Problems solved by technology

The water-soil mismatch pattern of "soil is upstairs and water is downstairs" has led to two major problems in the current storage model of slope water resources in this area: the surface runoff on the slope is small, and there is no adjustable water on the surface; Time-consuming and costly
Therefore, in view of the above problems, the present invention proposes a low-cost, simple and easy-to-use method for efficient collection of rock-soil interface flow in karst areas, which alleviates or overcomes the technical problems of adjustable surface waterlessness and high cost of groundwater exploitation in this area.

Embodiment 1

[0027] A method for efficiently collecting rock-soil interface flow in karst areas, the steps of which are:

[0028] A. The soil layer of the karst slope is shallow, and the thickness of the soil layer can be estimated with a simple measuring drill. A simple measuring drill can be made of multiple (9) thick steel bars with a length of about 30 to 40 cm. The downhill slope is divided into upper, middle, lower, left, middle, right, vertical and horizontal rows at intervals of 60cm. Insert the soil layer until the bottom rock, mark the depth of the probe insertion into the soil layer with a watercolor pen, then pull out the probe and measure it with a measuring ruler Insert the depth of the soil and record it. In this way, the approximate thickness distribution of the soil layer can be obtained. Find the deepest position of the drill bit insertion depth, and you can find a slope where the downhill position is relatively thicker than the soil layer (measurement record with the rule...

Embodiment 2

[0037] The applicant designed a field experiment according to the method of Example 1, and the calculation results obtained according to the prediction equation (3) are shown in Table 1.

[0038] Table 1 Test data

[0039]

[0040] Note: k is calculated in the table * , n is the empirical coefficient, k * The value is 2.0057m / h, and the value of n is 2.73.

[0041] According to the local topographical conditions, areas with slopes of 5°, 10°, 15°, 20°, and 25° and soil depths of about 0.05m, 0.1m, 0.15m, 0.2m, 0.25m, and 0.3m were selected. as a field test site. It can be seen from the table that under the same slope, the thicker the soil layer, the greater the instantaneous runoff production. When the slope is 5°, the instantaneous runoff production at the depth of 0.3m is 0.00052543m 3 / h, far greater than the depth of the soil layer of 0.05m, the flow rate is 0.00000066m 3 / h. Under the same thickness of soil layer, the greater the slope, the greater the instantane...

Embodiment 3

[0044] according to figure 1 , figure 2 It can be seen that a device for efficiently collecting rock-soil interface flow in karst areas consists of soil layer 1, rock layer 2, rock-soil interface 3, rock-soil interface flow 4, downhill position 5, surrounding water stalk 6, gauze 7, Composed of cement mortar 8, soft filled gauze large-hole PVC pipe 9, silicone glue 10, and water storage tank 11, it is characterized in that: the upper layer of the rock-soil interface 3 is the soil layer 1 and the lower layer is the rock layer 2, and in the rock-soil interface 3 There is a rock-soil interface flow 4, there is a downslope 5 between the soil layer 1 and the rock layer 2 and the rock-soil interface 3, the rock-soil interface 3 is connected to the gauze 7, the surrounding water stem 6 is connected to the cement mortar 8, and the soft filling The large-hole PVC pipe 9 of the gauze is connected to the surrounding water stalk 6 and the water storage tank 11 respectively, and the larg...

Abstract

The invention discloses a method and a device for efficiently collecting karst region rock-soil interface water flow. The method comprises the following steps of: (1) thickness distribution of soil isdetected by using a marking pin: the marking pin is made of a steel bar, and is inserted into a underlying bedrock; the insertion depth of a soil layer is marked by a water color pen; and then a place where a slope surface is thicker relative to the soil layer is found by measuring the insertion depth using a measuring tape; 2) an equation for calculatinginstantaneous water flow potential at a rock-soil interface is predicted: the soil layer is in direct contact with a rock layer to form a rock-soil interface; a water flow at the rock-soil interface comes from gravity water flowing at the slope surface in the lateral direction, the rock-soil interface is connected with a gauze; a water-surrounding weiris connected with cement mortar; and a PVC pipe is separately connected with the water-surrounding weirand awater storage tank. According to the method and the device for efficiently collecting a karst region rock-soil interface water flow, the instantaneous water flow size atthe rock-soil interface ofa certain karst slope is obtained through a water flow potential prediction equation, so that the best position for building a rock-soil interface water flow collection device is determined. The method is easy to implement, and the operation is simple and efficient.

Description

technical field [0001] The invention belongs to the fields of hydrology, ecology, soil erosion and soil and water conservation, and more specifically relates to a method for efficiently collecting rock-soil interface flow in karst areas, and also relates to a device for efficiently collecting rock-soil interface flow in karst areas. Guide the production practice of efficient use of limited water resources in karst areas, and alleviate the problems of engineering water shortage and drought in karst areas. Background technique [0002] Although the southwest karst area has abundant rainfall, due to the shallow soil layer and strong rock seepage, the hydrological process is rapid, the surface water leaks a lot, the groundwater is deeply buried, and the karst drought and lowland waterlogging occur frequently. Therefore, understanding the hydrological process in the karst region and developing a model for efficient regulation and storage of water resources is the key to achieving...
