Technical Field

[0001] The utility model relates to the technical field of concrete installation, in particular to a long-distance integral reinforced concrete box culvert and an installation structure thereof. Background Art

[0002] A box culvert is a structure that plays an important role in the engineering field. It refers to a culvert whose tunnel body is constructed with reinforced concrete box-shaped pipe sections. It is generally composed of one or more square or rectangular sections and is made of reinforced concrete or masonry. Box culverts are mainly used for drainage, water passage or as underground passages. They are widely used in water conservancy projects, so a reinforced concrete box culvert and its installation structure are needed.

[0003] After searching, the Chinese patent announcement number is: CN215593748U, which discloses a reinforced concrete box culvert and its installation structure, wherein the reinforced concrete box culvert includes a box culvert body; two first installation grooves, the two first installation grooves are symmetrically arranged on the inner walls on both sides of the box culvert body; two second installation grooves, the two second installation grooves are symmetrically arranged on the top inner wall of the box culvert body; an inner telescopic support device, the two ends of the inner telescopic support device are respectively installed in the first installation groove and the second installation groove. The reinforced concrete box culvert and its installation structure provided by the utility model form a stable triangular structure between the top plate and the side wall of the box culvert body through the inner telescopic support device, thereby enhancing the bearing strength of the box culvert body, and the inner telescopic support device is easy to adjust, and is convenient to install and disassemble; by arranging a connecting installation structure between two adjacent box culvert bodies, the connection between the two adjacent box culverts is made tighter, and separation or dislocation will not occur. However, the device does not have a reinforced support design. When a heavily loaded vehicle passes by on the road above, the box culvert collapses. Since the box culvert is under great pressure, its own concrete and steel structure cannot effectively disperse and withstand these external forces. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a long-distance integral reinforced concrete box culvert and its installation structure, aiming to improve the design of the existing technology. However, the device has no reinforced support. When a heavily loaded vehicle passes by on the road above, the box culvert collapses. Since the box culvert is under great pressure, its own concrete and steel structure cannot effectively disperse and withstand these external forces.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a long-distance integral reinforced concrete box culvert and its installation structure, comprising two box culverts, a plurality of square grooves are provided on the left and right sides of the top of the top box culvert, a plurality of fixing blocks are provided on the inner sides of the square grooves, a plurality of supporting plates are fixedly connected to the top of the outer walls of the fixing blocks, a plurality of mounting holes are provided in the middle of the bottom end of the top box culvert, a plurality of docking blocks are fixedly connected to the left and right sides of the bottom end of the top box culvert, a plurality of circular holes are provided in the middle of the top end of the bottom box culvert, a plurality of mounting columns are fixedly connected to the inner walls of the plurality of circular holes, a plurality of mounting grooves are provided on the left and right sides of the top end of the bottom box culvert, a plurality of mounting holes are engaged with a plurality of mounting columns, a plurality of docking blocks are engaged with the docking grooves, and a connecting mechanism is provided on the front side of the box culvert.

[0006] Through the above technical solution: through two box culverts, the top box culvert has square grooves and a support plate connected to the fixed block on the left and right sides of the top, and has a mounting hole and a docking block at the bottom. The top of the bottom box culvert has a round hole, a mounting column and a docking groove. The longitudinal and transverse connections are achieved by engaging the mounting hole and the mounting column, and the docking block and the docking groove. This structure and connection method can effectively prevent the box culvert from collapsing and dislocating, improve its safety and reliability when under pressure, and meet engineering needs.

[0007] As a further description of the above technical solution:

[0008] The connecting mechanism includes a connecting groove, which is opened on the front side of the box culvert. A plurality of mounting holes 2 are provided at the upper and lower ends of the inner wall of the connecting groove. A plurality of connecting columns are fixedly connected to the inner walls of the plurality of mounting holes 2. A groove 1 is provided at the upper and lower ends of the middle part of the front side of the two box culverts. A connecting block is fixedly connected to the inner walls of the two grooves 1, and a groove 2 is provided on the front side of the two connecting blocks.

[0009] Through the above technical solution: the connecting mechanism includes a connecting groove opened on the front side of the box culvert, and there are two mounting holes with connecting columns at the upper and lower ends of the inner wall of the connecting groove. There are one groove with a connecting block at the upper and lower ends of the middle part of the front sides of the two box culverts, and there is also a groove two on the front side of the connecting block. When connected, the connecting groove of one box culvert corresponds to the connecting block of another box culvert, and the connecting column in the connecting groove is inserted into the related structure of the other box culvert connecting block, and together with other connecting structures, ensure that the box culvert system is complete and stable, withstands loads and avoids dislocation.

[0010] As a further description of the above technical solution:

[0011] A plurality of circular holes 1 are provided on the left and right sides of the top of the box culvert, the inner walls of the plurality of circular holes 1 are fixedly connected with support columns, and the other ends of the plurality of support columns are fixedly connected with support plates 1.

[0012] Through the above technical solution: multiple circular holes are opened on the left and right sides of the box culvert top, the inner wall of the circular hole is fixedly connected to the support column, and the other end of the support column is fixedly connected to the support plate. When there is a load above the box culvert, the load can be evenly distributed to the support column through the support plate, and then transmitted to the top of the box culvert to share the pressure and prevent damage to the top. At the same time, under the action of lateral force, the lateral displacement of the box culvert can be limited to enhance the overall stability.

[0013] As a further description of the above technical solution:

[0014] The left and right sides of the outer wall of the box culvert at the top are both provided with weight-reducing openings, and the tops of the two weight-reducing openings are both provided with hooks.

[0015] Through the above technical solution: weight-reducing openings are provided on the left and right sides of the outer wall of the top box culvert, which reduces the weight of the box culvert without affecting the overall structural strength and performance of the box culvert, reduces the pressure on the foundation, and reduces the cost of foundation treatment. At the same time, the hooks opened on the top of the two weight-reducing openings can be used as lifting points during the construction process, facilitating the prefabrication, transportation and installation of the box culvert.

[0016] As a further description of the above technical solution:

[0017] A second support plate is fixedly connected to the middle of the bottom end of the box culvert, and two support columns are fixedly connected to the left and right sides of the bottom of the second support plate.

[0018] Through the above technical solution: support plate two is fixedly connected to the middle part of the bottom end of the box culvert, and support columns two are fixedly connected to the left and right sides of the bottom of support plate two, so that support plate two provides additional support and stability for the box culvert, and support column two further enhances the supporting effect of the bottom of the box culvert. When the box culvert is subjected to upper pressure and lateral force, support column two can disperse the force, reduce the local pressure at the bottom of the box culvert, and together with support plate two form a stable support system, thereby improving the bearing capacity and anti-deformation ability of the box culvert under various complex working conditions.

[0019] As a further description of the above technical solution:

[0020] The front and rear sides of the bottom of the box culvert are both fixedly connected with connecting blocks 2, and the bottoms of the two connecting blocks 2 are both fixedly connected with bottom plates.

[0021] Through the above technical solution: the connecting block 2 fixedly connected to the front and rear sides of the box culvert bottom plays a connecting and transitional role between the box culvert and the bottom plate, thereby enhancing the stability and reliability of the connection between the bottom of the box culvert and the bottom plate, and evenly transmitting the force borne by the box culvert to the bottom plate. The bottom plate provides a stable basic support for the box culvert, disperses the pressure to the foundation, and prevents the bottom of the box culvert from directly contacting the foundation to reduce damage.

[0022] As a further description of the above technical solution:

[0023] The left and right sides of the bottoms of the two bottom plates are fixedly connected with positioning columns, and the bottoms of the two positioning columns are fixedly connected with positioning cones.

[0024] Through the above technical solution: positioning columns are fixedly connected to the left and right sides of the bottom of the two base plates, and the positioning columns extend downward from the base plates, thereby enhancing the connection stability between the base plates and the ground or foundation, and preventing the box culvert from moving horizontally. The positioning cone at the bottom of the positioning column is conical, which can be more easily inserted into the ground or foundation when the box culvert is installed, thereby increasing the contact area and friction between the positioning column and the ground, making the box culvert more stable when subjected to external force and not easy to move.

[0025] As a further description of the above technical solution:

[0026] The left and right sides of the bottom of the inner wall of the box culvert are both provided with water leakage holes, and the tops of the plurality of support plates are all provided with obstruction grooves.

[0027] Through the above technical solution: water accumulated in the box culvert can be discharged through the leakage holes on the left and right sides of the bottom inner wall of the box culvert, such as the accumulated water caused by rainwater infiltration or groundwater infiltration, to avoid the accumulated water from damaging the box culvert structure and extend its service life. On the one hand, the barrier grooves on the top of the multiple support plates can increase the friction between the support plates and the upper structure, improve the overall stability of the box culvert, and prevent relative sliding when there is pressure from above.

[0028] The utility model has the following beneficial effects:

[0029] 1. In the present invention, the mounting hole at the bottom of the top box culvert engages with the mounting post at the top of the bottom box culvert, thereby achieving a precise vertical connection of the box culvert, ensuring the integrity of the upper and lower box culverts. When bearing the vehicle load and roadbed pressure of the road above, the stability of the structure can be maintained, thereby improving the bearing capacity of the box culvert.

[0030] 2. In the present invention, the cooperation between the connecting groove and the connecting block makes the box culvert more convenient during installation. The construction workers can quickly connect the box culverts by inserting the connecting column into the second installation hole and aligning the connecting block with the connecting groove. This simple operation method greatly improves the construction efficiency and shortens the construction period. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] 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.

[0039] Reference Figure 1 、 Figure 2 and Figure 5The utility model provides an embodiment of a long-distance integral reinforced concrete box culvert and its installation structure, comprising two box culverts 1, a plurality of square grooves 3 are opened on the left and right sides of the top of the top box culvert 1, a plurality of fixing blocks 4 are opened on the inner sides of the plurality of square grooves 3, and a plurality of outer wall tops of the fixing blocks 4 are fixedly connected with a support plate 5 to enhance the overall bearing capacity of the box culvert 1. A plurality of mounting holes 6 are opened in the middle of the bottom end of the top box culvert 1, a plurality of docking blocks 7 are fixedly connected on the left and right sides of the bottom end of the top box culvert 1, a plurality of circular holes 8 are opened in the middle of the top end of the bottom box culvert 1, a plurality of mounting posts 9 are fixedly connected on the inner walls of the plurality of circular holes 8, the mounting holes 6 and the mounting posts 9 are engaged with each other, and the docking blocks 7 and the docking grooves 10 are engaged with each other to bear the load in the vertical and horizontal directions. The left and right sides of the top of the bottom box culvert 1 are opened with docking grooves 10, a plurality of mounting holes 6 are engaged with a plurality of mounting posts 9, a plurality of docking blocks 7 are engaged with the docking grooves 10, and a connecting mechanism 2 is provided on the front side of the box culvert 1;

[0040] Specifically, the top box culvert 1 is hoisted to the top of the bottom box culvert 1, and through precise positioning operations, the mounting hole 6 at the bottom of the top box culvert 1 is aligned with the mounting column 9 on the bottom box culvert 1 in the vertical direction. At the same time, ensure that the docking block 7 at the bottom of the top box culvert 1 is aligned with the docking groove 10 on the bottom box culvert 1 in the horizontal direction, and slowly lower the top box culvert 1 so that the mounting hole 6 is gradually sleeved on the mounting column 9 to achieve a vertical snap-fit ​​connection. The mounting column 9 plays a positioning and supporting role in the mounting hole 6, ensuring that the relative positions of the upper and lower box culverts 1 in the vertical direction are fixed. At the same time, as the top box culvert 1 descends, the docking block 7 is gradually inserted into the docking groove 10 to achieve a horizontal snap-fit ​​connection. The snap-fit ​​connection between the mounting hole 6 and the mounting column 9 and the snap-fit ​​connection between the docking block 7 and the docking groove 10 jointly bear the vertical and horizontal loads. The support plate 5 is connected to the top box culvert 1 through the fixing block 4, which can also share part of the load to a certain extent, thereby enhancing the overall bearing capacity of the box culvert 1.

[0041] Reference Figure 2 、 Figure 3 and Figure 4 , the utility model provides an embodiment: the connecting mechanism 2 includes a connecting groove 201, the connecting groove 201 is opened on the front side of the box culvert 1, and is used to install the box culvert 1. The upper and lower ends of the inner wall of the connecting groove 201 are provided with multiple mounting holes 202, and the inner walls of the multiple mounting holes 202 are fixedly connected with multiple connecting columns 203. The upper and lower ends of the middle parts of the front sides of the two box culverts 1 are provided with grooves 1 204, and the inner walls of the two grooves 1 are fixedly connected with connecting blocks 1 205. The front sides of the two connecting blocks 1 205 are provided with grooves 206. The connecting columns 203 in the mounting holes 202 at the upper and lower ends of the inner wall of the connecting groove 201 will gradually approach the grooves 206 on the front side of the connecting block 1 205 to achieve engagement;

[0042] Specifically, the front sides of two adjacent box culverts 1 are placed opposite each other, so that the connecting groove 201 on the box culvert 1 is aligned with the connecting block 1 205 on the other box culvert 1, and at the same time, it is ensured that the mounting holes 202 at the upper and lower ends of the inner wall of the connecting groove 201 and the groove 206 on the front side of the connecting block 1 205 are roughly corresponding in position. The connecting block 1 205 is slowly pushed into the connecting groove 201, and the connecting columns 203 in the mounting holes 202 at the upper and lower ends of the inner wall of the connecting groove 201 will gradually approach the groove 206 on the front side of the connecting block 1 205. As the connecting block 1 205 continues to penetrate into the connecting groove 201, the connecting columns 203 will be inserted into the groove 206, thereby realizing the snap connection of the connecting mechanism 2.

[0043] Reference Figure 3 、 Figure 4 and Figure 5 The utility model provides an embodiment: a plurality of circular holes 11 are opened on the left and right sides of the top of the box culvert 1, and the inner walls of the plurality of circular holes 11 are fixedly connected with support columns 12, which can distribute the load more evenly to each support column 12, and the other ends of the plurality of support columns 12 are fixedly connected with support plates 5; weight-reducing openings 13 are opened on the left and right sides of the outer wall of the top box culvert 1, and hooks 14 are opened on the tops of the two weight-reducing openings 13, which reduce the dead weight of the box culvert 1; a support plate 2 15 is fixedly connected to the middle part of the bottom end of the box culvert 1, and support columns 2 16 are fixedly connected to the left and right sides of the bottom of the support plate 2 15;

[0044] Specifically, the support column 12 transfers the load from above to the support plate 5 fixedly connected to it. Since the support plate 5 is connected to multiple support columns 12, it can distribute the load more evenly to each support column 12, thereby reducing the pressure on the top part of the box culvert 1. The weight-reducing openings 13 opened on the left and right sides of the outer wall of the top box culvert 1 reduce the material usage of the box culvert 1 without affecting the overall structural strength and performance of the box culvert 1, thereby reducing the weight of the box culvert 1.

[0045] Reference Figure 2 、 Figure 3 and Figure 4 The utility model provides an embodiment: the front and rear sides of the bottom of the box culvert 1 are fixedly connected with connecting blocks 2 17, and the bottoms of the two connecting blocks 2 17 are fixedly connected with bottom plates 18. The connecting blocks 2 17 play a transition role in connecting the box culvert 1 and the bottom plates 18; the left and right sides of the bottoms of the two bottom plates 18 are fixedly connected with positioning columns 19, and the bottoms of the two positioning columns 19 are fixedly connected with positioning cones 20. The positioning cones 20 at the bottoms of the positioning columns 19 can be more easily inserted into the ground or foundation when the box culvert 1 is installed; the left and right sides of the bottom of the inner wall of the box culvert 1 are opened with leakage holes 21, and the tops of the multiple support plates 5 are opened with obstruction grooves 22, which improve the overall stability of the box culvert 1;

[0046] Specifically, the connecting blocks 17 on the front and rear sides of the bottom of the box culvert 1 play a transitional role in connecting the box culvert 1 and the bottom plate 18. The connecting blocks 17 evenly transfer the various forces borne by the box culvert 1 to the bottom plate 18 to avoid local stress concentration. The positioning columns 19 on the left and right sides of the bottom of the bottom plate 18 extend downward from the bottom plate 18, thereby enhancing the connection stability between the bottom plate 18 and the ground or foundation. The positioning cones 20 at the bottom of the positioning columns 19 can be more easily inserted into the ground or foundation when the box culvert 1 is installed. The positioning cones 20 increase the contact surface between the positioning columns 19 and the ground. The accumulation of water increases the friction force, making the box culvert 1 more stable when subjected to external forces and less likely to be displaced. The water leakage ports 21 on the left and right sides of the bottom of the inner wall of the box culvert 1 are mainly used to discharge water that may accumulate inside the box culvert 1. In the case of rainwater infiltration, groundwater infiltration, etc., there may be water accumulation inside the box culvert 1. The water leakage ports 21 can quickly discharge the accumulated water from the box culvert 1 to keep the inside of the box culvert 1 dry. The barrier grooves 22 on the top of the multiple support plates 5 can increase the friction force between the support plates 5 and the upper structure, thereby improving the overall stability of the box culvert 1.

[0047] Working principle: Through the fixing blocks 4 and the support plate 5 structure in the multiple square grooves 3 on the left and right sides of the top of the top box culvert 1, when bearing the upper load, part of the load can be dispersed to both sides of the box culvert 1, thereby enhancing the overall bearing capacity of the box culvert 1. The top box culvert 1 is hoisted to the top of the bottom box culvert 1. Through precise positioning operations, the mounting hole 6 at the bottom of the top box culvert 1 is aligned with the mounting column 9 on the bottom box culvert 1 in the vertical direction. At the same time, ensure that the docking block 7 at the bottom of the top box culvert 1 is aligned with the docking groove 10 on the bottom box culvert 1 in the horizontal direction. This process requires the use of equipment such as a crane for precise operation to ensure the accuracy of the installation. Slowly lower the top box culvert 1 so that the mounting hole 6 is gradually fitted onto the mounting column 9 to achieve a vertical snap-in connection.

[0048] By aligning the front sides of two adjacent box culverts 1, the connecting groove 201 on the box culvert 1 is aligned with the connecting block 1 205 on the other box culvert 1, ensuring that the positions of the connecting groove 201 and the connecting block 1 205 in the horizontal direction are accurately corresponding. A plurality of mounting holes 202 are provided at the upper and lower ends of the inner wall of the connecting groove 201, and a connecting column 203 is fixedly connected in the mounting hole 202, and a groove 206 is provided on the front side of the connecting block 1 205. At this time, it is necessary to ensure that the mounting holes 202 and the groove 206 are roughly corresponding in position to prepare for the subsequent snap-fit ​​connection. The connecting block 1 205 and the connecting column 203 are finally inserted into the groove 206 to realize the snap-fit ​​connection of the connecting mechanism 2. The connecting column 203 and the groove 2 206 are tightly matched, so that the adjacent box culverts 1 are firmly connected in the front and rear directions.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
