China Infrastructure News (reported by Xu Yinghua and Niu Zhipeng).At 23:59 on December 18, 6Level 2**, the depth of the epicenter is 10 kilometers, as of the evening of the 20th, ** caused 113 people in Gansu, 22 people in Qinghai, 12 people missing, and some water, electricity, transportation, communications and other infrastructure damaged.
* Caused a local sand surge in Jintian Village and Caotan Village, Zhongchuan Township, Haidong Township, Qinghai Province, 20 kilometers away from the epicenter, affecting the houses and roads in the village, and many people were buried due to secondary disasters after the earthquake.
On the 21st, China Aneng No. 2 Bureau invested 100 people and 54 sets of equipment to search and rescue the missing people in the area of No. 3, No. 4 and No. 5 points in Caotan Village, and carried out excavation and dredging and access roads.
The emergence of the sand surge and the local natural environment have brought great difficulties to the rescue, the sand surge has caused a very thick silt, the road is impassable, and most of the houses in Caotan Village are buried by silt, and the height of the silt is mostly 3 to 4 meters. The sludge is heavy and dense, and can only be removed by heavy machinery. Due to the unstable state of the "sand surge", when the temperature rises during the day, the "sand surge" will melt and become soft, and it is often the case that the surrounding silt is quickly backfilled soon after the excavator excavates, and the excavation is very difficult. When the temperature drops below zero at night, the "sand swell" will freeze and harden, which will also have a certain impact on the excavation.
According to the situation at the scene, they adopted the tactics of "excavation along the way, extension of the surface by the point, and grid search" to peel off the track cover layer, and carried out search and rescue of the missing personnel of the debris fluid and grabbed the passage road, especially for the fact that the No. 3 rescue point has a narrow passage, unfavorable traffic, inconvenient access to large machinery, and limited stockpile space in the stockyard. At 0:00 on the 21st, the main road of the No. 3 rescue point was successfully opened, and the phased node goal of rescue was achieved.
The weather at the rescue site was cold, aftershocks continued, the lowest temperature reached minus 16 degrees on the night of the 20th, and at 4:02 on the 21st, another 4 occurred in Jishishan County, GansuAftershocks of magnitude 1. The rescue personnel work in two shifts, and people work day and night 24 hours a day. The rescue team members said that it is still 72 hours of rescue time, and as long as there is a glimmer of hope, they will do their best. As of 15 o'clock on the 21st, a total of 4 missing people have been searched, 29,180 cubic meters of silt have been excavated, 120 meters of emergency construction roads have been built, and 100 cubic meters of stone have been filled.
