[0010] A splicing assembly for fixing the two splicing units is arranged between two adjacent splicing units.

[0011] By adopting the above technical solution, after the steel cage is fixed to the connection seat, the connection seat is fixed in the connection groove, and then the base is fixed to the ground by the fixing pin, thereby enhancing the connection strength between the steel cage and the ground; at the same time, the two adjacent splicing units are fixed by the splicing assembly, thereby improving the connection strength between the splicing units, thereby enhancing the integrity between the splicing units. Through the above structure, the stability of the steel cage is enhanced, thereby increasing the service life of the roadbed.

[0012] Optionally, multiple first fixing plates are arranged through the steel cage, the first fixing plates are pressed against the steel cage, a connecting screw is fixedly connected to the side of the connecting seat facing the first fixing plate, the connecting screw passes through the first fixing plate, one end of the connecting screw passes through the first fixing plate and is threadedly connected with a connecting nut, which presses against the first fixing plate.

[0013] At present, welding is mostly used, which requires additional tools and has low installation efficiency. With the above technical solution, the first fixing plate is passed through the steel cage, and then the connecting screw is passed through the connecting hole, and the first fixing plate is pressed against the steel cage through the connecting nut, thereby fixing the steel cage and the connecting seat. The connection method is simple and fast, and the installation efficiency is improved.

[0014] Optionally, a first slot adapted to fit the transverse steel bars in the steel cage is formed on a side wall of one side of the first fixing plate.

[0015] By adopting the above technical solution, the contact area between the first fixing plate and the transverse steel bars in the steel cage is increased through the first clamping groove, thereby increasing the friction between the first fixing plate and the steel cage, thereby making it difficult for the first fixing plate and the steel cage to slide, thereby improving the connection stability between the steel cage and the connecting seat.

[0016] Optionally, both ends of the first fixed plate are fixedly connected to a fixed seat, a through groove is formed in the fixed seat, the fixed seat is rotatably connected to a threaded sleeve in the through groove, a through hole is formed on the inner wall of the fixed seat at the through groove, a lead screw is slidably connected in the through hole, one end of the lead screw extends into the threaded sleeve, the lead screw and the threaded sleeve are threadedly connected, the other end of the lead screw extends out of the through hole, and one end of the lead screw extending out of the through hole is fixedly connected to a second fixed plate, and the second fixed plate is used to tighten the vertical steel bars in the steel cage.

[0017] By adopting the above technical solution, after the first fixed plate is pressed against the steel cage, the staff rotates the threaded sleeve to make the screw drive the second fixed plate to press against the vertical steel bars in the steel cage, so that it is not easy to slip between the first fixed plate and the steel cage, thereby improving the stability of the steel cage.

[0021] By adopting the above technical solution, during the movement of the lead screw, the guide block slides in the guide groove, and the guide block guides and limits the lead screw, thereby making it difficult for the lead screw to rotate with the threaded sleeve.

[0022] Optionally, the splicing assembly includes a splicing rod and a limiting rod, the splicing rod is fixedly connected to one end of the base, the other end of the base is fixedly connected to a splicing groove that is plug-in compatible with the splicing rod, the base has a limiting groove on the inner wall at the splicing groove, the limiting rod is arranged in the limiting groove and the two are slidably connected, a telescopic spring is arranged in the limiting groove, the two ends of the telescopic spring are respectively fixedly connected to the limiting rod and the base, and the side wall of the splicing rod is provided with a limiting hole that is plug-in compatible with the limiting rod.

[0024] Optionally, an inclined surface is provided on a side of the limiting rod facing away from the telescopic spring.

[0025] By adopting the above technical solution, after the splicing rod is inserted into the splicing groove, the splicing rod squeezes the inclined surface to make the limiting rod shrink into the limiting groove, thereby achieving the effect of convenient assembly.

[0026] In summary, this application includes the following beneficial technical effects:

[0027] The base is fixed to the ground by fixing pins, thereby enhancing the connection strength between the steel cage and the ground; at the same time, two adjacent splicing units are fixed by splicing components, thereby improving the connection strength between the splicing units; the first fixing plate and the second fixing plate are respectively pressed against the transverse steel bars and the vertical steel bars in the steel cage, thereby making the connection between the steel cage and the connecting seat stable.

[0034] The embodiment of the present application discloses a roadbed reinforcement structure for a highway excavation and filling section.

[0035] refer to Figure 1 A roadbed reinforcement structure for a highway excavation section includes a splicing unit, which includes a connecting component 1 and a reinforcement component 2. The connecting component 1 includes a base 11 and a connecting seat 21. The base 11 is arranged in a horizontal direction. Both sides of the base 11 are penetrated with fixing pins 12. A plurality of fixing pins 12 are arranged along the length direction of the base 11. The fixing pins 12 fix the base 11 to the ground. The upper surface of the base 11 is provided with a connecting groove 111. The reinforcement component 2 includes a connecting seat 21 and a steel cage 22 that are plugged and adapted to the connecting groove 111. The connecting seat 21 has an interference fit with the connecting seat 21, and the steel cage 22 is fixed to the connecting seat 21.

[0036] After fixing the base 11 with the fixing pin 12, the staff inserts the connecting seat 21 into the connecting groove 111 by knocking, and then fixes the steel cage 22 to the connecting seat 21, and finally splices a suitable number of splicing units according to the required length.

[0037] refer to Figure 1 and Figure 2 A first fixing plate 4 is horizontally penetrated through the bottom of the steel cage 22. Multiple first fixing plates 4 are arranged along the width direction of the steel cage 22. The first fixing plate 4 is pressed against the transverse steel bars at the bottom of the steel cage 22. A first card groove 41 is provided on the lower surface of the first fixing plate 4. The first card groove 41 is adapted to the transverse steel bars at the bottom of the steel cage 22.

[0038] refer to Figure 2A connecting screw 211 is fixedly connected to one side of the connecting seat 21 facing the first fixing plate 4. The connecting screw 211 passes through the first fixing plate 4. One end of the connecting screw 211 passing through the first fixing plate 4 is threadedly connected with a connecting nut 2111. An anti-slip pad 2112 is arranged between the connecting nut 2111 and the first fixing plate 4. The anti-slip pad 2112 is sleeved on the connecting screw 211, and the connecting nut 2111 presses against the anti-slip pad 2112 and the first fixing plate 4.

[0039] After passing the first fixing plate 4 through the bottom of the steel cage 22, the staff moves the first fixing plate 4 until the connecting screw 211 passes through the first fixing plate 4, and then puts the anti-slip pad 2112 on the connecting screw 211, and finally screws the connecting nut 2111 on the connecting screw 211 until the connecting nut 2111 is pressed against the anti-slip pad 2112 and the first fixing plate 4.

[0040] refer to Figure 2 and Figure 3 Both ends of the first fixed plate 4 are fixedly connected with a fixed seat 5, a through groove 51 is opened in the fixed seat 5, and a threaded sleeve 52 is rotatably connected to the fixed seat 5 in the through groove 51. Through holes 53 are opened on the inner walls of both sides of the through groove 51 of the fixed seat 5, and a guide block 55 is fixedly connected to the inner wall of the fixed seat 5 at the through hole 53.

[0041] refer to Figure 2 and Figure 3 A lead screw 54 is slidably connected in the through hole 53, and a guide groove 541 is provided on the outer wall of the lead screw 54 to slide with the guide block 55. One end of the lead screw 54 extends into the threaded sleeve 52 and the two are threadedly connected. One end of the lead screw 54 extending out of the through hole 53 is fixedly connected to a second fixing plate 6, and the second fixing plate 6 is used to tighten the vertical steel bars in the steel cage 22. The side wall of the second fixing plate 6 is provided with a second clamping groove 61 that is adapted to the vertical steel bars in the steel cage 22.

[0042] After fixing the first fixing plate 4, the staff rotates the threaded sleeve 52, and the threaded sleeve 52 drives the two screws 54 in the same through groove 51 to move away from each other, so that the screw 54 drives the second fixing plate 6 to press against the vertical steel bars of the steel cage 22; during the movement of the screw 54, the guide block 55 slides along the guide groove 541.

[0043] refer to Figure 4 A splicing component 3 is arranged between two adjacent splicing units, and a plurality of splicing components 3 are arranged. In the embodiment of the present application, two splicing components 3 are arranged between two adjacent splicing units, and the two splicing components 3 are respectively located on both sides of the splicing unit.

[0044] refer to Figure 4The splicing assembly 3 includes a splicing rod 31 and a limiting rod 32. The splicing rod 31 is fixedly connected to one end of the base 11, and the other end of the base 11 is fixedly connected to a splicing groove 112 that is plugged and adapted to the splicing rod 31.

An inclined surface 321 is provided on the side of the limiting rod 32 away from the telescopic spring 114, and a limiting hole 311 that is plugged and adapted to the limiting rod 32 is provided on the side wall of the splicing rod 31.

[0045] The mobile base 11 inserts the splicing rod 31 into the splicing groove 112. At this time, the splicing rod 31 squeezes and contracts the limiting rod 32 into the limiting groove 113 through the inclined surface 321 until the splicing rod 31 is completely inserted into the splicing groove 112. At this time, the limiting rod 32 is aligned with the limiting hole 311, and then the telescopic spring 114 releases the elastic force to drive the limiting rod 32 to be inserted into the limiting hole 311, thereby connecting the bases 11 in the two splicing units.

[0046] The implementation principle of the roadbed reinforcement structure of a highway excavation section in the embodiment of the present application is as follows: the worker fixes the base 11 to the ground through the fixing pin 12, then inserts the connecting seat 21 into the connecting groove 111 by knocking, then fixes the steel cage 22 to the connecting seat 21 through the first fixing plate 4 and the second fixing plate 6, and finally connects two adjacent splicing units through the splicing assembly 3.
