This application relates to a method and apparatus for analyzing community fire-causing factors based on internet commercial data, comprising the following steps: collecting multi-source internet data of the target community and its surrounding areas; constructing a dynamic community profile including structural, economic, and behavioral characteristics based on the preprocessed multi-source internet data; constructing a multi-stage fire risk prediction model and performing fire risk prediction using the multi-stage fire risk prediction model to obtain a fire risk assessment result for the target community; constructing a multi-layer heterogeneous fire graph of the community based on the fire risk assessment result; and determining the fire-causing factors and fire-causing chains of the target community based on the multi-layer heterogeneous fire graph. Real-time capture of key fire-causing factors provides strong data support and technical assurance for fire management departments to accurately locate hidden dangers and efficiently allocate prevention and control resources, contributing to improving the intelligence and refinement of modern urban community fire safety governance.

The application discloses a construction method of a shallow geothermal energy utilization system for urban communities, which comprises a pit foundation, wherein the pit foundation is sequentially provided with a bottom plate, a first soil layer, a pipe row, a first isolation layer, a second soil layer, a second isolation layer and a third soil layer from bottom to top; the pipe row forms a loop and is connected with a vertical ground-buried heat exchanger; the first isolation layer is laid by using an isolation layer laying device; and adjacent second isolation layers are fixed by a cross plate and a screw. The shallow geothermal energy utilization system can maximize the utilization of resources, meet the requirements of energy saving and environmental protection, and prolong the service life by reducing the damage rate of materials in construction by using the method. The isolation layer laying device is used in construction, so that the laid geomembrane is flat and beautiful, the burden of public personnel is reduced, and the geomembrane is convenient and easy to operate.

This invention provides a reinforcement device for the renovation of old urban community buildings, comprising a vertical reinforcement plate and a horizontal reinforcement plate. The vertical reinforcement plate has a fixing plate on its exterior, and the fixing plate has hinge seats I arranged vertically at intervals. Anchor rods are anchored to the outer sides of the hinge seats I. A wire mesh is laid on the inner surface of the vertical reinforcement plate, close to the exterior wall. The anchor rods penetrate the fixing plate, the vertical reinforcement plate, and the wire mesh and are embedded and anchored within the wall. The horizontal reinforcement plate is a square plate with hinge seats II corresponding to its upper front and rear ends. A first support rod and a second support rod are connected between the two hinge seats I and hinge seats II, respectively. Expansion bolts embedded in the wall are located at the four corners of the horizontal reinforcement plate. Anchor rods are anchored in the middle of the hinge seats II. This invention, through the combination of horizontal and vertical reinforcement plates and anchors, and through modular design, dynamic anchoring, and lightweight construction, effectively improves the structural safety of old buildings, and is particularly suitable for seismic reinforcement and exterior renovation.
