Description

Technical Field

[0001] The utility model belongs to the technical field of culverts, and in particular relates to a drainage culvert. Background Art

[0002] Culverts refer to drainage holes (water passages) built on the roadbed and below the road surface during highway construction, in order to allow the highway to pass through the canal smoothly without hindering traffic. This structure allows water to flow under the highway. It is used to drain floods across natural valleys and depressions, or to cross large and small roads as a traffic passage for people, livestock and vehicles, or as a canal for farmland irrigation.

[0003] In order to simplify the construction process, precast concrete drainage pipes (i.e. culverts) are usually laid in the water channel, and the top is filled with soil or concrete is poured to form a culvert (the culvert below is used for drainage, and the road surface formed above is used as a cross-traffic passage for people, livestock and vehicles).

[0004] However, there are certain defects in the existing construction technology, that is, directly backfilling gravel or pouring concrete on the top of the culvert. When the road surface above the culvert is used as a normal elevated traffic lane, the force from above will be directly applied to the culvert below. Moreover, since the inside of the culvert is hollow, the culvert is prone to collapse when it is subjected to a large external force, which not only affects the normal traffic on the road, but also affects the drainage below. Utility Model Content

[0005] The utility model provides a drainage culvert, which solves the defect in the prior art that directly backfilling gravel or pouring concrete on the top of the culvert causes the culvert to collapse easily, thus affecting normal traffic and drainage.

[0006] In order to achieve the above object, the technical solution adopted by the utility model is: a drainage culvert, which comprises:

[0007] A cap assembly, the cap assembly comprising a cap, a pipe culvert arranged on the top of the cap, and an abutment integrally connected to the top of the cap and arranged obliquely;

[0008] A capping assembly, the capping assembly comprising a capping fixed on the top of the capping platform, a ring rib fixed on the bottom of the capping, and an annular groove arranged at the bottom of the ring rib;

[0009] The pipe culvert is arranged between the pipe culvert groove and the annular groove.

[0010] Optimally, it also includes wing walls fixed on both sides of the base assembly and a second inclined platform obliquely arranged on the outside of the wing walls.

[0011] Optimally, the pedestal assembly also includes a plain concrete layer fixed to the bottom of the pedestal, pedestal reinforcement embedded in the pedestal, a first circumferential reinforcement wrapped around the pedestal reinforcement, and a first buckle ring integrally connected to both ends of the first circumferential reinforcement, and the first buckle ring is buckled on the first circumferential reinforcement.

[0012] Optimally, the capping assembly further comprises a first inclined platform integrally connected to both sides of the capping, and a first capping rib and a second capping rib cross-embedded inside the capping, and the annular rib is fixed at the bottom of the first capping rib and the second capping rib.

[0013] Optimally, the wing wall includes a horizontal wing wall, a vertical wing wall fixed at intervals on the top of the horizontal wing wall, and a mounting groove arranged between the vertical wing walls, and both ends of the culvert are fixed in the mounting groove.

[0014] Optimally, the wing wall also includes flat wing wall bars embedded in the horizontal wing wall, vertical wing wall bars embedded in the vertical wing wall, second circumferential bars wrapped around the flat wing wall bars and the vertical wing wall bars, and second buckles integrally connected to both ends of the second circumferential bars, and the second buckles are buckled on the flat wing wall bars and the vertical wing wall bars.

[0015] Optimally, it also includes an expansion joint arranged between the wing wall and the second ramp and a caulking plate arranged in the expansion joint.

[0016] Optimally, the slope of the first ramp is greater than the slope of the second ramp.

[0017] Optimally, the caulking board is a polyethylene board.

[0018] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0019] The utility model provides a drainage culvert tunnel to support the internal culvert by setting a culvert trench, and by setting an inclined abutment on the top of the cap, the contact area with the internal culvert can be increased, thereby improving the stability of the culvert fixation; and the inclined abutment has a resisting effect on the culvert on the culvert trench, thereby preventing the culvert from rolling down from the culvert trench during construction; when the pressure top is fixed on the cap, the bottom surface structure of the pressure top cooperates with the top structure of the cap, and when the pressure top is subjected to the downward force applied from the outside, the inclined design of the top of the abutment can prevent the force from being directly loaded on the culvert, thereby protecting the integrity of the culvert structure and preventing the culvert from collapsing;

[0020] At the same time, the existence of the annular groove leaves a certain gap between the upper pressure top and the lower culvert. When the pressure top is subjected to the downward force applied from the outside, the existence of the gap ensures that the external force will not be directly and completely loaded to the top of the culvert, thereby protecting the integrity of the culvert structure to the greatest extent, avoiding the collapse of the culvert, ensuring the safety of the road, and will not affect drainage and flood discharge.

[0036] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0037] like Figure 1 The figure shows the structure of the drainage culvert of the utility model, which can quickly drain the surface water along the highway without affecting the traffic and ensure the safety of the roadbed. It includes a cap assembly 1, a pipe culvert 2, a capping assembly 3, a wing wall 4, an expansion joint 5, a caulking plate 6 and a second inclined platform 7.

[0038] The cap assembly 1 is used as the foundation of the pipe culvert 2 to support the pipe culvert 2. The cap assembly 1 includes a plain concrete layer 10, a cap 11, an abutment 12, a cap reinforcement 13, a first surrounding reinforcement 14, a first buckle 15 and a pipe culvert groove 16. The cap 11 is fixed on the top of the plain concrete layer 10, and the plain concrete layer 10 is cast with C25 concrete. The width of the cap 11 is smaller than the width of the plain concrete layer 10. When supporting the pipe culvert 2, the plain concrete layer 10 can increase the contact area with the ground and improve the stability of the installation of the pipe culvert 2.

[0039] The pipe culvert groove 16 is opened on the top of the base 11. The pipe culvert groove 16 is arc-shaped and matches the outer wall of the pipe culvert 2 (in actual assembly, cement mortar is applied in advance in the pipe culvert groove 16, and then the pipe culvert 2 is placed in the pipe culvert groove 16 to complete the fixation of the pipe culvert 2).

[0040] like Figure 3 As shown, the abutment 12 is integrally connected to the top of the pedestal 11 and is arranged obliquely. By arranging the inclined abutment 12 on the top of the pedestal 11, the contact area with the internal pipe culvert 2 can be increased, and the stability of the fixing of the pipe culvert 2 can be improved. Moreover, the inclined abutment 12 has a resisting effect on the pipe culvert 2 on the pipe culvert groove 16, preventing the pipe culvert 2 from rolling down from the pipe culvert groove 16 during construction.

[0041] After the top pressing assembly 3 is subsequently fixed, the bottom surface structure of the top pressing assembly 30 cooperates with the top structure of the base 11. When the top pressing assembly 3 is subjected to the downward force applied from the outside, the inclined design of the top of the support 12 can prevent the force from being directly loaded on the culvert 2, thereby protecting the integrity of the structure of the culvert 2 and preventing the culvert 2 from collapsing.

[0042] like Figure 4 As shown, the cap reinforcement 13 is embedded in the cap 11 and the abutment 12, and matches the shapes of the cap 11 and the abutment 12. The first rib 14 is wound around the outside of the cap reinforcement 13. The first buckle 15 is integrally connected to both ends of the first rib 14 and buckled on the cap reinforcement 13. The cap reinforcement 13 and the first rib 14 are tied together by wire to improve the structural strength between the cap 11 and the abutment 12 (after the cap reinforcement 13 and the first rib 14 are fixed, concrete is poured thereon to form the cap 11 and the abutment 12 structure).

[0043] like Figure 4As shown, the distribution of the pedestal ribs 13 is coordinated with the structures of the pedestal 11 and the abutment 12. When the top pressure assembly 3 applies a downward force to the pedestal assembly 1, the setting of the pedestal ribs 13 can support the pedestal 11 and avoid structural damage to the pedestal 11, thereby improving the stability of the overall structure and the stability of the installation of the culvert 2.

[0044] The capping assembly 3 is fixed on the top of the cap assembly 1 to cover the internal culvert 2 to prevent the culvert 2 from collapsing. Figure 7 As shown, the capping assembly 3 includes a capping 30, a first inclined platform 31, a first capping rib 32, a second capping rib 33, an annular rib 34 and an annular groove 35. The first capping rib 32 and the second capping rib 33 are cross-embedded in the capping 30 to improve the structural strength of the capping 30.

[0045] The bottom of the first pressure rib 32 and the second pressure rib 33 are fixed with an annular rib 34 , the bottom of the annular rib 34 forms an annular groove 35 matched with the pipe culvert 2 , and the bottom of the pressure rib 30 matches with the top structure of the abutment 12 .

[0046] like Figure 7 As shown, when the pressure top 30 is fixed on the base 11, the bottom structure of the pressure top 30 cooperates with the top structure of the base 11. When the pressure top 30 is subjected to the downward force applied from the outside, the inclined design of the top of the support 12 can avoid the force being directly loaded on the culvert 2, thereby protecting the integrity of the structure of the culvert 2 and avoiding the collapse of the culvert 2.

[0047] At the same time, the presence of the annular groove 35 leaves a certain gap between the upper pressure top 30 and the lower culvert 2. When the pressure top 30 is subjected to the downward force applied from the outside, the presence of the gap ensures that the external force will not be directly and completely loaded onto the top of the culvert 2, thereby protecting the integrity of the culvert 2 structure to the greatest extent and avoiding the collapse of the culvert 2.

[0048] The first inclined platform 31 is obliquely arranged on both sides of the top pressing part 30 . The inclined first inclined platform 31 can ensure that the structure of the top pressing part 30 is more stable and prevent the top pressing part 30 from sliding outward.

[0049] The wing walls 4 are arranged on both sides of the cap assembly 1, and the wing walls 4 are mainly used to reduce the slope, thereby improving the stability of the cap 11 and the cap 30 structure. Figure 5 , 6 As shown, the wing wall 4 includes a horizontal wing wall 41, a vertical wing wall 42, a mounting groove 43, a flat wing wall rib 44, a vertical wing wall rib 45, a second rib 46 and a second buckle 47. The vertical wing wall 42 is fixed at intervals on the top of the horizontal wing wall 41, and a mounting groove 43 is formed between the horizontal wing wall 41 and the vertical wing wall 42. The mounting groove 43 is in a "[" shape, and the opening of the "["-shaped mounting groove 43 faces upward.

[0050] Both ends of the pipe culvert 2 are installed in the installation groove 43, and the gap between the pipe culvert 2 and the installation groove 43 is coated with cement mortar to improve the structural stability of the pipe culvert 2. In addition, the installation groove 43 can limit the internal pipe culvert 2 to prevent the pipe culvert 2 from shaking left and right.

[0051] like Figure 6 As shown, the flat wing wall bars 44 are embedded in the horizontal wing wall 41 at intervals, and at least two layers ( Figure 6 The upper flat wing wall reinforcement 44 is used to improve the structural strength of the top of the horizontal wing wall 41, and the lower flat wing wall reinforcement 44 is used to improve the structural strength of the bottom of the horizontal wing wall 41. After the pipe culvert 2 is loaded, the horizontal wing wall 41 is prevented from collapsing, which causes the pipe culvert 2 to loosen and affects the drainage effect.

[0052] The vertical wing wall bars 45 are embedded in the vertical wing wall 42 at intervals and have at least two layers ( Figure 6 The inner and outer layers are shown). The inner layer of the vertical wing wall reinforcement 45 is used to improve the structural strength of the inner side of the vertical wing wall 42, and the outer layer of the vertical wing wall reinforcement 45 is used to improve the structural strength of the outer side of the vertical wing wall 42. This prevents the vertical wing wall 42 from collapsing and deforming, causing the internal pipe culvert 2 to loosen.

[0053] The second reinforcement 46 is wound around the flat wing reinforcement 44 and the vertical wing reinforcement 45, and the second buckle 47 is integrally connected to both sides of the second reinforcement 46 to fix the flat wing reinforcement 44 and the vertical wing reinforcement 45. After the flat wing reinforcement 44 and the vertical wing reinforcement 45 are fixed, concrete is poured to form the wing wall 4 structure.

[0054] The second inclined platform 7 is fixed obliquely on the outer side of the wing wall 4. Since the wing wall 4 is vertically arranged, the wing wall 4 is supported by the inclined second inclined platform 7 to improve the stability of the overall structure.

[0055] like Figure 1 As shown, the slope of the first ramp 31 is greater than the slope of the second ramp 7, and the wing wall 4 is arranged between the first ramp 31 and the second ramp 7 to play a role in reducing the slope, thereby improving the safety of the road and the stability of the structure.

[0056] like Figure 2 As shown, an expansion joint 5 is provided between the wing wall 4 and the second ramp 7, and a caulking plate 6 is provided in the expansion joint 5. The caulking plate 6 is made of a polyethylene plate. The strength and toughness of the polyethylene plate are utilized to withstand the pressure and weight of the wing wall 4. At the same time, the polyethylene plate also has a waterproof function to prevent external moisture from penetrating into the gap and causing cracks at the connection of the pipe culvert 2.

[0057] The drainage culvert of the utility model supports the internal culvert 2 by setting a culvert groove 16, and by setting an inclined abutment 12 on the top of the pedestal 11, the contact area with the internal culvert 2 can be increased, and the stability of the fixation of the culvert 2 can be improved. Moreover, the inclined abutment 12 has a resisting effect on the culvert 2 on the culvert groove 16, preventing the culvert 2 from rolling down from the culvert groove 16 during construction; when the pressure top 30 is fixed on the pedestal 11, the bottom surface structure of the pressure top 30 cooperates with the top structure of the pedestal 11, and when the pressure top 30 is subjected to the downward force applied from the outside, the inclined design of the top of the abutment 12 can prevent the force from being directly loaded on the culvert 2, thereby protecting the integrity of the culvert 2 structure and preventing the culvert 2 from collapsing;

[0058] At the same time, the presence of the annular groove 35 leaves a certain gap between the upper pressure top 30 and the lower culvert 2. When the pressure top 30 is subjected to the downward force applied from the outside, the presence of the gap ensures that the external force will not be directly and completely loaded onto the top of the culvert 2, thereby protecting the integrity of the structure of the culvert 2 to the greatest extent, avoiding the collapse of the culvert 2, and ensuring the safety of the road.

[0059] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
