[0002] At present, in order to prevent vehicles from going out of the highway, workers will install anti-collision guardrails on both sides of the highway when building roads; when constructing anti-collision guardrails, workers first weave steel mesh on both sides of the highway, then place casting molds on the steel mesh, and finally pour concrete into the molds, and remove the molds after the concrete solidifies; when workers pour concrete into the molds, concrete aggregates or slurry can easily fall from the molds and contaminate the ground. In order to facilitate cleaning later, workers will set up protective sheds at the construction site.

[0003] However, when workers are building roads at high altitudes, such as viaduct construction, cross-mountain highway construction, etc., most of them are constructed by splicing prefabricated box girders, and thus it is impossible to set up protective sheds. When pouring anti-collision guardrails on both sides of the prefabricated box girders, concrete aggregate or slurry is easy to fall from the outside of the anti-collision guardrails, causing unpredictable safety hazards to vehicles passing below.

[0011] When the concrete solidifies in the mold, the staff removes the support rods, lifts the support frame with a crane, and then removes the mold; when the mold is removed, the support frame is lowered, and the staff places the support rods between the baffle and the anti-collision guardrail. Later, when the staff cleans the anti-collision guardrail, the concrete aggregate that falls to the outside of the anti-collision guardrail will fall into the collection trough, making it convenient for the staff to clean the anti-collision guardrail after pouring.
