Embodiment Construction

[0052] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0053] In recent years, numerical simulation technology has made major breakthroughs in the research of climate meteorology, and computer simulation can more accurately reflect the real climate, meteorology, weather and other atmospheric motion processes at different spatial scales.

[0054] Using coarse-grid global Meteorological Reanalysis Data (Meteorological Reanalysis Data) as the background field and providing initial and boundary value conditions to drive the Regional Climate Model (RCM) for numerical integration, a higher spatial-temporal resolution meteorological climate information.

[0055] Meteorological reanalysis data is the gridded data obtained by assimilating meteorologic...

Abstract

The invention discloses a municipal rainwater pipe network planning and designing system based on urban rainfall spatial distribution characteristics. The system comprises a gridding urban rainfall simulation module, a gridding urban rainstorm intensity calculation module, a rainwater pipe network planning design and management module based on urban rainfall spatial distribution characteristics, a rainwater pipe network planning design scheme evaluation module based on the urban rainfall spatial distribution characteristics, a data storage module and a main controller. Urban rainstorm intensity parameters used in municipal rainwater pipe network planning and design are gridding two-dimensional data with spatial attributes and reflect rainfall characteristic spatial differences of urban scales, so that refined planning and design of the municipal rainwater pipe network are realized, construction of the municipal rainwater pipe network is more scientific and reasonable, and the construction efficiency is improved. And the demand target of urban rainwater drainage is better matched.

Description

technical field [0001] The invention relates to the technical field of municipal drainage engineering, in particular to a municipal rainwater pipe network planning and design system based on the spatial distribution characteristics of urban precipitation. Background technique [0002] The municipal rainwater drainage network is an important part of the urban drainage system, which guarantees the safety of life and property of urban residents and the normal operation of the urban system. With urbanization and economic development, the scale and project investment of municipal rainwater drainage pipe network are becoming larger and larger. The rationality of pipe network design often directly affects the investment scale of the entire drainage project construction, as well as the performance and maintenance results of the drainage system. . "Outdoor Drainage Design Standards" (GB 50014-2021) stipulates the return period standards for stormwater design of drainage systems in d...
