Specifically, the length of the second casing 3 is set according to the depth of the soil stratum, for example, the second casing can be located at the junction position of clay sandwiched gravel and fully weathered granite amphibole and the crack aquifer of the strongly weathered and weathered granite amphibole.
The fixed pipe sealing component 4 is arranged at one end of the second layer sleeve 3 at the junction.
The water seepage flower pipe 5 is arranged at the lower end of the second-layer sleeve 3, and the water seepage flower pipe 5 is partially inserted into the second-layer sleeve 3. In addition, the pipe fixing sealing member 4 is disposed between the second sleeve 3 and the water seepage flower pipe 5, for preventing water seepage from flowing out, and for example, a clay material with poor permeability may be used for sealing. The function of the orifice sleeve 2 and the second sleeve 3 is to ensure that soil particles do not enter the pumping well to cause sedimentation, so that long-term stable operation of the pumping pump 6 described below is ensured.
The upper end of the water seepage flower pipe 5 is positioned on the strong weathered and medium weathered granite flash rock crack aquifer, and the water seepage flower pipe 5 is vertically paved along the well wall direction. And, there are infiltration holes on the pipe wall of infiltration flowtube 5, this infiltration hole can be round hole or the equidistant hole of bar, and its effect is collected groundwater in the water-containing layer to prevent debris such as sand and stone from getting into the well. The water suction pump 6 is provided in the water seepage pipe 5.

The acid groundwater in the downstream of the reservoir is collected by the water suction pump 6 and then is conveyed into an upstream water blocking dam or directly conveyed to a surface water treatment plant.
As shown in fig. 2, the well head position setting schematic diagram of the acid water in the dumping site according to the invention comprises an intercepting pumping well 20 and a water quality observation well 30, wherein the intercepting pumping well 20 is positioned at the downstream of a water blocking dam, the water quality observation well 30 is arranged at the downstream of the intercepting pumping well 20, and the water quality observation well 30 is consistent with the overall structural design of the intercepting pumping well 20.
The method for collecting acidic water in a dump according to the present invention will be described with reference to fig. 3.
Fig. 3 is a flowchart of a method for collecting acid water in a dump according to the present invention. The collecting method is implemented by using the above-described intercepting pumping well 20 and water quality observation well 30, and the detailed structure of the well will not be repeated.
First, if the underground water quality downstream of the dump is contaminated through investigation or prediction, a dam is provided on the surface of the dump to intercept the surface acid water once, and the acid water on the surface is controlled to be prevented from flowing into the nearby river 10 or stream in step S110.
Then, in step S120, due to the penetration of the earth surface, part of the acidic water permeates into the ground and is mixed with the underground water, so that a plurality of intercepting pumping wells 20 are arranged along the river channel in the downstream topography of the retaining dam, so that the part permeated into the underground water is subjected to secondary interception of the acidic water under the collection of the intercepting pumping wells 20, and the polluted underground water is not continuously diffused to the downstream of the river channel after being intercepted by the intercepting pumping wells 20. In particular, the intercepting pumping wells 20 can be controlled to be spaced at intervals of 30 m-50 m according to the topographic conditions, and the intervals between the wells can be determined to have mutual influence ranges through on-site pumping tests in order to reduce the pumping interference degree between the wells, which will not be described in detail herein.
Then, in step S130, the extracted acidic groundwater is returned to the upstream barrage or directly sent to the surface water treatment plant through a pipe connection by a suction pump 6 in the intercepting suction well 20, as described in fig. 1.
Finally, in step S140, the water quality observation well 30 is disposed downstream of the intercepting pumping well 20 for checking the intercepting effect of the intercepting pumping well 20. Through in the water quality observation well 30, the water pump 6 pumps the water in the water quality observation well 30, and tests the pH value of the water quality by a modern test means to determine whether the water quality is acidic water, if it is detected that the underground water quality is still abnormal, it is indicated that the number of the intercepting pumping wells 20 is insufficient, the underground secondary interception of the acidic water cannot be satisfied, and the effect is improved by properly increasing the number of the intercepting pumping wells 20.
Next, the specific arrangement position of the intercepting pumping well 20 in step S120 is described in a supplementary manner, and two arrangement methods are provided according to the actual situation on site:
1. when the horizontal underground hydraulic gradient of each ditch in the dumping site is steep, the underground water mainly flows to the ditches from the two sides of the ditches, so that the cut-seepage pumping well 20 is arranged in the ditches in sequence to obtain better effect.
2. When the horizontal hydraulic gradient of the downstream ditch of the water retaining dam is slower, three water intercepting pumping wells 20 are arranged in a horizontal arrangement mode so as to enlarge the water intercepting area, and the underground polluted water is effectively intercepted.
As described above, the method for collecting the acid water in the dumping site has the advantages of low investment, easy implementation on the ground surface, convenient construction and very convenient and fast detection and treatment of the acid water.
