Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, and more specifically, to a concrete pouring device for building pile foundation construction. Background Art

[0002] Pile foundation for housing construction is a deep foundation commonly used in construction projects. It is mainly composed of piles and pile caps (referred to as caps) connected to the tops of the piles. The pile foundation connects the tops of several piles into a whole through the caps to jointly bear dynamic and static loads. During the construction of pile foundation for housing construction, pouring concrete after the pile hole is formed and the steel cage is placed is the key link in the formation of the pile foundation.

[0003] The conduit pouring method is one of the most commonly used methods for pouring pile foundations for building construction. The pouring process generally includes: preliminary preparation, conduit installation, concrete mixing and transportation, pouring and post-processing. After the pile hole is drilled, the steel cage is hoisted into the pile hole. Then, when installing the conduit, a crane is used to connect the conduit section by section using threads and other methods and hoist it into the pile hole. Then, the concrete is introduced into the pile hole through the funnel at the top of the conduit for pouring. As the concrete is poured, the conduit is gradually lifted and the pouring is finally completed. However, this pouring method still has certain defects: First, during the pouring process, the funnel is hoisted and installed by a crane or fixed lifting equipment, and the conduit is gradually lifted during the pouring process, but the conduit is not guided and limited. Even if there is no special limit on the conduit, the conduit can be poured in a stable state to a certain extent due to the friction generated by the viscosity and cohesion of the concrete on the conduit due to its own gravity and the lifting process after the conduit is inserted into the concrete. However, when affected by wind, the wind will generate lateral force on the connection between the lifting equipment and the conduit, causing the conduit to shift or shake, thereby causing the bottom end of the conduit to deviate, thereby affecting the uniform distribution of concrete. Therefore, pouring operations are generally suspended in windy weather. In addition, when the pouring process is caused by vibration due to the movement of equipment and vehicles on the construction site, the conduit may collide or rub against the steel cage, causing the steel cage or conduit to deform, or even break.

[0004] Secondly, there is a lack of centering and fixing of the steel cage during the pouring process. Although the pile hole is surface treated before placing the steel cage and the bottom is relatively flat after treatment, the concrete flows into the pile hole from the bottom of the conduit during pouring. The impact force generated by the flow may produce lateral pressure on the steel cage, causing the steel cage to shift. The shift of the steel cage will cause uneven distribution of concrete when wrapping the steel cage, which will in turn cause uneven force on the pile foundation, affecting the overall bearing capacity and stability of the pile foundation. In the long-term use process, this uneven force may cause settlement, tilt and other problems of the pile foundation. Summary of the invention

[0005] The present invention provides a concrete pouring device for building foundation pile construction, which solves the technical problems of the lack of limit for the conduit and the centering treatment of the steel reinforcement cage in the prior art.

[0006] The present invention provides a concrete pouring device for building foundation pile construction, including a funnel and a conduit fixedly installed at the bottom of the funnel and inserted into the pile hole and perpendicular to the bottom of the pile hole. An installation frame is slidably installed on the outer side of the conduit. A positioning and stabilizing unit and an integrated centering unit are arranged at the bottom of the installation frame. The positioning and stabilizing unit includes a plurality of positioning components distributed circumferentially and a control component for controlling the fixation of the positioning components to the pile head. The integrated centering unit includes a plurality of centering components distributed circumferentially and a driving component for driving the centering components to perform centering clamping on the steel reinforcement cage.

[0007] The centering component includes an L-shaped plate, a fixed column fixedly installed on the side of the L-shaped plate close to the conduit, and a fixed cylinder fixedly installed at the end of the fixed column away from the L-shaped plate. A spring telescopic rod is also slidably connected to the end of the fixed column away from the L-shaped plate and located inside the fixed cylinder. A guiding groove is formed on the fixed cylinder. A sliding rod slidably connected to the guiding groove is fixedly installed on the outer side of the fixed section of the spring telescopic rod. A centering plate is fixedly installed on the telescopic section of the spring telescopic rod.

[0008] The control component controls the positioning components to be fixed to the pile head to fix and position the installation frame, thereby fixing and positioning the conduit. At the same time, the sliding rod of the driving component slides towards the side close to the steel reinforcement cage in the guiding groove and drives the spring telescopic rod to push the centering plate to clamp the steel reinforcement cage, so that the steel reinforcement cage is centered and concentric with the pile hole and the conduit.

[0009] Further, the positioning and stabilizing unit further includes a dividing ring fixedly installed at the bottom of the installation frame and concentric with the conduit. The positioning component includes a control groove formed on the dividing ring and a C-shaped rod slidably connected in the control groove. A positioning plate cooperating with the pile head is fixedly installed at the bottom end of the C-shaped rod.

[0010] Further, a limiting rod is fixedly installed on the side of the positioning plate away from the conduit. A support ring cooperating with the ground is slidably connected to the outside of a plurality of limiting rods. The L-shaped plate is fixedly installed on the outside of the dividing ring.

[0011] Further, the control component includes a control ring rotatably installed at the bottom of the dividing ring. Arc-shaped grooves are uniformly formed on the bottom of the control ring along its circumference. A control rod slidably connected to the arc-shaped groove is fixedly installed at the bottom of the horizontal section above the C-shaped rod.

[0012] Further, a fixing plate is fixedly installed on the outside of the dividing ring. A driving gear is rotatably installed at the bottom of the fixing plate. A plurality of teeth meshing with the driving gear are formed on the outside of the control ring. The driving gear is connected to an external driving source.

[0013] Furthermore, the driving assembly includes a rotating cylinder rotatably mounted on one end of the fixed column away from the L-shaped plate and located outside the fixed cylinder, and a spiral groove opened on the rotating cylinder and slidably connected to the sliding rod.

[0014] Furthermore, a bevel gear is provided on the fixed sleeve outside the rotating cylinder, and a bevel gear ring meshing with the bevel gear is fixedly installed on the bottom of the control ring through a plurality of mounting rods.

[0015] Furthermore, a reinforcing guide sleeve is fixedly mounted on the bottom of the mounting frame and is slidably mounted on the outside of the catheter, and the reinforcing guide sleeve is used to reinforce the positioning of the catheter.

[0016] Furthermore, a plurality of U-shaped rods distributed in a circumference are fixedly installed at the bottom of the conduit, and a conical block is commonly installed at one end of the plurality of U-shaped rods located inside the conduit, and the conical block plays a diversion role for concrete during pouring.

[0017] Furthermore, a plurality of lifting rings distributed in a circumference are fixedly installed on the outside of the funnel, and the lifting rings are connected to external lifting equipment during pouring.

[0018] The beneficial effects of the present invention are: 1. The steel cage is clamped and centered by the centering component so that it can be located in the middle of the pile foundation during and after pouring, thereby helping to improve the overall strength and stability of the pile foundation structure after pouring, and can give full play to the tensile effect of the steel cage, share the external load with concrete, and improve the bearing capacity of the pile foundation. At the same time, the centers of the steel cage, pile hole and conduit coincide with each other. When the centers of the steel cage, pile hole and conduit completely coincide with each other, the problem of uneven concrete pouring caused by center position deviation can be minimized.

[0019] 2. During the pouring and lifting process, the conduit always slides along the reinforced guide sleeve and the mounting frame. Under the guidance and limiting effect of the reinforced guide sleeve and the mounting frame, the conduit can always maintain a vertical upward lifting, avoiding the uneven distribution of concrete flow, which leads to a large lateral pressure during the pouring process, causing a certain amount of squeezing on the pile hole wall, resulting in deformation or collapse of the pile hole wall, and then the verticality of the pile hole cannot be guaranteed, increasing the risk of tilting or bending of the pile body.

[0020] 3. During the pouring process, as the concrete is poured, the funnel and the conduit are gradually and slowly lifted upwards through external lifting equipment. This can avoid the problem of too fast pouring speed causing the concrete to generate a large impact force in the pile hole, thereby increasing the risk of pile bending. At the same time, during the pouring process, ensure that the lower end of the conduit is always buried in the concrete at a depth of 0.8m to 1.5m to prevent the pile from breaking due to the conduit being raised from the concrete surface, thereby ensuring the continuity and integrity of the pile body.

[0021] 4. Synchronously clamping the pile head through several positioning plates ensures the stability of the mounting frame, thereby ensuring the centering effect of the steel reinforcement cage and the stability of the conduit limit, and avoiding the pouring quality problems caused by position deviation.

[0031] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is to enable those skilled in the art to better understand and implement the subject matter described herein. The functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, a concrete pouring device for pile foundation construction of building construction is proposed, which is used for pouring concrete in a pile hole on the ground. Before pouring concrete, a steel cage is placed in the pile hole, and a pile head protruding from the ground surface is provided at the top of the pile hole. The concrete pouring device for pile foundation construction of building construction includes: a funnel 1 and a conduit 2 fixedly installed at the bottom of the funnel 1 and inserted into the pile hole and perpendicular to the bottom of the pile hole. A mounting frame 3 is slidably installed on the outer side of the conduit 2. A positioning and stabilizing unit 4 and an integrated centering unit 5 are provided at the bottom of the mounting frame 3. The positioning and stabilizing unit 4 includes a plurality of positioning components 401 distributed circumferentially and a control component 402 for controlling the positioning component 401 to be fixed to the pile head. The integrated centering unit 5 includes a plurality of centering components 501 distributed circumferentially and a driving component 502 for driving the centering component 501 to center and clamp the steel cage.

[0033] See also Figure 1 and Figure 2 A plurality of lifting rings 7 distributed in a circumference are fixedly installed on the outside of the funnel 1, and the lifting rings 7 are connected to the external lifting equipment during pouring.

[0034] See also Figure 2 , Figure 3 and Figure 4 A reinforcing guide sleeve 6 is fixedly installed at the bottom of the mounting frame 3 and is slidably mounted on the outside of the catheter 2. The reinforcing guide sleeve 6 strengthens the positioning of the catheter 2. A limiting ring is provided at the bottom of the catheter 2 to limit the mounting frame 3 to prevent the mounting frame 3 from falling off the catheter 2.

[0035] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 A plurality of U-shaped rods 8 distributed in a circumference are fixedly installed at the bottom of the conduit 2. A conical block 9 is installed at one end of the plurality of U-shaped rods 8 located inside the conduit 2. The conical block 9 plays a diversion role for the concrete during pouring.

[0036] When in use, first connect the lifting ring 7 to the external lifting equipment, lift the funnel 1 and the conduit 2 to the top of the pile hole through the external lifting equipment, and then gradually lower the funnel 1 and the conduit 2. During this process, the positioning component 401 first contacts the ground, and then the control component 402 controls the positioning component 401 to be fixed to the pile head to position the mounting frame 3, thereby limiting the conduit 2. At this time, the conduit 2 is located in the center of the pile hole and maintains a vertical state. At the same time, during the positioning process of the mounting frame 3, the driving component 502 will also be synchronously driven to drive the centering component 501 to clamp and center the steel cage to ensure that the center of the steel cage coincides with the center of the pile hole, thereby ensuring that the structural force is evenly distributed inside the pile body, thereby improving the bearing capacity and stability of the subsequent pile foundation. To prevent the position deviation of the steel cage, which may lead to stress concentration inside the pile body and increase the risk of pile body damage, the funnel 1 and the conduit 2 continue to move downward until the bottom end of the conduit 2 is 8-12 cm away from the bottom of the pile hole (an ultrasonic rangefinder is installed on the conduit 2 to monitor the distance between the bottom end of the conduit 2 and the bottom of the pile hole in real time), so that the air and excess moisture in the conduit 2 can be smoothly discharged at the initial stage of pouring. Then, the externally mixed concrete is introduced into the conduit 2 through the funnel 1 and poured into the pile hole after being diverted by the conical block 9. The concrete diverted by the conical block 9 can be evenly distributed and discharged, thereby avoiding the generation of vortexes and bubbles in the concrete without diversion during the flow process, thereby improving the pouring quality of the concrete.

[0037] During the pouring process, as the concrete is poured, the funnel 1 and the conduit 2 are gradually and slowly lifted upwards by external lifting equipment to avoid excessive pouring speed, which may cause the concrete to generate a large impact force in the pile hole, thereby increasing the risk of pile bending. At the same time, during the pouring process, ensure that the lower end of the conduit 2 is always buried in the concrete at a depth of 0.8m to 1.5m (scale marks are set at 0.8m and 1.5m on the conduit 2, and the two marks are distinguished by different colors. At the same time, a CCD camera is installed on the conduit 2 to monitor the scale marks in real time to ensure that the buried depth of the conduit 2 meets the requirements) , preventing the pile from breaking due to the guide tube 2 being lifted out of the concrete surface, ensuring the continuity and integrity of the pile body, and in the lifting process, the guide tube 2 always slides along the reinforced guide sleeve 6 and the mounting frame 3. Under the guidance and limiting action of the reinforced guide sleeve 6 and the mounting frame 3, the guide tube 2 can always maintain a vertical upward lift, avoiding the problem that the uneven distribution of concrete flow discharge leads to a large lateral pressure during the pouring process, causing a certain amount of squeezing on the pile hole wall, thereby causing the pile hole wall to deform or collapse, and then the verticality of the pile hole cannot be guaranteed, increasing the risk of inclination or bending of the pile body.

[0038] See also Figure 3 , Figure 4 , Figure 5 and Figure 7, the positioning and stabilizing unit 4 further includes a indexing ring 403 fixedly installed at the bottom of the mounting frame 3 and concentric with the conduit 2. The positioning assembly 401 includes a control groove 4012 formed in the indexing ring 403 and a U-shaped rod 4013 slidably connected in the control groove 4012. A positioning plate 4014 adapted to cooperate with the pile head is fixedly installed at the bottom end of the U-shaped rod 4013. A limiting rod 4011 is fixedly installed on one side of the positioning plate 4014 away from the conduit 2. A support ring 404 adapted to cooperate with the ground is slidably connected to the outside of a plurality of limiting rods 4011. During the working process, the support ring 404 abuts against the ground, and the rotation of the support ring 404 is restricted by the frictional force between the support ring 404 and the ground.

[0039] Refer to Figure 3 , Figure 4 , Figure 5 and Figure 7 , the control assembly 402 includes a control ring 4021 rotatably installed at the bottom of the indexing ring 403. Arc-shaped grooves 4022 are uniformly formed at the bottom of the control ring 4021 along its circumference. A control rod 4023 slidably connected to the arc-shaped grooves 4022 is fixedly installed at the bottom of the horizontal section above the U-shaped rod 4013.

[0040] Refer to Figure 4 , Figure 5 and Figure 7 , a fixing plate 4024 is fixedly installed on the outside of the indexing ring 403. A driving gear 4025 is rotatably installed at the bottom of the fixing plate 4024. A plurality of teeth 4026 meshing with the driving gear 4025 are formed on the outside of the control ring 4021. The driving gear 4025 is connected to an external driving source.

[0041] During specific use, the rotation of the driving gear 4025 is controlled by an external driving source. The control ring 4021 is driven to rotate by the meshing of the driving gear 4025 and the teeth 4026. Thus, the control rod 4023 is toggled by the arc-shaped grooves 4022, driving the control rod 4023 to push the U-shaped rod 4013 to slide along the control groove 4012 towards the side close to the pile head. Furthermore, the positioning plate 4014 is driven to slide towards the side close to the pile head and finally contact the pile head, enabling a plurality of positioning plates 4014 to synchronously clamp the pile head, fixedly positioning the mounting frame 3. During this process, the limiting rods 4011 slide radially along the support ring 404, playing a limiting role on the positioning plate 4014 to prevent the positioning plate 4014 from deflecting during movement. Thereby, the limiting of the conduit 2 is realized, enabling the conduit 2 to be located at the center of the pile hole and maintain a vertical state. During this process, the driving assembly 502 is also synchronously driven to drive the centering assembly 501 to clamp and center the steel reinforcement cage. Thus, the stability of the mounting frame 3 is ensured by the synchronous clamping of the pile head by a plurality of positioning plates 4014, and the centering state of the steel reinforcement cage and the stability of the conduit 2 are ensured, avoiding the pouring quality problems caused by position deviation.

[0042] After the pouring is completed, an external drive source is used to control the driving gear 4025 to engage with the teeth 4026, driving the control ring 4021 to rotate. Thereby, the control rod 4023 is toggled through the arc-shaped groove 4022, driving the control rod 4023 to push the C-shaped rod 4013 to slide along the control groove 4012 away from the pile head side, and further driving the positioning plate 4014 to slide away from the pile head side and disengage from the pile head, releasing the clamping of the pile head, and thus releasing the fixed positioning of the mounting bracket 3. During this process, the driving component 502 is also synchronously driven to drive the centering component 501 to disengage from the steel reinforcement cage, so as to pour the next pile hole.

[0043] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in FIGS.

[0044] Refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown in FIGS.

[0045] Refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown in FIGS.

[0046] During specific use, during the rotation of the control ring 4021, the bevel gear ring 504 will be synchronously driven to rotate through a number of mounting rods 503, and the bevel gear ring 504 will mesh with the bevel gear 5022, thereby driving the rotating cylinder 5021 to rotate, so that the spiral groove 5023 drives the sliding rod 5014 to slide in the guide groove 5017 toward the side close to the steel cage, and then drives the centering plate 5016 to slide toward the side close to the steel cage, so that the centering plates 5016 synchronously clamp and center the steel cage to ensure that it can be located in the middle of the pile foundation after pouring, thereby helping to improve the overall strength and stability of the pile foundation structure after pouring, and can give full play to the tensile effect of the steel cage, share the external load with the concrete, and improve the bearing capacity of the pile foundation. At the same time, the centers of the steel cage, pile hole and conduit 2 coincide with each other. When the centers of the steel cage, pile hole and conduit 2 completely coincide with each other, the problem of uneven concrete pouring caused by center position deviation can be minimized.

[0047] When pouring is completed, during the rotation of the control ring 4021, the bevel gear ring 504 will be synchronously driven to rotate through a number of mounting rods 503, so that the bevel gear ring 504 is meshed with the bevel gear 5022, thereby driving the rotating cylinder 5021 to rotate, so that the spiral groove 5023 drives the sliding rod 5014 to slide in the guide groove 5017 away from the steel cage, thereby driving the centering plate 5016 to slide away from the steel cage, so that the centering plates 5016 synchronously release the clamping and centering of the steel cage, so as to cast the next pile hole.

[0048] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
