Description

Technical Field

[0001] The utility model relates to the technical field of sound barriers, and more specifically, to a sound barrier infrastructure structure for strong wind areas. Background Art

[0002] A sound barrier, also known as a soundproof wall or noise barrier, is a structure specifically designed to reduce, block, or reflect the transmission of sound. They are typically installed between noise sources such as roads, railways, airports, and industrial areas, and areas to be protected (such as residential areas, schools, and hospitals) to mitigate the effects of noise pollution. The sound barrier's infrastructure, primarily the ground support, is a critical component in ensuring the stability and durability of the entire system.

[0003] During the construction of the foundation structure of the sound barrier in the prior art, a galvanized steel pipe is usually first driven into the ground so that the end of the galvanized steel pipe extends out of the ground, and a steel cage is set on the ground so that the end of the galvanized steel pipe is located inside the steel cage. An anchor bolt flange is then set inside the steel cage, and a formwork is set around the steel cage before pouring concrete. However, even if the end of the steel pipe is located inside the steel cage, when encountering strong winds, the bonding strength between the concrete and the steel pipe is not sufficient to resist the strong lateral force, which is particularly obvious under the action of strong winds. It is not sufficient to resist the force of strong winds on the foundation structure of the sound barrier in a strong wind environment. Utility Model Content

DETAILED DESCRIPTION

[0028] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Refer to the instruction manual Figures 1 to 2 A sound barrier foundation structure for strong wind areas, comprising: a prestressed pipe pile 1, the prestressed pipe pile 1 being inserted below the ground, a steel cage 2 being inserted into the hollow portion of the top of the prestressed pipe pile 1, a cap 3 being cast with concrete at the top of the prestressed pipe pile 1, the hollow portion of the prestressed pipe pile 1 and the cap 3 being integrally cast with concrete, the top of the steel cage 2 extending into the cap 3, a thin steel plate 21 being installed at the bottom of the steel cage 2 for receiving concrete, and an anchor bolt flange 4 being pre-embedded in the cap 3;

[0030] A sound barrier column 5 is installed on the base 3 through bolts and the anchor bolt flange 4, and a sound barrier 6 is installed on the side of the sound barrier column 5.

[0031] It should be noted that holes are drilled in the ground in advance by pile foundation construction machinery, and then the prestressed pipe piles 1 are inserted into the pre-drilled holes by hoisting machinery. The steel cage 2 is welded with spiral steel wire and steel bars. The spiral welding method can enhance the structural integrity of the steel cage 2, making the steel cage 2 tighter and more stable, thereby improving the tensile strength of the steel cage 2, reducing the fragility of the welding points, and increasing the durability and reliability of the structure.

[0032] The specific implementation scenario is as follows: first, a hole is drilled in the ground in advance by pile foundation construction machinery, and then the prestressed pipe pile 1 is inserted into the pre-drilled hole by a hoisting machine, and then the steel cage 2 is inserted into the hollow part of the top of the prestressed pipe pile 1, and then a template is set on the top of the prestressed pipe pile 1, and an anchor bolt flange 4 is set, and then concrete is poured, and the base 3 is poured through the enclosed template, and the top of the steel cage 2 is extended into the base 3, and the hollow part of the prestressed pipe pile 1 and the base 3 concrete are cast integrally. By adopting the prestressed pipe pile 1 with a higher bearing capacity and good stability, the application of its prestress can increase the bending resistance of the pipe pile, so that the pipe pile is less deformed under the action of wind load, thereby ensuring the stability of the entire structure, inserting the steel cage 2 into the hollow part of the top of the prestressed pipe pile 1, and setting a thin steel plate 21 at the bottom, The connection strength between the prestressed pipe pile 1 and the pedestal 3 can be enhanced. The steel cage 2 provides longitudinal and transverse reinforcement, and the thin steel plate 21 can prevent leakage from the bottom during concrete pouring, ensuring that the concrete and the prestressed pipe pile 1 form a solid whole, thereby improving the rigidity of the structure. The hollow part of the prestressed pipe pile 1 is cast integrally with the pedestal 3 concrete, so that there is no obvious joint between the prestressed pipe pile 1 and the pedestal 3, forming a continuous concrete body, thereby enhancing the shear and pull-out resistance of the overall structure, which is particularly effective in resisting horizontal wind loads. In addition, by pre-embedding the anchor bolt flange 4 in the pedestal 3, the sound barrier column 5 can be firmly connected to the foundation to form a whole, ensuring that the sound barrier column 5 will not fall off from the foundation even under strong wind conditions, thereby enhancing the overall structure's resistance to wind force.

[0033] In the above technical solution, the main function is to enhance the ability of the basic structure to resist wind force. The current sound barrier basic structure not only requires the basic structure to resist wind force, but also requires the sound barrier 6 to resist wind force. The sound barrier 6 in the prior art only sets the top end of the sound barrier 6 as an arc surface to improve the flow of airflow and reduce the direct impact of wind on the sound barrier 6. However, in a strong wind environment, its resistance to wind force is still insufficient. For this reason, the utility model proposes an air guide mechanism 7 to solve the above problem.

[0034] For details, please refer to the attached manual. Figure 3 and Figure 4 The top of the sound barrier 6 is set as an arc surface, and an air guide mechanism 7 is set on the sound barrier 6. The air guide mechanism 7 is used to disperse and guide the wind blowing towards the sound barrier 6. The interior of the sound barrier 6 is hollow, and the top of the sound barrier 6 is open. The air guide mechanism 7 includes a number of ventilation holes 71. The several ventilation holes 71 are all opened on the side of the sound barrier 6. Several air guide plates 72 are set in the sound barrier 6, and the air outlet ends of the several ventilation holes 71 point to the corresponding air guide plates 72.

[0035] It should be noted that in a strong wind environment, when the wind blows towards the sound barrier 6, part of the wind will enter the sound barrier 6 through several ventilation holes 71. In this process, the pressure of the wind when it blows directly towards the sound barrier 6 can be dispersed through several ventilation holes 71, and when the wind enters the sound barrier 6, the wind entering the sound barrier 6 through the corresponding ventilation holes 71 will blow towards the corresponding wind guide plates 72, and the wind entering the sound barrier 6 will be further dispersed by several wind guide plates 72.

[0036] Further, refer to the instructions attached Figure 4 The wind guide plate 72 is set at an angle, and the inner wall of one side of the sound barrier 6 is set as an inclined surface, and a number of wind guide grooves 73 are opened on its inner wall.

[0037] It should be noted that since the wind guide plate 72 is set at an angle, the wind blowing towards the wind guide plate 72 will flow in the inclined direction of the wind guide plate 72 according to the inclined direction of the wind guide plate 72, and blow towards the inclined inner wall of the sound barrier 6, and then pass through a number of wind guide grooves 73 on the inner wall to discharge the wind through the top opening of the sound barrier 6, so as to disperse the flow of the airflow and reduce the direct impact of the wind on the sound barrier 6.

[0038] Further, refer to the instructions attached Figure 4 The air guide plate 72 is provided with a plurality of vents 721 , and the diameter of the air inlet of the vent 721 is smaller than the diameter of the air outlet.

[0039] It should be noted that when the wind flows on the surface of the wind guide plate 72, part of the wind can be blown toward the inclined inner wall of the sound barrier 6 through the wind guide plate 72. However, since the diameter of the air inlet of the vent 721 is smaller than the diameter of the air outlet, the wind will be reduced when passing through the vent 721, which can further reduce the impact of the wind and further enhance the sound barrier 6's resistance to wind.

[0040] In the above technical solution, the main issue is the ability to resist strong winds. However, strong winds are usually accompanied by heavy rainfall, and the top of the sound barrier 6 is set to an opening. During heavy rainfall, rainwater will enter the interior of the sound barrier 6 through the opening at the top of the sound barrier 6. However, when wind enters the sound barrier 6 through the ventilation hole 71, rainwater enters the sound barrier 6 from the opening of the sound barrier 6. Under the action of heavy rainfall, a large amount of rainwater will enter from the opening of the sound barrier 6. At this time, the rainwater will disrupt the air flow of the sound barrier 6 and affect the air flow inside the sound barrier 6, thereby affecting the dispersion and diversion of the wind. For this reason, the utility model proposes a water retaining plate 8 to solve the above problem.

[0041] For details, please refer to the attached manual. Figure 5 and Figure 6A water retaining plate 8 is installed at the top of the sound barrier 6, and the water retaining plate 8 is used to prevent rainwater from entering from the top opening of the sound barrier 6. A drainage hole 61 is opened on the side of the sound barrier 6.

[0042] It should be noted that by installing a water baffle 8 at the top of the sound barrier 6, rainwater is prevented from entering the sound barrier 6 from the top opening of the sound barrier 6. However, under the influence of heavy rainfall, some rainwater will still enter the sound barrier 6 from the ventilation hole 71. In order to avoid the impact of residual rainwater in the sound barrier 6, a drainage hole 61 is provided to discharge some rainwater that enters the sound barrier 6, thereby preventing rainwater from remaining in the sound barrier 6 and affecting the normal use of the sound barrier 6.

[0043] In the above technical solution, when encountering continuous strong winds, the strong winds will continue to blow towards the sound barrier 6. However, since the main function of the sound barrier 6 is to reduce the propagation of noise, the large-aperture ventilation holes 71 may allow more sound waves to pass through, thereby reducing the sound insulation effect of the sound barrier 6. Therefore, in order to ensure the sound insulation effect of the sound barrier 6, the aperture of the ventilation holes 71 is usually set to be smaller. At this time, continuous strong winds blow towards the sound barrier 6. Since the aperture of the ventilation holes 71 is small, the wind cannot pass through quickly, and a higher wind pressure will be formed on the side of the sound barrier 6. This will cause the sound barrier 6 to be subjected to additional lateral forces, increase the structural load, and even have the risk of damage. For this reason, the utility model proposes a ventilation adjustment mechanism 9 for adjusting the size of the air inlet aperture in a continuous strong wind environment.

[0044] For details, please refer to the attached manual. Figures 6 to 8 A ventilation adjustment mechanism 9 is provided on the side of the sound barrier 6, and the ventilation adjustment mechanism 9 is used to adjust the air inlet aperture. The ventilation adjustment mechanism 9 includes a side seat 91, and the side seat 91 is installed on the side of the sound barrier 6. A number of ventilation holes 92 are provided on the side seat 91, and the several ventilation holes 92 are aligned with the corresponding ventilation holes 71 in the horizontal direction, and the ventilation holes 71 and the ventilation holes 92 have the same size and specifications. A number of vertically sliding baffles 93 are provided in the side seat 91, and the several baffles 93 are located in the corresponding ventilation holes 92, and an air inlet notch 931 is provided at the bottom of the baffle 93.

[0045] It should be noted that when encountering continuous strong winds, in order to ensure that the wind can pass through quickly, the sliding baffle 93 can be used to increase the air inlet aperture so that more wind can pass through quickly, avoiding the problem of the wind not being able to pass through quickly causing the sound barrier 6 to be subjected to additional lateral force, thereby increasing the load on the sound barrier 6.

[0046] Further, refer to the instructions attached Figures 6 to 8A driving mechanism 10 is provided on the side seat 91, and the driving mechanism 10 is used to drive the baffle 93 to slide and adjust the air inlet aperture. The driving mechanism 10 includes a side panel 101, and the side panel 101 is hinged on the side seat 91. A connecting piece 102 is installed at the end of the side panel 101, and the end of the connecting piece 102 away from the side panel 101 is connected to a horizontal bar 103. A vertical bar 104 and an elastic piece 105 are installed at the bottom of the horizontal bar 103, and the vertical bar 104 is fixedly connected to the corresponding baffle 93.

[0047] It should be noted that the connecting member 102 is a connecting rope and the elastic member 105 is a spring. When subjected to continuous strong winds, the strong wind will drive the side panel 101 to flip over, so that the side panel 101 can pull the horizontal bar 103 upward through the connecting rope while flipping, and pull the vertical bar 104 through the horizontal bar 103 to drive several baffles 93 to slide vertically upward, thereby increasing the air inlet aperture, allowing more wind to pass quickly to disperse and reduce the pressure of the wind on the sound barrier 6.

[0048] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
