Concrete guard fence machining equipment and using method thereof

Abstract

The invention provides concrete guard fence machining equipment. The concrete guard fence machining equipment comprises a mold and a vibrating feeding device. The mold comprises two side walls and two end walls. The two end walls are arranged at the two ends of the side walls correspondingly and connected with the ends of the side walls. Guide rails are arranged at the tops of the two side walls correspondingly. The two guide rails are arranged in parallel. The vibrating feeding device is movably arranged on the guide rails and comprises a base, a hopper and a vibrating unit. The base is matched with the top of a guard fence in shape and movably arranged on the guide rails. The hopper is arranged on the upper portion of one end of the base. The base is provided with a feeding inlet matched with the bottom of the hopper. The vibrating unit is arranged at the other end of the base. The concrete guard fence prepared through the concrete guard fence machining equipment is low in bottom density, small in gap number, low in water absorbing capacity, not prone to frozen damage and suitable for being applied to the northern region of China, and the service life of the concrete guard fence is 20 years or above and is 7 times or more that of concrete guard fences in the prior art.

Description

technical field [0001] The invention belongs to concrete guardrails, and in particular relates to a concrete guardrail processing equipment and a using method thereof. Background technique [0002] Concrete guardrail is a wall-type guardrail structure with a certain shape, and it is a permanent load-bearing structure. When the car collides with the guardrail, because the guardrail is rigid and basically not deformed, the energy during the collision process is mainly absorbed by the contact and sliding of the car with the guardrail surface, climbing and turning along the guardrail surface. [0003] In China, concrete guardrails are used on a large scale. When processing the concrete guardrail of the prior art, in order to facilitate pouring and handle the top surface of the guardrail, the mold is usually inverted, the bottom of the concrete guardrail is on the top, and the top of the concrete guardrail is poured downward, that is, the concrete guardrail is poured upwards.

Problems solved by technology

In areas where there is a lot of snow in winter in northern my country, ice and snow tend to accumulate on the concrete guardrail. The bottom of the concrete guardrail cast by this method is loose and full of small holes. Once the rain and snow melt, water can easily enter the pores at the bottom of the concrete guardrail. Condensed into ice, after repeated freezing in winter, the bottom of the concrete guardrail is easily damaged by freezing
