Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, in particular to a cooperative bridge temporary support system for soft soil foundation. Background Art

[0002] Pushing construction is a process of pushing the bridge structure to a designated position through guide beams, jacks and sliding systems. It has the advantages of simple construction, high safety and little impact on existing traffic, and is widely used in bridge engineering construction.

[0003] The steps of jacking construction are as follows: Figure 1 As shown:

[0004] 1. Set up temporary supports and working platforms, and assemble beams and guide beams;

[0005] 2. Guide frame on guide beam;

[0006] 3. Push into place;

[0007] 4. Remove the guide beams, drop beams, and temporary facilities.

[0008] The jacking method requires the erection of temporary supports, but due to the varying geological conditions of the project, it is prone to encountering soft soil foundations. Soft soil foundations have a low bearing capacity, and if temporary supports are erected on soft soil foundations, they will be subjected to the upper load, causing significant settlement of the foundation and supports. In this case, the temporary supports are difficult to support the superstructure, which is a major construction problem.

[0009] If the settlement of temporary supports is to be controlled, the bearing capacity of soft soil foundation can be improved by ground treatment. However, this method requires a large investment, and the project cost is too high for temporary facilities such as construction supports.

[0010] For example, the support system device for a large cantilever cap beam on a soft foundation disclosed in the Chinese utility model patent application with an authorization announcement date of 2021.04.13 and an authorization announcement number of CN 212956140U includes a vertical support frame, two longitudinal steel beams and a number of longitudinally distributed steel pipe piles on both sides of the pier's base. A driving lane is provided between the two steel pipe piles on the same side of the pier. The steel pipe piles include two pairs of steel pipes inserted in the ground. The two steel pipes in the same pair of steel pipes are distributed transversely and connected together by the pile steel longitudinal beams. The pile steel longitudinal beams on the two pairs of steel pipes are connected together by a lower steel cross beam. A vertical support frame is provided on the lower steel cross beam. The longitudinal beam is supported on all the vertical support frames, and the two longitudinal steel beams are connected together by a number of longitudinally distributed connecting steel bars.

[0011] In the above-mentioned existing technologies, the large cantilever cap beam of the weak foundation is supported, but it is supported by non-elastic materials such as upper steel plates, lower steel plates, rigid rib plates, and inclined steel plates. For weak foundations that are prone to settlement, there are certain safety hazards.

[0012] Therefore, how to effectively support the bridge based on the characteristics of the soft foundation is a technical problem that needs to be solved urgently. Utility Model Content

[0013] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a collaborative temporary bridge support system for soft soil foundations, which solves the problem of potential safety hazards in bridge support when encountering soft foundations that are prone to settlement.

[0014] The technical solution of this application is:

[0015] A collaborative temporary bridge support system for soft soil foundations includes a temporary support structure supported below a crossbeam, the temporary support structure including a sliding assembly disposed at the bottom of a temporary support, a steel bundle slidingly engaged with the sliding assembly, and the ends of the steel bundle respectively connected to a permanent pier structure. By applying prestressed steel bundles and horizontal steel beams passing through the temporary support structure, when the temporary support structure sinks, the prestressed steel bundles are stretched, providing the structure with a combined vertical support force. The greater the pressure on the support and the more pronounced the sinking trend, the greater the vertical support force provided by the prestressed steel bundles to the temporary support structure. At the same time, the stretching of the prestressed steel bundles will generate a horizontal force on the top of the permanent pier structure, which is detrimental to its stress. Using a horizontal steel beam passing through the temporary support structure to support the inner sides of two adjacent permanent pier structures can not only balance the horizontal tension on the left and right sides of a single pier, but also prevent damage to the cap beam or displacement of the pier due to excessive unilateral tension.

[0016] Furthermore, a steel beam is installed between the temporary support and the permanent pier structure. The steel bundle, horizontal steel beam, and temporary support structure work together to effectively limit the settlement of the temporary support structure, keeping it within a controllable range and ensuring construction quality.

[0017] Furthermore, the temporary support includes a vertical pillar 1 and a vertical pillar 2 arranged along the length direction of the steel bundle, a plurality of connecting rods 1 are arranged between the vertical pillar 1 and the vertical pillar 2, the bottom surfaces of the vertical pillar 1 and the vertical pillar 2 are both provided with the sliding assembly, and the steel bundle is slidably connected to the sliding assembly.

[0018] Furthermore, the sliding assembly includes a first and second fixed rods connected to the bottom surface, with a cylindrical connecting rod interposed between the first and second fixed rods. A hole for the cylindrical connecting rod is provided at the center of a fixed pulley, and the steel bundle surrounds the fixed pulley. A fixed pulley is provided at the bottom of the temporary support, and the prestressed steel bundle passes through the fixed pulley and exits the bottom of the support. Deformation caused by support settlement is transferred to the prestressed steel bundle via the fixed pulley. This prevents the prestressed steel bundle from direct contact with the temporary support, which could cause frictional damage to the prestressed steel bundle.

[0019] Furthermore, a circumferential surface of the fixed pulley is provided with a step for limiting the steel bundle.

[0020] Furthermore, the temporary support also includes vertical pillar three and vertical pillar four that form a quadrilateral with the vertical pillar one and the vertical pillar two, and a number of connecting rods two are arranged between the vertical pillar one, the vertical pillar two, the vertical pillar three, and the vertical pillar four. The bottom surfaces of the vertical pillar one, the vertical pillar two, the vertical pillar three, and the vertical pillar four are all provided with the sliding assembly, and two steel bundles are arranged in parallel.

[0021] Furthermore, the permanent pier structure includes a cap beam 1, an embedded part 1 is provided on the cap beam 1, and both ends of the steel bundle are connected to the embedded part 1 on both sides.

[0022] Furthermore, the permanent pier structure includes a cap beam 2, a pier column, and a pedestal 1 connected in sequence, a pad is provided between the cap beam 2 and the cross beam, an embedded part 2 is provided on the pedestal 1, and both ends of the steel bundle pass through the pad and are connected to the embedded part 2.

[0023] Furthermore, the permanent pier structure includes a second cap beam, a pier column, and a second pedestal connected in sequence, a pad is provided between the second cap beam and the cross beam, a rigging is provided on the second pedestal, and both ends of the steel bundle pass through the pad and are connected to the rigging.

[0024] Furthermore, a ballast block is provided on the outer side of the permanent pier structure, and a third embedded part is provided on the ballast block. Both ends of the steel bundle pass through the spacer block and are connected to the third embedded part.

[0025] The specific beneficial effects of the utility model include:

[0026] 1. By applying prestressed steel strands and horizontal steel beams passing through the temporary support structure, when the temporary support structure sinks, the prestressed steel strands are stretched, which will provide the structure with a net vertical support force. The greater the pressure on the support and the more obvious the sinking trend, the greater the vertical support force provided by the prestressed steel strands to the temporary support structure. At the same time, the stretching of the prestressed steel strands will generate horizontal forces on the top of the permanent pier structure, which is detrimental to its stress resistance. Using horizontal steel beams passing through the temporary support structure to support the inner sides of two adjacent permanent pier structures can not only balance the horizontal tension on the left and right sides of a single pier, but also prevent damage to the cap beam or displacement of the pier due to excessive tension on one side.

[0027] 2. The steel bundles, horizontal steel beams and temporary support structures work together to effectively limit the settlement of the temporary support structure, keeping the settlement within a controllable range and ensuring construction quality;

[0028] 3. Install a fixed pulley at the bottom of the temporary support. The prestressed steel strands pass through the fixed pulley and exit from the bottom of the support. The deformation caused by the support settlement is transferred to the deformation of the prestressed steel strands through the fixed pulley. This prevents the prestressed steel strands from direct contact with the temporary support, which could cause friction damage to the prestressed steel strands. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] Example 1, a collaborative bridge temporary support system for soft soil foundation, such as Figure 2 As shown, it includes a temporary support structure supported under the beam 1, and the temporary support structure includes a sliding component 3 arranged at the bottom of the temporary bracket 2. The steel bundle 4 slides with the sliding component 3, and the two ends of the steel bundle 4 are respectively connected to the permanent pier structure 5.

[0057] In order to avoid the need for foundation treatment, a set of prestressed steel strands 4 can be passed through the temporary support 2 and then anchored to the adjacent two permanent piers 5 and supported on the inner side of the adjacent two permanent piers 5 by a steel beam 7 passing through the temporary support 2. If the site conditions of the beam 1 are only poor in a certain span in the middle, the temporary support 2 of the span can be used. Figure 2 Single span V-shaped tendon arrangement shown.

[0058] Specifically, after the cross beam 1, temporary support 2, and steel bundle 4 are successfully installed, the beam body is pushed to make it slide along the top of the cross beam 1, and the cross beam 1 serves as a sliding track for the beam body.

[0059] On the basis of the above embodiment, a steel beam 7 is provided between the temporary support 2 and the permanent pier structure 5. Without the combined effect of this group of prestressed steel bundles 4 and the steel beam 7 passing through the temporary support 2, as the construction of the upper bridge progresses and the weight of the upper beam increases, the pressure on the temporary support 2 will continue to increase. Since the soft soil foundation below has a low stiffness, this will cause the temporary support 2 to sink significantly, and eventually cause the upper beam to sag, making it impossible to meet the construction requirements.

[0060] On the basis of the above implementation mode, Figure 3 As shown, one steel bundle 4 is provided, and the temporary support 2 includes a vertical pillar 1 21 and a vertical pillar 2 22 arranged along the length direction of the steel bundle 4.

[0065] On the basis of the above embodiment, a steel beam 7 is provided between the temporary support 2 and the permanent pier structure 5. Without the combined effect of this group of prestressed steel bundles 4 and the steel beam 7 passing through the temporary support 2, as the construction of the upper bridge progresses and the weight of the upper beam increases, the pressure on the temporary support 2 will continue to increase. Since the soft soil foundation below has a low stiffness, this will cause the temporary support to sink significantly, and eventually cause the upper beam to sag, making it impossible to meet the construction requirements.

[0066] On the basis of the above implementation mode, Figure 5 、 Figure 6 As shown, the temporary support 2 includes a vertical support 1 21 and a vertical support 2 22 arranged along the length direction of the steel bundle 4, and a plurality of connecting rods 1 23 are arranged between the vertical support 1 21 and the vertical support 2 22. The temporary support 2 also includes a vertical support 3 25 and a vertical support 4 26 forming a quadrilateral with the vertical support 1 21 and the vertical support 2 22. The vertical support 1 21, the vertical support 2 22, the vertical support 3 25, and the vertical support 4 26 are all connected.
