Description

Technical Field

[0001] The utility model belongs to the technical field of steel corrugated pipe culverts, and particularly relates to an installation structure of a prefabricated steel corrugated pipe culvert. Background Art

[0002] The steel corrugated pipe culvert, also known as the corrugated pipe culvert, refers to the threaded corrugated pipe used for culverts buried under highways and railways. It is a circular steel structure pipe made by rolling waveform steel plates or assembling waveform steel sheets. The corrugated structure of the metal corrugated pipe culvert can make the stress of the culvert road surface reasonable, the load distribution uniform, and has a certain anti-deformation ability, which can solve the damage problem of bridge and pipe culvert concrete structures in cold regions in the north; there is no expansion joint on the road surface, improving the driving comfort; it is beneficial to improve the "step" phenomenon at the junction of the soft soil foundation structure and the embankment, improving the driving safety. The post-operation and maintenance costs of the corrugated pipe culvert are low, and the actual project cost is also lower than that of bridges and culverts with the same span.

[0003] During the installation process of the steel corrugated pipe culvert, ensuring its good sealing effect is crucial because it directly relates to the overall performance and long-term stability of the culvert. To achieve this goal, some steel corrugated pipe culverts do adopt welding as the main connection means when docking. The welding technology melts and fuses the metals at the docking joint through high temperature to form a strong metallurgical bond, thus ensuring a seamless connection and excellent sealing performance between the pipe culverts.

[0004] However, although the welding method effectively improves the overall structural strength and sealing performance of the steel corrugated pipe culvert, it also brings some drawbacks that cannot be ignored. First of all, welding makes the steel corrugated pipe culvert form an almost inseparable and firm integral structure. This structure performs well when dealing with the conventional loads in daily operation, but it is particularly inconvenient when later maintenance, inspection, component replacement or adaptive adjustment according to engineering changes are required. Due to the existence of the welded joints, disassembly and reassembly become complex and time-consuming, and even may require destructive demolition of the entire structure, which undoubtedly increases the maintenance cost and difficulty.

[0005] In order to balance the sealing effect and the convenience of later maintenance, this design scheme specially provides an installation structure of a prefabricated steel corrugated pipe culvert. Content of the Utility Model

[0006] The purpose of the present utility model is to provide an assembled installation structure for a steel corrugated pipe culvert, aiming to solve the problem that although the welding method effectively improves the overall structural strength and sealing performance of the steel corrugated pipe culvert, it also brings some drawbacks that cannot be ignored. First of all, welding makes the steel corrugated pipe culvert form an almost inseparable and firm integral structure. This structure performs well in dealing with the regular loads during daily operation, but it becomes particularly inconvenient when later maintenance, inspection, component replacement or adaptive adjustment according to engineering changes are required. Due to the existence of welding joints, disassembly and reassembly become complex and time-consuming, and even destructive demolition of the entire structure may be required, which undoubtedly increases the maintenance cost and difficulty.

[0007] To achieve the above purpose, the present utility model provides the following technical solutions: an assembled installation structure for a steel corrugated pipe culvert, including a steel corrugated pipe culvert, one end of the steel corrugated pipe culvert is fixedly installed with a first docking head, and a fixing ring is fixedly installed on the outer wall of the first docking head close to the connection end with the steel corrugated pipe culvert;

[0008] A sealing ring is sleeved on the outer wall of the first docking head on one side of the fixing ring. The other end of the steel corrugated pipe culvert away from the first docking head is fixedly installed with a second docking head, and a docking ring is fixedly installed on the outer wall of the end of the second docking head away from the connection end with the steel corrugated pipe culvert. Two steel corrugated pipe culverts are docked through the corresponding first docking head and second docking head.

[0009] In order to dock two steel corrugated pipe culverts, as an optimal choice for the assembled installation structure of the steel corrugated pipe culvert of the present utility model, six first threaded sleeves are fixedly installed at equal intervals on the outer wall of the fixing ring, and six second threaded sleeves are fixedly installed at equal intervals on the outer wall of the docking ring. A bolt is threadedly connected to one side of the second threaded sleeve. When the two steel corrugated pipe culverts are docked, the bolt will pass through the second threaded sleeve and be threadedly connected to the first threaded sleeve.

[0010] In order to dock the first docking head and the second docking head on two steel corrugated pipe culverts, as an optimal choice for the assembled installation structure of the steel corrugated pipe culvert of the present utility model, an inwards recessed opening is formed on the inner wall of the docking end of the second docking head and the docking ring. The inner diameter size of the inwards recessed opening is adapted to the maximum diameter size of the first docking head, and the depth of the inwards recessed opening is greater than the height of the first docking head.

[0011] In order to keep the docking ends of two steel corrugated pipe culverts sealed, as an optimal choice for the assembled installation structure of the steel corrugated pipe culvert of the present utility model, when the bolt is connected between the second threaded sleeve and the first threaded sleeve, a sealing structure is formed among the first docking head, the fixing ring, the sealing ring, the second docking head and the docking ring.

[0012] Compared with the prior art, the beneficial effects of the present utility model are:

[0013] When docking two steel corrugated pipe culverts, insert the first docking head and the second docking head of the two steel corrugated pipe culverts. At the same time, align the first threaded sleeve and the second threaded sleeve, and then pass the bolt through the corresponding first threaded sleeve and the second threaded sleeve and tighten it. In this way, the two steel corrugated pipe culverts can complete the docking in a sealed structure through this structure. In actual use, the connection method between the two steel corrugated pipe culverts can be simplified through this structure. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , the present invention provides the following technical solutions: An assembled steel corrugated pipe culvert installation structure includes a steel corrugated pipe culvert 1, and a first docking head 2 is fixedly installed at one end of the steel corrugated pipe culvert 1. A fixed ring 3 is fixedly installed on the outer wall of the first docking head 2 close to the connection end with the steel corrugated pipe culvert 1;

[0022] A sealing ring 4 is sleeved on the outer wall of the first docking head 2 on one side of the fixed ring 3. A second docking head 5 is fixedly installed at one end of the steel corrugated pipe culvert 1 away from the first docking head 2. A docking ring 6 is fixedly installed on the outer wall of one end of the second docking head 5 away from the connection end with the steel corrugated pipe culvert 1. Two steel corrugated pipe culverts 1 are docked through the corresponding first docking head 2 and second docking head 5.

[0023] Preferably: Six first threaded sleeves 301 are fixedly installed at equal intervals on the outer wall of the fixed ring 3, and six second threaded sleeves 601 are fixedly installed at equal intervals on the outer wall of the docking ring 6. A bolt 602 is threadedly connected to one side of the second threaded sleeve 601. When the two steel corrugated pipe culverts 1 are docked, the bolt 602 will pass through the second threaded sleeve 601 and be threadedly connected to the first threaded sleeve 301.

[0024] During specific use, when docking the two steel corrugated pipe culverts 1, insert the first docking head 2 and the second docking head 5 of the two steel corrugated pipe culverts 1. After the first docking head 2 and the second docking head 5 are docked, adjust the relative position between the first docking head 2 and the second docking head 5 so that each first threaded sleeve 301 and the second threaded sleeve 601 are aligned. Then pass the bolt 602 through the second threaded sleeve 601 and the first threaded sleeve 301 for docking, and tighten the bolt 602. At this time, the docking ring 6 will gradually press against the outer wall of the sealing ring 4. When the bolt 602 is completely tightened, the first docking head 2 and the second docking head 5 are also completed with docking. In this way, the two steel corrugated pipe culverts 1 can be docked together.

[0025] Preferably: An indentation 501 is formed on the inner wall of the docking end of the second docking head 5 and the docking ring 6. The inner diameter size of the indentation 501 is adapted to the maximum diameter size of the first docking head 2, and the depth of the indentation 501 is greater than the height of the first docking head 2.

[0026] During specific use, when the first docking head 2 is docked with the second docking head 5, one end of the first docking head 2 will be inserted into the indentation 501, so that the first docking head 2 and the second docking head 5 will be initially docked together.

[0027] Preferably: When the bolt 602 is connected between the second threaded sleeve 601 and the first threaded sleeve 301, a sealing structure is formed among the first docking head 2, the fixed ring 3, the sealing ring 4, the second docking head 5 and the docking ring 6.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
