[0033] Embodiment 1:

[0034] A spliced ​​anti-collision buffer guardrail for municipal engineering, such as Figure 1 to Figure 2 As shown, it includes a plurality of guardrail bodies 1, each guardrail body 1 is respectively fixedly connected with a first column 201 and a second column 202 on both sides for connecting with other guardrail bodies 1, a receiving component is provided on the first column 201, and an inserting component is provided on the second column 202, and two adjacent guardrail bodies 1 are inserted into the receiving component through the inserting component to form a detachable connection structure. The inserting component includes two groups of plug blocks 209 fixedly connected to the side wall of the second column 202, and the two groups of plug blocks 209 are provided with receiving grooves on the opposite sides, and have a first chamfered surface on the opposite side and the side facing the receiving component. The receiving component includes two placement holes 203 opened on the side wall of the first column 201 and matching with the two groups of plug blocks 209. The two placement holes 203 are each provided with a movable groove 204 on the opposite sides thereof. A movable block 206 is slidably arranged in each movable groove 204. The opposite sides of the two movable blocks 206 are connected to one end of a spring 207, and the other end of the spring 207 is connected to the movable groove 204. The two movable blocks 206 are each connected to a fixed block 208 on the side away from each other. The fixed block 208 has a second chamfered surface matched with the first chamfered surface of the plug block 209. A pull rod 205 is fixedly connected to the movable block 206 in a direction perpendicular to the first column 201. A notch that enables the pull rod 205 to move up and down is opened on the first column 201, and the notch is connected to the movable groove 204. The pull rod 205 extends from the notch to the outside of the first column 201.

[0035] When it is necessary to connect two adjacent guardrail bodies 1, the plug block 209 is inserted into the placement hole 203. At this time, the first chamfered surface of the plug block 209 contacts the second chamfered surface of the fixed block 208, pushing the fixed block 208 and the movable block 206 to retract into the movable groove 204 and squeeze the spring 207.

[0037] Embodiment 2:

[0038] On the basis of Example 1, the scheme in Example 1 is further detailed and introduced in combination with the following specific working method.

[0039] As a preferred embodiment, the buffer plate 304 is composed of a first protective plate 3041, a second protective plate 3042 and a second buffer spring 3043, and a plurality of second buffer springs 3043 are clamped and fixed between the first protective plate 3041 and the second protective plate 3042. More specifically, the second buffer spring 3043 and the first buffer spring 305 are both composed of a plurality of groups of spring dampers.

[0041] When the buffer plate 304 is hit, the second buffer spring 3043 can provide the first buffer for the impact force generated by the impact. At the same time, the buffer plate 304 will move along the limit block 306 through the movable block 307, so that the buffer plate 304 drives the connecting rod 303 to swing, thereby pushing the sliding block 302 to move along the outer wall of the limit rod 301 and squeezing the first buffer spring 305. Under the action of the first buffer spring 305, the impact force is buffered for the second time, thereby reducing the damage to the guardrail body 1 and the vehicle, reducing the damage caused by the accident, and reducing economic losses.
