Description

Technical Field

[0001] The utility model relates to the technical field of pipe jacking construction, in particular to a support platform for pipe jacking construction. Background Technique

[0002] Pipe jacking construction is a trenchless construction method, which is a pipeline laying construction technology with little or no excavation. The pipe jacking method of construction is to generate jacking force with the help of jacking equipment in the working pit, overcome the friction between the pipeline and the surrounding soil, jack the pipeline into the soil according to the designed slope, and transport the soil away. After one pipe is jacked into the soil layer, the second pipe is lowered and the jacking continues. Its principle is to use the thrust of the main jacking oil cylinders and between the pipelines and the relay chambers, etc., to push the tool pipe or the tunneling machine from the working pit through the soil layer until it is hoisted in the receiving pit. The pipeline follows closely behind the tool pipe or the tunneling machine and is buried between the two pits. During the pipe jacking construction process, in order to ensure that the pipe fittings can be jacked along the required path during pipe jacking, a support platform for pipe jacking construction is arranged below the pipe jacking.

[0003] The Chinese Patent Network published a long-distance pipe jacking construction device with the publication number CN215721223U, including a foundation pit well. One side inside the foundation pit well is provided with a cement baffle. One side of the cement baffle is fixedly connected with a hydraulic unit. One end of the hydraulic unit is connected with a hydraulic rod. The other end of the hydraulic rod is fixedly connected with a top plate. One side below the top plate is provided with a support frame. One side above the support frame is provided with a cement pipe. A through hole is opened on one side inside the foundation pit well. The cement pipe penetrates through the inside of the foundation pit well. One end of the cement pipe is connected with a tool pipe. One side of the tool pipe is fixedly connected with a shield machine. In the utility model, by arranging arc-shaped protrusions on the cement pipe, the arc-shaped protrusions can connect the two ends of the cement pipe during the turning construction of the cement pipe, reduce the gap between the cement pipes, and a rubber sealing ring and a metal gasket are arranged on the cement pipe. The rubber sealing ring and the metal gasket can seal the gap between the cement pipes to prevent water leakage when the cement pipes are in use.

[0004] When transporting the pipeline to the guide rail, the above device has no protective measures and completely relies on the traction of the crane. The pipeline orientation is often inconsistent with the guide rail direction, so that when workers are actually operating, they still need to manually adjust the pipeline orientation, which is time-consuming, laborious and unsafe. Therefore, a support platform for pipe jacking construction is proposed. Content of the Utility Model

[0029] In this embodiment, by arranging the support mechanism 2, the pipe guide rails 210 suspended by the crane can be made to fall onto the guide rails 210 in the same direction. By turning on the hydraulic jack 21 and the motor 23, the inner side surface of the rotating plate 26 can be made to fit the surface of the pipe, and then the pipe is driven to rotate so that the direction of the pipe is the same as that of the guide rails 210, eliminating the need for multiple people to jointly adjust the pipe direction, saving time and effort and being safer.

[0030] Embodiment 2

[0031] As Figures 1-5 shown in the figure, based on the same concept as the above Embodiment 1, this embodiment also proposes that the jacking mechanism 3 includes a support plate 31 and a jacking ring 38. The right end surfaces of a set of guide rails 210 are respectively fixedly connected to the left side of the support plate 31. Two sliding sleeves 34 are respectively sleeved on the surfaces of the set of guide rails 210. On the inner side surfaces of the two sliding sleeves 34, support columns 35 are respectively fixedly arranged. On the top surfaces of the support columns 35, support posts 36 are fixedly arranged. On the right side of the jacking ring 38, a plurality of limit rods 37 are respectively fixedly arranged. The right ends of the plurality of limit rods 37 respectively penetrate through the left side of the support plate 31 and extend to the right side of the support plate. On the left side surface of the support plate 31, a jacking cylinder 32 is fixedly arranged. The output end surface of the jacking cylinder 32 is fixedly connected to the right side surface of the support post 36. Inside the jacking ring 38, a connector is fixedly arranged. The left side surface of the support post 36 is fixedly connected to the right side surface of the connector.

[0032] In this embodiment, by providing a jacking mechanism 3, the track on the guide rail 210 can be stably pushed. A plurality of limit rods 37 are provided and a sliding sleeve 34 is provided on the guide rail 210 to limit and control the advancing direction of the jacking ring 38, making the jacking ring 38 more stable when jacking to the left.

[0033] During use, the device is arranged in the working well. When the crane lowers the pipeline into the working well, the hydraulic jack 21 is turned on. The output end of the hydraulic jack 21 can move the moving plate 22 up and down, moving the moving plate 22 and the rotating plate 26 to a position higher than the guide rail 210. When the crane lowers the pipeline, the orientation of the pipeline cannot fit well with the direction of the track 210. At this time, the motor 23 is turned on. The output end of the motor 23 can make the gear A 24 rotate, further driving the gear B 25 to rotate in the opposite direction, and at the same time making the rotating plate 26 rotate in the opposite direction. By adjusting the direction of the rotating plate 26 through the motor 23, the concave part in the middle of the rotating plate 26 is made to fit the pipeline to be lowered. Then the crane slowly lowers the pipeline, making the pipeline contact the rotating plate 26. The motor 23 is controlled again to make the rotating plate 26 rotate, adjusting the orientation of the pipeline to be consistent with the guide rail. After the adjustment is completed, the hydraulic jack 21 is slowly moved downward, so that the pipeline is slowly placed on the guide rail 210 under the action of the crane and the hydraulic jack 21. After the placement is completed, the crane releases and the hydraulic jack 21 continues to descend, making the height of the rotating plate 26 lower than the guide rail 210, so that the weight of the entire pipeline is supported by the guide rail 210. At this time, the jacking cylinder 32 is turned on. The output end of the jacking cylinder 32 makes the support column 36 move to the left. While the support column 36 moves to the left, it drives the sliding sleeve 34, the support column 35, and the jacking ring 38 to move to the left, so that the left side of the jacking ring 38 contacts the right side of the pipeline and pushes the pipeline to the left, making the pipeline move to the left along the guide rail 210. After the jacking cylinder 32 jacks to the maximum distance, the jacking cylinder 32 and the jacking ring 38 are returned to their original positions, and the operation is repeated.

[0034] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
