Description

Technical Field

[0001] The present application relates to the technical field of building restoration, and in particular to a system and method for reinforcing and repairing arcade building structures in historical and cultural blocks. Background Art

[0002] As an architectural form with profound historical value and regional characteristics, arcades carry rich cultural memories and traces of urban change. However, with the erosion of time, environmental corrosion, and accelerated urbanization, many arcade buildings located in historical and cultural districts are gradually facing problems such as structural aging, wall hollowing, and foundation settlement, and are even vulnerable to natural disasters such as earthquakes. Currently, the restoration methods for arcade buildings in historical and cultural districts mostly use ordinary building restoration methods, which have two major flaws: First, traditional detection methods do not consider the impact of environmental factors such as high humidity and frequent typhoons in the southern coastal areas on structural damage, resulting in insufficient durability of reinforcement solutions; second, material adaptation relies on manual experience and judgment, lacking analysis of the salt crystal growth pattern of the gray plastic layer and the interface stress between the new and old materials, resulting in alkali cracking and visual faults on the repair surface. To address the above problems, no effective solution has yet been proposed. Summary of the Invention

The method for reinforcing and repairing the arcade building structure in the historical and cultural block according to claim 2 is characterized in that: Dynamic commercial flow planning is achieved through the following methods: Construct a spatial conflict matrix of visitor heat maps and load-bearing wall distribution; The visual interference index is verified by projecting holographic projections of historical shop signs through augmented reality equipment.

9. The method for reinforcing and repairing the arcade building structure in the historical and cultural block according to claim 2 is characterized in that: The environmental responsive monitoring network includes: pH-responsive hydrogel microspheres are embedded in the gray plastic layer, and their color changes reflect the depth of acid rain erosion. An array of magnetostrictive sensors is deployed along the ground ring beam to monitor the uneven foundation settlement trend in real time; A weathering rate prediction model based on LSTM network is constructed to dynamically optimize maintenance cycle parameters.

10. The method for reinforcing and repairing the arcade building structure in the historical and cultural block according to claim 2 is characterized in that: After conducting a typhoon and pedestrian flow coupled load simulation based on the repaired three-dimensional structural model, generating a three-dimensional activation plan in combination with dynamic commercial flow planning, and deploying an environmentally responsive monitoring network, the self-repair mechanism is activated. When the crack propagation rate exceeds a threshold, the following actions are performed: Activate the microcapsules in the shape memory mortar to release the healing agent; Adjusting the visual saliency of new components through electrochromic coatings; The shrinkage characteristics of the rattan support are utilized to adaptively compensate for structural deformation.
