Description

Technical Field

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

[0002] In highway construction, culverts play an irreplaceable role as important drainage and traffic structures. Traditional highway culvert construction methods mostly adopt on-site casting. Although this method can ensure the integrity of the structure, it has problems such as long construction period, great influence of environmental factors, and difficulty in precise quality control. Especially in some areas with complex terrain and limited construction conditions, traditional construction methods face many challenges. With the development of industrialized building, prefabricated building structures have gradually emerged and been applied to the field of highway culverts. Prefabricated highway culvert segmental structures, through factory prefabrication and on-site assembly, have significantly shortened the construction period, improved construction efficiency, and reduced environmental pollution and resource waste caused by on-site construction.

[0003] However, existing prefabricated highway culvert segment structures usually lack drainage structures. When water accumulates on the road surface, it tends to pool at the top of the culvert segments. If this water remains at the top of the segments for an extended period, it can easily seep into the culvert through the gaps at the joints, causing leaks and inconvenience to users. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated highway culvert segment structure to solve the problem in the prior art where water accumulates at the top of the culvert segment for a long time, which easily causes water to seep into the culvert through the gaps at the joints, resulting in water leakage inside the culvert and causing a lot of inconvenience to users.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated highway culvert segment structure, comprising:

[0006] The culvert segment mechanism and the splicing block mechanism assembled on one side of the culvert segment mechanism, and the splicing groove mechanism assembled on the other side of the culvert segment mechanism;

[0007] The culvert segment mechanism includes a segment body, and a drainage channel is provided inside the segment body near the top.

[0008] The splicing block mechanism includes a sealing ring seat connected to one side of the segment body. The sealing ring seat has a docking hole inside that corresponds to the drainage channel, and a guide hole communicating with the docking hole is opened on the top of the sealing ring seat.

[0009] The splicing groove mechanism includes an outer limiting ring and an inner limiting ring respectively installed on the other side of the segment body. The sealing ring seat is inserted between the outer limiting ring and the inner limiting ring. The top of the outer limiting ring is provided with a flow-guiding groove, and the bottom of the flow-guiding groove is provided with a through hole corresponding to the flow-guiding hole.

[0010] Furthermore, operating cavities are provided at the four corners of the inner wall of the segment, and fixing holes are provided on the inner wall of the operating cavity.

[0011] Furthermore, mounting bases are fixedly installed on both sides of the segment body, and mounting holes are formed on the surface of the mounting bases.

[0012] Furthermore, an outer sealing ring is inlaid and installed around the outer sealing ring seat, and a second sealing groove corresponding to the outer sealing ring is opened on the inner wall of the outer limiting ring.

[0013] Furthermore, an inner sealing ring is embedded in the inner wall of the sealing ring seat, and a first sealing groove corresponding to the inner sealing ring is opened on the outer periphery of the inner limiting ring.

[0014] Furthermore, a guide slope is provided on one side of the outer limiting ring and the inner limiting ring, and a sealing ring corresponding to the guide slope is installed on the outer periphery and inner wall of the sealing ring seat.

[0015] Furthermore, a support frame is fixedly installed on the inner wall of the drainage channel, and a filter plate is placed on top of the support frame.

[0016] Compared with the prior art, the prefabricated highway culvert segment structure provided by this utility model, through the cooperation between the splicing block mechanism and the splicing groove mechanism, can easily guide the water accumulated at the splicing point into the drainage groove, so that the water can be guided into the docking hole through the through hole, and then discharged into the drainage channel. This can promptly drain the water at the top of the culvert segment, effectively preventing water from staying at the top of the culvert segment for a long time, and thus preventing water from seeping into the culvert through the gaps at the splicing point. This solves the problem of easy water leakage inside the culvert in the prior art and brings more convenience to the use.

[0017] The sealing structure works together to effectively improve the sealing performance at the joint of culvert segments, and can further prevent water leakage. This is achieved by the outer sealing ring embedded around the outer periphery of the sealing ring seat and the second sealing groove corresponding to the inner wall of the outer limiting ring, the inner sealing ring embedded on the inner wall of the sealing ring seat and the first sealing groove corresponding to the outer periphery of the inner limiting ring, the guide slope opened on one side of the outer limiting ring and the inner limiting ring, and the corresponding sealing ring installed on the outer periphery and the inner wall of the sealing ring seat.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 5 As shown:

[0028] Example 1:

[0029] This utility model provides a prefabricated highway culvert segment structure, including:

[0030] The culvert segment mechanism 1, the splicing block mechanism 2 assembled on one side of the culvert segment mechanism 1, and the splicing groove mechanism 3 assembled on the other side of the culvert segment mechanism 1;

[0031] The culvert segment mechanism 1 includes a segment body 11, and a drainage channel 16 is provided inside the segment body 11 near the top.

[0032] The splicing block mechanism 2 includes a sealing ring seat 21 connected to one side of the segment body 11. The sealing ring seat 21 has a docking hole 22 corresponding to the drainage channel 16 inside, and a guide hole 23 communicating with the docking hole 22 is opened on the top of the sealing ring seat 21.

[0033] The splicing groove mechanism 3 includes an outer limiting ring 31 and an inner limiting ring 32 respectively installed on the other side of the segment body 11. The sealing ring seat 21 is inserted between the outer limiting ring 31 and the inner limiting ring 32. The top of the outer limiting ring 31 is provided with a flow channel 37, and the bottom of the flow channel 37 is provided with a through hole 38 corresponding to the flow guide hole 23.

[0034] As can be seen from the above, by inserting the sealing ring seat 21 into the cavity between the outer limiting ring 31 and the inner limiting ring 32, multiple segment bodies 11 can be easily spliced ​​end to end, enabling a sealing effect to be formed between the sealing ring seat 21, the outer limiting ring 31, and the inner limiting ring 32. At the same time, it allows the through hole 38 to guide the flow hole.

[0035] The corresponding connection between 23 enables the docking hole 22 and the drainage channel 16 to be connected.

[0036] When water accumulates on the road surface, it first gathers at the top of segment 11. At this time, since the outer limiting ring 31 has a drainage groove 37 at its top, the water near the splicing joint can flow into the drainage groove 37. The water will then flow into the guide hole 23 at the top of the sealing ring seat 21 through the through hole 38 at the bottom of the drainage groove 37, and then into the docking hole 22 connected to it through the guide hole 23. This allows the water to be guided into the drainage channel 16, thereby timely draining the water from the top of segment 11. This effectively avoids the problem of water seeping into the culvert through the splicing joint gaps due to long-term retention, and reduces the possibility of water leakage inside segment 11.

[0037] From the appendix Figure 1 It can be seen that operating cavities 12 are provided at the four corners of the inner wall of the segment body 11, and fixing holes 13 are provided on the inner wall of the operating cavity 12.

[0038] As can be seen from the above, the operating cavity 12 not only provides a convenient operating space for construction personnel, facilitating the inspection and maintenance of the internal structure of the segment 11, but also allows for the insertion of bolt fasteners through the fixing holes 13. The operating cavity 12 facilitates the tightening of bolt fasteners, enabling the easy locking and fixing of adjacent segments 11 to ensure the overall structural integrity of the culvert.

[0039] For details, please refer to the appendix. Figure 2As shown, mounting bases 14 are fixedly installed on both sides of the segment body 11, and mounting holes 15 are opened on the surface of the mounting bases 14.

[0040] As can be seen from the above, by inserting bolts into the mounting holes 15, the mounting base 14 can be firmly connected to the base or other structures on the ground, ensuring the stable placement of the segment 11 in the highway, preventing the segment 11 from shifting or shaking due to vehicle movement or other external forces, and improving the safety and reliability of the entire highway culvert system.

[0041] For details, please refer to the appendix. Figure 3 and attached Figure 4 As shown, an outer sealing ring 24 is inlaid and installed around the outer sealing ring seat 21, and a second sealing groove 36 corresponding to the outer sealing ring 24 is opened on the inner wall of the outer limiting ring 31.

[0042] As can be seen from the above, since the outer sealing ring 24 is made of rubber material, when the sealing ring seat 21 is inserted between the outer limiting ring 31 and the inner limiting ring 32, the outer sealing ring 24 can be tightly fitted into the second sealing groove 36, and a sealing operation can be performed between the sealing ring seat 21 and the outer limiting ring 31.

[0043] Working principle: By inserting the sealing ring seat 21 between the outer limiting ring 31 and the inner limiting ring 32, multiple segment bodies 11 can be easily spliced ​​together. The drainage groove 37 can guide the water near the splicing position into the drainage groove 37, so that the water can be guided into the drainage hole 23 through the through hole 38. The drainage hole 23 can drain the water into the docking hole 22, so that the water can be guided into the drainage channel 16 through the docking hole 22. The drainage channel 16 can actively drain the water, effectively draining the water on the top of the segment body 11, reducing the accumulation of water and the possibility of water seeping into the splicing gap and causing leakage.

[0044] Example 2:

[0045] Reference Appendix Figure 3 and attached Figure 4 As shown, an inner sealing ring 26 is embedded in the inner wall of the sealing ring seat 21, and a first sealing groove 34 corresponding to the inner sealing ring 26 is opened on the outer periphery of the inner limiting ring 32.

[0046] As can be seen from the above, since the inner sealing ring 26 is also made of rubber material, when the sealing ring seat 21 is inserted between the outer limiting ring 31 and the inner limiting ring 32, the inner sealing ring 26 can be tightly fitted into the first sealing groove 34. This, together with the outer sealing ring 24, can easily form a double sealing barrier, effectively improving the sealing effect, preventing water leakage, and providing a reliable guarantee for the normal use of highway culverts.

[0047] Reference Appendix Figure 4and attached Figure 5 As shown, a guide slope 33 is provided on one side of the outer limiting ring 31 and the inner limiting ring 32, and a sealing ring 25 corresponding to the guide slope 33 is installed on the outer periphery and inner wall of the sealing ring seat 21.

[0048] As can be seen from the above, when the sealing ring seat 21 contacts the guide slope 33, the sealing ring seat 21 can slide along the guide slope 33, and can quickly slide the sealing ring seat 21 between the outer limit ring 31 and the inner limit ring 32, which can play a positioning role for the sealing ring seat 21, reducing the difficulty of splicing. At the same time, after the splicing is completed, the sealing ring 25 can fit against the surface of the guide slope 33. The shape of the sealing ring 25 fits against the inclined surface of the guide slope 33, which can conveniently seal the cavity generated between the guide slope 33 and the sealing ring seat 21, thus enhancing the sealing effect.

[0049] Reference Appendix Figure 4 As shown, a support frame 39 is fixedly installed on the inner wall of the drainage channel 37, and a filter plate 35 is placed on the top of the support frame 39.

[0050] As can be seen from the above, the filter plate 35 can be easily supported by the support frame 39. After the segment body 11 is assembled, the filter plate 35 can be easily placed on the support frame 39 so that the filter plate 35 can cover the inlet position of the drainage channel 37. This can intercept and block the surrounding soil and gravel, and allow the accumulated water to flow smoothly into the drainage channel 37, avoiding the situation where soil and gravel enter the drainage channel 37 and cause blockage and poor drainage.

[0051] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
