Description

Technical Field

[0001] This utility model relates to the field of road culvert technology, specifically a road culvert structure. Background Technology

[0002] A road culvert is an underground structure used to cross roads, rivers or other obstacles. It is usually made of precast or cast-in-place concrete and features a sturdy structure, smooth water flow, and quick construction. It is mainly used for multiple functions such as drainage, irrigation, and transportation, ensuring that water can pass smoothly without affecting the normal operation of surface traffic. It is an important part of urban infrastructure construction.

[0003] Most existing methods for constructing road culverts rely on traditional manual stacking, where each culvert is built piece by piece. This method is not only extremely slow and cannot meet the high timeliness requirements of modern engineering, but it is also prone to deviations due to human or environmental factors during the stacking process, such as errors in levelness and verticality. These deviations directly affect the stability and precision of the overall structure. Furthermore, because it is difficult to achieve complete precision during the stacking process, a large amount of repair and adjustment work is often required later. This not only increases the complexity and workload of the project, but also greatly increases the cost and difficulty of later maintenance. At the same time, the instability and insufficient precision of the structure may also cause a series of safety problems, posing a great threat to the quality and safety of the project. Utility Model Content

[0004] The purpose of this utility model is to provide a road culvert structure in order to solve the problems mentioned above.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a culvert structure, comprising: a quick assembly mechanism, the quick assembly mechanism including a top plate, a side plate hinged to the side of the top plate, an edge plate hinged to the side of the side plate, hinges fixed to the inner sides of the top plate, the side plate and the edge plate, a hydraulic support long rod hinged between the hinge of the top plate and the hinge of the side plate, a hydraulic support short rod hinged between another set of hinges of the side plate and the hinge of the edge plate, and a bottom plate placed on the side of the edge plate.

[0006] As a further embodiment of this utility model: a quick assembly mechanism is placed on the outside of the outer frame, a casting cavity is opened between the outer frame and the quick assembly mechanism, a supporting steel bar is fixedly connected inside the casting cavity, and a casting port is opened on the top of the outer frame.

[0007] As a further improvement of this utility model: a door groove is provided on the side of the outer frame, and a frame door is installed on the side of the door groove.

[0008] As a further embodiment of this utility model: there are two sets of side plates and two sets of edge plates, symmetrically arranged on both sides of the top plate; there are multiple sets of hinges; there are four sets of hydraulic support long rods and four sets of hydraulic support short rods; the bottom plate is placed in the slope opened inside the two sets of edge plates; and the closed shape formed by the top plate, the side plates, the edge plates and the bottom plate is a symmetrical polygon.

[0009] As a further improvement of this utility model, the pouring port extends through the top of the outer frame into the pouring cavity.

[0010] As a further improvement of this utility model: the door groove is adapted to the frame door, and the frame door has a symmetrical polygon with the same shape as the quick assembly mechanism, and the frame door fits snugly with the quick assembly mechanism.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention significantly improves construction speed through the construction of a cross-road box culvert structure. Traditional manual stacking methods require gradual accumulation of construction, which is tedious and time-consuming. However, this invention achieves rapid construction and stabilization of the box culvert structure through a rapid assembly mechanism that utilizes the hinged connections of components such as the top plate, side plate, and edge plate, as well as the adjustment of hydraulic support rods. This modular assembly method not only simplifies the construction process but also greatly shortens the construction cycle, improves work efficiency, and meets the high timeliness requirements of modern engineering.

[0013] Secondly, this structure can significantly reduce the occurrence of deviations during construction. Traditional stacking methods are prone to errors in horizontality and verticality due to human or environmental factors, affecting the stability and accuracy of the overall structure. However, this utility model ensures precise connection and stable support between various components through precise modular design and hydraulic support rod adjustment, effectively avoiding these deviations. This not only improves the stability and accuracy of the overall structure but also reduces the workload of later repairs and adjustments, lowering the complexity of the project and maintenance costs.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 3In this embodiment of the utility model, a culvert structure includes: a quick assembly mechanism 1, which includes a top plate 2, side plates 3 hinged to the sides of the top plate 2, and side plates 4 hinged to the sides of the side plates 3. Two sets of side plates 3 and side plates 4 are provided, symmetrically arranged on both sides of the top plate 2. Hinges 5 are fixedly connected to the inner sides of the top plate 2, side plates 3, and side plates 4, and multiple sets of hinges 5 are provided. A hydraulic support rod 6 is hinged between the hinges 5 of the top plate 2 and the hinges 5 of the side plates 3, and a hydraulic support rod 7 is hinged between the other set of hinges 5 of the side plates 3 and the hinges 5 of the side plates 4. After the outer frame 9 is assembled, the quick assembly mechanism 1 is placed inside the outer frame 9 according to the design requirements. The quick assembly mechanism 1 consists of components such as top plate 2, side plate 3, and edge plate 4. It is quickly assembled and stabilized through hinges 5, hydraulic support long rods 6 and hydraulic support short rods 7. When placing the quick assembly mechanism 1, it is necessary to ensure that its position is accurate and matches the internal space of the outer frame 9 so as to form a complete casting cavity 10. There are four sets of hydraulic support long rods 6 and hydraulic support short rods 7. The connection between the hydraulic support long rods 6 and hydraulic support short rods 7 and the hinges 5 is installed with bolts. The side plate 4 has a bottom plate 8 placed on its side. The bottom plate 8 is placed in the slope opened inside the two sets of side plates 4. The closed shape formed by the top plate 2, side plate 3, edge plate 4 and bottom plate 8 is a symmetrical polygon.

[0021] After the concrete curing is completed, the bottom plate 8 is removed. The bottom plate 8 serves as the bottom support of the box culvert structure and plays an important role in the pouring process. However, after the concrete has solidified, the bottom plate 8 can be removed to facilitate subsequent steps. After the bottom plate 8 is removed, the quick assembly mechanism 1 can be detached from the poured concrete by rotating the side plates 3 and edge plates 4 inward. Since the quick assembly mechanism 1 is connected by the hinge 5 and the hydraulic support rod, it can be easily disassembled and reused. When disassembling the quick assembly mechanism 1, it is necessary to ensure the integrity and reusability of each component so that it can be reused in future projects. Finally, the disassembled quick assembly mechanism 1 is removed from the pouring cavity 10 and cleaned and maintained. These mechanisms can be reused in future projects, reducing construction costs and time.

[0022] Reference Figure 2A quick assembly mechanism 1 is placed on the outside of the outer frame 9. According to the construction requirements and design drawings, a suitable site is selected for the construction of the outer frame 9. The outer frame 9 serves as the external frame of the entire box culvert structure, playing a supporting and protective role. When constructing the outer frame 9, it is necessary to ensure that its size and shape match the quick assembly mechanism 1 so that subsequent steps can proceed smoothly. A pouring cavity 10 is opened between the outer frame 9 and the quick assembly mechanism 1. Supporting steel bars 11 are fixed inside the pouring cavity 10. After the quick assembly mechanism 1 is placed, supporting steel bars 11 need to be placed inside the pouring cavity 10. Supporting steel bars 11 play a role in enhancing the strength and stability of concrete and preventing the concrete from deforming or cracking during the pouring process.

[0023] The quantity and arrangement of the supporting steel bars 11 need to be determined according to the design requirements to ensure the stability and load-bearing capacity of the concrete structure. A pouring port 12 is provided above the outer frame 9, which extends from the top of the outer frame 9 into the pouring cavity 10. After the frame door 14 is installed, concrete can be poured into the pouring cavity 10 through the pouring port 12. During the pouring process, the concrete needs to be continuously vibrated to ensure its density and uniformity. After the pouring is completed, the concrete needs to be cured for a period of time to ensure that it reaches the strength and stability required by the design.

[0024] Reference Figures 1 to 2 The outer frame 9 has a door groove 13 on its side, and a frame door 14 is installed on the side of the door groove 13. The door groove 13 and the frame door 14 are adapted to each other, and the frame door 14 has the same symmetrical polygon as the quick assembly mechanism 1. The frame door 14 fits snugly with the quick assembly mechanism 1. When installing the frame door 14, it is necessary to ensure that it fits tightly in the door groove 13 to prevent concrete leakage during the pouring process. After the concrete curing is completed, the frame door 14 should be removed first to allow for inspection and maintenance of the box culvert structure.

[0025] The working principle of this utility model is as follows: Based on the construction plan and design blueprint, a suitable location is selected to construct the outer frame 9, ensuring that the dimensions and shape of the outer frame 9 perfectly match the rapid assembly mechanism 1. This provides stable support and comprehensive protection for subsequent assembly and concrete pouring processes. Inside the constructed outer frame 9, following design guidelines, supporting steel bars 11 are properly arranged within the pouring cavity 10. Their quantity and arrangement must be sufficient to ensure the stability and load-bearing capacity of the concrete structure. Next, according to design requirements, the top plate 2 is precisely placed inside the outer frame 9, and its position is confirmed to be accurate. A hinge is then used... The synergistic action of chain 5 and hydraulic support rod 6 flexibly hinges side plate 3 and top plate 2, thus constructing a stable structural frame. Subsequently, on the other side of side plate 3, with the help of hinge 5 and hydraulic support rod 7, side plate 4 is properly installed in place. The bottom plate 8 is then stably placed within the pre-set sloping area inside the two sets of side plates 4, ensuring its stability and precise positioning. During this process, it is necessary to carefully check whether each component of the quick assembly mechanism 1 is firmly connected to prevent loosening or deformation during the pouring process. As needed, minor adjustments are made to the quick assembly mechanism 1 to ensure its connection with the outer frame 9. The internal space is perfectly matched. A pouring port 12 is opened at the top of the outer frame 9 to ensure smooth penetration into the pouring cavity 10. Concrete is evenly poured into the pouring cavity 10 through the pouring port 12, and continuous vibration is carried out during the pouring process to ensure the compactness and uniform distribution of the concrete. After the pouring operation is completed, the pouring port 12 is sealed in time, and the concrete is cured as necessary. During the curing period, the strength and stability of the concrete are tested regularly to ensure that it meets the design requirements. After the concrete curing period is over, the frame door 14 is removed first to allow for a comprehensive inspection of the box culvert structure. After maintenance, the base plate 8 is safely removed to prepare for subsequent steps. By rotating the side plates 3 and 4 inward, the quick assembly mechanism 1 is smoothly separated from the poured concrete. During this process, special care must be taken to protect the integrity of each component and ensure its reusability for future projects. Finally, the disassembled quick assembly mechanism 1 is carefully removed from the pouring cavity 10 and thoroughly cleaned and maintained. Any damaged or worn parts are carefully inspected and repaired to ensure its reliable operation and durability in future projects.
