[0048] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention. Example 1

[0049] Expansion of existing station buildings can improve the operational capacity of railway lines and make travel more convenient. The expansion of existing station buildings involves assembling the new station building structure and then connecting it to the existing structure using a jacking method.

[0050] Reference Figure 1 and Figure 2 The newly constructed station building structure includes a waiting level truss 101, a transfer passage 102 connected to the waiting level truss 101, and a skybridge structure 103 connected to the transfer passage 102. When jacking such a large-span structure, problems such as excessive pressure and abnormal alarms in the jacking hydraulic system occur. By monitoring and analyzing the jacking data from multiple points, the inventors of this application discovered that there were deviations in the jacking distances at different points in the jacking data, indicating that the overall structure was not jacked synchronously. Further investigation revealed that when these structures were connected by completely fixed connections, the asynchronous jacking caused the structure to jam, thus triggering the aforementioned alarm in the hydraulic system.

[0051] This embodiment provides a jacking system for newly built station structures, which can solve the above-mentioned problems.

[0052] Specifically, in the jacking system of the newly constructed station building, the connection structure between the transfer passage 102 and the waiting floor truss 101 refers to... Figure 4 ,Include:

[0053] The temporary hinged seat includes a central plate 11 and two limiting posts 12 symmetrical about the plane of the central plate 11. The central plate 11 slides between the two limiting posts 12 on the base (the transfer passage support frame 104 above the waiting floor truss 101 is said base). The limiting posts 12 are fixed on the transfer passage support frame 104.

[0054] The movable body (the steel beam of the transfer passage 102 is the movable body) is located between two limiting columns 12, and a vertically penetrating flat groove 2 is opened at the vertical center surface of the steel beam of the transfer passage 102, and the center plate 11 is located in the flat groove 2.

[0055] The connection structure between transfer passage 102 and overpass structure 103 is as follows: Figure 3 ,Include:

[0056] The temporary hinge seat includes a center plate 11 and two limiting posts 12 symmetrical about the plane of the center plate 11. The center plate 11 slides on the base (the sky bridge structure 103 is the base) between the two limiting posts 12, and the limiting posts 12 are fixed to the sky bridge structure 103.

[0057] The movable body (the steel beam of the transfer passage 102 is the movable body) is located between two limiting columns 12, and a vertically penetrating flat groove 2 is opened at the vertical center surface of the steel beam of the transfer passage 102, and the center plate 11 is located in the flat groove 2.

[0058] In this embodiment, the position of the movable body (the steel beam of the transfer passage 102 is the movable body) is allowed to move between the limiting posts 12 of the temporary hinge seat, and the position of the movable body (the steel beam of the transfer passage 102 is the movable body) is also allowed to move along the center plate 11. Figure 3 and Figure 4 The vertical direction is defined in the middle. While restricting the relative positions of the waiting floor truss 101, transfer passage 102, and skybridge structure 103 within the newly constructed station building structure, it also allows for a range of movement in certain directions. Therefore, while jacking the entire newly constructed station building structure, it avoids structural deformation and stress concentration caused by factors such as different jacking distances, temperature changes, and earthquakes, which could lead to jamming. This ensures that the large-span newly constructed station building structure can be smoothly jacked to the target position during large jacking displacements.

[0059] In this embodiment, refer to Figure 3 A sliding plate 3 is provided at the bottom of the central plate 11. The bottom of the sliding plate 3 is a sliding layer with a low coefficient of friction, such as a polytetrafluoroethylene (PTFE) pad. The sliding plate 3 is located between the two limiting posts 12. The load of the structure is further borne by the friction of the sliding surface, and the structure is allowed to interact in the horizontal direction.

[0060] In this embodiment, we continue to refer to... Figure 3 The width of the sliding plate 3 is greater than the width of the steel beam of the transfer passage 102. Guided by the sliding plate 3 extending a certain distance below, and with its greater width, this structure allows for a certain range of rotation if the steel beam of the transfer passage 102 is out of sync with the other two structures, further preventing jamming.

[0061] In this embodiment, we continue to refer to... Figure 3 The two side ends of the sliding plate 3 extend upward to form a limiting plate 1, which can prevent excessive stiffness deformation while ensuring a certain degree of freedom. Furthermore, the height of the limiting plate 1 is less than that of the movable body (102), thus avoiding interference.

[0062] In this embodiment, we continue to refer to... Figure 3 The movable body (102) is higher than the sliding plate 3, and a first support rib 4 and a second support rib 6, as well as a reinforcing rib 5, are provided between the movable body (102) and the sliding plate 3 on the central plate 11.

[0063] The first support rib 4 and the second support rib 6 are used to support the movable body (102).

[0064] The reinforcing rib 5 is used to increase the strength and rigidity of the center plate 11.

[0065] In this embodiment, a distance sensor is provided at the tail end of the slide rail in the jacking system. The distance sensor is used to measure the jacking distance of the newly built station structure on the slide rail.

[0066] The operating parameters of the power mechanism used to provide jacking force are adjusted based on the jacking distance feedback from the distance sensor.

[0067] The system employs both manual measurement and a real-time monitoring system for the jacking operation using the aforementioned distance sensor to precisely control the jacking synchronization and eliminate accumulated errors. If asynchronous lateral displacement exceeds the limit during the jacking process, the computer uses the pump station to adjust the oil pressure to actively correct the jacking cylinder.

[0068] For the newly constructed station structure in this embodiment, it will be jacked up using multiple parallel sliding rails. The distance sensor can be a laser rangefinder, which is fixedly installed at the end of each sliding rail to measure the jacking distance of the structure on each rail. The distance measured is the total jacking distance. The main function of the laser rangefinder is to measure the jacking distance of the structure on each axis during the jacking process; the obtained measurement data is used to verify whether the jacking distances of the structures on each sliding rail are consistent and synchronized. The measurement data will be automatically uploaded to the computer terminal in real time. If inconsistencies or deviations occur in the measured data across different axes, the computer terminal will automatically adjust the oil pressure of the hydraulic pump station to correct the deviation.

[0069] In this embodiment, refer to Figure 5 The jacking system includes a sliding shoe 15 that supports the structure of the newly built station building, and the sliding shoe 15 is slidably engaged with the slide rail 14;

[0070] A pointer 13 is set on the slide shoe 15, and a scale is set on the slide rail 14;

[0071] The pointer 13 is L-shaped, with one end mounted on the slide shoe 15 and the other end bent toward the slide rail 14 and close to the scale.

[0072] Pointer 13 is used to read the jacking distance of the structure on each slide rail 14, and can also be used to check whether each axis is synchronized. One worker is assigned to each slide rail 14 to record the readings and report the data in real time via walkie-talkie. With this implementation, accurate readings can be obtained quickly without the need for on-site use and proper placement of measuring tools.

[0073] In this embodiment, refer to Figure 1 and 6The front end of the newly built station building structure is equipped with a main beam 201 and a side guide beam 202.

[0074] The lower surface 204 of the main beam 201 is parallel to the upper surface of the new station building structure, and the upper surface 203 of the main beam 201 is inclined to its upper surface and the end that connects to the new station building structure is the highest.

[0075] The main beam 201 and the side guide beam 202 are located at the front end of the newly built station building structure being jacked up. During jacking, they can reach the existing structure before the new station building structure and be supported, reducing the deformation of the new station building structure and lowering the difficulty of jacking up. The main beam 201 and the side guide beam 202 have small mass and are designed as truss structures, which have a certain resistance to deformation, thereby further reducing the degree of deformation of the structure being jacked up.

[0076] In this embodiment, the lower surface of the main beam 201 is parallel to the upper surface of the new station building structure, and the upper surface of the first guide beam 201 is inclined to its upper surface, with the end that connects to the new station building structure being the highest. The upper surface of the main beam 201 is inclined downward at the front end, which helps to reduce the weight of the main beam 201, thereby maintaining its rigidity and improving the jacking accuracy.

[0077] In this embodiment, a main beam 201 is positioned at the beginning of the new station building structure and connected to the top of the new station building structure 100. Through this technical solution, the existing station building 500 (refer to...) Figures 8 to 12 The guide beam support frame 501 on the ) can lift the first guide beam 201, and after the jacking is completed, the guide beam support frame 501 can serve as a support during the beam lowering stage.

[0078] In this embodiment, the jacking system refers to... Figure 7 It also includes:

[0079] The mid-stage lifting cylinder 302 is used to provide upward support for the newly built station structure during the jacking process;

[0080] The intermediate lifting cylinder is installed on the existing concrete column on the existing platform.

[0081] Pushing the button:

[0082] S1: The main beam 201 and the side guide beam 202 arrive at the existing platform 400 before the newly built station building steel structure 100, and are supported by the temporary support frame of the guide beam set on the existing platform 400;

[0083] In this embodiment, refer to Figure 8A lifting cylinder 302 is installed on the temporary support frame of the guide beam. The lifting cylinder 302 can adjust the extension length of the cylinder rod according to the height of the pushed structure monitored. If the height of the pushed structure indicates that its deformation is too large, the cylinder rod of the lifting cylinder 302 will extend upward to support the guide beam and reduce the deformation.

[0084] S2: The new station building steel structure 100 reaches the existing platform 400 and is supported by the temporary main structure support frame set on the existing platform 400, after which the jacking is paused. Figure 8 As shown;

[0085] In this embodiment, refer to Figure 8 A sliding cylinder 301 is installed on the temporary support frame of the main structure. The sliding cylinder 301 can adjust the extension length of the cylinder rod according to the height of the pushed structure monitored. If the height of the pushed structure indicates that its deformation is too large, the cylinder rod of the sliding cylinder 301 will extend upward to support the steel structure 100 of the new station building, thereby reducing the deformation.

[0086] S3: Remove the temporary support frame for the guide beam, as follows: Figure 9 As shown; continue pushing, during which the two sliding cylinders 301 provide alternating support and their positions change along the pushing direction, as follows. Figures 10 to 12 As shown, the main beam 201 and the side guide beam 202 reach the existing station building 500, and the main beam 201 is supported by the guide beam support frame 501 installed on the existing station building 500;

[0087] S4: Continue pushing until the newly built station building steel structure 100 reaches the existing station building 500, and then remove the front sections of the main beam 201 and the side guide beam 202;

[0088] Among them, reference Figure 7 The temporary support frame for the guide beam and the temporary support frame for the main structure are erected on existing concrete columns on the existing platform 400. Therefore, the jacking method in this embodiment utilizes the existing concrete columns on the existing platform 400. The temporary support frame for the guide beam and the temporary support frame for the main structure are erected on these existing concrete columns. The lifting cylinder 302 on the temporary support frame for the guide beam and the sliding cylinder 301 on the temporary support frame for the main structure support lift the guide beam and the newly built station building steel structure during the jacking stroke, reducing deformation and improving jacking accuracy. By cleverly utilizing the existing structure, the amount of work is saved and time is reduced, representing a significant improvement.

[0089] This application claims priority to patent application CN 116220368A. In

[0041] of the publication text of that application, it is described that "the temporary sliding support for platform II2 adopts a stepped lattice support frame 20, which includes a structural truss sliding platform 23 and a guide beam temporary support pier 22. The structural truss sliding platform 23 adopts a double-I-beam platform. A structural truss fixed sliding shoe 13, jacks 18, limit rods 21, and a guide beam temporary support pier 22 are installed on the upper part of the structural truss sliding platform 23. The guide beam temporary support pier 22 is installed on the structural truss sliding platform 23. A guide beam fixed sliding shoe support 24 is installed on the upper part of the guide beam temporary support pier 22. A guide beam fixed sliding shoe 12 is installed on the top of the guide beam fixed sliding shoe support 24 to ensure that the elevation of the guide beam fixed sliding shoe 12 on the upper part of the guide beam temporary support pier 22 is consistent with the elevation of the lower chord of the guide beam 9 structure."

[0090] Platform II2 is the existing platform 400 mentioned in this application;

[0091] The structural truss sliding platform 23 is the temporary support frame for the main structure described in this application;

[0092] The temporary support pier 22 for the guide beam is the temporary support frame for the guide beam described in this application.

[0093] Furthermore, S1, S2, S3 and S4 can be spaced out over a relatively long period of time, and do not need to be partially or fully completed within a single window period. Therefore, the requirement for the duration of the window period is low, which further improves the applicability of the jacking method provided in this embodiment and makes the expansion of existing stations more feasible.

[0094] In this embodiment, the existing platform 400 is further utilized during the construction of the temporary support frame for the guide beam and the temporary support frame for the main structure. The temporary support frame for the guide beam and the temporary support frame for the main structure are connected to the existing concrete columns of the existing platform 400 via embedded steel plates. In this technical solution, the temporary support frame for the guide beam and the temporary support frame for the main structure can increase stability by connecting to the embedded steel plates of the existing concrete columns, while the existing concrete columns can also be supported and reinforced by the temporary support frame for the guide beam and the temporary support frame for the main structure.

[0095] In this embodiment, refer to Figure 7 The jacking angle is corrected by the correction cylinders 3 and 7 on the temporary support frame of the guide beam, so as to correct the deviation of the jacking direction more timely and effectively.

[0096] In this embodiment, the second support frame 305 is also provided with a guide beam slide 308. The guide beam slide 308 is provided with a sliding surface layer or rollers with a low coefficient of friction, which can reduce the friction force when the guide beam moves while supporting the guide beam.

[0097] Reference Figure 13 and Figure 14 The jacking system described in this embodiment further includes:

[0098] A pusher rail clamp is installed on the slide rail 14 to clamp the slide rail 14, so that the pusher oil cylinder installed on the pusher rail clamp pushes the slide shoe to slide in the pusher direction A;

[0099] The pusher rail clamp includes:

[0100] Box 405, the left inner wall and the right inner wall of box 405 are mirror symmetrical with respect to the left and right central sections of box 405, the left inner wall and the right inner wall of box 405 have an angle with the left and right central sections, and the left inner wall and the right inner wall of box 405 are close to each other at the front end of the pushing direction.

[0101] Wedge block 404, one wedge block 404 is provided on the left inner wall and one wedge block 404 on the right inner wall of the housing 405, and the side elevation of the two wedge blocks 404 on the opposite side is parallel to the slide rail 14.

[0102] The screw sleeve 402 is inserted into the rear end face of the housing 405 and fixed to the housing 405. The axis of the left screw sleeve 402 is parallel to the left inner wall of the housing 405, and the axis of the right screw sleeve 402 is parallel to the right inner wall of the housing 405. The left and right sides are the left and right sides of the pushing direction A.

[0103] The screw 407 passes through the rear end face of the housing 405 and is connected to the wedge block 404. A nut 401 is screwed onto one end of the screw 407 outside the housing 405.

[0104] Spring 403 is sleeved on a section of screw 407 located inside housing 405, with one end of spring 403 connected to screw 407 and the other end connected to wedge block 404;

[0105] A connector 406 is provided above the jacking rail clamp to connect with the jacking device.

[0106] When the pusher pushes, when the spring 403 is compressed and deformed to its limit, the wedge block 404 clamps the slide rail 14. The clamping rail provides a reaction force, the pusher (pushing cylinder) extends forward, and the structure slides forward.

[0107] When the pusher is not pushing, the spring 403 is relaxed, and the wedge block 404 moves backward relative to the housing 405, which does not cause excessive resistance to the pusher cylinder.

[0108] The push rail clamp provided in this embodiment uses the inclined surface between the wedge block 404 and the inner wall of the box 405 to use the reaction force of the push cylinder on the rail clamp to clamp the slide rail 14. The clamping force is large enough to ensure the stability of the position of the rail clamp, thereby improving the accuracy of the push distance.

[0109] Furthermore, with the help of the spring 403 between the screw 407 and the wedge block 404, when no pushing is being performed, the spring 403 relaxes and the wedge block 404 moves backward relative to the housing 405, so as not to cause excessive resistance to the pusher cylinder.

[0110] Furthermore, by changing the position of the nut 401 on the screw 407, the pusher rail clamp can be used on slide rails 14 of different widths.
