Ensure the level of degree of the bridge board meet the requirement. 2. The foundation must be level enough. Level error should not be larger than 5mm. 3. Ensure the clearance and the vertical degree between the post and the girder meet the requirement. 4. If the thickness of ground concrete is thicker than 150mm and the ground strength and the level reach the requirement, expanded bolting could be used to fix. 5.This foundation needs to be built in a secondary grouting. And if only grouting one time, it should be ensured the size for imbedding the anchor bolts; The foundation should be strengthened by enforcing steel bars.
