Specifically, any three adjacent leaching pits 201 in the leaching pit unit 2 are distributed in a delta shape, so that the interception effect can be improved.
In an embodiment, the rinsing pit 3 is semicircular, the depth of the rinsing pit 3 is 7-9cm, and the diameter of the rinsing pit is 18-22cm, so that water storage can be fully finished on the basis of no collapse.
In one embodiment, the depth of the rinsing groove 3 is 7-9cm, and the width of the groove is 15cm.
The following is directed to the slope of this application for simulation detection, and the specific mode is as follows:
(1) Filling soil tank
Removing impurities such as stones and plant roots from the collected soil, naturally air-drying, and sieving the soil for later use. Fine sand is paved at the bottom of the steel tank to simulate the water permeability of a natural slope, the fine sand and the soil are separated by two layers of gauze so as to prevent test soil from flowing out from small gaps at the bottom, the soil is paved layer by layer on the gauze, the compaction of the side wall is particularly noted, the influence of the side wall effect on the test result is prevented, and 6 layers are paved in total. After the soil is filled for a period of time, sprinkling water to the soil tank during the period, and keeping the water content of the soil at 10% -15%, so as to simulate the soil quality of coastal beach areas as much as possible.
(2) Test group treatment
The method comprises the steps of correspondingly processing soil groove slopes of each group, covering salina resistant grass, setting bare slope processing of comparison groups, and selecting three comparison groups (one slope processed by the method and one bare slope covered by the salina resistant grass in each comparison group) according to the multi-year rainfall characteristics of a test area, wherein the three rainfall intensities of 50mm/h, 100mm/h and 150mm/h are selected for artificial rainfall tests according to the multi-year rainfall characteristics of the test area; specifically, control group 1: stopping rainfall after the slope is produced for 60min under the condition of 50 mm/rainfall: control group 2: stopping rainfall after the slope under the rain intensity of 100mm/h produces the flow for 30 min; control group 3: and stopping rainfall after the slope with the rain intensity of 150mm/h flows for 30 min.
(3) Comparison analysis
At 50 mm/rainfall intensity:
initial runoff time of bare slope, slope of the application pattern and salt-tolerant grass covered is 82.70min, 120.87min and 63.35min respectively; compared with a bare slope, the initial flow time of the slope surface of the pattern of the application is respectively delayed by 38.17min, and the flow delay effect is respectively 46.2%. The halograss-tolerant coating is advanced by 19.35min, and the yield is advanced by 23.4%. The analysis is that although the salt-tolerant grass coating can intercept rainfall, grass roots play a role in fixing the silty and mucky soil slope, meanwhile, the soil infiltration rate is weakened, and the runoff is accelerated. The grass cover proposed on loess and Huang Jun (2010) can optimize the soil structure and increase capillary pore channels for infiltration, so that the conclusion of the increase of rainfall infiltration is different, and the grass cover is mainly due to loose structure and strong water permeability of coastal beach silt soil, and growth of grass roots can weaken the slope water permeability. Thus, if plant measures can grow on the sea-going slope, the effect of the plant measures on soil fixation is obvious, but the plant measures also lead to earlier runoff time.
At a rainfall intensity of 100 mm/h:
initial flow time of bare slope, slope of the application pattern and salina-resistant grass cover is 30.25min, 42.63min and 36.20min respectively, and compared with bare slope, slope of the application pattern and salina-resistant grass cover
The initial flow time of the coverage is respectively delayed by 12.38min and 5.95min, and the flow delay effects are respectively
40.9% and 19.7%. The effect of delaying the flow of the slope of the pattern is basically unchanged under the strong rain, and the salina-resistant grass coverage is also changed from the early flow of the rain with the strength of 50mm/h to the delayed flow of the rain with the strength of the rain, because the impact force of the rain drops is increased along with the increase of the strength of the rain, and the effect of weakening the rain drops to splash by grass is more prominent.
At a rainfall intensity of 150 mm/h:
initial runoff time of the bare slope, the slope of the application pattern and the salicornia oleifera cover are 2.17min, 5.58min and 5.17min respectively, and compared with the bare slope, the slope of the application pattern and the salicornia oleifera cover delay 3.41min and 3.00min respectively, and the runoff delay effect is 157.1% and 138.3% respectively. As the rain intensity is further increased, the initial flow time is greatly advanced compared with the rain intensity of 100mm/h, the flow delay time is shortened, but the flow delay effect of several regulation measures is greatly improved, wherein the initial flow time of the slope of the pattern of the application reaches more than three times of that of the bare slope. The initial flow is advanced along with the increase of the rain intensity in the stage, but the flow delaying effect of the measures is improved relative to that of a bare slope.
It follows that the slope of the pattern of the present application is more suitable for use as a shoal slope to delay the initial flow time.
