Description

Technical Field

[0001] The present invention belongs to the technical field of measuring the water-passing capacity of curbstones, and in particular relates to a method and device for measuring the water-passing capacity of perforated curbstones in a sponge city. Background Art

[0002] In the construction of sponge cities, it is a common practice to make holes in curbstones, which aims to improve the city's ability to absorb, store and utilize water resources such as rainwater. However, due to the lack of design standards and design methods, some problems have arisen in engineering practice. For example, the water collection efficiency of curbstones without recessed holes is low, which can easily cause poor drainage. In order to solve these problems, some researchers used the flow calculation method of the lateral ditch and vertical grate rainwater outlet to perform detailed calculations on an engineering case and found that when the curbstone opening is recessed, the water collection efficiency is greatly improved. Therefore, recessed curbstone openings should be used preferentially in the design to improve the water collection efficiency and solve the problem of poor drainage.

[0003] In addition, in response to the lack of calculation of the water-passing capacity of perforated curbstones, this calculation method provides a reference basis for the calculation of the water-passing capacity of perforated curbstones in actual projects, which facilitates the reasonable design and arrangement of the opening position and opening density of perforated curbstones.
