[0002] In recent years, with the development of urbanization construction, artificial vibrations caused by traffic, blasting and construction can be spread to the surrounding through the roadbed and soil medium, further transmitted to the building, and then cause indoor vibration and noise, which may cause structural damage and affect the normal life of residents along the line. At present, the most common method to weaken the propagation of vibration is to set a wave barrier between the vibration source and the protected building, including empty trench and filled trench, pile and wave barrier plate. The wave barrier plate is often buried under the power machine, track and roadbed to reduce the propagation of vibration. However, the traditional wave barrier plate is restricted by the soil cutoff frequency, and only when the vibration source frequency is lower than the soil cutoff frequency, the wave barrier plate can play a vibration isolation effect, and the vibration isolation frequency band is narrow; and the traditional wave barrier plate needs to be buried by excavating the foundation, which will obviously affect the vehicle operation, and the construction process will also cause secondary environmental vibration pollution problem.

[0072] In this embodiment, the characteristic frequency equation is as follows:

The wave resistance plate burial depth determines the excavation depth of the cell hole, and the wave resistance plate thickness is less than the wave resistance plate burial depth. The distance from the top of the wave resistance plate to the ground plus the wave resistance plate thickness is the wave resistance plate burial depth; as shown in the wave resistance plate side view or front view, the wave resistance plate thickness determines the thickness of the wave resistance plate in the ground.

[0094] B235, excavating the cell hole according to the excavation depth of the cell hole, the excavation radius of the cell hole, the arrangement form of each cell hole in the wave resistance plate and the periodic distance between adjacent cell holes in the wave resistance plate.

[0095] B24, for any cell hole, arranging a hollow grouting pipe in the cell hole according to the filler layer radius; the hollow grouting pipe is provided with a through hole on the curved surface, and the height of the through hole is consistent with the wave resistance plate thickness. As shown in Figure 9 ​As shown, the through holes of the hollow grouting pipe refer to the holes formed in a certain height range of the pipe, and the bottom side of the pipe is closed. Thus, through subsequent grouting operation, the Figure 10 As shown, the periodic cells with a certain thickness are formed in a certain height.

[0096] B25, according to the initial grouting pressure, the hollow grouting pipe is injected with the cladding layer material, so that the cladding layer material fills the space between the cell hole and the hollow grouting pipe, and forms a cladding layer on the periphery of the hollow grouting pipe.

[0097] B26, according to the initial grouting pressure, the outer diameter of the extrusion layer and the formation parameters, the reaming grouting pressure is determined; the relationship among the reaming grouting pressure, the outer diameter of the cladding layer and the outer diameter of the extrusion layer is as shown in Figure 11 As shown, the reaming grouting pressure in this embodiment is determined according to the following formula:

[0098]

[0099]

[0100]

[0101] wherein p is the reaming grouting pressure, p0 is the initial grouting pressure, a u is the outer diameter of the cladding layer, r p is the outer diameter of the extrusion layer, c0 and are the effective cohesion and effective internal friction angle of the soil, respectively, which are obtained by CU test and simultaneously by pore water pressure measurement method to obtain the effective internal friction angle and cohesion; c t and are the unified cohesion and unified internal friction angle obtained by unified strength theory; u a is the pore gas pressure, which is measured on site by pore gas pressure sensor; u w is the pore water pressure, which is measured on site by pore water pressure gauge; u s and c s are the matrix suction and soil adsorption strength, respectively; is the internal friction angle related to the matrix suction, which can be obtained by unsaturated soil shear test method; b is the unified strength parameter, and the value range is 0-1.

[0102] B27, according to the reaming grouting pressure, the hollow grouting pipe is injected with the cladding layer material, so that the cladding layer extrudes the surrounding soil, and forms an extrusion layer between the cladding layer and the surrounding soil.

[0103] B28, according to the filling material grouting pressure, the hollow grouting pipe is injected with the filling layer material, and a periodic cell is obtained.

[0104] Repeat the above steps B24-B28 to construct all periodic cells to obtain a periodic wave barrier plate comprising a plurality of periodic cells.

[0105] In addition to the above, the present embodiment illustrates the wave barrier plate construction method provided by the present embodiment through a specific example:

[0106] The first step is grouting drilling construction. According to the determined wave barrier plate construction parameters, a geological drilling machine is used to drill through the pavement subgrade to the required wave barrier plate arrangement depth. The initial hole diameter can be generally set to 90-110 mm, and the drilling verticality is ensured to be <1%. To prevent deformation of the pavement, it is required that the periodic constant satisfies a≥2r p .

[0107] The second step is hollow grouting pipe embedding and orifice grouting device. The orifice grouting device can use a mixer. When the gap between the hollow grouting pipe and the grouting hole is large, a rubber ring is needed to be caught above the side hole, and then cement slurry or cement water glass slurry is used for sealing and fixing.

[0108] The third step is to use high-pressure jet grouting after the hollow grouting pipe embedding and orifice grouting device described in the second step are embedded for 1-3 days. To accelerate the solidification of the slurry, a double-liquid jet grouting method of spraying cement first and then water glass can be used.

[0109] The fourth step is to use the orifice grouting device to seal the orifice for static pressure grouting after the high-pressure jet grouting described in the third step is completed. The static pressure grouting can expand the grouting range of the slurry. To prevent the solidification of the jet grouting slurry, a relatively dilute slurry and a relatively low grouting pressure are used at the beginning of the static pressure grouting, and then the slurry concentration and the grouting pressure are gradually increased until the designed grouting amount and grouting pressure are reached.

[0110] The fifth step is hole sealing and orifice treatment. After the static pressure grouting is completed, the orifice needs to be closed and treated if the grouting hole is gushing. At the same time, to prevent rainwater infiltration, a slurry with anti-seepage and durability needs to be poured into the orifice.

[0111] In addition, the following design references are provided in this example:

[0112] In order to ensure that the wave barrier plate can achieve ideal vibration isolation effect under different soil conditions and different vibration conditions, the depth and geometric size reference value range of the wave barrier plate are given according to the conservative case (only the reference value range, the actual project can be valued according to the vibration isolation required):

[0113] Depth from the pavement, i.e. wave barrier plate depth (H): (0.01-0.06)λ R

[0114] Wave barrier plate thickness (h): (0.04-0.09)λR

[0115] Wave resistance plate length (l): needs to be further determined according to the target area range.

[0116] Wave resistance plate width (w): consistent with the road surface width.

[0117] Wherein: λ R is the main Rayleigh wave wavelength.

[0118] In this embodiment, by using the wave resistance plate construction parameter determination method of example 1, the parameter groups of the wave resistance plate with different structure parameters and material parameters are simulated, the barrier frequency range of each parameter group is obtained, and the intersection with the frequency range of the vibration wave propagating in the target area soil is calculated to determine the optimal wave resistance plate parameter group in each wave resistance plate parameter group. And in the subsequent wave resistance plate construction process, the wave resistance plate construction process is scientifically and effectively guided, and it is ensured that the constructed wave resistance plate can fully isolate the propagation of vibration waves in the soil.
