Early morning of August 14, map Wenchuan County lying within the heavy rain caused road damage across the board are subject to different tolls. According to Provincial Highway 303 Yingxiu to Wolong large front torrential debris flow emergency rescue headquarters survey lying along the road mapped landslides 11, 250 Articles, roadbed damaged about 6.2 km, about 3 km damaged roads, damaged bridges 6 , Block 1 tunnel, shed tunnel 300 meters, 16 culverts, protection 8.5 Articles, ditch 10 km, forming lake 3.
The disaster that day, lying road map project owner Revive Sichuan Sichuan Highway Construction Development Co., who quickly organized to repair the road. 17 days, the Highway 303 road map into horizontal reopened more than 260 staff, 40 sets of machinery, including excavators 11 sets, 12 loaders, bulldozers, 2 sets of 6 sets of dump truck, air compressor, 2 sets 10 sets of emergency rescue vehicles and two directions from the Wolong Yingxiu and equipment and teams also organized "attack from both sides" to reopened. 31 reopened the emergency rescue channel, the pavement steep slope, the curves are sharp, narrow embankment, safe passage of vehicles does not have the ability to present only emergency vehicles and survey design engineering personnel.
Hard to imagine eating the way open "Panda Road"
Fighting in the Provincial Road 303 lying on the road map as long as 17 days, workers finally a delicious meal. The morning of August 31, Provincial Road 303 across the board Yingxiu to Wolong section reopened.

Reopened a little diversion, "the devil road"
August 31, drove off from the Yingxiu just reopened the reflected through the horizontal road. Some sections of the retaining wall had been covered with green were destroyed, the main tunnel completed in South China has been more than two months the body was buried in debris flow deposits. Road on the left, the broken mountain seems to be washed down at any time; road on the right, the original pavement several flooded about 2-3 meters deep.
Sichuan Road & Bridge Tunnel general manager Xiao Zhiming introduced the map lying 54 km length of road, in the debris flow, from the Town in Wenchuan County to more than 20 km Gengda rural roads damaged. Landslides along the 11, the total over 2.5 million cubic meters, the formation of lake 3, damaged embankment about 6.2 km. The road has been reopened at the front of the bench road map of Sichuan Road & Bridge Section Manager yw2 contract Changqing Yi, said the road after the earthquake secondary disasters and large-scale, affected by the floods, the collapse of the mountain easily broken.
After the disaster, lying road mapping project owner in Sichuan Xing Shu company quickly activate contingency plans. August 15, the exploration teams of design experts, more than 20 km on foot the next day reached into Geng, field reconnaissance disaster, gathering technical information, emergency access roads for the construction of the development program to provide reliable and detailed technical parameters.
Yingxiu starting from the direction to reach about 5 km Geng, construction workers were called "devil road." Monument at the Qiu Guanghua, a height of about 5 meters of debris accumulation body completely buried the road. Xing Yuan Quan Shu chief engineer described: "debris flow high water content, it is easy to fall into cars. With narrow roads, the machine shop is not open. We have a rock in the accumulation of body pads, digging machines go first to a station, and 1 station in behind the rolling road, loader then, little by little to ease road pressure. "
Come to the stage one kilometer farther section of road was the boulder tumbled down the mountain heap buried, formed after the earthquake the sidewalk into the main river channel. After investigation and discussion, the newly built sidewalk across from the rock pile. Yuan Quan said: "The first put a small gun, shattering the stone a little, then dig up the stone excavator. To continue blasting, and then dig up the stone. This diversion of little by little."
Lying road repair map, the difficulties facing not only rock. There is a road, lake to form a gap between the lake and the road up to 30 meters, water urgent. Reclaimed water from a sidewalk, the difficulty better than wearing a huge rock. "Down to thirty-four tons of stone, and it would be washed away. Can only build cofferdam, the blasted rock fill into the river, to the stone surfaces to fill out a pavement life and life to. The whole road repair, we can say is 'reclamation'. "Shiyi Bo said.
Future renewal
The end of November will form the second construction scheme
August 31, map lying road finally reopened. Provincial Department of Transportation Chief Engineer Chen Yuesheng, due to the steep slope pavement, the curves are sharp, narrow embankment, leading to less capable, and there along the hidden temporary sidewalk reopened only emergency vehicles and survey and design personnel.
Yuan Quan said that due to high water levels along the river, lake has not been handled, the way a lot of pressure PAT. Still, will try to speed up the sidewalk widening strengthening, to facilitate post-disaster reconstruction.
Generally reflect the already completed sections of road will be lying secondary reconstruction. "The current design units have been lying on the road map for full range of investigation, the preliminary estimate may be made next week, the design." Yuan Quan said, as proven in the development trend of geological disasters in the road, the secondary construction program is expected to be determined by the end of November . Source: Sichuan Daily
