[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 5 As shown, a quick-detachable combined temporary bridge includes a base module, a heightening module, a support beam module and a bridge deck module, wherein the heightening module is detachably connected to the top of the base module, the support beam module is detachably connected to the top of the heightening module, and the bridge deck module is detachably connected to the top of the support beam module. A first docking structure is fixedly arranged between the base module and the heightening module, and a second docking structure is arranged between the heightening module and the support beam module. When the temporary bridge is in operation, the base module is first connected to the heightening module through the first docking structure, and then the support beam module is connected to the heightening module through the second docking structure. Finally, the bridge deck module is laid on the support beam module to realize the assembly of the temporary bridge, and the temporary bridge is divided into several separate modules to make its assembly simple and fast. The base module here is only used in the area located in the river channel, and the shore area of ​​the temporary bridge is not considered here. When dismantling a temporary bridge, the bridge deck module, support beam module, and heightening module are removed in sequence. The height of the top of the heightening module exceeds the water surface in the non-rainstorm season. After the heightening module is removed in the rainstorm season, the base module is at a lower height in the water, and the impact on its root when impacted by the water flow is relatively small, which is conducive to the stability of the entire base module. By separating the base module from the heightening module, the height requirement of the bridge deck in the non-rainstorm season can be guaranteed, and the impact force of the water flow on the temporary bridge base can be reduced in the rainstorm season.

[0032] The base module includes two groups of pile foundation columns 1 which are parallel to each other and distributed in a linear array. The pile foundation column 1 includes an underground section 101 and an above-ground section 102. When in operation, the underground section 101 of the pile foundation column 1 is buried in a deeper position in the river channel during initial construction, and the above-ground section 102 is used to dock with the heightening module.

[0033] The heightening module includes a plurality of heightening columns 2, and the heightening columns 2 are fixedly arranged on the top of the fixed ground section 102; the first docking structure includes a limiting groove 3 and a limiting pin 4 that cooperate with each other, and the limiting groove 3 is opened on the top of the pile foundation column 1, and the limiting pin 4 is fixedly arranged at the bottom of the heightening column 2; when working, when assembling the heightening column 2 and the pile foundation column 1, it is only necessary to lift the heightening column 2 to align the limiting groove 3 with the limiting pin 4, and then put down the heightening column 2 to achieve installation. It should be noted that if Figure 3 As shown, the limiting groove 3 here includes a tapered groove 301 and a positioning groove 302. The tapered groove 301 is convenient for docking with the limiting pin 4. The positioning groove 302 positions the limiting pin 4 in the circumferential direction, so that the heightening column 2 docks with the pile foundation column 1 at the same position each time. The specific structure of the limiting groove 3 and the limiting pin 4 here can be used here as long as it meets the functions of convenient docking and circumferential positioning. The heightening column 2 here preferably adopts a reinforced concrete structure, and can also adopt a metal part.

[0034] The support beam module includes two main support beams 5, which are respectively fixedly connected to two groups of pile foundation columns 1, and a plurality of connecting cross beams 6 are fixedly arranged between the two main support beams 5; the second docking structure includes a slot 7 and a pin 8 that cooperate with each other, the slot 7 is provided at the top of the heightening column 2, and the pin 8 is fixedly arranged at the bottom of the main support beam 5; when working, the main support beam 5 is lifted, the pin 8 at the bottom of the main support beam 5 is aligned with the slot 7 of the corresponding group of pile foundation columns 1, and then it is lowered, and the main support beam 5 can be installed. When installing the heightening column 2, since the heightening column 2 has been circumferentially positioned, all the slots 7 are in the same straight line. After the main support beam 5 is erected, the connecting cross beam 6 is installed and connected by bolts. In addition, since this temporary bridge only assembles the part on the river channel, the structure on the bank can limit the main support beam 5 in the direction of the extension of the slide slot, or directly make the end of the main support beam 5 erected against the river bank on both sides of the river channel.

[0035] The bridge deck module includes a plurality of cover plates 9, which are mounted on the top of the two main support beams 5 and fixedly connected to the main support beams 5. When working, the cover plates 9 are in an inverted U shape and are inverted on the two main support beams 5. The bottom of the cover plates 9 is in contact with the top of the main support beams 5 and the top of part of the connecting beams 6. According to actual needs, a reinforcement structure can also be set between the connecting beams 6 and the main support beams 5, and the cover plates 9 can be fixed by fixing structures such as bolts.

[0036] The cross section of the pile foundation column 1 is in the shape of a water drop, and the outer wall of the large end of the pile foundation column 1 is the water-facing surface; when working, the pile foundation column 1 is designed to be in the shape of a water drop, and its streamlined shape can reduce the impact force of water on the pile foundation column 1 when flowing.

[0037] A plurality of lifting ears 10 are fixedly provided on the outer wall of the heightening column 2 ; during operation, the lifting ears 10 are used to lift or dismantle the heightening column 2 .

[0038] The side walls of the main support beam 5 are also fixedly provided with a plurality of insert tubes 11, in which insert rods 12 are inserted, and barrier rods 13 are also provided between adjacent insert tubes 11; when working, the insert rods 12 and barrier rods 13 form the guardrail of the temporary bridge, and the barrier rods 13 can also be replaced with cables, glass plates, etc. according to actual needs.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
