At 7 am on September 9th, under the bridge of Luding County, the town of Town, the temporary construction of the pier, the roar of the machine penetrated through the morning light.

The "September 5" Luding earthquake caused the provincial highway 217 to the west to the asbestos to collapse in multiple places. After several days of emergency rescue, in the early morning of September 9, there were only about 8 kilometers of asbestos in the asbestos. Still being in the middle.

Break through the bottleneck and turn on the "acceleration"! On the Dadu River, a joint emergency rescue kicked off.

Break through the bottleneck

If you can't get in the road, change the water road!

13 kilometers, 2 kilometers, and 11 kilometers ... The Provincial Highway 217 is the main road from Ya'an asbestos to the Eccirus. Tong, in the early morning of the 9th, and the 8 -kilometer section of the road is difficult to open.

The remaining sections are also the hardest "hard bones". Sun Lai, the person in charge of the Shishi Road and Bridge Jianshishi Expressing Department of Sichuan Road and Bridge, who participated in emergency rescue, introduced it. Close to the Dadu River, large machines cannot be transported to the interruption in the middle, and can only be excavated from both ends of the entire highway. With a small job surface, the large number of landslides, the aftershocks continued, and the progress of the rescue construction of the unblocking and unblocked rescue was severely restricted.

To break through the bottleneck, you must open more work surfaces and grab the operation at the same time at multiple points. But how to transport large machines? You know, excavators, loaders, etc. are commonly used machines, all of which are tens of tons of "big guys", and ordinary ships cannot be shipped at all.

Can't get in the road, how about changing the waterway? The front line of the Provincial Department of Transportation's Department of Transportation proposes to carry large tools with power boat bridges! Power boat bridge is a dynamic emergency floating boat. In 2019, the 100 -meter -powered boat bridge was included in the province's highway traffic emergency equipment.

After careful preparation, on the 9th, the Department of Transportation organized the Sichuan Provincial Highway Transportation Emergency Equipment Material Reserve Center and Shu Road Group to open the emergency channel for water and land transportation!

Nationally for the first time

Change the bridge into a boat, transport large tools

The military green transport vehicle drove on the temporary construction of the dock, loading the power of the power boat bridge as an angle, and the power boat bridge slipped into the Dadu River and quickly expanded, becoming a water platform with a length of 10 meters long and 8.3 meters wide. The operator is on the platform and injects fuel in the engine to keep it remained. Immediately afterwards, the driving boat bridge was connected one after another and quickly connected to form a floating boat of 50 meters long.

Luo Qiang, deputy director of the Sichuan Provincial Highway Transportation Emergency Equipment Material Reserve Center, introduced that in the state of quiet water, the 50 -meter -powered boat bridge can load 60 tons to 80 tons. Can carry one or two construction equipment.

"In the past, emergency rescue was to connect the power boat bridge as a bridge, cross the river for vehicles for passing; today, it is the first time that the power boat bridge is used as a mobile ship to transport large construction machinery. This emergency rescue method is the first application in the country. "He said that in order to ensure the safety of transportation, the Dadu River section of the transportation passed in advance was conducted on -site survey to meet the conditions of at least 2.5 meters in water depth and 2.5 meters per second. At the dam, a temporary terminal was built urgently.

At 10 o'clock, after everything was ready, the first excavator drove on the "power mobile ship". Under the command of "Captain" Tan Yi, the boat started! Tan Yi was also the first time. He stood on his head, stared at the river surface, and used the commanders in his hand to make gestures such as progress, slowing down, left, and right.

Be in a hurry

Multi -point homework, more effort

The shipbuilding Dadu River and the downstream of the boat, Sichuan Guan reporters saw that the hillside along the coast was rolling into the river from time to time, splashing water flowers. After the United Village Tunnel, the provincial highway 217 was buried in many places on the shore, and some vehicles were trapped in a break.

At 11:20, after more than an hour of sailing, the first construction machine was sent to the provincial road 217 Jinzhu forest towards the direction of stone cotton, and the temporary landing point across the yellow lawn. This is a slope with a slope of about 30 degrees, which is about 50 meters from the vertical distance from the Provincial Highway 217. Sun Lai told Chuanguan News reporters that in order to ensure that large machines can go ashore, they organized technical personnel to conduct on -site surveys in advance, and identified five landing sites, including Jinzhu Forest, Sesame Du, Songlinping, Zhengjiaping, and Ziya Farm.

As of 18:00 on the same day, the Shu Dao Group was transferred in advance to the 12 large -scale tools that concentrated on the temporary pier, boarded two "power mobile vessels" one by one, and transported to the downstream provincial highway 217 break.Multi -point homework, more effort, grab the "acceleration", are about to start!
