The application discloses a closing method of a super-large-span shore-controlled floating body chevron gate tide gate, which comprises the following steps: firstly, opening the rotating gate, emptying the medium in the water-stopping bag, and making the supporting rod in a retracted state to form a flow passage at the bottom of the gate body; then, rotating the gate body to the center of the river channel through a balance opening and closing device until the heads of the two gate bodies are closed and connected to form a stable three-hinged arch structure; then, extending the supporting rod to support on the gate bottom plate, inflating the water-stopping bag to block the flow passage; finally, closing the rotating gate to complete the closing operation. The tide gate adopting the "gate-in-gate" design has the characteristics of stable structure, flexible opening and closing, safe operation, convenient maintenance and the like, and solves the problem of water stagnation side inclination in the opening and closing process of the floating body chevron gate.

The utility model discloses a prefabricated assembly type culvert waterproof structure, which relates to the technical field of culverts, and comprises a culvert body, one end of the culvert body is fixedly connected with an inserting ring with a semi-enclosed structure, and one end of the culvert body far away from the inserting ring is provided with a connecting groove with a semi-enclosed structure; the culvert bodies are connected end to end, the culvert bodies form an end-to-end connecting structure through mutual connection of the inserting rings and the connecting grooves, the top of each culvert body is of a slope surface structure, and the connecting grooves distributed at equal intervals are formed in the top of each culvert body. According to the prefabricated culvert waterproof structure, the design that the slope surface structure is matched with the V-shaped connecting grooves is adopted for the top of the culvert, water flow can be quickly concentrated to the two sides along the slope surface and is efficiently discharged through the drainage grooves, accumulated water on the top and in the culvert can be thoroughly discharged through linkage of the added sewer system and the water diversion holes, and damage to the culvert caused by accumulated water retention is avoided; and the overall drainage efficiency is greatly improved.

This invention belongs to the field of data processing technology and proposes a method and system for identifying inefficient areas in saline-alkali land flower fields using seedling trays. Specifically, the method involves: first, acquiring the spatial boundary information of the flower field area; then, dividing the area into grids based on the spatial boundary information; periodically collecting multi-temporal remote sensing data for each grid; and constructing a time-series measurement of saline-alkali land corresponding to each grid using the multi-temporal remote sensing data; finally, determining whether there is a risk of salinity accumulation and water stagnation imbalance based on the time-series measurement of saline-alkali land. Based on multi-source remote sensing data, a dynamic imbalance risk identification model is established, effectively solving the management problems of accurately identifying potential inefficient areas and making irrigation decisions unsuitable for local conditions when flower fields are deployed over large areas in saline-alkali land. This significantly improves the landscape stability, resource utilization efficiency, and management accuracy of saline-alkali land flower systems, providing effective support for achieving large-scale, intelligent, and low-intervention landscape ecosystem operation.
