Load test method and device for rail transit rail beam maintenance evacuation channel
The invention discloses a load test method and device for a rail transit rail beam overhaul evacuation channel, and relates to the technical field of bridge engineering, and the method comprises the steps: determining a load test scheme of the overhaul evacuation channel based on technical data and structural analysis of a to-be-tested bridge, thereby determining a detection point and a load loading point of the overhaul evacuation channel; based on a traction mode, lifting a water pipe and a plurality of buckets below the bridge to the bridge floor; water buckets are sequentially placed on the determined load loading points, water injection operation is conducted in the water buckets according to the load loading force of the current load loading point in the load test scheme, and load loading of the overhaul evacuation channel is achieved; cross section strain and deflection data of the overhaul evacuation channel in the loading process are obtained in real time through sensors arranged on the detection points and compared with theoretical values, and the load test of the overhaul evacuation channel is achieved. According to the invention, the problem that it is difficult to complete the load test of the track beam maintenance evacuation channel in a short skylight time at present can be effectively solved.
