Abstract
Description
Technical Field
[0001] This invention relates to the field of pile foundation construction technology, and in particular to a pile foundation construction platform. Background Technology
[0002] Mud-wall bored piles are formed by slowly drilling with a pile driver under mud-wall conditions, using mud to carry out the drill cuttings and protect the borehole wall from collapse. After the hole is formed, underwater concrete is poured to replace the mud.
[0003] As the drilling rig continues to excavate and drill, mud carrying drill cuttings is continuously discharged from inside the casing and flows into the sedimentation tank through the sewage pipe. The mud contains gravel and other debris, which can easily clog the sewage pipe. In addition, some mud that is not discharged in time flows to the ground. At this time, although the ground has been leveled, the surface has not been poured with concrete. The mud flowing to the ground gradually seeps into the soil layer, resulting in excessive water content in the soil layer around the borehole, making the ground muddy and difficult for workers to walk on. Furthermore, the stability of the soil layer around the borehole deteriorates, which is not conducive to the construction of drilling rigs and other machinery.
[0004] Therefore, it is necessary to provide a new pile foundation construction platform to solve the above-mentioned technical problems. Summary of the Invention

[0015] Compared with related technologies, the pile foundation construction platform provided by this invention has the following beneficial effects:
[0016] This invention provides a pile foundation construction platform. After the casing is pressed into the leveled soil layer, a concrete layer is poured on the surface of the soil layer. The casing is located in the center of the groove. During the drilling process, the drilling rig stops on the surface of the concrete layer. The concrete layer has strong surface stability, which improves the stability of the drilling rig and other mechanical construction, reduces the probability of the drilling rig overturning, and during the drilling process, the drilling mud carrying drill cuttings is discharged from the casing and remains inside the groove, preventing the mud from flowing to the ground, thus facilitating the extraction of mud and improving the stability of the soil layer around the casing.
[0017] When the drilling mud enters the groove through the casing, under the influence of gravity, large pieces of gravel carried by the mud settle around the casing, and the retaining mechanism keeps these large pieces of gravel inside the groove to prevent them from clogging the pipe. The drilling mud carries small pieces of drill cuttings towards the fixed cylinder. The turbine rotates rapidly inside the fixed cylinder, creating suction on the side walls of the fixed cylinder and the support mesh. The upper layer of drilling mud penetrates the support mesh and enters the interior of the fixed cylinder. Under the influence of gravity, the drill cuttings gradually accumulate at the bottom of the fixed cylinder. The rotating plate rotates below the fixed cylinder, stirring up the brick debris settled at the bottom of the fixed cylinder, facilitating the entry of the drill cuttings carrying the drilling mud into the interior of the fixed cylinder. The crushing rod is installed at the bottom of the fixed cylinder. The crushing rod rotates rapidly and contacts and crushes the small pieces of drill cuttings. The spiral fan blades rotate rapidly counterclockwise. The turbine propels the broken drill cuttings and mud upwards rapidly, and its rotation drives the drill cuttings and mud to be discharged quickly through the drain pipe, thereby improving the discharge efficiency of the mud and drill cuttings and preventing the fixed cylinder from being easily blocked. During the drainage process, the drive mechanism drives the scraper downwards. The scraper moves downwards along the side walls of the fixed cylinder and the support mesh. As the scraper gradually covers the surface of the support mesh, the area of the support mesh that filters the mud decreases, reducing the speed at which the mud enters the fixed cylinder. This suddenly increases the suction at the bottom of the fixed cylinder, causing the bottom of the fixed cylinder to draw the drill cuttings deposited at the bottom of the groove into the interior of the fixed cylinder, facilitating the crushing of the drill cuttings. Furthermore, as the scraper slides along the side wall of the support mesh, it removes the mud adsorbed on the surface of the support mesh, preventing the support mesh from becoming blocked, thereby quickly cleaning the mud and drill cuttings.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 . Figure 1 This is a structural schematic diagram of the pile foundation construction platform provided by the present invention; Figure 2 for Figure 1 The diagram shows an enlarged view of the structure at point A. Figure 3 for Figure 2 The diagram shows an enlarged view of the structure at point B. Figure 4 for Figure 1 The diagram shows an enlarged view of the structure at point C.

Figure 7 for Figure 2 The diagram shows the internal structure of the drive mechanism. Figure 8 for Figure 2The diagram shows the internal structure of the reinforcement mechanism. The pile foundation construction platform includes: a soil layer 1; and a platform body 2. The platform body 2 includes a concrete layer 21, grooves 22, a first fixing plate 26, a second fixing plate 27, and a casing 28. The casing 28 is embedded inside the soil layer 1, and the concrete layer 21 is poured onto the surface of the soil layer 1. The surface of the concrete layer 21 has multiple frustum-shaped grooves 22. The first fixing plate 26 is symmetrically fixed to the surface of the concrete layer 21 by bolts, and the second fixing plate 27 is symmetrically fixed to the surface of the first fixing plate 26 by bolts. The platform body 2 also includes boreholes 23, drill bits 24, and a reinforcing cage 25. Multiple boreholes 23 are provided inside the soil layer 1, and the drill bits 24 for excavating the boreholes 23 are installed inside the casing 28. The casing 28 and the boreholes 23 are connected internally... The reinforcing cage 25 is placed in the center of the groove 22, the borehole 23, and the casing 28, with the center lines of the groove 22, the borehole 23, and the casing 28 extending into the center of the groove 22. After the casing 28 is pressed into the leveled soil layer 1, a concrete layer 21 is poured on the surface of the soil layer 1. The casing 28 is located in the center of the groove 22. During the drilling process, the drilling rig stops on the surface of the concrete layer 21. The surface of the concrete layer 21 has strong stability, which improves the stability of the drilling rig and other mechanical construction, reduces the probability of the drilling rig overturning, and the drilling mud carrying drill cuttings is discharged from the casing 28 and remains inside the groove 22, preventing the mud from flowing to the ground, thus facilitating the extraction of mud and improving the stability of the soil layer around the casing 28. After the cast-in-place pile is constructed, the spliced steel bars of the cast-in-place pile are connected to the spliced steel bars inside the concrete layer 21, and then concrete is poured inside the groove 22 so that the cast-in-place pile and the concrete layer 21 form a whole.
[0029] The cleaning mechanism 3 includes a support net 31, a motor 32, a sewage pipe 33, a turbine 34, a fan blade 35, a fixed cylinder 36, a bracket 37, a crushing rod 38, a rotating plate 39, and a fixed shaft 310. The fixed cylinder 36 and the bracket 37 are placed inside the groove 22. The bracket 37 is installed at the bottom of the fixed cylinder 36, and the support net 31 for sucking up mud is installed on the side wall of the fixed cylinder 36. The sewage pipe 33 is installed at the top of the fixed cylinder 36, and the sewage pipe 33 connects to a sedimentation tank 11 located inside the soil layer 1 for storing mud. The motor 32 for driving the fixed shaft 310 to rotate is installed at the top of the fixed cylinder 36. The turbine 34 for discharging sewage, the fan blade 35 for pushing sewage upwards, the crushing rod 38 for crushing drill cuttings, and the rotating plate 39 for preventing drill cuttings accumulation are installed on the side wall of the fixed shaft 310. The fan blade 35 is spiral-shaped. The motor 32 drives the turbine 34 to rotate rapidly counterclockwise inside the fixed cylinder 36, causing suction to be generated on the side walls of the fixed cylinder 36 and the support net 31. The upper layer of mud inside the groove 22 penetrates the support net 31 and enters the interior of the fixed cylinder 36. Under the action of gravity, the drill cuttings gradually gather at the bottom of the fixed cylinder 36. The rotating plate 39 rotates below the fixed cylinder 36, stirring up the brick debris that has settled at the bottom of the fixed cylinder 36, making it easier for the drill cuttings to carry the mud into the interior of the fixed cylinder 36. The crushing rod 38 is installed at the bottom of the fixed cylinder 36. The crushing rod 38 rotates rapidly and contacts small pieces of drill cuttings to crush them. The spiral fan blade 35 rotates rapidly counterclockwise, pushing the crushed drill cuttings and mud upwards. The turbine 34 rotates and pushes the drill cuttings and mud out quickly through the drain pipe 33, thereby improving the discharge efficiency of mud and drill cuttings and preventing the fixed cylinder 36 from being easily blocked.
[0030] A drive mechanism 5 is connected to the adjustment mechanism 6 and the reinforcement mechanism 4. The drive mechanism 5 includes a mounting box 51, a stepper motor 52, a screw 53, a first gear 54, and a second gear 55. The top end of the fixed cylinder 36 is fixedly connected to the mounting box 51. The first gear 54 and the second gear 55 are rotatably connected and meshed inside the mounting box 51. The stepper motor 52, which drives the second gear 55 to rotate, is mounted on the side wall of the mounting box 51. The first gear 54 is threadedly connected to the screw 53, and the top end of the screw 53 abuts against the side wall of the baffle 47 and the support plate 41. When the stepper motor 52 operates, it drives the second gear 55 to rotate. The diameter of the first gear 54 is larger than the diameter of the second gear 55, making it easier for the second gear 55 to drive the first gear 54 to rotate. The first gear 54 is threadedly connected to the screw 53. Using the principle of helical transmission, the first gear 54 drives the screw 53 to move up and down.
[0031] An adjusting mechanism 6 includes a scraper 61, a support rod 62, a fixing sleeve 63, and a limiting rod 64. The cylindrical scraper 61 is slidably connected to the side walls of the support mesh 31 and the fixing cylinder 36. The two ends of the support rod 62 are respectively fixedly connected to the scraper 61 and the fixing sleeve 63, and the side wall of the fixing sleeve 63 is threadedly connected to the limiting rod 64. The screw 53 is slidably connected to the fixing sleeve 63, and the limiting rod 64 abuts against the side wall of the screw 53. When the limiting rod 64 on the side wall of the fixing sleeve 63 is rotated, the limiting rod 64 rotates and presses against the side wall of the screw 53, thereby fixing the screw 53 to the side wall of the fixing sleeve 63. When the screw 53 moves downward, it drives the support rod 62 and the scraper 61 to move downward. The scraper 61 moves downward along the sidewalls of the fixed cylinder 36 and the support net 31. As the scraper 61 gradually covers the surface of the support net 31, the height of the support net 31 is greater than the height of the scraper 61. The scraper 61 will not completely cover the support net 31, but the area of the support net 61 that filters the mud is reduced, thus reducing the speed at which the mud enters the fixed cylinder 36. This suddenly increases the suction at the bottom of the fixed cylinder 36, causing the bottom of the fixed cylinder 36 to suck the drill cuttings deposited at the bottom of the groove 22 into the interior of the fixed cylinder 36, facilitating the crushing of the drill cuttings. Furthermore, as the scraper 61 slides along the sidewalls of the support net 31, it removes the mud adsorbed on the surface of the support net 31, preventing the support net 31 from becoming clogged, thereby quickly cleaning the mud and drill cuttings.
[0032] The diameter of the support net 31 is equal to the minimum diameter of the fixed cylinder 36, so as to facilitate the movement of the scraper 61 on the side walls of the support net 31 and the fixed cylinder 36; the top of the fixed cylinder 36 has an annular structure so as to facilitate the rotation of the turbine 34 to push the mud out of the interior of the fixed cylinder 36 quickly; the bottom of the fixed cylinder 36 has a funnel-shaped structure so as to facilitate the entry of drill cuttings into the bottom of the fixed cylinder 36.
[0033] A containment mechanism 7 is installed at the bottom of the drive mechanism 5. The containment mechanism 7 includes a stop bar 71, a breaking tooth 72, and a connecting rod 73. The stop bars 71 are installed on the bottom surface of the mounting box 51 in an arc shape, and the connecting rods 73 are fixedly connected between adjacent stop bars 71. The breaking tooth 72 is provided on one side of the stop bar 71 for breaking the drill cuttings, and the top of the breaking tooth 72 is connected to the screw 53. The stop bar 71 surrounds the fixed cylinder 36 to prevent the open drill cuttings in the mud from contacting the fixed cylinder 36, reducing the probability of blockage of the fixed cylinder 36. The screw 53 drives the breaking tooth 72 to move downward, so that the breaking tooth 72 crushes large pieces of drill cuttings.
[0034] A reinforcing mechanism 4 is rotatably connected to the second fixing plate 27 and connected to the sewage pipe 33. The reinforcing mechanism 4 includes a support plate 41, a first connecting pipe 43, a sheath 44, a second connecting pipe 46, a baffle 47, and a piston 410. The side wall of the second fixing plate 27 is rotatably connected to the support plate 41, and the baffle 47 is installed on one side of the support plate 41. Multiple first connecting pipes 43 are installed on the side wall of the support plate 41, and the interior of each first connecting pipe 43 is slidably connected to the second fixing plate 27. The connecting pipe 46 and the piston 410 are respectively installed at both ends of the second connecting pipe 46, which is used to drive the second connecting pipe 46 to move and the sleeve 44 is used to provide support for the steel cage 25. In order to facilitate the upward movement of the screw 53 to squeeze the support plate 41 and make the support plate 41 rotate upward, the screw 53 moves to abut against the baffle 47, thereby providing support for the baffle 47 and the support plate 41, so that the support plate 41 is inclined on the surface of the second fixed plate 27;
[0035] The reinforcement mechanism 4 further includes a cylinder 42, a connecting pipe 45, a compression plate 48, and springs 49. The cylinder 42, which is used to supply hydraulic oil into the first connecting pipe 43, is mounted on the surface of the second fixing plate 27. The bottom end of the cylinder 42 is fitted with the connecting pipe 45, which is used to connect with the drain pipe 33. The compression plate 48, which is used to compress the hydraulic oil inside the cylinder 42, is slidably connected inside the cylinder 42. The two ends of the multiple springs 49 are respectively connected to the compression plate 48 and the cylinder 42. The valve on the side wall of the connecting pipe 45 is opened, and the drain pipe is closed. The valve on the side wall of pipe 33 allows the slurry inside the sewage pipe 33 to enter the interior of the cylinder 42 through the connecting pipe 45, thereby pushing the compression plate 48 inside the cylinder 42 to move upward and squeeze the spring 49. At the same time, the compression plate 48 squeezes hydraulic oil into the interior of the first connecting pipe 43, pushing the piston 410, the second connecting pipe 46, and the sheath 44 towards the direction of the reinforcing cage 25. The sheath 44 squeezes and abuts against the side wall of the reinforcing cage 25 to prevent the reinforcing cage 25 from shifting its position when placed in the drill hole 23.
[0036] The working principle of the pile foundation construction platform provided by this invention includes the following steps: After the casing 28 is pressed into the leveled soil layer 1, a concrete layer 21 is poured on the surface of the soil layer 1, leaving a groove 22 around the casing 28. The first fixing plate 26 is then fixed to the surface of the concrete layer 21 using bolts, and the second fixing plate 27 is then fixed to the surface of the first fixing plate 27 using bolts. The first fixing plate 26 and the second fixing plate 27 are interwoven on the surface of the groove 22, thus facilitating construction by workers. The device is connected to an external power source, and a drilling rig is used to excavate a hole inside the casing 28 while injecting mud. During the drilling process, the mud carrying the drill cuttings is discharged from inside the casing 28 into the interior of the groove 22. At this time, the motor 32 drives the fixed shaft 310 and the turbine 34 to rotate rapidly. The upper layer of mud inside the groove 22 penetrates the support net 31 and enters the interior of the fixed cylinder 36. The crushing rod 38 rotates rapidly to crush the drill cuttings, and the fan blade 35 rotates rapidly counterclockwise to push the crushed drill cuttings and mud upwards. The turbine 34 rotates to push the drill cuttings and mud through the drain pipe 33 to be quickly discharged into the interior of the sedimentation tank 11. During the mud movement, because the baffle 71 surrounds the fixed cylinder 36, the drill cuttings in the mud are blocked by the baffle 71 and do not come into contact with the fixed cylinder 36, reducing the probability of the fixed cylinder 36 becoming clogged. Every five minutes, the stepper motor 52 is turned on, causing the stepper motor 52 to drive the screw 53, the scraper 61 and the crushing tooth 72 to move up and down once. When the scraper 61 moves to the bottom, it stays for one or two minutes and then returns to its original position. The movement of the scraper 61 removes the mud adsorbed on the surface of the support net 31, while increasing the suction at the bottom of the fixed cylinder 36. At the same time, the crushing tooth 72 crushes large pieces of drill cuttings, making it easier for the drill cuttings to enter the interior of the fixed cylinder 36 for further crushing.When hoisting the reinforcing cage 25, separate the limiting rod 64 from the screw 53, hoist the reinforcing cage 25 into the drilled hole 23 at the predetermined installation position, turn on the stepper motor 52 to make the screw 53 move upward to press the support plate 41, causing the support plate 41 to rotate upward. The screw 53 moves to abut against the baffle 47, thereby providing support for the baffle 47 and the support plate 41, so that the support plate 41 is tilted on the surface of the second fixing plate 27. Open the valve on the side wall of the connecting pipe 45 and close the side wall of the sewage pipe 33. The valve allows the slurry inside the drain pipe 33 to enter the interior of the cylinder 42 through the connecting pipe 45, thereby pushing the compression plate 48 inside the cylinder 42 to move upward and squeeze the spring 49. At the same time, the compression plate 48 squeezes hydraulic oil into the interior of the first connecting pipe 43, pushing the piston 410, the second connecting pipe 46, and the sheath 44 toward the direction of the reinforcing cage 25. The sheath 44 presses against the side wall of the reinforcing cage 25 to prevent the reinforcing cage 25 from shifting its position when placed in the drill hole 23.
