Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a simple construction bridge used for water conservancy construction. Background Art

[0002] In the construction of water conservancy projects, such as dams, sluice gates, and pumping stations, the construction site is relatively large. Construction bridges provide construction workers with a passage across rivers, channels, or other water obstacles, facilitating their quick and safe passage between different construction areas. For example, when carrying out slope protection construction on both sides of a wider irrigation channel, construction workers can use the construction bridge to travel back and forth between the two sides of the channel without having to detour to find shallows or other ways to cross the river.

[0003] After searching, the applicant found that a Chinese patent disclosed "a simple construction bridge for water conservancy construction", and its publication (announcement) number is "CN 219385981 U". The patent mainly includes two supporting piles and pile nails. The inner sides of the supporting piles are provided with installation slots, and bridge plates are clamped in the installation slots. The bridge plates are clamped through the installation slots for preliminary fixation, and further fixed by reinforcement nails. Further fixation is performed by the cooperation of support rods and support plates, thereby increasing the overall stability during installation. However, the bridge plates in the above-mentioned prior art are flat and relatively weak in stability. If strong winds occur, the flat bridge plates cannot disperse the lateral force, and the wind load will directly act on the surface of the bridge plates, resulting in a decrease in stability. For this reason, we propose a simple construction bridge for water conservancy construction. Utility Model Content

[0004] The purpose of the present utility model is to provide a simple construction bridge for water conservancy construction, so as to solve the problem raised in the above-mentioned background technology that the bridge deck in the above-mentioned prior art adopts a flat surface and has relatively weak stability. If strong winds occur, the flat bridge deck cannot disperse the lateral force, and the wind load will directly act on the surface of the bridge deck, resulting in a decrease in stability.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a simple construction bridge for water conservancy construction, comprising a fixing device and a bridge deck stabilizing device, the fixing device comprising four groups of fixing columns, a base and a counterweight chassis, the bridge deck stabilizing device comprising a stabilizing block and a curved bridge plate, the stabilizing block being provided in four groups and being sleeved on the surfaces of the four groups of fixing columns, the stabilizing block being connected to a support rod through a supporting beam plate, the two sides of the curved bridge plate being fixedly connected with a fixing plate, and the surface of the curved bridge plate being provided with an anti-slip strip.

[0006] As a preferred solution, a first threaded hole is formed through the surface of the stabilizing block and the fixing column, and a second bolt is threadedly connected to the inner surface of the first threaded hole. Two groups of support beam plates are provided, and the two ends of the two groups of support beam plates are respectively fixedly connected to the surfaces of the four groups of stabilizing blocks. Multiple groups of metal plates are provided between the two groups of support beam plates at equal distances.

[0007] As a preferred solution, the support rods are provided in two groups and are fixedly installed on the surfaces of the two groups of support beam plates, and their top ends are fixedly installed on the bottom of the arc-shaped bridge plate, and the bottoms of both ends of the fixed plate are fixedly connected to the surface of the stabilizing block.

[0008] As a preferred solution, guardrails are fixedly installed on the surfaces of the two groups of supporting beams and on both sides of the curved bridge deck.

[0009] As a preferred solution, the fixed column is fixedly installed on the surface of the base, a pointed rod is fixedly installed at the bottom axis of the base and passes through the counterweight chassis, the bottom of the base is hinged with a plurality of connecting plates distributed in a circular array, the end of the connecting plate away from the base is fixedly connected to a second fixed block, the circumferential surface of the counterweight chassis is fixedly installed with a plurality of first fixed blocks distributed in a circular array, and the bottom of the counterweight chassis is fixedly installed with a plurality of conical rods distributed in a circular array.

[0010] As a preferred solution, a second threaded hole is formed through the axis of the first fixing block and the second fixing block, and a first bolt is threadedly connected to the second threaded hole. The circumferential surfaces of the multiple groups of tapered rods are fixed with barbs.

[0011] The technical effects and advantages of this utility model are:

[0012] 1. By installing a bridge deck stabilization device, first use the second bolt to firmly fix the stabilization block to the surface of the fixed column, then use positioning screws to fix multiple metal plates between the supporting beams to form a stable whole. Then, support rods are installed between the supporting beams and the curved bridge deck to provide solid and strong support for the curved bridge deck. The curved bridge deck adopts a unique curved structure with excellent mechanical properties. It can distribute the load more evenly to the various supporting structures of the bridge. Its force-bearing method perfectly matches the principle of force decomposition and transmission. Moreover, the curved structure itself has natural stability. When carrying weight, it will generate horizontal thrust. This thrust is exquisitely balanced between the foundation of the bridge and various fixing devices, thereby greatly enhancing the bridge's anti-overturning ability and making the entire bridge show extremely strong stability.

[0013] 2. By setting up a fixing device, first, excavate the pile foundation on the ground on both sides of the ditch, then place the lower half of the fixing column in the soil pile foundation, and then use external force to hit the fixing column. During the hitting process, the pointed rod and multiple tapered rods on the fixing column will be inserted into the inner bottom surface of the soil pile foundation until the counterweight chassis is tightly fitted with the inner bottom surface of the soil pile foundation. The counterweight chassis has the characteristics of large contact area and heavy weight, which enables it to provide extremely stable support for the entire fixing device, and barbs are provided on the surface of the tapered rod. When the tapered rod is inserted into the inner bottom surface of the soil pile foundation, these barbs will be in close contact with the soil particles. The presence of the barbs changes the contact mode between the tapered rod and the soil, effectively increases the contact area, and further enhances the stability of the entire device after installation. Finally, inject soil into the soil pile foundation to complete the installation of the fixing device. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] 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 making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] Please see the attached Figure 1 - Attachment Figure 3 A simple construction bridge for water conservancy construction includes a fixing device 1 and a bridge deck stabilizing device 2. The fixing device 1 includes four groups of fixing columns 11, a base 12 and a counterweight chassis 14. The bridge deck stabilizing device 2 includes a stabilizing block 201 and an arc-shaped bridge plate 204. The stabilizing block 201 is provided with four groups and is sleeved on the surface of the four groups of fixing columns 11. The stabilizing block 201 is connected to a support rod 203 through a supporting beam plate 202. The two sides of the arc-shaped bridge plate 204 are fixedly connected with a fixing plate 205. The surface of the arc-shaped bridge plate 204 is provided with an anti-slip strip 206. The stabilizing block 201 and the fixing column 1 1 is penetrated by a first threaded hole, and a second bolt 208 is threadedly connected in the first threaded hole. Two groups of support beam plates 202 are provided, and the two ends of the two groups of support beam plates 202 are fixedly connected to the surfaces of the four groups of stabilizing blocks 201 respectively. A plurality of groups of metal plates 207 distributed at equal distances are provided between the two groups of support beam plates 202. Two groups of support rods 203 are provided and are fixedly installed on the surfaces of the two groups of support beam plates 202 respectively, and their top ends are fixedly installed on the bottom of the arc-shaped bridge plate 204. The bottoms of both ends of the fixing plate 205 are fixedly connected to the surface of the stabilizing block 201.

[0023] From a maintenance perspective, the drainage performance of the curved bridge deck 204 is generally better than that of a flat bridge deck. Due to its own curvature, rainwater, construction water, etc. can flow away from the bridge deck more quickly, reducing the erosion of the bridge deck material by water accumulation on the bridge deck. For concrete bridge decks, accumulated water may cause the steel bars in the concrete to rust, thereby affecting the service life of the bridge deck. The curved bridge deck 204 can effectively avoid this situation, allowing the bridge deck material to maintain better performance and extend the service life of the construction bridge. The support beam plate 202 and the metal plate 207 are fixed by positioning screws, and the installation is stable and easy to disassemble.

[0024] Specifically, the stabilizing block 201 is fixed to the surface of the fixing column 11 by the second bolt 208, and the plurality of metal plates 207 are fixed between the supporting beam plates 202 using positioning screws. The support rod 203 is installed between the supporting beam plates 202 and the curved bridge plate 204 to provide stable support for the curved bridge plate 204. The curved bridge plate 204 adopts an arc structure to distribute the load more evenly to the supporting structure of the bridge. The force mode of the curved bridge plate 204 conforms to the principle of force decomposition and transmission. The arc structure has natural stability and can generate horizontal thrust. These thrusts are balanced with each other between the foundation of the bridge and the fixing device 1, thereby increasing the anti-overturning ability of the bridge, having extremely strong stability and not prone to water accumulation.

[0025] Example 2:

[0026] Please see the attached Figure 1 - Attachment Figure 2 , and attached Figure 4- Attachment Figure 5 , and on the basis of Example 1, it is further obtained that guardrails 3 are fixedly installed on the surfaces of the two groups of supporting beams 202 and on both sides of the arc-shaped bridge plate 204, the fixing columns 11 are fixedly installed on the surface of the base 12, and a pointed rod 13 is fixedly installed at the bottom axis of the base 12 and passes through the counterweight chassis 14, the bottom of the base 12 is hinged with a plurality of connecting plates 15 distributed in a circular array, and the end of the connecting plate 15 away from the base 12 is fixedly connected to a second fixed block 17, and a plurality of first fixed blocks 16 distributed in a circular array are fixedly installed on the circumferential surface of the counterweight chassis 14, and a plurality of conical rods 18 distributed in a circumferential array are fixedly installed on the bottom of the counterweight chassis 14, and a second threaded hole is penetrated at the axis of the first fixing block 16 and the second fixing block 17, and a first bolt 19 is threadedly connected in the second threaded hole, and the circumferential surface of the plurality of groups of conical rods 18 are fixedly installed with barbs.

[0027] The setting of the guardrail 3 effectively improves the safety of workers walking on the bridge deck and prevents them from falling from the bridge deck. The base 12 and the counterweight chassis 14 are fixed by the first bolt 19, which is convenient for installation and disassembly. During disassembly, the first bolt 19 is removed and the fixing column 11, base 12 and pointed rod 13 can be pulled out. The counterweight chassis 14 buried underground can be reserved here or taken out by external tools for easy disassembly.

[0028] Specifically, first, soil pile foundations are dug on the bottom surfaces of both sides of the ditch, and the lower half of the fixing column 11 is placed in the soil pile foundation. Then, the fixing column 11 is hit by external force, so that the pointed rod 13 and multiple tapered rods 18 are inserted into the inner bottom surface of the soil pile foundation, and the counterweight chassis 14 fits with the inner bottom surface of the soil pile foundation. The counterweight chassis 14 has the advantages of large contact area and large weight, providing stable support for the entire fixing device 1. The barbs on the surface of the tapered rod 18 will be in close contact with soil particles. The presence of the barbs changes the contact mode between the tapered rod 18 and the soil, increases the contact area, and further improves the installation stability. Then, soil is injected into the soil pile foundation to complete the installation of the fixing device 1.

[0029] Working principle of the utility model: The utility model is a simple construction bridge for water conservancy construction. First, the soil pile foundation is dug on the bottom surface of both sides of the ditch, and the lower half of the fixing column 11 is placed in the soil pile foundation. Then, the fixing column 11 is hit by an external force, so that the pointed rod 13 and multiple tapered rods 18 are inserted into the inner bottom surface of the soil pile foundation. The counterweight chassis 14 fits with the inner bottom surface of the soil pile foundation. The counterweight chassis 14 has the advantages of large contact area and large weight, which provides stable support for the entire fixing device 1. The barbs on the surface of the tapered rod 18 will be in close contact with the soil particles, improving the installation stability. Then, soil is injected into the soil pile foundation to complete the installation of the fixing device 1. Subsequently, the second bolt 20 8. Fix the stabilizing block 201 on the surface of the fixed column 11, use positioning screws to fix multiple metal plates 207 between the supporting beam plates 202, and install support rods 203 between the supporting beam plates 202 and the curved bridge plates 204 to provide stable support for the curved bridge plates 204. The curved bridge plates 204 adopt an arc-shaped structure to distribute the load more evenly to the supporting structure of the bridge. The force bearing method of the curved bridge plates 204 conforms to the principle of force decomposition and transmission. The arc-shaped structure has natural stability and can generate horizontal thrust. These thrusts are balanced with each other between the foundation of the bridge and the fixing device 1, thereby increasing the bridge's anti-overturning ability. The construction of the bridge is completed, and the entire process is completed.
