Problems solved by technology
[0004] However, the base of the anti-collision barriers used in cities is usually fixed on the ground with expansion bolts. When the anti-collision barriers are hit, not only the anti-collision plates and columns are deformed and need to be disassembled and replaced, but also urban roads are usually made of asphalt or concrete pavement. , when the impact force is large, the holes for fixing the expansion bolts are deformed, causing the expansion bolts to loosen, resulting in a decrease in the stability and firmness of the base. The base must be removed together, and the ground must be repaired while replacing the expansion bolts. Troublesome operation, time-consuming and labor-intensive

Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0036] This embodiment discloses a kind of anti-collision barrier for municipal engineering, such as figure 1 As shown, it includes several bases 2 arranged at intervals along the road direction, columns 3 fixed to the upper end of the base 2 by bolts, and beams 31 fixedly connected between two adjacent columns 3; wherein, the beams 31 are provided with two upper and lower , between the two beams 31, several anti-collision bars 32 are fixed side by side along the vertical direction.
[0037] Such as figure 1 , figure 2 As shown, a number of corresponding rectangular installation pits 11 are dug on the pavement layer 1 of the road along the arrangement direction of the crash barriers, and the base 2 includes two fixing seats 21 placed downwards in the installation pits 11, arranged on two The supporting base 22 between the fixing bases 21. The two fixing ...

The invention provides an anti-collision guardrail for municipal engineering. The anti-collision guardrail for the municipal engineering comprises a base, vertical columns and cross beams; the base comprises an inverted Y-shaped upper fixing part, a left supporting part and a right supporting part, and expansion bolts penetrating toward the two sides and fixed into a pavement layer are correspondingly arranged on the inner sides of the left supporting part and the right supporting part. The base is arranged in an installation pit on the pavement layer, and the left supporting part and the right supporting part are fixed to the pavement layer on the two sides of the installation pit correspondingly by the expansion bolts; a triangular stable structure is formed among the upper fixing part,the left supporting part and the right supporting part, and stability of the vertical columns when being impacted is enhanced. When one side of the anti-collision guardrail is impacted, the inner wallof the corresponding side of the installation pit is extruded by the left supporting part or the right supporting part under action of impact force, so that the size of the installation pit is changed, the left supporting part and the right supporting part can be deformed accordingly under action of the elastic deformation capacity, so that the base is enabled to remain tightly attached to the installation pit, and stability of the base is enhanced.
Description
technical field [0001] The invention relates to the technical field of anti-collision barriers, in particular to an anti-collision barrier for municipal engineering. Background technique [0002] The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, and various pipelines closely related to life. Among them, urban roads have become more and more congested with the increase of vehicles in recent years. At present, street guardrails are often used in cities to maintain traffic order. Although the speed of vehicles in cities is significantly reduced by the speed limit, it is still There will be a traffic accident of a vehicle crashing into the guardrail. [0003] At present, the Chinese patent document with the application publication number CN109577250A in the prior art discloses a municipal street anti-collision guardrail, including a base, a support seat arranged...
