[0002] Steel plate embankment box is a kind of material commonly used in road foundation engineering, it has the advantages such as high strength, good stability, construction is convenient, therefore, it has been widely applied in road construction, steel plate embankment box is mainly composed of a framework, framework is formed by longitudinal main reinforcement framework and transverse framework, the surface of framework is sealed with a patterned antiskid steel plate, and the reverse is sealed with flat steel plate, and the whole forms a box, in garbage landfill, steel plate embankment box can increase the direct contact area with garbage, improve the bearing capacity of garbage, and be used as temporary road for vehicle to pass through, to solve the problem of vehicle entering landfill.

[0003] When vehicle works in garbage landfill, the lower embankment is relatively soft and unevenly dense garbage, so when vehicle is rolled on steel plate embankment box, the compression end of steel plate embankment box is prone to sink, and the other end is prone to lift, thereby causing adverse effects on the stability of vehicle driving, and steel plate embankment box needs to be replaced as a whole after deformation, thereby increasing the use cost of embankment box.

[0004] Therefore, in view of the fact that steel plate embankment box in garbage landfill is prone to sink at compression end when being rolled, and the other end is prone to lift, and steel plate embankment box needs to be replaced as a whole after deformation, garbage landfill prefabricated steel plate embankment box mounting structure can be designed to splice multiple steel plate embankment boxes together, increase the friction between the lower end of steel plate embankment box and embankment, and replace parts of steel plate embankment box, thereby solving the above problems. INNOVATION CONTENT

Furthermore, when the steel plate roadbed box deforms, the deformation of the top cover plate is greater than that of the longitudinal and transverse frames at the lower end of the cover plate, and the deformation of the longitudinal and transverse frames is greater than that of the bottom end of the box base. Therefore, when the steel plate roadbed box deforms, the cover plate and inner frame should be removed in time to replace the cover plate, longitudinal frames, and transverse frames, thus partially replacing the components of the steel plate roadbed box.

[0008] Preferably, a lower reinforcing rib is provided at the lower end between the two inner liner frames, and an upper reinforcing rib is provided at the upper end between the two inner liner frames. The lower reinforcing rib is fixedly connected to the box base, and the upper reinforcing rib is fixedly connected to the lower end face of the cover plate.

[0015] By setting up a base, side frames, and inner liner frames, trapezoidal inserts can be inserted into trapezoidal slots of other steel plate roadbed boxes, and multiple steel plate roadbed boxes can be spliced ​​together with bolts. At the same time, hexagonal pads not only serve as reinforcement structures for the trapezoidal inserts but also increase the friction between the lower end of the steel plate roadbed box and the roadbed, thereby preventing the steel plate roadbed box from tilting or sliding and affecting the stability of the vehicle during movement. Furthermore, when the steel plate roadbed box deforms, the cover plate and inner liner frame can be removed in time to replace the cover plate, longitudinal frame, and transverse frame, allowing for partial replacement of the steel plate roadbed box components and reducing the operating cost of the steel plate roadbed box.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figures 1-6This utility model provides an embodiment of a prefabricated steel plate roadbed box installation structure for landfills, including a box base 1; it also includes side frames 2 and inner liner frames 10. The front end and one side of the box base 1 are fixedly connected to the side frame 2, and the upper end of the box base 1 is fixedly connected to the cover plate 3. The rear end and the other side of the box base 1 are fixedly connected to two trapezoidal inserts 4. The lower end of the side frame 2 is provided with four trapezoidal slots 5. Two inner liner frames 10 are installed inside the box base 1. The inner liner frames 10 are fixedly connected to the interior of each inner liner frame 10, and the longitudinal frames 12 are fixedly connected to the transverse frames 13. After inserting the trapezoidal inserts 4 into the trapezoidal slots 5 of another steel plate roadbed box, the bolts 15 are screwed into the threaded grooves 14 on the side frame 2 to secure the trapezoidal inserts. Angle 4 is fixed in trapezoidal slot 5, and the trapezoidal shape design of trapezoidal angle 4 can reduce uneven stress at the corners of trapezoidal angle 4, so as to splice multiple steel plate roadbed boxes together. At the same time, hexagonal pad 9 can not only serve as a reinforcing structure for trapezoidal angle 4, but also increase the friction between the lower end of the steel plate roadbed box and the roadbed. When the steel plate roadbed box deforms, the deformation of the uppermost cover plate 3 is greater than that of the longitudinal frame 12 and transverse frame 13 at the lower end of the cover plate 3. The deformation of the longitudinal frame 12 and transverse frame 13 is greater than that of the bottom end of the box base 1. Therefore, when the steel plate roadbed box deforms, the cover plate 3 and inner frame 10 should be removed in time to replace the cover plate 3, longitudinal frame 12 and transverse frame 13, so as to partially replace the components of the steel plate roadbed box.

[0025] Please see Figures 2-6 In this embodiment, a lower reinforcing rib 6 is provided at the lower end between the two inner liner frames 10, and an upper reinforcing rib 7 is provided at the upper end between the two inner liner frames 10. The lower reinforcing rib 6 is fixedly connected to the box base 1, and the upper reinforcing rib 7 is fixedly connected to the lower end face of the cover plate 3. The lower reinforcing rib 6 is used to enhance the structural strength of the side frame 2, and the upper reinforcing rib 7 is used to enhance the structural strength of the cover plate 3. Threaded cylinders 8 that are fixedly connected to the box base 1 are provided at the front and rear ends and on both sides of the lower reinforcing rib 6, and threaded cylinders 8 that are fixedly connected to the lower end face of the cover plate 3 are provided at the front and rear ends and on both sides of the upper reinforcing rib 7. Hexagonal pads 9 are fixedly connected to one side and the front end of the lower end face of the box base 1, and the lower end face of the hexagonal pad 9 and the lower end face of the trapezoidal insert 4 are set at the same horizontal height.

[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 In this embodiment, five positioning grooves 11 are provided on the outer side of the inner frame 10, and the positioning grooves 11 are slidably connected to the threaded cylinder 8. Four threaded grooves 14 with their lower ends connected to the trapezoidal slot 5 are provided on the upper end surface of the side frame 2, and eight threaded grooves 14 with their lower ends connected to the threaded cylinder 8 are provided on the upper end surface of the cover plate 3. Bolts 15 are threadedly fitted in the threaded grooves 14, and the hole diameter and thread setting of the threaded grooves 14 can be threadedly fitted to the trapezoidal slot 4 and the threaded cylinder 8.

[0027] In use, after inserting the trapezoidal insert 4 into the trapezoidal slot 5 of another steel plate roadbed box, the bolt 15 is screwed into the threaded groove 14 on the side frame 2 to fix the trapezoidal insert 4 in the trapezoidal slot 5. The trapezoidal shape design of the trapezoidal insert 4 can reduce the uneven force at the corners of the trapezoidal insert 4, so as to splice multiple steel plate roadbed boxes together. At the same time, the hexagonal pad 9 can not only serve as a reinforcing structure for the trapezoidal insert 4, but also increase the friction between the lower end of the steel plate roadbed box and the roadbed, thereby preventing the steel plate roadbed box from tilting or sliding, which would affect the stability of the vehicle during movement.

[0028] Furthermore, when the steel plate roadbed box deforms, the deformation of the top cover plate 3 is greater than that of the longitudinal frame 12 and the transverse frame 13 at the bottom of the cover plate 3. The deformation of the longitudinal frame 12 and the transverse frame 13 is greater than that of the bottom of the box base 1. Therefore, when the steel plate roadbed box deforms, the cover plate 3 and the inner frame 10 should be removed in time to replace the cover plate 3, the longitudinal frame 12 and the transverse frame 13, so as to partially replace the components of the steel plate roadbed box and reduce the use cost of the steel plate roadbed box.

[0029] Through the above steps, by setting the base 1, side frame 2, and inner frame 10, the trapezoidal insert 4 is inserted into the trapezoidal slot 5 of another steel plate roadbed box, and multiple steel plate roadbed boxes can be spliced ​​together by bolts 15. At the same time, the hexagonal pad 9 not only serves as a reinforcing structure for the trapezoidal insert 4, but also increases the friction between the lower end of the steel plate roadbed box and the roadbed, thereby preventing the steel plate roadbed box from tilting or sliding, which would affect the stability of the vehicle during movement. Furthermore, when the steel plate roadbed box deforms, the cover plate 3 and inner frame 10 can be removed in time to replace the cover plate 3, longitudinal frame 12, and transverse frame 13, thus partially replacing the components of the steel plate roadbed box and reducing the usage cost of the steel plate roadbed box.
