[0019] See Figure 1 .

[0020] This utility model discloses a hydrological well integrated specimen, including a cylindrical body 1 with one end open. The open part of the cylindrical body 1 is connected to the hydrological well. The connection between the cylindrical body 1 and the hydrological well is sealed. A water outlet 11 is provided on one side of the cylindrical body 1 and a water outlet valve 12 is provided that can open and close the water outlet 11.

[0021] The cylinder body 1 is provided with a pressure gauge 2 for detecting the pressure in the cylinder body 1.

[0022] In the implementation, when collecting data, the water outlet valve 12 is opened, and a fixed container is used to measure the water volume in the hydrological hole by taking multiple average values to obtain the water volume, and then the water flow velocity is calculated; the water outlet valve 12 is closed, and the water pressure data in the hydrological hole can be obtained by observing the pressure value on the pressure gauge 2.

[0023] It should be pointed out that the hydrological hole is used for observing whether the freezing wall of the shaft is closed (it is necessary to collect various data at different times multiple times, not just once), and in the construction of the shaft freezing curtain, water in the water-bearing stratum will flow to the ground along the hydrological hole under the pressure of the freezing curtain. During the observation of the construction process, the pressure and flow rate of the water flowing to the ground can provide strong support for the decision and analysis of the shaft freezing closing.

[0024] In addition, it should be pointed out that the hydrological hole is formed by cutting off the top of the frozen pipe during construction, so the hole wall of the hydrological hole is a metal pipe, and the cylinder body 1 can be welded on it.

[0025] The present application can measure multiple data at one time without replacing the test piece, enhances the accuracy and comprehensiveness of data collection, ensures that multiple key parameter data can be obtained at one time, obtains multiple data in a short time, has high timeliness and small deviation, simplifies the test process, and reduces the test operation difficulty and human error.

[0026] It should be pointed out that the cylinder body 1 can also be a pipe, and when the cylinder body 1 is a pipe, a cover can be arranged at the top of the hydrological hole, and then one end of the cylinder body 1 penetrates through the cover and communicates with the hydrological hole and sealingly cooperates with the cover.

[0027] In an embodiment, the cylinder body 1 is further provided with a thermometer 3 for measuring the water temperature in the cylinder body 1 in real time. This design further expands the types of measured data, which is helpful for judging whether the freezing wall of the shaft is closed.

[0028] The temperature measuring end of the thermometer 3 can be in the cylinder body 1 or at the water outlet 11.

[0029] In an embodiment, the pressure gauge 2 communicates with the top of the cylinder body 1 through a connecting pipe 21, and the connecting pipe 21 is provided with a pressure valve 22 for controlling the on-off between the pressure gauge 2 and the cylinder body 1. In this way, the pressure valve 22 is arranged, on the one hand, the pressure gauge 2 can be replaced when it is damaged; on the other hand, the pressure gauge 2 can also be prevented from being in a pressure state for a long time, the sensitivity of the pressure gauge 2 is guaranteed, and the pressure gauge 2 is convenient for calibration.

[0030] In an embodiment, the bottom of the barrel 1 is provided with a connecting barrel 4 for sealing connection with the orifice of the hydrological hole, the outer side of the barrel 1 is provided with an outer thread, the inner side of the connecting barrel 4 is provided with an inner thread matched with the outer thread, and one end of the barrel 1 is screwed into the connecting barrel 4.

[0031] In a specific implementation, the inner and outer threads are matched with pipe threads to realize sealing, the end of the connecting barrel 4 away from the barrel 1 is sealingly connected with the orifice of the hydrological hole by welding, and the height of the water outlet 11 on the barrel 1 can be adjusted by rotating the barrel 1, so that the heights of the water outlets 11 of the barrels 1 are consistent, which is beneficial to the accuracy of measurement data.

[0032] In an embodiment, the barrel 1 is provided with a nut 5 matched with the outer thread on the barrel 1, and the nut 5 is used to cooperate with the connecting barrel 4 to fix the position of the barrel 1 relative to the connecting barrel 4. In a specific implementation, the nut 5 is rotated to move the nut 5 towards the connecting barrel 4, until the nut 5 contacts the connecting barrel 4, and then the nut 5 is continuously rotated to generate a pre-tightening force on the thread on the nut 5, the outer thread and the inner thread, so as to lock the position of the barrel 1 relative to the connecting barrel 4.

[0033] In the working process of the utility model, the end of the connecting barrel away from the barrel is sealingly connected with the orifice of the hydrological hole by welding, then the barrel is rotated to adjust the height of the water outlet on the barrel, so that the heights of the water outlets on the barrels are consistent, then the position of the barrel relative to the connecting barrel is locked by the nut, and then relevant experimental work is carried out.

[0034] The utility model has good advantages in improving test efficiency and reducing test cost. On the one hand, the cost of human resources and equipment loss caused by frequent replacement and installation of different test pieces in traditional tests is reduced. On the other hand, the monitoring frequency efficiency is increased due to the improvement of test efficiency, so that more diversified data is obtained. These data can accurately reflect the water pressure and water temperature conditions, and provide strong support for well freezing circle decision and analysis. Moreover, this achievement can be repeatedly used in other projects, and can be modified by using waste pressing parts, so that the waste utilization value and economic benefits are improved, resource waste is avoided, and the utility model can be widely used.
