[0027] See Figure 1 , Figure 2 This application provides a vibration reduction and reinforcement structure for a utility tunnel construction under a road, including a plurality of first steel pipes 3 disposed in the soil between the road 1 and the utility tunnel 2; each first steel pipe 3 has a first vibration reduction cavity 31 and a first grouting cavity 32, and a first grouting hole 36 connected to the first grouting cavity 32 is provided on the first steel pipe 3. The first vibration reduction cavity 31 is provided with vibration reduction fluid, and the first grouting cavity 32 is provided with a first grouting body. The first grouting body is bonded to the soil around the first steel pipe 3 through the first grouting hole 36.

[0028] The pipe gallery construction underpass road vibration reduction and reinforcement structure provided by the embodiment of the application is characterized in that a plurality of first steel flower pipes 3 are arranged in the soil between the road 1 and the pipe gallery 2, and are used for vibration reduction and reinforcement. Specifically, a first damping cavity 31 is arranged in the first steel flower pipe 3, and damping liquid is arranged in the first damping cavity 31. When a vehicle is driving on the road 1, the vibration load generated by the vehicle is transmitted downward to the first steel flower pipe 3, and then is transmitted to the damping liquid in the first damping cavity 31 through the first steel flower pipe 3, so that the damping liquid is vibrated to consume the vibration load generated by the vehicle, thereby reducing the transmission of the vibration load to the construction position of the pipe gallery 2. A first grouting cavity 32 is arranged in the first steel flower pipe 3. After the first steel flower pipe 3 is inserted into the soil, the slurry is injected into the first grouting cavity 32 by using a grouting machine. During the process, the slurry is injected into the soil around the first steel flower pipe 3 through the first grouting hole 36 to form a grouting curtain. After the slurry is solidified, the first grouting body is formed. The first grouting body is used to cement the first steel flower pipe 3 and the soil around the first steel flower pipe 3, so as to achieve the effect of reinforcing the soil between the road 1 and the pipe gallery 2. In this way, the stress loss caused by underground excavation can be reduced. Furthermore, the effects of vibration reduction and reinforcement are achieved at the same time, the settlement effect is avoided, and the damage to the road surface caused by the uneven settlement of the soil during the pipe gallery excavation construction is prevented. The pipe gallery construction underpass road vibration reduction and reinforcement structure provided by the embodiment of the application does not involve the use of large mechanical equipment, and the disturbance to the roadbed soil during the construction process is small. Therefore, the construction can be carried out without affecting the driving.

[0029] The number of the first steel flower pipes 3 should be set according to the actual situation, and is not specifically limited here.
