Carry out work related to site selection for post-disaster recovery and reconstruction. Reporter Ye Wenjuan Photo by reporter Ye Wenjuan.
26 groups, 178 people, 279 geological hazard points, completed engineering geological surveying and mapping 746 square kilometers, 79 exploration wells were dug, and comprehensive means were used to provide planning and site selection ...... for post-disaster reconstruction and resettlement sitesThese numbers are 6After the occurrence of Level 2**, the main work records of the Qinghai Provincial Environmental Geological Survey Bureau in Zhaizi Village, Guanting Town, Haidong Citizen and Hui Tu Autonomous County.
With the arrival of spring and the melting of spring water, in order to prevent the occurrence of secondary disasters, on February 13, the staff of the Engineering Geological Environment Investigation Branch and the Geological Disaster Restoration Branch of the Qinghai Provincial Environmental Geological Survey Bureau gave up their holidays and rested, and went to Zhaizi Village, Guanting Town, Caotan Village, Zhongchuan Township and other places to carry out re-investigation of geological hazards, as well as site selection and other related work for post-disaster recovery and reconstruction projects.
Zhaizi Village, Guanting Town, is located at the front edge of the Yellow River terrace, and the ridge of Zhaizi Mountain near the village showed signs of deformation, and some areas collapsed. "The slope direction is 170 degrees, and the slope is relatively upright......The staff reported the inspection to Deng Xiaofei, vice president of the Geological Disaster Restoration Branch of the Qinghai Provincial Environmental Geological Survey Bureau, who was commanding at the scene.
This is our fourth round of investigation, we are now in a small landslide, at present, from the landslide location can be seen that after the landslide occurred on the landslide site, the impact of trees and slopes, canals, and people's houses is still relatively large. Deng Xiaofei introduced.
The reporter saw at the scene that the landslide caused by ** caused the mud and rocks on the mountain to reach nearby residences. "This investigation mainly depends on whether this part of the area has been deformed again in the later stage. During the investigation, it was also found that some springs and a deformation of the entire collapse site and landslide site were basically in a stable state. Deng Xiaofei said.
It is understood that after the occurrence of the first disaster, the Qinghai Provincial Department of Natural Resources and the Qinghai Provincial Environmental Geological Survey Bureau organized technical forces to investigate the hidden dangers of secondary geological disasters after the disaster, and do a good job in geological disaster rescue and relief, emergency investigation, hidden danger investigation and other technical support work.
The scope of the investigation includes geological disaster sites, as well as schools, hospitals, and temporary resettlement sites for the affected people. After investigation, on the basis of the original more than 200 geological hazards, more than 30 new geological disaster points have been added. Deng Xiaofei said.
Ground disaster investigation and site selection survey were carried out simultaneously to lay a good foundation for rebuilding homes.
In Zhongchuan Township, Minhe County, the staff is holding relevant instruments and equipment to conduct engineering geological survey of this area. With the shouts of "knock, knock, knock" from the staff, the investigation work was carried out in an orderly ......manner
What I just did is the best surface wave exploration method, which can find out our stratigraphic structure, and can also find out the wave velocity of different strata, which can provide a basis for the evaluation of the engineering geological site grade of our site in the future. Gan Bin, vice president of the Engineering Geology and Environmental Survey Branch of the Qinghai Provincial Environmental Geological Exploration Bureau, told reporters.
According to the reporter's understanding, in the site selection and survey work, the staff identified the on-site topography, geological structure, stratigraphic structure, geological age and other conditions, and divided a detailed engineering geological unit. At the same time, suggestions for the prevention and control of the potential impact of the planned construction project were put forward, and a comprehensive evaluation of the site stability and engineering construction suitability of the planning area was carried out.
Gan Bin told reporters that this work is mainly carried out in three aspects: ground investigation, drilling, and engineering geophysical prospecting, mainly looking at the topography of the site, revealing the lithology of the formation, and then taking relevant samples to be sent to the laboratory for testing.
