[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see the appendix Figure 1-8 This application provides the following technical solutions.

[0027] A lightweight, quick-installable box-type thin-walled prefabricated roadbed frame slope protection module includes: slope protection abutments 1 located on the upper and lower sides of the roadbed, and a frame slope protection 2 located between the two slope protection abutments 1. The frame slope protection 2 comprises a standard precast section 3 and a cast-in-place section 4. The standard precast section 3 includes several standard straight modules 5, several standard curved modules 6, several standard node modules 7, and several cast-in-place retaining modules 8. The cast-in-place retaining modules 8 are positioned close to the cast-in-place section 4, and are located on both sides of the cast-in-place section 4. The quasi-arc module 6 is assembled with the standard straight module 5 and the cast-in-place enclosure module 8 through the standard node module 7. Before construction, a slope protection platform 1 is poured under the inclined roadbed, and the standard straight module 5 is assembled on the slope protection platform 1 as the base. As the assembly height increases, the standard node module 7 is assembled on one side of the standard straight module 5. Then, several standard arc modules 6 are assembled between two standard straight modules 5 or between the standard straight module 5 and the cast-in-place enclosure module 8 through the standard node module 7.

[0028] The dimensions of the cast-in-place enclosure module 8 are prefabricated according to the design dimensions and reserved space of the cast-in-place section 4. The only difference between the cast-in-place enclosure module 8 and the standard straight module 5 and standard node module 7 is the size and shape. However, it must be installed in conjunction with the standard curved module 6. After the skeleton slope protection 2 is assembled, the slope protection platform 1 is poured on the top of the roadbed to seal the uppermost skeleton slope protection 2.

[0029] The standard straight module 5, standard arc module 6, standard node module 7 and cast-in-place enclosure module 8 are all equipped with box-shaped grooves 9. The upper end of the standard straight module 5, standard arc module 6, standard node module 7 and cast-in-place enclosure module 8 is equipped with a water-retaining eave 10. The box-shaped grooves 9 can save concrete usage and reduce construction costs.

[0030] The socket assembly facilitates the individual assembly and joint installation of the standard straight module 5, standard curved module 6, standard node module 7, and cast-in-place enclosure module 8. The socket assembly is located on both sides of each module and includes a socket groove 12 and a socket boss 13. The vertical cross-sectional area of ​​both the socket groove 12 and the socket boss 13 is larger than that of the box-shaped groove 9. The dimensions of the socket groove 12 and the socket boss 13 are matched. Taking the standard straight module 5 as an example, after one standard straight module 5 is erected and placed on the slope protection platform 1 below the roadbed, the socket groove 12 of the second standard straight module 5 fits onto the socket boss 13 of the lower standard straight module 5, ensuring precise alignment of the two standard straight modules 5 and preventing misalignment. Furthermore, the combined structure is stable and reliable after being plugged in and stacked, and will not detach.

[0031] The auxiliary assembly components facilitate hoisting and assembly when assembling individual modules. The upper ends of the standard straight module 5, standard arc module 6, standard node module 7, and cast-in-place enclosure module 8 are all provided with assembly lifting holes 11. The auxiliary assembly components are inserted into the assembly lifting holes 11. The auxiliary assembly components include auxiliary grips 15 and lifting rings 16. The assembly lifting holes 11 are connected to the box-shaped grooves 9. The box-shaped grooves 9 are provided with auxiliary slots 14 directly below the assembly lifting holes 11. The lower end of the auxiliary grips 15 passes through the assembly lifting holes 11 and is inserted into the auxiliary slots 14. The end of the auxiliary grips 15 inside the assembly lifting holes 11 is fitted with a support rubber sleeve 24, and the end of the auxiliary grips 15 outside the assembly lifting holes 11 is provided with a lifting ring 16. When the auxiliary grips 15 passes through the assembly lifting holes 11 and is inserted into the auxiliary slots 14, the lifting ring 16 can prevent the auxiliary grips 15 from swinging excessively inside the assembly lifting holes 11.

[0032] The auxiliary grip 15 is located within the box-shaped groove 9 and has a mounting base 17 on the side near the assembly lifting hole 11. The upper end of the mounting base 17 has several symmetrically arranged inclined movable grooves 18. Each of the inclined movable grooves 18 has a claw rod 19 rotatably inserted into it via a positioning pin. The upper ends of the claw rods 19 extend out of the mounting base 17 and abut against the upper end of the box-shaped groove 9 near the assembly lifting hole 11. The upper end of the auxiliary grip 15 has a hollow groove 20. Four strip-shaped grooves are formed through the hollow groove 20 on the side outside the assembly lifting hole 11. The hollow groove 20 contains a cross-shaped lifting block 21. Four strip-shaped slots are inserted through the four sides of the cross-shaped lifting block 21. Several retractable pull ropes 22 are located at the lower end of the cross-shaped lifting block 21. A threading groove is provided on the side of the hollow groove 20 near the claw rod 19. One side of each of the retractable pull ropes 22 passes through the threading groove and connects to the claw rod 19. An unfolding counterweight block 23 is provided on the side of the claw rod 19 away from the retractable pull ropes 22. Taking the standard straight module 5 as an example, under the design effect of the unfolding counterweight block 23, when the auxiliary grip rod 1... When the auxiliary grip rod 15 passes through the assembly lifting hole 11 and is inserted into the auxiliary slot 14, it continues to descend. At this time, when the claw rod 19 passes through the assembly lifting hole 11 and is in the box-shaped groove 9, the claw rod 19 is opened to the four sides by the counterweight of the unfolded counterweight block 23. The coverage area of ​​the claw rod 19 after opening is greater than the cross-sectional area of ​​the assembly lifting hole 11. At this time, the lifting ring 16 is connected to the hook of the lifting equipment, and the auxiliary grip rod 15 is pulled upward. At this time, the claw rod 19 abuts against the upper end of the box-shaped groove 9 of the standard linear module 5. 5. The standard straight module 5 can be lifted synchronously by the claw rod 19. When the auxiliary grip rod 15 moves the standard straight module 5 to the roadbed position with the hoisting equipment, since the lower end of the auxiliary grip rod 15 is still inserted in the auxiliary slot 14, the operator holds the auxiliary grip rod 15 in the box groove 9. With the lifting force of the hoisting equipment, the standard straight module 5 can be tilted and guided, so that the standard straight module 5 can be assembled with the standard straight module 5 below the socket groove 12 and socket boss 13 with less effort.

[0033] After the standard linear module 5 is assembled, the hoisting rope of the hoisting equipment descends, and the lower end of the auxiliary grip 15 continues to move downward along the auxiliary slot 14. At this time, the claw rod 19 does not contact the standard linear module 5. The cross lifting block 21 is hooked by hand at the position where it extends out of the auxiliary grip 15 and is pulled up. The cross lifting block 21 controls the retracting rope 22 to retract the claw rod 19. At this time, in conjunction with the lifting action of the cross lifting block 21, the auxiliary grip 15 is directly pulled out from the standard linear module 5, and the hoisting and assembly of the next standard linear module 5 can be carried out. The operation is simple and worry-free. Before the completion of all construction, the assembly lifting hole 11 is sealed with concrete.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
