排水施工时,水循环系统回收池与环形水沟连通组成连通器,确保环形水沟水量供给。环形水沟布置在沉井四周,使水体均匀集中分布在沉井周边,可实时为沉井各个井孔同时供水,有效缩短供水距离、线缆长度,方便操作,提高供水效率。进一步地,上述沉井吸泥下 ...
