Description

Technical Field

[0001] This utility model relates to the field of temporary bridge deck construction technology, specifically a temporary bridge deck for water conservancy projects. Background Technology

[0002] Temporary bridge decks are an emergency measure used in urgent situations or specific construction scenarios to quickly construct temporary passageways for personnel and vehicles. Water conservancy projects often involve large construction sites; temporary bridge decks can be erected over obstacles such as rivers, ditches, and foundation pits to connect various dispersed construction areas, enabling construction personnel, materials, and equipment to move quickly and conveniently between different areas, thus improving construction efficiency.

[0003] Temporary bridge decks are needed in water conservancy projects. Chinese utility model patent CN213772898U discloses a temporary bridge deck for water conservancy projects, relating to the field of water conservancy engineering technology. It includes a float, an adjusting rod at the top of the float, a hollow sleeve fitted onto the outer surface of the adjusting rod, a fixing plate at the top of the hollow sleeve, and a slot at the top of the fixing plate. The slot has teeth on both sides, and the outer surfaces of the teeth engage with a locking shaft. Support rods are located at both ends of the locking shaft, with a fixed seat at the end of the support rod furthest from the locking shaft. A strong magnetic support rod retainer is slidably connected to the outside of the slot. A pulling block is located on one side of the retainer near the first fixing plate, and a pushing block is located on the other side. The pushing block and the step below it form an automatic reset groove. A bridge deck is fixedly connected to the top of the slot, and the bridge decks are interconnected via a connecting device. This utility model effectively solves the problems of bridge deck instability, inconvenience in transportation, installation, and disassembly by setting up a float, adjusting rod, slot device, and bridge deck.

[0004] However, during the use of this utility model, due to the complex environment on the water surface, the use of floats will cause the bottom of the entire temporary bridge deck to be unstable, which will easily lead to shaking and collapse, affecting the safety of the construction site and failing to meet production needs. Therefore, a temporary bridge deck for water conservancy projects is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a temporary bridge deck for water conservancy projects, which has the advantage of high support stability. It solves the problem that the use of floats in existing temporary bridge decks leads to instability at the bottom of the entire temporary bridge deck, which can easily cause shaking and collapse, affecting the safety of the construction site and failing to meet production needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a temporary bridge deck for water conservancy projects, comprising a support column and a top plate fixedly connected to the top of the support column, wherein the support column is provided with a support and reinforcement structure extending to its bottom.

[0007] The support and reinforcement structure includes a fixed sleeve fixedly connected to the outside of the support column. A first hinge is fixedly connected to the outside of the fixed sleeve. A support rod extending to the bottom of the support column is hinged inside the first hinge. A movable sleeve is slidably connected to the outside of the support column. A second hinge is fixedly connected to the opposite side of the movable sleeve and the support rod. A hinge rod is hinged between the two second hinges.

[0008] Furthermore, there are three of each of the first hinge and the three support rods, which are evenly distributed on the outside of the support column. The end of each support rod away from the fixed sleeve is threaded with a soil-inserting nail.

[0009] Furthermore, a slider extending into the interior of the support column is fixedly connected to the inner wall of the movable sleeve, and a groove adapted to the slider is provided on the outer wall of the support column.

[0010] Furthermore, a threaded rod is rotatably connected inside the support column, and a movable seat is threadedly connected to the outside of the threaded rod. A drive motor capable of driving the threaded rod is fixedly installed inside the support column.

[0011] Furthermore, a movable sleeve is slidably connected to the outside of the supporting column, a bridge panel is rotatably connected to one side of the top plate, and a third hinge is fixedly connected to the opposite side of the bridge panel and the movable sleeve, with a connecting rod hinged between the two third hinges.

[0012] Furthermore, a limiting block is fixedly connected between the movable seat and the movable sleeve, and a limiting groove adapted to the limiting block is provided inside the supporting column.

[0013] Furthermore, there are two bridge panels, which are symmetrically distributed on the left and right sides of the top plate, and the upper surface of the bridge panels is on the same horizontal plane as the upper surface of the top plate.

[0014] Furthermore, an extension plate is provided on the side of the bridge deck away from the top plate, and a positioning block is fixedly connected to the opposite side of the extension plate and the bridge deck. A positioning groove adapted to the positioning block is opened on the opposite side of the extension plate and the bridge deck. A fixing bolt penetrating the positioning block is threadedly connected to the front of the bridge deck.

[0015] Compared with the prior art, this utility model provides a temporary bridge deck for water conservancy projects, which has the following beneficial effects:

[0016] 1. The water conservancy project uses temporary bridge decks. By setting up a first hinge and support rod, the support rod can be rotated. Then, by setting up soil nails, the support rod can be fixed to the ground. At the same time, in conjunction with the support column, the entire device can be kept in a stable state. By setting up a second hinge and hinge rod, the support rod can be reinforced without affecting the storage of the support rod, further improving the overall stability and preventing swaying.

[0017] 2. The temporary bridge deck used in this water conservancy project is equipped with a drive motor that rotates a threaded rod, which in turn moves a movable seat. This allows for the lifting and lowering of the movable sleeve, which in turn supports and expands the bridge deck. This facilitates the temporary construction of the bridge deck by workers, improves work efficiency, and solves the problem that the use of floats in existing temporary bridge decks leads to instability at the bottom of the entire temporary bridge deck, which can easily cause shaking and collapse, affecting the safety of the construction site and failing to meet production needs.
