In order to strengthen the connection between the pipe pile and the bearing platform or the two sections of pipe piles, a steel supporting plate and a steel skeleton are installed in the pipe pile, and core filling is carried out. The depth of the core is selected depending on the strength of the bond between the core and the tube stake wall. Therefore, the on-site pulling resistance test can measure the bonding strength between the filling core and the tubular pile wall, and provides design parameters for the selection of the filling core depth.
The traditional anti-pulling test generally adopts a vertical anti-pressing pile or a natural foundation as a counterforce device, and the steel beam is used for transferring force between the steel bar for pulling the filling core and the counterforce device. If the bonding strength between the filling core and the pipe pile wall is larger than the side friction resistance between the pipe pile and the pile surrounding soil, the pipe pile and the pile surrounding soil can relatively displace before bonding damage occurs, and a large engineering risk exists (the pipe pile is in the risk of being pulled out).
If the pile wall of the core filling pipe is used as a counterforce device, the pulling-resistant test operation space can be limited by the diameter of the pipe pile and becomes very narrow, and the pulling-resistant devices such as a force transmission steel beam, a jack and the like can interfere with tension steel bars in the core filling to influence the working efficiency.
