[0034] Reference Figure 1 and Figure 2 , a vibration isolation belt structure near a historical building, including a vibration isolation groove 6, which is arranged along the circumference of the building and surrounds the building. The inside of the vibration isolation groove 6 is defined as a first ground 61, and the outside of the vibration isolation groove 6 is defined as a second ground 62. Vibration is generally generated from the second ground 62. Cement mixing piles 65 are arranged in the first ground 61, and multiple cement mixing piles 65 are arranged at intervals along the circumference of the inner circle of the vibration isolation groove 6 to reinforce the first ground 61. The first ground 61 is separated from the second ground 62 by the vibration isolation groove 6, thereby blocking the vibration transmitted from the second ground 62 and reducing the impact of the vibration on the building. The cement mixing piles 65 can increase the stability of the first ground 61 and improve the earthquake resistance. At the same time, the soil of the first ground 61 is tightened to reduce the possibility of collapse of the first ground 61 during the construction of the vibration isolation groove 6.

[0035] The depth of the vibration isolation groove 6 is 2.5 to 4 meters, preferably 3 meters, which can cut off most of the vibration transmission and improve the stability of the first ground 61; the width of the vibration isolation groove 6 is 1-3 meters, preferably 2.5 meters.

[0036] According to the vibration isolation belt structure adjacent to the historical building of this embodiment, a reinforcement component is provided on the first ground 61, and the reinforcement component is connected to the wall of the building. There are two groups of reinforcement components to reinforce the inner and outer sides of the wall respectively.

[0037] Specifically, the reinforcement assembly includes a keel 63, a diagonal brace 631 and a supporting concrete foundation 632. The supporting concrete foundation 632 is cast on the ground. The keel 63 is vertically arranged and fits the wall to support the wall. One end of the diagonal brace 631 is hinged to the keel 63, and the other end is hinged to the supporting concrete foundation 632. At least two diagonal braces 631 are arranged on each group of keels 63 in the vertical direction to provide stable support for the keel 63. The diagonal brace 631 can use a damping rod to absorb vibration and improve shock absorption performance.

[0038] In addition, a hanging net 64 is provided on the side wall of the vibration isolation groove 6 close to the building, and fixing nails are provided inside the side wall of the vibration isolation groove 6 close to the building, and the fixing nails are used to fix the hanging net 64. After the hanging net 64 is fixed, concrete is sprayed on the side wall of the vibration isolation groove 6 close to the building to form a concrete slope protection layer, thereby further strengthening the side of the first ground 61 and reducing the possibility of landslide.

[0039] In order to further improve the strength of the concrete slope protection layer, screws are connected inside the cement mixing pile 65 , and the screws are connected to the hanging net 64 .

[0040] Working principle: The first ground 61 is separated from the second ground 62 by the vibration isolation groove 6, thereby blocking the vibration transmitted from the second ground 62 and reducing the impact of the vibration on the building. The cement mixing pile 65 can increase the stability of the first ground 61 and improve the earthquake resistance. At the same time, the soil of the first ground 61 is tightened to reduce the possibility of collapse of the first ground 61 during the construction of the vibration isolation groove 6. The walls of the building are reinforced by reinforcement components to reduce the possibility of damage to the building caused by vibration. The concrete slope protection layer is formed by hanging the net 64 and spraying concrete, and the first ground 61 is further strengthened to reduce the loosening of the soil layer and protect the building.

[0042] S1. Reinforce the wall of the building by using the reinforcement assembly. During the reinforcement, first pour the supporting concrete foundation 632 layer, then install the keel 63 on the wall, and finally install the diagonal brace 631 between the keels 63.

[0043] S2. Draw a line around the building on the ground, mark the position where the cement mixing pile 65 needs to be driven, and mark the range of the vibration isolation groove 6.

[0044] S3, carrying out the construction of cement mixing pile 65.

[0045] S4, after the cement mixing pile 65 solidifies, dig out the vibration isolation groove 6 along the marked range of the vibration isolation groove 6. Constructing the cement mixing pile 65 first is convenient for reinforcing the soil layer of the first ground 61, reducing the possibility of collapse of the first ground 61 when digging the vibration isolation groove 6.

[0046] S5, laying a hanging net 64 on the side wall of the vibration isolation groove 6, punching holes on the side wall of the vibration isolation groove 6 to drive in fixing nails, and then fixing the hanging net 64 by the fixing nails. When punching holes, the side wall of the vibration isolation groove 6 is punched by the punching device 7.

A working plate 727 is fixedly connected to the drilling hole, the working plate 727 is threadedly connected to the screw 724, one end of the guide rod 725 is fixedly connected to the vertical moving plate 722, and the other end passes through the working plate 727 to provide guidance for the working plate 727. A support spring 726 is sleeved on the guide rod 725, one end of the support spring 726 abuts against the working plate 727, and the other end abuts against the vertical moving plate 722, so as to increase the supporting force on the working plate 727. The support spring 726 can be a compression spring.

[0050] During operation, the moving wheels facilitate the movement of the moving frame 71. When it moves to the corresponding position, the first linear module 721 drives the vertical moving plate 722 to move to the corresponding height. Then the drilling machine 73 is started, and the first motor 723 is also started, driving the drilling machine 73 to move toward the side wall of the vibration isolation groove 6 to drill holes.

[0051] Specifically, refer to Figures 4 to 6The spraying device 8 includes a frame 81, and two moving tracks 811 are installed under the frame 81 so that the frame 81 can move on the dirt road. The frame 81 is also fixedly connected with a mixing tank 82, a solid delivery pump 83, a second linear module 84 and a support rail 85. There are two mixing tanks 82, and the output ends of the two mixing tanks 82 are connected to the same three-way valve, and the other interface of the three-way valve is connected to the input end of the solid delivery pump 83. The use of two mixing tanks 82 can make it possible for the fixed delivery pump to always have mixed concrete to be extracted. The output end of the solid delivery pump 83 is connected to a nozzle, and a nozzle 831 is connected to the nozzle. The nozzle 831 is arranged toward the side wall of the vibration isolation tank 6 so as to spray concrete toward the side wall of the vibration isolation tank 6. A bracket 87 is slidably connected to the support rail 85, and a fixing ring 871 for fixing the nozzle 831 is provided on the bracket 87. The movable end of the second linear module 84 is connected to the bracket 87 to drive the bracket 87 to move along the length direction of the moving track 811. The bracket 87 is also provided with an angle adjustment component 88, and the movable end of the angle adjustment component 88 is connected to the fixing ring 871, so that the fixing ring 871 swings, and then the spray head 831 swings up and down, so as to spray concrete in sequence along the vertical direction.

[0052] More specifically, the spray head 831 is inserted into the fixing ring 871, and the fixing ring 871 is threadedly connected with a fixing bolt 872, and the fixing bolt 872 is suitable for locking the spray head 831. A rotating shaft 873 is fixedly connected to the side wall of the fixing ring 871, and the rotating shaft 873 is rotatably connected to the bracket 87. A sleeve 874 is sleeved on the rotating shaft 873, and the sleeve 874 can rotate relative to the rotating shaft 873. The sleeve 874 is also rotatably connected to the bracket 87. A locking bolt 875 is threadedly connected to the sleeve 874, and the locking bolt 875 is used to lock the sleeve 874 with the rotating shaft 873.

[0053] The angle adjustment assembly 88 includes a third linear module 881, an adjustment rod 882, a rack 883 and a gear 884. The third linear module 881 is fixedly connected to the bracket 87. The movable end of the third linear module 881 is fixedly connected to the adjustment rod 882. The gear 884 is coaxially fixed to the sleeve 874. The rack 883 slides on the bracket 87, and the gear 884 is meshed with the rack 883. A clamping rod 8851 slides in the vertical direction on the adjustment rod 882. A positioning groove for inserting the clamping rod 8851 is provided at the bottom of the adjustment rod 882. A plurality of positioning grooves are provided along the length direction of the rack 883. A stopper 8852 is threadedly connected to the bottom of the clamping rod 8851. A tension spring 8853 is connected between the stopper 8852 and the bottom of the adjustment rod 882 so that the clamping rod 8851 is located in the positioning groove under normal conditions. The clamping rod 8851 is inserted into different positioning slots to adjust the moving distance of the rack 883, thereby adjusting the swing angle of the nozzle 831. The sleeve 874 and the rotating shaft 873 can rotate relative to each other, thereby adjusting the initial spraying angle of the nozzle 831.

[0054] During operation, the moving crawler 811 drives the frame 81 to move, and the solid delivery pump 83 extracts the mixed concrete from the mixing tank 82 and sprays it from the nozzle 831. At this time, the movable end of the third linear module 881 drives the adjustment rod 882 to move, the adjustment rod 882 drives the rack 883 to rotate, the rack 883 drives the gear 884 to rotate, and the gear 884 drives the sleeve 874 to rotate, and then drives the fixed ring 871 and the nozzle 831 to swing, so that the nozzle 831 sprays a straight line in the vertical direction. At the same time, the movable end of the second linear module 84 drives the bracket 87 to move in the opposite direction of the movement of the frame 81, and the moving speed is the same as the moving speed of the frame 81, so that the concrete sprayed by the nozzle 831 is a straight line. When the movable end of the third linear module 881 moves to the head in one direction, the movable end of the second linear module 84 is quickly reset. At this time, the movable end of the third linear module 881 moves in the opposite direction, and the second linear module 84 continues to move in the opposite direction of the frame 81, so that the nozzle 831 sprays along an S-shaped curve, thereby making the sprayed concrete evenly form a surface.
