The specific embodiment
Use the shoe water-stop like water-bearing interval pumping test in Fig. 1, Fig. 2, Fig. 3 and a kind of hydrogeologic prospecting shown in Figure 4; Comprise the pipeline 1 that is installed in the hydrogeological step boring 3; Said pipeline 1 both ends open week side seal; The lower end of said pipeline 1 is provided with the sealing shoe 2 with water barrier 5 height such as grade; Said sealing shoe 2 is positioned on the step 3-1 of hydrogeological step boring 3, and said sealing shoe 2 comprises the multilayer cotton thread 2-1 that is wrapped on pipeline 1 outer surface of tube wall, is coated with pearl oil 2-2 between the adjacent two layers cotton thread 2-1.The aperture of said pipeline 1 is 140mm～170mm, and preferred way is that the aperture of said pipeline 1 is 146mm or 168mm.The height of said sealing shoe 2 is 500mm～1500mm.Said pipeline 1 is processed by seamless steel pipe.Said cotton thread 2-1 is five layers or six layers.
As shown in Figure 3; Hydrogeology step boring 3 is for becoming the boring in aperture; Varying aperture place in hydrogeological step boring 3 forms a step 3-1; Target phase aquifer 6 is positioned at the bottom of hydrogeological step boring 3, and non-target phase aquifer 4 is positioned at the top of hydrogeological step boring 3, is water barrier 5 between target phase aquifer 6 and the non-target phase aquifer 4.
Like Fig. 3 and shown in Figure 4; During use; Water-bearing interval pumping test in this hydrogeologic prospecting is transferred in the hydrogeological step boring 3 with the shoe water-stop, and the attention pipeline 1 that will evenly, slowly sink will write down the length of transferring pipeline 1 in the process of transferring; Sealing shoe 2 is docked with the water barrier 5 at 6 tops, target phase aquifer just, get in the pipeline 1 thereby reach non-target phase aquifer 4 underground water.The stagnant water effect inspection method does; Promptly judge through measuring the inside and outside groundwater level of shoe water-stop; Because the different water cut layer has different Hydraulic Power Systems, formed each aquifer naturally and had separately water level elevation (be reflected as in the boring depth to water-be the degree of depth of water level) to ground.If the target phase aquifer water level 7 in the pipeline 1 is identical with pipeline 1 non-target phase aquifer water level 8 outward, then stagnant water effect difference or failure.If the target phase aquifer water level 7 in the pipeline 1 has the discrepancy in elevation, then sealing success with pipeline 1 outer non-target phase aquifer water level 8.
The utility model can effectively stop the water in non-target phase aquifer 4 to infiltrate in the target phase aquifer 6, thereby effectively prevent the hydraulic connection between non-target phase aquifer 4 and the target phase aquifer 6 through pipeline 1 being set and being positioned at the sealing shoe 2 on the pipeline 1; The water-bearing interval pumping test is simple in structure with the shoe water-stop in the hydrogeologic prospecting, novel and reasonable design, and functional reliability is high; Long service life; Stagnant water effect is good, and is simple in structure, easy to use; Cost of production is low, is convenient to promote the use of.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
