specific Embodiment approach

[0072] Further, as a specific implementation of the analysis method provided by the present invention, calculating the water seepage rate according to the change in water content includes:

[0073] According to the total amount of precipitation after reaching the saturation state, the total amount of drainage after reaching the saturation state, and the time taken to reach the saturation state, the overall seepage rate of the earthwork is calculated. The relationship is:

[0074]

[0075] Among them, Q drop Is the total amount of precipitation after reaching saturation; Q row In order to reach the saturation state, the total amount of drainage, that is, the total amount of water flowing out from the upper surface of the earthwork after reaching the saturation state, can be obtained by the scale reading on the collecting cylinder 401; ρ water Is the density of water for precipitation; T is the time it takes for the rainfall to reach saturation; v Total percolation It is the total s...

Abstract

The invention provides a sponge city green land rainwater collecting capability analysis system, which comprises a rainfall simulation device, a rainwater collecting model box, earthwork, a drainage collecting system, a simulation lawn and a moisture test device. The structure is simple; the loading and the unloading are convenient; the system can be tested and used in a room; the simulation experiment workload is reduced. The invention also provides an analysis method, which comprises the flowing steps of configuring earthwork for experiment; filling the rainwater collecting model box with the earthwork; installing the moisture test device and the simulation lawn on the earthwork; monitoring the earthwork moisture content change of each monitoring point in the rainfall process through themoisture test device until all earthwork reaches saturation; calculating the water seepage rate and judging the water seepage capability of the earthwork; stopping rainfall; monitoring the earthworkmoisture content change of each monitoring point in the natural evaporation state; calculating the evaporation rate, and judging the water storage capability of the earthwork. The method has the advantages that the water seepage and water storage capability of the simulation lawn can be relatively accurately analyzed; the sponge city building scheme can be favorably and scientifically drawn up.

Description

Technical field [0001] The invention belongs to the technical field of geotechnical engineering indoor models, and more specifically, relates to an analysis system for rainwater collection capacity of a sponge city green space and an analysis method using the system for analysis. Background technique [0002] In recent years, the concept of "sponge city" has gradually been promoted and applied in modern urban construction and transformation. It is a new generation of urban stormwater management concept, which aims to make cities have a good ability to adapt to environmental changes and deal with natural disasters caused by rainwater. The "elasticity" of China can also be called a "water elastic city". [0003] In the construction of sponge cities, the water absorption, storage and water purification capacity of the green space during rainfall are important research topics. Traditional methods generally use field tests to test, which have a large workload, time-consuming and labor-i...
