Method for selecting application mode of salt-isolating rainwater garden structure

Abstract

The invention discloses a method for selecting an application mode of a salt-isolating rainwater garden structure. The method comprises the following steps of: designing an orthogonal test and a simulation test, and self-making a rainwater garden salt return and rainfall simulation device; performing a manual control simulation test through the rainwater garden salt return simulation device and the rainfall simulation device to obtain the influence degrees of a salt-isolating layer material, a salt-isolating layer position and a filler layer thickness on a salt-isolating effect, a flood peak delay time and runoff reduction respectively; and comprehensively analyzing main influence factors of the salt-isolating effect, the flood peak delay time and the runoff reduction effect to propose the salt-isolating rainwater garden structure suitable for different functional requirements. According to the method, the salt-isolating rainwater garden most suitable for different saline-alkali environments and functional requirements is selected in a targeted and reasonable manner through comprehensive analysis of the influence degrees of the salt-isolating layer material, the salt-isolating layer position and the filler layer thickness on the salt-isolating effect, the flood peak delay time and the runoff reduction, so that the problem of targeted and reasonable selection of the application mode of the salt-isolating rainwater garden structure under different environmental conditions and functional requirements is solved.

Description

[0001] This application is a divisional application for a salt-isolated rain garden structure. The application date for a salt-isolated rain garden structure is July 30, 2019, and the application number is 201910694538.X. technical field [0002] The invention relates to the technical field of landscape gardening engineering, in particular to a method for selecting an application mode of a salt-isolation rainwater garden structure. Background technique [0003] Sponge city is an important way to realize urban stormwater management and one of the important media to realize ecological city construction. It means that cities have good "elasticity" in adapting to environmental changes and dealing with natural disasters caused by rainwater. The construction of the city in this way can make more rational use of rainwater. To expand, use materials that can absorb water to pave cities, such as residential areas, street walks, flower ponds, etc., and treat them as sponges, which can ...
