The moat in Xi'an has a history of more than 600 years. It was built in the Ming Hongwu the seventh years and the eleventh years (1374-1378). The moat, also known as the nursing moat, is the artificial protective river which the periphery of city wall circled the whole city in order to prevent military attack and guard the city defense. Nowadays, the moat bridge is the only way for the people of Xi'an outside going into this city’s inside. There are a lot of vehicles and people every day. The pressure of transportation is very high. Considering the bridge is in disrepair for many years, the Xi'an municipal government recently carried out the loading test of the moat bridge. They monitored the damage of all parts of bridge and work status, and then determined whether it needed an overhaul and reinforcement. The company which participated in this reinforcement project is Nanjing Mankate. The responsible person of this company said that Xi'an moat was the facade of Xi'an. Whether from the perspective of historical significance or now the importance of traffic, it was a very important project. From monitoring to construction we must use the most specialized equipment and materials.
Through monitoring, the cracks of the main arch were more serious. And there were different degrees of water seepage and calcification. The four arch feet of the main arch all had the vertical cracks. The largest crack cut through the cross section of the whole arch. The maximum width of cracks could be up to 4.0mm. Therefore, the implementation of the reinforcement program was imminent. In terms of the reinforcement program, the technical staff said that we must use the current internationally advanced carbon fiber reinforcement materials because the deck was damaged seriously. Besides, the moat soaked in the water throughout the year. Both water seepage and moisture corrosion were very serious. The ordinary steel reinforcement was very susceptible to corrosion. So they used the Mankate's carbon fiber cloth. The biggest advantage of this material is that the loading of building increases obviously. And it will not be affected by chemical or moisture corrosion and is also pollution-free.
Under the guidance and construction of Mankate’s technical personnel, the current Xi'an moat isn’t found any new cracks before and after the loading test. Through monitoring, they didn’t find any horizontal displacement of arch feet of the main arch. The construction of the whole moat reinforcement is solid and meticulous. The loading test is detailed and reliable. The reinforcement materials are advanced and durable. And it is praised by both the Xi'an City Wall Scenic Area Management Committee and the citizens.
Mankate’s carbon fiber cloth is China famous product, which has been widely used in subway, high-speed, aerospace buildings and some other projects. It is underwritten by Ping An Insurance and has passed the industry's high standards of safety identification. It is absolutely your first choice of reinforcement material.
