Description

Technical Field

[0001] This application relates to the technical field of precipitation well construction, and particularly to a modular and reusable continuous precipitation wellbore. Background Art

[0002] In the foundation of the construction site where there is confined water, pressure relief and emission reduction are required, the groundwater level is rising continuously, and there is no effective precipitation measure. Continuous precipitation of the foundation is carried out to keep the water level at the design elevation, ensure the construction quality of the foundation structure, and avoid being troubled by the rising groundwater.

[0003] When the existing wellbores for precipitation wells are under construction and connected, the two wellbores are directly connected, and then binding straps or bamboo strips are wound around and tied at the contact part of the two wellbores for limit fixation, so as to realize the splicing of the precipitation well wellbores. This splicing method is inconvenient for the docking operation during the construction of the wellbores. At the same time, the docking between the wellbores is not firm and is prone to separation, thus making the construction operation of the precipitation well wellbores inconvenient. Utility Model Content

[0004] In order to solve the problems of inconvenient docking operation and unreliable docking during the construction of the existing precipitation well wellbores, this application provides a modular and reusable continuous precipitation wellbore.

[0005] The modular and reusable continuous precipitation wellbore provided by this application adopts the following technical solutions:

[0006] A modular and reusable continuous precipitation wellbore includes a plurality of vertically stacked cylinders. The cylinders are connected end to end. A base is fixed at the lower end of the lowermost cylinder, and a water stop ring is fixedly sleeved on the outer side of the base. A cover plate is fixed at the upper end of the uppermost cylinder. A grouting pipe and a water extraction pipe are respectively fixed on the upper surface of the cover plate. A water extraction mechanism is inserted inside the water extraction pipe. A downwardly protruding first insertion edge is fixed at the lower end of the cylinder, and a plurality of uniformly arranged first buckle platforms are fixed on the outer circumferential surface of the first insertion edge. A first rubber ring is sleeved on the outer side of the first insertion edge. An annular second stop strip is fixed inside the upper port of the cylinder, and a plurality of uniformly arranged second relief openings are formed in the second stop strip.

[0007] By adopting the above technical solutions, when assembling the cylinders, the first insertion edge at the lower end of the upper cylinder is inserted inside the upper port of the lower cylinder. At this time, the first buckle platform passes through the second relief opening, and the upper cylinder is rotated so that the first buckle platform moves below the second stop strip, thus completing the docking and fixation between the two cylinders, making the assembly operation of the cylinders more convenient, and at the same time, the splicing between the cylinders is more stable and reliable.

[0008] Optionally, a plurality of reinforcing ribs are fixed on the outer side of the cylinder, and the reinforcing ribs are spirally fixed on the outer surface of the cylinder.

[0009] By adopting the above technical solution, the strength of the cylinder can be greatly enhanced through the reinforcing ribs, and by setting the reinforcing ribs in a spiral shape, a buffering effect can be achieved when the cylinder collides, reducing the situation of impact damage.

[0010] Optionally, a conical head is fixed at the lower end of the base, and handles are fixed near the upper ends on both the left and right sides of the base. An annular first stop strip is fixed inside the upper port of the base, and a plurality of first relief openings arranged in a circumferentially uniform manner are formed on the first stop strip.

[0011] By adopting the above technical solution, the base can be conveniently lifted through the handles, and the lifting rope can be tied and fixed through the handles, thus facilitating the use of the base when lowering it into the dewatering well.

[0012] Optionally, the water stop ring includes a ferrule sleeved on the outside of the base. A stop ring is fixed near the upper end on the outside of the ferrule, and a plurality of evenly arranged tightening screws are threadedly installed on the outside of the ferrule.

[0013] By adopting the above technical solution, the water stop ring is sleeved on the outside of the base through the ferrule, and the ferrule is locked and fixed through the tightening screws, thereby realizing the fixed installation of the water stop ring on the base.

[0014] Optionally, the pumping mechanism includes a submersible pump. A connecting pipe is connected to the upper end of the submersible pump, and a fixing seat is fixed on one side of the submersible pump. A water level monitoring mechanism for controlling the start and stop of the submersible pump is fixed on one side of the fixing seat.

[0015] By adopting the above technical solution, the water level in the dewatering well is monitored through the water level monitoring mechanism. When the water level in the dewatering well rises, the water level monitoring mechanism will be triggered, and the water level monitoring mechanism will start the submersible pump to pump water. When the water level drops to the set water level, the water level monitoring mechanism will control the submersible pump to stop working.

[0016] Optionally, the water level monitoring mechanism includes a float switch. The float switch is fixed on the fixing seat through a mounting plate, and a float ball is fixed to the upper end of the float switch through a connecting rod.

[0017] By adopting the above technical solution, when the water level is high, the float ball floats upward under the influence of buoyancy, thereby driving the float switch to open through the connecting rod. At this time, the submersible pump starts to pump and discharge the water in the dewatering well. And when the water level drops, the float ball drops, closing the float switch and causing the submersible pump to stop.

[0018] Optionally, a second insertion edge is fixed at the lower end of the cover plate, and a plurality of second fastening platforms arranged in a circumferentially uniform manner are fixed on the outside of the second insertion edge. A second rubber ring is sleeved on the outside of the second insertion edge, and two mounting threaded holes are formed on the upper surface of the cover plate.

[0019] By adopting the above technical solution, the cover plate is inserted into the inner side of the upper port of the lower cylinder body through the second insertion edge. At this time, the second buckle platform passes through the second relief opening, and the upper cylinder body is rotated so that the second buckle platform moves below the second stop bar, thus completing the docking and fixing between the cover plate and the cylinder body.

[0020] Optionally, a pressure ring is fixed on the outer side of the grouting pipe, and the grouting pipe is provided with an external thread at the lower side part of the pressure ring. A washer is sleeved on the grouting pipe at the external thread. The upper end of the grouting pipe is provided with a plug cover. A plurality of uniformly arranged lever rods are fixed on the outer circumferential surface of the plug cover, and a threaded head is fixed at the lower end of the plug cover.

[0021] By adopting the above technical solution, the grouting pipe is installed on the cover plate through the external thread, and the seal during installation is realized through the pressure ring and the washer. The upper port of the grouting pipe is blocked by installing the plug cover and the threaded head at the upper end of the grouting pipe to prevent construction waste from entering and polluting the groundwater.

[0022] In summary, the present application includes the following beneficial technical effects:

[0023] 1. When assembling the cylinder bodies, the first insertion edge at the lower end of the upper cylinder body is inserted into the inner side of the upper port of the lower cylinder body. At this time, the first buckle platform passes through the second relief opening, and the upper cylinder body is rotated so that the first buckle platform moves below the second stop bar, thus completing the docking and fixing between the two cylinder bodies, making the assembly operation of the cylinder bodies more convenient, and at the same time, the splicing between the cylinder bodies is more stable and reliable;

[0024] 2. The grouting pipe is installed on the cover plate through the external thread, and the seal during installation is realized through the pressure ring and the washer. The upper port of the grouting pipe is blocked by installing the plug cover and the threaded head at the upper end of the grouting pipe to prevent construction waste from entering and polluting the groundwater;

[0025] 3. When the water level is relatively high, the floating ball floats upward under the influence of buoyancy, thereby driving the float switch to open through the connecting rod. At this time, the submersible pump starts to pump and discharge the water in the dewatering well. When the water level drops, the floating ball descends, closing the float switch, causing the submersible pump to stop, avoiding equipment damage caused by the submersible pump running idly, and saving electric energy.

And a water extraction mechanism 6 is inserted inside the water extraction pipe 7. The water in the dewatering well is pumped outwards through the water extraction mechanism 6 for dewatering. A downwardly protruding first insertion edge 32 is fixed at the lower end of the cylinder 3. And a plurality of uniformly arranged first buckle platforms 31 are fixed on the outer circumferential surface of the first insertion edge 32. A first rubber ring 33 is sleeved on the outer side of the first insertion edge 32. An annular second stop strip 36 is fixed inside the upper port of the cylinder 3. And a plurality of uniformly arranged second relief openings 35 are formed in the second stop strip 36. When assembling the cylinder 3, the first insertion edge 32 at the lower end of the upper cylinder 3 is inserted inside the upper port of the lower cylinder 3. At this time, the first buckle platform 31 passes through the second relief opening 35, and the upper cylinder 3 is rotated so that the first buckle platform 31 moves below the second stop strip 36, thus completing the docking and fixing between the two cylinders 3, making the assembly operation of the cylinder 3 more convenient, and at the same time, the splicing between the cylinders 3 is more stable and reliable.

[0037] Refer to Figure 2 , a plurality of reinforcing ribs 34 are fixed on the outer side of the cylinder 3 and are uniformly arranged in a circular shape. And the reinforcing ribs 34 are fixed on the outer surface of the cylinder 3 in a spiral shape. The cylinder 3 can greatly enhance the strength of the cylinder 3 through the reinforcing ribs 34, and by setting the reinforcing ribs 34 in a spiral shape, a buffering effect can be achieved when the cylinder 3 collides, reducing the situation of impact damage.

[0038] Refer to Figure 3 , a cone head 11 is fixed at the lower end of the base 1. And handles 12 are fixed at the upper ends of the left and right sides of the base 1. The base 1 is convenient to be lifted through the handles 12, and the lifting ropes can be tied and fixed through the handles 12, thus facilitating the use when the base 1 is lowered into the dewatering well. An annular first stop strip 14 is fixed inside the upper port of the base 1. And a plurality of first relief openings 13 are formed in the first stop strip 14 and are uniformly arranged in a circular shape.

The water level in the precipitation well is monitored by the water level monitoring mechanism 62. When the water level in the precipitation well rises, the water level monitoring mechanism 62 will be triggered, and the water level monitoring mechanism 62 will start the submersible pump 63 to pump water. When the water level drops to the set water level, the water level monitoring mechanism 62 will control the submersible pump 63 to stop working.

When the water level is high, the float ball 621 floats upward due to the buoyancy, thereby driving the float switch 623 to open via the connecting rod 622. At this time, the submersible pump 63 starts to pump out the water in the precipitation well, and when the water level drops, the float ball 621 drops to close the float switch 623, thereby stopping the submersible pump 63.

[0042] Reference Figure 7 A second insert edge 43 is fixed to the lower end of the cover plate 4, and a plurality of second buckle platforms 44 arranged uniformly in a circumferential shape are fixed to the outer side of the second insert edge 43. The cover plate 4 is inserted into the inner side of the upper port of the lower cylinder 3 through the second insert edge 43. At this time, the second buckle platform 44 passes through the second yielding port 35, and the upper cylinder 3 is rotated so that the second buckle platform 44 moves to the bottom of the second baffle 36, thereby completing the docking and fixation between the cover plate 4 and the cylinder 3. A second rubber ring 42 is sleeved on the outer side of the second insert edge 43. Two mounting threaded holes 41 are provided on the upper surface of the cover plate 4 for installing the grouting pipe 5 and the pumping pipe 7.

The plug cover 51 is conveniently screwed by the lever 52, thereby facilitating the installation or removal of the plug cover 51.

[0044] The implementation principle of a modular, rotatable, and continuous precipitation wellbore of the embodiment of the present application is as follows: when constructing the cylinder 3 of the precipitation well, a rope is fastened to the handle 12 of the base 1, and then the rope is tightened from both sides to slowly sink the base 1 into the precipitation well. At this time, the first insertion edge 32 at the lower end of the cylinder 3 is inserted into the inner side of the upper port of the lower base 1. At this time, the first buckle platform 31 passes through the first yielding opening 13, and the upper cylinder 3 is rotated so that the first buckle platform 31 moves to the bottom of the first stop bar 14 to complete the docking and fixation of the cylinder 3 on the base 1, and then the first insertion edge 32 at the lower end of the upper cylinder 3 is inserted into the inner side of the upper port of the lower cylinder 3. At this time, the first buckle platform 31 passes through the second yielding opening Position opening 35, and rotate the upper cylinder 3 so that the first buckle platform 31 moves to the bottom of the second baffle 36 to complete the docking and fixation between the two cylinders 3. While assembling the cylinder 3, the rope is lowered to make the cylinder 3 sink. Finally, the cover plate 4 is installed on the uppermost cylinder 3, and the submersible pump 63 and the water level monitoring mechanism 62 are placed in the precipitation well. When the water level is high, the float 621 floats upward due to the buoyancy, thereby driving the float switch 623 to open through the connecting rod 622. At this time, the submersible pump 63 starts to pump out the water in the precipitation well, and when the water level drops, the float 621 drops to close the float switch 623, thereby stopping the submersible pump 63.
