In traditional construction technology, the casting of cast-in-place reinforced concrete guardrails of bridges is generally carried out by manual hand-held vibrators.

[0003] The cast-in-place guardrail of the bridge is vibrated by a handheld vibrator, which has the following disadvantages:

[0004] 1. The handheld vibrator is mainly determined by the workers' construction experience, among which the lifting speed, vibration time, vibration radius, insertion position, etc. are quite random, and it is easy to have missed vibration and over-vibration;

[0005] 2. Handheld vibrators are generally single-headed, with low construction efficiency and high labor intensity;

[0006] 3. The steel bars of cast-in-place reinforced concrete guardrail are dense, and manual judgment is inaccurate, requiring multiple adjustments, which wastes time;
