Tokyo- A truck that poured into a road suddenly opened near Tokyo caused the country's attention because trying to rescue the elderly driver. The residents near the cave took a refuge in a local school and worried about floods and leakage of sewage on Thursday. The debate on the aging infrastructure of Japan also has a new debate.

After the sewage pit appeared in Yashio City in the northeast of Toast in Toong, a 3 -ton truck fell into it. At first, the width of the sewage pit was about 10 meters (33 feet) and a depth of 5 meters (16 feet), but it has increased to twice the size since then.

It is believed that a 74 -year -old man was trapped in a flat truck. According to Yoshio's official Yoshifumi Hashiguchi, he was conscious and communicated with rescuers, but he had no response since Tuesday afternoon.

Jun Uehara, an officer of Saitama's sewer system, said that corrosion may be because strong acids continue to pass through the system and may cause a hole on the pipeline, causing a large space above the soil and forming a large space between it and between roads.

In the last visual inspection, the pipeline did not find any problems, which was required every five years. The sewage leaked from the damaged pipeline may also cause floods.

Unstable ground, there is a hollow space below, which is hindering rescue. The TV camera captured the rupture of the asphalt road and collapsed into the sewage pit, knocking down the billboard. The authorities tried to save the driver by lift the truck with a crane, but they could only restore the loading platform, and they were believed to be trapped in the driver's cabin. Officials have not successfully eliminated the sediment and dug out the driver. They also flew into the cave to see if the rescuers could climb down, but did not make any progress.

Neighbors are required to cut water. Part of the road is closed. About how long the operation will last.

According to the city, on Thursday, about 20 residents in the local junior high school shelter in the 200 -meter (656 -foot) radius at the radius of 200 meters (656 feet).

One million residents in the entire Saitama County, especially in areas where sewage and sewage flows into pipelines, are required to reduce laundry and bath to prevent them from overflowing into sewage pits. Uehara said that county officials also began to transfer the sewage from the upstream pumping station and released it to the nearby river after treatment.

When the driver is taken out, the expert will enter the sewage pit and check the sewage treatment system.

The Ministry of Land, Infrastructure and Transportation have ordered the sewage system nationwide. Among one of the most prone countries in the world, the sewage pit has aroused concerns about aging infrastructure.

Most of the major public infrastructure in Japan was built during the rapid economic growth of the 1960s and the 1970s. Yashiro's sewage pipe has a history of 40 years.
