[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-6 , the utility model provides a technical solution:

[0037] An assembled high-speed guardrail, comprising

[0038] A sound insulation board 1 and pillars 4 inserted on both sides of the sound insulation board 1;

[0039] The inner side of the column 4 is provided with a plug-in slot 3, and the two ends of the sound insulation board 1 are plugged into the inside of the plug-in slot 3, and the sound insulation board 1 and the column 4 are plugged and fixed by fixing studs 2; the sound insulation board 1 is a plate-shaped structure made of PC material, and the plate is widely used in highway sound insulation board due to its excellent sound insulation effect, which can block the noise generated by the running of vehicles on the highway to a certain extent, avoiding affecting the residents on both sides of the road;

[0040] The bottom of the column 4 is provided with a mounting foot 5; the mounting foot 5 is provided with a mounting hole, and an expansion wire can be inserted into the inside to fix it to the road surface;

[0041] In the technical solution, one side of the column 4 is preferably connected to a buffer protection member 6 .

[0042] The buffer guard 6 includes an energy absorption box 8, an installation back plate 9, a snap-in hole 10, a buffer spring 11 and a buffer plate 12. A reinforcing rod 7 is arranged on the side of the buffer plate 12 close to the column 4, and one side of the reinforcing rod 7 is connected to the buffer spring 11, the other end of the buffer spring 11 is connected to the energy absorption box 8, and the other end of the energy absorption box 8 is connected to the installation back plate 9. The snap-in hole 10 is arranged on the installation back plate 9, and the buffer guard 6 is snap-connected with the column 4 through the snap-in hole 10. In this way, when in use, if a vehicle on the highway loses control and hits the guardrail, due to the buffer guard 6 arranged on the inner side of the guardrail, the vehicle will first hit the buffer guard 6, and the buffer plate 12 arranged on the outermost side of the buffer guard 6 will first contact the vehicle, and then the impact force will be transmitted to the buffer spring 11 through the buffer plate 12. A plurality of buffer springs 11 are arranged, and the plurality of buffer springs will first use their own elastic force to absorb and buffer the impact force. To reduce the impact force, if the buffer spring fails to absorb the impact force, the impact force will be transmitted again to the energy absorption box 8 connected to the other end of the buffer spring. There are a plurality of energy absorption boxes 8, which are divided into two rows, upper and lower, and connected to the buffer plate 12 in turn through the buffer spring 11. The energy absorption box 8 is a square box structure made of aluminum alloy. There are crushing induction grooves or crushing points on the energy absorption box 8 to guide and control deformation, thereby optimizing energy absorption and absorbing the energy generated by external impact again, so as to absorb and buffer the impact force of the vehicle by using multiple buffer structures, avoiding the vehicle impact damaging the guardrail and rushing out of the road to cause greater safety damage, and the double buffer protection ensures that when the vehicle hits the guardrail, it will not directly collide with the hard guardrail, thereby minimizing the damage to the vehicle caused by the impact, avoiding the impact causing greater harm to the occupants, and improving the safety of the driver and passengers;

[0043] In this technical solution, further, preferably

[0044] A clamping assembly is provided at the connection between the column 4 and the buffer protection member 6, and the clamping assembly includes a clamping block 13, a limit block 14 and a rotating shaft 15. The clamping block 13 is arranged to fit the side of the column 4, and the limit block 14 is arranged on the outer side of the clamping block 13. The limit block 14 is connected to the clamping block 13 through the rotating shaft 15, and the limit block 14 can rotate relative to the rotating shaft 15. The clamping block 13 and the limit block 14 have the same shape and size. The clamping block 13 and the limit block 14 have the same shape as the clamping hole 10 on the mounting back plate 9, and the length and width of the clamping block 13 and the limit block 14 are smaller than the length and width of the clamping hole 10.

[0045] During installation, when the limit block 14 is rotated to the vertical setting and the angle coincides with the clamping block 13, the clamping block 13 and the limit block 14 are then inserted into the inside of the clamping hole 10 at the same time. After insertion, the clamping block 13 fits with the clamping hole 10, and the limit block 14 is inserted to the outside of the clamping hole 10. Then the limit block 14 continues to rotate to be horizontally clamped on the outside of the clamping hole 10. After insertion, the gravity of the buffer guard 6 acts on the limit block 14 to form a pulling force, so that the limit block 14 itself will not rotate, thereby fixing the buffer guard 6. When the buffer guard 6 needs to be disassembled and replaced, it is only necessary to force the limit block 14 to the vertical angle, and then remove the clamping block 13 and the limit block 14 from the inside of the clamping hole 10, so that the buffer guard 6 can be separated from the column 4. The operation is very simple and quick.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
