The invention discloses a membrane bag sand levee slope settlement prediction method and system based on a neural network, and belongs to the technical field of prediction systems.The method comprises the steps that construction parameters, foundation monitoring data and geological exploration data of a membrane bag sand levee slope are obtained; performing feature fusion by analyzing correlation between the construction parameters and the compression amount of each foundation soil layer in the time dimension and between the foundation monitoring data and the compression amount of each foundation soil layer to obtain fusion time sequence features; and on the basis of the geological exploration data, using a settlement prediction model and fusion time sequence characteristics, predicting each compression amount by analyzing the pore drainage rate of each foundation soil layer, outputting a settlement prediction result of the membrane bag sand bank slope, identifying the settlement abnormal risk of the membrane bag sand bank slope, and outputting the settlement risk grade of a preset construction point. Therefore, by implementing the method and the device, the problem that the predicted total settlement amount of the film bag sand bank slope is not accurate enough due to the fact that the influence of the bank slope foundation structure on the settlement amount in the construction process is not completely considered in the prior art can be solved.

The utility model relates to an ear hanging type compression clamping device for postoperative treatment of ear lobe keloid, which comprises an ear hanging pipe and a clamping structure. The ear hanging pipe is composed of a first hose, a second hose and a third hose, and the shape and length thereof are adjusted by cooperating the adjusting convex block with the adjusting installation groove. The clamping structure is connected with the ear hanging pipe through a spherical adjusting member, and the clamping angle of the clamping bottom plate and the adjusting clamping plate can be adjusted. The device is made of medical-grade silicone rubber material and has a hydrophilic lubricating coating on the surface, thereby having good biocompatibility and wearing comfort. The device is used for postoperative treatment of ear lobe keloid, prevents recurrence through compression, and can be used for drug treatment through cooperation of the medicine storage groove and the medicine injection interface.

The application relates to a fire hose wear resistance detection equipment and a detection method in the technical field of fire-fighting equipment detection, which comprises a case, a center frame fixedly installed at the middle of the inner wall of the case, a polishing mechanism rotationally arranged on the inner wall of the center frame, a rotating mechanism arranged on the center frame and used for driving the polishing mechanism to rotate, a first cap and a second cap, a fire hose body passing through the polishing mechanism arranged between the first cap and the second cap, and a fixing piece arranged at one end of the first cap and one end of the second cap and used for sealing the fire hose body. The fourfold guarantee effectively eliminates the gap between the fire hose and the friction component generated by the negative pressure adsorption mode of the prior art, ensures that the wear simulation is highly consistent with the actual fire scene hose dragging wear state, greatly improves the accuracy and reliability of the detection result, and meets the accurate requirement of fire hose quality detection.
