Description

Technical Field

[0001] The utility model relates to the technical field of road subgrade, in particular to a subgrade reinforcement structure using lime-soil piles. Background Art

[0002] The roadbed is the basic structure under the railway track or road surface. It is a linear structure built with soil or stone. The materials for building the roadbed, whether filling or digging, are mainly loose materials such as soil and stone. At present, there are many methods for foundation treatment and reinforcement, such as preloading method, replacement method, vibration compaction method and lime-soil pile reinforcement, among which lime-soil pile reinforcement is to use the method of driving steel casing to make holes in the foundation, and through the extrusion effect, the foundation is densified, and then the holes are filled with plain soil in layers and compacted to form soil piles or lime-soil piles.

[0003] Please refer to the announcement number CN213867145U for a roadbed reinforcement structure using lime-soil piles. The patent states that "the lime-soil pile structure in the prior art cannot be directly connected to the superstructure to play a supporting and reinforcing role when it is hit by natural disasters such as earthquakes, which makes the reinforced roadbed's resistance capacity worse and the use effect is poor"; the lime-soil pile of the patent is provided with a first clip and a second clip, which are buckled on the high-strength geogrid, thereby enhancing the firm strength of the high-strength geogrid and improving the stability of the roadbed; springs are provided between the first clip and the protrusion and between the second clip and the protrusion, which can improve the efficiency of assembling the clip and the high-strength geogrid.

[0004] However, when installing the first clip and the second clip provided in the above patent, it is necessary to first open grooves in the compacted ash soil piles; since the compacted ash soil piles are tight and stable, during the grooving process, not only is the operation difficult, but it is also easy to damage the structure of the ash soil piles, resulting in poor use effect, and after the grooving is completed, it is not convenient to set the structure of the fixed protrusion, and the unstable installation of the protrusion can easily lead to the weakening of the reinforcement effect of the first clip and the second clip on the roadbed; in view of this, the present application proposes a roadbed reinforcement structure using ash soil piles.

[0029] In this embodiment, the connection reinforcement mechanism includes a mounting block 8 installed inside the base layer 1, and a plurality of reinforcement grooves 802 are opened on the outer side of the mounting block 8. Reinforcement rods 9 are rotatably connected in the reinforcement grooves 802 of the mounting block 8. There are multiple reinforcement rods 9, and the reinforcement rods 9 are staggered on the outer side of the mounting block 8. When the reinforcement rods 9 are unfolded, the reinforcement rods 9 and the reinforcement grooves 802 are used to improve the connection stability between the mounting block 8 and the ash-soil pile body 2.

[0030] Among them, a limiting structure for limiting the rotation of the reinforcing rod 9 is arranged inside the mounting block 8, and the limiting structure includes a rotating block 15 rotatably connected to the inside of the mounting block 8, and a limiting block 16 is fixedly connected to the outer side of the rotating block 15, so that the limiting block 16 can be driven to rotate by the rotating block 15. The limiting block 16 is eccentrically arranged on the rotating block 15, and a limiting groove that is slidably adapted to the limiting block 16 is opened at one end of the reinforcing rod 9 away from the mounting block 8, so that the limiting block 16 can be conveniently engaged with the reinforcing rod 9 by using the limiting groove, thereby facilitating limiting the rotation of the reinforcing rod 9, so as to facilitate folding the reinforcing rod 9 into the reinforcing groove 802.

[0031] Among them, a ash soil pile body 2 is arranged on the outer side of the mounting block 8, and a drainage pipe 17 is arranged inside the base layer 1 and is located on the right side of the ash soil pile body 2, so that the drainage pipe 17 can be used to guide the flow of liquid to avoid the accumulation of water on the roadbed from endangering the firmness and stability of the roadbed. A positioning block 803 is fixedly connected to the bottom of the mounting block 8, so that the positioning block 803 can be used to facilitate the positioning and installation of the mounting block 8. A limiting buckle 13 for clamping the geogrid 3 is movably connected to the top of the mounting block 8, and an adjusting component for adjusting the position of the limiting buckle 13 is arranged inside the mounting block 8.

The bottom of the limiting buckle 13 is fixedly connected with a stud 14 threadedly connected to the movable plate 11, which is convenient for fixing the limiting buckle 13 on the top of the movable plate 11 with the stud 14. The bottom of the limiting buckle 13 is provided with a slot 1301 adapted to the ribs on the geogrid 3, which is convenient for the limiting buckle 13 to use the slot 1301 to clamp the ribs on the geogrid 3, thereby enhancing the firmness of the geogrid 3.

[0034] The beneficial effects of the above embodiments are:

[0035] The roadbed reinforcement structure using lime-soil piles can buckle the limit buckle 13 set in the installation block 8 on the geogrid 3, and the installation block 8 is fixed in the lime-soil pile body 2, so as to facilitate the connection effect between the lime-soil pile body 2 and the roadbed structure, and effectively improve the strength and stability of the roadbed structure;

[0040] During construction, the reinforcing rods 9 of the lowest layer of the installation block 8 are first deployed and filled with a layer of ash soil. After compaction, the other layer of reinforcing rods 9 below can be opened and filled with ash soil again, thereby facilitating the layered compaction of the ash soil pile body 2, so that the reinforcing rods 9 and the reinforcing grooves 802 can be used to improve the connection stability between the installation block 8 and the ash soil pile body 2 while ensuring the strength of the ash soil pile body 2;

[0041] Afterwards, the geogrid 3 can be installed on the base layer 1, and the limit buckle 13 can be fixed to the top of the movable plate 11 by using the stud 14, so that the limit buckle 13 is buckled on the geogrid 3, thereby improving the connection effect between the ash soil pile body 2 and the roadbed structure, thereby enhancing the firmness of the geogrid 3. After completing the construction of the ash soil cushion layer 4, embankment 5, roadbed inner layer 6 and roadbed surface layer 7 in sequence, the purpose of improving the connection effect between the ash soil pile body 2 and the roadbed structure can be achieved, and the strength and stability of the roadbed structure can be effectively improved.
