At the end of it, the construction of the two repair sections of the Great Wall on the northern suburbs of Beijing was under construction. The "West Wall" on the west side of the Arrow Capital Great Wall is the place where the fourth renovation project of the Great Wall of the Great Wall is located. There are 8 enemy platforms on the wall with a length of 1678 meters. The renovation project in the fourth phase will be completed at the end of October, and the project has been completed about 70%.

Great Wall repair still adheres to the principle of "minimum intervention, repairing the old as the old", try to use old bricks and follow the ancient method. On the premise of ensuring the safety of the Great Wall's body, the "old" of the Great Wall has been retained. Mature experience.

The "Western Wall" on the southeast, about 486 meters long (141 to 145 enemy platforms) is undergoing a "research repair". Different from general repair projects, research repair must not only discharge and reinforce, but also cooperate with multi -disciplinary cooperation through archeology, construction, materials, construction technology, plants and other disciplines to study the evolution process of the Great Wall ontology, the cause of the disease, and the environment. At the scene, Shang Yan, an associate researcher at the Beijing Archaeological Research Institute, pointed at a collapsed wall of the enemy platform on No. 145 and said: "The disability is part of the culture of the Great Wall ancient heritage. More people understand the root causes and collapse of the wall. "

Since 2021, Beijing has shifted the focus of Great Wall protection work from the general protection project of the Great Wall to a research repair project. This is a new exploration of the Great Wall protection and repair. Through preliminary archeology, the research repair of the Great Wall of Arrows has been excavated at 145, 144, and 143. Cultural security personnel clarified the architectural shape and engineering practices of the enemy platform. For the first time, they found the relics of the Ming Dynasty fire, stove address and other living facilities inside the enemy desk. The subsequent repair plan provides a design basis.

The Great Wall Repair Project is a key project for the construction of the Great Wall National Cultural Park (Beijing Section). At present, the Great Wall of about 10 kilometers has been completed and repaired by 5 kilometers. With the consent of the State Administration of Cultural Relics, the nation's first Great Wall Protection and Repair Practice Base was established at the foot of the Great Wall of the Arrow Capital in September 2020, which has played a demonstration effect on the national Great Wall protection work.
