Technical solutions for ground anchor construction
Jul 06, 2022| Technical solutions for ground anchor construction:
After the preparation of various work, the ground anchor pile (foundation ground screws) is installed on the pile machine, and the ground anchor pile is connected with the pile machine with a pin shaft of ¢16; After connection, the level and perpendicularity of the pile machine are corrected with a magnetic level ruler, and the pile is drilled after meeting the requirements as shown below.
Installation requirements for foundation ground screws.
In the process of drilling piles, first start the alignment, drill to a third of the depth, and observe whether the anchor pile is biased; If there is a deviation, adjust to one-half and then observe. After correcting the error, drill to the depth specified in the design, exposing the natural ground 100~ 150mm. As shown in the figure below, the horizontal height difference between the anchor ends of a single array should be less than 10mm.
Foundation ground screw construction inspection.
After the construction of a single array is completed, the self-inspection form is filled in, and the anchor pile is concealed for acceptance and inspection.
