Description

Technical Field

[0001] The present invention relates to the technical field of road construction protection, in particular to a road construction protection structure. Background Art

[0002] Road construction protection measures typically involve installing guardrails at the construction site. Larger construction sites often feature fences, often in conjunction with other safety features like safety cones and flashing lights. Guardrails and fences primarily serve to isolate the construction site, providing protection and enhancing safety along the construction route.

[0003] Road construction noise is mainly caused by construction machinery, and the noise generated usually exceeds the national construction noise threshold, which will affect the normal life and health of surrounding residents. Traditional road construction protection structures such as guardrails and fences cannot solve the problem of construction noise pollution. The existing noise pollution protection measures are to build sound insulation walls, such as the sound insulation walls on elevated roads. The setting of such sound insulation walls can effectively weaken and reduce the noise impact in a certain area. Existing sound insulation wall technology usually adopts perforated plate sound absorption structure. Applying sound insulation wall technology to road construction guardrails and fences can better solve the construction noise problem. However, the existing perforated plate sound absorption structure lacks effective outer layer protection. It occupies a large area during road construction, which can easily cause traffic congestion and easily cause passing vehicles to collide with fences, thereby damaging the sound absorption structure and affecting the noise reduction effect.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example

[0033] like Figure 1-6 As shown, a road construction protection structure proposed in one embodiment of the present invention includes a sound insulation component 100, a base plate 200, a plurality of outer protection units 300, a rubber spring 400 and an elastic connector 500.

[0034] In order to solve the construction noise pollution problem that traditional road construction protection guardrails cannot solve, the present invention adds a sound insulation component 100 to the traditional protection guardrail structure. The setting of the sound insulation component 100 mainly plays the role of isolating the noise generated by the construction site from the inside and outside. The sound insulation component 100 is used to absorb and insulate sound, thereby preventing the noise generated by the construction site from affecting the production and life of nearby residents.

[0035] In order to strengthen the basic structure, the present invention provides a base plate 200. The base plate 200 is used to fix the sound insulation component 100. At the same time, the base plate 200 can also serve as an outer layer protection for the sound insulation component 100. The base plate 200 can be made of polycarbonate impact-resistant board, also known as PC board. PC board has the characteristics of impact resistance and flame retardancy. The average sound insulation value of 6mm thick PC board is 21.5dB and the sound insulation index is 24dB. The main advantages are easy production and certain sound insulation effect. The present invention arranges the base plate 200 as a sandwich, that is, the base plate 200 is between the sound insulation component 100 and the outer protection unit 300, which can well reduce the glare effect of the PC board.

[0036] The construction site of a road is provided with a soundproof wall, which makes the propagation of sound waves have a significant additional attenuation, thereby reducing the noise impact within a certain area where the receiver is located. The design of a soundproof wall can be relatively easy to implement in the existing technology, for example, an elevated soundproof barrier is set up outside the road construction site. However, the existing soundproof walls lack effective protection. Since the construction site occupies the road, it is inevitable that the soundproof walls will collide with each other. The soundproof walls without effective protection are easily damaged under the impact. Therefore, the present invention addresses the problem of lack of effective protection in the existing soundproof wall facilities and designs a road construction protection structure with a plurality of external protection units 300. The plurality of external protection units 300 are evenly arranged on the outer wall of the bottom plate 200 by a rubber spring 400, and the two adjacent external protection units 300 are universally connected by an elastic connector 500. The plurality of external protection units 300, the rubber spring 400 and the elastic connector 500 constitute an anti-collision energy absorption protection for the sound insulation component 100. Structure, when one of the outer protection units 300 collides, the outer protection unit 300 is first pressed down by force, and the rubber spring 400 is stressed. The road construction protection structure with elastic energy absorption and collapse energy absorption can use the kinetic energy deformation generated when a collision occurs to absorb the impact force of the collision. When the collision force is too large, the elastic connector 500 connected to the outer protection unit 300 corresponding to the collision area will be pulled. The elastic connector 500 uses its elastic properties to provide buffering protection. Under multi-layer protection, it can ensure to the greatest extent that the sound insulation component 100 corresponding to this part will not be easily damaged under collision, thereby further ensuring the sound insulation and noise reduction effect of the road construction site.

[0037] The outer protection unit 300 is a regular hexagonal structure as a whole, and the axial direction of the elastic connector 500 is consistent with the diagonal direction of the outer protection unit 300; further, the length of the elastic connector 500 is consistent with the side length of the outer protection unit 300. The elastic connector 500 and the outer protection unit 300 form a regular hexagonal protection net, which provides overall protection for road construction, isolates the inside and outside of the construction site and construction noise, and at the same time, the combination of the outer protection unit 300, the rubber spring 400 and the elastic connector 500 further provides anti-collision protection for the sound insulation component 100.

[0038] like Figure 2As shown, in some embodiments, the sound insulation assembly 100 is composed of a perforated sound absorbing panel 101 , a first sound absorbing layer 102 , a second sound absorbing layer 103 , a first sound insulation layer 104 and a second sound insulation layer 105 in sequence. Specifically, the first sound-absorbing layer 102 is a sound-absorbing non-woven fabric. The sound-absorbing non-woven fabric can reduce the acoustic impedance of the perforated sound-absorbing panel 101 to the same level as the impedance of air, forcing sound waves to pass through the non-woven fabric structure, generating friction. This friction causes kinetic energy loss, thereby achieving the purpose of sound absorption and noise reduction; the second sound-absorbing layer 103 is an aluminum honeycomb core. When sound waves contact the metal surface, they will enter the pores of the honeycomb metal through diffuse reflection, so that the internal vibration of the metal converts the sound waves into heat energy, thereby achieving a sound-absorbing effect; the first sound-insulating layer 104 is sound-insulating cotton, and the second sound-insulating layer 105 is sound-insulating felt. The sound-insulating cotton and sound-insulating felt cooperate to achieve the purpose of bottom-layer sound insulation, thereby reducing and isolating construction noise to the greatest extent; the present invention achieves the purpose of isolating construction noise as a whole through the cooperation of multiple sound-absorbing layers and sound-insulating layers, preventing nearby residents and pedestrians from being disturbed by construction noise.

[0039] In some embodiments, the road construction protection structure further includes columns and a base, the columns are H-shaped steel columns, the base is a concrete base, the columns are fixed on the base at equal distances, and the base plate 200 is fixed between the grooves of the two columns.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, the outer protection unit 300 includes a hexagonal energy absorbing substrate 301, an energy absorbing support 302 and a universal joint 303. The hexagonal energy absorbing substrate 301 includes an arched plate 3011. The outer edge of the arched plate 3011 is connected to a hexagonal hollow concave plate 3012. The arched plate 3011 and the hexagonal hollow concave plate 3012 are made of elastic material and have high impact resistance, toughness and aging resistance. The hexagonal hollow concave plate 3012 has an energy absorbing groove. After the arched plate 3011 is pressed down, the arched plate 3011 generates stress deformation, and the arched plate 3011 and the hexagonal hollow concave plate 3012 themselves are used to absorb energy. The elastic properties provide elastic energy absorption for the hexagonal energy-absorbing substrate 301. A universal joint 303 is respectively provided on the six corners of the hexagonal hollow concave plate 3012. The universal joint 303 is provided to facilitate the connection of the elastic connector 500, ensuring that when it is collided or squeezed, the outer protection unit 300 presses down the rubber spring 400, and the outer protection unit 300 pulls the elastic connector 500. It has a large angular compensation ability and can link and share the stress generated by the collision of the outer protection unit 300 when the outer protection unit 300 and the rubber spring 400 exert elastic stress and change their shape, thereby reducing stress concentration and achieving better protection effect.

[0041] The energy-absorbing support member 302 includes an upper ring plate 3021 connected to the bottom of the arch plate 3011. The bottom of the upper ring plate 3021 is connected to a stress tube 3022 with a wall thickness from large to small from top to bottom. An energy-absorbing groove 30221 is provided on the outer wall of the stress tube 3022. The structural design of the stress tube 3022 is similar to that of an automobile energy-absorbing box, and it mainly plays a role in crush energy absorption protection. The energy-absorbing support member 302 is effectively combined with the hexagonal energy-absorbing base plate 301 to make the structure more compact and the energy absorption effect better.

[0042] The bottom of the stress cylinder 3022 is fixedly connected to the top of the rubber spring 400 , and the bottom end of the hexagonal hollow concave plate 3012 is in contact with the top of the rubber spring 400 .

[0043] like Figure 5 and Figure 6 As shown, in some embodiments, the elastic connector 500 includes a sleeve 501, a first sleeve rod 502 and a second sleeve rod 503, the first sleeve rod 502 and the second sleeve rod 503 have the same length and size, a central hole channel 5011 adapted to the first sleeve rod 502 and the second sleeve rod 503 is provided in the sleeve 501, the first sleeve rod 502 and the second sleeve rod 503 abut against the central hole channel 5011, a plurality of buffer channels 5012 are provided in the sleeve 501 corresponding to the outer circumference of the central hole channel 5011, the buffer channels 5012 are connected to the central hole channel 5011 through a sliding cavity 5013, the first sleeve rod 502 and the second sleeve rod 503 are both provided with a connecting portion 504 adapted to the sliding cavity 5013, and a middle outer wall of the two connecting portions 504 near the sliding cavity 5013 is provided with a buffer channel 5012 sliding fits the sliding block 505, and a buffer spring 506 is pre-installed in the front and back of each buffer channel 5012. A sleeve plug 507 adapted to the buffer channel 5012 is provided at both the left and right ends of the sleeve 501. The outer ends of the first rod 502 and the second rod 503 are respectively connected to the axial diagonal universal joints of the two adjacent outer protection units 300; when the first rod 502 or the second rod 503 is subjected to axial tension, the rod slides in the direction of force, driving the sliding block 505 thereon to slide in the buffer channel 5012. The sliding block 505 will squeeze the buffer spring 506 during the sliding process. When one of the two rods is subjected to axial tension, the buffer springs 506 arranged in the front and back of the buffer channel 5012 are subjected to a certain pressure, and the buffer springs 506 are used to buffer the impact force.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
