The mountains are surrounded by clouds and mists, and the river water is rushing. In Luding County, Ganzi Prefecture, Sichuan Province, production and life in the small valley town that experienced the pain of the earthquake have gradually returned to normal, but the rescue and relief work after the earthquake is still in full swing.

On September 28, the emergency rescue after the "9.5" Luding earthquake ushered in a new node: with the emergency passage of provincial highway 217 Zhengjiaping to Lianhe Village tunnel section, Lianhe Village tunnel to Wandong Village, Wang The production and living channels from Gangping Township to Fawang Village were opened simultaneously, and all the national and provincial trunk roads, county and township highway emergency channels blocked by the earthquake were fully opened. At present, in order to ensure safety, traffic control has been implemented to rush the passage of the road section.
Rescue the emergency passage in time after the earthquake, which can meet the needs of emergency transportation, assist the search and rescue of casualties, and is also of decisive significance for the follow-up post-disaster resettlement and reconstruction. Affected by the earthquake, many national and provincial trunk roads, county and township roads were blocked at the epicenter, especially the entire section of the S217 provincial road from Luding to Shimian collapsed. The length of road interruption was 59 kilometers, of which 19 kilometers were required to focus on the road.

The interruption of the road has made it difficult for rescuers and materials to enter the affected area of the epicenter, and it is imminent to unblock the "channel of life"!
In order to quickly transport large-scale machinery and equipment to the key points of road rush, under the unified deployment of Sichuan Provincial Department of Transportation , Sichuan Provincial Highway Traffic Emergency Equipment and Materials Reserve Center and Shudao Group jointly carried out emergency rescue, rush to build temporary Wharf, open the emergency channel for water and land combined transportation, and put in 16 powered boat bridges to spliced together to form a powered ship carrying equipment.
"A power boat is made up of 4 power boat bridges, which can carry 80 tons. This means that a power boat can carry two large excavators and four or five small mechanical equipment." Zhou Yongjun, member of the party committee and deputy general manager of Jianjian Group, introduced that these machinery and equipment were transported by water to five landing points in Jinzhulin, Zhizhituo, Songlinping, Zhengjiaping, and Ziyachang, and then successively transferred to the lower reaches of Dadu River. 28 disaster-affected points.
raced against time to speed up transportation equipment to ensure smooth access, while scientifically planning "wall chart operations". In the process of rushing through, the rescue commandos used satellite remote sensing, drones and other equipment to find out the blocking points and landslide collapse points in advance, and made a scientific prediction of the difficulties in the rescue. The empowerment of these high-tech technologies will “speed up” the road section as soon as possible.
"But even so, the commandos still encountered many difficulties in the process of the emergency road being unblocked." Li Lin, member of the Party Committee and Chief Engineer of the Highway Bureau of the Sichuan Provincial Department of Transportation, revealed, "The emergency road rescue after the earthquake lasted 24 days. In addition to the Wenchuan earthquake, it took us the longest time to rush through the national trunk highway in the process of earthquake relief in recent years. The earthquake caused extremely serious damage to local road traffic, and the aftershocks caused continuous collapse of high slopes and a large number of slides. The sediment and soil and stone have become the biggest difficulty encountered in rushing through."

Li Lin also said, "Taking the 19-kilometer section of the S217 provincial highway from Luding to Shimian as an example, the road to the subgrade is almost completely damaged, and there are more than 20 landslide points along the route. These points are located on the back of the mountain. There are steep cliffs on one side and the Dadu River with turbulent water on the other side. High-level landslide points have been formed along the rescue line due to earthquakes. Due to the influence of wind and precipitation, landslides and landslides have occurred repeatedly."
Ren Junjie participated in this event. A long-arm excavator driver in the rescue work, according to him, in the rescue project, they faced difficulties they had never encountered before, "The road was just cleared, and it didn't take long for the gravel to come in again. , the excavator operation is very dangerous." He said that in the process of rushing through the operation, every excavator operator was fully focused, and observation posts were set up on the river and at high places, and it was necessary to pay attention to the rockfall situation at all times to ensure the safety of the excavation work," said To be honest, there must be feelings of fear, but at the critical moment, we must face the difficulties."
"According to statistics, we have invested more than 6,500 people to participate in road rescue, and 224.3 kilometers of roads (including village roads) have been rescued.There, more than 348 blocked points were cleared. Li Lin said that all the emergency passages along the Luding-Asbestos section of provincial highway S217 have been opened up, and the rush to open the main passages affected by the "9.5" Luding earthquake has been basically completed, which is for the follow-up emergency supplies and personnel to enter the epicenter and participate in local reconstruction. Created the premise. (Guo Ying)
