Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to a high pier pumping structure. Background Art
[0002] During bridge construction, concrete needs to be pumped to the section that needs to be poured on top of the pier. As the pier height increases, the concrete needs to be pumped to a higher position. During pumping, problems such as insufficient pressure and discontinuous pumping are prone to occur, which can easily cause pipe blockage. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a high pier pumping structure.
[0004] The purpose of the utility model is achieved through the following technical solutions: A high pier pumping structure, comprising:
[0005] A main pump, wherein the main pump is arranged on the ground and an inlet of the main pump is connected to a concrete source;
[0006] A relay pump, wherein the relay pump is arranged on the pier top;
[0007] A vertical pipeline is provided along the surface of the pier body, wherein the bottom end of the vertical pipeline is connected to the outlet of the main pump, and the top end of the vertical pipeline is connected to the inlet of the relay pump;
[0008] A transverse pipe, one end of which is connected to the outlet of the relay pump, and the other end of which is connected to the segment casting location.
[0009] The utility model provides a relay pump which is arranged on the pier top. After the main ground pump pumps concrete onto the pier top, the relay pump is used to pump the concrete for a second time, which greatly reduces the load of the main ground pump. At the same time, the concrete has sufficient pressure and is not prone to pipe blockage.
[0010] In some embodiments, a spare vertical pipe is further provided on the pier body, parallel to the vertical pipe, with both ends of the spare vertical pipe left vacant. By providing the spare vertical pipe, in the event of an accident with the vertical pipe, the spare vertical pipe can be connected to avoid delaying the construction period.
[0011] In some embodiments, the vertical pipes are also coated with insulation material. In extreme temperatures in summer or winter, the pumping distance of high pier pumping is long. To avoid affecting the performance of concrete during the concrete pumping process, the vertical pipes are coated with insulation material to keep the concrete warm.
[0012] In some embodiments, the transverse pipeline includes a main pipeline and branch pipelines. One end of the main pipeline connects to the outlet of the relay pump and the other end connects to the inlet of the reversing valve. Two branch pipelines connect to the two outlets of the reversing valve at one end and to the pouring points on both sides of the pier at the other end. By providing branch pipelines, concrete can be pumped to both sides of the pier. The reversing valve can be used to adjust the pumping volume on both sides of the pier.
[0013] In some embodiments, the reversing valve comprises a hydraulic reversing valve, which is stable and reliable in operation and can operate stably under adverse conditions to ensure continuous pumping.
[0014] In some embodiments, the pier body is pre-embedded with several mounting components at evenly spaced intervals vertically. These mounting components are fixed with U-shaped clamps that clamp the vertical pipes. The mounting components, in conjunction with the U-shaped clamps, facilitate positioning of the vertical pipes, preventing them from detaching from the pier body.
[0015] In some embodiments, the vertical pipeline includes a plurality of vertical sub-pipes, which are connected end to end to form a vertical pipeline. By dividing the vertical pipeline into a plurality of vertical sub-pipes, transportation is facilitated.
[0016] In some embodiments, the vertical sub-pipes are connected by clamps. Using clamps to connect the vertical sub-pipes is convenient and quick, does not require welding, has high installation speed, and is easy to disassemble. When a vertical pipe fails, the faulty part of the vertical pipe can be quickly repaired.
[0017] In some embodiments, a hand chain hoist is mounted on the mounting member, and the hoist's lifting chain is connected to the clamp. During concrete pumping, the vertical pipe is long and filled with concrete, resulting in a heavy weight. The clamp alone cannot effectively support the weight of the vertical pipe, so the hand chain hoist is provided to lift the vertical pipe.
[0018] The utility model has the following advantages:
[0019] The utility model provides a main pump and a relay pump. After the ground pump pumps the concrete to the top of the pier, the relay pump pumps the concrete to the pouring site, thereby reducing the load of the main pump. At the same time, the relay pump ensures the pressure of the concrete during pumping and avoids pipe blockage. At the same time, the utility model provides thermal insulation materials on the vertical pipeline to avoid the influence of extreme temperature conditions on the performance of the concrete. The utility model also provides a hand winch on the pier body to lift the vertical pipeline to avoid danger caused by the excessive weight of the vertical pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in a variety of different configurations.
[0025] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0026] like Figure 1-Figure 3 As shown, a high pier pumping structure includes a main pump 1, a relay pump 2, a vertical pipeline 3 and a horizontal pipeline 4;
[0027] The main pump 1 is arranged on the ground, and the inlet of the main pump 1 is connected to the concrete source;
[0028] The relay pump 2 is arranged on the top of the pier;
[0029] The vertical pipe 3 is arranged along the surface of the pier body, the bottom end of the vertical pipe 3 is connected to the outlet of the main pump 1, and the top end is connected to the inlet of the relay pump 2;
[0030] One end of the transverse pipe 4 is connected to the outlet of the relay pump 2, and the other end is connected to the segment casting location.
[0031] Specifically, in this embodiment, the main pump 1 is a diesel pump with a model of SY5143THBE-10023C-10S, the relay pump 2 is an electric pump with a model of HBT8022C-5, the inner diameters of the vertical pipe 3 and the spare vertical pipe 6 are both 12.5 cm, and during the pumping process, the vertical pipe 3 pumps 6000-8000 m 3In this embodiment, a relay pump 2 is provided to pump the concrete on the pier top by the main pump 1 for the second time, thereby reducing the load on the main pump 1 and ensuring that the concrete has sufficient pressure to avoid pipe blockage caused by concrete.
[0032] Preferably, a spare vertical pipe 6 is further included. The spare vertical pipe 6 is arranged on the pier body in parallel with the vertical pipe 3, and the upper and lower ends of the spare vertical pipe 6 are both vacant. In this embodiment, by providing the spare vertical pipe 6, if the main pipe 41 is accidentally blocked, the spare vertical pipe 6 can be connected to the main pump 1 and the relay pump 2 to avoid affecting the construction period.
[0033] Preferably, the vertical pipe 3 is also coated with a thermal insulation material. Due to the long length of the vertical pipe 3, the concrete resides in the vertical pipe 3 for a long time during concrete pumping, making it susceptible to the influence of ambient temperature. To prevent the ambient temperature from affecting the performance of the concrete, the vertical pipe 3 is coated with a thermal insulation material. Specifically, in this embodiment, the thermal insulation material is aerogel felt, which has high thermal insulation properties. Furthermore, aerogel felt is relatively hydrophobic, preventing rainwater accumulation from increasing the weight of the vertical pipe 3. Furthermore, the aerogel felt is lightweight and easy to cut, facilitating the coating construction.
[0034] Preferably, the transverse pipe 4 comprises a main pipe 41 and branch pipes 42. One end of the main pipe 41 connects to the outlet of the relay pump 2 and the other end connects to the inlet of the reversing valve 5. The two branch pipes 42 connect to the two outlets of the reversing valve 5 at one end and to the pouring points on either side of the pier at the other end. In this embodiment, two branch pipes 42 are provided to allow concrete to be pumped to both sides of the pier. To ensure weight balance on both sides of the pier, and to limit the unbalanced weight to no more than 8 tons during pouring, a reversing valve 5 is provided. Through the reversing valve 5, concrete is intermittently poured to both sides of the pier, ensuring weight balance on both sides.
[0035] Preferably, the reversing valve 5 comprises a hydraulic reversing valve 5. The hydraulic reversing valve 5 works stably and reliably, operates stably under adverse conditions, and ensures the continuity of pumping.
[0036] Preferably, a plurality of mounting components 7 are pre-embedded at uniform vertical intervals on the pier body, and a U-shaped clamp 8 is fixedly provided on the mounting component 7 , and the U-shaped clamp 8 clamps the vertical pipe 3 .
[0037] In this embodiment, the mounting component 7 includes a climbing cone and an anchor plate. The climbing cone is pre-embedded in the pier, and the anchor plate is fixed to the pier via the climbing cone. A U-shaped clamp 8 is fixedly connected to the anchor plate. The U-shaped clamp limits the vertical pipe 3 and allows it to be installed along the surface of the pier.
[0038] Preferably, the vertical pipe 3 includes a plurality of vertical sub-pipes 31, and the plurality of vertical sub-pipes 31 are connected end to end to form the vertical pipe 3. By splitting the vertical pipe 3 into a plurality of vertical sub-pipes 31, transportation is facilitated.
[0039] Preferably, the vertical sub-pipes 31 are connected by clamps 32. Compared with welding connection and flange connection, the vertical sub-pipes 31 are connected by clamps 32, which saves welding and bolting steps, thereby improving construction efficiency. At the same time, the clamps 32 facilitate the connection of the hand hoist 9.
[0040] Preferably, a hand hoist 9 is hung on the mounting component 7, and the lifting chain of the hand hoist 9 is connected to the clamp 32. Since the vertical pipe 3 is filled with concrete during the pumping process, and the density of the concrete is relatively high, the weight of the vertical pipe 3 during the pumping process is relatively large, and the U-shaped clamp 8 is not sufficient to support the weight of the vertical pipe 3. Therefore, a hand hoist 9 is provided to bear the weight of the vertical pipe 3. Specifically, the hand hoist 9 is a commonly used device for those skilled in the art, and its structure is not described in detail here. The hand hoist 9 is hung on the anchor plate, and the clamp 32 on the vertical pipe 3 is hung on the lifting chain of the hand hoist 9. The vertical pipe 3 is lifted by the hand hoist 9. In the present utility model, a 10-ton hand hoist 9 is selected.
[0041] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation on the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the above-described technical content to make many possible changes and modifications to the present invention, or modify it into an equivalent embodiment with equivalent variations. Therefore, any changes, modifications, equivalent variations, and modifications made to the above embodiments based on the technology of the present invention that do not depart from the content of the present invention are within the scope of protection of the present invention.
