The application relates to the field of cloth technology, in particular to a moisture and fertilizer preserving grass preventing cloth. The cloth body is sequentially provided with a reflecting layer, a waterproof layer, a water absorbing structure layer and a reinforcing layer from an outer surface to an inner surface, at least one water guide hole is arranged in the reflecting layer, the waterproof layer and the reinforcing layer, and the water guide hole of the reflecting layer is communicated with the water guide hole of the waterproof layer. By arranging the water guide holes communicated with each other in the reflecting layer, the waterproof layer and the reinforcing layer, and in combination with the water absorbing structure layer, effective water conduction and penetration are realized, and the problems of surface water accumulation or water shortage at plant roots caused by the lack of a water draining and ventilating mechanism of the existing grass preventing cloth are solved.

The application relates to the technical field of vehicle fault analysis, and discloses a vehicle fault analysis method and device, computer equipment and a storage medium, the method comprising the following steps: when detecting that a target vehicle is abnormal based on vehicle condition information of the target vehicle, determining fault information of the target vehicle; performing word segmentation and label processing on the vehicle condition information and the fault information to obtain a first information type and a first information value; generating input text based on a preset language template, the first information type and the first information value; inputting the input text into a preset vehicle fault analysis model to obtain a vehicle fault analysis result. The application can respond to fault conditions in a timely manner, avoids dangerous consequences caused by the fact that vehicle abnormal information cannot be fed back in a timely manner due to negligence or lack of experience of a user, the input text is input into the preset vehicle fault analysis model to obtain the vehicle fault analysis result, vehicle fault analysis can be performed remotely and in real time, and a conclusion can be given, and human resources are saved.

The mute elevator shaft is arranged outside an elevator and comprises a plurality of hollow plate units arranged in a connected mode, each hollow plate unit comprises a concrete shell and a plurality of layer plate assemblies arranged in the concrete shell, the plurality of layer plate assemblies and the concrete shell are enclosed, and a plurality of cavities are formed in the hollow plate units. And the cavity is filled with a sound absorption part. According to the mute elevator shaft, the elevator shaft body is formed by splicing the multiple hollow plate units, the concrete shell is used for providing a stable structure foundation, the multiple cavities defined by the internal laminate assemblies and the shell are matched with the filled sound absorption parts, a sound insulation and absorption system is constructed, and starting from the overall structure, the sound wave propagation path is divided through the cavity structures, and the sound absorption effect is improved; and noise energy is directly adsorbed by means of the sound absorption part, primary efficient weakening of various noise in elevator running is achieved, convenience is improved through the modular splicing mode, and the structural stability and the mute requirement are both considered.
