Problems solved by technology

[0003] From the "Application of Value Engineering Theory in Engineering Design" written by Ren Changneng, etc., we know that value engineering theory has been widely used in the field of engineering design, but when it comes to specific applications in individual specialized fields, the determination of specific functions and costs is difficult. There are big differences, and there is still a big gap in the recent emerging "sponge city construction"

Embodiment 1

[0036] A method for evaluating groundwater replenishment capacity, comprising the following steps:

[0037] 1) Measure the maximum water depth L of the facility to be evaluated after the rainstorm, the unit is cm;

[0038] 2) The bottom of the facility is provided with a substrate; measure the stable penetration rate K of the substrate, in mm / min;

[0039] The substrates include impermeable substrates and soil-based substrates. For impermeable substrates, K=0mm / min; for soil-based substrates, use a soil-boring ring knife to sample to test the stable infiltration rate;

[0040] 3) Supplementary capacity evaluation: the runoff infiltration capacity coefficient d=L×K of the facility to be evaluated;

[0041] Among them, when d=0, the groundwater replenishment ability is poor, and the evaluation grade is 0; when 020, the groundwater replenishment ability is strong, and the evaluation level is 3.

[0042] In this Example 1, the maximum ponding depth is the maximum ponding depth t...

Abstract

The present invention provides a groundwater recharge capacity evaluation method which comprises the steps of (1) measuring the maximum water depth L of a facility to be evaluated after a rainstorm, (2) measuring the stable permeation rate K of the substrate of the facility, wherein, for an impermeable substrate, K=0, for a soil substrate, the stable permeation rate is tested by using soil taking ring knife sampling, (3) evaluating recharge capacity, the runoff infiltration capacity coefficient d of the facility to be evaluated satisfies a formula d=L*K, wherein, when d is 0, the groundwater recharge capacity is poor, when d is larger than 0 and is smaller than or equal to 10, the groundwater recharge capacity is weak, when d is larger than 10 and is smaller than or equal to 20, the groundwater recharge capacity is medium, and when d is larger than 20, the groundwater recharge capacity is strong. The groundwater recharge capacity evaluation method is used for rapidly evaluating the groundwater recharge capacity in a sponge city design process so as to realize the design of a sustainable development sponge city or implement remedial measures conveniently and timely.

Description

technical field [0001] The invention relates to the technical field of value engineering, in particular to a method for evaluating groundwater replenishment capacity. Background technique [0002] The Sponge City Construction Technical Guidelines issued by the Ministry of Housing and Urban-Rural Development in 2014 put forward basic principles for the construction of rainwater systems for low-impact development. It has great guiding significance for the implementation of technical measures, but the understanding of the impact of its cost factors is still insufficient, and the evaluation of technical measures is still only in the aspect of function. The low-impact development of stormwater systems is at the heart of the proposed technology for sponge cities. [0003] From the "Application of Value Engineering Theory in Engineering Design" written by Ren Changneng et al., we know that value engineering theory has been widely used in the field of engineering design, but for sp...
