DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] The utility model provides Figure 1-5The pipe network silt reduction device shown in the figure for municipal drainage engineering comprises a culvert 1, a neck pipe 2 is welded on the culvert 1, the neck pipe 2 is connected to a manhole cover frame 3 by bolts, the manhole cover frame 3 is rotated to set a manhole cover 4, a deposition plate 5 is obliquely arranged in the culvert 1 and located at the lower side of the manhole cover 4, a steel bar for support is welded at the bottom of the deposition plate 5, and the inclination angle is 20°. The surface of the deposition plate 5 is set in a serrated shape to facilitate the retention of gravel, soil, etc., a scraper 6 is arranged on the deposition plate 5, a slag storage box 7 is arranged on one side of the deposition plate 5, an opening 8 is arranged on the slag storage box 7 corresponding to the side of the deposition plate 5, and an operating lever 9 is arranged on the scraper 6, which can be manually taken The operating lever 9 is held to scrape the deposited sand and soil on the deposition plate 5 into the slag storage box 7 through the scraper 6. After the storage is full, the deposition plate 5 and the slag storage box are cleaned manually; the upper end of the filter screen plate 12 is rotatably connected to the front end surface of the slag storage box 7 through a hinge, and a baffle is arranged on the front end surface of the slag storage box 7 and located outside the lower end of the filter screen plate 12. The baffle is rotatable, and the rotation is adjusted to see whether the baffle blocks the filter screen plate 12. When the baffle rotates to block the filter screen plate 12, the filter screen plate 12 cannot be opened. When the baffle rotates to leave the filter screen plate 12, the filter screen plate 12 can be opened, and it is convenient to take out the sand and soil stored inside after opening.

[0020] As another embodiment of the present application, the scraper 6 is connected to one end of an electric telescopic rod 10, and the electric telescopic rod 10 is arranged on the outside of the culvert 1. A waterproof sealing shell is arranged on the outside of the electric telescopic rod 10. The scraper 6 can be pushed by the electric telescopic rod 10 to scrape the gravel and soil on the deposition plate 5 into the slag storage box 7.
