Description

Technical Field

[0001] The utility model relates to the technical field of devices for horizontal holes, and more specifically to a device for long-term sequential online monitoring of horizontal monitoring holes. Background Art

[0002] Horizontal monitoring holes are relatively common in hydrogeological surveys and geological surveys. For example, in the surveys before the tunnel design and construction of pipeline projects such as water diversion projects, highways, and railways, horizontal or near-horizontal surveys along the tunnel axis are more effective and economical than conventional vertical hole surveys for exploring the engineering geological conditions along the tunnel. During the later tunnel excavation, water inrush is likely to occur, and the exploration holes above the tunnel are often left as monitoring holes for long-term water level and water quality monitoring, which can play a reference role in the analysis of water inrush at each mileage section during the later construction process.

[0003] Online automatic monitoring of water level and water quality is mostly applied in vertical shafts or inclined shafts. Since the water in the horizontal monitoring holes will continuously gush out of the holes, there is little online automatic monitoring of the water level and water quality in the horizontal monitoring holes. Currently, the automated monitoring that can be collected is mostly for the monitoring of the structure of the horizontal monitoring holes themselves during the exploration process, or for the monitoring of the horizontal directional drilling process. There is little involvement in the monitoring of the water level and water quality in the horizontal monitoring holes. This is because the inside of the horizontal monitoring hole is at the same height as the hole opening, and the well water can be directly discharged out of the hole, and it is difficult for the water volume in the hole to reach the water volume required for effective monitoring by the probe. If the hole opening of the monitoring hole is blocked and the probe is pre-buried, theoretically, the monitoring of the water level and water quality in the hole can be achieved. However, once the probe fails, it is very difficult to replace, and it cannot effectively ensure the long-term sequential online monitoring of the water level and water quality in the horizontal monitoring holes.

[0029] The following will be combined with Figures 1 - 3 , and a device for long-time sequential online monitoring of the length of a horizontal monitoring hole involved in the embodiments of the present application will be described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation to the present application.

[0030] Embodiment 1:

[0031] As Figures 1 - 3 shown, a device for long-time sequential online monitoring of the length of a horizontal monitoring hole 11 includes: a cavity, a ball valve unit, a pre-buried transmission line 8, and a probe 7. The cavity includes an installation part 2 and a tubular part 3 that communicate with each other; the tubular part 3 is fixed in the horizontal monitoring hole 11; the cavity involved is made of wire mesh skeleton polyethylene (PE) composite material with strong axial pressure-bearing capacity, and is divided into an in-hole tubular part 3 and an out-of-hole installation part 2. The wall thickness of the in-hole tubular part 3 is 2 mm, and the outer diameter depends on the aperture size, generally 10 mm smaller than the aperture of the horizontal monitoring hole 11, that is, the distance between the tubular part 3 of the cavity and the hole wall is 5 mm. It is used to fill the adhesive.

[0032] In some embodiments, the diameter of the tubular part 3 is smaller than the diameter of the horizontal monitoring hole 11, a blocking ring is provided at the end of the tubular part 3, and the sum of the height value of the blocking ring and the diameter of the tubular part is larger than the diameter of the horizontal monitoring hole 11; the gap between the tubular part 3 and the horizontal monitoring hole 11 is fixed by filling with an adhesive. The blocking ring generally uses a rubber 10 ring. Under the action of friction, the rubber 10 bends and fills the gap between the device and the hole wall. Due to the high elasticity of the rubber 10, the rubber 10 ring can form a relatively closed interval, so that the water in the horizontal monitoring hole 11 no longer enters the gap between the device and the hole wall, providing a condensation space and time for the adhesive to fill the remaining gap section. The adhesive in this embodiment is cement 9.

[0033] The ball valve unit is arranged in the installation part 2, and the ball valve unit is used to connect or disconnect the installation part 2 and the tubular part 3; the ball valve unit includes a valve seat 4 and a ball valve sphere 6. The valve seat 4 is arranged in the installation part 2, and the ball valve sphere 6 is arranged in the valve seat 4; a wrench 1 for driving the rotation of the ball valve sphere 6 penetrates through the installation part 2 and is connected to the ball valve sphere 6.

[0034] The ball valve sphere 6 involved in the present utility model is spherical, with the sphere diameter being the same as the inner diameter of the tubular part 3 of the cavity. The center of the sphere is located at a position above the axis of the tubular part 3 of the cavity. The wrench 1 involved in the present utility model passes through the cavity and is directly connected to the ball valve sphere 6. The length of the wrench 1 is the same as the diameter of the ball valve sphere 6. The opening and closing angle of the wrench 1 is 90°. For convenient opening and closing, the outer end of the wrench 1 is slightly raised by an angle of 10°.

[0035] The embedded transmission line 8 is arranged in the tubular part 3 through the installation part 2. The probe 7 is arranged in the tubular part 3 and is connected to the embedded transmission line 8.

[0036] The embedded transmission line 8 and the installation part 2 are hermetically and fixedly connected. The length of the embedded transmission line 8 extending out of the installation part 2 is not less than 3 times the length of the monitoring probe 7. Only in this way can there be sufficient margin for taking and placing the probe 7 when replacing or repairing the probe 7. The embedded transmission line 8 and the probe 7 are connected through the quick-connect interface 5. The quick-connect interface 5 includes a quick-connect male head and a quick-connect female head. The quick-connect female head is arranged at the probe 7 end, and the quick-connect male head is arranged on the embedded transmission line 8.

[0037] In some embodiments, the probe 7 involved in the present utility model can be various types of monitoring probes 7. The maximum outer diameter of the probe 7 is determined according to the inner diameter of the tubular part 3 of the cavity, generally not greater than 1 / 4 of the inner diameter.

[0038] When the present utility model is in use, only the device needs to be horizontally pushed into the horizontal monitoring hole. Cement and other cementitious materials are used to fill the pores between the hole wall and the cavity. Finally, the required probe can be placed. Specifically, one side of the tubular part of the device is horizontally pushed into the horizontal monitoring hole. The rubber at the end of the tubular part bends and fills the gap between the device and the hole wall under the action of friction. Due to the high elasticity of the rubber, the rubber filling section can form a relatively closed interval, preventing the water in the hole from entering the gap between the device and the hole wall, providing a setting space and time for cement and other cementitious materials to fill the remaining gap section. Cement and other cementitious materials are poured into the hole from the hole opening. After complete solidification, the embedded transmission line is pulled out from the cavity of the ball valve sphere with tools, and the quick-connect female head of the probe is docked with the quick-connect male head of the embedded transmission line to complete the connection between the probe and the transmission line. After the probe parameters are set, the tool is used to horizontally place the probe in the tubular part of the cavity from the cavity of the ball valve sphere. Rotate the wrench 90° clockwise to close the ball valve, and the installation of the entire device and the probe is completed. If it is necessary to repair or replace the probe, rotate the wrench 90° counterclockwise to open the ball valve, take out the probe in the device according to the foregoing steps to complete the repair or replacement, and then put it back.

[0039] Next, the detailed implementation examples of the present device will be elaborated by taking the application in a 75mm horizontal monitoring hole as an example.

[0043] Step 3: Pump quick-setting cement into the 5-mm gap between the cavity and the hole wall from the hole opening. After filling, seal it at the hole opening with a template until the cement completely solidifies, and then remove the template.

[0044] Step 4: Rotate the handle to rotate the ball valve with a ball diameter of 61 mm to the open state. After opening, the maximum circumscribed diameter of the irregular gap formed by the ball valve and the tubular part of the cavity is 54 mm.

[0045] Step 5: Use a hooked tool to hook out the embedded transmission line with a diameter of 5 mm and a length of 500 mm from the cavity of the ball valve outside the device.

[0046] Step 6: Connect the quick-connect female head of the cylindrical water level and water quality monitoring probe with a diameter of 18 mm and a length of 150 mm to the quick-connect male head of the embedded transmission line.

[0047] Step 7: Set the sensor parameters and finish the debugging.

[0048] Step 8: Horizontally place the probe sensor end into the tubular part of the cavity facing the horizontal monitoring hole, and use a tool to push the probe into the hole to straighten the monitoring transmission line of the device.

[0049] Step 9: Rotate the handle to rotate the ball valve to the closed state.

[0050] The equipment installation process is completed.

[0051] If it is necessary to repair or replace the probe during the process, the following steps can be carried out:

[0052] Step 10: Rotate the handle to rotate the ball valve to the open state.

[0053] Step 11: Use a hooked tool to hook out the embedded transmission line from the cavity of the ball valve outside the device.

[0054] Step 12: Disconnect the monitoring probe from the embedded transmission line at the quick-connect interface.

[0055] Step 13: Repair the probe or replace the probe.

[0056] Step 14: Connect the quick-connect female head of the repaired or replaced probe to the quick-connect male head of the embedded transmission line.

[0057] Step 15: Confirm the sensor parameters and complete the debugging;

[0058] Step 16: Horizontally place the probe sensor end towards the monitoring hole into the cavity tubular section, and use a tool to push the probe into the hole, keeping the device monitoring transmission line straightened;

[0059] Step 17: Rotate the handle to turn the ball valve to the closed state.

[0060] The process of inspecting or replacing the probe is completed.
