Description

Technical Field

[0001] The utility model belongs to the technical field of guardrail laying, and in particular relates to a device for sealing an opening of a highway guardrail column. Background Art

[0002] When constructing highway guardrails, it is necessary to insert the columns into the concrete pavement. When the concrete is air-dried and solidified, the columns are fixed on the pavement. However, gaps are easily generated at the contact points between the columns and the pavement, which causes rainwater to easily penetrate into the roadbed. In the long run, this can easily shorten the service life of the pavement. Usually, steel rings are used to shape cement mortar to seal the holes and gaps. However, due to gaps between the rings and the ground, cement mortar is easy to flow out and cannot be effectively sealed. A device is now proposed that can effectively prevent side leakage of cement mortar during sealing. Utility Model Content
