Inspection of pile foundations
The pile position deviation of the pouring pile must comply with the regulations, and the pile top elevation is at least 0.5m higher than the design standard.
The quality of pile bottom clearance has different requirements according to different pile forming processes and should be implemented according to the requirements of the specification. Per pour
Note 50m3 must have 1 set of specimens, and piles smaller than 50m3 must have 1 set of specimens per pile.
Engineering piles should be tested for bearing capacity. For foundation design gradeS or complex geological conditions,
Piles with low pile quality reliability should be inspected by means of static load testing to inspect piles
The number should not be less than 1% of the total number, and should not be less than 3, when the total number of piles is not less than 50, it should not be less
in 2 roots.
Pile foundation reinforcement inspection:
Check the length and spacing of the reinforcement cage; the type, number of specifications, and spacing of the main reinforcement; the specifications of the stirrup varieties, welding points, protective layer, thickness, etc
Check the pile tip, size, plate thickness, wing height, weld seam, height
Quality problems often occur
The outer reinforcement of the independent foundation base plate reinforcement must be closed
No standing water is allowed in natural foundation pits
