[0002] A composite foundation with poor geology refers to a foundation with two or more poor geological conditions, such as a composite foundation of soft soil and collapsible loess. When constructing a building on the foundation, the foundation needs to be compacted by a compaction device. A compaction device is a construction machine used for soil compaction. It can increase the density of the soil through impact, vibration or pressure, thereby improving the bearing capacity and stability of the foundation.

[0003] For example, when building a logistics warehouse on this type of foundation, a large amount of materials and goods need to be piled above the ground in the warehouse, so the foundation needs to have a large load-bearing capacity to prevent the foundation from sinking due to the weight of the goods, so a compaction device is needed to compact the foundation.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-5 The utility model provides an embodiment: a device for reinforcing and compacting a composite foundation in poor geology, including a rammer 2. Extension plates 4 are arranged around the top of the rammer 2. The extension plates 4 are only placed around the rammer 2 and there is no connection between the two. Both sides of the tops of multiple extension plates 4 are fixedly connected with mounting seats 5. The mounting seats 5 are hollow structures. Both sides of the inner walls of multiple mounting seats 5 are provided with through holes 9. Two T-slots 6 are arranged at the four corners of the top of the rammer 2. T-blocks 17 are slidably connected inside the multiple T-slots 6. Push blocks 3 are fixedly connected to the tops of multiple T-blocks 17.

[0033] An opening for installing a T-block 17 is provided at the top of the T-slot 6. After the T-block 17 is placed inside the T-slot 6, the opening is sealed by welding. The T-block 17 is made of a metal material with strong tensile strength. One end of each of the push blocks 3 is slidably connected to the inside of the mounting seat 5. Each of the push blocks 3 is provided with a mounting groove 7. Both ends of the inner sides of each of the multiple mountings are slidably connected with a protrusion 15. The other ends of each of the protrusions 15 are slidably connected to the inside of the through hole 9. Each of the multiple mounting grooves 7 is threadedly connected with a bolt 8. The other ends of each of the bolts 8 are threadedly connected to the inner top wall of the mounting seat 5. A fixing rod is fixedly connected to the adjacent side of each of the push blocks 3. Through holes through which the bolts 8 can pass are provided at both ends of each of the fixing rods.

[0034] Place the extension plate 4 around the rammer 2, then push the fixing rod to make the T-block 17 slide inside the T-slot 6. The moving T-block 17 can push the two push blocks 3 on one side of the rammer 2 to enter the mounting seat 5 at the same time, and then extend the bolt 8 into the mounting seat 5 and the mounting slot 7 in turn. When the bolt 8 enters the mounting slot 7, it will push the two protrusions 15 inside the mounting slot 7 to slide out of the mounting slot 7 and enter the through hole 9. Then tighten the bolt 8 to fix the extension plate 4 to the surrounding of the rammer 2.

[0035] A hole is provided at the top of the rammer 2 for the bolt 8 to enter. When the extension plate 4 needs to be disassembled, the bolt 8 can be unscrewed, and then the protrusion 15 is pushed to retract the protrusion 15, and the push block 3 is pushed to one side to slide out from the inside of the mounting seat 5, and drive the T-block 17 below to slide together. When the T-block 17 hits the side wall of the T-slot 6, the bolt 8 can be passed through the fixing rod and extended into the hole on the rammer 2 to be tightened, so as to fix the push block 3, and the bolt 8 can also be stored on the fixing rod.

[0036] One opposite end of the protrusion 15 is arranged in an arc shape. When the bolt 8 enters into the installation groove 7 , one end of the bolt 8 will press the arc end of the protrusion 15 to make the protrusion 15 slide inside the installation groove 7 .

[0037] A push rod 10 is fixedly connected to the middle part of the top of the rammer 2, and a push plate 21 is fixedly connected to the top of the push rod 10. The outer side of the push plate 21 is slidably connected to the chassis 1, and a mounting plate 13 is fixedly connected to the top wall of the chassis 1. A motor 12 is fixedly connected to one side of the mounting plate 13. The driving end of the motor 12 passes through the mounting plate 13 and is fixedly connected to an eccentric wheel 16. Starting the motor 12 drives the eccentric wheel 16 to rotate, so that the eccentric wheel 16 can push the push plate 21 below to move downward.

[0038] Slide rods 14 are fixedly connected at both ends of the chassis 1. The outer middle part of the slide rod 14 is slidably connected to both sides of the push plate 21. When the push plate 21 slides inside the chassis 1, the slide rod 14 can limit the push plate 21 to prevent the push plate 21 from tilting.

[0039] The two slide bars 14 are surrounded by springs 18 at their outer sides. One end of the two springs 18 is fixedly connected to the two sides of the bottom end of the push plate 21, and the other ends of the two springs 18 are fixedly connected to the two sides of the inner wall of the chassis 1. When the eccentric wheel 16 does not push the push plate 21 (i.e., when the eccentric wheel 16 rotates upward), the elastic force of the spring 18 will push the push plate 21 to move upward. When the push plate 21 moves upward to the top, the spring 18 itself will shake when it is stretched to the longest, thereby shaking the push plate 21, and the push plate 21 drives the rammer 2 to vibrate multiple times, so that the rammer 2 can produce multiple slight vibration impacts on the ground. When the spring 18 fully rebounds and extends to push the push plate 21 to move upward, the height that the push plate 21 can reach does not collide with the eccentric wheel 16 on the motor 12. As the eccentric wheel 16 continues to rotate, the eccentric wheel 16 will contact the upper end surface of the push plate 21, and move the push plate 21 downward, thereby impacting the ground.

[0040] A handle 11 is fixedly connected to one side of the chassis 1 , and the chassis 1 can be moved on the ground by pushing the handle 11 .

[0041] Support rods 19 are fixedly connected to both sides of the bottom end of the handle 11, and rollers 20 are rotatably connected to the bottom ends of the two support rods 19. The chassis 1 can be turned by holding the handle 11 and pressing it, and the chassis 1 can be slightly tilted with the support rods 19 as a fulcrum. When the rammer 2 vibrates downward, the vibration height of the rammer 2 is greater than the height of the wheels, so that the rammer 2 can touch the ground when vibrating.

[0042] Working principle: Start the motor 12 to drive the eccentric wheel 16 to rotate, thereby pushing the push plate 21 below and driving the top rod 10 and the rammer 2 to move downward, and as the eccentric wheel 16 rotates, the spring 18 will push the push plate 21 to drive the rammer 2 to move upward. The up and down movement of the rammer 2 can generate vibration to compact the ground. The handle 11 can be held to press. The chassis 1 can be turned by slightly tilting it with the support rod 19 as a fulcrum. Pushing the handle 11 can rotate the roller 20 so that the chassis 1 can move. The extension plate 4 is placed around the rammer 2, and then the fixing rod is pushed to make the T-block 17 slide inside the T-slot 6. The moving T-block 17 can push the two push blocks 3 on one side of the rammer 2 to enter the mounting seat 5 at the same time. The bolt 8 is then inserted into the mounting seat 5 and the mounting groove 7 in turn. When the bolt 8 enters the mounting groove 7, it pushes the two protrusions 15 inside the mounting groove 7 to slide out of the mounting groove 7 and enter the through hole 9. The bolt 8 is then tightened to fix the extension plate 4 to the four sides of the rammer 2, thereby adjusting the contact area between the rammer 2 and the foundation and adjusting the pressure of the rammer 2 to adapt to foundations of different geology. The area of ​​the rammer 2 is expanded so that the area of ​​the rammer 2 is larger than the area of ​​the upper chassis 1, so that when the rammer 2 tamps the ground close to the wall, the chassis 1 will not hinder the rammer 2 due to contact with the wall. By expanding the area of ​​the rammer 2, the area of ​​the foundation tamped by the tamping device can be increased at one time, thereby increasing the tamping speed.

[0043] 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 substitutions for some of the technical features therein.
