Embodiment Construction

[0014] refer to Figure 1-4 , the specific implementation method adopts the following technical solutions: the rainfall runoff infiltration simulation experiment system on the underlying surface of the city, including the infiltration bed 1, the artificial rainfall system 2, the rainwater measurement system 3, the water quality monitoring system 4 and the computer software model system 5, the infiltration bed An artificial rainfall system 2 is set above 1, and a rainwater measurement system 3 and a water quality monitoring system 4 are installed on the infiltration bed 1. The artificial rainfall system 2, rainwater measurement system 3, and water quality monitoring system 4 are connected with the computer software model system 5, and the infiltration bed 1. The data between the artificial rainfall system 2, the rainwater measurement system 3, the water quality monitoring system 4 and the computer software model system 5 can be mutually verified.

[0015] It is worth noting tha...

Abstract

The invention discloses an urban underlying surface rainfall runoff infiltration simulation experiment system and relates to the technical field of rainfall flood management. An artificial rainfall system is arranged above an infiltration bed; a rainwater measuring system and a water quality monitoring system arranged on the infiltration bed are connected with a computer software simulating system; the infiltration bed is formed by an infiltration bed device, an independent experiment trough, a concrete foundation and an I-beam truss structure; the rainwater measuring system is formed by a double-ring permeameter, a soil moisture content testing instrument and an electromagnetic flowmeter; the system is matched with corresponding computer simulation software, can perform mutual verification with an experiment simulation system, can evaluate the risk level of rainstorm in a small river basin, which causes urban water logging, and can realize emission reduction and dispersed storage and delay of urban rainfall runoff. The system can provide early-stage experiment support for the development of cities, and is steady and reliable, strong in practicability and easy for promotion and application.

Description

technical field [0001] The invention relates to the technical field of rainwater management, in particular to a simulated experiment system for rainfall runoff infiltration on urban underlying surfaces. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It means that the city can be like a sponge, which has good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it can absorb, store, infiltrate, and purify water. "Release" the stored water and use it. According to the recent spiritual instructions of the Party Central Committee and the State Council on strengthening the "sponge city", it is proposed to use the artificial simulated rainfall system combined with the spray test bed to conduct the permeability test of urban green space and soil. The purpose of the test is to provide urban infrastructure. Construction provides some experimental data to fill in the gaps in my count...
