Enlargement section of RC beam
Planting rebar
It is a six storey reinforced concrete frame structure building.After changing the function of the room, the bearing capacity of the bearing capacity is insufficient and the structure of insufficient bearing capacity is strengthened after the use of the function is changed.
Project overview
The project is located in Shuangliu County of Chengdu, Sichuan, and the experimental building of the Tibetan school garden of Southwest University for Nationalities. It is a six storey reinforced concrete frame structure building.
After changing the function of the room, the bearing capacity of the bearing capacity is insufficient and the structure of insufficient bearing capacity is strengthened after the use of the function is changed.

Construction process
1.Drill hole to the diameter and depth required. The diameter must be in accordance with anchor size.
2.The drill hole must be cleaned with air blower, starting from the bottom of the hole.The drill hole mustbe thoroughly cleaned with steel brush. After brush, to use air blower to clean the drill hole again.
3.Inject resin anchor resin into the hole, starting from the bottom, while slowly drawing back the static mixer. In any case avoid entrapping air. For deep holes extension tubing can be used.
4.Insert the anchor with a rotary motion into the filled drill hole. Some adhesive must come out of the hole.
5.During the resin hardening time the anchor must not be moved or loaded.
