The present disclosure relates to a track map labeling method, device and system. The track map labeling method is applied to a labeling vehicle, and the method comprises: in response to a user's operation on the labeling vehicle, determining a working state in which the labeling vehicle is located, the working state comprising at least a labeling working state and a point searching working state; when it is determined that the labeling vehicle is in the labeling working state, determining whether a current labeling position is acquired; when it is determined that the current labeling position is acquired, labeling the current labeling position to obtain labeling information corresponding to the current labeling position. Through the present disclosure, the informationization of track map labeling data can be realized, the work efficiency is improved, and the introduction of human errors in the work process is avoided.

This utility model discloses a stormwater drainage system for high-fill roadbeds, relating to the field of stormwater drainage technology. It includes stormwater pipes and inspection wells. Each inspection well comprises a foundation, well base, well cylinder, cast-in-place cylinder, pressure-bearing ring, and well cover. A guide channel is located at the center of the top surface of the upper boss. The inner cavity of the stormwater pipe is connected to the guide channel. The inspection well also includes a receiving bucket and a guide assembly. The guide assembly guides the stormwater flowing in from the well cover to the receiving bucket. The receiving bucket is used for sediment settling in the stormwater. The receiving bucket is press-fitted to the edge of the top surface of the upper boss. The inner wall of the well cylinder, away from the receiving bucket, is rotatably connected to the top of the guide assembly. The guide assembly can rotate until its bottom end overlaps the top of the receiving bucket. Stormwater flowing in from the well cover flows along the guide assembly into the receiving bucket, where sediment settles, before overflowing into the guide channel and stormwater pipe, preventing sediment from entering the stormwater pipe and thus avoiding blockage.

The application discloses a kind of high air permeability nonwoven fabric mesh belt and preparation method thereof, belong to mesh belt technical field, modified polyester particles and polyolefin elastomer particles are stirred and mixed, to obtain mixed material, mixed material is dried and pre-crystallization;Mixed material is extruded, granulation, to obtain composite polyester particles;Composite polyester particles are extruded into shape, wet oiling, winding into shape, prepare polyester monofilament;Polyester monofilament includes warp and weft, the cross-sectional shape of warp is circular, and the cross-sectional shape of weft is right-angled trapezoidal, finally warp and weft are woven into high air permeability nonwoven fabric mesh belt;Through structural design, in the case where it does not increase open porosity, increase the open area, so as to ensure the stability of mesh belt high speed, increase the mesh belt air permeability, increase the exhaust effect of exhaust fan, also make nonwoven fabric fiber have better flat effect, unnecessary to replace mesh belt in different specifications nonwoven fabric production process, help to improve work efficiency.
