TECHNICAL FIELD

[0001] The present application belongs to the technical field of masonry ancient tower repair, and particularly relates to a hollow brick tower top collapse site repair method. BACKGROUND

[0002] Most existing masonry ancient towers have a history of several hundred years or even thousands of years. Under the influence of earthquakes, rain erosion, root splitting and natural destruction, many masonry ancient towers have serious collapse at the top, the tower top and pagoda fin do not exist, the tower chamber is exposed to the outside, and the top is growing shrubs and weeds year after year under the action of wind force. Therefore, for the ancient tower with top collapse, rescue protection and reinforcement are urgently needed to avoid further damage.

[0003] At present, there are mainly two kinds of reinforcement methods for the top collapse of masonry ancient towers. One is to restore according to historical records and present image data, or to restore according to the shape of the same type of brick tower. The second kind of tower top collapse ancient tower has no related data of ancient tower top, and cannot find the same period and same shape ancient tower. Usually, the ancient tower top is reinforced, and the rain disc is installed to guide the flow of rainwater on the tower top and protect the tower top.

[0004] For the second type of tower top collapse ancient tower, since the ancient tower top is mostly inaccessible, it is difficult to maintain, and therefore whether a steel structure rain disc, a glass steel rain disc or a wood structure rain disc is used, the water inlet is easy to be blocked by bird droppings, fallen leaves and other garbage, so that the ancient tower is damaged due to rainwater penetration.
