[0026] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0027] Example 1

[0028] Existing station buildings can be expanded to improve the operational capacity of railway lines and make travel more convenient. After the structure of the new station building is assembled (or temporarily) it is connected to the existing structure by jacking to achieve the expansion of the existing station building.

[0029] Reference Figure 1 This embodiment provides a guide beam for a newly built station building structure during jacking, which is arranged in front of the newly built station building structure 100, and the guide beam includes:

[0030] The first section 210 is connected to the new station building 100 structure;

[0031] The second section 220 is located in front of the first section 210. The lower surface 224 of the second section 220 is parallel to the upper surface of the newly built station building structure 100. The upper surface 223 of the guide beam is inclined to its upper surface and the end connected to the first section 210 is the highest.

[0032] The guide beam provided in this embodiment has a lighter front end, which can maintain the rigidity of the entire guide beam and reduce deflection and deformation, thereby improving the jacking accuracy.

[0033] In this embodiment, rods are arranged on the diagonal lines of the guide beam in the horizontal plane, so as to enhance the rigidity of the guide beam and reduce its weight as much as possible, thereby avoiding excessive deflection and deformation.

[0034] In this embodiment, the first section 210 of the guide beam is disposed at the head end of the newly built station building structure 100 and the guide beam is connected above the newly built station building structure 100 .

[0035] This application claims the priority of the patent application with publication number CN 116220368A. In the publication text of this application, it is recorded in

[0043] that "the guide beam 9 includes the floor truss guide beam and the overpass guide beam, and the guide beam 9 adopts an "L"-shaped structure and is connected to the upper front end of the existing hard cross beam 17":

[0036] The guide beam 9 is the guide beam in this application.

[0037] Reference Figure 2 This embodiment also provides a guide beam group for the newly built station building structure during jacking, including the above-mentioned guide beam 201.

[0038] In the guide beam group, the guide beam 201 is arranged in the middle, and auxiliary guide beams 202 are arranged on both sides of the guide beam 201. In the lateral direction, in addition to the guide beam 201, auxiliary guide beams 202 are also arranged. During the jacking construction, the guide beam 201 and the auxiliary guide beams can be simultaneously or successively mounted on the front support structure. This technical solution can better play the role of the guide beam (auxiliary guide beam) for the structure with a large span in the lateral direction and reduce the deflection deformation.

[0039] In this embodiment, 4 rows of guide beams 201 and 2 rows of auxiliary guide beams 202 are included; the 4 rows of guide beams 201 and the 2 rows of auxiliary guide beams 202 are symmetrically arranged relative to the center line of the newly built station building structure 100;

[0040] Furthermore, the distance between the two rows of guide beams 201 in the middle is smaller than the distance between the two rows of guide beams 201 on the same side.

[0041] In this embodiment, the newly-built station building structure 100 that is pushed up includes a waiting layer truss 101, a transfer passage 102, and a sky bridge structure 103. The transfer passage 102 and the sky bridge structure 103 are sequentially arranged on both sides of the waiting layer truss 101.

[0042] The guide beam 201 is connected to the waiting layer truss 101 , and the auxiliary guide beam 202 is connected to the overpass structure 103 .

[0043] The auxiliary guide beam 202 is connected to the bottom plate of the overpass structure 103 .

[0044] The auxiliary guide beam 202 is a vertical single-layer truss structure; that is, no vertical rods are provided in the auxiliary guide beam 202, and the rods in the horizontal direction (ie, the pushing direction) are all in a horizontal plane.

[0045] In order to reduce the deflection deformation in this embodiment, the diameter of the rods arranged in the pushing direction of each auxiliary guide beam 202 is gradually reduced in the pushing direction.

[0046] In this embodiment, rods are provided on the diagonal lines of the auxiliary guide beam 202 in the horizontal plane to enhance its rigidity.

[0047] In this embodiment, a guide beam group is set at the front end of the newly-built station building structure 100 being pushed, and the guide beam 201 and the auxiliary guide beam 202 are located at the front end of the newly-built station building structure 100 being pushed. When pushing, they can reach the existing structure before the newly-built station building structure 100 and thus be supported, thereby reducing the deformation of the newly-built station building structure and reducing the difficulty of pushing. Through the structural setting, the guide beam 201 and the auxiliary guide beam 202 have a small mass and have a certain anti-deformation ability by being set as a truss structure, thereby further reducing the deformation degree of the pushed structure.

[0048] Pushing:

[0049] S1: The guide beam 201 and the auxiliary guide beam 202 arrive at the existing platform 400 before the newly built station building structure 100, and are supported by the temporary guide beam support frame provided on the existing platform 400;

[0050] In this embodiment, refer to Figure 3 A lifting cylinder 302 is arranged 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 monitored height of the pushed structure. If the height of the pushed structure shows that its deformation is too large, the cylinder rod of the lifting cylinder 302 will extend upward to lift the guide beam to reduce the deformation.

[0051] S2: The newly built station building structure 100 arrives at the existing platform 400 and is lifted by the temporary support frame of the main structure provided on the existing platform 400, and then the top pushing is suspended. Figure 3 As shown;

[0052] In this embodiment, refer to Figure 3 A sliding cylinder 301 is arranged 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 monitored height of the pushed structure. If the height of the pushed structure shows that its deformation is too large, the cylinder rod of the sliding cylinder 301 will extend upward to lift the newly built station building structure 100 to reduce the deformation.

[0053] S3: Remove the temporary support frame of the guide beam, such as Figure 4 Continue pushing, with the help of the alternating support of the two sliding cylinders 301 and the position change of the two sliding cylinders along the pushing direction, as shown Figures 5 to 7 As shown, the guide beam 201 and the auxiliary guide beam 202 arrive at the existing station building 500, and the guide beam 201 is lifted by the guide beam support frame 501 provided on the existing station building 500;

[0054] S4: Continue pushing until the newly built station building structure 100 reaches the existing station building 500, and remove the front section of the guide beam 201 and the auxiliary guide beam 202;

[0055] The temporary support frame for the guide beam and the temporary support frame for the main structure are built on the existing concrete columns set up on the existing platform 400. The temporary support frame for the guide beam and the temporary support frame for the main structure are built on the existing concrete columns on the existing platform 400. 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 lift the guide beam and the newly built station building structure during the jacking process, reducing deformation and improving jacking accuracy. By cleverly utilizing the existing structure, the engineering workload and time are saved, which is a significant improvement.

[0056] Furthermore, there can be a long interval between S1, S2, S3 and S4, and they do not have to be partially or completely completed in one window period, so the requirement for the length of the window period is low.

[0057] In this embodiment, refer to Figures 1 to 7 , a guide beam 201 is arranged at the head end of the newly built station building structure 100 and the guide beam 201 is connected above the newly built station building structure 100. Through this technical solution, the guide beam support frame 501 on the existing station building 500 can lift the guide beam 201, and after the jacking is completed, the guide beam support frame 501 can serve as a support in the beam dropping stage.

[0058] In this embodiment, the lower surface of the guide beam 201 is parallel to the upper surface of the newly built station building structure 100, and the upper surface of the guide beam 201 is inclined to the upper surface thereof and the end connected to the newly built station building structure 100 is the highest. Figure 1 The upper surface of the guide beam 201 is tilted downward at the front end, which is conducive to reducing the weight of the guide beam 201, thereby maintaining its rigidity and improving the push accuracy. The lower surface is parallel to the horizontal plane, ensuring that the guide beam 201 can be stably supported by the existing structure.
