The utility model discloses an anti-preloading static load test device for a PTC (Positive Temperature Coefficient) tubular pile. The reverse preloading static load test device for the PTC tubular pile comprises a cross beam, a jack, a hoisting rope and two connecting plates, the jack is fixed on a PTC tubular pile to be subjected to a static load test, the cross beam is arranged above the jack and stretches across two pre-buried PTC tubular piles located on the two sides of the PTC tubular pile to be subjected to the static load test, the connecting plate is fixed on the pre-buried PTC tubular piles, and the connecting plate is fixed on the PTC tubular pile to be subjected to the static load test. The two connecting plates are connected to the two ends of the cross beam through the hoisting ropes. The technical problem that the working efficiency of the static load test of the PTC pipe pile is low in the prior art is solved. 本申请公开了一种PTC管桩反预压静载试验装置。所述PTC管桩反预压静载试验装置包括：横梁、千斤顶、吊装绳和两个连接板；所述千斤顶固定在在待静载试验PTC管桩上，所述横梁
