The stone road in Tiananmen Square, built in the 1950s, was renovated yesterday and the new road will be unveiled before the National Day.
The reporter saw at the scene that the bus lane in the north of the square had been blocked by the blue fence, and the new granite slabs to be replaced were also delivered to the square. Relevant persons said that the standards for the construction and repair of the project were repeatedly demonstrated by relevant experts, and the improvement suggestions were made after the stone materials and masonry techniques were put forward.
According to reports, in this dressing, the broken, loose and sinking slabs will be removed first, the original cement concrete foundation under the clean slabs will be removed, and then 10 cm thick new concrete will be laid. Finally, the paving is 100 cm long and 50 cm wide. New granite slabs with a thickness of 25 cm are then filled.
A person from the Beijing Municipal Engineering Office said that the stone road in front of Tiananmen Square is 400 meters long and 80 meters wide and has been in service for 50 years. In the past two years, due to the heavy-duty vehicles on the bus lanes, the traffic load is very large, which has caused the unrepaired stone roads in the front of the working people's cultural palace to be damaged, which has affected the driving of public transport vehicles. The repair is expected to replace more than 200 stone slabs.
