Workers at a construction site in Zhengzhou were buried by landslides. What rescue measures did the emergency department take?

Workers at a construction site in Zhengzhou were buried by landslides. What rescue measures did the emergency department take? Let's discuss this problem below, hoping that these contents can help friends in need.

65438+1At dusk on October 23rd, a construction site in Guancheng District of Zhengzhou City collapsed and some workers were buried. On the 24th, the staff of the local emergency management bureau told the reporter that emergency repair work had been carried out at the time of the accident, which resulted in two deaths and one injury. At this stage, the health status of the wounded is stable.

65438+1On October 24th, some fans reported that on the evening of 23rd, a construction site in Guancheng District of Zhengzhou City collapsed and some staff members were buried. The reporter saw from the photos and short videos of the online explosion that it had just snowed in Zhengzhou that day, an excavator stopped at the scene of the accident, and many local fire safety and emergency units were carrying out rescue.

At noon on the 24th, the reporter learned from the emergency management bureau of Guancheng District, Zhengzhou City that the accident occurred at around 6 noon on the 23rd, and electric power repair work had been carried out at the scene at the time of the accident. A staff member of our bureau said that the accident caused two deaths and one injury, and the health status of the wounded was stable at this stage. The city's second-level leading cadres attach great importance to this matter and have set up an accident investigation team to intervene in the investigation.

Collapse accident, as one of the five common accidents in engineering construction, refers to the accident that an object exceeds its yield limit or is destroyed due to structural reliability damage under the action of external force or external force.

Collapse accidents during construction mainly include: unbalanced formwork support system of precast concrete beam and slab, earthwork collapse caused by unbalanced slope of foundation pit, collapse during project demolition, collapse of crane and other lifting machinery, and poor quality of courtyard walls and roofs of projects under construction.

In the whole construction process, the following aspects should be paid attention to:

(1) In the underground workflow such as slope, foundation pit and digging pile, the information construction method should be selected for the excavation of foundation pit and the construction of supporting structure of earthwork, and the enterprise should choose the dynamic design scheme method, and adjust the construction method and risk prevention countermeasures in time according to the specific situation.

(2) The construction site shall plan the temporary drainage equipment in the construction area as a whole, and the temporary drainage pipeline shall not damage the excavated and backfilled slope.

(3) When excavating in areas with complex terrain and geological environment, which are prone to landslides and collapses, the drainage pipeline scheme should be defined.

(4) When the surface water around the site is collected and discharged or the surface water pipeline leaks, countermeasures should be taken to block, drain the pipeline and be hydrophilic, and safeguard measures should be taken to solve the foundation pit problem.

(5) When the excavation of foundation pit is less than that of foundation pit and pile hole with groundwater, effective dewatering measures should be taken to reduce groundwater and determine the key construction scheme for dewatering.

(6) The raw materials on site should not be piled up at the edge of foundation pit, top of slope and pile hole. When stacking is needed, the total weight and spacing of stacking should meet the design requirements.

(7) The distance between all kinds of construction machinery and equipment and the edge of foundation pit, slope top and pile hole shall be determined according to the net weight of machinery and equipment, supporting structure and soil layer, and shall not be less than1.5m..

(8) Excavation and support shall be carried out according to the order and main parameters required by the foundation pit construction design, and excavation shall be carried out in layers, sections, limited and balanced.

(9) Of course, the slope ratio of foundation pit with slope should meet the design requirements and the requirements of current national standard "Technical Specification for Safety of Earthwork in Building Construction" JJ180.

(10) During foundation pit construction, weather forecast data shall be collected. In case of long precipitation time and heavy rainfall, covering measures should be taken in advance for the excavated unsupported foundation pit outer wall, and the accumulated water in the foundation pit should be eliminated immediately.

(1 1) In the process of foundation pit excavation, support and pit operation, the inspection shall be carried out according to the current national industry standard "Technical Specification for Monitoring of Building Foundation Pit Engineering" GB50497, and the foundation pit and its surrounding environment shall be inspected on time. If any abnormality is found, certain effective measures shall be taken immediately.
