[0001] This utility model relates to a support device for municipal road and bridge engineering, belonging to the field of municipal engineering technology. Background Technology

[0002] Municipal infrastructure projects refer to civil engineering, pipeline, and equipment installation projects for urban roads, public transportation, etc. Bridge construction is also a type of municipal engineering. Foundation engineering plays an extremely important role in the construction of elevated roads and bridges. It has a great impact on the safe use of the structure and the project cost. Foundation engineering basically requires pit support. Pit support is a temporary support, reinforcement, protection, and groundwater control measure adopted for the pit to protect the construction of the underground main structure and the safety of the surrounding environment.

[0003] The existing foundation pit support devices used in bridge engineering and elevated road engineering have relatively simple structures and can only support a limited depth of foundation pit. Because they cannot be adjusted, they are not convenient to use for support according to different foundation pit depths, which leads to the collapse of the foundation pit wall and has low practicality.

[0004] Therefore, there is an urgent need to improve the support device for municipal roads and bridges to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a support device for municipal road and bridge engineering. By adjusting the structure, the support height of the first support plate can be adjusted, thereby facilitating the support of foundation pits in bridge engineering and elevated road engineering of different depths, effectively preventing the collapse of the foundation pit wall and improving its practicality.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown in the figure, this embodiment provides a support device for municipal road and bridge engineering.

[0025] A support device for municipal road and bridge engineering includes a base 1, a first support plate 2 fixedly installed on one side of the base 1, an adjustment structure 3 provided on the first support plate 2, the adjustment structure 3 including a plurality of second support plates 5 movably installed on both sides of the first support plate 2 via a rotating shaft 4, a plurality of first fixing blocks 6 fixedly installed on the first support plate 2, a first bolt 7 installed on the first fixing blocks 6, and a plurality of first limiting blocks 8 fixedly installed on the second support plates 5;

[0026] Furthermore, multiple second fixing blocks 9 are fixedly installed on the surface of the first support plate 2, and second bolts 10 are installed on the second fixing blocks 9. Multiple second limiting blocks 11 are fixedly installed on the surface of the second support plate 5. Anti-detachment blocks 12 are fixedly installed on the first bolt 7 and the second bolt 10. Multiple first grooves 13 are opened at the bottom of the base 1. Hydraulic rods 14 are fixedly installed inside the first grooves 13. Multiple support plates 15 connected to the hydraulic rods 14 are provided below the base 1.

[0027] By adjusting the structure 3, the support height of the first support plate 2 can be adjusted. The second support plates 5, which are movably mounted on both sides of the first support plate 2 via the pivot 4, are flipped so that the two second support plates 5 stand upright on top of the first support plate 2. Then, the second support plates 5 are fixed by rotating the first bolt 7 to connect with the first limiting block 8. After fixing the second support plates 5 upright on top of the first support plate 2, the support height of the first support plate 2 is increased accordingly. This allows it to easily support foundation pits of varying depths in bridge engineering and elevated road engineering, effectively preventing pit wall collapse and improving practicality. After the second support plates 5 are flipped and reset, the rotation... The second bolt 10 is moved so that one end is connected to the second limiting block 11, which can also fix the reset second support plate 5 to prevent it from shaking. After the anti-detachment block 12 is set on the first bolt 7 and the second bolt 10, the first bolt 7 and the second bolt 10 can always be set on the first fixing block 6 and the second fixing block 9, effectively preventing them from falling off and being lost. Since the bottom of the foundation pit is not flat enough, the output ends of multiple hydraulic rods 14 are extended and retracted to drive different support plates 15 to adjust their height, so that multiple support plates 15 contact the bottom of the foundation pit used in bridge engineering and elevated road engineering to support the base 1 and keep it balanced, effectively improving the stability of the foundation pit support.

[0028] Furthermore, multiple fixing plates 16 are fixedly installed on both sides of the base 1. Screws 17 are installed on the fixing plates 16. Drill rods 18 are fixedly installed at the bottom of the screws 17. Multiple support frames 19 are fixedly installed between the base 1 and the first support plate 2. Reinforcing ribs 20 are fixedly installed inside the support frames 19. A second groove 21 is opened on the top of the support frame 19. A first support rod 22 connected by a damping bearing is installed inside the second groove 21. A first threaded block 23 is fixedly installed on one end of the first support rod 22. A threaded cylinder 24 is installed on the first threaded block 23. A third groove 25 is opened on one side of the second support plate 5. A second support rod 26 connected by a damping bearing is installed inside the third groove 25. A second threaded block 27 is fixedly installed on one end of the second support rod 26.

[0029] After the base 1 is stably supported, holes are drilled on both sides towards the bottom of the pit. Then, the screw 17 is rotated to descend along the thread between it and the fixing plate 16, and drilled into the hole by the drill rod 18. This makes the multiple screws 17 tightly connected to the bottom of the pit, further improving the stability of the base 1. Multiple support frames 19 and reinforcing ribs 20 are set between the base 1 and the first support plate 2, which can increase the structural strength between the base 1 and the first support plate 2 and prevent the first support plate 2 from tilting and breaking. Similarly, after the second support plate 5 is flipped and adjusted, the first support rod 22 is flipped out from the second groove 21, and then the second support rod 26 is flipped out from the third groove 25. Then, the first support rod 22 and the second support rod 26 are aligned. The threaded cylinder 24 is rotated to move on the first threaded block 23 and connect with the second threaded block 27. The first support rod 22 and the second support rod 26 are fixed by the threaded cylinder 24 connecting the first threaded block 23 and the second threaded block 27, which also improves the support strength of the second support plate 5.

[0030] In this embodiment, as Figures 1-5 As shown in the figure, the working process of a support device for municipal road and bridge engineering provided in this embodiment is as follows:

[0031] When supporting bridges and elevated roads, the base 1 is first placed on the bottom of the foundation pit, and the first support plate 2 is pressed tightly against the pit wall. Then, multiple hydraulic rods 14 are moved to extend and retract their output ends, thereby raising and lowering different support plates 15 to adjust their height. This allows the support plates 15 to contact the bottom of the foundation pit, supporting the base 1 and maintaining its balance. After the base 1 is stably supported, holes are drilled into the bottom of the pit on both sides. Then, the screw 17 is rotated to descend along the thread between it and the fixed plate 16, and the drill rod 18 is used to drill into the holes, thus... Multiple screws 17 are tightly connected to the bottom of the foundation pit, further enhancing the stability of the base 1 support. The second support plates 5, which are movably set on both sides of the first support plate 2 through the rotating shaft 4, are flipped so that the two second support plates 5 are erected on top of the first support plate 2. Then, the second support plates 5 are fixed by rotating the first bolt 7 and connecting it to the first limiting block 8. After the second support plates 5 are fixed and erected on top of the first support plate 2, the support height of the first support plate 2 is increased in sequence, so that it can be used to support foundation pits of different depths in bridge engineering and elevated road engineering, thereby effectively preventing the collapse of the foundation pit wall.
