Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an assembled vibration isolation device. Background Art

[0002] As an active foundation reinforcement technology, the dynamic compaction method can make full use of and give play to the mechanical characteristics of the foundation soil itself, and is widely used in foundation reinforcement projects at home and abroad. The reinforcement mechanism of the dynamic compaction method is to repeatedly lift the rammer to a high place and let it fall freely, giving the foundation a huge impact energy, which propagates in the soil in the form of compression waves and shear waves, compressing the loose soil, causing the discharge of water and gas in the pores, and the soil particles tend to be closely arranged, thereby improving the bearing capacity of the soil. The vibration waves generated when the rammer contacts the ground will not only reinforce the soil, but also cause the vibration to be transmitted to the surroundings, causing adverse effects on the surrounding environment, such as damage to the function and structure of the building, interference with the operation of instruments and equipment, and harm to the physiological functions of livestock. Therefore, vibration isolation treatment is required during the dynamic compaction process.

[0003] At present, during the dynamic compaction process, the main means of vibration isolation is to dig a vibration isolation trench near the adjacent buildings (structures). The excavation depth and stability of the vibration isolation trench are affected by conditions such as soil properties, groundwater height, and site size, and the vibration isolation effect cannot be effectively guaranteed. With the continuous development of technology, during the actual construction process, engineering materials such as crushed stone and fly ash will be filled into the vibration isolation trench to improve its stability. However, the construction process is cumbersome, the construction period is long, and the construction labor intensity is high, which affects the construction progress. Utility Model Content

The toe 3 is fixedly arranged at the lower end of the shell 1, and the lower end of the toe 3 has a tip for breaking the ground. In the utility model, before the foundation is strongly compacted, the vibration isolation device can be inserted around the foundation by a pile driver to play a vibration isolation role. The shell 1, the vibration isolation plate 2 and the toe 3 are processed in the factory, and after the processing is completed, they are directly transported to the construction site for assembly and assembly. The toe 3 is fixedly connected to the shell 1 and inserted into the ground by a pile driver. Since the lower end of the toe 3 is a tip structure, it can be inserted more quickly. After the shell 1 and the toe 3 are inserted into the ground, the vibration isolation plate 2 is inserted into the cavity of the shell 1 to play a vibration isolation role. The vibration isolation device in the utility model is simple to assemble, convenient and quick to use, and can better improve the construction speed, thereby shortening the construction period.

[0025] like Figure 2As shown, in another embodiment, the shell 1 is a rectangular structure formed by two webs 4 and two ribs 5, and the cavity in the shell 1 is formed by the webs 4 and the ribs 5. The upper and lower ends of the two ribs 5 are respectively provided with connecting pieces 6, and the upper end surface of the connecting piece 6 located at the upper end of the ribs is flush with the upper end surface of the webs 4. The lower end surface of the connecting piece 6 located at the lower end of the ribs 5 is flush with the lower end surface of the webs 4. According to the design requirements, one shell or multiple shells are selected for assembly; when one shell 1 is used, the connecting piece 6 at the lower end of the ribs 5 is fixedly connected to the boot head 3; when multiple shells 1 are used for connection, the connecting pieces 6 on the adjacent two shells 1 are fixedly connected, so as to connect the adjacent two shells 1 together, and the boot head is fixedly connected to the shell 1 at the bottom layer, and it is inserted into the ground after assembly.

[0026] like Figure 3 As shown, in another embodiment, the connecting member 6 includes a first fixing plate 7, a second fixing plate 8 and a support plate 9, the first fixing plate 7 and the second fixing plate 8 are arranged in parallel, and the two ends of the support plate 9 are fixedly connected to the first fixing plate 7 and the second fixing plate 8 respectively, the first fixing plate 7 is fixedly connected to the rib plate 5, and the second fixing plate 8 is provided with a mounting hole for passing bolts, and a certain distance is left between the first fixing plate 7 and the second fixing plate 8 to facilitate the entry of a wrench to tighten the bolts.

[0027] like Figure 4 As shown, in another embodiment, the boot head 3 includes two side panels 10, the lower part of the side panels 10 is an inclined structure, and the lower ends of the two side panels 10 are fixedly connected to form a tip structure, specifically a "V"-shaped structure, the two side panels 10 are respectively located below the two webs 4, a chamber is provided between the two side panels 10, both sides of the chamber are connected to the outside, and the upper end of the chamber is connected to the cavity of the shell 1, and a connecting plate 11 is provided between the two side panels 10, and the connecting plate 11 and the second fixing plate 8 are fixedly connected by bolts.

[0030] Construction method: First, the entrance and exit sites are leveled, and the ground near the foundation where the vibration isolation device needs to be laid is leveled to facilitate the entry of equipment. The vibration isolation device is assembled according to the designed size. The pile driver inserts the assembled vibration isolation device into the ground. When inserting, the tip structure of the boot head faces the underground, which is convenient for the insertion of the vibration isolation device. After inserting to the designed depth, the vibration isolation plate is inserted into the cavity of the shell and filled up to play a role in vibration isolation. After the vibration isolation device is inserted, the foundation can be strongly compacted. Finally, after the construction is completed, the vibration isolation plate is first removed from the cavity of the shell, and then the grouting pipe is inserted into the cavity of the shell, and cement slurry is injected into the cavity through the grouting pipe. At the same time of grouting, the shell and the boot head are pulled out from the ground. Since the grouting pipe continuously injects cement slurry into the cavity of the shell, the cement slurry flows from the shell to the cavity of the boot head. In the process of continuous pulling out of the shell and the boot head, the cement slurry can fill the holes generated during the pull-out to avoid collapse.
