As shown in fig. 2, the lower part of the upright post 4 is fixedly connected with a mounting plate through a fastening bolt, and the mounting plate is fixedly connected with the ground through the fastening bolt. The inside chamber that holds that opens of stand 4, the pre-buried post 401 of pre-buried in ground that is equipped with under stand 4, the intracavity that holds in stand 4 can be stretched into to the top of pre-buried post 401, and pre-buried post 401 is pre-buried in the length of ground account for 1/3 of whole pre-buried post 401 length, specifically is the long 45cm of pre-buried post 401, and pre-buried length of going into in the ground is 15 cm. Simultaneously the length that embedded column 401 stretched into stand 4 accounts for 5/8 of this stand 4 length, and the length that specifically stretches into the holding chamber for embedded column 401 is 25cm, and the length of stand 4 is 40 cm.
The left side of stand 4 is equipped with baffle 2, and baffle 2 adopts the steel sheet that 2cm is thick in this embodiment, and the sponge layer that bonds on the surface of 2 right side walls of baffle, and it is shown with fig. 3 to combine, and the bottom integrated into one piece of baffle 2 has cylindric support column 201, and the lower part integrated into one piece of support column 201 has resisting board 502 simultaneously, and fastening bolt fixedly connected with installation base 5 is passed through to the bottom of support column 201, and installation base 5 passes through fastening bolt and ground fixed connection. The upper surface of mounting base 5 passes through two cardboard 501 of the type of falling L of fastening bolt fixedly connected with, and two cardboard 501 of the type of falling L set up and have the interval that supplies support column 201 to pass through between two cardboard 501 about the longitudinal axis symmetry of support column 201, and cardboard 501 constitutes the structure of draw-in groove with mounting base 5, supports board 502 and is located the draw-in groove.
As shown in fig. 2, a buffer portion 3 is provided between the upright post 4 and the baffle 2, and the buffer portion 3 includes a sleeve 302 fixedly connected to the right side wall of the baffle 2, an insertion rod 303 fixedly connected to the left side wall of the upright post 4, and a buffer spring 301. Inserted bar 303 and sleeve 302 horizontal sliding fit specifically are: the inside wall of sleeve 302 pastes with the outside wall of inserted bar 303, and when guardrail 1 received the striking, inserted bar 303 slided towards baffle 2's direction in sleeve 302, and buffer spring 301's both ends rigid coupling respectively is on the left side wall of stand 4 and the right side wall of baffle 2 and buffer spring 301 cover is established on sleeve 302 and inserted bar 303. The top of stand 4 and the top of baffle 2 all have first pull ring 402 through the fastening bolt rigid coupling, and it has chain 403 to all twine on first pull ring 402, specifically is: both ends of the chain 403 are respectively wound around the first tab 402 at the top of the upright 4 and the first tab 402 at the top of the apron 2.

Through the cooperation of guardrail, buffer spring 301 and baffle 2, reach the purpose that reduces the vehicle and break through the guardrail.
Example two:
the difference between the second embodiment and the first embodiment is that, as shown in fig. 6, a separation foam plate 304 is disposed between two adjacent sleeves 302 at the same horizontal position, two ends of the separation foam plate 304 are respectively and fixedly connected with fixing holes through iron wires, the fixing holes and the sleeves 302 are integrally formed, two ends of the buffer spring 301 are respectively and fixedly connected to the fixing block and the upright post 4, a foam rod 305 is further disposed on the sleeve 302 between the baffle 2 and the separation foam plate 304, and the connection mode between the foam rod 305 and the sleeve 302 and the separation foam plate 304 are the same and are not repeated here. The foam plate 304 and the foam rod 305 are separated to form two buffer barriers, so that the inertia impact of the vehicle on the baffle plate 2 is reduced, and the situation that the vehicle breaks through the baffle plate 2 is further prevented; with reference to fig. 4 and 5, two blocking rods 6 are fixedly connected to the surface of one side of the baffle plate 2 far from the guardrail 1, the blocking rods 6 are all obliquely arranged and the middle points of the blocking rods coincide, the back of the baffle plate 2 forms an X-shaped structure, a supporting rod 7 obliquely arranged towards the baffle plate 2 is embedded in the ground of one side of the baffle plate 2 far from the guardrail 1, and the other end of the supporting rod 7 is fixedly connected with the intersection point of the blocking rods 6 on the baffle plate 2 through a fastening bolt.
The specific implementation process is as follows:
inertia impulsive force of vehicle drives inserted bar 303 towards baffle 2 one side horizontal slip to buffer spring 301 that makes receives the compression, and then lets buffer spring 301 provide a buffering to guardrail 1, thereby provides a buffering barrier to the vehicle, prevents that the vehicle from breaking through guardrail 1. When the vehicle continues to displace under the action of inertia impact force, the foam plate 304 and the foam rod 305 are separated to provide two buffer barriers for the vehicle, so that the inertia impact force of the vehicle is reduced. After the vehicle contacts the baffle 2 under the action of inertial impact force, the baffle 2 is matched with the supporting rod 7, the zipper 801 and the clamping groove to form a buffer net consisting of the baffle 2, so that the vehicle is prevented from breaking the baffle 2.
