Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a concrete pouring device for deep-hole cast-in-place piles. Background Technology

[0002] In the field of building construction, deep-hole cast-in-place piles are a common foundation engineering construction method, widely used in the construction of important infrastructure such as high-rise buildings and bridge projects. During the construction of deep-hole cast-in-place piles, concrete pouring is a critical step, and its construction quality directly affects the safety and stability of the entire project.

[0003] Traditional methods for pouring concrete for deep-hole cast-in-place piles typically employ the tremie pipe method, where concrete is delivered to the bottom of the pile hole via a tremie pipe. During construction, as the concrete level rises, the tremie pipe needs to be raised in a timely manner to ensure that its bottom is always embedded at the appropriate depth in the concrete. However, this traditional construction method has the following significant problems: First, traditional grouting conduits require temporary on-site assembly, typically consisting of multiple short pipe sections connected by flanges or threads. This temporary assembly method is not only time-consuming and labor-intensive, but also makes it difficult to guarantee connection accuracy, easily leading to poor sealing at the joints and grout leakage, thus affecting the quality of concrete grouting.

[0004] Secondly, during the pouring process, as the concrete level rises, operators need to continuously lift the guide pipe and remove excess lower pipe sections as needed. This method of pouring and dismantling pipes simultaneously results in intermittent construction, making continuous pouring impossible and affecting construction efficiency.

[0005] Furthermore, traditional construction methods rely heavily on manual labor, requiring multiple workers to operate together, resulting in high labor intensity and certain safety hazards. In the construction of deep-hole cast-in-place piles, the pile hole depth often reaches tens or even hundreds of meters. Manually assembling and disassembling the pipes is not only time-consuming but also complex, and even the slightest carelessness can lead to quality accidents.

[0006] For example, Chinese invention patent CN114457786B discloses a device for controlling the grouting elevation of ultra-deep hollow concrete cast-in-place pile heads. Multiple reinforcing bars are fixedly connected in the hollow hole. The device includes a support plate slidably connected in the hollow hole, with all reinforcing bars passing through the support plate. Two markers are fixedly connected to the support plate, and pull ropes are fixedly connected to the markers. Both the markers and pull ropes are engraved with scales. A frame is provided on the ground, with rotating wheels rotatably connected to the frame. The pull ropes are wound around the corresponding rotating wheels. A driving component is provided on the frame. A grouting hole is opened in the support plate. Two guide plates are hinged to the upper surface of the support plate, communicating with the grouting hole after the two guide plates are engaged. A fan impeller is rotatably connected between the two guide plates, with the length of one blade of the fan impeller greater than the inner diameter of the end of the guide plates closest to the support plate after engagement. A vibrating plate is fixedly connected to the sidewalls of the two guide plates that are far apart from each other, with each reinforcing bar passing through the corresponding vibrating plate. This device effectively reduces construction costs.

[0007] Therefore, there is an urgent need for a deep-hole cast-in-place pile concrete grouting device that can achieve continuous grouting and a high degree of automation, in order to solve the problems of time-consuming and labor-intensive temporary pipeline assembly, discontinuous grouting process, and low construction efficiency in traditional construction methods. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention proposes a concrete grouting device for deep-hole cast-in-place piles, which solves the technical problems of time-consuming and labor-intensive temporary pipeline assembly, discontinuous grouting process, and low construction efficiency in traditional construction methods mentioned in the background.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a concrete pouring device for deep-hole cast-in-place piles, comprising: The main body is divided into upper and lower layers; A grouting component is disposed on the upper layer of the main body. The grouting component is divided into an inlet section and a flow channel section to receive the inflow of concrete. Multiple sets of pipe units are provided and can be raised and lowered on the main body. The pipe units are designed to be detachable and can be fitted onto the flow channel section when the pipe units are assembled. A lifting assembly is arranged in the lower layer of the main body and connected to the pipe unit. The lifting assembly can drive the pipe unit to rise and fall. An assembly mechanism, located in the lower layer of the main body, is capable of transporting the unassembled pipe units to the flow channel section for assembly. The drive component is installed on the upper layer of the main body and connected to the lifting component and the assembly mechanism, and can drive both of them to move simultaneously.

[0010] Furthermore, a circular groove is provided on the lower part of the main body for the pipe unit to pass through, and a first square groove for the bolt head to pass through and a second square groove for restricting the rotation of the pipe unit are provided on both sides of the circular groove.

[0011] Furthermore, the piping unit includes: The semi-cylindrical pipes are arranged in groups of two, and there are multiple groups of them. The semi-cylindrical pipes are divided into arc sections and planar sections. Two semi-cylindrical pipes can be staggered and assembled to form a cylindrical space to accommodate the flow channel section. The next group of semi-cylindrical pipes can be fixedly installed on the plane left by the staggered assembly of the previous group of semi-cylindrical pipes. Multiple threaded holes are provided and are arranged in an array along the axial direction of the semi-cylindrical pipe on the planar section; Multiple through holes are provided, arranged in an axial array along the semi-cylindrical pipe on the planar segment away from the end with the threaded hole; and At least one rack is provided and is fixedly installed on the planar section along the axial direction of the semi-cylindrical pipe. The rack can be engaged in the second square groove to restrict the rotation of the semi-cylindrical pipe.

[0012] Furthermore, the lifting assembly includes: Two first rotating shafts are symmetrically and rotatably arranged on both sides of the circular groove. A third gear is fixedly installed on a section of the first rotating shaft near the inlet section. Two screws are provided and fixedly installed at both ends of the first rotating shaft at intervals, and the interval between the two screws is less than the length of one pipe unit. The screws can be screwed to the rack.

[0013] Furthermore, the assembly mechanism includes: Two turntable gears are provided, both of which are rotatably arranged in the lower layer of the main body and located on both sides of the injection component; and There are two placement seats, both of which can be slidably arranged on the turntable gear, and both placement seats slide along the same diameter of the turntable gear.

[0014] Furthermore, the assembly mechanism also includes: A first magnetic element is fixedly arranged on the turntable gear, and the first magnetic element is capable of temporarily magnetically attracting the placement seat to the turntable gear; and A second magnetic component is fixedly arranged on the placement base, and the second magnetic component is capable of magnetically attracting the unassembled semi-cylindrical pipe to the placement base.

[0015] Furthermore, the driving component includes: A motor is mounted on the main body, and the output shaft of the motor is fixedly connected to the first rotating shaft. Two second rotating shafts are provided, each rotatably arranged on the main body. A first gear and a second gear are fixedly mounted at both ends of the second rotating shaft, with the second gear meshing with the turntable gear. A chain is disposed on the main body, and the chain meshes with the first gear and the third gear.

[0016] Furthermore, when the screw drives the pipe unit to rise or fall by one rack height, the second gear can drive the turntable gear to rotate half a revolution.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention enables continuous and uninterrupted concrete pouring for deep-hole cast-in-place piles. By setting up assemblable and automatically lifting pipe units, along with matching assembly mechanisms and lifting components, the pipes can be automatically lifted upwards during the pouring process without stopping the pouring for manual pipe disassembly. This improves construction efficiency and pouring quality. The device has a high degree of automation, is simple to control, and reduces manual labor intensity. Furthermore, by using a drive component to simultaneously drive the lifting components and assembly mechanism to work together, it achieves automatic handling of the pipe units, assists construction personnel in assembly and lifting, reduces manual operation, lowers the labor intensity of workers, and also improves construction safety.

[0018] 2. This invention features a reasonable structural design and precise, reliable transmission. The precise lifting and lowering of the pipe unit is achieved through the cooperation of a screw and rack, while the gear transmission system ensures coordinated operation between the lifting and assembly actions. This results in stable and reliable operation of the entire device, a low failure rate, and strong adaptability, making it suitable for construction of cast-in-place piles at different depths. By setting multiple sets of continuously assembleable pipe units, the pipe length can be flexibly adjusted according to the pile hole depth to meet different engineering needs, thus improving the versatility and practicality of the device.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0023] Example: like Figures 1 to 8 As shown, the present invention provides a concrete grouting device for deep-hole cast-in-place piles, including a main body 101, a grouting component 102, a pipeline unit, a lifting assembly, an assembly mechanism, and a drive assembly.

[0024] The main body 101 serves as the supporting frame for the entire device, consisting of two layers. The upper layer is used to install the drive components, while the lower layer is used to house the lifting components and assembly mechanism. The lower layer of the main body 101 has a circular groove 105 for the pipe unit to pass through (the circular groove 105 can be appropriately lengthened to extend the pipe for increased stability). On both sides of the circular groove 105 are a first square groove 106 for bolt heads to pass through and a second square groove 107 to restrict the rotation of the pipe unit, ensuring stability during the lifting and lowering of the pipe unit.

[0025] like Figures 1 to 4As shown, the grouting component 102 is disposed on the upper layer of the main body 101. The grouting component 102 is divided into an inlet section 103 and a flow channel section 104. The inlet section 103 is used to receive the inflow of concrete, and the flow channel section 104 is used to transport the concrete to the pipe unit (the length of the flow channel section 104 should be able to be inserted into the circular groove 105). The flow channel section 104 is designed as a cylindrical structure to facilitate connection with the pipe unit.

[0026] like Figure 6 , 7 As shown, the pipe unit includes a semi-cylindrical pipe 201, threaded holes 204, through holes 205, and a rack 206. The semi-cylindrical pipe 201 is divided into an arc segment 202 and a flat segment 203. Two semi-cylindrical pipes 201 form a group and can be staggered and assembled to form a cylindrical space to accommodate the flow channel segment 104. The next group of semi-cylindrical pipes 201 can be fixedly installed on the plane left by the staggered assembly of the previous group of semi-cylindrical pipes 201, realizing the continuous assembly of multiple groups of pipe units. Multiple threaded holes 204 are provided and are arranged in an array along the axial direction of the semi-cylindrical pipe 201 on the flat segment 203. Multiple through holes 205 are provided and are arranged in an array along the axial direction of the semi-cylindrical pipe 201 on the flat segment 203 away from the end of the flat segment 203. At least one rack 206 is provided and is fixedly installed along the axial direction of the semi-cylindrical pipe 201 on the flat segment 203. The rack 206 can be engaged in the second square groove 107 to restrict the rotation of the semi-cylindrical pipe 201.

[0027] like Figure 2 , 3 As shown, the lifting assembly includes a first rotating shaft 207 and screws 209. Two first rotating shafts 207 are provided, symmetrically and rotatably arranged on both sides of the circular groove 105. A third gear 208 is fixedly installed on a section of the first rotating shaft 207 near the inlet section 103. Two screws 209 are provided, fixedly installed at intervals at both ends of the first rotating shaft 207, with the interval between the two screws 209 being less than the length of a pipe unit. The screws 209 can be screwed into a rack 206, and the rotation of the screws 209 drives the pipe unit to rise and fall vertically.

[0028] like Figure 8As shown, the assembly mechanism includes a turntable gear 301, a placement seat 302, a first magnetic component 303, and a second magnetic component 304 (a handle can also be added to the placement seat 302 to facilitate the movement of workers). Two turntable gears 301 are provided, both rotatably arranged on the lower layer of the main body 101 and located on both sides of the pouring component 102 (the height difference between the turntable gears 301 is for convenient misalignment assembly of the semi-cylindrical pipe 201). Two placement seats 302 are provided, both slidably arranged on the turntable gear 301, and both placement seats 302 slide along the same diameter of the turntable gear 301. The first magnetic component 303 is fixedly arranged on the turntable gear 301, and can temporarily magnetically attract the placement seat 302 to the turntable gear 301 (to prevent the placement seat 302 from moving randomly during rotation). The second magnetic component 304 is fixedly arranged on the placement seat 302, and the second magnetic component 304 can magnetically attract the unassembled semi-cylindrical pipe 201 to the placement seat 302.

[0029] like Figure 3 As shown, the drive assembly includes a motor 305, a second rotating shaft 306, and a chain 309. The motor 305 is mounted on the main body 101, and its output shaft is fixedly connected to the first rotating shaft 207 (the output shaft of the motor 305 can also be fixedly connected to the second rotating shaft 306), providing power to the entire device. Two second rotating shafts 306 are provided, both rotatably mounted on the main body 101. A first gear 307 and a second gear 308 are fixedly mounted at both ends of the second rotating shaft 306, with the second gear 308 meshing with the turntable gear 301. The chain 309 is mounted on the main body 101, meshing with the first gear 307 and the third gear 208, transmitting the power from the motor 305 to the lifting assembly and the assembly mechanism.

[0030] The working principle and usage process of this invention are as follows: First, before pouring concrete, the operator places two semi-cylindrical pipes 201 on two placement seats 302 respectively, and temporarily fixes the semi-cylindrical pipes 201 on the placement seats 302 by the second magnetic component 304. The motor 305 is started, and the motor 305 drives the screw 209 to rotate through the first rotating shaft 207, and at the same time drives the second rotating shaft 306 to rotate through the chain 309.

[0031] In the initial assembly stage, the motor 305 is started, and the turntable gear 301 rotates 180 degrees, rotating the placement seat 302 from the outside to the inside of the main body 101, so that the semi-cylindrical pipe 201 is located on the outer surface of the flow channel section 104. The placement seat 302 is pushed, causing the semi-cylindrical pipe 201 to move to the surface of the flow channel section 104 and fit. After the construction personnel fix the two semi-cylindrical pipes 201 together with bolts, the assembly of the first set of pipe units is completed. The motor 305 continues to work, the lifting component starts to work, the screw 209 rotates to drive the rack 206 to descend, and drives the semi-cylindrical pipe 201 to move downward. This process is repeated until a pipe of the appropriate length is assembled.

[0032] As concrete pouring continues and the concrete level rises within the pile hole, the pipe unit needs to be lifted upwards in conjunction with the concrete level monitoring equipment. At this point, motor 305 rotates in the opposite direction, screw 209 drives the assembled pipe unit upwards, and simultaneously second gear 308 drives turntable gear 301 to rotate half a revolution, disassembling the semi-cylindrical pipe 201 and placing it on the placement seat 302 (concrete level monitoring is existing technology and will not be elaborated here).

[0033] This cycle is repeated, enabling continuous concrete pouring and automatic lifting and manual disassembly of the pipeline without stopping the pouring process, thus improving construction efficiency. After pouring is completed, each pipeline unit is cleaned and recycled for future use.

[0034] The beneficial effects of this invention are mainly reflected in the following aspects: First, it realizes continuous concrete pouring, avoiding construction interruptions caused by pipe dismantling in traditional construction methods, and significantly improving construction efficiency; second, it has a high degree of automation, greatly reducing manual labor intensity and operational risks; third, it has high pipe assembly precision and good sealing performance, effectively avoiding grout leakage problems; fourth, it has a reasonable structural design and precise and reliable transmission, ensuring stable operation of the device; and fifth, it has strong adaptability, and the pipe length can be flexibly adjusted according to different pile hole depths to meet various engineering needs.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to the present invention, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
