This invention discloses a method and apparatus for identifying road changes using remote sensing imagery. The method includes: acquiring new and old remote sensing images of unlabeled roads; cropping the remote sensing images; comparing the cropped road images; inputting the compared road change images into a deep learning model for self-supervised training to obtain a pre-trained model; training the pre-trained model using labeled road remote sensing images to obtain a classification and recognition model; and inputting the desired road change images into the classification and recognition model by transferring the parameters of the self-supervised model to obtain the road change results. The method provided by this invention can intelligently identify road changes by eliminating the need for manual labeling, achieving high efficiency, and reducing costs, thus enabling efficient monitoring and dynamic supervision of road changes. This provides technical and data support for promoting traffic road maintenance and optimization, and implementing road hazard detection and remediation.

The invention relates to the technical field of anchor cable drilling positioning, and discloses an NPR anchor cable construction drilling orientation controller which comprises a mounting plate, an electric push rod is mounted on one side of the mounting plate, a fixing plate is connected to the output end of the electric push rod, a mounting seat is arranged below the fixing plate, and a height adjusting mechanism connected with the fixing plate and the mounting plate is arranged on the mounting seat. A containing cavity is formed in the bottom end of the mounting base, a spherical base is arranged in the containing cavity, a mounting shaft rotationally connected with the mounting base is fixedly connected to the middle of the spherical base, an angle detection piece is arranged at one end of the mounting shaft, a direction adjusting assembly connected with the mounting shaft is arranged in the containing cavity, and a connecting rod is fixedly connected to the bottom end of the spherical base. The bottom end of the connecting rod is fixedly connected with a limiting cylinder; according to the NPR anchor cable drilling device, a drill rod can be conveniently clamped during NPR anchor cable construction drilling, directional drilling of the drill rod is effectively achieved, drilling stability and drilling quality are improved, and convenience is provided for NPR anchor cable construction.

The application relates to the technical field of waterproof material processing, in particular to a waterproof roll material film pasting device. A leveling mechanism for adjusting the distance of a positioning assembly relative to materials is arranged on the positioning assembly. The function of the positioning assembly is to adjust the film pasting speed along with the movement of the leveling mechanism. A film pressing roller is arranged on the side, away from the leveling mechanism, of the positioning assembly. The film pressing roller adjusts its position along with the movement of the positioning assembly. A gas guide needle is arranged on one side of the leveling mechanism. A vertical rod is arranged on the side, close to the leveling mechanism, of the gas guide needle. The vertical rod changes the position of the gas guide needle relative to the materials through the movement of the leveling mechanism. The function of the gas guide needle is to remove bubbles along with the movement of the leveling mechanism. The application solves the problem of low coincidence rate of the anti-sticking film and the waterproof roll material in the film coating process of the self-adhesive polymer modified asphalt polyester waterproof roll material.
