Description

Technical Field

[0001] The utility model relates to the technical field of bridge demolition construction, in particular to an integrated support system for bridge jacking, moving and dropping based on SPMT modular vehicles. Background Art

[0002] At present, in the traditional application of bridge demolition based on SPMT modular vehicles, the support is only used as a support tooling. After the bridge is demolished, it needs to be re-converted to a beam dropping support for dropping. The support tooling cannot be used as a beam dropping support, and an additional set of beam dropping supports needs to be invested, and secondary conversion is required.

[0003] The existing bridge demolition supports based on SPMT modular vehicles have problems such as large material input, high cost, high safety risks, long cycle, and disadvantages in cost reduction, construction period optimization, and safety risk control during the process of secondary conversion of the support tooling to the beam dropping support. Summary of the Invention

[0004] The purpose of the utility model is to provide an integrated support system for bridge jacking, moving and dropping based on SPMT modular vehicles according to the deficiencies of the above-mentioned existing technologies. By improving the structure of the support bracket, it has both the functions of a bridge demolition support tooling and a beam dropping support, and designs the support foundation of the beam dropping support to realize the overall falling of the support under load, so as to separate the SPMT modular vehicle from the support and quickly drive away.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] An integrated support system for bridge jacking, moving and dropping based on SPMT modular vehicles, including a support bracket composed of longitudinally and transversely intersecting bottom beams, a main support steel pipe is arranged above the support bracket, and a top beam is arranged above the main support steel pipe, characterized in that: the length of the bottom beam is lengthened and extends outward, and the lengthened part is connected with the main support steel pipe through inclined braces to form an integral structure; a dropping support round pipe is arranged at the bottom end position of the lengthened part of the bottom beam.

[0007] A plurality of the main support steel pipes are uniformly arranged above the support bracket, and the main support steel pipes are connected through cross bars and diagonal bars to form an integral structure.

[0008] A dropping concrete enlarged foundation is arranged at the bottom of the dropping support round pipe.

[0009] Reinforcing ribs are arranged at the positions of the bottom beams corresponding to the dropping support round pipes.

[0010] Reinforcing ribs are arranged on the top beam.

[0011] The advantages of the present utility model are as follows: The integrated support material for demolition, transportation, and lowering has less input, low cost, good economy, no need for secondary conversion, low safety risk, short cycle, and is conducive to saving time.

[0020] The features of the present utility model and other related features are further described in detail below with reference to the drawings through embodiments for the understanding of those skilled in the same industry:

[0021] As Figure 1-8 shown, the markings 1 - 14 in the figure respectively represent: bottom beam 1, bottom beam 2, main support steel pipe 3, top beam 4, cross bar 5, cross bar 6, diagonal bar 7, diagonal bar 8, diagonal bar 9, diagonal brace 10, stiffening rib 11, stiffening rib 12, lowering support round pipe 13, and lowering concrete enlarged foundation 14.

[0022] Embodiment: As Figures 1 to 8 shown, in this embodiment, the integrated support system for bridge jacking, transportation, and lowering based on the SPMT module vehicle has both the functions of a bridge demolition support tooling and a lowering support, and designs the support foundation of the lowering support to solve the problems existing in the existing bridge demolition support based on the SPMT module vehicle, such as large material input, high cost, high safety risk during the secondary conversion of the support tooling to the lowering support, long cycle, and being not conducive to cost reduction, construction period optimization, and safety risk control.

[0023] Specifically, the system in this embodiment includes a support bracket for supporting the bridge beam body. The support bracket is composed of a bottom beam 1 and a bottom beam 2 arranged vertically and horizontally to form a frame structure. At the node positions of the frame structure composed of the bottom beam 1 and the bottom beam 2, vertically arranged main support steel pipes 3 are respectively provided. Above each main support steel pipe 3, a top beam 4 is respectively provided. The main support steel pipe 3 supports the bridge beam body from the bottom through the top beam 4.

[0024] In this embodiment, as shown in Figure 2 and Figure 3 , between each main support steel pipe 3, a horizontally arranged cross bar 5 and a cross bar 6 are provided to connect and form an integral structure. At the same time, the connection is further strengthened by diagonal bars 7 and diagonal bars 8 to enhance the stability of the support system and ensure the stability of the support lifting and transporting process.

[0025] As shown in Figure 5 and Figure 6 , the bottom beam 1 extends outward for a certain distance, exceeding the width of the SPMT module vehicle and leaving a space for the unloading support fulcrum. Below the end of the bottom beam 1, a unloading support round pipe 13 is provided. Below the unloading support round pipe 13, a unloading concrete enlarged foundation 14 is provided to realize the overall falling of the support under load, so that the SPMT module vehicle can be separated from the support and can quickly drive away.

[0026] In this embodiment, the extended part of the bottom beam 1 and the main support steel pipe 3 are strengthened and connected by a diagonal brace 10 to form an integral structure, increasing the stability of the support system. In addition, at the position of the bottom beam 1 corresponding to the unloading support steel pipe 13, a reinforcing rib 11 is provided, and a reinforcing rib 12 is provided inside the top beam 4 to enhance the joint strength.

[0027] As shown in Figure 8 , when this embodiment is implemented, it includes the following steps:

[0028] 1) The SPMT module vehicle transports the support and the structure to the designated position.

[0029] 2) After the unloading support round pipe 13 is set up, the SPMT module vehicle slowly descends through its own hydraulic system. The unloading support round pipe 13 contacts and bears the force with the bottom beam 1, and the SPMT module vehicle continues to slowly descend until the module vehicle panel is separated from the bottom beam 1, and all the support loads are transferred from the unloading support round pipe 13 to the concrete enlarged foundation 14.

[0030] 3) The SPMT module vehicle drives away and the unloading is completed.

[0031] Although the above embodiments have been described in detail with reference to the accompanying drawings for the concept and embodiments of the object of the present utility model, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present utility model without departing from the scope defined by the claims, so they will not be elaborated one by one herein.
