Description

Technical Field

[0001] This application relates to the field of construction equipment technology, and in particular to a concrete pouring device. Background Technology

[0002] In the construction of cast-in-place piles, the tremie method is commonly used for concrete pouring. During construction, a pile hole needs to be drilled, and the hole wall is lined with protective mud. A tremie pipe is placed inside the pile hole, and concrete is pumped into the tremie pipe. The tremie pipe then carries the concrete to the bottom of the pile hole, gradually replacing the mud in the hole from bottom to top until a complete cast-in-place pile is formed.

[0003] In the muddy environment of the pile hole, quality defects such as air bubbles, mud inclusions, or segregation are prone to occur during concrete pouring, resulting in insufficient strength and durability of the cast-in-place pile. Therefore, manual vibration of the concrete is required after pouring, which not only increases the construction period, but also makes it difficult to operate conventional vibrators in the narrow and enclosed tremie pipe, often resulting in insufficient vibration of the concrete, leading to low efficiency and poor processing effect. Utility Model Content

[0004] Therefore, it is necessary to provide a concrete pouring device to address the problems of low efficiency and poor pouring effect in the processing of cast-in-place piles.

[0005] This utility model provides a concrete pouring device for pouring cast-in-place piles in pile holes. The concrete pouring device includes: a pumping mechanism for conveying concrete; a guide pipe for being movably disposed in the pile hole, the guide pipe having a first conveying channel, the two ends of the first conveying channel being respectively connected to a first input port and a first output port, the first output port being placed at one end of the bottom of the pile hole, and the first input port being correspondingly disposed to the output end of the pumping mechanism; and a vibration mechanism installed on the guide pipe.

[0006] In one embodiment, the vibrating mechanism includes a drive unit and an eccentric block. The drive unit is mounted on the guide tube, and the power output end of the drive unit is eccentrically mounted to the eccentric block. The rotation axis of the eccentric block is perpendicular to the extension direction of the guide tube.

[0007] In one embodiment, the drive unit is provided with a power cord for connecting to a power source, and the conduit includes a wire protector installed on the outer side wall of the conduit. The wire protector has a wire-passing channel along the axial direction, and the power cord passes through the wire-passing channel.

[0008] In one embodiment, the vibration mechanism further includes a vibrating plate mounted on the outer wall of the conduit, and the drive unit and the eccentric block are both mounted on the vibrating plate.

[0009] In one embodiment, the vibrating plate is connected to the conduit by a first fastener, and the vibrating plate is disposed at one end of the conduit near the bottom of the hole.

[0010] In one embodiment, the pumping mechanism includes a concrete pump truck and a conveying pipeline. The conveying pipeline is provided with a second conveying channel. The two ends of the second conveying channel are respectively connected to a second input port and a second output port. The second input port is connected to the output end of the concrete pump truck, and the second output port is correspondingly provided to the first input port.

[0011] In one embodiment, the conduit has a funnel structure at one end of the first inlet.

[0012] In one embodiment, the concrete pouring device further includes an acceleration sensor mounted on the conduit.

[0013] In one embodiment, the conduit includes a plurality of sub-conduits, which are detachably connected along an axial direction.

[0014] In one embodiment, the connecting end of the sub-conduit is provided with a connecting flange, and the connecting flanges between two adjacent sub-conduits are connected by a second fastener.

[0015] The aforementioned concrete pouring device has a tremie pipe installed inside the pile hole. Concrete is pumped in through the first inlet of the tremie pipe and then delivered to the bottom of the pile hole through the first outlet. Concrete is poured from top to bottom within the pile hole to form a cast-in-place pile. Furthermore, a vibration mechanism is installed on the tremie pipe. This mechanism simultaneously drives the tremie pipe to vibrate the concrete during pouring, ensuring uniform and continuous vibration as the concrete reaches the bottom of the hole. This eliminates air bubbles and mud inclusions in real time, significantly improving the density and strength of the concrete, reducing segregation and mud inclusions. The simultaneous pouring and vibration reduce the need for separate vibration steps, shortening the construction period. This device offers advantages such as high efficiency and excellent pouring results. Attached Figure Description

[0027] See Figure 1 and Figure 2 The diagram shows a structural schematic of a concrete pouring device according to an embodiment of the present application. The concrete pouring device is used to pour cast-in-place piles in pile holes 10. The pile hole 10 is provided with wall-protecting mud, which can prevent the hole from collapsing and maintain the stability of the pile hole 10.

[0028] The concrete pouring device includes a pumping mechanism 100, a conduit 200, and a vibrating mechanism 300. The pumping mechanism 100 is used to transport concrete.

[0029] The guide pipe 200 is movably installed in the pile hole 10. The guide pipe 200 has a first conveying channel 201, and its two ends are respectively connected to a first input port 202 and a first output port 203. The first input port 202 is located outside the opening 11 of the pile hole 10, and the first output port 203 is placed at one end of the bottom 12 of the pile hole 10. The first input port 202 is correspondingly set to the output end of the pumping mechanism 100. The vibrating mechanism 300 is installed on the guide pipe 200.

[0030] The concrete pouring device described in this application embodiment has a conduit 200 installed inside the pile hole 10. Concrete is fed into the conduit 200 through its first inlet 202 via a pumping mechanism 100, and then transported to the bottom 12 of the pile hole 10 through its first outlet 203, allowing the concrete to be poured from top to bottom within the pile hole 10 to form a cast-in-place pile. Furthermore, a vibration mechanism 300 is installed on the conduit 200, which can simultaneously drive the conduit 200 to vibrate during concrete pouring.

[0031] The concrete pouring device described in this application embodiment uses a vibration mechanism 300 installed in the guide pipe 200. This allows for uniform and continuous vibration of the concrete as it is being delivered to the bottom of the hole 12, eliminating air bubbles and mud inclusions in real time, significantly improving the density and strength of the concrete, reducing segregation and mud inclusion, and reducing the need for separate vibration steps by performing pouring and vibration simultaneously, thus shortening the construction period. It offers advantages such as high efficiency and good pouring results.

[0032] Furthermore, this application is applicable to the construction of medium-section cast-in-place piles and can be extended to various pile foundation projects such as bridges, roads, tunnels and high-rise buildings. It has the advantages of simple structure, convenient maintenance, high reusability, and good economic benefits.

[0033] Combination Figure 4 The diagram shows a structural schematic of the vibration mechanism 300 of a concrete pouring device according to one embodiment of this application. In some embodiments, the vibration mechanism 300 includes a drive unit 310 and an eccentric block 320. The drive unit 310 is mounted on the guide pipe 200, and the power output end of the drive unit 310 is eccentrically mounted to the eccentric block 320. The rotation axis of the eccentric block 320 is perpendicular to the extension direction of the guide pipe 200, so that the guide pipe 200 is vibrated along the extension direction of the guide pipe 200 under the drive of the eccentric block 320. Specifically, the eccentric block 320 is a disc structure.

[0034] The structural design of this embodiment is simple and compact. The drive unit 310 is directly installed on the outer wall of the guide pipe 200, and the eccentric connection between the drive unit 310 and the eccentric block 320 can efficiently convert the power of the drive unit 310 into the vibration energy of the eccentric block 320, which is then directly transmitted to the concrete through the guide pipe 200, reducing energy loss and achieving precise vibration. At the same time, the synchronous vibration of the eccentric block 320 during the pouring process can effectively remove air bubbles inside the concrete, enhance the coating force of the grout on the aggregate, thereby reducing the risk of concrete segregation, improving the density and integrity of the pile body, and taking into account the convenience of construction, vibration efficiency and project quality.

[0035] In one exemplary embodiment, the drive unit 310 is a drive motor. During pouring, the speed of the drive motor can be adjusted through the ground frequency converter control cabinet to achieve a continuously adjustable vibration frequency of 25~50Hz, which has the advantage of strong adaptability.

[0036] In an optional embodiment, such as Figures 2 to 4 As shown, the drive unit 310 is provided with a power cord 311 for connecting to a power source. The conduit 200 includes a wire protector 210, which is installed on the outer side wall of the conduit 200. The wire protector 210 is provided with a wire passage 211 along the axial direction, and the power cord 311 passes through the wire passage 211.

[0037] The drive unit 310 requires a power cable 311 to be installed inside the pile hole 10, which is not only cumbersome to operate, but also makes the power cable 311 susceptible to compression or damage from the reinforcing cage, posing a significant risk. This embodiment addresses this by installing a cable guard 210 on the outer wall of the conduit 200, which provides precise fixation and full-length protection for the power cable 311 of the drive unit 310. On one hand, the cable passage 211 of the cable guard 210 can orderly constrain the power cable 311, preventing it from becoming tangled and affecting the lifting of the conduit 200 during construction. On the other hand, the cable guard 210 can isolate the power cable 311 from direct scouring and erosion by concrete or prevent compression and scraping between the power cable 311 and the reinforcing cage, thereby reducing the risk of insulation damage or short circuits in the power cable 311, ensuring stable power supply to the drive unit 310, and guaranteeing the reliability of the vibrating mechanism 300's continuous operation.

[0038] In an optional embodiment, such as Figure 4 As shown, the vibration mechanism 300 also includes a vibrating plate 330, which is installed on the outer side wall of the guide tube 200. The drive unit 310 and the eccentric block 320 are both installed on the vibrating plate 330.

[0039] In this embodiment, the vibrating plate 330 serves as the mounting carrier for the drive unit 310 and the eccentric block 320. It not only enables centralized assembly and synchronous fixing of the two, simplifying the installation and debugging process and reducing the difficulty of later maintenance, but also increases the contact area with the outer wall of the guide pipe 200 through the vibrating plate 330. This allows the vibration energy generated by the eccentric block 320 to be evenly transmitted to the entire guide pipe 200, avoiding excessive concentration of local vibration energy that could damage the guide pipe 200. At the same time, it allows the vibration to act more stably on the underwater concrete, improving the uniformity of vibration, increasing the density of the concrete, reducing pile defects, and ensuring the construction quality of the cast-in-place pile.

[0040] In an optional embodiment, such as Figure 4 As shown, the vibrating plate 330 is connected to the guide tube 200 via a first fastener 331, and the vibrating plate 330 is positioned at the end of the guide tube 200 near the bottom of the hole 12. In this embodiment, connecting the vibrating plate 330 to the end of the guide tube 200 near the bottom of the hole 12 via the first fastener 331 facilitates the action of the vibrating plate 330 on the freshly poured concrete and sediment concentration area at the bottom of the hole 12. This allows for more efficient removal of air bubbles from the concrete at the bottom of the hole, promotes mixing of sediment and concrete, significantly improves the density of the concrete at the bottom of the hole, and reduces defects at the bottom of the pile body caused by poor quality concrete at the bottom of the hole. Simultaneously, the connection method of the first fastener 331 facilitates the disassembly, assembly, and position adjustment of the vibrating plate 330, ensuring that the vibrating plate 330 remains stable and does not loosen during high-frequency vibration and the lifting of the guide tube 200, thus enhancing the working reliability of the vibration mechanism 300.

[0041] In one exemplary embodiment, the first fastener 331 is a bolt or screw.

[0042] In an optional embodiment, such as Figure 1 As shown, the pumping mechanism 100 includes a concrete pump truck 110 and a conveying pipeline 120. The conveying pipeline 120 is provided with a second conveying channel 121. The two ends of the second conveying channel 121 are respectively connected to a second input port 122 and a second output port 123. The second input port 122 is connected to the output end of the concrete pump truck 110, and the second output port 123 is correspondingly set to the first input port 202.

[0043] In this embodiment, the pumping mechanism 100 works in conjunction with the concrete pump truck 110 and the conveying pipeline 120. By using the second output port 123 of the conveying pipeline 120 and the first input port 202 of the conduit 200 to correspond to each other, the concrete can be accurately connected and smoothly conveyed from the concrete pump truck 110 to the conduit 200. This effectively avoids problems such as leakage, segregation or mixing with mud during the transfer of concrete, ensuring the continuity and stability of concrete delivery and improving construction efficiency.

[0044] In an optional embodiment, such as Figure 1As shown, the conduit 200 has a funnel structure 220 at one end of the first inlet 202. In this embodiment, by setting the funnel structure 220 at the first inlet 202 of the conduit 200, the funnel structure 220, with its wider top and narrower bottom shape, expands the concrete receiving area, allowing for more convenient and precise connection with the conveying pipe 120, reducing spillage and waste during concrete delivery. Furthermore, the funnel structure 220 is simple to manufacture and can be integrated with the conduit 200 or designed as a detachable unit, without increasing construction burden, ensuring the continuity of pouring and the quality of the concrete.

[0045] In an optional embodiment, the concrete pouring device further includes an acceleration sensor installed on the guide pipe 200. This embodiment uses the acceleration sensor to collect vibration parameters of the guide pipe 200 in real time during the vibration and pouring process, such as frequency, amplitude, and acceleration. This data allows for accurate assessment of the working status of the vibration mechanism 300, timely detection of problems such as insufficient vibration, over-vibration, or mechanism malfunction, and avoidance of defects such as uneven concrete density and segregation caused by abnormal vibration, thereby improving the quality of concrete pouring and the reliability of cast-in-place pile construction.

[0046] In an optional embodiment, the catheter 200 includes a plurality of sub-catheters, which are detachably connected along the axial direction.

[0047] In this embodiment, the conduit 200 is configured as a detachable mechanism, which can flexibly combine the number of sub-conduits according to different pile lengths of the cast-in-place pile, eliminating the need to customize the entire conduit 200 and greatly improving the equipment's versatility.

[0048] Specifically, during construction, sub-conduit pipes can be installed or disassembled section by section as the concrete pouring progresses, avoiding the inconvenience and risks of hoisting a single long conduit pipe. This is particularly suitable for deep pile construction, simplifying the operation process and improving construction efficiency. Furthermore, if a single sub-conduit pipe is damaged, only the damaged part needs to be replaced, eliminating the need for complete scrapping and reducing equipment maintenance and replacement costs. In addition, the disassembled sub-conduit pipes are smaller and lighter, facilitating transportation and storage, and can be integrated with the segmented installation of components such as the vibratory compaction mechanism 300 and the line protection device 210, further enhancing the overall flexibility and convenience of the construction process.

[0049] In an optional embodiment, the connecting end of the sub-conduit is provided with a connecting flange, and the connecting flanges between two adjacent sub-conduits are connected by a second fastener.

[0050] In this embodiment, the connection end of the sub-conduit increases the contact area of ​​the connecting flanges of adjacent sub-conduits through the connecting flange. Combined with the fastening effect of the second fastener, the sealing performance and structural strength of the connection can be significantly improved, effectively preventing mud seepage or concrete leakage during underwater pouring. At the same time, the connection method between the connecting flange and the second fastener is convenient to assemble and disassemble, and the connection is stable.

[0051] In an optional embodiment, the second fastener is a bolt or screw.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
