(1) For precast piles (including driven precast piles and static press-in precast piles) and steel piles, the pile top elevation, pile position deviation, driving (or static pressure) depth, hammer stop standard, pile end bearing layer, etc. should be tested.
(2) For cast-in-place piles, the pile top elevation, pile position deviation, pile body quality, pile end bearing layer, etc. should be tested.
(3) For manually dug piles, the excavation size, presence or absence of void soil, geotechnical conditions, and pile end bearing layer should be inspected. For large-diameter rock-socketed piles with single columns and single piles, the lithology should be inspected to see whether there are any adverse geological effects such as cavities, fracture zones, weak interlayers, etc. within a depth range of 3d or 5m below the pile. If necessary, an in-situ load test on the rock foundation of the pile end bearing layer and a pile side friction test should be carried out. The number of test piles should not be less than 1% of the total piles under the same conditions, and should not be less than 3.
(4) Vertical or lateral bearing capacity testing of various piles, piers, and pile walls, including single pile and pile group bearing capacity testing;
(5) Testing of bearing capacity and deformation characteristics of the bearing layer at the bottom of piers;
(6) Structural integrity testing of various piles, piers, and pile walls; HTMLTAGTOKEN OKEN6 (7) considers the interaction between piles and soil or the detection of pile-soil load sharing ratio in composite foundations, and the detection of pile and soil stress-strain;
(8) detection of environmental impacts (such as vibration, noise, soil deformation) during construction;
(9) other detections under special conditions or accident handling.
