The invention relates to a prestress high-strength concrete pipe pile. The prestress high-strength concrete pipe pile comprises a framework, a concrete outer layer, a first end, a second end, an inserting head, locking type adjusting units and linkage rods, wherein the framework is wrapped with the cylindrical concrete outer layer, the first end is installed at the upper end of the concrete outerlayer, the second end is installed at the lower end of the concrete outer layer, the inserting head is installed at the lower end of the second end, the locking type adjusting units are evenly arranged on the framework in the circumferential direction of the framework, and the linkage rods are connected between the locking type adjusting units arranged from top to bottom. The problems that in a traditional erecting mode, the positions of built-in reinforcing steel bars are unstable, the distances between the built-in reinforcing steel bars are not easy to control, the built-in reinforcing steel bars are prone to deviating under the huge impact force of grout in the later period of grouting, the built-in reinforcing steel bars in a pile deviate, the strength in the pile is different, and when the pipe pile is driven underground, huge hammering force may cause damage to the inserting head and the like are solved.
本发明涉及一种预应力高强度混凝土管桩，包括骨架、混凝土外层、第一端头、第二端头、插入头、锁定式调节单元和联动杆，所述的骨架外部包裹有筒状的混凝土外层，混凝土外层的上端安装有第一端头，混凝土外层的下端安装有第二端头，第二端头的下端安装有插入头，骨架上沿其周向均匀设有锁定式调节单元，且从上往下布置的锁定式调节单元之间连有联动杆。本发明可以解决传统架起方式的内置钢筋位置不稳定，且彼此之间的距离不易控制，后期在灌浆时，在浆液的巨大冲击力下内置钢筋容易发生偏位的情况，桩内的内置钢筋位置偏移容易出现桩内强度不同的情况，且管桩打入地下时，巨大捶打力可能对插入头造成破损等情况。
