Background Art

[0002] With the rapid development of industry and the diversification of industrial equipment, many problems have also been brought about. The most significant of these is the impact of vibration caused by the operation of industrial equipment on surrounding buildings. In recent years, the vibration disasters caused by industrial vibrations on surrounding houses have become increasingly serious, seriously damaging the safety and property of the surrounding people. Therefore, it is necessary to set up reasonable and feasible vibration reduction and isolation measures, which is of great significance to the protection of surrounding buildings.

[0003] At present, there are many vibration reduction and isolation technologies, mainly focusing on equipment foundation vibration reduction and equipment built-in vibration absorbers. However, using this method for existing industrial equipment will result in high costs, affect industrial production, and some vibrations will still be transmitted to surrounding buildings.

[0004] Therefore, there is a need for a construction method for a vibration reduction and isolation system that can effectively reduce the vibration damage caused by industrial vibration to surrounding houses while not affecting industrial production. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a construction method for a vibration reduction and isolation system that reduces the impact of industrial vibration on surrounding buildings in view of the deficiencies of the above-mentioned prior art. This method changes the propagation path of the vibration wave generated by the industrial vibration source and consumes the energy of the vibration wave by setting a vibration isolation ditch for pouring improved asphalt hemp knife mixture between the industrial vibration source and the building, thereby greatly improving the vibration reduction and isolation system's energy consumption efficiency, effectively reducing the vibration disasters caused by industrial vibration to surrounding houses, and at the same time not affecting industrial production. It has groundbreaking engineering significance and has practical value with simple construction process and low cost.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings, characterized in that the method comprises the following steps:

[0007] Step 1: Determine the size of the industrial vibration source foundation, the location of related underground pipelines and the location of surrounding buildings;

[0008] Step 2: Based on the size and position obtained in step 1, a vibration isolation trench is designed between the industrial vibration source and the surrounding buildings, while avoiding related underground pipelines, and obtaining the size data of the vibration isolation trench;

[0009] Step 3: excavate the soil around the foundation in a manner with less disturbance according to the size data of the vibration isolation trench obtained in step 2 to obtain the vibration isolation trench;

[0010] Step 4: remove the loose soil inside the vibration isolation trench obtained in step 3, and clean up the soil residue to obtain the vibration isolation trench to be filled;

[0011] Step 5, heating the modified asphalt until it is completely melted and presents a uniform liquid state, then slowly and evenly adding the hemp blades and heating and stirring, so that the hemp blades are evenly distributed in the modified asphalt, and obtaining a modified asphalt hemp blade mixture in which the hemp blades are completely coated with the modified asphalt;

[0012] Step 6: slowly pour the improved asphalt hemp blade mixture obtained in step 5 into the vibration isolation trench to be filled in step 4 until one layer is filled, and vibrate the poured improved asphalt hemp blade mixture with a vibrating rod, and move slowly during the vibration process to expel the air in the improved asphalt hemp blade mixture, and then repeat the above process to pour the next layer until the vibration isolation trench is filled with the improved asphalt hemp blade mixture;

[0013] Step 7: Allow the modified asphalt hemp knife mixture filled in the vibration isolation trench in step 6 to cool and solidify naturally to prevent it from being damaged by external forces or contacting water before it is completely solidified;

[0014] Step 8: After the improved asphalt hemp blade mixture in step 7 is naturally cooled and solidified, a rubber cover is used to close the vibration isolation trench to obtain a vibration reduction and isolation system that reduces the impact of industrial vibration on surrounding buildings.

[0015] The present invention determines the size of the industrial vibration source foundation and the position of the surrounding buildings to determine the impact range of the industrial vibration source on the surrounding buildings, thereby determining the position and size of the vibration isolation ditch, ensuring that the vibration isolation ditch completely blocks the vibration impact of the industrial vibration source on the surrounding buildings, and prevents the relevant underground pipelines from being damaged during the construction of the vibration reduction and isolation system by determining the position of the relevant underground pipelines, and prevents the soil under the vibration source foundation from being disturbed by excavation in a manner with less disturbance, and makes the vibration isolation ditch flat and solid by removing the loose soil inside the vibration isolation ditch and cleaning up the soil residue, and heating the improved asphalt until it is completely melted and presents a uniform liquid state, so as to facilitate the uniform distribution of hemp blades in the improved asphalt, enhance the waterproof performance of the improved asphalt hemp blade mixture, and prevent the shortcoming that the toughness of the hemp blade fiber is reduced under the long-term action of rainwater, so that the hemp blade forms an effective bonding structure in the improved asphalt, and the flexibility of the improved asphalt is combined with the bonding effect of the hemp blade, thereby increasing the improved asphalt hemp blade mixture. The toughness and crack resistance of the material are improved, and a modified asphalt hemp knife mixture in which the hemp knife is completely wrapped by the improved asphalt is obtained. The modified asphalt hemp knife mixture is poured layer by layer in the vibration isolation trench and vibrated. The vibration process moves slowly to expel the air in the modified asphalt hemp knife mixture, thereby ensuring that each layer of the modified asphalt hemp knife mixture has a dense structure and the effect of vibration reduction and isolation is improved. In addition, care should be taken to avoid voids and gaps during pouring. The modified asphalt hemp knife mixture should be tightly bonded to both sides of the vibration isolation trench. In the process of waiting for the modified asphalt hemp knife mixture to cool and solidify naturally, it is prevented from being damaged by external forces or contacting with water before it is completely solidified. The quality of the modified asphalt hemp knife mixture is guaranteed and the effect of vibration reduction and isolation is improved. The vibration isolation trench is closed by using a rubber cover to protect the modified asphalt hemp knife mixture, prevent the damage to the modified asphalt hemp knife mixture by sunlight and rain, and prevent the entry of external debris, thereby obtaining a vibration reduction and isolation system that reduces the impact of industrial vibration on surrounding buildings.

[0016] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the size of the industrial vibration source foundation in step 1 includes the width of the industrial vibration source foundation and the buried depth of the foundation. The present invention determines the impact range of the industrial vibration source on the surrounding buildings by determining the width of the base of the industrial vibration source and the buried depth of the base, which facilitates the subsequent construction of the vibration isolation trench.

[0017] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the dimension data of the vibration isolation trench in step 2 include: the distance between the vibration isolation trench and the edge of the industrial vibration source foundation is 3m to 20m, the depth of the vibration isolation trench is the buried depth of the base plus 1m to 5m, and the width of the vibration isolation trench is 0.3m to 3m. The present invention controls the dimension data of the vibration isolation trench, controls the distance between the vibration isolation trench and the edge of the industrial vibration source foundation, prevents the excavation of the vibration isolation trench from disturbing the soil under the vibration source foundation, and avoids the influence of the dynamic response enhancement zone. The reasonable dimension data of the vibration isolation trench can hinder the propagation of vibration waves to the maximum extent and ensure that the vibration reduction and isolation system has the best vibration reduction and isolation effect.

[0018] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the less disturbing method in step 3 is manual excavation. The present invention adopts manual excavation to prevent the soil under the foundation of the vibration source from being disturbed.

In the present invention, when only one side of the industrial vibration source is adjacent to the surrounding buildings, a vibration isolation trench with a concave structure is designed, so that the vibration waves generated by the industrial vibration source cannot bypass the vibration isolation trench and directly affect the building, thereby reducing costs while ensuring the vibration reduction and isolation effect. When two or more sides of the industrial vibration source are adjacent to the surrounding buildings, a vibration isolation trench with a round-shaped structure is designed, and the industrial vibration source is surrounded by the vibration isolation trench, so that the vibration waves generated by the industrial vibration source cannot bypass the vibration isolation trench and directly affect the building, thereby ensuring the vibration reduction and isolation effect.

The present invention controls the mass ratio of the modified asphalt and the hemp blade, so that the modified asphalt hemp blade mixture has a low elastic modulus and good damping characteristics, and has the best vibration reduction and isolation effect. At the same time, it also ensures that the hemp blade is evenly distributed in the modified asphalt, enhances the waterproof performance of the modified asphalt hemp blade mixture, prevents the deficiency of the hemp blade fiber toughness characteristics being reduced under the long-term action of rainwater, and enables the hemp blade to form an effective bonding structure in the modified asphalt, so that the flexibility of the modified asphalt and the bonding effect of the hemp blade are combined, and the toughness and crack resistance of the modified asphalt hemp blade mixture are increased.

General asphalt will become soft and thin at high temperatures, and its fluidity will increase. At low temperatures, it will become hard and brittle and is not suitable for use in the present invention. Therefore, the present invention uses modified asphalt with high temperature stability and low temperature crack resistance, which is suitable for high and low temperature environments, improves the effect of vibration reduction and isolation, and the life of the vibration reduction and isolation system, uses dry and non-rotten hemp blades to ensure that the hemp blade fibers are tough, and by controlling the fiber length of the hemp blades, an effective binding structure is formed to improve the toughness and crack resistance of the modified asphalt hemp blade mixture, and prevents the fibers from being too long, which are easy to entangle and knot during mixing and construction, which is not conducive to uniform distribution in the modified asphalt, and the fibers are too short to form an effective binding structure.

[0022] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the temperature of heating and stirring in step 5 is 150° C. to 180° C. The present invention controls the temperature of heating and stirring to make the modified asphalt in a liquid state, thereby ensuring that the hemp blades are evenly distributed in the modified asphalt, and obtaining a modified asphalt hemp blade mixture in which the hemp blades are completely wrapped by the modified asphalt.

[0023] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the improved asphalt hemp blade mixture in step 5 is used within 1 to 2 hours after it is made. The present invention ensures that the improved asphalt hemp blade mixture has the best vibration reduction and isolation effect by controlling the use time after the improved asphalt hemp blade mixture is made.

[0024] The above-mentioned construction method of a vibration reduction and isolation system for reducing the impact of industrial vibration on surrounding buildings is characterized in that the thickness of the layer in step 6 is 15cm to 20cm. The present invention controls the thickness of each layer to ensure that the modified asphalt hemp knife mixture in the vibration isolation ditch is densely stacked, and has the best vibration reduction and isolation effect.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The present invention arranges a vibration reduction and isolation system between the industrial vibration source and the building, that is, a vibration isolation ditch of a modified asphalt-hemp mixture is poured, so as to change the propagation path of the vibration wave generated by the industrial vibration source, so that the vibration wave propagated to the surrounding areas by the industrial vibration source in the underground medium is reflected by a part of the vibration wave and refracted by the obvious medium mutation interface of the vibration isolation ditch. Then, the modified asphalt and hemp fiber inside the modified asphalt-hemp mixture will cause certain deformation and friction, thereby consuming the energy of the vibration wave, greatly improving the vibration reduction and isolation system's energy consumption efficiency, effectively reducing the vibration disaster of industrial vibration to surrounding houses, and at the same time not affecting industrial production, having groundbreaking engineering significance, and having practical value of simple construction process and low cost.

[0027] 2. The improved asphalt hemp blade mixture of the present invention has a low elastic modulus and good damping properties. When subjected to vibration, the improved asphalt and hemp blade fibers inside it will undergo certain deformation and friction, thereby consuming the energy of the vibration wave and reducing the impact of the vibration source on surrounding houses. At the same time, the improved asphalt hemp blade mixture can operate normally in high and low temperature and underground humid environments.

The improved asphalt hemp mixture filled in the vibration isolation trench of the present invention has different physical properties from the surrounding soil, so that the energy of the vibration wave is dispersed and consumed during the propagation process. The improved asphalt hemp mixture is filled in the vibration isolation trench, which increases the damping and accelerates the vibration attenuation of the vibration wave during the vibration of the structure, thereby reducing the vibration energy transmitted from the vibration source to the surrounding buildings.

[0029] 4. The present invention fills the vibration isolation trench with improved asphalt hemp knife mixture, which has the characteristics of simple construction process and low cost, and has great advantages in projects with high cost control requirements.
