[0020] In view of the deficiencies in the prior art, the inventors of the case have long-term research and a large number of practices, and the technical scheme of the utility model is obtained. The technical scheme, its implementation process and principles will be further explained and described as follows.
[0021] For example, Figure 1The utility model discloses a water level test multifunctional device, the water level test multifunctional device, including pipeline 1, connector 2 and water level test subassembly 4, the pipeline 1 is hard pipeline 1, the pipeline 1 can be driven at least in the drive of external force and moves into the soil and extends to the groundwater, the pipeline 1 can be steel pipe or alloy pipeline 1, the pipeline 1 in the embodiment case is steel pipe, when the pipeline 1 needs to move to the soil, generally uses static pressure device to press down the pipeline 1, makes the pipeline 1 move down and extends to the groundwater in the soil.
[0022] The connector 2 is arranged at one end of the pipeline 1, for example Figure 3 The connector 2 includes a plurality of connecting pieces 3, one end of the connecting piece 3 is hinged to the pipeline 1, so that the connecting piece 3 can rotate relative to the pipeline 1, the other end of the connecting piece 3 is a free end, and the free ends of the plurality of connecting pieces 3 converge towards the axial center of the connector 2 during the advancement of the connector 2 in the soil to form an inverted cone shape. Since the connecting pieces 3 are extruded from the side by the soil during movement into the soil, the plurality of connecting pieces 3 converge towards the axial center of the connector 2 during downward movement in the soil, at which time the groundwater cannot or cannot flow into the pipeline 1. During the retraction of the connector 2 in the soil, the free ends of the plurality of connecting pieces 3 separate to allow the groundwater to flow from between the connecting pieces 3 into the pipeline 1. After the pipeline 1 is moved downward to a designated position, the pipeline 1 is pulled upward by a certain height, at which time the connecting pieces 3 are not extruded by the soil, and the plurality of connecting pieces 3 are relatively opened due to their own gravity, thereby allowing the groundwater to flow into the connector 2 and the pipeline 1.
[0023] The water level test subassembly 4 is located in the pipeline 1 during testing, and the water level test subassembly 4 is used at least to measure the water level in the pipeline 1. Specifically, the water level measurement subassembly includes a water level gauge.
[0024] Working principle:
[0025] The pipeline 1 is pressed downward by the static pressure device, and the plurality of connecting pieces 3 converge towards the axial center of the connector 2 due to extrusion by the soil. Under the drive of the static pressure device, the connector 2 and the pipeline 1 move into the soil, and after the connector 2 and the pipeline 1 are moved to a certain depth, the connector 2 and the pipeline 1 are pulled upward by a certain distance, at which time the connecting pieces 3 are not extruded by the soil, and the plurality of connecting pieces 3 are relatively opened, allowing the groundwater to flow into the pipeline 1. The water level test subassembly 4 is hung in the pipeline 1 using a rope or the like, at which time the water level test subassembly 4 can accurately test the water level of the groundwater.
[0026] The application does not need to pre-punch the soil, does not need to fill the clay ball between the hole and the pipeline 1, directly uses the external static pressure device to press the pipeline 1 into the soil, reduces the process, and reduces the cost; because the pipeline 1 extrudes the soil in the process of pressing the pipeline 1 downward, the soil extrudes the pipeline 1 in reaction, so that the extrusion between the pipeline 1 and the soil is very compact, and therefore the application is accurate in measurement, and the inaccuracy caused by the water in the pipeline 1 and the outside water being connected due to the water seepage between the hole and the pipeline 1 is avoided. At the same time, the pipeline 1 in the application can be pulled out and recycled, which further reduces the cost.
[0027] In one embodiment, the pipeline 1 comprises a plurality of longitudinally connected steel pipes, and two adjacent steel pipes are connected by a thread connection. For example, when testing the water level, a pipeline 1 with a length of 10 m is needed, and 10 steel pipes with a length of 1 m can be longitudinally connected together, and two adjacent steel pipes are connected together by a thread connection.
[0028] On the basis of the above, in order to improve the sealing performance of the pipeline 1, sealing oil is applied to the connection between two adjacent steel pipes to seal the pipeline 1 and prevent water from entering the inside of the pipeline 1 from the side of the pipeline 1.

In the process of retreating the connecting head 2 in the soil, the free ends of the plurality of connecting pieces 3 are separated to allow the underground water to flow from between the plurality of connecting pieces 3 into the pipeline 1; the water level testing assembly 4 is located in the pipeline 1 during testing, and the water level testing assembly 4 is used at least for measuring the water level in the pipeline 1. After the pipeline 1 is installed and pulled out for a period of time, the water level is generally measured after standing for 6-8 hours. The water level can be tested in this embodiment whether water flows from the connecting head 2 into the pipeline 1 in the process of moving the pipeline 1 downward, and the device can accurately test the water level.
[0031] Embodiment two:
[0032] The difference between the present embodiment and the embodiment one is that the two adjacent connecting pieces 3 must be in close contact during the process that the pipe 1 is pressed into the soil, so that the water in the soil cannot flow into the pipe 1 from the connecting head 2, and the device can test the permeability coefficient of the underground water, wherein the permeability coefficient k=Q / FI, wherein Q is the amount of water permeated per unit time, F is the total cross-sectional area of the water flow, and I is the hydraulic gradient.
