Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring in pipe roofs, in particular to equipment for pouring concrete in pipe roofs. Background Art

[0002] The pipe curtain method is an underground tunnel construction method suitable for the construction of large-section underground buildings. This method uses micro-pipe jacking technology to push steel pipes or pipes made of other materials around the proposed underground building to form horizontally laid steel pipe piles. These steel pipe piles are connected by locks and injected with waterproof materials to form an impermeable underground space for the construction of underground buildings.

[0003] During the pipe-curtain construction process, pouring concrete into the steel pipe is a key step. However, since steel pipes are relatively slender compared to tunnels, problems such as uneven filling and difficulty in removing bubbles may occur during concrete pouring, resulting in poor concrete quality and ultimately affecting the bearing performance and stability of the steel pipe.

[0004] After searching, the Chinese utility model patent with publication number CN217421212U discloses a construction device for pouring concrete in a long-distance, small-diameter pipe curtain, which includes a steel pipe used for surrounding support, with one end of the steel pipe blocked and the other end provided with an opening; a movable baffle, which is arranged in the steel pipe and fits the inner wall of the steel pipe; a feed pipe, which is arranged on the movable baffle and is connected to the pouring concrete; an exhaust hole, which is provided on the movable baffle and is used for exhausting gas during concrete pouring; under the action of external force, the movable baffle moves toward the open end of the steel pipe, thereby driving the feed pipe to pour concrete. This application uses the provision of a blocking plate and a movable baffle to perform movable, extended-type concrete pouring in the steel pipe, thereby avoiding the accumulation of concrete and the formation of a vacuum zone. However, during the concrete pouring process, continuous vibration operations are often required to ensure its density and strength. However, this device can only ensure that the concrete will be fully filled into the interior of the steel pipe, but cannot guarantee the density and uniformity of the concrete after pouring. Therefore, it is difficult to ensure the safety and stability of the concrete structure. Utility Model Content

[0008] Further, the material bucket is cylindrical, and first through holes are opened in the middle of both sides of the material bucket. The connecting shaft penetrates the material bucket at the two first through holes, and the connecting shaft is rotatably connected to the material bucket at the circular through holes. One side of the material bucket is fixedly connected with a casing outside one end of the connecting shaft, and a motor is fixedly connected to the inner wall of one side of the casing. The motor is fixedly connected to the connecting shaft.

[0009] Further, a second through hole is opened on one side of the transmission cylinder away from the casing. The rotating shaft is rotatably connected to the transmission cylinder at the second through hole. The driving mechanism includes a driving wheel and a driven wheel. The driving wheel and the driven wheel are respectively key-connected to one end of the connecting shaft and the rotating shaft, and the same belt is sleeved outside the driving wheel and the driven wheel. The diameter of the driving wheel is larger than that of the driven wheel.

[0010] Further, a plurality of discharge ports are opened on one side of the transmission cylinder away from the driven wheel, and a cover shell is fixedly connected to the outer side of the side wall of the transmission cylinder at the discharge ports. One end of the cover shell is fixedly connected with a feeding pipe, and the feeding pipe is a concrete conveying hose. The feeding mechanism includes a discharge pipe, and the discharge pipe is fixedly connected to one end of the feeding pipe, and the discharge pipe is a rigid pipe.

[0011] Further, a water stop air bag is fixedly connected to the outer side of the pipe body of the discharge pipe on the side away from the material bucket. A through hole is opened at the top of the air bag body of the water stop air bag, and an exhaust valve is fixedly connected to the water stop air bag at the through hole.

[0012] Further, the exhaust valve includes three valve flaps, and the three valve flaps are all in a 120-degree fan shape. An air hole is opened at the bottom end of one side of the water stop air bag, and an air pipe is fixedly connected to the water stop air bag at the air hole.

[0013] Further, a plurality of support plates are fixedly connected to the outer side of the pipe body of the discharge pipe at equal intervals on the side close to the material bucket, and rollers are rotatably connected to the end parts of one side of the support plates.

[0014] Further, the transmission cylinder is fixedly connected to the bottom of the material bucket, and a material port is opened at one side between the transmission cylinder and the material bucket. The transmission cylinder and the material bucket are fixedly connected with the same valve at the material port.

Therefore, under the condition of using the mortar admixture to overcome the defects of self-compacting concrete, it can be poured into the steel pipe to achieve the effect of vibration-free and self-compacting; secondly, the agitation of the concrete can also ensure its fluidity during pouring, so it can be more fully and evenly filled into the steel pipe; therefore, this device can not only make the pouring process easier by eliminating vibration, but also ensure the compactness and uniformity of the concrete after pouring, thereby ensuring the safety and stability of the concrete structure.

[0019] 2. When pouring concrete into a steel pipe, it can be placed inside the steel pipe. While pouring the concrete, the feeding pipe is pulled to move the discharging pipe outward, so that the pouring process is more gradual and more conducive to ensuring the pouring quality. The air inside the steel pipe will be squeezed out from the exhaust valve when the concrete occupies the space inside the pipe, thus avoiding the formation of a vacuum area.

[0020] 3. Since the diameters of the steel pipes used in different parts of the steel pipe curtain are not necessarily the same, when pouring concrete into steel pipes of different diameters, the total length of the plate body and the plate sleeve can be adjusted after loosening the bolt, so that the three support plates can still support the discharging pipe at the axis of the steel pipe under different pipe diameters, thereby ensuring the stable progress of the pouring process.

[0028] Embodiment 1

[0029] Refer to the appendix Figure 1-2, this application provides a concrete pouring device inside a pipe curtain, including a material bucket 1, a transmission cylinder 2 and a driving mechanism. A stirring mechanism is provided in the material bucket 1, and the stirring mechanism is used to mix the concrete and the admixture evenly. When using this device, self-compacting concrete can be selected for pouring, and at the same time, the mortar admixture is mixed into the self-compacting concrete, and the stirring mechanism mixes the two evenly, so that the use defects of the self-compacting concrete can be overcome by the mortar admixture. Thus, not only the vibration process after pouring can be eliminated, but also the quality of the pipe curtain can be ensured. The stirring mechanism includes a connecting shaft 16 and a plurality of blades 17. The number of the blades 17 is several, and they are fixedly connected to the outside of the connecting shaft 16 at equal intervals. That is, when the blades 17 rotate with the connecting shaft 16, they can stir the material, so as to ensure the uniformity and fluidity of the concrete, and then facilitate the pouring process. A conveying mechanism is provided in the transmission cylinder 2, and the conveying mechanism is used to convey the evenly mixed concrete. The conveying mechanism includes a rotating shaft 11 and a spiral blade 12. The spiral blade 12 is fixedly connected to the outside of the rotating shaft 11. Through the high-speed rotation of the spiral blade 12, the concrete can be horizontally conveyed. The driving mechanism is used to drive the connecting shaft 16 and the rotating shaft 11 to rotate simultaneously, and the power source for driving the two to rotate is unique, so the maintenance process can be simplified and the overall energy efficiency can be improved. A feeding mechanism is provided on one side of the transmission cylinder 2, and the feeding structure is used to pour the material. After the material is conveyed by the spiral blade 12, it can be discharged by the feeding mechanism and then poured.

[0030] Preferably, the material bucket 1 is cylindrical. Since the running track of the blade 17 is circular, designing the material bucket 1 as cylindrical can avoid dead corners inside it and affect the evenness when stirring the material. And through holes are opened in the middle of both sides of the material bucket 1. The connecting shaft 16 penetrates through the material bucket 1 at the two through holes, and the connecting shaft 16 is rotationally connected to the material bucket 1 at the circular through holes. The material bucket 1 is rotationally sealed with the connecting shaft 16 at the circular through holes, so that material leakage or blockage of the through holes can be avoided. A housing 10 is fixedly connected to the outside of one end of the connecting shaft 16 on one side of the material bucket 1. A motor 1001 is fixedly connected to the inner wall of one side of the housing 10, and the motor 1001 is fixedly connected to the connecting shaft 16. The motor 1001 can be a servo motor. Since the servo motor can control the rotation speed, the stirring effect of the blade 17 on the concrete can be controlled accordingly.

[0031] Preferably, a second through hole is formed on one side of the transfer cylinder 2 away from the casing 10. The rotating shaft 11 is rotatably connected to the transfer cylinder 2 at the second through hole. The driving mechanism includes a driving wheel 15 and a driven wheel 13. The driving wheel 15 and the driven wheel 13 are respectively connected to one end of the connecting shaft 16 and the rotating shaft 11 by keys, and a same belt 14 is sleeved outside the driving wheel 15 and the driven wheel 13. The diameter of the driving wheel 15 is larger than that of the driven wheel 13. Using the larger-diameter driving wheel 15 to drive the smaller-diameter driven wheel 13 can achieve an acceleration effect. Since the concrete has viscosity, the blades 17 can stir the concrete at a slower speed, thereby reducing the load on the motor 1001. However, at the same time, through the acceleration effect of the driving wheel 15 and the driven wheel 13 on the rotating shaft 11, the spiral blades 12 can still rotate at a high speed. Therefore, the spiral blades 12 can have sufficient torque and power to convey the concrete.

[0032] Preferably, a plurality of discharge ports are formed on one side of the transfer cylinder 2 away from the driven wheel 13, and a cover 3 is fixedly connected to the side wall of the transfer cylinder 2 outside the discharge ports. The cover 3 is funnel-shaped, so it can gather the materials and make them enter the feeding pipe 4 in a more concentrated state. One end of the cover 3 is fixedly connected to the feeding pipe 4. The feeding pipe 4 is a concrete conveying hose. The flexible feeding pipe 4 can be used to adapt to the process of bending the feeding pipe 4 when the feeding mechanism is placed in the steel pipe for pouring operation. The feeding mechanism includes a discharge pipe 9. The discharge pipe 9 is fixedly connected to one end of the feeding pipe 4, and the discharge pipe 9 is a rigid pipe, so it can ensure the stability during discharging. A water stop airbag 8 is fixedly connected to the outer side of the pipe body of the discharge pipe 9 away from the material bucket 1. Since the concrete is often poured into the steel pipe by closing one pipe orifice and then pouring from the other pipe orifice, the water stop airbag 8 can form a sealed space with the plugging member after expansion. When filling the concrete into it, the concrete will gradually occupy the space and squeeze the air out from the valve at the through hole. Then, by pulling the feeding pipe 4, the discharge pipe 9 can gradually retreat. Therefore, the concrete can be gradually poured into the steel pipe to avoid generating a vacuum area in the steel pipe during this process. A through hole is formed at the top of the airbag body of the water stop airbag 8. The setting of the through hole is equivalent to opening openings at the top of both sides of the water stop airbag 8 and connecting the two openings with a tubular object. Therefore, the existence of the through hole will not affect the airtightness inside the water stop airbag 8. And an exhaust valve 801 is fixedly connected to the water stop airbag 8 at the through hole. The exhaust valve 801 includes three valves. The three valves are all in a 120-degree fan shape. The valves are made of plastic. Under normal conditions, the three valves are in a closed state. When the concrete occupies the internal space of the steel pipe and the air is squeezed, the air pressure will increase, so the three valves will be pushed open and discharged from the gaps between them. An air hole is formed at the bottom end of one side of the water stop airbag 8, and an air pipe 5 is fixedly connected to the water stop airbag 8 at the air hole. The air pipe 5 is used for inflating and deflating the water stop airbag 8, and a switch valve is provided on the air pipe 5.

[0033] Preferably, a plurality of support plates 7 are fixedly connected to the outside of the pipe body of the discharge pipe 9 at equal intervals on the side close to the material bucket 1. A roller 6 is rotatably connected to one end of the support plate 7. The support plate 7 and the roller 6 can support the discharge pipe 9 and ensure that it is made at the axis of the steel pipe. While supporting, the roller 6 can also ensure that the discharge pipe 9 can move. Therefore, the discharge pipe 9 can stably discharge materials.

[0034] Preferably, the transmission cylinder 2 is fixedly connected to the bottom of the material bucket 1, and a material port is opened on one side between the transmission cylinder 2 and the material bucket 1. The transmission cylinder 2 and the material bucket 1 are fixedly connected with the same valve at the material port. After the valve is closed, the unagitated material will not enter the transmission cylinder 2. The valve can be an electromagnetic valve, so the valve can be controlled outside the device. Both ends of the two sides of the bottom of the material bucket 1 are fixedly connected with support feet.

[0035] Preferably, the stirring control mechanism includes a controller, a timer and a horn. The motor 1001, the timer and the horn are all electrically connected to the controller. The controller is an 8051 single-chip microcomputer. The timer can be used to set the stirring duration according to the amount of the material, and the horn is used to give a reminder after reaching the stirring duration. The motor 1001 is a servo motor. In addition to being able to control the start and stop of the servo motor, the controller can also control its rotation speed during the process of stirring the material, so as to make the liquid flow generated in the material bucket 1 more complex and more conducive to uniform mixing.

[0036] Working principle: When pouring concrete into the steel pipe in the pipe curtain, the self-compacting concrete and the mortar admixture can be put into the material bucket 1, and then the motor 1001 is started. The motor 1001 drives the blade 17 to rotate through the connecting shaft 16, so as to stir the self-compacting concrete and the mortar admixture and make the two mix evenly.

[0037] After the materials in the material bucket 1 are mixed evenly, the discharge pipe 9 can be put into the steel pipe, and it can be pushed to the deepest part of the steel pipe by using the feeding pipe 4. Then, an air pump or an air cylinder is used to pump air into the air pipe 5, so that the water stop air bag 8 expands in the steel pipe, so as to achieve the effect of sealing the steel pipe. In addition, the roller 6 and the support plate 7 can support the discharge pipe 9 and make it located at the axis of the steel pipe.

[0038] Since the connecting shaft 16 can drive the driving wheel 15 to rotate while rotating, the driving wheel 15 can drive the driven wheel 13 to rotate through the belt 14, and the driven wheel 13 can drive the spiral blade 12 to rotate through the rotating shaft 11. Therefore, only by opening the valve and allowing the agitated materials in the material bucket 1 to fall into the transmission cylinder 2, the rotating spiral blade 12 can be used to convey the materials, so that the materials enter the feeding pipe 4 from the housing 3 and are finally discharged into the steel pipe from the discharge pipe 9, so as to carry out the concrete pouring.

[0039] During the above-mentioned pouring process, as the concrete continuously occupies the internal space of the steel pipe, the air inside it will be squeezed out from the exhaust valve 801; and during the pouring, the feeding pipe 4 can be slowly pulled, so that the discharging pipe 9 gradually moves outward, thereby gradually providing a filling space for the pouring of the concrete, so it is more conducive to controlling the pouring quality.

[0040] Embodiment 2

[0041] Refer to the attached Figure 3 , this application provides a concrete pouring device inside a pipe curtain. Compared with Embodiment 1, in order to ensure the stable progress of the pouring process of steel pipes with different diameters by this device, the support plate 7 includes a plate body 701 and a plate sleeve 703. The plate body 701 is rotatably connected to the roller 6. The plate sleeve 703 is sleeved outside the bottom end of the plate body 701. A threaded through hole is provided at the top end of one side of the plate sleeve 703, and a bolt 702 is threadedly connected to the plate sleeve 703 at the threaded through hole. After loosening the bolt 702, the total length of the plate body 701 and the plate sleeve 703 can be adjusted to adapt to steel pipes with different diameters. Since the water stop airbag 8 can adapt to the change in the diameter of the steel pipe through its own expansion, the sealing effect can still be ensured.

[0042] Working principle: When there are differences in the diameters of the steel pipes, the total length of the plate body 701 and the plate sleeve 703 can be adjusted after loosening the bolt 702, so as to ensure that the discharging pipe 9 can always be located at the axis of the steel pipe. In this case, the process of pulling the discharging pipe 9 outward can be more stable, so the process of pouring concrete using the discharging pipe 9 will also be more stable.

[0043] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
