Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology, and in particular to a cement-mixed soil reinforced pile implantation device for foundation pits in silty sand layers. Background Technology

[0002] The cement-mixed soil reinforcement pile implantation device for silty sand foundation pits is a specialized piece of equipment used in the construction of silty sand foundation pits to implant reinforcement piles into cement-mixed soil. It mainly includes a mixing pile power head, clutch, hydraulic station, turntable, and mixing rod. The turntable drives the mixing rod to rotate, thereby mixing cement slurry or cement powder with the silty sand layer in situ to form columnar cement-soil bodies, which play a role in reinforcing the foundation and preventing water seepage.

[0003] A search revealed Chinese patent publication number CN211735432U, which discloses a steel mesh fixing structure for bored piles. The structure includes: multiple transverse reinforcing bars, each end of which is embedded into a retaining pile; multiple longitudinal reinforcing bars, which are welded and fixed to the transverse reinforcing bars; a steel mesh, attached to the inner side of the transverse and longitudinal reinforcing bars, facing the soil between the piles; J-shaped anchor bars, with a long straight section embedded in the soil between the piles and a bent section passing through the steel mesh and hooking the transverse and longitudinal reinforcing bars; the insertion holes of the J-shaped anchor bars in the soil between the piles are filled with mortar for fixation; and fine aggregate concrete, sprayed onto the outer side of the transverse and longitudinal reinforcing bars and the steel mesh, facing the pit. This detailed joint treatment of the pile support can significantly improve the stability and safety of the pile foundation retaining wall, effectively fix the soil between the piles, and ensure the safety of the pit support and the overall stability of the pit.

[0004] In the prior art, a cement-mixed soil rebar pile implantation device for foundation pits in silty soil layers is used in silty soil layers rich in fine sand particles. During construction, the drill bit is prone to wear due to long-term friction with the sand particles. Furthermore, different types of drill bits need to be replaced when drilling in different terrains. Replacing the drill bit requires cumbersome steps such as bolt removal and hoisting for alignment, which increases replacement time and reduces drilling efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cement-mixed soil reinforced pile implantation device for foundation pits in silty sand layers. It aims to solve the problem in the prior art that the drill bit is easily worn due to long-term friction with sand particles during construction, which leads to the need for cumbersome steps such as bolt disassembly and hoisting alignment to replace the drill bit, thereby increasing the drill bit replacement time and reducing drilling efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cement-mixed soil reinforced pile implantation device for a silty sand foundation pit, comprising a drill bit, an auger rod disposed on the inner wall of the drill bit, a push block slidably connected to the outer wall of the auger rod, a spring I disposed on the inner wall of the drill bit, a locking block fixedly connected to the top of the spring I, the outer wall of the locking block rotatably connected to the inner wall of the drill bit, the outer wall of the locking block slidably connected to the inner wall of the push block, the outer wall of the locking block locking onto the inner wall of the auger rod, a guide block rotatably connected to the inner wall of the auger rod, a tension spring disposed on the outer wall of the guide block, the outer wall of the guide block slidably connected to the inner wall of the drill bit, a spring II disposed on the inner wall of the guide block, a limit block fixedly connected to the outer wall of the spring II, the outer wall of the limit block slidably connected to the inner wall of the guide block, a fixing block locking onto the outer wall of the limit block, the inner wall of the fixing block disposed on the outer wall of the drill bit, and a spraying assembly disposed on the outer wall of the auger rod.

[0007] The above technical solution involves installing different types of drill bits onto the outer wall of the auger rod. A spring installed on the inner wall of the drill bit pushes a locking block to secure the auger rod. The locking block rotates on the inner wall of the drill bit, preventing it from falling off. After the locking block secures the auger rod, a pusher block with a hollow groove is installed on the inner wall of the locking block, preventing it from falling off during drilling. When the pusher block with its angled section slides on the outer wall of the locking block, it quickly releases the self-locking mechanism. The auger rod then drives a guide block to slide on the inner wall of the drill bit, causing the guide block to rotate on the inner wall of the auger rod. At the same time, the tension spring pulls the guide block to center, which can limit the guide block. The guide block drives the limit block to slide on the outer wall of the upper fixed block. After the guide block slides to the appropriate position, the spring installed on the inner wall of the guide block will push the limit block to lock the upper fixed block. The upper fixed block is fixed to the inner wall of the drill bit, which can make the guide block achieve a self-locking effect. When it is necessary to release the self-locking, push the guide block to drive the limit block to slide to the lower surface of the lower fixed block. Pull the guide block to make the limit block drive the lower fixed block to slide synchronously. When the upper and lower sides are in contact, the limit block will disengage from the fixed block, which can quickly release the self-locking effect.

[0008] As a further description of the above technical solution:

[0009] The spraying assembly includes a mud spraying head, the inner wall of which is fixedly connected to the outer wall of the auger drill rod. A support pile is provided on the outer wall of the drill bit. The outer wall of the auger drill rod is rotatably connected to the inner wall of the support pile. A guide plate is slidably connected to the outer wall of the support pile. A material feeding assembly is provided on the outer wall of the guide plate.

[0010] The above technical solution allows the support pile to slide on the outer wall of the guide plate, while the guide plate is fixed on the inner wall of the base, thus preventing the support pile from shifting. When the drill bit drills, it will drive the support pile to slide synchronously, causing the auger drill rod to drive the mud spraying head to rotate synchronously, enabling the drill bit to achieve the effect of mixing and discharging cement during the drilling process.

[0011] As a further description of the above technical solution:

[0012] The feeding assembly includes a base, the inner wall of which is fixedly connected to the outer wall of the guide plate, an electric push rod fixedly connected to the outer wall of the base, a feeding block fixedly provided at the output end of the electric push rod, and the outer wall of the feeding block slidably connected to the inner wall of the base.

[0013] The above technical solution allows the material block to slide on the inner wall of the base by being pushed by an electric push rod fixed to the outer wall of the base, thus achieving a stable sliding effect. By pushing the material block to the drill inlet by the electric push rod, the material block can achieve a stable placement of I-shaped steel rebar piles or steel pipe piles, while also reducing the vertical deviation of the pile body.

[0014] As a further description of the above technical solution:

[0015] A baffle is fixedly connected to the upper surface of the feeding block, and a storage block is fixedly connected to the upper surface of the base.

[0016] The above technical solution involves installing the storage block onto the upper surface of the base, and then placing the I-shaped steel reinforcement piles or steel pipe piles into the interior of the storage block. This allows the I-shaped steel reinforcement piles or steel pipe piles to pass through the storage block and enter the interior of the material feeding block. The sliding of the material feeding block will cause the baffle to block the storage block, thus enabling the material feeding block to achieve a quantitative feeding effect.

[0017] As a further description of the above technical solution:

[0018] A guide plate is fixedly connected to the upper surface of the base, the upper surface of the unloading block is slidably connected to the lower surface of the guide plate, and a support component is provided on the upper surface of the unloading block.

[0019] The above technical solution involves installing a guide plate onto the upper surface of the material block, allowing the material block to slide on the inner wall of the guide plate, and the guide plate to slide on the inner wall of the guide plate. This allows the guide plate to prevent deviation while guiding the material block.

[0020] As a further description of the above technical solution:

[0021] The support assembly includes a rack, the outer wall of which is fixedly connected to the upper surface of the feed block, and the outer wall of which is slidably connected to the inner wall of the guide plate.

[0022] The above technical solution involves using an electric push rod to slide the material block, which in turn causes the rack to slide synchronously. This allows the rack to reciprocate, and by sliding the rack against the inner wall of the guide plate, it prevents the rack from falling off.

[0023] As a further description of the above technical solution:

[0024] The rack has a gear meshing at the tooth end on one side, a fixing rod fixedly connected to the inner wall of the gear, and the outer wall of the fixing rod rotatably connected to the inner wall of the guide plate. The gear on the other side has a push-pull rod meshing at the tooth end, and the outer wall of the push-pull rod slidably connected to the inner wall of the guide plate.

[0025] The above technical solution involves a rack driving a gear on one side to rotate, with the gear fixed to the outer wall of a fixed rod. The fixed rod rotates on the inner wall of a guide plate, enabling the gear to achieve stable transmission. The rotation of the fixed rod drives the gear on the other side to rotate, causing the gear on the other side to drive the push-pull rod to slide synchronously. When the rack is pulled back, the push-pull rod is pushed out, and when the rack is pushed out, the push-pull rod is retracted, achieving the effect of stably pushing the I-shaped steel pile or steel pipe pile.

[0026] As a further description of the above technical solution:

[0027] The outer wall of the push-pull rod is slidably connected to a limiting tube, and the outer wall of the limiting tube is fixedly connected to the inner wall of the guide plate.

[0028] The above technical solution allows the push-pull rod to slide on the inner wall of the limiting tube, while the limiting tube is fixed to the inner wall of the guide plate. This ensures a stable push-pull effect.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, by installing the drill bit into the spiral drill rod, the spiral drill rod drives the spring to slide on the inner wall of the drill bit, which in turn drives the limiting block to slide synchronously. This allows the limiting block to lock the fixing block. The drill bit drives the locking block to lock the spiral drill rod, and the push block is pushed to fix the locking block. The guide block can quickly replace and install different types of drill bits, making the equipment adaptable to different terrains, thus shortening the replacement time and improving drilling efficiency.

[0031] 2. In this utility model, the electric push rod pushes the material block to slide, so that the material block drives the rack to slide while driving the gear on one side to rotate further, and the gear on the other side will drive the push-pull rod to slide on the inner wall of the limiting tube. The material block can achieve the effect of quantitatively dispensing different piles, and the push-pull rod can stably insert different piles to achieve the effect of preventing pile displacement.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a cement-mixed soil reinforced pile implantation device for a silty sand foundation pit, comprising a drill bit 1, a spiral drill rod 11 disposed on the inner wall of the drill bit 1, a push block 12 slidably connected to the outer wall of the spiral drill rod 11, a spring 13 disposed on the inner wall of the drill bit 1, a locking block 14 fixedly connected to the top of the spring 13, the outer wall of the locking block 14 rotatably connected to the inner wall of the drill bit 1, the outer wall of the locking block 14 slidably connected to the inner wall of the push block 12, the outer wall of the locking block 14 locking into the inner wall of the spiral drill rod 11, a guide block 15 rotatably connected to the inner wall of the spiral drill rod 11, a tension spring 16 disposed on the outer wall of the guide block 15, and the outer wall of the guide block 15 slidably connected to the inner wall of the drill bit 1. The inner wall of the guide block 15 is provided with a spring 17. The outer wall of the spring 17 is fixedly connected to a limit block 18. The outer wall of the limit block 18 is slidably connected to the inner wall of the guide block 15. The outer wall of the limit block 18 is engaged with a fixing block 19. The fixing block 19 is provided on the outer wall of the drill bit 1. The outer wall of the spiral drill rod 11 is provided with a spraying assembly 2. The spraying assembly 2 includes a mud spraying head 21. The inner wall of the mud spraying head 21 is fixedly connected to the outer wall of the spiral drill rod 11. The outer wall of the drill bit 1 is provided with a support pile 22. The outer wall of the spiral drill rod 11 is rotatably connected to the inner wall of the support pile 22. The outer wall of the support pile 22 is slidably connected with a guide plate 23. The outer wall of the guide plate 23 is provided with a feeding assembly 3.

[0041] Specifically, different types of drill bits 1 are installed on the outer wall of the auger drill rod 11 according to different terrains. The auger drill rod 11 drives the guide block 15 to be installed on the inner wall of the drill bit 1. At the same time, the rotation of the guide block 15 will pull the tension spring 16, which provides the power for the guide block 15 to return to its original position. When the spring 17 drives the limiting block 18 to slide to the upper fixing block 19, since the upper fixing block 19 is fixed to the inner wall of the drill bit 1, the fixing block 19 pushes the limiting block 18 and compresses the spring 17. When the guide block... After the guide block 15 slides to the appropriate position, the second spring 17 will push the limit block 18 to lock the fixing block 19, achieving a quick self-locking effect. When the self-locking is released, the limit block 18 is pushed to slide to the lower surface of the lower fixing block 19. Then, the guide block 15 is pulled to make the limit block 18 drive the lower fixing block 19 to slide synchronously, allowing the limit block 18 to quickly release the self-locking effect. When the guide block 15 self-locks, the first spring 13 installed on the inner wall of the drill bit 1 will push the locking block 14 to lock the spiral drill rod 11. Rotating on the inner wall of drill bit 1 prevents the chuck 14 from falling off while quickly fixing the auger rod 11. After the chuck 14 fixes the auger rod 11, it pushes the push block 12, which slides on the outer wall of the auger rod 11, so that the part of the push block 12 with a hollow groove locks the chuck 14, thus preventing the chuck 14 from falling off the auger rod 11. When the push block 12 with an inclined angle slides on the outer wall of the chuck 14, the chuck 14 can be quickly released. By installing the support pile 22 on the outer wall of drill bit 1, the support pile 22 moves synchronously when drill bit 1 moves, and the support pile 22 slides on the outer wall of guide plate 23, which can make the support pile 22 slide stably while preventing deviation. Installing the mud spraying head 21 on the outer wall of auger rod 11 can facilitate the synchronous spraying of cement. The guide block 15 can quickly replace and install different types of drill bits 1, making the equipment adaptable to different terrains, shortening replacement time and improving drilling efficiency.

[0042] Reference Figure 1 and Figure 4 The feeding assembly 3 includes a base 31, the inner wall of which is fixedly connected to the outer wall of the guide plate 23, an electric push rod 32 fixedly connected to the outer wall of the base 31, a feeding block 33 fixedly provided at the output end of the electric push rod 32, the outer wall of the feeding block 33 being slidably connected to the inner wall of the base 31, a baffle 34 fixedly connected to the upper surface of the feeding block 33, a storage block 35 fixedly connected to the upper surface of the base 31, a guide plate 36 fixedly connected to the upper surface of the base 31, the upper surface of the feeding block 33 being slidably connected to the lower surface of the guide plate 36, and a support assembly 4 provided on the upper surface of the feeding block 33.

[0043] Specifically, when it is necessary to place I-shaped steel rebar piles or steel pipe piles, first place the I-shaped steel rebar piles or steel pipe piles into the storage block 35, so that the I-shaped steel rebar piles or steel pipe piles enter the feeding block 33. At this time, the electric push rod 32 is activated to push the feeding block 33 to slide on the inner wall of the base 31, which can achieve the effect of preventing the feeding block 33 from deviating. The feeding block 33 drives the baffle 34 to slide, so that the baffle 34 will block the feeding port of the storage block 35, which can achieve the effect of quantitative feeding of the storage block 35. The guide plate 36 and the storage block 35 are fixed to the upper surface of the base 31, which can achieve the effect of limiting the position.

[0044] Reference Figure 1 , Figure 4 and Figure 5 The support component 4 includes a rack 41, the outer wall of which is fixedly connected to the upper surface of the feed block 33, the outer wall of which is slidably connected to the inner wall of the guide plate 36, a gear 42 on one side meshing with the tooth end of the rack 41, a fixing rod 43 on the inner wall of the gear 42, the outer wall of the fixing rod 43 being rotatably connected to the inner wall of the guide plate 36, a push-pull rod 44 on the other side meshing with the tooth end of the gear 42, the outer wall of the push-pull rod 44 being slidably connected to the inner wall of the guide plate 36, a limit tube 45 on the outer wall of the push-pull rod 44 being slidably connected to the outer wall of the push-pull rod 44, and the outer wall of the limit tube 45 being fixedly connected to the inner wall of the guide plate 36.

[0045] Specifically, when the material block 33 slides out, it causes the rack 41 to slide against the inner wall of the guide plate 36, causing the rack 41 to drive the gear 42 on one side to rotate. The gear 42 is fixed to the outer wall of the fixing rod 43, and the fixing rod 43 rotates against the inner wall of the guide plate 36. This allows the rack 41 to slide stably while achieving a stable transmission effect. The fixing rod 43 drives the gear 42 on the other side to rotate, causing the gear 42 to drive the push-pull rod 44 to slide. The push-pull rod 44 slides against the inner wall of the limiting tube 45, which prevents the push-pull rod 44 from falling off. As a result, the push-pull rod 44 is fixed to the inner wall of the guide plate 36 by the limiting tube 45, and slides on the inner wall of the guide plate 36, which can prevent the push-pull rod 44 from deviating. When the rack 41 is pushed, the push-pull rod 44 will slide to the inner wall of the limiting tube 45, which can prevent interference with the feeding of the material block 33. When the rack 41 is pulled, the push-pull rod 44 will be pushed out simultaneously, which can achieve the effect of stable implantation of I-shaped steel bar piles or steel pipe piles. The push-pull rod 44 can stably implant different pile bodies, which can prevent the pile body from deviating.

[0046] Working principle: When the device is needed, the drill bit 1 is installed on the outer wall of the spiral drill rod 11, causing the guide block 15 to drive the limiting block 18 to slide synchronously on the inner wall of the drill bit 1. The tension spring 16 pulls the guide block 15, while the second spring 17 pushes the limiting block 18 to lock the fixing block 19, achieving a rapid self-locking effect. At this time, the first spring 13 installed on the inner wall of the drill bit 1 pushes the locking block 14 to lock the spiral drill rod 11. Then, the push block 12 is installed on the outer wall of the locking block 14, allowing the locking block 14 to quickly fix the drill bit 1. As a result, after the support pile 22 passes through the guide plate 36, it slides on the outer wall of the guide plate 23, while the guide plate 23 is fixed on the inner wall of the base 31. When the drill bit 1 is installed on the inner wall of the support pile 22, the drill bit 1 and the support pile 22 can achieve the effect of preventing displacement, and the drill bit 1 can quickly detach from the support pile 22 for easy removal. When the drill bit 1 drills, the spiral drill rod 11 can discharge excess mud and sand and achieve the effect of mixing cement. The mud spraying head 21 fixed on the outer wall of the spiral drill rod 11 can achieve the effect of convenient cement discharge.

[0047] When drill bit 1 drills in, I-shaped steel bar piles or steel pipe piles can be put into storage block 35, so that the I-shaped steel bar piles or steel pipe piles can enter into material discharge block 33 through storage block 35. When drill bit 1 drills into the appropriate position, electric push rod 32 is activated to push material discharge block 33 to slide on the inner wall of base 31, so that material discharge block 33 can achieve stable feeding effect. When material discharge block 33 slides, it will drive baffle 34 to slide synchronously, so that baffle 34 blocks storage block 35, which can achieve quantitative feeding effect.

[0048] When the electric push rod 32 pulls back the material block 33, the material block 33 will drive the rack 41 to slide on the inner wall of the guide plate 36, so that the rack 41 drives the gear 42 on one side to rotate and simultaneously drives the fixed rod 43 to rotate, thereby allowing the gear 42 on the other side to drive the push-pull rod 44 to slide on the inner wall of the limit tube 45, which can achieve a stable pushing effect. By pushing the I-shaped steel pile or steel pipe pile into the cement through the push-pull rod 44, the stability of the retaining structure can be improved. This device can not only quickly replace and install different types of drill bits 1, making the equipment adaptable to different terrains, and shorten the replacement time while improving drilling efficiency, but also achieve the effect of quantitatively feeding different pile bodies. The push-pull rod 44 can stably implant different pile bodies, achieving the effect of preventing pile body displacement.

Although the present utility model 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.
