Yesterday, the concrete squeezed the air in the pouring area, causing the road surface to be jacked up.

    At about 8:20 a.m. yesterday, the road surface 500 meters west of Huixin East Bridge in Beijing suddenly arched. At 10 a.m., the arched road surface had expanded to two lanes wide. Traffic police quickly imposed restrictions on the section.

    It was determined that the underground excavation area of Metro Line 5 was below the section. At 4 a.m. yesterday, the construction site filled concrete into the pipe shed studio of the underground excavation section. As the concrete squeezed the air in the pouring part, the air jacked up the road surface. At 12:50 p.m., the excavator arrived at the scene for rush repairs. It was not until 9:00 p.m. last night that the rush repairs were all over.

    It is understood that the patrol police first discovered the protuberance of the road surface at 9 o'clock. 30, the protrusion of the road surface became more and more obvious.

    At 11:10, it can be seen at the scene that the ground was surrounded by construction signs, and about 20 road workers were shoveling soil from the pit dug by a small excavator with shovels. Several traffic policemen were maintaining order, and their uniforms were soaked with sweat.

    Zheng Shifu, a driver who was blocked, said with a wry smile, "I've been blocked for two hours. I can only move step by step. I really have no temper. Wait slowly." Other drivers interviewed waved their hands or shrugged their shoulders to show their helplessness.

    Temporary road closure, additional police force to ensure construction.

    It is understood that the accident occurred near the construction site of Metro Line 5. After the accident, the responsible persons of the Traffic Management Bureau, Gonglian Company and the relevant units of Metro Line 5 rushed to the scene immediately. Because the cause of the accident was not clear and it was feared that the rupture of the gas pipeline or water pipe would cause a greater impact, each unit temporarily formulated two sets of emergency repair plans: first dig the big bag, if the situation is not serious, lay the steel plate; if the situation is serious, leave the construction at night. After the emergency repair plan is formulated, the emergency repair work will begin immediately. At the same time, the traffic control department closed the two lanes in the middle and sent more police to ensure the smooth progress of the construction.

    00 yesterday, the rush repair work was still in progress. It is understood that the progress of rush repairs depends on the situation on the spot, and it is expected that the road surface may return to normal today.
