The invention discloses a deformation monitoring and early warning method and system for early warning of slope disasters, and the system comprises a geological grid and mark layout module which is used for dividing grids with different densities according to the height and slope rock-soil layer data and a profile map, determining the three-dimensional coordinates of nodes, and embedding passive acoustic vibration marks; the unmanned aerial vehicle inspection planning module determines the number of unmanned aerial vehicles and generates a flight path and equipment parameters; the multi-modal data acquisition module controls the unmanned aerial vehicle to acquire sound vibration, three-dimensional point cloud and environmental data; the model training module constructs a physical constraint function and takes multi-modal data as an input / output theoretical physical quantity; and the early warning judgment module sets a matching degree interval, determines triggering conditions according to normal, attention and early warning intervals of historical data, starts encryption inspection by three times of attention, and triggers an alarm by single time of early warning. According to the invention, encrypted inspection or early warning can be timely started according to the matching degree interval and the trigger condition, and the accuracy and timeliness of slope safety monitoring are effectively guaranteed.

The invention discloses a preparation method of a leakproof plastic cup lid, which comprises the following steps: S1, taking high-density polyethylene and thermoplastic elastomer as main raw materials, and taking a filler, an antioxidant and a lubricant as auxiliary additives, so that the raw materials and the auxiliary additives are fully and uniformly mixed; s2, adding the uniformly mixed raw materials into a charging barrel of an injection molding machine for melting, and carrying out injection molding by adopting an injection mold; s3, the formed cup cover is cooled in the mold, so that the cup cover is fully shaped; s4, the taken-out cup cover is put into a burr cleaning mechanism for deburring treatment.The manufacturing method enables the cup cover to be compact in structure and uniform in texture after being formed, so that liquid is effectively prevented from leaking from the cup cover, burrs at an opening of the cup cover are effectively removed in an automatic centrifugal deburring mode, the sealing effect of the cup cover is further improved, and the quality of the cup cover is improved. And the leakage condition caused by gaps caused by burrs is avoided.
