The application provides a scour-resistant river bottom paving structure and relates to the technical field of river bottom paving. The scour-resistant river bottom paving structure comprises a river channel foundation, a longitudinal beam is arranged at the center line of the river channel foundation, a plurality of cross beams are distributed on the longitudinal beam, a regular beam grid framework is formed by the longitudinal beam and the cross beams, and the beam grid framework is paved with chain bricks. The chain bricks are provided in an I-shaped structure, the two end portions of the chain bricks are provided in a clamping block structure, the two side waist portions of the chain bricks are provided in a clamping groove structure, the clamping block structure is tightly embedded in the clamping groove structure, and the plurality of groups of chain bricks are tightly assembled. The utility model adopts the paving form of the prefabricated I-shaped chain bricks and the beam grid framework, the specific structure form is the I-shaped chain brick paving, the tight embedding prevents the loosening and washing away, the longitudinal beam and the cross beam of the reinforced concrete structure are arranged in the middle of the river channel to form the paving beam grid framework and reinforce the paving of the chain bricks, and the scour-resistant ability of the paving during the storm surge is improved.

A system for lifting a structure above flood water during storm surges and other severe weather events wherein the structure has a reinforced support frame that is slidably attached to multiple vertical poles positioned around the structure. The structure may be raised up and down the poles using an automated lifting mechanism or by one or more floating pontoons secured below the structure that rise and fall with any flood waters.

This product offers excellent drainage, prevents the accumulation of sand and debris, and is highly user-friendly. Furthermore, it provides a high-tide protection vehicle stopper that can withstand storm surges. [Solution] A high tide countermeasure vehicle stopper is provided by attaching a sheet holding member (11) to the lower end of the land side (1a) of a rectangular steel pipe (1) which is installed floating above the ground surface (G) so as to form a gap between it and the ground surface (G). The sheet holding member (11) has a sheet member (2) that closes the gap and has its tip wrapped towards the sea side (S) to contact the ground surface (G), a comb-shaped holding part (11a) that holds the tip of the sheet member (2) so as not to be pushed towards the land side by seawater, a plurality of openings (11b) provided adjacent to the holding part (11a) that do not obstruct rainwater from the land side from flowing to the sea side S, and three L-shaped fixing parts (11c) that are fixed to the ground surface (G) on the land side.

This invention discloses a method and system for identifying storm surge inundation ranges based on multi-source remote sensing imagery, particularly relating to the field of image analysis. The method includes: acquiring pre- and post-disaster images and digital elevation model (DEM) data within a target area; performing feature extraction and multi-source image fusion to generate a broad-spectrum suspected inundation area image; identifying complex underlying surface regions from the broad-spectrum suspected inundation area image based on pre-disaster optical images and obtaining corresponding binary mask images; performing texture feature analysis and pixel-level classification on each of the complex underlying surface regions to identify the actual water body regions; generating a preliminary inundation range map based on the actual water body regions of each complex underlying surface region; and performing terrain connectivity analysis on the preliminary inundation range map to generate a final storm surge inundation range map. This application can selectively filter out texture interference from different complex underlying surfaces in images based on pre- and post-disaster storm surge images, thereby improving the accuracy and reliability of storm surge range identification.

The application discloses a coastal city road anti-seawater backflow and salt mist corrosion protection method and system, comprising: through collecting multi-dimensional data such as salt mist concentration, seawater backflow history, road structure characteristics, protection layer thickness and meteorological elements, outputting corrosion degree grades at different time nodes through a salt mist corrosion progressive prediction model, generating a salt mist diffusion thermal map by using a salt mist diffusion trajectory tracking algorithm, calculating seawater backflow related data through a storm tide surge coupling algorithm, importing the data into a road moisture-proof protection decision platform, and carrying out multi-factor coupling analysis combined with parameters such as corrosion resistance threshold of protection materials and structure anti-permeability coefficient, finally outputting targeted adjustment instructions for protection layer repair, drainage system optimization, corrosion-resistant coating spraying and interception facility layout. The application realizes accurate and intelligent formulation of the protection scheme, and effectively improves the protection efficiency of the coastal city road against seawater backflow and salt mist corrosion.
