It is the first barrier to waterproofing the entire project. It has a wide range of uses. It can not only be used for waterproofing construction of building walls and roofs, but also for waterproofing construction in tunnels, roads, basements and other places. The function of waterproof membrane is the same as that of waterproof coating, but the performance in construction is different.

[0003] For example, a Chinese patent with publication number CN214160326U discloses an asphalt scraping device for waterproofing coiled material production, including an installation vehicle, an asphalt tank is installed on the upper side of the installation vehicle, and two discharge pipes located at the bottom of the installation vehicle are connected to the lower side of the asphalt tank. A rotating drum rotatably connected to the middle of the bottom of the installation vehicle is provided between the two discharge pipes, and a rectangular rod is provided on the lower side of the rotating drum, and a plurality of scraping strips are fixedly connected to the lower end of the rectangular rod. The utility model firstly scrapes the asphalt flowing out of the asphalt tank by a plurality of scraping strips at the lower end of the rectangular rod, so that the asphalt is evenly distributed on the surface of the coiled material, and then the asphalt is uniformly scraped and leveled by the scraper at the rear side of the installation vehicle, so that the asphalt is evenly applied on the surface of the coiled material, changing the traditional manual scraping method, which not only reduces the labor burden of workers, but also speeds up the scraping efficiency of asphalt, and compared with the traditional scraping method, the scraping is faster and more uniform.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: when the above device is working, asphalt flows directly out of the asphalt tank, and the asphalt discharge width cannot be controlled according to the width of the roll. At the same time, after the above device is used, asphalt will still exist in the asphalt tank. If the asphalt is not cleaned, it will cause the asphalt in the asphalt tank to solidify, and the asphalt in the asphalt tank may cause blockage. In view of this, we propose a waterproof roll asphalt scraping device. Utility Model Content
