Description

Technical Field

[0001] This invention relates to a prefabricated remote hole cleaning water level monitoring device, belonging to the field of foundation pit monitoring and support technology. Background Technology

[0002] In foundation pit support design, the installation of water level monitoring holes is a standard practice. Many foundation pit collapse accidents are caused by soil erosion and changes in groundwater levels.

[0003] The conventional method for setting up and monitoring water levels involves manually drilling holes and periodically conducting observations. However, many water level monitoring holes suffer from siltation due to the presence of sediment in the groundwater. Over time, this sediment enters the monitoring holes through the permeable pores, inevitably causing siltation and blockage at the bottom. This also clogs the permeable pores, leading to inaccurate data and even rendering the monitoring holes unusable. Re-drilling the holes is time-consuming and labor-intensive, and manual water level monitoring is also time-consuming and labor-intensive. Summary of the Invention

[0015] Beneficial effects

[0016] 1. The equipment of this invention mainly consists of prefabricated, assembled components. It is highly versatile and easy and quick to assemble. Each individual component is small in size, enabling rapid assembly.

[0017] 2. This invention can periodically and automatically or remotely clean the water level observation wells, remove the mud accumulated at the bottom of the borehole, improve the observation accuracy, and extend the life of the observation wells.

[0018] 3. This invention can periodically and automatically or remotely measure the water level in the water level observation hole, and the measurement is non-manual. The measured data can be remotely transmitted to the remote control system.

[0019] 4. The porous cotton filling the double-walled prefabricated pipe at the bottom of the invention plays a role in initially filtering impurities in the groundwater, thus delaying siltation and extending the life of the observation well.

[0020] 5. The drill rod of this invention has a hollow design, and the hollow cavity is a water injection chamber. While water is being injected, the drill rod rotates, and the blades form a spiral upward water flow, which dilutes the mud and drives the mud sediment to be backflushed from the bottom to the pipe opening. At the same time, the drill rod injects water into the bottom of the borehole, which generates reverse water pressure on the porous cotton between the double pipe walls, achieving a reverse flushing effect, washing away impurities and silt inside the porous cotton, and increasing the water permeability and filtration effect of the porous cotton.

[0021] 6. The mud-water filtration sedimentation tank of the present invention is a double-cavity interlayer with sponge filtration and a drop between the cavities. The sponge design in the cavities is to filter and replace the water so that it can be recycled. The sponge is a filter element that can be replaced or rinsed and reused. The drop between the cavities is intended to accelerate the flow of water by gravity.

[0022] 7. The dust cover of the present invention has an arc-shaped top surface, which effectively prevents rainwater and debris from falling into the pipe opening after the observation hole has been placed for a long time, causing inaccurate water level observation or rendering the observation hole unusable.

[0023] 8. The probe of this invention is spherical, which can roll down in contact with the inner wall of the pipe to ensure the accuracy of the measurement.

[0024] 9. All components of this invention can be reused multiple times, are inexpensive, use energy-saving and environmentally friendly materials, and do not pollute the soil.

[0038] Further, the drill rod 2 includes a hollow rod 21 and blades 22 connected to the outside of the hollow rod 21. The hollow rod 21 is connected to the mud-water filtration sedimentation tank 9 through the water injection pipe 10. Multiple drill rods 2 are interconnected and located within multiple interconnected prefabricated pipe fittings 1. The top of each interconnected drill rod 2 is provided with a water inlet 23 and an adapter 24. The water inlet 23 is connected to the water injection pipe 10, and the adapter 24 is located below the water inlet 23. A rotary motor 23 is rotatably connected to each drill rod 2, and the rotary motor 23 drives the drill rod 2 to rotate. The adapter 24 separates the hollow rod 21 located above and below the adapter 24, allowing the drill rod 2 below the adapter 24 to rotate with the rotary motor 23, while fixing the drill rod 2 above the adapter 24, thus facilitating the connection between the water inlet 23 and the water injection pipe 10.

[0039] Optionally, the blade 22 is twisted; the drill rod 2 is made of nylon, and the hollow rod 21 has a hollow structure with an inner diameter of 3cm and an outer diameter of 4cm. The length of a single drill rod 2 is 50cm, and adjacent hollow rods 21 are connected by threads, with a threaded opening at the top and a threaded female opening at the bottom.

[0040] Furthermore, the prefabricated pipe fitting 1 located at the bottom of a plurality of interconnected prefabricated pipe fittings 1 has a double-layered pipe wall and a bottom cover 11. The double-layered pipe wall has permeable holes, and porous cotton 12 is disposed between the double-layered pipe wall. An internal support 15 is provided inside the prefabricated pipe fitting 1 to ensure that the drill rod 2 will not impact the pipe wall of the prefabricated pipe fitting 1 due to swinging during rotation. A circular hole with a diameter of 5cm is provided in the center of the internal support 15 to facilitate the insertion of the drill rod 2. Adjacent prefabricated pipe fittings 1 are connected by a first snap-fit ​​13, and a rubber ring 14 is provided between adjacent prefabricated pipe fittings 1 to prevent leakage. Optionally, the prefabricated pipe fitting 1 is made of nylon, and the length of a single prefabricated pipe fitting 1 is 50cm.

[0041] Furthermore, a protective cover 4 is provided above multiple interconnected prefabricated pipe fittings 1. The protective cover 4 is made of plastic, is 1 meter high, and has a counterweight plate as its base, which is fixed to the ground. The protective cover 4 is arc-shaped to prevent rainwater and debris from falling into the pipe of the prefabricated pipe fitting 1.

[0042] Furthermore, the mud-water filtration and sedimentation tank 9 includes a filtration chamber 92 and a water storage chamber 93. A sponge block 91 is disposed between the filtration chamber 92 and the water storage chamber 93. The mud-water in the filtration chamber 92 flows into the water storage chamber 93 after being filtered by the sponge block 91. Optionally, the thickness of the sponge block 91 is 10cm, and the sponge block 91 can be removed, rinsed, reused, or replaced. A water pump 5 is disposed in the water storage chamber 93. The water pump 5 is connected to the water injection pipe 10. The water pump 5 is used to send the clean water in the water storage chamber 93 into the interior of the hollow rod 21 of the drill rod 2 through the water injection pipe 10.

[0043] Furthermore, the measuring mechanism 6 also includes a second buckle 61, the winch 63 is connected to the precast pipe 1 through the second buckle 61, the cable 64 is provided with signal lines and cables, and the cable 64 is connected to the solar power mechanism 7 and the signal transmitting and receiving mechanism 8.

[0044] Furthermore, the signal transmitting and receiving mechanism 8 is also connected to the rotary motor 3, the probe 62, the winch 63, and the water pump 5. The signal transmitting and receiving mechanism 8 controls the start and stop of the rotary motor 3, the water pump 5, and the winch 63 and receives measurement data.

[0045] Furthermore, the solar power mechanism 7 is connected to the rotary motor 3, water pump 5, winch 63, probe 62, and signal transmitting and receiving mechanism 8. The solar power mechanism 7 collects solar energy and converts it into electrical energy to power the aforementioned components.

[0046] The working principle of this invention is as follows: A drill bit with the same outer diameter as the prefabricated pipe fitting 1 is used to drill a hole to a predetermined design depth, which is the depth of the underground aquifer. Geological surveys are required to determine the depth of the aquifer beforehand. The bottom cover 11 of the prefabricated pipe fitting 1 is unscrewed, and simultaneously, a drill rod 2 is inserted into the prefabricated pipe fitting 1 from the bottom. The bottom cover 11 is then screwed back on and placed into the borehole. A sufficient number of prefabricated pipe fittings 1 and drill rods 2 are connected according to the sequence and depth of the borehole. The sequence is as follows: unscrew the bottom cover 11 of the prefabricated pipe fitting 1, insert the drill rod 2 from the bottom upwards, screw the bottom cover 11 back on, then connect another drill rod 2 to the upper part of the drill rod 2, and then fit another prefabricated pipe fitting 1 on top. This process is repeated. The measuring mechanism 6 is hung on the wall of the prefabricated pipe fitting 1 at the exposed end, and the probe 62 is attached vertically to the inside of the pipe wall. The water pump 5 is placed in the mud-water filtration sedimentation tank 9, and the tank is initially filled with water.

[0047] Once all equipment is installed and connected, when long-term observation of the water level is required, the remote control room sends a signal to the rotary motor 3 and water pump 5 via the signal transmitting and receiving mechanism 8. The rotary motor 3 starts, driving the drill rod 2 to rotate. Simultaneously, the water pump 5 injects clean water from the top of the hollow rod 21 of the drill rod 2 to the bottom. The sediment and clean water inside the pipe mix and rotate, forming an upward water flow that washes the perforated pipe wall and simultaneously backwashes the porous cotton 12 filling the space between the two layers of pipe walls. The diluted mud water displaced flows from the pipe outlet above ground into the filtration chamber 92 of the mud-water filtration sedimentation tank 9. After preliminary filtration by the sponge block 91, it flows into the chamber of the water pump 5 for recycling.

[0048] After rinsing for a period of time, the time is generally set according to the number of prefabricated pipe fittings 1 inserted, which can be set to 3 minutes per prefabricated pipe fitting 1. After standing for a period of time, generally 30 minutes, until the water level stabilizes, the remote control room sends a signal to the measuring mechanism 6 through the signal transmitting and receiving mechanism 8. The winch 63 then operates, and the cable 64 wound on the winch 63, along with the probe 62, is inserted into the inner wall of the prefabricated pipe fitting 1 at a uniform speed. When the probe 62 encounters water, it sends a signal to the signal transmitting and receiving mechanism 8, which then sends a feedback signal back to the control room. The distance from the pipe opening to the water surface inside the pipe is obtained by multiplying the time difference between the start time of the winch 62 and the time when the probe 62 encounters water and sends a signal by the speed at which the winch 62 operates (this is the initially preset speed, which can be 2 cm / s), thus obtaining the height of the water level inside the pipe.

[0049] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
