[0023] Reference Figure 1-7 , a combined corrugated beam guardrail for the central divider of a highway, comprising a fixed foundation 1, a plurality of fixed columns 2, a transverse installation assembly 3, corrugated plates 4, and a connection assembly 5. The fixed foundation 1 is fixedly arranged on the ground foundation to provide stable support. The fixed columns 2 penetrate through the fixed foundation 1 and extend into the ground foundation, which can increase the connection area of the fixed columns 2, thereby enhancing the stability of the overall structure. The transverse installation assembly 3 is arranged on the top of the fixed columns 2 for installing the corrugated plates 4. At the same time, when the corrugated plates 4 are impacted, the impact force can be dissipated and the impact strength can be reduced to achieve a better protection effect of the guardrail. The corrugated plates 4 are respectively arranged on both sides of the transverse installation assembly 3 to protect and guide vehicles. The connection assembly 5 is arranged inside the fixed columns 2. The connection assembly 5 can strengthen the connection strength between the fixed columns 2 and the ground foundation, thereby improving the overall connection strength of the guardrail and reducing the situation where the fixed columns 2 are separated from the ground foundation when the corrugated plates 4 are impacted. Thus, it can effectively prevent vehicles from crossing or hitting the central divider during driving, ensure driving safety, and is convenient for installation, thereby improving the installation efficiency and shortening the construction period.

[0024] In some embodiments, the fixed column 2 includes a column body 21, a connection hole 22, a rotation cavity 23, and at least three adjustment slots 24. The column body 21 penetrates through the fixed foundation 1 and extends into the ground foundation. The fixed foundation 1 can be formed by concrete pouring, which can improve the connection strength between the fixed foundation 1 and the column body 21, thereby enhancing the overall structural strength. The column body 21 may be provided with a cone to reduce the resistance of the column body 21 when driving into the ground foundation. The connection hole 22 is coaxially arranged on the column body 21. The rotation cavity 23 is arranged at the bottom of the connection hole 22. Three adjustment slots 24 are annularly arranged on the rotation cavity 23. A connection assembly 5 is arranged between the plurality of adjustment slots 24 and the rotation cavity 23.

[0025] In some embodiments, the connecting assembly 5 includes a rotating disk 51, at least three connecting blocks 52, a spiral ring strip 53, a rotating groove 54, a limit plate 55 and a rotating rod 56. The rotating disk 51 can be rotatably arranged in the rotating cavity 23, and the connecting block 52 is plugged into the adjusting groove 24. The three connecting blocks 52 are arranged at the bottom of the rotating disk 51 and can slide in the adjusting groove 24 following the rotation of the rotating disk 51, thereby being inserted into the foundation, which can increase the connection points between the guardrail and the foundation, thereby enhancing the connection strength between the connecting assembly 5 and the fixed column 2, and further improving the overall stability of the guardrail.

[0026] The spiral ring strip 53 is arranged at the bottom of the rotating disk 51, and a plurality of rotating grooves 54 are arranged at equal intervals on the top of the connecting block 52, and the rotating grooves 54 are plugged into and matched with the spiral ring strip 53. By rotating the spiral ring strip 53, the connecting block 52 and the spiral ring strip 53 can be connected through the plurality of rotating grooves 54, so that the rotation of the spiral ring strip 53 drives the plurality of connecting blocks 52 to slide at the same time, thereby improving the stability of the connecting block 52 when sliding.

[0027] The cross section of the rotating groove 54 can be I-shaped, and the limiting plate 55 is arranged on the side of the connecting block 52 away from the rotating groove 54, which can limit the sliding range of the connecting block 52 and prevent the connecting block 52 from sliding out of the rotating groove 54, thereby further improving the safety of the guardrail.

[0028] The rotating rod 56 is fixed on the top of the rotating disk 51. The cross-section of the rotating rod 56 can be a regular hexagon, which can be adapted to the external rotating equipment and is convenient for connection with the external rotating equipment. The rotating rod 56 is rotated, so that the installer can easily adjust and fix the connecting component 5, thereby improving the installation efficiency and construction speed.

[0029] By rotating the rotating rod 56, the rotating disk 51 is rotated in the rotating cavity 23, and the spiral ring strip 53 is plugged into the rotating groove 54 to drive the connecting block 52 to slide in the adjusting groove 24, so that the connecting block 52 protrudes from the adjusting groove 24 and is inserted into the foundation, thereby increasing the connection points between the fixed column 2 and the foundation, enhancing the connection strength between the fixed column 2 and the foundation, and avoiding complex operations, low construction efficiency, and poor foundation connection strength during the pre-embedded fixed column 2.

[0030] In some embodiments, the lateral mounting assembly 3 includes two mounting rings 31 and two mounting plates 32. The two mounting rings 31 are symmetrically arranged on both sides of the top of the fixing column 2. A corrugated plate 4 is provided on the mounting rings 31. The mounting rings 31 can provide a stable mounting position for the corrugated plate 4. Through its symmetrical layout, it can achieve uniform support for the corrugated plate 4. At the same time, when the corrugated plate 4 is impacted, the mounting rings 31 have a certain elastic deformation, which can preliminarily reduce the impact force.

[0031] Two mounting plates 32 are symmetrically arranged at both ends of the top of the fixed column 2, and an installation ring 31 is arranged between the two mounting plates 32. Wave plates 4 are connected to both sides of the mounting plates 32. The two mounting plates 32 can increase the connection points between the wave plates 4 and the fixed column 2, thereby enhancing the connection strength between the wave plates 4 and the fixed column 2, and realizing further support and guidance for the wave plates 4.

[0032] In some embodiments, the mounting plate 32 includes a fixing part 321, a sliding groove 322, and a sliding part 323. The fixing part 321 is arranged at one end of the top of the fixed column 2, providing a stable installation foundation for the mounting plate 32. The sliding grooves 322 are arranged on both sides of the fixing part 321. The sliding grooves 322 can provide a sliding track for the sliding parts 323 of the wave plates 4. The sliding parts 323 are arranged on the side of the wave plates 4 close to the mounting plate 32, and the sliding parts 323 are in sliding fit with the sliding grooves 322. The sliding fit between the sliding parts 323 and the sliding grooves 322 not only realizes the flexible installation of the wave plates 4 on the mounting plate 32, but also dissipates part of the impact energy through sliding friction, improving the protection effect of the guardrail. In order to further enhance the stability of the wave plates 4 on the mounting plate 32, a plurality of elastic members 324 are arranged between the bottom wall of the sliding groove 322 and the sliding parts 323. These elastic members 324 can elastically deform when subjected to impact, thereby absorbing and dissipating the impact energy and reducing the degree of damage to the wave plates 4.

[0033] In some embodiments, the mounting plate 32 further includes a sliding rod 325 and a plurality of buffer holes 326. The elastic members 324 are sleeved on the sliding rod 325. The plurality of buffer holes 326 are arranged on the bottom wall of the sliding groove 322, and the buffer holes 326 are coaxially inserted and matched with the sliding rod 325. The insertion fit between the sliding rod 325 and the sliding groove 322 can provide stable support for the elastic members 324, enabling the elastic members 324 to deform in a set direction when subjected to impact.

[0034] In some embodiments, the mounting plate 32 further includes a sealing plug 327 and a fragile plate. The sealing plug 327 is arranged at the end of the sliding rod 325 and is slidably and sealingly arranged in the buffer hole 326. Gas is filled between the sealing plug 327 and the buffer hole 326. The gas can be a gas such as oxygen that is easily expandable under pressure. The fragile plate is arranged on the end face of the fixing part 321 and is communicated with the buffer hole 326. The fragile plate can be made of a material such as glass that is easily broken under strong pressure. Thus, when subjected to severe impact, the sliding rod 325 drives the sealing plug 327 to slide in the buffer hole 326, quickly compressing the gas filled between the sealing plug 327 and the buffer hole 326. The gas expands under pressure, impacting the fragile plate and causing the fragile plate to break, thereby releasing the gas in the buffer hole 326, further dissipating the impact energy, improving the buffering effect of the guardrail, protecting the guardrail and the vehicle from damage, and at the same time reducing the force exerted by the wave plates 4 on the fixed column 2 and preventing the fixed column 2 from separating from the foundation.

[0035] An installation method for a combined corrugated beam guardrail in the central median of a highway, comprising the following steps: S1, Lofting of the fixed column 2 and foundation treatment Perform distance measurement and positioning at the required construction location to determine the accurate position of the fixed column 2.

[0036] Specifically, the spacing can be adjusted using an adjusting plate, and the fractional part of the spacing can be processed using an allocation method. After lofting, the foundation conditions at the position of each fixed column should be investigated. In case of underground pipelines, drainage troughs and other facilities, or when the buried depth of the top of the structure is insufficient, the position of the fixed column should be adjusted according to the actual situation or a concrete foundation should be set up to ensure the structural stability.

[0037] The driving-in method of construction can be adopted to drive the whole fixed column 2 into the foundation to the set depth, ensure that the position of the fixed column conforms to the design document, and is coordinated with the road alignment. The buried depth of the fixed column should also strictly follow the requirements of the design document.

[0038] During specific construction, a scale for indicating the driving-in depth can be marked on the surface of the fixed column 2. When driving in too deep, the fixed column should not be partially pulled out for correction, but should be completely pulled out, and the foundation should be compacted to the requirements of the design regulations and then driven in again. When the fixed column 2 cannot be driven to the required depth, the part of the fixed column above the ground should not be welded, drilled, and the fixed column with a cut-off length should not be used. It is advisable to adopt the drilling method to install the fixed column, or the digging and burying method to install the fixed column, or change it to a concrete foundation according to the requirements of the design change. When using the drilling method for construction, the drilling depth can be determined according to the soil conditions. After the fixed column is fixed, the gap should be filled with mortar or concrete and tamped. The construction should comply with the requirements of JTG / T 3671.

[0039] S2, Adjustment of the connecting component 5 Rotate the rotating rod 56 to drive the rotating disc 51 to rotate in the rotating cavity 23. The spiral ring strip 53 at the bottom of the rotating disc 51 rotates accordingly, driving the connecting block 52 to slide in the rotating groove 54 until the connecting block 52 is firmly inserted into the foundation, enhancing the connection strength between the fixed column 2 and the foundation.

[0040] S3, Installation of the transverse installation component 3 On both sides of the top of the fixed column 2, fix two installation rings 31 respectively, ensuring that the positions of the installation rings 31 are accurate and stable.

[0041] Install two installation plates 32 at both ends of the installation ring 31, so that the middle part of the installation plate 32 is tightly and firmly fixedly connected to the end face at the top of the fixed column 2.

[0042] S4, Preparation for the installation of the corrugated plate 4 Before installing the corrugated plate 4, it is necessary to first install the mounting ring 31 and the mounting plate 32 on the top of the fixed column 2, which can be fixed by bolts. Then, install the corrugated plate 4 on the mounting ring 31 and the mounting plate 32, which can also be fixed by bolts. The connecting bolts between the mounting ring 31, the mounting plate 32 and the fixed column 2 should not be tightened prematurely to facilitate subsequent adjustment. The connecting bolts can be tightened only after the corrugated plate 4 is installed and overall adjusted.

[0043] Connect multiple corrugated plates 4 to each other by splicing bolts to form a longitudinal crossbeam and fix it on the transverse mounting assembly 3. The splicing direction of the corrugated plate 4 should be consistent with the driving direction.

[0044] During the installation process, the connecting bolts and splicing bolts of the corrugated beam should not be tightened prematurely to facilitate adjustment using the oblong holes of the corrugated beam and ensure that it forms a smooth longitudinal and horizontal alignment.

[0045] After the installation is completed, it should be checked whether the connecting bolts and splicing bolts of the corrugated beam are tightened in place.

[0046] The combined guardrail should be end-treated according to the actual situation. The guardrail end should be firmly connected to the corrugated plate 4 by splicing bolts.

[0047] S5, Construction of the fixed foundation 1 The fixed formwork method can be used for construction. During construction, tie or weld the steel bars as required to form a pouring formwork on the foundation. After applying the release agent to the steel formwork, pour concrete into the pouring formwork and the fixed column 2 to ensure that the pouring quality meets the design requirements.

[0048] S6, Formwork removal The formwork removal time should be determined according to the temperature and the concrete strength. In summer, it is advisable to remove the formwork 24 hours after the concrete has finally set and the concrete strength has been determined. In winter, the formwork can be removed when the concrete strength is not less than 5 Mpa. The formwork removal should not damage the surface and edges of the concrete and the formwork should be kept in good condition.

[0049] After formwork removal, if there are honeycombs, pitted surfaces, cracks, and peeling, and it is determined that there are no structural problems, it can be repaired with cement slurry of the same mix ratio, or repaired with repair materials of the same color. Necessary grinding can be carried out. After repair, pay attention to curing to avoid large color differences.

[0050] S7, Installation of attachment facilities Install attachment safety facilities such as reflective films on the guardrail. The construction should be carried out in accordance with the design requirements to ensure safe driving at night.

[0051] The specific working principle is as follows: When the corrugated plate 4 is subjected to the impact force of the vehicle, the corrugated structure of the corrugated plate 4 itself will deform, initially dissipating the impact energy. The corrugated plate 4 moves towards the fixed column 2 under the force, squeezing and deforming the mounting ring 31. The mounting ring 31 will dissipate part of the impact energy and reduce the impact force. At the same time, during the process of the corrugated plate 4 moving towards the fixed column 2, the sliding rod 325 drives the sealing plug 327 to slide in the buffer hole 326, quickly compressing the gas (such as oxygen and other gases that are easy to expand under pressure) filled between the sealing plug 327 and the buffer hole 326. The gas expands under pressure, impacting the fragile plate (such as a glass plate and other materials that are easy to break under strong pressure), causing the fragile plate to break, thereby releasing the gas in the buffer hole and further dissipating the impact energy, enhancing the buffer effect of the guardrail; multiple elastic members 324 are deformed under force. Through the coaxial plug-in fit of the sliding rod 325 and the buffer hole 326, the deformation direction of the elastic members 324 can be restricted, and through the sliding fit of the sliding portion 323 and the sliding groove 322, the impact energy is further reduced. Through the multiple buffer structures, the impact force received by the corrugated plate 4 is reduced, thereby reducing the force exerted by the corrugated plate 4 on the fixed column 2. When the fixed column 2 is installed, by rotating the rotating rod 56, the rotating disk 51 rotates in the rotating cavity 23, thereby driving the connecting block 52 to slide in the adjustment groove 24 until the connecting block 52 is inserted into the foundation, increasing the connection area between the fixed column 2 and the foundation, thereby enhancing the connection strength between the fixed column 2 and the foundation. Therefore, when the connection strength is enhanced and the impact force is weakened, the connection stability between the fixed column 2 and the foundation can be improved, and the fixed column 2 can be prevented from detaching from the foundation.
