Vantai24h - On 4/9/2017, Dan Viet newspaper reported, the cause of cracking the road to the overpass in Hai Phong is assessed by authorities as due to weather. However, construction experts say that it must look at "human ear", not just poured in the weather.
According to the information, Dinh Vu - Nguyen Binh Khiem flyover has not been put into operation, but there has been a cracks in the path leading to the bridge. According to the report of the Department of Transport Hai Phong, the cracks are on the path of two ends of the bridge, the claw connecting from the old route to the bridge, length 15-30m, crack width 2-10mm.

Specifically, heavy rain and storms combined with tides (because of bridges of the river system, Dinh Vu seaport), when constructing drainage system on both sides, plus the digging of foundations 4m deep, leading to suction water for construction has changed the geological conditions have caused the surface subsidence of the path, causing cracking.
However, Prof. Dr. Nguyen Van Hung - former President of the University of Civil Engineering said: "In the construction of bridges, before work had to forecast to the weather. Now the problem is due to the weather or the temperature is not so, must look at the ear.
According to Prof. Nguyen Van Hung, through the picture recorded on the bridge over Dinh Vu - Nguyen Binh Khiem, vertical cracks occur may be due to two sides of the talus does not handle the soil well. "Longitudinal cracks appear on the path mostly due to embankment. Poor soil may be due to weather but may also be caused by construction, which will create subsidence affecting the road, "said the former University of Construction. Normally, before the construction of the weather is predicted to affect how, so according to Mr. Hung "if the construction is good, the weather is not affected."
Le Van Binh - Deputy General Director of Transportation Design and Consulting Company (TEDI) - said that through the inspection and survey of the bridge overpass Nguyen Binh Khiem - Dinh Vu Construction is completed to ensure the correct design. Cracks in the path do not affect the quality of the bridge. "The best solution is to urgently construct the sewer, the two way roads, then treat the foundation," said Binh.
Assoc. Prof. Nguyen Van Hung proposed to handle two sides of the slope to prevent slipping into two patches, hatch hips.
Mr. Nguyen Xuan Binh - Vice Chairman of Hai Phong People's Committee asked the Department of Transport, contractors, supervisors, consultants and related units should continue to monitor subsidence, cracking, look at the problem in a way. General inspection and evaluation of the cause, quickly dealt with the state of the crack.
