Problems solved by technology

When studying urban rainfall-related issues, the surface runoff and infiltration data of different hardened pavements in the city are mainly obtained through some assumptions, and after simplifying the actual problem, the runoff model or empirical formula is used to calculate the data, which makes the research There is a large error between the results of the problem and the actual situation, and there are few methods to accurately measure the surface runoff, infiltration and other data in a certain area through instruments

Abstract

The invention discloses a surface runoff measuring instrument for an urban hardened pavement. The surface runoff measuring instrument is characterized by comprising a surface runoff gathering device (1), a surface runoff measuring device (2), a runoff recording device (3) and a housing (4); the water outlet of the surface runoff gathering device (1) is connected with the water inlet of the surface runoff measuring device (2); the surface runoff measuring device (2) is connected with the runoff recording device (3); the water inlet of the surface runoff gathering device (1) is arranged outside the housing (4); the water outlet of the surface runoff gathering device (1), the surface runoff measuring device (2) and the runoff recording device (3) are all arranged in the housing (4). The surface runoff measuring instrument for the urban hardened pavement can supply accurate and reliable data for researching problems of urban rainwater utilization, rainwater discharging pipe network design, urban hydrologic cycle, etc.

Description

technical field [0001] The invention relates to a surface runoff measuring instrument for urban hardened pavement, which belongs to the technical field of measuring equipment. Background technique [0002] With the improvement of the level of urbanization and the rapid development of the economy, the problems caused by urban rainwater such as large loss of rainwater resources, serious rainwater runoff pollution, increased risk of urban floods, intensified soil erosion, groundwater table decline, and ground subsidence have become more and more prominent. come out. In order to effectively utilize urban rainfall and solve ecological and environmental problems, it is essential to study urban surface runoff. At present, the urban surface runoff generation model has been studied in depth, but the simulation of the surface runoff process of different underlying surfaces in the city is still relatively rough. When studying urban rainfall-related issues, the surface runoff and infi...
