Description

Technical Field

[0001] The present invention relates to the technical field of mud extraction, in particular to a mud extraction device for construction engineering. Background Art

[0002] In the field of engineering construction, buildings need a solid foundation, and the construction of the foundation requires drilling holes in the foundation pit, and then driving pipe piles into the holes for subsequent construction.

[0003] If the pipe piles are not driven in time after drilling, rainwater will flow into the borehole along with silt in windy and rainy weather, causing the borehole to be filled with mud, and the entire borehole to be filled with muddy water, affecting the driving of the pipe piles. The borehole is located in the building foundation pit, and when it rains, it will also cause water accumulation in the lower areas of the foundation pit. When the water in the foundation pit and the borehole overlap, it will cause a safety hazard. Workers cannot distinguish whether it is water in the foundation pit or water in the borehole, making it difficult to carry out construction work.

[0004] To solve the above problems, the existing technology adopts a method of simultaneously pumping water and manually cleaning silt. However, after the accumulated water in the borehole is pumped out, the depth of the borehole is relatively deep, and the internal mud is deposited at the bottom of the borehole. It is inconvenient for workers to use tools to remove the bottom mud. At this time, a device is needed to conveniently clean the mixed mud water in the borehole. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a mud extraction device for construction engineering.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a mud extraction device for construction engineering construction, comprising an outer sleeve and an adjusting structure, the inner wall of the outer sleeve is slidably connected to the inner sleeve, the size of the inner sleeve is smaller than the size of the outer sleeve, the upper ends of the outer sleeve and the inner sleeve are provided with an adjusting structure for extracting mud, the adjusting structure comprises an outer convex block and an inner convex block, one side of the outer convex block and the inner convex block are fixedly connected to the outer sleeve and the inner sleeve respectively, the upper surface of the outer convex block is fixedly connected to a movable shaft, the arc surface of the movable shaft is slidably connected to the inner convex block, the arc surface of the movable shaft is sleeved with a spring, and the two ends of the spring are respectively connected to the outer The convex block and the inner convex block abut against each other, and a fishing assembly for salvaging mud is provided inside the inner sleeve, and the fishing assembly includes a fixing rod, which is passed through the interior of the inner sleeve, and the length of the fixing rod is adapted to the internal depth of the inner sleeve. The lower end of the fixing rod is fixedly connected to a connecting plate, and the cross-section of the connecting plate is an inverted "T" shape. Two limit blocks are fixedly connected on both sides of the connecting plate, and a semi-rotating disk is rotatably connected between the two limit blocks. A plurality of external water inlet holes are evenly opened on the arc surface of the outer sleeve, and a plurality of internal water inlet holes are opened on the inner sleeve relative to the position of the external water inlet holes, and the size of the internal water inlet holes is larger than that of the external water inlet holes.

[0007] When the auger is pushed down, the spring is released, and the auger is pushed outwards, so that the auger is pushed back into the well. When sliding downward, the inner water inlet hole opened on its surface will drop to a position overlapping with the outer water inlet hole. When the two overlap, an opening will appear. At this time, the mud mixed water outside the outer sleeve will flow into the inner sleeve through the outer water inlet hole and the inner water inlet hole. In the process of continuous influx of mud and water into the inner sleeve, the weight of the inner sleeve will continue to increase, and the spring will continue to be compressed, causing the inner sleeve to continue to drop until the inner water inlet hole completely passes through the outer water inlet hole and the two no longer overlap. At this time, the mud water cannot enter the interior of the inner sleeve, and then the fixed stick can be pulled upward so that the connecting plate at its lower end and the two semi-rotating disks can completely extract the mud water in the inner sleeve upward, and then repeat this process until the mud mixed water in the mud borehole is completely extracted, thereby making the extraction process of the mud mixture more stable and more efficient.

[0008] Preferably, the arc surface of the semi-rotating disk is fixedly connected with an arc-shaped baffle, and the size of the arc-shaped baffle is adapted to the size of the semi-rotating disk.

[0009] By adopting this preferred solution, the arc-shaped baffle lifts the four sides of the semi-rotating disk to a certain height, so that the solid mud settled at the bottom of the mud mixed water can be stuck on the surface of the semi-rotating disk. When extracting mud water, the mud can be effectively lifted out of the borehole, avoiding the problem of difficulty in extracting mud from the borehole.

[0010] Preferably, a plurality of latching teeth are evenly and fixedly connected to the surface of the semi-rotating disk, and one side of the latching teeth is fixedly connected to the arc-shaped baffle.

[0011] By adopting this preferred solution, the latching teeth increase the friction force on the surface of the semi-rotating disk, and cooperate with the arc-shaped baffle to better retain the solid mud at the bottom of the muddy water.

[0012] Preferably, an annular gasket is fixedly connected to the arc surface of the arc baffle, and the size of the annular gasket is adapted to the size of the arc baffle.

[0013] With this preferred solution, the annular pad is used on the outer arc surface of the arc baffle to rub against the inner wall of the inner sleeve, while reducing the amount of muddy water leaking downward from the outer surface of the arc baffle, making the extraction of muddy water more stable.

[0014] Preferably, two sealing pads are fixedly connected to both sides of the connecting plate, the upper surface of the sealing pad is in an arc-shaped concave shape, and the sealing pad is a rubber pad.

[0015] By adopting this preferred solution, the sealing gasket can be used to seal the connection between the semi-rotating disk and the limit block, thereby reducing the amount of muddy water leaking downward during extraction.

[0016] Preferably, the upper surface of the connecting plate is provided with an auxiliary structure for facilitating pulling out, and the auxiliary structure includes two auxiliary pull ropes, the lower ends of the auxiliary pull ropes are fixedly connected to the connecting plate, and the two auxiliary pull ropes are symmetrically distributed along the center line of the fixed stick, and the arc surface of the fixed stick is fixedly connected to two positioning plates near the upper end, and four rotating shafts are rotatably connected between the two positioning plates. The four rotating shafts are in groups of two and distributed on both sides of the fixed stick, and the arc surface of the rotating shaft is fixedly connected to a positioning wheel, and the auxiliary pull rope passes between the two positioning wheels.

[0017] By adopting the above technical solution, when it is necessary to lift the fixed rod upward, it is only necessary to pull the auxiliary pull rope passed between the positioning wheels. The two pull ropes can be bent to the same direction and pulled upward, driving the connecting plate and the semi-rotating disk below to move upward, thereby avoiding the problem that the fixed rod in a fixed state cannot adjust the upward stretching direction, thereby requiring the worker to jump out and pull it upward.

[0018] Preferably, the fixing stick is fixedly connected to a thick shaft near the upper surface of the positioning plate, the size of the thick shaft is larger than the size of the fixing stick, the arc surface of the fixing stick is rotatably connected to a focusing disk near the lower end of the thick shaft, the arc surface of the focusing disk is provided with a groove, and the upper surface of the focusing disk is rotatably connected to a handle.

[0019] With this preferred solution, when the auxiliary pull rope is not needed, it can be wound around the inner wall of the tightening disk, and the handle can be turned to drive the auxiliary pull rope to be continuously wound in, thereby fixing the auxiliary pull rope.

[0020] Preferably, the arc surface of the fixed rod is fixedly connected to two limiting rings, and the two auxiliary pull ropes both pass through the inner walls of the limiting rings.

[0021] By adopting this preferred solution, the auxiliary pull rope is limited by two limiting rings, so that the auxiliary pull rope is close to the fixed stick, avoiding the auxiliary pull rope bundle from being messy and affecting mud extraction.

[0022] Preferably, a support structure for reinforcing the fixing strength of the outer sleeve is provided near the upper end of the arc surface of the outer sleeve, and the support structure includes two support plates, one side of the support plate is fixedly connected to the outer sleeve, and the upper surface of the outer sleeve is fixedly connected to two fixed blocks near the support plate, and the inner part of the support plate is slidably connected to a slider, and the upper surface of the support plate is provided with a sliding groove, and the upper surface of the slider is fixedly connected to a rectangular plate near the sliding groove, and the two sides of the rectangular plate are fixedly connected to cross plates, and the internal thread of the rectangular plate is connected to a screw, one end of the screw is rotatably connected to the fixed block, and the other end of the screw is fixedly connected to the handrail, and the inner part of the slider is slidably connected to a steel nail.

[0023] By adopting the above technical solution, when the outer sleeve is placed into the drill hole, the two support plates on its arc surface are used to support on both sides of the drill hole to fix the outer sleeve. Then the armrest can be rotated to drive the screw to rotate and adjust the front and rear position of the rectangular plate on the arc surface of the screw, driving the slider under the rectangular plate to extend outward in the support plate. The slider is extended to a certain length to avoid the soft soil close to the drill hole, which makes it inconvenient to fix. Then, steel nails are driven into the slider and the steel nails are driven into the hard soil, thereby fixing the outer sleeve and making the mud extraction of the outer sleeve more stable.

[0024] Preferably, the slider and the lower surface of the support plate are both fixedly connected with two spikes, and the sizes of the two spikes are adapted to each other.

[0025] With this preferred solution, the spikes can penetrate the ground at the same time, thereby making the fixation of the slider and the support plate more stable, thereby enhancing the stability of mud extraction.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are:

[0027] 1. In the present invention, by setting an adjustment structure, when it is necessary to extract mud, the outer sleeve is first inserted inwardly into the mud drill hole to be extracted, and the inner sleeve is inserted into the drill hole together with the outer sleeve. At this time, the spring is in a completely relaxed state, and the inner convex block and the inner sleeve are lifted up by one end distance, so that the inner sleeve extends outward by one end distance of the outer sleeve. At this time, the outer water inlet hole and the inner water inlet hole are staggered, and the inner water inlet hole is located at the upper end of the outer water inlet hole. After the outer sleeve is inserted downward, since the outer water inlet hole and the inner water inlet hole are staggered, the mud mixed water in the drill hole cannot enter the inner water inlet hole. The inside of the sleeve, then insert the fixed stick with the connecting plate and the semi-rotating disk into the inner sleeve, so that the arc surface of the semi-rotating disk slides downward on the inner wall of the inner sleeve, and slides until the connecting plate abuts against the bottom end of the inner sleeve. At this time, continue to press the fixed stick downward so that the bottom end of the connecting plate below drives the inner sleeve to move downward. The downward movement of the inner sleeve drives the inner convex block to compress the spring on the arc surface of the movable shaft downward, so that the spring is compressed. At the same time, the inner convex block slides downward on the arc surface of the movable shaft. The inner sleeve continues to slide downward, and drives a number of inner water inlet holes opened on its arc surface. When the inner water inlet hole moves downward to a position where it coincides with the outer water inlet hole, the two coincide and an opening is opened. At this time, the mud mixed water outside the outer sleeve will flow in from the opening, and the mud mixed water passes through the outer water inlet hole and the inner water inlet hole in turn, and then reaches the inside of the inner sleeve. The mud water continues to flow in, making the overall weight of the inner sleeve continue to increase. At this time, the pressing and fixing stick can be released. After the mud water completely flows into the inner sleeve, the inner sleeve continues to sink due to the weight and compresses the spring. In this process, the position of the inner water inlet hole continues to move upward. The inner sleeve moves downward until it completely passes through the outer water inlet hole, and the two are staggered again. At this time, the inner water inlet hole is located at the lower end of the outer water inlet hole, so that the opening is closed. Subsequently, the mud water cannot flow into the inner sleeve. At this time, the fixed stick can be pulled upward to drive the connecting plate and the semi-rotating disk at the lower end to lift the mud mixed water upward and completely extract the mud inside the inner sleeve. The inner sleeve with reduced weight will continue to rise to the initial position under the action of the spring rebound force, waiting for the next cycle. After multiple cycles, the mud water and solid mud in the borehole can be completely extracted.

[0028] 2. In the present invention, when the fixed stick drives the lower semi-rotating disk to slide towards the bottom of the inner sleeve, if there is mud mixed water inside the inner sleeve, continuing to press the fixed stick downward will encounter water resistance. Because the force is mutual, when the fixed stick is pressed downward, the water will also give an upward force, which will push the rotatable semi-rotating disk to rotate upward. The semi-rotating disk rotates upward between the limit blocks, creating space for the mud mixed water below to flow out and surge upward, thereby reducing the force pressing down on the fixed stick, making the pressing more labor-saving and convenient. When the connecting plate reaches the bottom of the inner sleeve, the semi-rotating disk will rotate downward due to gravity and return to its initial position. When the fixed stick is subsequently lifted, the semi-rotating disk will not rotate downward due to the inverted "T"-shaped obstruction at the lower end of the connecting plate, thereby ensuring the efficient and stable mud extraction.

[0029] 3. In the present invention, an auxiliary structure is provided. When the fixed stick needs to be lifted upward, the fixed stick is in a fixed state and is located in the center of the inner sleeve. The worker needs to jump out of the body, but cannot fully exert force by jumping out of the body. At this time, the two auxiliary pull ropes at the upper end of the fixed stick can be pulled, and the auxiliary pull ropes can be bent to the same position. By pulling the auxiliary pull ropes, full force can be exerted, and the connecting plate at the lower end of the auxiliary pull rope and the two semi-rotating disks can be driven upward, and the two auxiliary pull ropes are limited by the positioning wheels. When the auxiliary pull ropes are bent, the positioning wheels can support them to prevent the auxiliary pull ropes from being rubbed against the edge of the drill hole due to lack of limit. When the auxiliary pull ropes are not needed, the two auxiliary pull ropes only need to be wound around the inner wall of the cluster disk, and then the handle can be turned to quickly wind the auxiliary pull ropes around the cluster disk for fixation, avoiding their disorderly placement.

[0030] 4. In the present invention, by setting a supporting structure, after the outer sleeve is placed in the drilled hole, the two support plates on its arc surface can be supported on the outside of the drilled hole, thereby supporting the outer sleeve and facilitating subsequent work. Subsequently, the armrest is rotated to rotate the screw, and the screw rotates on one side of the fixed block and drives the rectangular plate on its arc surface to move, so that the rectangular plate drives the slider at its lower end to slide out from the support plate. The cross plate is used to limit the upper end of the rectangular plate, so that the rectangular plate cannot move up and down when used in conjunction with the slider, making its work more stable. After the slider slides out, the supporting distance of the support plate is extended, and the soil away from the drilled hole is harder, so the supporting effect is better. Subsequently, the slider and the spikes at the lower end of the support plate can be inserted into the ground for fixation, and steel nails can be driven into the ground from the inside of the slider to strengthen the fixing effect and make the extraction process of mud mixed water more stable.

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0044] Example 1, as Figure 1-10 As shown, the present invention provides a mud extraction device for construction engineering, including an outer sleeve 1 and an adjustment structure 3. The inner wall of the outer sleeve 1 is slidably connected to the inner sleeve 2. The size of the inner sleeve 2 is smaller than that of the outer sleeve 1. The upper ends of the outer sleeve 1 and the inner sleeve 2 are provided with an adjustment structure 3 for extracting mud, and the upper surface of the connecting plate 352 is provided with an auxiliary structure 4 for facilitating pulling out. The arc surface of the outer sleeve 1 is provided near the upper end with a support structure 5 for reinforcing the fixing strength of the outer sleeve 1.

[0045] The following describes in detail the specific settings and functions of the adjustment structure 3, the auxiliary structure 4 and the support structure 5.

[0046] like Figure 2 - Figure 7As shown, the adjustment structure 3 includes an outer convex block 31 and an inner convex block 32. One side of the outer convex block 31 and the inner convex block 32 are fixedly connected to the outer sleeve 1 and the inner sleeve 2 respectively. The upper surface of the outer convex block 31 is fixedly connected to a movable shaft 33. The arc surface of the movable shaft 33 is slidably connected to the inner convex block 32. The arc surface of the movable shaft 33 is sleeved with a spring 34. The two ends of the spring 34 are respectively in contact with the outer convex block 31 and the inner convex block 32. The interior of the inner sleeve 2 is provided with a fishing assembly 35 for fishing mud. The fishing assembly 35 includes a fixed rod 351. The fixed rod 351 is inserted into the inner sleeve 2. Inside the sleeve 2, the length of the fixed rod 351 is adapted to the internal depth of the inner sleeve 2. The lower end of the fixed rod 351 is fixedly connected to a connecting plate 352. The cross-section of the connecting plate 352 is an inverted "T" shape. Two limit blocks 353 are fixedly connected on both sides of the connecting plate 352. A semi-rotating disk 354 is rotatably connected between the two limit blocks 353. A plurality of external water inlet holes 36 are evenly opened on the arc surface of the outer sleeve 1, and a plurality of internal water inlet holes 37 are opened on the position relative to the external water inlet holes 36. The size of the internal water inlet holes 37 is larger than that of the external water inlet holes 36. When mud is extracted, the outer sleeve 1 sleeved on the outside of the inner sleeve 2 is placed in the mud drill hole to be extracted. At this time, the spring 34 is in a completely relaxed state, and the inner sleeve 2 is extended outward by one end of the inner sleeve 1. At the same time, the inner water inlet hole 37 on the arc surface of the inner sleeve 2 is higher than the outer water inlet hole 36 on the arc surface of the outer sleeve 1. The inner water inlet hole 37 and the outer water inlet hole 36 are in a staggered state, so that the mud mixed water outside the outer sleeve 1 will not enter the inner sleeve 2. Then the fixing rod 351 can be inserted into the inner sleeve 2, driving the connecting plate 352 at its lower end and the two semi-rotating disks 354 to slide downward along the inner wall of the inner sleeve 2. Then the connecting plate 352 abuts against the bottom end of the inner sleeve 2. At this time, the fixing rod 351 is continuously pressed down, so that the connecting plate 352 presses the inner sleeve 2 downward, and the inner convex block 32 at the upper end of the inner sleeve 2 compresses the spring 34 downward, so that the inner sleeve 2 slides downward inside the outer sleeve 1. When the inner sleeve 2 slides downward, the inner water inlet hole 37 opened on its surface will drop to a position overlapping with the outer water inlet hole 36. When the two overlap, an opening will appear, and the mud mixed water outside the outer sleeve 1 will flow into the inner sleeve 2 through the outer water inlet hole 36 and the inner water inlet hole 37. In the process of continuous influx of mud and water into the inner sleeve 2, the weight of the inner sleeve 2 will continue to increase, and the spring 34 will continue to compress, causing the inner sleeve 2 to continue to drop continuously until the inner water inlet hole 37 completely passes through the outer water inlet hole 36 and the two no longer overlap. At this time, the mud water cannot enter the interior of the inner sleeve 2, and then the fixed rod 351 can be pulled upward so that the connecting plate 352 at its lower end and the two semi-rotating disks 354 can completely extract the mud water in the inner sleeve 2 upward, and then repeat this process until the mud mixed water in the mud borehole is completely extracted, thereby making the extraction process of the mud mixture more stable and more efficient.

[0047] Furthermore, a curved baffle 355 is fixedly connected to the circular surface of the semi-rotating disk 354. The curved baffle 355 is sized to match the size of the semi-rotating disk 354. The curved baffle 355 elevates the perimeter of the semi-rotating disk 354 to a certain height, allowing solid mud that settles at the bottom of the mud mixture to be captured on the surface of the semi-rotating disk 354. This effectively pulls the mud out of the borehole during mud water extraction, avoiding the problem of difficulty in extracting the mud from the borehole. Several latches 356 are evenly fixedly connected to the surface of the semi-rotating disk 354, one side of which is fixedly connected to the curved baffle 355. The latches 356 increase the friction on the surface of the semi-rotating disk 354 and, in conjunction with the curved baffle 355, better retain the solid mud at the bottom of the mud mixture. An annular pad 357 is fixedly connected to the circular surface of the curved baffle 355, and its size matches that of the curved baffle 355. Annular gaskets 357 are used on the outer arc surface of the arc-shaped baffle 355 to rub against the inner wall of the inner sleeve 2, thereby reducing the amount of muddy water leaking downward from the outer surface of the arc-shaped baffle 355, ensuring more stable muddy water extraction. Two sealing gaskets 358 are fixedly connected to either side of the connecting plate 352. The upper surfaces of these sealing gaskets 358 are curved, concave rubber pads. These seals at the junction of the semi-rotating disc 354 and the stop block 353, reducing the amount of muddy water leaking downward during extraction.

[0048] The effect achieved by the entire adjustment structure 3 is that the fixed rod 351 with the connecting plate 352 and the semi-rotating disk 354 is inserted into the inner sleeve 2, so that the arc surface of the semi-rotating disk 354 slides downward on the inner wall of the inner sleeve 2 until the connecting plate 352 abuts against the bottom end of the inner sleeve 2. At this time, the fixed rod 351 is continued to be pressed downward, so that the bottom end of the lower connecting plate 352 drives the inner sleeve 2 to move downward, and the downward movement of the inner sleeve 2 drives the inner protrusion 32 to be compressed downward in the circular shape of the movable shaft 33. The spring 34 on the arc surface compresses the spring 34, and at the same time, the inner convex block 32 slides downward on the arc surface of the movable shaft 33, and the inner sleeve 2 continues to slide downward, and drives the several inner water inlet holes 37 opened on its arc surface to move downward. When the inner water inlet hole 37 moves downward to a position where it coincides with the outer water inlet hole 36, the two coincide and an opening is opened. At this time, the mud mixed water outside the outer sleeve 1 will flow in from the opening, and the mud mixed water will pass through the outer water inlet hole 36 and the inner water inlet hole 37 in turn, and then When the slurry reaches the inside of the inner sleeve 2, the muddy water continues to flow in, causing the overall weight of the inner sleeve 2 to continue to increase. At this time, the pressing fixed rod 351 can be released. After the muddy water completely flows into the inner sleeve 2, the inner sleeve 2 continues to sink due to its weight and compresses the spring 34. In this process, the position of the inner water inlet hole 37 continues to move downward until it completely passes through the outer water inlet hole 36. The two are staggered again. At this time, the inner water inlet hole 37 is located at the lower end of the outer water inlet hole 36, which closes the opening. Subsequently, the muddy water cannot flow into the inner sleeve 2. At this time, the fixing rod 351 can be pulled upward, driving the connecting plate 352 and the semi-rotating disk 354 at the lower end to lift the mud mixed water upward and completely extract the mud inside the inner sleeve 2. The inner sleeve 2 with reduced weight will continue to rise to its initial position under the action of the rebound force of the spring 34, waiting for the next cycle. Through multiple cycles, the muddy water and solid mud in the borehole can be completely extracted, making the extraction of mud mixed water more efficient and stable.

[0049] like Figure 8 and Figure 9As shown, the auxiliary structure 4 includes two auxiliary pull ropes 401, the lower ends of which are fixedly connected to the connecting plate 352. The two auxiliary pull ropes 401 are symmetrically distributed along the midline of the fixed rod 351. Two positioning plates 402 are fixedly connected to the arc surface of the fixed rod 351 near the upper end. Four rotating shafts 403 are rotatably connected between the two positioning plates 402. The four rotating shafts 403 are grouped in two and distributed on both sides of the fixed rod 351. The arc surfaces of the rotating shafts 403 are fixedly connected to positioning wheels 404, and the auxiliary pull ropes 401 pass between the two positioning wheels 404. When it is necessary to lift the fixed rod 351 upward, it is only necessary to pull the auxiliary pull rope 401 passing between the positioning wheels 404, which can bend the two pull ropes to the same direction and pull them upward, driving the lower connecting plate 352 and the semi-rotating disk 354 to move upward. This avoids the problem that the fixed rod 351 in a fixed state cannot adjust the upward stretching direction, thereby requiring the worker to move up to pull it upward.

[0050] Among them, the fixed rod 351 is fixedly connected to a thick shaft 405 at a position near the upper surface of the positioning plate 402. The size of the thick shaft 405 is larger than that of the fixed rod 351. The arc surface of the fixed rod 351 is rotatably connected to a gathering disk 407 near the lower end of the thick shaft 405. The arc surface of the gathering disk 407 is provided with a groove, and the upper surface of the gathering disk 407 is rotatably connected to a handle 408. When the auxiliary pull rope 401 is not needed, it can be wound around the inner wall of the gathering disk 407, and the handle 408 is rotated to drive the auxiliary pull rope 401 to be continuously wound, thereby fixing the auxiliary pull rope 401. The arc surface of the fixed rod 351 is fixedly connected to two limiting rings 406. Both auxiliary pull ropes 401 pass through the inner wall of the limiting rings 406. The two limiting rings 406 limit the auxiliary pull ropes 401, so that the auxiliary pull ropes 401 are close to the fixed rod 351, avoiding the auxiliary pull rope 401 from being cluttered and affecting mud extraction.

[0051] The effect achieved by the entire auxiliary structure 4 is that by pulling the two auxiliary pull ropes 401 at the upper end of the fixed stick 351, the auxiliary pull ropes 401 can be bent to the same position. By pulling the auxiliary pull ropes 401, full force can be exerted, and the connecting plate 352 at the lower end of the auxiliary pull rope 401 and the two semi-rotating disks 354 can be driven upward, and the two auxiliary pull ropes 401 are limited by the positioning wheel 404. When the auxiliary pull rope 401 is bent, the positioning wheel 404 can support it to prevent the auxiliary pull rope 401 from being limited and rubbing against the edge of the drill hole. When the auxiliary pull rope 401 is not needed, just wrap the two auxiliary pull ropes 401 around the inner wall of the focusing disk 407, and then turn the handle 408 to quickly wrap the auxiliary pull rope 401 around the focusing disk 407 for fixation, avoiding its disorderly placement.

[0052] Example 2, based on Example 1, Figure 2 and Figure 10As shown, the support structure 5 includes two support plates 501, one side of the support plate 501 is fixedly connected to the outer sleeve 1, and two fixed blocks 502 are fixedly connected to the upper surface of the outer sleeve 1 near the support plate 501. The inner part of the support plate 501 is slidably connected to a slider 504, and a slide groove 503 is provided on the upper surface of the support plate 501. A rectangular plate 505 is fixedly connected to the upper surface of the slider 504 near the slide groove 503, and cross plates 506 are fixedly connected to both sides of the rectangular plate 505. The inner thread of the rectangular plate 505 is connected to a screw 507, one end of the screw 507 is rotatably connected to the fixed block 502, and the other end of the screw 507 is fixedly connected to the handrail, and the inner part of the slider 504 is slidably connected to a steel nail 508. When the outer sleeve 1 is placed into the borehole, the two support plates 501 on its arc surface are used to support the two sides of the borehole and fix the outer sleeve 1. The handrail can then be rotated to drive the screw 507 to rotate and adjust the rectangular plate 505 on the arc surface of the screw 507 to adjust the front and rear position, driving the slider 504 below the rectangular plate 505 to extend outward within the support plate 501. The slider 504 extends to a certain length to avoid the soft ground close to the borehole, which makes it inconvenient to fix. Then, steel nails 508 are driven into the slider 504 and driven into the hard ground, thereby fixing the outer sleeve 1 and making the mud extraction of the outer sleeve 1 more stable. The lower surface of the slider 504 and the support plate 501 are fixedly connected to two spikes 509, and the sizes of the two spikes 509 are adapted. The spikes 509 can simultaneously penetrate the ground, thereby making the fixation of the slider 504 and the support plate 501 more stable and enhancing the stability of mud extraction.

[0053] The effect achieved by the entire support structure 5 is that after the outer sleeve 1 is placed in the drilled hole, the two support plates 501 on the arc surface can be supported on the outside of the drilled hole, thereby supporting the outer sleeve 1 and facilitating subsequent work. Then, the armrest is rotated to rotate the screw 507, and the screw 507 rotates on one side of the fixed block 502, and drives the rectangular plate 505 on its arc surface to move, so that the rectangular plate 505 drives the slider 504 at its lower end to slide out from the support plate 501, and the horizontal plate 506 is used to The rectangular plate 505 is limited at the upper end, so that it cooperates with the slider 504 to prevent the rectangular plate 505 from moving up and down, making its operation more stable. After the slider 504 slides out, the support distance of the support plate 501 is extended, and the soil away from the drill hole is harder, so the support effect is better. Then the slider 504 and the spikes 509 at the lower end of the support plate 501 can be inserted into the ground for fixation, and steel nails 508 can be driven into the ground from the inside of the slider 504 to enhance the fixing effect and make the extraction process of mud mixed water more stable.

[0054] The overall working principle is that when mud needs to be extracted, the outer sleeve 1 is first inserted inwardly into the mud drill hole to be extracted, and the inner sleeve 2 is inserted into the drill hole together with the outer sleeve. At this time, the spring 34 is in a completely relaxed state, and the inner protrusion 32 and the inner sleeve 2 are lifted up by one end, so that the inner sleeve 2 extends outward by one end of the outer sleeve 1. At this time, the outer water inlet hole 36 and the inner water inlet hole 37 are staggered, and the inner water inlet hole 37 is located at the upper end of the outer water inlet hole 36. After the outer sleeve 1 is inserted downward, since the outer water inlet hole 36 and the inner water inlet hole 37 are staggered, the mud mixed water in the drill hole cannot enter the interior of the inner sleeve 2. The cam 352 is pressed against the bottom of the inner sleeve 2 and the cam 353 is pressed against the bottom of the inner sleeve 2. The cam 353 is pressed against the bottom of the inner sleeve 2 and the cam 353 is pressed against the bottom of the inner sleeve 2. The plurality of inner water inlet holes 37 move downward, and when the inner water inlet holes 37 move downward to a position where they coincide with the outer water inlet holes 36, the two coincide and an opening is opened. At this time, the mud mixed water outside the outer sleeve 1 will flow inward from the opening, and the mud mixed water passes through the outer water inlet holes 36 and the inner water inlet holes 37 in succession, and then reaches the interior of the inner sleeve 2. The mud water continues to flow in, causing the overall weight of the inner sleeve 2 to continue to increase. At this time, the pressing and fixing rod 351 can be released. After the mud water completely flows into the inner sleeve 2, the inner sleeve 2 continues to sink due to its weight and compresses the spring 34. In this process, the position of the inner water inlet holes 37 is It continues to move downward until it completely passes through the outer water inlet hole 36, and the two are staggered again. At this time, the inner water inlet hole 37 is located at the lower end of the outer water inlet hole 36, so that the opening is closed, and then the mud water cannot flow into the inner sleeve 2. At this time, the fixed rod 351 can be pulled upward to drive the connecting plate 352 and the semi-rotating disk 354 at the lower end to lift the mud mixed water upward and completely extract the mud inside the inner sleeve 2. The inner sleeve 2 with reduced weight will continue to rise to the initial position under the action of the rebound force of the spring 34, waiting for the next cycle. After multiple cycles, the mud water and solid mud in the borehole can be completely extracted.

[0055] When the fixed rod 351 is subsequently lifted, the half-rotating disk 354 will not rotate downward due to the inverted "T"-shaped obstruction of the lower end of the connecting plate 352, thereby ensuring the efficient and stable extraction of mud.

[0056] When the auxiliary pull rope 401 needs to be lifted upward, since the fixing rod 351 is in a fixed state, it is in the center position of the inner sleeve 2, and the worker needs to jump out of the body, but he cannot fully exert force by jumping out of the body. At this time, the two auxiliary pull ropes 401 at the upper end of the fixing rod 351 can be pulled, and the auxiliary pull ropes 401 can be bent to the same position. By pulling the auxiliary pull rope 401, full force can be exerted, and the connecting plate 352 at the lower end of the auxiliary pull rope 401 and the two semi-rotating disks 354 can be lifted upward, and the two auxiliary pull ropes 401 are limited by the positioning wheels 404. When the auxiliary pull ropes 401 are bent, the positioning wheels 404 can support them to prevent the auxiliary pull ropes 401 from rubbing against the edge of the drill hole due to lack of limit. When the auxiliary pull ropes 401 are not needed, only the two auxiliary pull ropes 401 need to be wound around the inner wall of the tightening disk 407, and then the handle 408 can be turned to quickly wind the auxiliary pull ropes 401 around the tightening disk 407 for fixation, avoiding their disorderly placement.

[0057] After the outer sleeve 1 is placed in the borehole, the two support plates 501 on its arc surface can be supported on the outside of the borehole, thereby supporting the outer sleeve 1 and facilitating subsequent work. Subsequently, the handrail is rotated to rotate the screw 507, and the screw 507 rotates on one side of the fixed block 502, and drives the rectangular plate 505 on its arc surface to move, so that the rectangular plate 505 drives the slider 504 at its lower end to slide out from the support plate 501. The cross plate 506 is used to limit the upper end of the rectangular plate 505, thereby cooperating with the slider 504 to prevent the rectangular plate 505 from moving up and down, making its work more stable. After the slider 504 slides out, the supporting distance of the support plate 501 is extended, and the soil away from the borehole is harder, so the supporting effect is better. Subsequently, the slider 504 and the spikes 509 at the lower end of the support plate 501 can be inserted into the ground for fixation, and steel nails 508 are driven into the ground from the inside of the slider 504 to strengthen the fixing effect and make the extraction process of mud mixed water more stable.
