Contractor DCT Civil Engineering is putting the final touches to a 14,100m3 storm water storage tank designed by consultant GHA Livigunn for client United Utilities.
The 25m diameter, 34m deep tank in north eastern Liverpool will hold a mixture of storm and wastewater during periods of high rainfall, and then gradually release it back to the sewer network when capacity is available.This will allow it to remove 79 properties from the flood register.
The tank features a central flushing column that will be used to clear blockages.The project is due for completion in March, six months early.
利物浦修建的蓄水池，直径25米，基坑深度达到了34米，相当于十层楼高。总容量约14,100立方米。用来缓冲城市暴雨的威胁，同时与市政管网相连，当超过水池负载能力时通过排水管道予以释放。
这个巨大基坑中的混凝土圆柱，用来清淤。
34米深的巨大基坑，无水的时候会不会飘起来。印象中最大的人为开挖的基坑当属南非金伯利钻石矿，深度达到了1097米。
