Embodiment 1

[0048] A method for determining the construction location of a karst slope water storage project, the steps of which are:

[0049] 1. Set up the surface runoff test area.

[0050] Select the test points in the area where the karst slope water storage project is planned to be built. The selection of the test points refers to the Water Conservancy Industry Standard of the People's Republic of China: Technical Specifications for Soil and Water Conservation of Water Conservancy and Hydropower Engineering (SL575-2012), and the selected test points can reflect the quality of the area. Typical land use types and soil and rock distribution characteristics. On this basis, according to the surface undulation of the test point and the distribution characteristics of soil and rock, the boundary of the runoff area of ​​the test point is determined. In this embodiment, the final area of ​​the runoff area is 10m 2 , whose area is the area covered by the simulated raindrop generator (nozzle ...

Embodiment 2

[0070] A device for determining the construction location of a karst slope water storage project, including a simulated raindrop generator 1 and a surface runoff test area 2;

[0071] The device described in this example is used for the evaluation of the construction location of the karst slope water storage project in Example 1.

[0072] The surface runoff test area 2 is located within the rainfall coverage area generated by the simulated raindrop generator 1 .

[0073] The simulated raindrop generator 1 consists of a water inlet hose 1-1, a water meter 1-2, a gate valve 1-3, a D32 stainless steel branch pipe 1-4, a water pressure gauge 1-5, a D32 stainless steel main pipe 1-6, and a camera 1- 7. Equal diameter tee 1-8, first equal diameter tee 1-9-1, second equal diameter tee 1-9-2, first 90 degree elbow 1-10-1, second 90 degree Elbow 1-10-2, third 90-degree elbow 1-10-3, fourth 90-degree elbow 1-10-4, first copper cock 1-11-1, second copper cock 1-11-2, the third copper c...

Abstract

The invention discloses a method and a device for determining a construction position of a water storage project on a Karst slope. By adopting the method provided by the invention, key hydrological parameters such as initial runoff producing time, initial runoff producing rainfall and stable infiltration rate of the slope of a tested area, and the problem of accurately and quantitatively obtaining the hydrological parameters of the Karst slope on a field scale is solved; By adopting field in-situ non-disturbance hydrological parameter testing method, the destruction of soil and rock structures can be minimized and the hydrological parameter results are guaranteed to be true and reliable; the provided device is simple to manufacture, the investment is small, the device is convenient to carry and install, and the actual demand for related devices for evaluating the suitability of the construction position of the slope water storage project in the Karst area is satisfied.

Description

technical field [0001] The invention belongs to the field of agricultural water and soil engineering, and more specifically relates to a method for determining the construction location of a karst slope water storage project, and also relates to a device for determining the construction location of a karst slope water storage project. The method or device described in the present invention is suitable for directly It guides the production practice of efficient use of limited water resources in karst arid areas, and is suitable for scientific research and livelihood services such as geological surveys, farmland water conservancy, and vegetation restoration and reconstruction. Background technique [0002] The karst area accounts for 15% of the world's land area and provides water for 25% of the population. my country has the widest distribution and largest area of ​​karst (3.443 million km 2 ) of the country, accounting for 1 / 3 of the land area. Southwest (about 540,000 km ...
