Description

Technical Field

[0001] The utility model relates to the technical field of concrete pipe pile detection, in particular to a prestressed concrete pipe pile anti-pulling detection structure. Background Art

[0002] The existing announcement number is CN 219315845 U. A prestressed concrete pipe pile pull-out detection structure is provided. By setting a locking and limiting mechanism, a bidirectional transmission screw drives the first threaded collar linkage block to move leftward under the action of the thread, and the second threaded collar linkage block moves rightward along the inner wall of the adjustment frame plate under the action of the thread. The limiting arc strip is inserted into the groove body of the connecting steel bar. At the same time, the arc clamping plate drives multiple arc extrusion racks to rub and squeeze the external position of the concrete pipe pile, and then the whole is lifted up by the jack. However, when the above-mentioned locking and limiting mechanism clamps the pipe pile, the transmission screw is required to relatively move and lock the clamping plate. In this way, the pipe pile is clamped and limited only by the clamping plates on both sides, resulting in poor reliability of the clamping of the pipe pile, which may affect the detection effect.
