Retard-bonded prestressed fender post and construction method thereof
The invention discloses a retard-bonded prestressed fender post and a construction method thereof, and aims to solve the problems that in the prior art, one side of a row pile is pressed by a soil body behind a pit, so that only the surface, in contact with or opposite to the soil body, of the row pile is pressed by the soil body (namely an area A and an area B); the problem that the bending resistance efficiency of the row piles is low due to the fact that the pressure borne by the row piles on the two sides perpendicular to the soil body is small (namely the area C and the area D) and the performance cannot be brought into full play is solved. The technical problem is solved through the following technical scheme that pile body concrete and a steel reinforcement cage are included, the steel reinforcement cage is arranged in the pile body concrete, a plurality of common steel bars are arranged in the circumferential direction of the steel reinforcement cage, spiral stirrups are arranged on the peripheries of the common steel bars in a surrounding mode, and a plurality of retard-bonded prestressed tendons are arranged in the steel reinforcement cage; the retard-bonded prestressed tendon comprises a sleeve, a retard-bonded agent is arranged in the sleeve, and a plurality of prestressed tendons are arranged in the sleeve in a penetrating mode.
本发明公开了一种缓粘结预应力围护桩及其施工方法，旨在解决现有技术中排桩一侧受到坑后土体的压力，使得排桩只有与土体接触的或者相对的面受到土体的压力（即区域A和区域B），而与土体垂直的两侧的排桩受到的压力较小（即区域C与区域D），无法充分发挥性能，使得排桩抗弯效率低的问题。本发明通过以下技术方案解决上述技术问题：桩身混凝土和钢筋笼，钢筋笼设置在桩身混凝土内，钢筋笼的圆周方向设置有若干根普通钢筋，若干根普通钢筋外围绕设有螺旋箍筋，钢筋笼内设置有若干根缓粘结预应力筋；缓粘结预应力筋包括套筒，套筒内设置有缓粘结剂，套筒内贯穿设置有若干根预应力筋。
