Embodiment 1
[0041] This embodiment provides an island and reef underground freshwater simulation device, please refer to figure 1 , figure 2 , image 3 as well as Figure 4 , this island and reef underground freshwater simulation device includes:
[0043] The seepage experimental mechanism, the seepage experimental mechanism includes a first space 11 and a second space 13, the first space 11 and the second space 13 are spaced apart, the first space 11 and the second space 13 are connected by a seepage flow hole 15, the second The space 13 communicates with a first inflow port 17 and a first outflow port 18;
[0044] The environmental liquid circulation mechanism 8 has a second inflow port 21 and a second outflow port 20 on the environmental liquid circulation mechanism 8, the second inflow port 21 communicates with the first outflow port 18, the second outflow port 20 communicates with ...
Embodiment 2
[0079] This embodiment provides a method for simulating underground fresh water on islands and reefs. This method for simulating underground fresh water on islands and reefs uses the device for simulating underground fresh water on islands and reefs provided in Embodiment 1, and includes the following steps:
[0080] Fully wash the soil sample with pure water to remove the original electrolyte in the soil, then dry, sieve and mix;
[0081] Specifically, after sufficient rinsing, the electrolyte content and electrical conductivity of the exudate after pure water seepage in the soil sample are extremely low, and the leaching soil sample is dried in the shade, and the soil compaction part is crushed and sieved Divide, and mix.
[0082] Filling the pretreated soil in layers into the first space 11, and setting detection mechanisms at different heights of the first space 11 during the filling process;
[0083] Specifically, the soil samples are loaded into the first space 11 secti...

Abstract
The invention provides an island underground freshwater simulation device and method and belongs to the field of freshwater resource utilization. The island underground freshwater simulation device comprises a precipitation mechanism which is used for simulating precipitation of a natural environment, a seepage experiment mechanism which comprises a first space and a second space, an environment liquid circulation mechanism which is provided with a second inflow hole and a second outflow hole and is used for providing a circulating water flow for the interior of the second space, and a detection mechanism which is used for detecting the salt content in the first space; the second space communicates with a first inflow hole and a first outflow hole. The island underground freshwater simulation device and method can conveniently simulate the condition of island underground freshwater and is beneficial to performing a test.
Description
technical field [0001] The invention relates to the field of utilization of fresh water resources, in particular to an island and reef underground fresh water simulation device and method. Background technique [0002] Small coral islands often lack fresh water resources that can be directly used. The main source of domestic water is to store and collect rainwater. In some cases, groundwater can be extracted. In the process of development and utilization of islands and reefs, fresh water resources are the most critical to determine their carrying capacity. factor. Under normal conditions, a freshwater aquifer in the shape of a lens is formed in the naturally formed island strata, which is called a "freshwater lens". The maintenance and utilization of freshwater lenses is a key factor in the development of islands and reefs. [0003] The depth of the freshwater lens shape of a single specific island reef is closely related to the soil properties, temperature, precipitation ...
