The figure shows: the drill originally on the ground construction was trapped in a big pit (taken by Zou Bin, Shi Liang and trainee Dong Hang) (Chutian Golden Newspaper) reported by Shi Liang and Zou Bin: at about 11:20 yesterday morning, an area of 30x20 meters and depth of 0.5-2 meters ground collapse occurred in the rapid channel project construction site of Baise Second Road on Baise Avenue. This caused the water supply trunk pipe to break but no casualties were incurred. In the afternoon of the same day, Vice Mayor Sun Ya of Wuhan City rushed to the scene with relevant department directors and held an urgent meeting to analyze the cause of the collapse and deal with it. They required that while urgently repairing the water supply trunk pipe, they should also schedule water supply vehicles in time to ensure temporary water use for surrounding residents. After preliminary geological detection, it was determined that this ground collapse was due to the subsidence of the upper sandstone soil layer of the underground cave, which was a geological disaster. The construction unit has quickly deployed measures to prevent secondary disasters from happening. After the accident happened, traffic in Zhangjiawan section of Baise Avenue was completely interrupted, with two-way traffic queuing up like a long dragon. Vehicles going to Wuchang city from the direction of Dongxihu via the third ring road were queued all the way past Baisezhou Bridge from the incident location. Drivers stuck in Hanyang said that the queue exceeded 7 kilometers. The traffic management department quickly implemented temporary traffic control on roads leading to the collapsed section. Traffic entering the city was directed to detour through "Third Ring Road - Jiangcheng Avenue" or Yezhilake Bridge; outgoing traffic was directed to detour through "Xiongchu Street - Yezhilake Bridge - Third Ring Road" via Meijia Mountain and Zhalan Kou. At about 9 p.m., workers still conducting rescue operations on-site told that it would be difficult to restore traffic within a few days. According to the traffic management department, road control will continue until the collapsed road is repaired. During this period, vehicles needing to pass through the collapsed section can choose the aforementioned routes to detour.
